In adiabatic CAES systems (Fig. 6.2) the heat of compression is stored in one or more separate storage facilities so that it can be reused to heat up the air when it is withdrawn from the storage.Since this dispenses with the addition of combustion gas, this can be considered a pure power-to-power storage system.

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).
