ABSTRACT:
Bulk energy storage projects offer unique benefits over smaller distributed storage technologies. Primarily driven by the significantly lower relative costs achieved though economies of scale and the ability to store energy for tens of hours, bulk energy storage projects allow for energy storage to be deployed at the megawatt scale on transmission and distribution networks. Core bulk storage applications include firm renewable energy projects, network level integration of distributed PV generation, and no or low-carbon supply of ancillary services.

Compressed air energy storage (CAES) is one of two primary types of bulk energy storage , the other being pumped hydro, and store energy as compressed air in under or above ground vessels. General Compression is a Boston, USA based technology development company that has developed a near-isothermal compressed air energy storage system. Traditionally CAES projects have used natural gas to add heat to the generation portion of the process, General Compression's technology captures heat generated as electricity is converted to compressed air and reintroduces that heat during the generation process eliminating the need to burn natural gas making the technology fuel & emissions free.
