This general session of the Energy, Resources and the Environment (ERE) division provides an overview of its multi- and interdisciplinarity, which is essential to tackle challenges of the future. Beside others, this is to provide adequate and reliable supplies of affordable energy and other (geo-)resources, obtained in environmentally sustainable ways, which is the basis for economic prosperity, environmental quality and political stability. This session also features contributions of general interest within the ERE community, which are not covered by other ERE sessions. Aim of this session is to provide an overview of topics within the ERE domain, in particular for colleagues affiliated mainly with other divisions, who are interested in topics within ERE.

The European Green Deal sets an ambitious vision for a climate-neutral Europe by 2050, requiring a fundamental transformation of energy systems and the phasing out of fossil fuels. As part of this transition, coal-dependent regions face profound industrial, economic, and social challenges. This session focuses on the scientific, technological, and socio-economic research needed to support the just transition of coal and lignite regions, ensuring environmental restoration, economic revitalization, and social equity.

The aim of this session is to showcase innovative research that repurposes former mining sites, mitigates environmental legacies, and empowers communities through sustainable development. It will serve as a platform for interdisciplinary dialogue among geoscientists, engineers, environmental researchers, social scientists, and policymakers working to transform former coal regions into hubs of green innovation. Papers are invited that particularly address the objectives of closure, remediation, and sustainable redevelopment of coal mines and associated infrastructure.

Relevant topics include but are not limited to:
• Adaptive reuse of coal mines and related infrastructure (e.g., power plants, shafts, rail networks) for energy storage, district heating, or industrial parks.
• Environmental restoration of post-mining landscapes, including water table protection, mine drainage treatment, and biodiversity recovery.
• Ground stability monitoring and subsidence risk management in former mining areas.
• Mitigation of greenhouse gas emissions, particularly methane, from abandoned and closing coal mines.
• Innovative development of advanced materials from mining waste and tailings, emphasizing their applications in construction, energy storage, and environmental remediation.

• Development and testing of carbon dioxide capture, utilization, and storage (CCUS) technologies in former coal regions.
• Exploration and implementation of geothermal energy systems on repurposed coal mine sites.

The purpose of this session is to present recent advances in the analysis of environmental contaminations using Applied Geophysics, Remote Sensing and Artificial Intelligence approaches.
Characterizing and understanding the surface and subsurface is a challenge for many scientific areas.
The risk assessment of a contaminated place, using traditional procedures, implies soil and water sampling to proceed to chemical analysis to quantify heavy metals. This is very expensive and time-consuming task.
Remote sensing methods can be applied as previous steps of the traditional approaches to define places to create classification maps, to know where the most contaminated sites are.
Applied Geophysics investigates underground using a variety of non-invasive and non-destructive techniques such as ground-penetrating radar, magnetics, electrical resistivity tomography, electromagnetic induction, and seismics. Remote Sensing uses methods such as photogrammetry, LIDAR, GNSS, and satellite hyperspectral data to determine physical properties at a distance. Some Remote Sensing technologies can also give information from the subsurface or the interior of structures. Artificial Intelligence can be a useful tool to manage information using as inputs data provided by different methods that can help in the calculation of contamination maps.
Knowledge in these fields can be applied to a variety of research topics, combining all-together results of several fields like the mentioned above, using Artificial Intelligence. This can enable the development of integrated tools for optimized environmental management, enabling the automated identification of risk areas and promoting the reduction of sampling and operational costs, as well as reducing assessment times in the management of contaminated areas.
This approach has great potential for replication to other contamination problems, such as those produced by industrial waste, landfills, as well as intensive agriculture.
This session will collect the contributions from Applied Geophysics, Remote Sensing and Artificial Intelligence in the following topics:
- Environmental studies: characterization of the soil and water contamination by heavy metals in mining places, industrial waste, landfills and intensive agriculture.
- Innovations in data acquisition, processing approaches, and big data management of Geophysical, Remote Sensing and AI methods.

Energy system modeling and integrated assessment approaches are essential tools for understanding and optimizing the complex interactions within modern energy systems. By simulating these interactions, stakeholders can make informed decisions that improve energy security, support economic viability, social prosperity, and minimise environmental impact.

This session will explore the role of energy system modelling and integrated assessment in advancing sustainable energy transitions, with a particular focus on the impacts of system retrofitting and the integration of renewable sources such as solar, hydrogen, wind, hydroelectric power, and geothermal energy. We will examine hydrogen's growing importance in achieving net-zero emissions, exploring its potential in energy storage, transportation, and industrial applications, as well as its integration with other renewable sources, small-scale energy generation technologies, and advanced grid management systems. In addition, the session will address the social and environmental effects, trade-offs, and co-benefits of renewable energy systems, particularly their impact on communities, job creation, land use and related ecological consequences. Thereby, look at strategies for sustainable planning and management that enhance the environmental and social co-benefits of the renewable energy transition, such as improving community resilience and job creation, as well as ecosystem service enhancement and the mitigation of land use conflicts.

This session aims to bring together researchers from diverse fields, who will discuss how these models and tools can improve decision-making, enable informed policy development, promote interdisciplinary collaboration, and advance broader sustainability goals.

The extraction and processing of mineral resources, whether from oil sands, coal, or metal mines, generate large volumes of mine wastes, including fluid tailings, waste rock, and other by-products that pose long-term environmental challenges. In the case of oil sands, fluid tailings are comprised of processed water, sand, silt, clay, and residual constituents such as bitumen, diluent, and sulfide minerals like pyrite. In metal and coal mining, tailings may contain finely ground rock, processing chemicals, and trace metals, all of which require thoughtful management to prevent environmental degradation. Given their scale and complexity, mine waste deposits are expected to comprise significant portions of closure landscapes worldwide, and returning these sites to stable, sustainable ecosystems remain one of the most pressing challenges faced by industry, regulators, and society.
Reclamation goals across mining sectors focus on reconstructing functioning landscapes that support ecological, hydrological, and geotechnical stability. Achieving success depends on advances in material characterization, landform design, soil cover development, water management, and reclamation practices. Material characterization of tailings and waste rock is central to this process, as it informs the design of soil covers, the selection of plant communities, and the prediction of long-term performance. The reclamation of consolidated tailings and mine wastes is a relatively new and evolving field of research that requires innovative approaches and interdisciplinary collaboration among soil scientists, geologists, engineers, hydrologists, and ecologists.
This session aims to highlight the latest research and practical advances in tailings and mine waste characterization, landform construction, and reclamation strategies across a range of mining contexts. By sharing insights from oil sands, metal mining, and other sectors, we hope to build broader awareness of the challenges and opportunities associated with post-mining landscapes. Ultimately, the goal is to ensure that reclamation efforts deliver functional, resilient soils and ecosystems that will endure for future generations.

Mining is a process of extracting mineral resources from the deposit sites or layers that usually exist in or within the surface of the Earth. Mining activities not only benefit human society but also lead to series of negative influence on natural environment where humans depend on for survival. Especially, after mine closure, mining-induced disturbances and damages as well as risks to surrounding environment still exist. Further deterioration may occur, such as the continuous surface subsidence, the potential slides of slopes, the collapse and falling incidents, the coal spontaneous combustion, the pollution to air, the contamination to soil and water, and the death due to gas suffocation.
Post-mining is an interdisciplinary topic which refers to different disciplines, such as mining, geology, geography, geophysics, geochemistry, mechanics, environment sciences, ecology, management science, economics, which shows different aspects of the engineering and the science. In order to deal with this interdisciplinary multi-aspects and multi-scales mining-induced geo-environmental and eco-environmental issues, the Convener suggests this session which aims to provide a platform for researchers to illustrate their latest research achievements on these topic. Scopes for this session were listed as follow:
• Mining-induced surface subsidence and sliding
• Mining-induced soil contamination and remediation
• Mining-induced water contamination and remediation
• Mining-induced air pollution and prevention
• Utilization of land and ground space at post-mining sites
• Reclamation at post-mining sites
• Strategies for control of post-mining issues
• Others

Geodynamic and tectonic processes interacting across scales are the key engines in shaping the structural, thermal and petrological configuration of the crust and lithosphere. They constantly modify the thermal, hydraulic and mechanical rock properties, ultimately leading to a heterogenous endowment of (often co-located) subsurface resources.
Supporting the transition to sustainable low-carbon economies at scale poses significant challenges and opportunities for the global geoscience community. Improved integration and tighter interdisciplinary understanding of the subsurface processes that can provide access to alternative energy supplies and critical raw materials is needed, as are unifying science-backed exploration strategies and resource assessment workflows.
This session aims to improve our scientific understanding of the pathways and interdependencies that lead to the concentration of economic quantities of energy carriers or noble gases, mineral resources, and the formation of exploitable geothermal reservoirs. Further, it also focuses on providing input for exploration decision-making and scientific input for policy making as well as for the strategic planning of collaborative research initiatives.
We invite studies on observational data analysis, instrumentation, numerical modeling, laboratory experiments, and geological engineering, with an emphasis on integrated approaches/datasets which address the geological history of such systems as well as their spatial characteristics for sub-topics such as:
- Geothermal systems: key challenges in successfully exploiting geothermal energy are related to observational gaps in lithological heterogeneities and tectonic (fault) structures and sweet-spotting zones of sufficient permeability for fluid extraction.
- Geological (white/natural) hydrogen (H2) and helium (He) resources: potential of source rocks, conversion kinetics, migration and possible accumulation processes through geological time, along with detection, characterisation, and quantification of sources, fluxes, shallow subsurface interactions and surface leakage.
- Ore deposits: To meet the global continued demand for metal resources, new methods are required to discover new ore deposits and assess the spatio-temporal and geodynamic characteristics of favourable conditions to generate metallogenic deposits, transport pathways, and host sequences.

