Hydrogen is the lightest and most common of all elements. It can be used as a fuel for a modified internal combustion engine or a fuel cell. Hydrogen combustion produces only water vapour and small amounts of NOx as exhaust. Water can be split into its component parts, oxygen and hydrogen, by the use of electricity. This methodof producing hydrogen is known as electrolysis. Electrolysis uses more energy in the form of electricity than is produced in the form of hydrogen. Hydrogen, is however, a potentially useful method of "storing" electricity. The environmental impacts of using hydrogen as a fuel depend upon the source of the electricity used for electrolysis. If the electricity is generated from a coal fired power station, a hydrogen fuelled vehicle would result in larger emissions of CO2 and acid gases than a gasoline powered car. If renewable sources of electricity such as wind or solar energy (photovoltaic cells, or solar thermal power plants) are used, hydrogen vehicles would have no emissions of CO2 or other pollutants. Many people believe that solar produced hydrogen will be as widely used in the middle of the next century as petroleum is today

We need to find ways to get hydrogen from water that does not use more energy than the hydrogen will produce. I am sure this can be done but it seems that there really is very little funding for this kind of research.
