Design, build, and deploy a utility-scale, low-cost compressed air energy storage system to support the integration of renewable energy sources onto the grid beginning in 2010. The 1 MW/4hr system will store potential energy in the form of compressed air in above-ground industrial pressure facilities. The technology utilizes isothermal gas cycling coupled with staged hydraulic compression and expansion to deliver an efficient and cost-effective energy storage solution.
-Electricity costs reduced
-Grid efficiency improved
-Renewable energy source use accelerated
-Greenhouse gas emissions reduced