This session examines pathways to “real zero” – fully eliminating greenhouse gas emissions from fossil fuels across the energy system and from other key sectors, rather than relying on carbon capture and storage (CCS) or carbon dioxide removal (CDR) to compensate for continued emissions, as is the case in common “net zero” framings. We invite both integrated and sectoral studies that assess the technical, financial, and social implications of pathways to real zero.

We welcome deep dives into sectors such as steel, shipping, aviation, fertilizers, and chemicals, combining empirical evidence with scenario analysis of real-zero options including process change, deep electrification, fuel switching, efficiency, circularity, and demand reduction. Submissions may compare net zero and real zero pathways across a range of relevant dimensions, quantify residual emissions, assess costs and permanence risks, and examine land, resource, and broader sustainability constraints.

We encourage work that clarifies definitions, strengthens accounting and reporting for long-term strategies (LTS), tackles feasibility concerns, and proposes safeguards against over-reliance on CCS and CDR. Analyses that address equity, including distributional impacts, just transition for workers and communities, and fair allocation of residuals and resources, are especially welcome.

The urgency, complexity, and economic implications of greenhouse gas (GHG) emission reductions demand strategic investments in science-based information for planning, implementing, and tracking emission reduction policies and actions. An increasing number of applications succeed by combining activity-based emissions data with atmospheric GHG measurements and analyses – this hybrid approach can yield additional insights and practical information to support mitigation efforts at different scales. Inspired by this potential, the Integrated Global Greenhouse Gas Information System (IG3IS) of the World Meteorological Organization works to identify and document good practice guidelines for informing decisions, while promoting scientific advances and facilitating two-way linkages between practitioners and stakeholders in the policy realm, tailoring research actions to meet policy needs.
Since EGU18, this session continues to showcase how scientific data and analyses can be transformed into actionable information services and successful climate solutions for a wide range of user-communities. Actionable information results from data with the required spatial and temporal granularity and compositional details able to explicitly target, attribute and track GHG emissions and reductions where climate action is achievable.
This session seeks contributions from researchers, inventory compilers, government decision and policy makers, non-government and private sector service providers that show the use and impact of science-based methods for detecting, quantifying, tracking GHG emissions and the resulting climate mitigation. We especially welcome presentations of work guided by IG3IS good practice research guidelines at urban and national scale and for specific economic sectors. The scope of the session spans measurements of all GHGs and from all tiers of observation.

The global transition towards sustainable energy and green technology is reliant on critical resources -- such as geothermal energy sources and mineral deposits. To maintain and accelerate progress, we require an improved understanding of: (i) how and where these resources arise; (ii) techniques to identify, characterise and constrain prospective locations; and (iii) strategies for effective, sustainable and low-impact resource development. Addressing any of these questions requires advances in our ability to simulate a wide range of geological processes, and in our capacity to generate actionable insights from these models in combination with complex, uncertain observational datasets.

This session focusses on the computational and methodological developments necessary for progress towards more sustainable energy. We welcome submissions that address a diverse range of topics -- including simulation e.g. of themo-chemical flow processes, subsurface imaging, data fusion and AI -- with their application to critical resources as a unifying theme.

Critical raw materials, geothermal energy, hydrogen storage, and carbon capture and storage (CCS) all play a vital role in the energy transition and in securing Europe's strategic resources. Exploration and monitoring of these resources and infrastructures require affordable, reliable, and scalable geophysical methods to reduce subsurface uncertainty, de-risk drilling, and ensure safe and sustainable operation.

In recent years, passive seismic imaging has emerged as a cost-effective exploration tool, particularly valuable in complex geological settings and at depths beyond the reach of conventional active methods. These approaches are increasingly demonstrating their potential not only for geothermal and subsurface storage applications, but also for mining exploration.

This session invites contributions that advance passive seismic methodology and modeling for applications to subsurface imaging, as well as case studies showcasing applications to critical raw material exploration, mining, geothermal energy, hydrogen storage, and CCS. We particularly encourage studies highlighting integration of passive seismic techniques into industrial exploration workflows, and contributions spanning ambient-noise and/or earthquake-based approaches.

Science is not above any socio- and geopolitical issues; rather it is intertwined with them. Societal and geopolitical conditions deeply affect the choices we make about what research to fund, whose knowledge to value, where and with whom to collaborate, and who can attend a conference. As scientists, especially in the Earth and planetary sciences, we cannot ignore the human and environmental consequences of our work. It is especially a present issue in Earth observation, where the majority of the satellites have dual-use operating for both scientific and military purposes. In many cases, scientific tools have facilitated ecocide, exploitation of land and natural resources under neocolonial structures.

While discussing security and safety is crucial during times of conflict, we also need to be aware of possible risks that securitisation poses on the ethical, social and environmental aspects of scientific work. This is also relevant for disaster and risk management and preparedness which many geoscientists are involved in.

This session invites presentations by individuals and teams that address questions like:

- How should geoscientists conduct research and collaboration in fragile or geopolitically unstable regions?
- How do geopolitical tensions or decisions influence geoscience research and collaboration, and what can geoscientists do about it?
- What are the impacts of political borders and decisions on the functioning of the Earth’s systems? How do they affect how geoscientists study the Earth’s systems?
- What are the roles of scientists, academic institutions as well as Earth science societies like EGU in facilitating international collaboration, and supporting academic advocacy and activism in times of geopolitical instability and tensions?
- What responsibilities do Earth and planetary scientists carry when their research is used to harm people and the environment?
- What other geoethical dilemmas arise in such circumstances, and how can they be resolved?

Examples may include current or past case studies of Earth science research that has:

- prevented or caused situations that escalated into conflicts
- increased transparency about the impact of war on people and places (e.g., InSAR monitoring of building damage)
- historical and current examples of geoscientific knowledge used for resource extraction, such as hydrocarbon, water and critical minerals, and their links to conflict, instability, forced migration, famines and underdevelopment

Geoscientists play a key role in providing essential information for decision-making processes that consider environmental, social, and economic consequences. Therefore, their responsibilities go beyond scientific analysis. Global challenges such as climate change, resource management, and disaster risk reduction urge geoscientists to extend their role beyond research and ethically engage in public efforts. Geoethics provides a framework to reflect on the ethical, social, and cultural implications of geoscience in both research and practice, guiding responsible action for society and the environment. It also encourages the scientific community to move beyond purely technical solutions, embracing just, inclusive, and transformative approaches to socio-environmental issues.
This session aims to explore, through case studies and discussion, how geoethics can shape responsible behaviors and policies in geosciences. We welcome theoretical, methodological, and practical contributions addressing a wide spectrum of issues, such as:
• Ethical and social aspects in geosciences, at the interface between geosciences, society, politics, and decision-making processes
• Responsible and sustainable management of georesources (surface and groundwater, soil, rocks, minerals, and energy)
• Ethical and social aspects in geo/environmental education and geoscience communication
• Geoethics in natural hazards, georisks, and disaster reduction
• Ethical and social relevance of geoheritage, geodiversity, geo-conservation, geotourism, and geoparks
• The role of geosciences in achieving the United Nations Sustainable Development Goals
• Ethical and social issues related to climate change
• Ethical aspects in new geoscience frontiers (such as geoengineering and deep-sea mining)
• Ethical implications in data lifecycle management, big data, and the use of AI in geosciences
• Ethical questions across various geoscience disciplines, including economic geology, engineering geology, hydrogeology, paleontology, forensic geology, medical geology, and planetary geosciences
• Integrity in research and practice in geosciences, publication ethics, and professionalism
• Issues of inclusivity, diversity, harassment, discrimination, and disability in geosciences
• Incorporating Indigenous and local knowledge into geosciences
• Geoscience neo-colonialism
• Ethical and social issues in international geoscience cooperation
• Philosophy of geosciences and the history of geoscientific thought

We invite contributions on all aspects of Meteorology and Climate for Renewable Energy (RE):
• Energy: wind, solar, hydro, tidal, wave, geothermal etc
• Spatial: microscale, mesoscale, synoptic and global
• Temporal: seconds, minutes, diurnal, seasonal, interannual, decadal and climatological
• Approach: measurement, modeling
The success of wind power has pushed turbines and research need into increasingly complex environments — mountainous terrain, forested areas, high in boundary layer and offshore. For solar power, new installation sites such as floating PV both rivers, water reservoirs for artificial snow, and “alpine PV farms” are gaining more attention. We need accurate measurements and short-term forecasts of cloud fields and aerosol effects. For weather-dependent renewables, the challenge of integrating shares into the power grid requires advances in understanding forecast uncertainty and spatio-temporal variability. Furthermore, meteorological conditions define how much power can be sent through the power grid and could help prevent curtailment or negative energy pricing.
Specifically, we invite contributions including but not limited to:
• Measurement techniques and analysis for e.g., wind, solar, hydro, and marine resources.
• Wind conditions (resource, extremes, turbulence) on all scales in complex environments (mountains, forests, coastal, offshore, urban).
• Wake effect models and measurements
• Forecast performance and uncertainty of RE at different time horizons
• Forecasts and detection of extreme and adverse weather events (wind ramps, droughts, heatwaves, storms, compound and consecutive)
• Detection and forecasting of dynamic line rating suitable conditions
• RE resource and atlas development (wind, solar, hydro, wave, thermal)
• Hydro-meteorological analyses of inflow variability, snowpack, precipitation extremes, and their implications for hydropower
• Tidal and wave resource assessment and predictability
• Impacts of renewable power plants or their large-scale integration on local, regional, and global scales
• Tools for strategic planning of RE in urban areas and smart energy systems.
• Climate Change Impact studies for renewables and weather-driven energy demand
• Interannual to decadal variability of renewable resources
• Typical Meteorological Years and probability of exceedance metrics
• AI and Machine Learning for weather and climate forecasting and applications to RE

