Hydrogen and Fuel Cells


Hydrogen makes up 90 percent of the universe by weight.  It is usually found in combination with other elements.  When purified and used as a fuel (in mobile and stationary applications), hydrogen does not produce any harmful emissions to the environment.  The U.S. Department of Energy is working together with industry, national laboratories and academia for the development of hydrogen technologies. 

Fuel cells

Fuel cells harness the chemical energy of hydrogen to generate electricity without combustion or pollution. Water is the only by-product that is emitted from the process, which makes it an attractive alternative form of energy.  The vehicles are propelled by electric motors that use of onboard fuel cells.
