Abstract
An offshore compressed air energy storage system has a barge comprising with a deck, and at least one pressure vessel configured to store compressed air. A power source powers at least one air compressor configured to pressurize the pressure vessel. A compander set has at least one turboexpander having an input, an output, and a shaft, as well as at least one heat exchanger and at least one turbocompressor. A mass air control valve is configured to control the compressed air flow from the pressure vessel to the turboexpander. A generator is in communication with the shaft of the turboexpander, and a control system. The at least one pressure vessel is buoyant, and wherein the at least one air compressor, the turboexpander, the mass air control valve, and the generator are attached to the barge.