Reliable, affordable and climate‑resilient energy and infrastructure systems are pivotal for the achievement of sustainable development goals in the Global South. However, their design relies on skilful weather forecasts and climate projections in regions with sparse observations and poorly constrained models, where climate change is driving rapidly changing extremes. This leads to large uncertainty in pathways to net-zero, which will be explored in this session through the broad context of inviting contributions that:
1) assess climate‑impact drivers across sectors – wind, solar, hydro and bioenergy resources; drought, heatwaves, dust and tropical cyclones affecting energy, agriculture, water and health;
2) develop forecasting and scenario tools – these may include subseasonal‑to‑seasonal prediction of climate extremes and demand, nowcasting for micro‑grids or wind farms, storyline-based or multi‑decadal outlooks for planning and integration with power‑system, agricultural and hydrological models;
3) co‑produce climate services – e.g., through integration of citizen science, social science, AI/machine‑learning approaches to tackle data scarcity, ethical considerations, and design of equitable services with local utilities, communities, researchers and policymakers;
4) develop open data/open‑source models and training programmes to empower researchers and practitioners in the Global South; and
5) quantify socio‑economic impacts, cost analysis and policy pathways towards just and resilient energy systems.
We encourage case studies led by scientists and practitioners from Low- and Middle-Income Countries and abstracts demonstrating innovative methodologies and interdisciplinarity across engineering, economics, social sciences and weather and climate science. The session hopes to build a network that supports climate‑resilient development and progress towards Sustainable Development Goal 7.

This session addresses spatial and temporal modelling of renewable energy systems, both in a prospective as well as in a retrospective manner. Therefore, contributions which model the characteristics of future renewable energy systems are equally welcome as contributions assessing the characteristics of the past performance of renewable energies. Session contributions may reach from assessments of climate data based simulations of renewable generation, over assessments of land use implications of renewables, to economic assessments linked to spatial and temporal variability of renewables and full energy system model studies applied to understand energy systems with high shares of renewables.

Studies may for instance:
Show the spatial and temporal variability of renewable energy sources, including resource droughts and complementarity between technologies and locations.
Assess the resilience of energy systems to weather and climate extreme events, with a focus on infrastructure and resource adequacy, and analyze economic incentives to ensure reliable energy systems under current regulatory, market and tariff conditions.
Derive scenarios for the spatial allocation of renewable energies based on climatic, technical, economic, or social criteria.
Assess past spatial deployment patterns of renewables.
Assess past impacts on land cover and land-use, including impacts on biodiversity and other environmental indicators
Explore and quantify impacts of wind and solar power deployment on the social and natural environment in a spatially explicit way, including economic valuations of such impacts
Derive integrated scenarios of energy systems with high shares of renewables (Including systems from the local scale, e.g. in form of local Energy Communities, to the national or continental scale).

The objective of the session is to provide an insight into recent advances in the field of renewable energy system modeling. The session welcomes research dedicated to climatic and technical issues, assessments of environmental impacts, economic analysis of markets, policies and regulations, and forecasting applications , concerning renewable energy systems.

The global transition towards “Net zero” requires rapid and sustained decarbonization across multiple sectors, with the electricity sector playing a key role over the coming decades. On the supply side, renewable energy resources exhibit variability across multiple timescales, from minutes to seasons to interannual. Climate change is expected to alter not only the mean patterns of renewable resources but also their variability and the possibility of disruptive extreme events. On the demand side, extreme weather and climate change will shape both overall consumption and peak load. Unmanaged demand growth pathways can raise mitigation costs, intensify pressure on renewable resources, and exacerbate policy tradeoffs, while demand-side management can balance volatile renewable supply.
Considerable uncertainty remains in projecting long-term spatio-temporal changes in renewable sources, demand and low probability extremes that can disrupt the energy system. Since demand must be balanced by generation from largely renewable sources, there is an urgent need for deeper dialogue between climate science, climate risk, and energy transition research communities.
This session invites contributions spanning pathways to accelerate renewable energy transitions under climate change; approaches to just and equitable energy transitions; insights from climate modeling for demand or supply side challenges; approaches for balancing renewable generation with demand management across timescales; innovative concepts or tools to address uncertainty in energy-climate interactions; insights how climate risks impacts the energy transition. We encourage model-based, empirical, and conceptual studies alike, incluing:
* Impacts of climate variability (including extremes) and change on energy systems, and associated uncertainties
* Effects of present and projected renewable resource variability on energy systems, and technical approaches to balance supply and demand
* Climate-related drivers of energy demand, and the role of demand reduction and management in supporting low-carbon transitions
* Influences of extreme events and spatio-temporal complementarities on both demand and supply within energy systems
* Integrated assessments combining supply and demand side approaches to low-carbon transitions
* Spatio-temporal data needs from climate science and modelling to advance understanding of renewable energy supply and demand under climate change

Geothermal energy emerges as a critical component of the urban energy transition, offering constant base-load energy supply, minimal land requirement, and integration into multicomponent energy networks. This session explores the scientific, engineering, and strategic foundations necessary to unlock the potential of geothermal energy in urban settings.
We invite contributions across the spectrum of geothermal technologies: hydrothermal, petrothermal, closed-loop, enhanced geothermal systems (EGS), and aquifer or borehole thermal energy storage (ATES/BTES). Reliable forecasting and sustainable geothermal utilization require solid understanding of the subsurface structure and physical properties. Integrated exploration strategies—seismic, geological, and geophysical studies—combined with consistent monitoring during operation is vital for optimal reservoir management and for minimizing environmental impacts.
The session further addresses the complex interaction between reservoir heterogeneity, imposed perturbations by operation, and impact on governing physical processes. These coupled mechanisms may cause stress redistribution or rock deformation and—in faulted/fractured reservoirs or EGS projects—enhance the seismic risk. Understanding the coupled thermal-hydraulic-mechanical-chemical (THMC) response of geothermal systems is thus crucial for predictive analyses, sustainable operation, and risk mitigation. Contributions on predicting and mitigating induced seismicity, including risk management approaches such as traffic light systems, are especially encouraged.
To this end, we welcome diverse methodological approaches: analytical studies, laboratory and field experiments, multiphysics numerical modeling, and data-driven or machine learning approaches resolving the relevant physical mechanisms across spatial and temporal scales. Case studies and operating geothermal projects highlighting engineering challenges (e.g. wellbore stability, scaling), successful methodologies and engineering solutions, or novel geothermal concepts are especially valuable.
Beyond engineering innovation, the session addresses the broader context of geothermal deployment in urban environments. We invite contributions on management strategies of the geothermal resource and integration into urban energy planning. By showcasing innovative research and practical applications, this session highlights the multifaceted potential of geothermal energy in advancing the urban energy transition.

The transition toward renewable and sustainable energy systems requires efficient, cost-effective, and digitally integrated approaches to geothermal energy exploration, development, and monitoring. As Europe and the world accelerate the energy transition, digital technologies are becoming central to unlocking geothermal’s potential as a reliable and local energy source.
This session invites contributions on the role of data, databases, and data science in geothermal energy across the full lifecycle—from site characterization and exploration, to reservoir engineering, monitoring, and operational optimization. We welcome technical and interdisciplinary perspectives on how structured data, machine learning, artificial intelligence, statistical models, and GIS-based systems are transforming the geothermal field. Submissions on open-access data platforms, standardization initiatives, FAIR data principles, semantic web technologies, and cross-border data harmonization are particularly encouraged. Building on earlier efforts (e.g., GeoERA, DESTRESS, HeatStore, Geothermal-DHC), recent and ongoing projects such as GSEU, MALEG, GeoMAP are advancing geothermal data infrastructures and fostering international collaboration. National initiatives like WärmeGut further demonstrate the importance of coordinated efforts at both European and national scales.

Key topics include:
• Development and use of geothermal databases (e.g., GeotIS, EGDI, PanGeo)
• Data quality, uncertainty quantification, and metadata standards
• Integration of multi-source datasets (geophysical, geological, thermal, chemical, operational)
• AI/ML applications in targeting, reservoir modelling, or failure prediction
• Digital workflows: remote sensing, big data, and automation Digital twins, real-time monitoring, and operational optimization
We welcome contributions from research institutions, industry practitioners, data infrastructure providers, and policymakers. The session aims to foster collaboration between geoscientists, data scientists, and system developers, and to support the broader digital transformation of the geothermal sector.

This session focuses on establishing an inventory of geoscience technologies (e.g., data acquisition methods, characterisation approaches, static and dynamic modelling techniques) and societal approaches during the exploration and appraisal of geothermal projects. The goal of this session is to enable cross-disciplinary knowledge sharing that helps to improve our understanding of geothermal resources across different geological settings, reduce exploration risks, and ensure the safe and sustainable exploitation of this energy source. A collaborative, transdisciplinary, and collegial discussion will be crucial to accelerating geothermal project deployment in Europe and beyond.
We welcome interdisciplinary contributions from the fields of geology, geophysics, geochemistry, geomechanics, hydrogeology, machine learning, and static and dynamic geomodelling, including case studies from different geological settings such as sedimentary aquifers, volcanic systems, or fractured basements.

