<p>In some embodiments, systems are provided in which electric power generated from a renewable energy source such as a solar or wind power system during low demand periods is used to drive an electric motor which turns an air hybrid split-cycle engine. The split-cycle engine operates in AC mode during this time to compress air into a storage tank. Later, during high demand periods, compressed air stored in the tank and added fuel are fed to the split-cycle engine, which operates in AEF mode. The work generated by the split-cycle engine turns a generator to produce electric power. When the supply of compressed air stored in the storage tank is depleted, the split-cycle engine can operate in an NF mode to serve as a backup generator, or in an FC mode to serve as a backup generator while simultaneously recharging the air storage tank.</p> |
