Clean Vehicles, Clean Fuels, Clean Air, Clean Cities!


hydrogenHydrogen (H2), when used to generate electricity through a fuel cell, is an emissions-free alternative fuel that can be produced from diverse domestic energy sources. Research and commercial efforts are under way to build the hydrogen fueling infrastructure and produce hydrogen fuel cell electric vehicles that are practical for widespread use.

Hydrogen has been used effectively in a number of internal combustion engine vehicles as pure hydrogen or mixed with natural gas and in a growing number of demonstration fuel cell vehicles. Hydrogen and oxygen from air fed into a proton exchange membrane fuel cell stack produces electricity to power an electric automobile without producing harmful emissions.

Fuel cell electric vehicles, also known as FCEVs, are powered by hydrogen and have the potential to revolutionize our transportation system. They are more efficient than conventional internal combustion engine vehicles and produce no harmful tailpipe exhaust—they emit water vapor and warm air. Fuel cell electric vehicles and the hydrogen infrastructure to fuel them are in an early stage of deployment.
