Finally, a CAES plant could be established, using the upper mine galleries for underground air storage; the fact that Lieres is a “dry mine” is ideal for this type of system. Thus, the abandoned mine facilities are efficiently used to generate both electrical and thermal renewable energy. Fig. 5.
International scientists have invented a revolutionary energy storage method by transferring sand into abandoned subterranean mines. Underground Gravity Energy Storage (UGES) is a revolutionary approach that promises an efficient long-term energy storage method while maximizing the use of abandoned mining sites.
The 2020 Cost and Performance Assessment analyzed energy storage systems from 2 to 10 hours. The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations.
Therefore, by 2050, if the energy storage proportion for solar and wind energy reaches 10%, and 50% of Class A salt caverns and 20% of Class B salt caverns are reconstructed for CAES, the total energy storage investment cost will be $3526.2 million.
Underground energy storage and geothermal applications are applicable to closed underground mines. Usually, UPHES and geothermal applications are proposed at closed coal mines, and CAES plants also are analyzed in abandoned salt mines. Geothermal power plants require flooded mines, which generally have closed more than 5 years ago.
