The underground space for energy storage mainly includes porous or fractured porous media (e.g., depleted oil and gas reservoirs, aquifers) and caverns (e.g., salt caverns, rock caves, abandoned mines or pits) (Jannel and Torquet, 2021) (Fig. 3). The depth can range from several hundred meters to several kilometers (Kabuth et al., 2017).
Energy, gases, and solids in underground sites are stored in mining excavations, natural caverns, salt caverns, and in the pore spaces of rock formations. Aquifer formations are mainly isolated aquifers with significant spreading, permeability, and thickness, possessing highly mineralized non-potable waters. This study discusses the
Large-scale storage of natural gas,compressed air,petroleum and hydrogen by deep salt caverns is one of the key development directions of deep
Unlike battery energy storage, the energy storage medium of UGES is sand, which means the self-discharge rate of the system is zero, enabling ultra-long energy storage times. Furthermore, the use of sand as storage media alleviates any risk for contaminating underground water resources as opposed to an underground pumped
