Many of the technologies being developed today for HEVs will contribute to the development of hydrogen-powered fuel cell vehicles in the future. Research and development sponsored by the U.S. Department of Energy, FreedomCAR and Vehicle Technologies Program, is leading to a comprehensive suite of new technologies, including advanced combustion systems, advanced fuels, and overall vehicle systems, as well as hybridized components such as electric motors, energy storage systems, power electronics, and lightweight materials. Many of these innovative technologies are already in vehicles or soon will be. U.S. Dept. of Energy
