Compressed-air-energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational as of 2024.
The performance of compressed air energy storage systems is centred round the efficiency of the compressors and expanders. It is also important to determine the losses in the system as energy transfer occurs on these components. There are several compression and expansion stages: from the charging, to the discharging phases of the storage system.
For the advanced adiabatic compressed air energy storage system depicted in Fig. 11, compression of air is done at a pressure of 2.4 bars, followed by rapid cooling. There is considerable waste of heat caused by the exergy of the compressed air. This occurs due to two factors.
The main limitation for this technology has to do with the start up, which is currently between 10 and 15 min because of the thermal stress being high. The air is first compressed to 2.4 bars during the first stage of compression. Medium temperature adiabatic compressed air energy storage system depicted in Fig. 13. Fig. 13.
Expansion machines are designed for various compressed air energy storage systems and operations. An efficient compressed air storage system will only be materialised when the appropriate expanders and compressors are chosen. The performance of compressed air energy storage systems is centred round the efficiency of the compressors and expanders.
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.
Compressed Air Energy Storage: Types, systems and applications
Compressed air energy storage (CAES) uses excess electricity, particularly from wind farms, to compress air. Re-expansion of the air then drives machinery to recoup the electric power. Prototypes have capacities of several hundred MW. Challenges lie in conserving the thermal energy associated with compressing air and leakage of that heat, materials, power electronics, …
