Compressed air energy storage – schematics

Heat recovery is the central problem in compressed air energy storage.

During compression a large amount of electric energy is converted into heat.

In the APT-process heat of compression is stored separately from compressed air.

During expansion compressed air regains stored heat and drives turbines.

Good overall efficiency (closed cycle from electricity to electricity) results from heat recovery.
