As the global demand for carbon neutrality intensifies, CO2 geological sequestration has emerged as a key method for mitigating carbon emissions. This process involves the long-term storage of CO2 in deep geological formations such as depleted oil and gas reservoirs, saline aquifers, and unmineable coal seams. While the core of CO2 sequestration lies in the safe and permanent storage of carbon, recent advancements suggest that its potential extends far beyond carbon management alone. The coupling of CO2 geological sequestration with other subsurface technologies—such as energy storage, brine extraction, geothermal development, and underground waste disposal—offers a multidimensional approach to resource utilization and environmental sustainability. The session on CO2 Geological Sequestration and Beyond aims to delve into the synergies between CO2 sequestration and these emerging technologies. By exploring the possibilities and feasibility of coupling these technologies, the sub-forum seeks to foster discussions on how integrated subsurface solutions can contribute to achieving zero carbon goals while simultaneously addressing global energy and resource challenges.
