Your system requires: * Air filtration * An air liquidation mechanism (cooling system + pressurization system) * A heat engine * Liquified air storage system * A turbine This is why exotic storage systems don't really pan out. Unless you already have 80% of the infrastructure already lying around (like in pumped hydro storage), you're better off buying batteries than buying the myriad of systems needed for some exotic energy storage system.
