3.1.5 Compressed Air Storage. 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.
Moreover, technological efforts have led to the development of some derivative concepts based on CAES, such as Liquid Air Energy Storage (LAES) [44, 45], Underwater Compressed Air Energy Storage (UW-CAES) [46, 47], and Steam Injection Compressed Air].
The park-integrated energy system can achieve the optimal allocation, dispatch, and management of energy by integrating various energy resources and intelligent control and monitoring. Flexible load participation in scheduling can reduce peak and valley load, optimize load curves, further improve energy utilization efficiency, and

Among the large-scale energy storage solutions, pumped hydro power storage and compressed air energy storage both have a high efficiency of ~70 % but suffer from geographical constraints. In comparison, clean hydrogen storage belongs to the future, which is expensive, with currently low efficiency of ~20 % [ 3 ].
To address the challenge, one of the options is to detach the power generation from consumption via energy storage. The intention of this paper is to give an overview of the current technology developments in compressed air energy storage (CAES) and the future direction of the technology development in this area.
Shareable energy infrastructure is universally used in industrial parks and generally has a long service lifetime27 –29; thus, the GHG emissions from industrial parks are locked in.
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
