Free QuoteIn low demand period, energy is stored by compressing air in an air tight space (typically 4.0~8.0 MPa) such as underground storage cavern. To extract the stored energy, compressed air is drawn from the storage vessel, mixed with fuel and combusted, and then expanded through a turbine.
For IA-CAES, the constant pressure in the air storage device is maintained during the charging and discharging process, as shown in Fig. 7 (c). A constant storage pressure is often achieved by applying a certain depth of water pressure and the air storage device is often constructed underwater.
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.

After heated and expanded, CO 2 at the turbine outlet absorbs the cold energy stored in the charging process and is condensed into a liquid state. The condensed liquid CO 2 is then stored in the low-pressure liquid CO 2 storage tank. Furthermore, the heat storage subsystem is basically the same as that of CAES.
