The two links provided contain information about hydrogen as a combustion fuel and also as a component for fuel cells.
Many people ask what the difference is between our use of hydrogen and fuel cells. The difference is that fuel cells recombine oxygen and hydrogen within the cell. When the oxygen and hydrogen recombine into water, energy is produced. Although fuel cells, at the same capacity of petroleum fuels, could get 3x the efficiency, the cost and weight issues work heavily against its applicability in transportation settings. Further information can be found in the link provided.
For our project, we are merely using hydrogen as an energy carrier. Hydrogen is NOT a source of energy. We are storing energy in the form of hydrogen rather than batteries because hydrogen is completely clean, and as long as we keep impurities out of our ovonics canisters, we can use the tanks far longer than we can use batteries.
