An overview of underground energy-related product storage and sequestration

Storage of energy-related products in the geologic subsurface provides reserve capacity, resilience, and security to the energy supply chain. Sequestration of energy-related products ensures long-term isolation from the environment and, for CO2, a reduction in atmospheric emissions. Both porous-rock media and engineered caverns can provide the large storage volumes needed today and in the future. Methods for site characterization and modeling, monitoring, and inventory verification have been developed and deployed to identify and mitigate geologic threats and hazards such as induced seismicity and loss of containment. Broader considerations such as life-cycle analysis; environment, social and governance (ESG) impact; and effective engagement with stakeholders can reduce project uncertainty and cost while promoting sustainability during the ongoing energy transition toward net-zero or low-carbon economies
