About Compressed air energy storage ratio
In order to achieve a near- so that most of the energy is saved in the system and can be retrieved, and losses are kept negligible, a near-reversibleor an is desired.In ancompression process, the gas in the system is kept at a constant temperature throughout. This necessarily requires an exchange of heat with the gas; otherwise, the temperat. The compressed air energy storage (CAES) system generally adopts compressors and turbines to operate under a constant pressure ratio. The system working parameters cannot adapt to load change, which causes the system efficiency to be limited.
