Compressed air energy storage has a significant impact on the energy sector by providing large-scale, long-duration energy storage solutions. CAES systems can store excess energy during periods of low demand and release it during peak demand, helping to balance supply and demand on the grid.
Illustration of a compressed air energy storage process. CAES technology is based on the principle of traditional gas t urbine plants. As shown in Figu re gas turbine, compressor and combustor. Gas with high temperature and high pressure, which is turn drives a generator to generate electricity [20,21]. For a CAES plant, as shown in Figure 5, there
Appendix B presents an overview of the theoretical background on compressed air energy storage. Most compressed air energy storage systems addressed in literature are large-scale systems of above 100 MW which most of the time use depleted mines as the cavity to store the high pressure fluid.
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.
Air is compressed using compressors and is stored in the storage tanks. Over the surface storage tanks are used for lower rating and underground storage tanks are preferred in case of very high capacity plants. The compressor is run by the motor generator to which the excess available energy is fed.
In thermo-mechanical energy storage systems like compressed air energy storage (CAES), energy is stored as compressed air in a reservoir during off-peak periods, while it is used on demand during peak periods to generate power with a turbo-generator system.
