The operation principle behind compressed air energy storage is simple. When there is excess electricity in a system, a fluid is compressed in a large impermeable cavity. The fluid remains in the cavity at high pressure until there is a need for power.
Schematic diagram of a compressed air energy storage (CAES) Plant. Air is compressed inside a cavern to store the energy, then expanded to release the energy at a convenient time. [...] Driven by global concerns about the climate and the environment, the world is opting for renewable energy sources (RESs), such as wind and solar.
Appendix B presents an overview of the theoretical background on compressed air energy storage. Most compressed air energy storage systems addressed in literature are large-scale systems of above 100 MW which most of the time use depleted mines as the cavity to store the high pressure fluid.
There are several compression and expansion stages: from the charging, to the discharging phases of the storage system. Research has shown that isentropic efficiency for compressors as well as expanders are key determinants of the overall characteristics and efficiency of compressed air energy storage systems .
S. Hari Charan Cherukuri, in Journal of Energy Storage, 2021 Compressed Air Energy Storage (CAES) is an option in which the pressure energy is stored by compressing a gas, generally air, into a high pressure reservoir. The compressed air is expanded into a turbine to derive mechanical energy and hence run an electrical generator.
In diabatic compressed air energy storage systems, off-peak electricity is transformed into energy potential for compressed air, and kept in a cavern, but given out when demand is high. Fig. 17 shows the schematic of a diabatic compressed air energy storage system. Fig. 17. Diagram of diabatic compressed air energy storage system .

The Compressed Air Energy Storage Principle. A CAES plant requires two principal components, a storage vessel in which compressed air can be stored without loss of pressure and a compressor/expander to charge the storage vessel and then extract the energy again.

In 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.
