Inside Clean Energy: Here''s How Compressed Air Can Provide
Compressed air energy storage is not a new concept. A 290-megawatt compressed air storage plant went online in 1978 in Huntorf, Germany, and remains in operation today.
Compressed Air Energy Storage (CAES)
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
