The compressed air energy storage (CAES) system is a very complex system with multi-time-scale physical processes. Following the development of computational technologies, research on CAES system model simulation is becoming more and more important for resolving challenges in system pre-design, optimization, control and implementation.
This energy storage system functions by utilizing electricity to compress air during off-peak hours, which is then stored in underground caverns. When energy demand is elevated during the peak hours, the stored compressed air is released, expanding and passing through a turbine to generate electricity.
Appendix B presents an overview of the theoretical background on compressed air energy storage. Most compressed air energy storage systems addressed in literature are large-scale systems of above 100 MW which most of the time use depleted mines as the cavity to store the high pressure fluid.
The reverse operation of both components to each other determines their design when integrated on a compressed air energy storage system. The screw and scroll are two examples of expanders, classified under reciprocating and rotary types.

Compressed air energy storage has a significant impact on the energy sector by providing large-scale, long-duration energy storage solutions. CAES systems can store excess energy during periods of low demand and release it during peak demand, helping to balance supply and demand on the grid.
During the discharge, the heat-storage releases its energy into the compressed air so that no gas co-combustion to heat the compressed air is needed in order to prevent the turbines from freezing, making it a real energy storage with a theoretical efficiency of approximately 70% and vastly carbon dioxide (CO 2) neutral.
