In the storage phase, air from the atmosphere is compressed using a device powered by “green electricity” generated by solar panels or wind turbines during off-peak hours. The compressed air is then stored in an underground cavern.
CAES stores potential energy in the form of pressurized air. When the air is released, it expands and passes through a turbine, which generates electricity. The amount of electricity generated depends on the pressure and the volume of the compressed air. What is the problem with compressed air energy storage?
For IA-CAES, the constant pressure in the air storage device is maintained during the charging and discharging process, as shown in Fig. 7 (c). A constant storage pressure is often achieved by applying a certain depth of water pressure and the air storage device is often constructed underwater.
Besides the system structure, the air storage device is also a key component of CAES system. It has an important impact on the safe, efficient and stable operation of the system. With the rapid growth of CAES, the research on air storage device has received much attention.
The first adiabatic CAES project; the heat that appears during compression is also stored, and then returned to the air when the air is expanded.

Compressed air energy storage technology is a promising solution to the energy storage problem. It offers a high storage capacity, is a clean technology, and has a long life cycle.
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