As renewable energy penetration grows, the variability and uncertainty of weather are becoming first-order drivers of electricity grid reliability and energy market volatility. Prolonged wind lulls, sudden cloudiness, jellyfish affecting the cooling of nuclear power plants, or compound multi-hazard events can challenge both short-term operations and long-term planning. Traditional deterministic planning and rule-of-thumb margins are no longer sufficient, especially as energy systems become more localised and spatially heterogeneous. Advanced probabilistic and high-resolution approaches are needed to quantify risk, guide investment, and design resilient energy systems.

This session focuses on probabilistic methods that bridge geoscience and power-system analysis, leveraging atmospheric and hydrological data, statistical extreme value theory, and modern machine learning to improve decision-making in renewable-dominated systems. We welcome contributions that advance this interface through
- Probabilistic resource adequacy and extremes, including methods for Loss of Load Expectation (LOLE), Expected Energy Not Served (EENS), Effective Load Carrying Capability (ELCC), compounding weather-driven events, energy-hub design and structural congestion studies.
- Spatio-temporal probabilistic forecasting, including ensemble methods, post-processing, generative models, and calibration of prediction intervals to support operational flexibility and reserve management.
- Geostatistics and data fusion, including combined satellite products, reanalysis data, combined spatial- and point-based observations, and the propagation of weather uncertainty to energy system operation and planning.
- Open tools and reproducibility, including frameworks like PyPSA, Calliope, open datasets and standardised benchmarks.
The goal of this session is to foster a shared methodological language for risk-aware planning and operation, connecting geoscientists, energy researchers, and practitioners to advance probabilistic methods for the energy transition.

Hydropower is a mature and cost-competitive renewable energy source, which helps stabilize fluctuations between energy demand and supply. The structural and operational differences between hydropower systems and renewable energy farms may require changes in the way hydropower facilities operate to provide balancing, reserves or energy storage. Yet, non-power constraints on hydropower systems, such as water supply, flood control, conservation, recreation, navigation may affect the ability of hydropower to adjust and support the integration of renewables. Holistic approaches that may span a range of spatial and temporal scales are needed to evaluate hydropower opportunities and support a successful integration maintaining a resilient and reliable power grid. In particular, there is a need to better understand and predict spatio-temporal dynamics between climate, hydrology, and power systems.

This session solicits academics and practitioners contributions that explore the use of hydropower and storage technologies to support the transition to low-carbon electricity systems. We specifically encourage interdisciplinary teams of hydrologists, meteorologists, ecologist, power system engineers, and economists to present on case studies and discuss collaboration with environmental and energy policymakers.

Questions of interest include:

- Prediction of water availability and storage capabilities for hydropower production

- Prediction and quantification of the space-time dependences and the positive/negative feedbacks between wind/solar energies, water cycle and hydropower

- Energy, land use and water supply interactions during transitions

- Policy requirements or climate strategies needed to manage and mitigate risks in the transition

Storing energy (e.g., hydrogen, ammonia, heat) and carbon dioxide within underground stores such as porous media reservoirs and engineered caverns is crucial for enabling the shift toward a carbon-neutral economy built on renewable-based power and heat systems. The suitability of subsurface storage sites depends on hydromechanical properties of the reservoir and its confining units, and integrity of seals due to induced thermal, mechanical, hydraulic and chemical changes. Secure subsurface storage, together with public acceptance in essential technologies, demand geological expertise, continuous monitoring, and careful assessment of potential risks.
This session offers a platform for interdisciplinary scientific exchanges between different branches of storage expertise, and aims to address challenges concerning the storage of fluids in geological reservoirs from core- to field-scale. Contributions are encouraged that include analytical studies, laboratory experiments, computational simulations and field-scale testing to advance insight into the coupled physical and chemical processes involved in subsurface storage. Case studies and operational projects integrating different elements of the storage chain, as well as field projects focusing on geological energy/carbon storage, are particularly welcome.
Relevant topics include:
• Regional and local characterization of storage formations, including their short- and long-term physical and chemical behaviour during the storage operations
• Evaluation of existing infrastructure and fluid injection strategies for effective subsurface storage
• Numerical modelling of migration, containment, geochemical and microbial reactions of injected fluids
• Geophysical, geomechanical and geochemical monitoring and measurements for safe and cost-effective storage

• Evaluation of caprock and fault stability and wellbore integrity, and associated leakage potential and induced seismicity

Geoscientific knowledge is essential to assess safety requirements for radioactive waste disposal strategies. Safety requirements include i) isolation of the nuclear waste from humans and the accessible biosphere, ii) containment of radionuclides by retention and retardation, iii) limitation of water inflow to the geo-engineered facility and iv) long-term geological stability of the site.

The session covers all waste disposal designs, from (near-)surface over shallow to deep geological repositories. Key topics included in this session are:
• Role of geosciences in site characterisation and selection process
• Features and evolution of natural and engineered barrier systems, including induced effects
• Bio-geo-chemical processes, both natural and repository-induced
• Geoscientific evidence supporting Performance and Safety Assessment
• Long-term evolution studies of interactions among hydro-, geo- and bio-sphere, and their impact on the disposal system
• Radionuclide migration assessment
• Impact of short-term and long-term climate change on waste disposal facilities

Contributions on the above topics can include all aspects covering lab-scale experiments, large-scale investigations in underground research laboratories, information from site characterisation campaigns, studies of natural analogues, data management, review studies, and development and application of digital tools.

The successful implementation of safe deep geological disposal of nuclear waste and other long-lived waste is one of the important environmental challenges in several countries worldwide. Site investigation and selection are primarily geoscientific tasks that require collaboration of different disciplines, like geophysics, hydrogeology, geochemistry, mineralogy, geomechanics, material science, and geological as well as THMC modelling. The development of DGRs also involves the integration of technical designs, evolving regulatory frameworks, and social acceptance considerations.

Barrier integrity is a crucial aspect for the assessment of nuclear waste disposal. Numerical simulations, in conjunction with experimental studies are an integral part of safety and environmental-impact assessment. Reliable comparative analyses of potential technological options require coupled THMC models capturing the particularities of each rock type and associated repository concept. Structural as well as process complexity are met by data scarcity and variability, necessitating the treatment of uncertainties and variability. The session provides a platform for the exchange on the following topics:
- THMC characterization of materials in natural or engineered barriers in lab- or field-scale experiments
- Hydro-mechanical behaviour of materials with extreme hydraulic properties (e.g. low permeability, high suction) and ranging from ductile viscopolastic salt rocks to quasibrittle fractured rock masses
- Hydraulic and chemical behaviour of geologic and geotechnical barriers
- Computational methods, models and uncertainty quantification for barrier integrity assessment in multi-barrier systems
- Geotechnical aspects of repository construction, operation, and post-closure, e.g. monitoring methods, excavation and support, retrieval/recovery, etc.
- Minimally invasive characterization of geology and underground installations using geophysical and geohydrological methods

Contributions can include lab-scale experimentation, underground research laboratories, observation of natural analogues, physics- and data-driven modelling and code development.
Furthermore, the session invites contributions addressing regulatory challenges, public outreach programs, lessons learned from national and international DGR projects, the need for transparent communication to ensure public confidence, and the relevance of geoscientific fundamentals in ensuring the safety of nuclear waste disposal.

This session showcases the opportunities and challenges around multi-uses of the subsurface. It seeks to present work from any discipline or methodological background which is concerned with deepening our understanding of how the subsurface can contribute to a low-carbon, fair, future in a sustainable way. This inherently involves the consideration of the subsurface as a spatial and temporal space where multiple uses are possible, for example, energy storage, carbon dioxide removal, geothermal energy production, urban infrastructure or production of drinking water.

This session explores the relationship between these uses, how they change and interact with the subsurface resources (e.g. void space, heat, water) through space and time, and whether they are compatible, incompatible or synergistic. Mechanistic modelling, techno-economic as well as life cycle assessment, screening, characterisation, design, business models, case studies, environmental impact assessment and more are required to understand this critical topic in ensuring uses of the subsurface that are sustainable and mindful of current and future needs.

This session will bring together geosciences, engineering, legal, economic, environmental and social perspectives, it highlights methods, tools and governance frameworks to identify synergies, resolve conflicts and ensure long-term, sustainable use of geological resources.

Thermal Energy Storage (TES) is a key component for an efficient energy supply and for achieving a low-carbon energy balance. TES allows flexible storage volumes and periods, and it represents a cross-sector technology as it couples heat, cooling energy, and electricity. This session is dedicated to Underground Thermal Energy Storage (UTES) technologies, their performance and engineering, as well as new insights into related heat transport processes in the subsurface. In particular, the focus is on Aquifer Thermal Energy Storage (ATES), Borehole Thermal Energy Storage (BTES), Mine Thermal Energy Storage (MTES) and related ground-based variants such as pit storage, cavern storage and artificial water-gravel storage basins. The aim of this session is to overcome technical obstacles concerning the design and sustainable operation of TES. We want to improve our understanding of any UTES-related thermal, hydraulic and other environmental effects.
In a broader context, we invite contributions that show how to enhance the societal perceptions and engagement in UTES developments and how to integrate UTES technologies in wider energy system. Both in research and in practice, accurate characterization of subsurface flow and heat transport based on observations of induced or natural variations of the thermal regime is essential. Thus, we invite contributions that reveal new insight into advances in experimental design, report novel field observations, as well as demonstrate new sequential or coupled modelling concepts. The seasonal and long-term development of thermal and mechanical conditions in aquifers and heat transfer across aquifer boundaries are focus points. This also includes the role of groundwater and geothermal energy in the context of UTES for predicting the long-term performance of storage and production of thermal energy (heating and cooling), as well as integration into urban planning and policy making. We also invite hydrogeological studies that examine heat as a natural or anthropogenic tracer with the aim of enhancing thermal response testing or improving our understanding of relevant transport processes in the underground.

