Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.
Specifically, at the thermal storage temperature of 140 ℃, round-trip efficiencies of compressed air energy storage and compressed carbon dioxide energy storage are 59.48 % and 65.16 % respectively, with costs of $11.54 × 10 7 and $13.45 × 10 7, and payback periods of 11.86 years and 12.57 years respectively.
The “Energy Storage Grand Challenge” prepared by the United States Department of Energy (DOE) reports that among all energy storage technologies, compressed air energy storage (CAES) offers the lowest total installed cost for large-scale application (over 100 MW and 4 h).

The 290 MW×2h Huntorf power station in 1978 and the 110 MW×26 h McIntosh power station in 1991 are examples of traditional compressed air energy storage plants. Their efficiencies are 42 % and 53 % respectively. The sliding-pressure range of the gas storage facility from approximately 4.6 to 7.5 MPa .
The total installed energy storage reached 209.4 GW worldwide in 2022, an increase of 9.0% over the previous year . CAES, another large-scale energy storage technology with pumped-hydro storage, demonstrates promise for research, development, and application. However, there are concerns about technical maturity, economy, policy, and so forth.
