Mines can be given energy independence in that they can create their own renewable energy, create their own storage and provide energy as and when it is needed.
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.
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.
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.
Abandoned mine entrance in Oregon. (Reference image Thomas Shahan, Flickr.) An international team of researchers has developed a novel way to store energy by transporting sand into abandoned underground mines.
Energy storage systems are required to increase the share of renewable energy. Closed mines can be used for underground energy storage and geothermal generation. Underground closed mines can be used as lower water reservoir for UPHES. CAES systems store energy in the form of compressed air in an underground reservoir.
