This energy storage system functions by utilizing electricity to compress air during off-peak hours, which is then stored in underground caverns. When energy demand is elevated during the peak hours, the stored compressed air is released, expanding and passing through a turbine to generate electricity.
Compressed air energy storage may be stored in undersea caves in Northern Ireland. In order to achieve a near- thermodynamically-reversible process so that most of the energy is saved in the system and can be retrieved, and losses are kept negligible, a near-reversible isothermal process or an isentropic process is desired.
The compressed air is then stored in a dedicated pressurized reservoir, which can be either an underground cavern or an aboveground tank, typically maintained at a pressure of 40-80 bar. During the discharge phase, the elastic potential energy stored in the compressed air is harnessed.
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
Enter liquid air energy storage, which has no such geographic restrictions. This works by using electricity during periods of abundant wind and solar generation to clean, dry and refrigerate air until it liquefies. The liquid air is then stored in insulated tanks.
