Abstract. Compressed air energy storage (CAES) is known to have strong potential to deliver high performance energy storage at large scales for relatively low costs compared with any other solution. Although only two large-scale CAES plant are presently operational, energy is stored in the form of compressed air in a vast number of

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
