ADELE – ADIABATIC COMPRESSED-AIR ENERGY

Compressed-air energy storage (CAES) is similar in its principle: during the phases of excess availability, electrically driven compressors compress air in a cavern to some 70 bar. For discharge of the stored energy, the air is conducted via an air turbine, which drives a generator. Just as in pumped storage, its power can be released very quickly.

Compressed air

Compressed air energy storage. Compressed air energy storage (CAES) is a method of compressing air when energy supply is plentiful and cheap (e.g. off-peak or high renewable) and storing it for later use. The main application for CAES is grid-scale energy storage, although storage at this scale can be less efficient compared to battery storage
