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

A pneumatic air compressor is a machine that transforms a starting fuel — typically electricity, gasoline, or diesel — into potential energy in the form of pressurized air. Stored in an integrated tank, the air can be drawn upon to power tools — including wrenches, drills, paint sprayers, sanders, and riveters.

CAES, a long-duration energy storage technology, is a key technology that can eliminate the intermittence and fluctuation in renewable energy systems used for generating electric power, which is expected to accelerate renewable energy penetration [7], [11], [12], [13], [14].
Essentially, the term compressed air energy storage outlines the basic functioning of the technology.
