The main exergy storage system is the high-grade thermal energy storage. The reset of the air is kept in the low-grade thermal energy storage, which is between points 8 and 9. This stage is carried out to produce pressurized air at ambient temperature captured at point 9. The air is then stored in high-pressure storage (HPS).

In the adiabatic storage method, the heat, which is produced by compression, is kept and returned into the air, as it is expanded to generate power.
The performance of compressed air energy storage systems is centred round the efficiency of the compressors and expanders.
