A U.S. developer and manufacturer of large-format lithium-ion rechargeable batteries and energy storage systems says it has received an $800,000 grant from the Pennsylvania Energy Development Authority (PEDA) to design, manufacture and test an 800 kWh bulk energy storage system expandable to one megawatt. The grant is part of PEDA’s mission to promote development and use of Pennsylvania’s clean, indigenous energy resources, and stimulate economic development and job creation for Pennsylvania’s growing energy sector in an environmentally beneficial manner.
Marking International Battery’s largest battery system to date, the completed energy storage device will demonstrate the advantages of using large-format lithium batteries for renewable energy integration and Smart Grid support.
The storage system, which will accommodate the developer’s large-format lithium batteries and battery management system (BMS), an inverter, as well as a control and communications system. These will be housed in a 40-ft mobile container. International Battery will join forces with an inverter company for this project.
The preliminary design work on the 800-kWh unit has begun and may be ready for initial testing by the Q2 2011. 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.
A factor in the company’s development of its energy storage systems is its aqueous manufacturing process that is inherently green. The battery cells are fabricated using a water-based process instead of the common use of large quantities of organic solvent chemicals.
