Compressed air energy storage (CAES) offers a method for storing compressed air within a sealed enclosure. Storage in a compressed air system allows users to supplement energy usage during high-demand periods, enhances air quality, and maintains system stability. The energy is recovered by allowing the air to decompress through a turbine.
The maximum capacity of the compressed air energy storage system can reach 100 MW. Its operation time lasts from hours to several days. In addition, the compressed air energy storage can be used to store and release for more than ten thousands of times. Its lifetime lasts for 40–50 years, which is close to the pumped storage power station [7–9].
In a diabatic compressed air energy storage (CAES) system, during the charging process, air is compressed by a compressor that is driven by a motor. During the compression process the air heats up and the heat is removed by a radiator. The energy is stored as compressed air in a cavern.
Energy storage systems are one solution to this problem and can easily increase a power plant’s output and efficiency. One such storage system uses compressed air to save electricity for when it is needed.
Fig. 11. High temperature advanced CAES operated adiabatically . 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 capital cost of using compressed air energy storage is around $1,500 per kilowatt and is considered relatively affordable when compared to other energy storage systems.