Large-scale deployment of underground fluid and energy storage technologies, ranging ‎from CO2 and hydrogen to geothermal energy storage, and deep waste containment, is ‎crucial for a sustainable and climate-resilient future. Achieving safe, efficient, and ‎cost-effective operations at scale requires advancing both our process understanding ‎and our ability to forecast subsurface system behavior under diverse geological and ‎operational conditions. This session welcomes studies that explore knowledge, ‎workflows, and tools to extend pilot or early-stage commercial projects to regional ‎deployment, acknowledging cross-disciplinary approaches that integrate physico-‎chemical insights, engineering design, monitoring strategies, and predictive models. ‎We especially encourage contributions that combine multiscale experimentation under ‎heavily monitored conditions, from core-scale to underground rock laboratories and ‎demonstration projects, with computationally efficient, physics-informed, and/or data-‎driven models. Emphasis is placed on strategies that enable real-time decision making ‎and long-term performance evaluations, paving the way for storage at scale. The ‎session aims to highlight advances that translate fundamental understanding into ‎practical, scalable geostorage solutions by addressing key challenges related to storage ‎capacity, integrity, and sustainability. By discussing multiple storage applications, this ‎session seeks to identify transferable methodologies, best-practice guidelines, and a ‎path toward accelerating the safe and effective use of the subsurface for the energy ‎transition and long-term environmental protection.‎

According to IPCC scenarios current development of CO2 emissions have reach a level where climate warming can be mitigated with the support of geologic CO2 storage only. There is an urgent need to store >10 Gigatons CO2 per annum (Gtpa). Geologic storage in saline aquifers and depleted carbon reservoirs requires monitoring to ensure conformance over hundreds of years. Reactive geologic formations provide an alternative by mineralizing CO2 and thus preventing escape. During CO2 storage in basalt complexes, the injected fluid will react with the host rock leading to relatively rapid precipitation of solid and immobile carbonate. Thus, basalt complexes, which occur extensively worldwide, are expected to provide tera-tons of permanent carbon storage volume. However, physical properties, porosity, permeability, reacting minerals, dissolution and precipitation rates need to be investigated in further detail. Analogue laboratory experiments need to inform digital models on the definition of host rock reaction algorithms and parametrization. Laboratory experiments and modeling need to test and establish reactive flow rates, effects of fractures on crystallization and permeability. Physical properties, mineralogic composition, geographic location and other aspects might reduce the economic feasible volume available. While offshore storage avoids conflicts with urban areas and other potential usage demands it might find higher public acceptance. Reasonable reaction rates of the injected carbon and limited monitoring demands might balance higher costs during operation of the deposit site. Investigations and characterization of promising lava flows are required to identify optimal host rocks, economic applications of monitoring strategies (minimizing observation wells), and to evaluate transport and injection processes.
In this session we welcome contributions on all aspects of CO2 sequestration of large volumes of CO2 in basalt complexes. This may cover (and should not be limited to) CO2 transport (on/offshore), selection and characterization of injection sites (host rock specification, stratigraphy, physical parameters, reaction rates), CO2 injection operation, laboratory tests and/or modeling of CO2/host rock interaction, operation of an injection site (plumbing, pressure control), CO2 distribution (modeling, monitoring), mineralization process (modeling, monitoring) and techno-economic studies.

Energy gas geo-storage is crucial for achieving a sustainable future, as it helps to reduce CO2 emissions and facilitates the provision of large-scale renewable energy. However, a persistent gap exists between small-scale theoretical advances and large-scale practical implementation. This session brings together research on geological storage of CO2, hydrogen, natural gas and other fluids across molecular, pore, reservoir and field scales. Contributions will address fundamental mechanisms, innovative experimental and modelling approaches. Particular emphasis will be placed on technologies and strategies to translate laboratory findings to field-scale implementations. By integrating insights across scales, this session aims to explore pathways for advancing geo-storage toward gigaton-scale deployment, thereby supporting energy security and global climate goals.

Fluid-rock interactions of ultramafic rocks in the subsurface have a substantial potential for large-scale CO2 storage by long-term mineralization, are a source of natural H2 resources, and play an important role in the formation of various critical ore deposits (e.g. Ni, Co). Understanding the underlying processes is therefore highly relevant for climate crisis mitigation and the energy transition. The coupled chemical, hydrological and mechanical feedbacks and the interplay between dynamic changes in pH, redox conditions and critical metal mobility during these interactions are not yet fully understood. We cordially invite contributions that advance our understanding of the conditions, mechanisms and rates of CO2 mineralization, H2 generation and element mobility during fluid-rock interactions in peridotites and serpentinites from microscopic to industrial and tectonic scales, including studies of natural analogues, field surveys, pilot injection sites, laboratory experiments and theoretical simulations.

Accurate knowledge and understanding of the subsurface stress state and their variation are crucial for a wide range of topics, from plate tectonics and geohazards to mass transport and engineering applications. Conventional and emerging applications such as geothermal energy, Carbon Capture and Storage (CCS), hydrogen or gas storage or disposal of nuclear waste are pivotal for a low-emission society, with their efficacy heavily reliant on knowledge of the subsurface stress state. The difficulty in determining the stress state and constraining subsurface structures though requires advances in modelling algorithms and inversion methods, as well as the development of concepts, experiments, and new measuring techniques.
This session calls for contributions that showcase novel methodologies and/or ambitious case studies. Topics of interest include, but are not limited to:
- Advances in stress orientation and magnitude estimation
- New methodologies for 3D geomechanical modelling, including deterministic, stochastic, hybrid approaches or stress state visualisations
- Outstanding case studies highlighting crustal stress characterisation, fault stability, and/or the application of geomechanical modelling
- Advances in computational efficiency and uncertainty quantification
- Innovative use of machine learning and AI in enhancing models and approaches
This session brings together geoscientists, modellers, and computational experts from an academic and application background to discuss the latest advancements and challenges, offering insights into the future direction of characterizing the present subsurface stress state.

In a rapidly changing world, the relevance of tectonics and structural geology to societal challenges is more pressing than ever. This session invites abstracts that demonstrate how geological structures and tectonic processes can be harnessed to support the energy transition, mitigate natural hazards, and contribute to sustainable development.
We are particularly interested in studies that examine how tectonic and structural factors influence the safety, feasibility, and long-term sustainability of energy transition technologies. This includes the assessment of tectonic risks associated with geothermal energy development, subsurface energy storage, and carbon capture and storage, especially in seismically active or structurally complex regions. Contributions that explore the role of structural geology in managing critical raw materials, groundwater resources (heat storage), and infrastructure resilience are also welcome. We encourage submissions that integrate fieldwork, geophysical data, numerical modelling, and remote sensing, as well as those that present innovative case studies or cross-sector collaborations.

The growing global resource scarcity along with the criticality of high-tech-relevant raw material, poses immense challenges for the sustainable development of our society. Reducing the environmental footprint of mineral exploration and extraction requires sustainable solutions that are socio-economically viable. In this context, an accurate and effective resource characterization is essential not only for supporting economic resilience but also for mitigating environmental impacts and advancing the transition toward sustainable, semi-circular economic models. Emerging technologies, from autonomous robotic explorers to real-time data analytics, are redefining what is possible in mineral exploration and production. These innovations open opportunities to re-evaluate previously “non-economical” deposits, including abandoned sites, ultra-deep reserves, and small-scale resources, and to optimize recovery processes and footprints.

This session targets innovative tools and methodologies that are redefining raw material exploration and characterization. We emphasize multi-scale, multi-source and multi-disciplinary approaches that integrate advanced sensing, modelling, automation and data-driven solutions. The session focuses in particular on method innovations in the field of remote sensing, geophysics, geochemistry, raw material processing, as well as on recycling processes.

We encourage interdisciplinary studies which use a combination of methods to solve challenges as diverse as, but not limited to:
• Next-generation sensing and imaging: non-destructive techniques, core scanners, and airborne/ground-based sensors for high-resolution, accurate, precise, and efficient resource identification.
• Smart field and analytical approaches: geophysical and geochemical mapping, isotope dating, and novel sampling workflows for multi-scale ore body understanding.
• Digital modelling and simulation: advanced conceptual models and quantification methods for deposits and mineral systems.
• Automation and real-time decision-making: AI-driven, automated data processing that enhances resource management, mining selectivity, and recycling efficiency.
• Information integration and visualization: innovative platforms for merging data streams from diverse sensors to improve accuracy and reduce uncertainty.
• Data-driven discovery: machine learning, geostatistics, data fusion, and computational advances unlocking new insights in mineralogy and geochemistry.

Mine waste is both an escalating environmental and geotechnical risk and a strategic secondary resource. Across billions of tonnes stored in tailings storage facilities (TSFs) and waste-rock dumps (WRDs), as well as other post-mining residues, stability concerns and impacts on water and air quality coexist with recoverable critical raw materials (CRMs). This session brings together researchers, industry, and authorities to advance multi-scale Earth observation (EO) and data-integration workflows for characterisation, operational monitoring, and valorization of mine waste. We welcome contributions spanning different spatial and temporal scales that leverage satellites (optical, hyperspectral, thermal, SAR) and UAVs (photogrammetry, hyperspectral, geophysics), alongside near-surface geophysics and in-situ sensors, addressing a diversity of waste origins (sulfidic, coal and lignite, industrial by-products, legacy sites, active operations).

