Hydrogen+Fuel+Cells


 * HYDROGEN FUEL CELLS** ~

The element Hydrogen itself, is an energy carrier and needs to be produced from another substance. It can be produced from a variety of resources such as water, fossil fuels and biomass and what more, is a byproduct of other chemical processes. The two most common methods for obtaining hydrogen are steam reforming and electrolysis. Some bacteria and algae also produce hydrogen.  1)  __ Steam Reforming __ is used to separate hydrogen atoms from carbon atoms in methane molecules. It is the least inexpensive method of producing hydrogen. However, due to the fact that methane, is indeed a fossil fuel, the process of steam reforming creates greenhouse gas emissions.      2) __Electrolysis__  is used to split hydrogen atoms from water. It is rather expensive, however creates no emissions.

Hydrogen can also be found in hydrogen batteries, called __Fuel Cells__. A main use of these fuel cells are by The National Aeronautics and Space Administration (NASA), in their space ships. Liquid hydrogen fuel lifts the space shuttle into orbit. Fuel cells power the shuttle’s electrical systems. The only by-product is pure water, which the crew uses as drinking water. Hydrogen fuel cells make electricity. They are very efficient, but expensive to build. Small fuel cells can power electric cars, while large ones can provide electricity in out of the way places with no power lines.
