Compressed Air Energy Storage (CAES) offers many benefits to the grid and the environment. It has a long lifespan and low maintenance costs, compared to other energy storage systems such as batteries.
The special thing about compressed air storage is that the air heats up strongly when being compressed from atmospheric pressure to a storage pressure of approx. 1,015 psia (70 bar). Standard multistage air compressors use inter- and after-coolers to reduce discharge temperatures to 300/350°F (149/177°C) and cavern injection air temperature
