Latest Patents

Ishii holds a patent for a method of storing compressed air energy. This economical compressed air energy storage (CAES) method effectively utilizes the capacity of space in the air storage portion of CAES plants to reduce overall plant costs. The air storage portion is configured from multiple vessels, with a film that provides spaces with freely deformable shapes disposed within each vessel. During the air compression step, one side of the film is filled with a cushion gas, while air is stored on the other side. The cushion gas is transformed into a fluid with reduced volume to increase the amount of air stored. In the air expansion step, the fluid is heated and vaporized, decreasing the amount of air remaining on the other side of the film. Ishii's innovative approach has the potential to enhance the efficiency of energy storage systems.
