Renewable and Sustainable Energy Reviews, 2011, 15 (1): 839-844. <p>Large-scale underground energy storage technology uses underground spaces for renewable energy storage, conversion and usage. It forms the technological basis of achieving carbon peaking and carbon neutrality goals.
For these different types of underground energy storage technologies there are several suitable geological reservoirs, namely: depleted hydrocarbon reservoirs, porous aquifers, salt formations, engineered rock caverns in host rocks and abandoned mines.
Underground Thermal Energy Storage (UTES) A thermal energy storage is a system that can store thermal energy by cooling, heating, melting, solidifying or vaporizing a material , such as hot-water, molten-salt or a phase-change material. Sensible heat storage (SHS) relies on the temperature variation of a solid or liquid (e.g. water).
The proposed technology, called Underground Gravity Energy Storage (UGES), can discharge electricity by lowering large volumes of sand into an underground mine through the mine shaft.
The site selection for underground energy storage is dependent upon several factors, mainly related to geological and engineering issues, such as: the type of candidate rocks, structural issues, tectonics and seismicity issues, hydrogeological and geothermal issues and also geotechnical criteria.
