Market Definition
Compressed air energy storage (CAES) is a form of mechanical energy storage that converts electricity into compressed air and later back into electricity when needed. In the charging phase, an electric motor powers a compressor that compresses ambient air and stores it in a reservoir such as an underground cavern, above-ground tank, or underwater balloon. During the discharging phase, the stored air is released and expanded through a turbine, which drives a generator to produce electricity. Compressed air energy storage (CAES) is emerging as a critical long-duration energy storage technology for stabilizing modern power grids. With the rapid growth of renewable energy sources such as wind and solar, CAES provides a reliable solution to address intermittency by storing excess electricity and delivering it back when demand rises. Compared to conventional batteries, CAES offers advantages such as longer operational lifespans, grid-level scalability capacities, low maintenance requirements, and the potential for zero-emission operation when deployed in adiabatic configurations.
