Rochester Hills, Michigan [RenewableEnergyAccess.com] Energy Conversion Devices, Inc. (ECD Ovonics) received a contract of approximately $1.8 million to develop and demonstrate a hydrogen-powered airport tow tractor and to further develop its Ovonic metal hydride fuel cell technology.The project is for the U.S. Army’s Tank Automotive Research, Development and Engineering Center (TARDEC) via its National Automotive Center (NAC). ECD Ovonics will develop and demonstrate a high-efficiency, ultra-low emissions, hydrogen hybrid-electric internal combustion engine powered aircraft tow tractor that uses onboard Ovonic solid hydrogen storage systems. ECD Ovonics will also further develop its non-noble metal hydride fuel cell stack technology, which provides instant start, good low-temperature performance and intrinsic energy storage. The contract will be administered by Aerospace Engineering Spectrum (AES), based in Ogden, Utah, via a subcontract to ECD Ovonics on behalf of Ovonic Hydrogen Systems and Ovonic Fuel Cell Company. AES will provide project management services through its prime contract with the Department of Defense under the Design Engineering Support Program.
