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 intention of this paper is to give an overview of the current technology developments in compressed air energy storage (CAES) and the future direction of the technology development in this area.
OverviewTypesCompressors and expandersStorageEnvironmental ImpactHistoryProjectsStorage thermodynamics
Compression of air creates heat; the air is warmer after compression. Expansion removes heat. If no extra heat is added, the air will be much colder after expansion. If the heat generated during compression can be stored and used during expansion, then the efficiency of the storage improves considerably. There are several ways in which a CAES system can deal with heat. Air storage can be adiabatic, diabatic, isothermal, or near-isothermal.

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.
Compared with other energy storage technologies, CAES is proven to be a clean and sustainable type of energy storage with the unique features of high capacity and long-duration of the storage.
The concept of CAES is derived from the gas-turbine cycle, in which the compressor (CMP) and turbine operate separately. During charging, air is compressed and stored with additional electricity, and the compression heat is stored in a thermal energy storage (TES) unit for future use.
Unlike traditional battery systems that rely on electrochemical reactions, like lithium-ion batteries and superconducting magnetic energy storage systems, CAES presents a scalable solution capable of storing larger amounts of energy for extended periods. This makes it a compelling alternative in the renewable energy landscape.
Siemens Energy CAES improves utilization of renewable energy resources by absorbing GW-hours of energy that would otherwise be curtailed and provides grid balancing and reserve services with lower fuel usage and carbon footprint than other controllable resources.