Key topics of interest include:
(i) Geotechnical aims: stability and deformation monitoring, erosion modelling, water balance, and moisture mapping.
(ii) Environmental aims: water pollution/acid mine drainage, dust and aerosols, vegetation health monitoring, and ecosystem recovery.
(iii) Valorisation aims: re-mining/re-processing case studies that link EO-derived composition/proxies to processing options for secondary CRM recovery.

We particularly encourage interdisciplinary contributions that combine Earth observation with advances in artificial intelligence, database development, and frameworks for circular economy and energy transition. By linking technical monitoring with societal, economic, and policy perspectives, the session aims to advance holistic approaches for managing risks and unlocking the resource potential of mine waste.

The increasing demand for Critical Raw Materials (CRMs), driven by the need to address climate change and meet global needs, is already leading to substantial growth in extractive activities. Ensuring a reliable CRMs supply will require identifying and exploiting new and alternative sources, including CRMs as byproducts of conventional ores and reprocessed extractive waste (EW). Developing smarter, cleaner extraction methodologies for primary and secondary resources will be essential. The extraction of CRMs, from exploration to waste management, has numerous impacts on the environment, including landscape and land use degradation, as well as soil and water contamination, with cascading effects on the biosphere. This results in social and economic challenges and opportunities at various stages of the mining cycle, particularly connected to EW deposits. As a whole, CRM supply must be accompanied by responsible and integrated management throughout the entire value chain.
This session welcomes contributions on the following topics:
- Exploration and extraction of CRMs as primary resources.
- CRM recovery as by-products of common mineral exploitation.
- Revalorization of extractive waste facilities as secondary sources of CRMs.
- Technological innovations for the exploration, extraction, and (re)processing of minerals from primary deposits and EW.
- Technological advancements in sampling and characterization procedures for minerals and EW, aimed at improved resource evaluation and environmental impact assessment.
- Multiscale CRM exploration: innovative sensing technologies, automation, and modeling of primary and secondary resources.
- Environmental aspects of CRM extraction from primary resources.
- Environmental and geotechnical innovations for tackling challenges associated with EW facilities.
- The role of current regulations in driving innovative solutions and fostering responsible production of mined products including the extraction of CRMs.
- Role of economists, social scientists, legal scholars, psychologists, and policymakers in addressing the social and economic challenges of new and reactivated mines to promote a responsible and socially accepted mining sector.
- The role of AI and machine learning across the entire mining life cycle.

As the global energy transition accelerates, there is an increasing need to understand the lithosphere not only for critical minerals, but also for emerging resources such as natural hydrogen and geothermal energy. This session aims to bring together geoscientists—particularly geophysicists working across diverse methodologies—to foster interdisciplinary discussion and advance our understanding of how lithospheric architecture controls the formation, distribution, and preservation of these resource systems.

We invite contributions focused on imaging and characterising the continental lithosphere at scales ranging from regional to local, using geophysical array and profile data. Studies that integrate multiple datasets—such as electromagnetic surveys, magnetotellurics, seismic tomography and reflection, distributed acoustic sensing, gravity, magnetics, geoid, and heat flow—are particularly encouraged. We also welcome research that combines geophysical data with geological, geochemical, mineralogical, and petrophysical approaches to provide a holistic understanding of lithospheric processes.

This session will highlight advances that inform the discovery and sustainable development of critical minerals, natural hydrogen, and geothermal resources, ultimately contributing to a secure and low-carbon energy future.

Pyrite is the most common sulphide in the Earth’s crust and occurs in many different types of rock. Following many decades of research, the morphology, trace element and isotopic composition of pyrite can be used to reconstruct a range of bio- and geological processes across a broad spectrum of scales.
In the oceans, pyrite is the dominant sink for reduced sulphur and is intimately connected to biological pathways of sulphate reduction, meaning the formation and isotopic composition of pyrite can be used to reconstruct the redox architecture of ancient marine environments and constrain carbon burial fluxes. On land, pyrite weathering can be a geologically relevant process leading to carbon release to the atmosphere. As a major gangue mineral phase in hydrothermal ore deposits, the formation and geochemistry of pyrite can be used to investigate and potentially detect ore forming processes. At the other end of the life-cycle, the pyrite oxidation during acid mine drainage and subsurface geological storage is a major environmental concern.
This session encourages contributions from scientists investigating pyrite across a range of physico-bio-geochemical conditions in various earth science disciplines, including but not limited to paleoenvironmental reconstructions, nuclear waste storage, ore deposit formation or acid mine drainage. Our aim is to foster intradisciplinary knowledge transfer between different research areas and approaches, including geochemical field studies, in-situ and laboratory investigations of rocks and formations as well as numerical simulation studies within the given context.

Geochemistry — including chemical and isotopic (e.g., O, H, C, S, Sr, Li, Pb) characterisation of liquid, gaseous and solid phases — is one of the most effective tools for exploring and managing natural resources such as oil, gas and geothermal reservoirs in volcanic and sedimentary basins, critical raw materials, and mineral ore deposits. In addition, geochemistry plays a crucial role in both monitoring and exploration of subsurface hydrogen and carbon storage. By combining natural fluid samples with thermodynamics and experimental studies on water-gas-rock interactions, we can better understand the deep subsurface processes, chemical and isotopic equilibria governing fluid composition under varying pressure-temperature conditions and the distribution, mobilisation, and migration of elements.

The microbial diversity in the Earth’s subsurface — including bacteria, archaea, and fungi — also influences the chemistry of fluids and may control the motion, stability and availability of many raw elements and chemicals commonly used as tracers for natural resources. Moreover, microbial reactions can control the accumulation and release of many compounds, leading either to the formation of mineral deposits or to their dissolution into the surrounding environments. Improving the understanding of biochemical processes would refine consolidated geochemical principles, based only on inorganic reactions, and create new, reliable geo(bio)tracers for natural resource exploration and management.

We invite interdisciplinary studies that bridge geochemistry, biochemistry, biology, hydrology, geology, and geophysics with modelling, fieldwork, or applied resource management aimed at exploring, monitoring, and sustainably managing natural resources. This session particularly encourages innovative approaches, including: (i) advanced analytical techniques, such as non-conventional stable and radiogenic isotopes, chemical and biological tracers, and geo(bio)indicators; (ii) novel sampling protocols; (iii) statistical tools and thermodynamic models for data interpretation; (iv) machine learning techniques for complex datasets. This session aims to advance both the fundamental understanding of fluid–rock systems and the sustainable use of natural resources and, on the other hand, open new frontiers into the development of biomarkers to better understand the fate of elements in the subsoil and unravel the dark secrets of the Earth’s hidden subsurface.

Numerous cases of induced/triggered seismicity have been reported in the last decades, resulting either directly or indirectly from injection/extraction activity related to geo-resources exploration and exploitation. Induced earthquakes felt by populations often negatively affect public perception of geo-energies, and may lead to the cancellation of important projects. Furthermore, large earthquakes can jeopardize wellbore stability and damage (surface) infrastructure. Thus, monitoring and modelling processes leading to fault slip, either seismic or aseismic, are critical to developing effective and reliable forecasting methodologies during deep underground exploitation. The complex interaction between injected/withdrawn fluids, subsurface geology, stress interactions, and resulting fault slip requires an interdisciplinary approach to understand the triggering mechanisms, and may require taking coupled thermo-hydro-mechanical-chemical processes into account.

In this session, we invite contributions from research aimed at investigating the interaction of the above processes during exploitation of underground resources, including hydrocarbon extraction, wastewater disposal, geothermal energy exploitation, hydraulic fracturing, gas storage and production, mining, and reservoir impoundment for hydro-energy. We particularly encourage novel contributions based on laboratory and underground near-fault experiments, numerical modelling, the spatiotemporal relationship between seismic properties, injection/ withdrawal parameters, and/or geology, and fieldwork. Contributions covering both theoretical and experimental aspects of induced and triggered seismicity at multiple spatial and temporal scales are welcome.

Faults and fracture zones are fundamental features of geological reservoirs that control the physical properties of the rock. As such, understanding their role in in-situ fluid behaviour and fluid-rock interactions can generate considerable advantages during exploration and management of reservoirs and repositories.

Physical properties such as frictional strength, cohesion and permeability of the rock impact deformation processes, rock failure and fault/fracture (re-)activation. Faults and fractures create fluid pathways for fluid flow and allow for increased fluid-rock interaction.

The presence of fluids circulating within a fault or fracture network can expose the host rocks to significant alterations of the mechanical and transport properties. This in turn can either increase or decrease the transmissibility of a fracture network, which has implications on the viability and suitability of subsurface energy and storage projects. Thus, it is important to understand how fluid-rock interactions within faults and fractures may alter the physical properties of the system during the operation of such projects. This is of particular interest in the case of faults as the injection/ remobilisation of fluids may affect fault/fracture stability, and therefore increase the risk of induced seismicity and leakage.

Fieldwork observations, monitoring and laboratory measurements foster fundamental understanding of relevant properties, parameters and processes, which provide important inputs to numerical models (see session “Faults and fractures in geoenergy applications 1: Numerical modelling and simulation”) in order to simulate processes or upscale to the reservoir scale. A predictive knowledge of fault zone structures and transmissibility can have an enormous impact on the viability of geothermal, carbon capture, energy and waste storage projects.

