Compressed-air energy storage (CAES) is a commercialized electrical energy storage system that can supply around 50 to 300 MW power output via a single unit (Chen et al., 2013, Pande et al., 2003). It is one of the major energy storage technologies with the maximum economic viability on a utility-scale, which makes it accessible and adaptable

The working pressure in the CAES system determines the required volume of the storage cavern depending on the amount of accumulated energy: for the air pressure in the cavern of about 8 MPa the density of stored energy is 7.5 kWh/m 3, while for the pressure of 2 MPa the density of energy stored decreases to only 2 kWh/m 3.
