  • Compressed Air Energy Storage - an overview ...

    Compressed air energy storage (CAES) is based around the gas turbine cycle. Surplus power is used to compress air using a rotary compressor and then store it, often in an underground chamber. When the power is required, it is released from the chamber and passed through an air turbine that generates electricity from the flow of high pressure air.
