Abstract
An energy storage system includes a pneumatic vessel, a cable system attached to the vessel, a compressor for pressurizing the vessel, a generator attached to the cable system, a turboexpander generator for receiving compressed air from the vessel, and a control system. The system deflates and allows the vessel to sink in a body of water, inflates the vessel to store energy when an abundance of it exists, and allows the inflated vessel to resurface to release its buoyant energy to the generator via the cable system and to release compressed air to the turboexpander generator to generate electricity when electricity demand is high and/or electricity generation from other sources is low.
