Abstract. A compressed air energy storage (CAES) system is an electricity storage technology under the category of mechanical energy storage (MES) systems, and is most appropriate for large-scale use and longer storage applications. In a CAES system, the surplus electricity to be stored is used to produce compressed air at high pressures.

As the isothermal compressor tanks fill with water, a pump pressurizes the water. As the air pressure rises, compressed air is pushed into one of the compressed air storage tanks. Using compressed air,

Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational . The Huntorf plant was initially developed as a load balancer for fossil-fuel-generated electricity

Among the available energy storage technologies, Compressed Air Energy Storage (CAES) has proved to be the most suitable technology for large-scale energy storage, in addition to PHES [10].
