The CHEST (Compressed Heat Energy STorage) concept for
An alternative concept for thermo-mechanical energy storage is based on heat transformation. According to Fig. 1 (left), electricity W mech is used to increase the enthalpy of Q low taken from a low temperature reservoir during the charging cycle. After transformation, the heat Q high is transferred to a reservoir/thermal storage. During
Compressed Air Energy Storage
The technological concept of compressed air energy storage (CAES) is more than 40 years old. Compressed Air Energy Storage (CAES) was seriously investigated in the 1970s as a means to provide load following and to meet peak demand while maintaining constant capacity factor in the nuclear power industry.

A review on compressed air energy storage: Basic principles, past
General concept of compressed air energy storage. The basic concept of CAES is rather simple. The storage is charged by the use of electrically driven compressors, which convert the electric energy into potential energy, or more precisely exergy, of pressurized air. The pressurized air is stored in CAS volumes of any kind (see

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
