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 2024 . The Huntorf plant was initially developed as a load balancer for fossil-fuel-generated electricity

Adiabatic compressed air energy storage technology

Any CAES system is charged by using electricity to drive air compressors, resulting in compressed air and heat. In DCAES, the heat is extracted by using heat exchangers (HEX) and dissipated (being of low grade and therefore of low value), whereas the pressurized air is stored in a dedicated pressure vessel, herein referred to as the high-pressure (HP) store.
