Compressed air energy storage (CAES) is a technology employed for decades to store electrical energy, mainly on large-scale systems, whose advances have been based on improvements in thermal mana.
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.
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.
To address the challenge, one of the options is to detach the power generation from consumption via energy storage. The intention of this paper is to give an overview of the current technology developments in compressed air energy storage (CAES) and the future direction of the technology development in this area.
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.
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. Three main concepts are researched; diabatic, adiabatic and isothermal.
There are several compression and expansion stages: from the charging, to the discharging phases of the storage system. Research has shown that isentropic efficiency for compressors as well as expanders are key determinants of the overall characteristics and efficiency of compressed air energy storage systems .
