The operation principle behind compressed air energy storage is simple. When there is excess electricity in a system, a fluid is compressed in a large impermeable cavity. The fluid remains in the cavity at high pressure until there is a need for power.
Using compressed air to store energy is one of the energy storage methods. In this study, a small scale compressed air energy storage (CAES) system is designed and modeled. The energy storage capacity of designed CAES system is about 2 kW.
S. Hari Charan Cherukuri, in Journal of Energy Storage, 2021 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.
By assuming a starting volume of 1 m 3 and a pressure of 2 × 10 5 Pa, if the gas is compressed to 0.4 m 3 at constant temperature, the amount of stored energy is 1.8 × 10 J. This is a much higher energy density than that of magnetic or electric fields.
Compressed air energy storage systems may be efficient in storing unused energy, but large-scale applications have greater heat losses because the compression of air creates heat, meaning expansion is used to ensure the heat is removed [, ]. Expansion entails a change in the shape of the material due to a change in temperature.
In a Compressed Air Energy Storage system, the compressed air is stored in an underground aquifer. Wind energy is used to compress the air, along with available off-peak power. The plant configuration is for 200MW of CAES generating capacity, with 100MW of wind energy.

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 as of 2024 . The Huntorf plant was initially developed as a load balancer for fossil-fuel-generated electricity
