The US Army has awarded a contract to C&D Technologies to develop an advanced energy storage system for renewable energy applications.

Under the $5m contract, the company will develop an energy storage system that will be used in grid-connected systems, off-grid applications, and micro-grid environments in conjunction with the army’s renewable energy generation systems.

The fully recyclable energy storage batteries of the system feature carbon nano-phase technologies, and will have enhanced cycling properties for effective wind and solar application.

C&D Technologies president Jeffrey Graves said the modular energy storage system with lead-carbon batteries will support Department of Defense initiatives to incorporate renewable energy generation sources into their grid and micro-grid systems.

Work under the three-year contract has already started at the company’s Blue Bell and Leola, Pennsylvania, facilities.

The contract was awarded by the US Army Research, Development and Engineering Command Contracting Center, Adelphi, Maryland.
