Compressed air energy storage offers advantages such as large storage capacity, high safety, long lifespan, economic and environmental friendliness, and short construction periods. It is a long-duration energy storage technology comparable to pumped-storage hydroelectricity and is becoming a key focus for future energy storage development. Building on its foundation in heat exchange equipment, turbine equipment, and pressure vessel manufacturing, Harbin Electric Corporation keeps researching and developing CAES technology and key equipment. We supply equipment and perform system integration for CAES power plants, including heat exchange systems, storage systems, expansion systems, and power generation systems.
