Hydrogen (H2) will play an important role in developing sustainable transportation in the United States, because in the future it may be produced in virtually unlimited quantities using renewable resources. Hydrogen has been used effectively in a number of internal combustion engine vehicles as pure hydrogen mixed with natural gas. In addition, hydrogen is used in a growing number of demonstration fuel cell vehicles.
Fuel cell vehicles use electricity produced from an electrochemical reaction that takes place when hydrogen and oxygen are combined in the fuel cell “stack.” The production of electricity using fuel cells takes place without combustion or pollution and leaves only two byproducts: heat and water.