We encourage researchers on applied or interdisciplinary energy studies associated with low carbon technologies to come forward for this session. We look forward to interdisciplinary studies which use a combination of methods to analyse rock deformation processes and the role of faults and fractures in subsurface energy systems, including but not restricted to outcrop studies, monitoring studies, subsurface data analysis and laboratory measurements. We are also interested in research across several different scales and addressing the knowledge gap between laboratory scale measurements and reservoir scale processes.

Naturally fractured reservoirs are of great importance in various disciplines such as hydrogeology, hydrocarbon reservoir management, nuclear waste repositories, CO2 storage and geothermal reservoir engineering. This session addresses novel ideas as well as established concepts for the representation and numerical simulation of discontinuities and processes in fractured media.
The presence of fractures modifies the bulk physical properties of the original media by many orders of magnitudes and often introduces strongly nonlinear behaviour. Fractures also provide the main flow and transport pathways in the rock mass, dominating over the permeability of the rock matrix and creating anisotropic flow fields and transport.
Numerical modelling of such systems is especially challenging and often requires creative new ideas and solutions, for example the use of stochastic models. Understanding the hydraulic and mechanical properties of fractures and fracture networks thus is crucial for predicting the movement of any fluid such as water, air, hydrocarbons, or CO2.
The geologist toolboxes for modelling fractured rocks and simulating processes in fractured media experiences constant extension and improvement. Contributions are especially welcome from the following topics:

• Deterministic or stochastic approaches for structural construction of fractured media
• Continuous or discontinuous (DFN) modelling methods representing static hydraulic and/or mechanical characteristics of fractured media
• Simulation of dynamic processes, hydraulic and/or mechanical behaviour and THMC coupling in fractured media
• Deterministic and stochastic inversion methods for calibrating numerical models of fractured media
• Numerical modelling concepts of accounting for fractured properties specifically in groundwater, petroleum or geothermal management applications

We encourage researchers to elaborate on applied projects on the role of faults and fractures in subsurface energy systems in our session. We are interested in research across different scales and disciplines and welcome ECS warmly.

Geological media are a strategic resource for the forthcoming energy transition and their use for geo-energy technologies is increasing to mitigate the adverse effects of climate change. Subsurface engineering applications such as deep geothermal resource exploitation, Carbon Capture and Sequestration (CCS), natural gas or hydrogen storage, involve multi-physical processes in the porous and fractured rock, including fluid flow, solute and heat transport, rock deformation and geochemical reactions, which occur simultaneously and impact each other. The safe and efficient deployment of such geo-energy technologies is bounded to the adequate understanding of these coupled thermo-hydro-mechanical-chemical (THMC) processes, and predictive capabilities heavily rely on the quality of the integration between the input data (laboratory and field evidence) and the mathematical models describing the evolution of the multi-physical systems.
This session is dedicated to studies investigating some of these THMC interactions by means of mathematical, experimental, numerical, data-driven and artificial intelligence methods, as well as studies focused on laboratory characterization and on gathering and interpreting in-situ geological and geophysical evidence of the multi-physical behavior of rocks. Welcomed contributions include approaches covering applications of carbon capture and storage (CCS), geothermal systems, gas storage, energy storage, mining, reservoir management, reservoir stimulation, fluid injection-induced seismicity and radioactive waste storage.

Understanding subsurface resources requires linking pore-scale properties to reservoir-scale behaviour. This session highlights how advanced multi-scale rock and porous media characterisation, including scattering methods, CT imaging, NMR, laboratory testing, and field monitoring, can be integrated into upscaled thermo-hydro-mechanical-chemical-biological (THMCB) modelling. We invite contributions that connect detailed characterisation to constitutive models, constrain coupled process interactions, and reduce uncertainties in predicting subsurface performance. Applications may include CO₂ and H₂ storage, geothermal energy, waste disposal, and groundwater systems. Case studies that combine experimental data with modelling, as well as hybrid physics–data approaches, are particularly welcome. The session aims to bring together experimentalists, modellers, and practitioners to advance predictive tools for the safe and sustainable utilisation of geological resources.

As climate change accelerates, the transition to renewable energy systems, such as geothermal energy, underground hydrogen storage, and carbon capture and storage (CCS), is essential. These technologies introduce new challenges in the subsurface, for example, limited data availability, highly heterogeneous reservoirs, and complex thermal and multiphase fluid flow behavior.

Geo-modelling is a powerful tool for addressing these challenges. It allows to combine geological, geophysical, and petrophysical data; supports the simulation of multiphase fluid flow and coupled geomechanical behavior; and underpins the design of safe, efficient, and scalable subsurface systems. Geo-models for the energy transition must function across diverse spatial and temporal scales, perform reliably in data-scarce environments, and remain transparent and interpretable to both experts and decision-makers. As such, geo-modelling plays a vital role in the energy transition by delivering accurate and data-driven representations of the subsurface.

This session will explore advances in geo-modelling techniques, their practical applications, and the key challenges they address in the context of the energy transition. We welcome abstracts focusing on:
• Representative Elementary Volumes (REVs): methods to define and characterize the representative scale at which heterogeneous subsurface properties can be accurately averaged.
• Fluid flow modelling: single-phase and multiphase fluid flow simulations and their challenges in heterogeneous energy systems.
• Multi-scale modelling: upscaling methods for transforming fine-scale data models into reservoir-scale models, but also methods to combine models with varying scales.
• Sketch-based reservoir modelling: intuitive and rapid design of geological scenarios to capture their uncertainty in models.
• 3D subsurface modelling: advances in both process-based and object-based modelling techniques.
• Reservoir modelling for the energy transition: modelling approaches applied to geothermal energy, CCS, and hydrogen storage.
• Energy/Storage Efficiency and Socio-Economics: modelling the impact of subsurface uncertainties on the economic aspect of geo-engineering applications. This includes lifetime (thermal breakthrough) analysis for geothermal wells and (pressure) communication between closely situated CCS fields impacting injection efficiency and reservoir integrity.

Machine learning (ML) is advancing the fields of geotechnics and geosciences by enabling data-driven subsurface characterization, predictive modeling, and real-time decision support.
This session invites contributions on ML applications in geotechnical and geoenvironmental engineering. Topics may include slope stability, tunneling, foundation design, subsurface flow and transport, seismicity, and coupled hydro-mechanical processes. Studies leveraging supervised, unsupervised, and deep learning methods; physics-informed neural networks; and hybrid ML–finite element method frameworks are encouraged.
We also welcome work that integrates ML with monitoring data (e.g., Internet of Things (IoT) sensors, remote sensing), inverse analysis, and the development of digital twins for predictive maintenance, structural health monitoring, and hazard mitigation.
Submissions that demonstrate model interpretability, uncertainty quantification, benchmark comparisons, or hybrid data–model approaches are especially encouraged.

Dissolution, precipitation and chemical reactions between infiltrating fluid and the rock matrix alter the composition and structure of the rock, either creating or destroying flow paths. Strong, nonlinear couplings between the chemical reactions at mineral surfaces and fluid motion in the pores often lead to the formation of large-scale patterns: networks of caves and sinkholes in karst areas, wormholes induced by the acidization of petroleum wells, porous channels created as magma rises through peridotite rocks. Dissolution and precipitation processes are also relevant in many industrial applications: carbon storage or mineralization, oil and gas recovery, sustaining fluid circulation in geothermal systems, the long-term geochemical evolution of host rock in nuclear waste repositories or mitigating the spread of contaminants in groundwater.

With the advent of modern experimental techniques, these processes can now be studied at the microscale, with a direct visualization of the evolving pore geometry, allowing exploration of the coupling between the pore-scale processes and macroscopic patterns. On the other hand, increased computational power and algorithmic improvements now make it possible to simulate laboratory-scale flows while still resolving the flow and transport processes at the pore scale.

We invite contributions that seek a deeper understanding of reactive flow processes through interdisciplinary work combining experiments or field observations with theoretical or computational modeling. We seek submissions covering a wide range of spatial and temporal scales: from table-top experiments and pore-scale numerical models to the hydrological and geomorphological modelling at the field scale.

Why this short course
Earth and environmental sciences thrive on data diversity: from ocean temperatures to biodiversity records, from climate indicators to geological observations. Yet, this very diversity can also be a barrier: different datasets are described with different standards, stored in different formats, and are difficult to connect across research infrastructures. The ENVRI-Hub provides a set of tools to overcome these challenges. It offers researchers a unified framework to discover, access, and reuse complex and multidisciplinary data.

This short course will give researchers a practical introduction to how ENVRI-Hub workflows can directly support their own projects, to build more reproducible and impactful science.

Humanity is facing profound transformation challenges, including anthropogenic climate change, exposure to diverse natural hazards, digitalization, an increasing need for climate-neutral energy, growing exposure to air and water pollution affecting human and ecosystem health, and rising societal polarization. Densely populated urban areas and their surrounding regions are hubs of resource consumption as well as hotspots of vulnerability where natural and human-induced risks accumulate and resilience must be actively cultivated. Yet, urban areas are also places of innovation where new solutions can be co-designed, tested and amplified. Thus, urban resilience is influenced by socio-ecological and socio-technical dynamics. Up to now the role of surface and sub-surface geo-processes in the context of these dynamics is still underexplored. Therefore we invite contributions addressing how urban areas and their surroundings can adapt to, and shape ongoing societal and environmental transformations, particularly from this perspective. This includes but is not limited to tackling environmental stressors in cities, advancing monitoring, modeling as well as adaptation and mitigation strategies; research on water and geoenergy for integrated city development and co-designing just urban futures, embedding transformation processes in social practices and governance structures.

