As an efficient energy storage method, thermodynamic electricity storage includes compressed air energy storage (CAES), compressed CO 2 energy storage (CCES) and pumped thermal energy storage (PTES).
A compressed air energy storage power plant functions in a way similar to a hydropower plant, yet the storage medium is changed from water to compressed air. At utility scale, cheap electricity generated during off-peak periods is utilized to compress air into an underground cavern at a pressure 40–80 bar, which is then released next day to run gas …
4.3.1 Operating Principle. Compressed air energy storage is based on the compression of air and storage in geological underground voids (e.g., salt caverns) at pressures of around 100 bar. When discharging, the compressed air is released and expanded to drive a gas turbine to generate electricity. As air cools down during expansion, it has to be heated …
