Unlike cars that run on fossil fuels, a hydrogen fuel cell electric car runs on two basic elements —oxygen and hydrogen. A fuel cell combines hydrogen and oxygen to produce electricity with heat, and water as by-products. Fuel cells are similar to batteries. They both convert the energy produced through a chemical reaction into usable electric power. Hydrogen fuel cell technology offers the advantages of a clean and renewable alternative energy source.
Environmental Impact
Cars powered by fossil fuel emit air pollutants that harm our environment by combining to produce smog and greenhouse gases. Fuel-cell electric vehicles are zero-emission vehicles. When a hydrogen fuel-cell electric vehicle operates, it emits only water. This means cleaner air, less global warming, and healthier, quieter neighborhoods.
Energy Supply
Hydrogen fuel can be produced using a wide variety of resource found in the U.S. Hydrogen is a renewable energy source and can be produced by waste, biomass, wind, solar, tidal, wave, and geothermal. Production technology includes steam reforming of natural gas, electrolysis of water, coal gasification, biological gasification, and thermochemical production. With all this resources hydrogen fuel can become a sustainable energy in an efficient and cost effective manner.