Clean-energy transitions and net-zero goals depend on materials and technologies that comprise complex and often fragile chains that stretch from mines and refineries to ports and project sites. The idealism of a rapid transition now collides with the realities of geopolitical tensions; disruptions cascading across chokepoints, with uneven social and environmental burdens along the way. On the one hand, in a fragmented world of tariffs, export controls, buyer clubs, and subsidy races, shocks at a few nodes can delay projects and shift costs and harm particular regions, workers, and communities, as well as the environment and ecosystem services. On the other hand, the rise of green industrial policies that aim to onshore or reshore value chains for clean energy transitions could create new opportunities if carefully designed and implemented. We invite interdisciplinary submissions across a range of these interconnected fields to confront the questions:
how resilient are these value chains,
who bears the risks and benefits, which risks in the value chains pose challenges to an equitable and nature-positive transition, and
what kind of opportunities exist that can help climate & sustainability goals while strengthening these value chains?

We welcome studies on just transitions and equity analyses linked to clean energy value-chain data, practical approaches across extraction and processing, recycling and circular design, or the design and implementation of green industrial policy. Contributions may examine who carries risks and who captures value; how technology and policy choices affect suppliers and communities; how governance and finance shape outcomes; and how impacts travel across scales. Adaptation insights are welcome when they clarify disruption risks or recovery times relevant to energy transitions.

We aim to surface where evidence is strong, where methods are missing, and what to measure next to make resilience and justice actionable.

The session will focus on blue-green infrastructure and other nature-based solutions that can contribute to sustainable water management in urban areas. Modern cities are facing rapid expansion, and water systems are becoming increasingly important from an environmental perspective, also from the environmental engineering point of view. An interdisciplinary debate would help raise awareness of urban planning and the design of public spaces for a better future development.

Social-science and humanities (SSH) research is crucial for informing ambitious, effective, just or societally acceptable climate action. This session highlights how SSH insights on social metabolism, labor transitions, perceptions and societal readiness, institutional dynamics, justice, needs/capabilities, and power relations can enrich and reshape diverse modeling approaches. We aim to provide a platform for interdisciplinary work that broadens the scope of what models and scenarios can represent, clarifies their limits, and fosters connections across methods.

We welcome contributions that:

Integrate SSH concepts and methods into integrated assessment models (IAMs), energy–economy–environment models, or other analytical frameworks

Use empirical and participatory approaches to inform model assumptions, structures, and constraints

Engage with normative dimensions such as fairness, feasibility, and societal acceptance

Connect justice issues to marginalized or disadvantaged communities, especially in the Global South

Address the role of governance, institutions, finance, and critically evaluate material and human needs in shaping transition pathways

Investigate social impacts of modeled scenarios (e.g., income, labor, or demand modeling)

We particularly encourage work that incorporates procedural, recognitional, transitional and other forms of justice, identifies how data gaps map onto justice gaps, and provides bi-directional feedback between social science and modeling communities. By convening these perspectives, the session seeks to advance interdisciplinary approaches that make climate and energy scenarios more relevant, inclusive, and impactful.

Forests and surrounding landscapes are interconnected, and any human activities are integral elements of the socio-ecological system. Forest landscape management usually involves multi-stakeholder interventions to negotiate and implement management actions for local livelihoods, health and well-being. In this context integrated Decision Support Systems (DSS) are needed that help to address ecosystem services at the landscape scale by linking forest, agricultural and landscape interactions. The main aim of this inter- and transdisciplinary session is to identify solutions that use new and innovative methodological approaches in decision support, focusing on holistic planning to enhance sustainable ecosystem management and address ecosystem services, risks, and uncertainties. Computerized decision support systems (DSS) are know to support planning and decision making in semi- and unstructured decision problems. In that context database systems are often linked with analytical models and expert knowledge to take informed and data-driven decisions and allow managers visualizations by various graphical and tabular means. The first generation of DSSs was typically designed to address relatively narrow, well-defined problems for only one ecosystem service (e.g. timber production or increasing the resistance against storms). There has been a trend towards the development of more integrated DSS that simultaneously cover a broader range of ES such as habitat for biodiversity conservation and water provision, but there are still few examples for landscape management. This session invites contributions that bring together the scientific advances in this direction by presenting frameworks off integrated DSS and advandced combinations of methods, models and data to support decison making.

As cities face mounting pressures from climate change, pollution, biodiversity loss, environmental degradation, and increasing social inequality, the need for inclusive, data-informed strategies and solutions has never been greater. This session explores how citizen science can support urban climate adaptation, environmental monitoring, and hazard management. We invite contributions that showcase practices in engaging with the public and in the use of citizen science data, whether through technological innovation or methods to strengthen social inclusion in participatory science. This session aims to highlight current integration of citizen science into environmental research and share approaches that expand the scale, scope, and impact of citizen science in urban contexts.

We are particularly interested in work that explores:
• High-spatial density, high-frequency, or high-volume citizen science datasets for environmental monitoring or hazard detection.
• New engagement models involving underrepresented or vulnerable groups in data collection, co-creation, and action.
• Pioneering or mainstreaming the use of sensing technologies for participatory data generation.
• Integration of citizen science with AI for real-time decision-making and scenario modeling.
• Case studies, demonstrating how citizen science can address data gaps, support community-led adaptation and policymaking in resource-constrained settings, especially in low- and middle-income countries.

This session seeks to foster dialogue across disciplines and geographies to better understand both the opportunities and challenges of integrating citizen science data and insights into research and evidence-based governance and planning systems of climate-resilient and inclusive cities. We invite researchers, practitioners, data scientists, technologists and others working at the intersection of citizen science, urban systems, and climate adaptation to contribute oral presentations promoting cross-sector exchange.

As climate change impacts are intensifying, the need for comprehensive adaptation is strongly increasing to withstand current climate hazard intensities, while it is becoming more evident that mitigation is key to ensure a sustainable future. Therefore, measures for climate adaptation and mitigation have to be tackled by cities, regions and countries in parallel. However, measures are often set-up, planned and implemented within one specific sector without regarding potential interdependencies with other sectors, or other areas. For instance, measures for decreased individual traffic reduce CO2 emissions while giving space for increased greening, therefore positively impacting both mitigation and adaptation.
Within this session we are looking forward to receiving contributions displaying possible processes, methods and tools to increase the awareness, considerations and assessment of interdependencies between mitigation and adaptation. These can be qualitatively and span from linking specific models to complex system dynamics approaches. Further, we encourage applications that describe potential formats to engage with stakeholders for an increased consideration of these interdependencies in local policies and regulations.

Urban areas are increasingly facing dual challenges of thermal discomfort and flooding, both aggravated by anthropogenic climate change. Addressing these hazards requires integrative computational modelling and machine learning frameworks that can assess, predict, and optimize the role of green adaptation strategies.
This session invites contributions that investigate how urban greening, from large-scale green infrastructure to fine-scale vegetation attributes such as species density and leaf morphology, can mitigate urban heat island intensity and thermal stress. We also welcome studies demonstrating how green infrastructure reduces flood impacts by attenuating flood peaks, enhancing infiltration, and protecting built environments.
We particularly encourage approaches that integrate urban climatology, hydrology, ecology, and data science, including:
Modelling of heat-flood interactions under varying green adaptation scenarios.
Machine learning and computational methods for hazard prediction and resilience assessment.
Modelling urban vegetation impacts on microclimate, runoff reduction, and biodiversity.
Urban heat island analyses and strategies for mitigation through green design.
Comparative studies across climate zones, cities, or adaptation typologies.
By bridging climate adaptation science with computational innovation, this session will highlight how nature-based solutions can build climate-resilient cities under global change.

Sitting under a tree, you feel the spark of an idea, and suddenly everything falls into place. The following days and tests confirm: you have made a magnificent discovery — so the classical story of scientific genius goes…

But science as a human activity is error-prone, and might be more adequately described as "trial and error". Handling mistakes and setbacks is therefore a key skill of scientists. Yet, we publish only those parts of our research that did work. That is also because a study may have better chances to be accepted for scientific publication if it confirms an accepted theory or reaches a positive result (publication bias). Conversely, the cases that fail in their test of a new method or idea often end up in a drawer (which is why publication bias is also sometimes called the "file drawer effect"). This is potentially a waste of time and resources within our community, as other scientists may set about testing the same idea or model setup without being aware of previous failed attempts.

Thus, we want to turn the story around, and ask you to share 1) those ideas that seemed magnificent but turned out not to be, and 2) the errors, bugs, and mistakes in your work that made the scientific road bumpy. In the spirit of open science and in an interdisciplinary setting, we want to bring the BUGS out of the drawers and into the spotlight. What ideas were torn down or did not work, and what concepts survived in the ashes or were robust despite errors?

We explicitly solicit Blunders, Unexpected Glitches, and Surprises (BUGS) from modeling and field or lab experiments and from all disciplines of the Geosciences.

In a friendly atmosphere, we will learn from each other’s mistakes, understand the impact of errors and abandoned paths on our work, give each other ideas for shared problems, and generate new insights for our science or scientific practice.

Here are some ideas for contributions that we would love to see:
- Ideas that sounded good at first, but turned out to not work.
- Results that presented themselves as great in the first place but turned out to be caused by a bug or measurement error.
- Errors and slip-ups that resulted in insights.
- Failed experiments and negative results.
- Obstacles and dead ends you found and would like to warn others about.
