International Battery has received an $800,000 grant from the Pennsylvania Energy Development Authority (PEDA) to design, manufacture and test an 800 kilowatt-hour bulk energy storage system (BESS), expandable to one megawatt.
Marking International Battery’s largest battery system to date, the energy storage system aims to demonstrate the advantages of using large-format lithium batteries for renewable energy integration and Smart Grid support.
The storage system, which will accommodate International Battery’s large-format lithium batteries and battery management system (BMS), an inverter, as well as a control/communications system, will be housed in a 40-foot mobile container.
International Battery said it will join forces with an unnamed inverter company for this ambitious project.
The preliminary design work on the 800-kilowatt-hour system has begun and is expected to be ready for initial testing by 2Q11. The company plans to install the BESS unit to a selected site where it will be integrated with on-site renewable energy sources and the grid.
International Battery says the manufacturing process for its battery cells is inherently "green", because the cells are fabricated using a water-based process instead of the common use of large quantities of organic solvent chemicals.
The company is headquartered in Allentown, Pa. In May 2010, International Battery raised $35M in Series C financing.
