Abstract. 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.
In low demand period, energy is stored by compressing air in an air tight space (typically 4.0~8.0 MPa) such as underground storage cavern. To extract the stored energy, compressed air is drawn from the storage vessel, mixed with fuel and combusted, and then expanded through a turbine.
A CAES with an isothermal design was proposed and developed to reduce energy loss. In this system, the air is compressed and stored using an isothermal air compression method. When electricity is required, isothermal air expansion releases air from the storage cavern to generate power [ 27 ]. 2.1.
This compressed air can be released on demand to produce electrical energy via a turbine and generator. This chapter describes various plant concepts for the large-scale storage of compressed air, and presents the options for underground storage, and their suitability in accordance with current engineering practice.

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 . The Huntorf plant was initially developed as a load balancer for fossil-fuel-generated electricity
