In particular focus has been on avoiding the loss of energy by cooling during compression. Instead the idea is to store the internal energy from the compression as well and use it regeneratively for heating air to the turbine. Grazzini [14] has studied such a configuration and finds an efficiency of 72%.
Compressed air | energy.gov
Compressed air energy storage (CAES) is a method of compressing air when energy supply is plentiful and cheap (e.g. off-peak or high renewable) and storing it for later use. The main application for CAES is grid-scale energy storage, although storage at this scale can be less efficient compared to battery storage, due to heat losses.
