This chapter focuses on compressed air energy storage technology, which means the utilization of renewable surplus electricity to drive some compressors and thereby produce high-pressure air which can later be used for power generation. The chapter goes through the definitions and various designs of this technology.
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.
Schematic diagram of a compressed air energy storage (CAES) Plant. Air is compressed inside a cavern to store the energy, then expanded to release the energy at a convenient time. [...] Driven by global concerns about the climate and the environment, the world is opting for renewable energy sources (RESs), such as wind and solar.
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 a Compressed Air Energy Storage system, the compressed air is stored in an underground aquifer. Wind energy is used to compress the air, along with available off-peak power. The plant configuration is for 200MW of CAES generating capacity, with 100MW of wind energy.
