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.
