During times of low demand, energy is commonly captured by compressing and storing air in an airtight location (typically between 4.0 and 8.2 MPa, such as in an underground cavern), and then using the gas to generate energy at times of higher demand [16].
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.
Using this technology, compressed air is used to store and generate energy when needed . It is based on the principle of conventional gas turbine generation. As shown in Figure 2, CAES decouples the compression and expansion cycles of traditional gas turbines and stores energy as elastic potential energy in compressed air . Figure 2.

The adiabatic compressed air energy storage (A-CAES) system has been proposed to improve the efficiency of the CAES plants and has attracted considerable attention in recent years due to its advantages including no fossil fuel consumption, low cost, fast start-up, and a significant partial load capacity .
TES can also store thermal energy from other sources, such as solar energy and waste heat, to improve system efficiency. Thus, the temperature of the TES is related to the stages of the CMP; the lower the stages of the CMP, the higher the temperature of the TES.
