The maximum capacity of the compressed air energy storage system can reach 100 MW. Its operation time lasts from hours to several days. In addition, the compressed air energy storage can be used to store and release for more than ten thousands of times. Its lifetime lasts for 40–50 years, which is close to the pumped storage power station [7–9].
Compressed air energy storage system is mainly implemented in the large scale power plants, owing to its advantages of large capacity, long working hours, great number of charge–discharge cycles. The maximum capacity of the compressed air energy storage system can reach 100 MW. Its operation time lasts from hours to several days.
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.
Compressed air energy storage systems may be efficient in storing unused energy, but large-scale applications have greater heat losses because the compression of air creates heat, meaning expansion is used to ensure the heat is removed [, ]. Expansion entails a change in the shape of the material due to a change in temperature.
Compressed air energy storage may be stored in undersea caves in Northern Ireland. In order to achieve a near- thermodynamically-reversible process so that most of the energy is saved in the system and can be retrieved, and losses are kept negligible, a near-reversible isothermal process or an isentropic process is desired.
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.

3.1 Simplified Energy Storage Equations. As useful background for understanding how CAES works, we start with the first law of thermodynamics for open systems (mass transfer non-zero), which says that the change in energy of a system is equal to the heat flow in/out, the work done on/by the system, and the change in energy due to changes in …
