2 Overview of compressed air energy storage. Compressed air energy storage (CAES) is the use of compressed air to store energy for use at a later time when required [41–45]. Excess energy generated from renewable energy sources when demand is low can be stored with the application of this technology.
READ MOREThe technology of storing energy by compressing air and keeping it in a suitable reservoir. Surplus electrical energy is used to compress the air, which is stored in an underground cavern or in a special container. Old mines are often used as suitable spaces. When needed, the air is released on an air turbine to produce electricity.

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 has been built in Huntorf, Germany, and is still operational. The Huntorf plant was initially developed as a load balancer for fossil fuel-generated electricity, the gl
