What is compressed air energy storage?
Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.
What is the theoretical background of compressed air energy storage?
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.
What are the different types of compressed air energy storage systems?

How is compressed air used to store and generate energy?
Using this technology, compressed air is used to store and generate energy when needed . It is based on the principle of conventional gas turbine generation. As shown in Figure 2, CAES decouples the compression and expansion cycles of traditional gas turbines and stores energy as elastic potential energy in compressed air . Figure 2.
What is a compressed air energy storage expansion machine?
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.
