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.
Among many energy storage technologies, currently mature energy storage technologies include pumped storage, electrochemical energy storage and compressed air energy storage (CAES) [7].

Compressed-air energy storage (CAES) is a technology in which energy is stored in the form of compressed air, with the amount stored being dependent on the volume of the pressure storage vessel, the pressure at which the air is stored, and the temperature at which it is stored.

The operation of a conventional compressed air energy storage system is described as follows: excess electricity during off-peak hours is used to drive a 2-stage compressor with intercooling. After the compression, the compressed air (40–70 bar) is led to an after-cooler before it gets stored in an underground storage reservoir.
2.1. How it all began The fundamental idea to store electrical energy by means of compressed air dates back to the early 1940s [2] then the patent application "Means for Storing Fluids for Power Generation" was submitted by F.W. Gay to the US Patent Office [3]..

Compressed air energy storage (CAES) is a method of compressing air when energy supply is plentiful and cheap (e.g. off-peak or high renewable) and storing it for later use. The main application for CAES is grid-scale energy storage, although storage at this scale can be less efficient compared to battery storage, due to heat losses.
Compressed air energy storage (CAES) is a mechanical-based energy storage technology, in which compressed air is utilized to produce power at a later time [19].
