to split water molecules to create pure hydrogen and oxygen. One big advantage of this process is that it can be done anywhere. For example, you could have a box in your garage producing hydrogen from tap water, and you could fuel your car with that hydrogen. Reforming fossil fuels; Oil and natural gas contain hydrocarbons (molecules consisting of hydrogen and carbon). Using a device called a fuel processor or a reformer, you can split the hydrogen off the carbon in a hydrocarbon relatively easily and then use the hydrogen. You discard the leftover carbon to the atmosphere as carbon dioxide.
             The second option is slightly odd. You are using fossil fuel as the source of hydrogen for the hydrogen economy. This approach reduces air pollution, but it doesn't solve either the greenhouse gas problem, because there is still carbon going into the atmosphere. However, it may be a good temporary step to take. Gasoline is an easily available source of hydrogen. Until there are hydrogen stations on every corner like we have gas stations now, this is the easiest way to obtain hydrogen to power a vehicle's fuel cell.
             Where will the electricity for the electrolysis of water come from? Right now, about sixty-eight percent of the electricity produced in the United States comes from coal or natural gas.
             Right now there are several different ways to create electricity that do not use fossil fuels: nuclear power, hydroelectric dams, solar cells, wind turbines, geothermal power, wave, and tidal power. In the United States, about twenty percent of the power currently comes from nuclear
             and seven percent comes from hydroelectric. Solar, wind, geothermal and other sources generate only 5 percent of the power (Renewable 1).
             The electrical-generation problem is probably the biggest barrier to the hydrogen car. Onc
