Enova Builds First US Air Force Fuel Cell Bus

December 10, 2003 by Jeff Shepard

Enova Systems Inc. (Torrance, CA), a developer and manufacturer of mobile and stationary electric, hybrid and fuel cell digital power management systems, announced that it has successfully integrated a fuel cell system into the US Air Force's first hybrid fuel cell bus at Enova's facilities in Honolulu, HI.

The US Air Force's first battery-dominant, fuel cell hybrid bus, passing final acceptance tests with flying colors, was completed through a teaming effort between Enova, the US Air Force, the State of Hawaii's High Technology Development Corporation and Hydrogenics Corp. Enova provides the enabling technologies to convert fuel cell energy into useable power for propulsion and operation of the Air Force bus. Enova's technologies optimize the hybrid fuel cell bus by requiring a reduced fuel cell power module size through the introduction of a battery pack and the ability to capture "regeneration" energy from braking, which is transferred back to the batteries.
