What is the theoretical background of compressed air energy storage?

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.

What happens when compressed air is removed from storage?

Upon removal from storage, the temperature of this compressed air is the one indicator of the amount of stored energy that remains in this air. Consequently, if the air temperature is too low for the energy recovery process, then the air must be substantially re-heated prior to expansion in the turbine to power a generator.

How is air compressed?

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.

Why is adiabatic compressed air energy storage less efficient than thermal energy storage?

Adiabatic compressed air energy storage without thermal energy storage tends to have lower storage pressure, hence the reduced energy density compared to that of thermal energy storage . The input energy for adiabatic CAES systems is obtained from a renewable source.

Why do compressed air energy storage systems have greater heat losses?

Compressed air energy storage systems may be efficient in storing unused energy, but large-scale applications have greater heat losses because the compression of air creates heat, meaning expansion is used to ensure the heat is removed [, ]. Expansion entails a change in the shape of the material due to a change in temperature.
