Abstract:
A compressed air system energy storage and recovery system has a compressed air tank structured to store compressed air above 200 bars, a heat storage unit containing a heat transfer fluid and having a latent heat storage material, and a heat exchanger. The heat exchanger extracts heat from compressed ambient air above 200 bars for storage and to heat compressed air from the tank above 200 bars prior to expansion and use to recover energy in the air motor. Efficiency of energy storage and heat exchange is improved using pressures above 200 bars.

Claim (Index 19):
A method of compressed air energy storage and regeneration comprising:\n using a first energy source to compress air to a pressure above 200 bar; using a heat exchanger to absorb heat from said air above 200 bar; storing said absorbed heat in a latent heat storage medium; storing said compressed air in at least one storage vessel; expanding said compressed air from said storage vessel to provide expanded air for regeneration of energy; using a heat exchanger to provide heat to said expanded air from said heat storage medium; and generating power from said expanded and heated air.
