Bright Energy Storage Technologies and the Engines and Energy Conversion Laboratory at Colorado State University propose to demonstrate the feasibility of a custom reversible compressor design for use in compressed air energy storage systems. The design proposed combines a very lightweight rotary compressor design with extremely high flow volumes, allowing a highly efficient device at extremely low cost, about an order of magnitude less expensive than the separate compressor/expander systems currently used in compressed air energy storage systems.
