Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational as of.
Compression of air creates heat; the air is warmer after compression. Expansion removes heat. If no extra heat is added, the air will be much colder after expansion. If the heat generated during compression can be stored and used.
Compression can be done with electrically-poweredand expansion with ordriving to produce electricity.

Compressed air storage Compressed air can be stored either at constant volume (isochoric) or at constant pressure (isobaric). In case of constant volume storage, the pressure varies and thus indicates the state of charge. The most common example of isochoric storage is a steel pressure vessel or, at large scale, a salt cavern.
