A hydrogen internal combustion engine (ICE) vehicle uses a traditional ICE that has been modified to use hydrogen fuel. The U.S. Department of Energy’s FreedomCAR and Vehicle Technologies Program has identified hydrogen-powered ICE vehicles as an important mid-term technology on the path to the hydrogen economy.
The Advanced Vehicle Testing Activity has teamed with Pinnacle West (holding company of Arizona Public Service) and Electric Transportation Applications to construct and operate a hydrogen/CNG generation and fueling facility in Phoenix, Arizona. The facility provides pure hydrogen, pure CNG, or hydrogen/CNG blends to the various internal combustion engine test vehicles. Information about the Hydrogen/CNG Pilot Plant Design is available along with a fact sheet.
