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.

Compressed air energy storage may be stored in undersea caves in Northern Ireland. In order to achieve a near- thermodynamically-reversible process so that most of the energy is saved in the system and can be retrieved, and losses are kept negligible, a near-reversible isothermal process or an isentropic process is desired.
Calculate the storage volume of compressed air or other gases. The storage volume for a compressed gas can be calculated by using Boyle's Law pa Va = pc Vc = constant (1) where pa = atmospheric pressure (14.7 psia, 101.325 kPa) Va = volume of the gas at atmospheric pressure (cubic feet, m3)
Compressed-air energy storage can also be employed on a smaller scale, such as exploited by air cars and air-driven locomotives, and can use high-strength (e.g., carbon-fiber) air-storage tanks.
The high-pressure and high-temperature air is cooled before being stored in an air reservoir. The thermal energy can be dissipated into the atmosphere, stored in TES, or used for heating applications. In the discharging process, stored high-pressure air is released whenever the electricity is required.
The storage volume for a compressed gas can be calculated by using Boyle's Law pa Va = pc Vc = constant (1) where pa = atmospheric pressure (14.7 psia, 101.325 kPa) Va = volume of the gas at atmospheric pressure (cubic feet, m3) pc = pressure after compression (psi, kPa)
