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.
Compressed air energy storage (CAES) systems usually operate under off-design conditions due to load fluctuations, environmental factors, and performance characteristics of the system. Thus, to improve design and operation characteristics, it is important to study off-design performance of CAES systems.
Energy storage by isothermal compression of air seems to be a promising solution. Compressions close to isothermal evolutions can be obtained by using liquid pistons.
