Compressed air energy storage is a promising technique due to its efficiency, cleanliness, long life, and low cost. This paper reviews CAES technologies and seeks to demonstrate CAES''s models, fundamentals, operating modes, and classifications.
2.2. CAES operational parameters. CAES devices store electrical energy by using an electric motor to compress air, which is then stored in a reservoir (typically an underground formation). Compressed air is then used at a later time to generate electricity by expanding the compressed air through a series of turbines.
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.

2 Storage area conditions. You should only store gas cylinders in areas that are well-ventilated and properly illuminated. Compressed gas storage areas should be identified using proper signage and located away from sources of excess heat, open flame or ignition, and electrical circuits. They should not be located in enclosed or subsurface areas.
