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.
The use of closed mines for the implementation of underground energy storage plants and geothermal energy plants has important environment benefits, but usually higher operation and maintenance costs (O&M) compared to conventional systems.
Based on this strategy, thermal energy storage systems represent an important foundation for the increased use of renewable energies. The transition to a sustainable energy supply requires the provision of large electrical as well as thermal storage capacities.
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.
Closed mines can be used for the implementation of plants of energy generation with low environmental impact. This paper explores the use of abandoned mines for Underground Pumped Hydroelectric Energy Storage (UPHES), Compressed Air Energy Storage (CAES) plants and geothermal applications.
