The global compressed air energy storage (CAES) market size reached USD 6.6 Billion in 2024. Looking forward, IMARC Group expects the market to reach USD 35.1 Billion by 2033, exhibiting a growth rate (CAGR) of 19.49% during 2025-2033. The burgeoning energy sector, rising production of electricity, and the growing employment of CAES in offshore wind turbines represent some of the key factors driving the market.
Compressed air energy storage (CAES) is a method of storing energy by compressing air in an underground storage reservoir. It relies on the gas turbine cycle that is used to compress air using a rotary compressor. It helps retrieve stored energy by allowing the air to expand, which pushes high-pressure air through a turbine to create electricity. It is used to supplement energy usage during high-demand periods, enhance air quality, and maintain system stability. It allows energy companies to provide sufficient energy for the entire service area without the need for added energy production. It reduces dependency on the electrical grid and decreases energy charges and operational overhead. It enhances power grid stability by lowering the strain on the electrical infrastructure and improving energy reliability. It offers a long shelf-life as CAES allows the compressor to unload before starting again and reduces short cycling. As it requires little maintenance costs due to reduced compressor maintenance frequency, the demand for CAES is rising across the globe.
At present, there is a rise in the production of electricity from renewable sources, such as wind, solar, and water energy, to meet the supply and demand for electricity across the globe. This, along with the increasing utilization of CAES by electricity system operators and electricity generators to store electricity, represents one of the key factors supporting the growth of the market. In addition, the growing demand for CAES to ensure the provision of the electrical grid with energy during peak demand periods is positively influencing the market. Moreover, there is an increase in the demand for isothermal storage that relies on heat exchangers to always keep the internal and external temperatures same. This, coupled with the thriving energy sector around the world, is catalyzing the demand for CAES. Apart from this, the growing employment of CAES in offshore wind turbines due to its cost-effectiveness and environment-friendliness is offering a favorable market outlook. In line with this, the increasing demand for CAES to ensure the stability of the aging power grid and replace coal-based electricity generation with natural gas is providing lucrative growth opportunities to industry investors. Additionally, the rising awareness among the masses about the benefits of using CAES, such as increased energy reliability, is strengthening the growth of the market.
