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.
