Abandoned mine air energy storage technology

Can abandoned mines be used as compressed air storage systems?

Underground space in abandoned mines may be used as compressed air storage systems for CAES plants. The simplified schematic diagram of the CAES system is shown in Figure 1. The compressor and turbine facilities are installed above the ground, while the compressed air reservoir is underground.

Can abandoned coal mines be used as compressed air reservoirs?

In this paper, abandoned mines are proposed as underground reservoirs for large scale energy storage systems. A 200 m 3 tunnel in an abandoned coal mine was investigated as compressed air reservoir for A-CAES plants, where the ambient air is stored at high pressure.

Can abandoned mines be used as underground reservoirs?

Underground space from abandoned mines can be used as underground reservoirs for underground pumped storage hydropower (UPSH) and compressed air energy storage (CAES) systems [ 5, 6, 7, 8, 9, 10, 11 ].

How can abandoned mine facilities be used to generate energy?

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.

Can abandoned mines be used for energy storage?

For more information on the journal statistics, click here . Multiple requests from the same IP address are counted as one view. Million cubic meters from abandoned mines worldwide could be used as subsurface reservoirs for large scale energy storage systems, such as adiabatic compressed air energy storage (A-CAES).

Can underground space energy storage technology be used in abandoned coal mines?

The underground space resources of abandoned coal mines in China are quite abundant, and the research and development of underground space energy storage technology in coal mines have many benefits.
