Alongside with pumped hydroelectricity storage, compressed air energy storage (CAES) is among the few grid-scale energy storage technology with power rating of 100 s MW [6], [7]. CAES operates in such a way that electrical energy is stored in the form of compressed air confined in a natural or artificial reservoir.
The round tip efficiency of Isothermal compressed air energy storage system is high compared to that of other compressed air energy storage systems.

Compressed-air energy storage can also be employed on a smaller scale, such as exploited by air cars and air-driven locomotives, and can use high-strength (e.g., carbon-fiber) air-storage tanks. In order to retain the energy stored in compressed air, this tank should be thermally isolated from the environment; otherwise, the energy stored will …

Recently, CAESA (compressed air energy storage in aquifers) has been proposed and studied because aquifers are more widely available than salt domes. In addition, the cost of CAESA could be as low as 0.11 $/KW h which is more attractive than the cost of CAESC (compressed air energy in caverns) (2 $/KW h) [9]..

It is noted that there is no need to verify the irrelevance of the time step because an adaptive time step is used in COMSOL Multiphysics 6.0. Therefore, only the grid irrelevance is verified. By taking Case 1 (i.e., m in = 18 kg/s, T C, in = 600 K, PCM1:PCM2:PCM3 = 1:1:3, and d PCM1 = 20 mm, d PCM2 = 20 mm, d PCM3 = 30 mm) …
The typical large-scale physical energy storage systems are divided into both the pumped storage and the compressed air energy storage. Pumped storage power stations have many advantages [11], such as high efficiency and long service life, but their construction is greatly limited by geographical conditions.
The creep test results show that the accelerated creep stage does not occur in the creep process of salt rock. Therefore, the nonlinear viscoplastic body in the creep model does not work. In other words, parameters m, n, σ s and η B0 are not considered in the calculation. are not considered in the calculation.
