As you know, from an emissions standpoint, hydrogen is one of the cleanest fuels available. Unfortunately, our most abundant source is water, and with current technology, breaking those two H atoms away from that one O atom (electrolysis) uses more energy that it creates. H2Gen claims its process is as much as six times more efficient than conventional electrolysis.
Now let's hope automakers' hydrogen programs, like BMW's test of its Hydrogen 7, work out. Then stand back and watch gasoline-powered cars go the way of the dinosaurs.
