A Renewable or Nonrenewable Energy Type
In an effort to reduce the amount of crude oil used in the United States, a government program was started in 2002 to examine the use of hydrogen as a transportation fuel. In this application, hydrogen is used in a fuel cell vehicle to produce electricity. This allows a vehicle to enjoy the higher energy efficiency of a battery versus a gasoline-powered vehicle, while avoiding the frequent and long charging times needed for an electric vehicle. There are currently other applications for hydrogen in the United States and the world, primarily in refineries and the manufacture of ammonia. Unlike fossil fuels, such as coal, natural gas, and crude oil, there are no natural sources of hydrogen gas. There are several options for producing hydrogen, such as reforming natural gas or gasifying coal or biomass. Alternatively, a renewable energy source, such as wind or solar, could be used to produce hydrogen via water electrolysis.
