Hydrogen is powered through fuel cells. The hydrogen is stimulated by the electrode anode and transforms into ions. The hydrogen ions pass through electrolyte membranes, where they are combined with electrons and oxygen to produce water, heat and electricity.

Electric currents are used to separate water into base elements of oxygen and hydrogen. Hydrogen is only found with other molecules, and it must always be separated for energy use. Hydrogen is also found in organic compounds, including hydrocarbons. It is mostly made from natural gas, and it is extracted from hydrocarbons by a method of heating known as reforming. Other fuels such as gasoline and methanol can be reformed to produce hydrogen. Fuel cells benefit most from pure hydrogen. The fuel cell constantly charges with the help of hydrogen. Because it is everlasting, experts believe that renewable energy sources can produce hydrogen and energy that can be stored for later use.

Fuel station hydrogen is compressed for dispensing into cars, trucks and forklifts. Fuel cells are placed within a stack to power motor vehicles. Stacks that contain more fuel cells produce more of a charge. The fuel cells also create electricity in rural areas, with no need for power lines. Hydrogen provides heat and power to buildings.
