Compressed Air Energy Storage has been in use for more than 20 years in demonstration projects, and two facilities — one at 290 MW in Huntorf, Germany that began operations in 1978, and another in Alabama, that began operating in 1991. The Compressed Air Energy Storage facility in Alabama is rated at 100 MW.

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 …
