Large geological storage of energy (e.g., hydrogen, heat), carbon dioxide, and wastes in porous media and engineered caverns is crucial for enabling the shift toward a sustainable, resilient, and low-carbon future. Achieving safe, efficient, and cost-effective operations at scale depends on the storage capacity and injectivity of the reservoir and the sealing performance and integrity of the confining units, faults, and wells, which are governed by a range of thermal, hydraulic, mechanical, chemical, and microbial processes. Thus, secure subsurface storage, together with public acceptance in essential technologies, demands geological expertise, continuous and effective monitoring, and careful assessment of potential risks.
This session offers a platform for interdisciplinary scientific exchange between different branches of storage expertise and aims to address challenges concerning the storage of fluids in geological reservoirs from core- to field-scale. We welcome analytical studies, computational simulations, laboratory experiments, data-driven analyses, developing monitoring techniques, and field-scale investigations to advance fundamental understanding and assessments of coupled physical and chemical processes involved in subsurface storage. We also encourage contributions that investigate specific challenges associated with the scaleup of geological storage technologies.
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. By comparing results across storage applications, geological settings, scales, and deployment levels, the session aims to identify transferable methodologies, common performance drivers, and scalable solutions for the safe and effective use of the subsurface as a multifunctional storage resource.
