You say, "Hydrogen is a brilliant fuel source." But in fact, it is not a "fuel source." It is a carrier of energy—a very clean carrier, like electricity. To obtain hydrogen, you need to do something using fuel to make it. Most of the hydrogen in our industrial economy is made from natural gas, a gaseous "hydro" carbon. Or, using grid electricity (made mostly from natural gas and nuclear), you can get hydrogen gas. I recall those basic chemistry demonstrations taking an aluminum strip and placing it in acid, inverting a test tube over the bubbles coming from the liquid, and capturing hydrogen, which we'd burn with a quick "pop" out the end of the test tube. That would have been chemically produced hydrogen, the result of acidification of aluminum. 2 moles of aluminum with 3 moles of water in an acid produces a residue of 1 mole of aluminum oxide plus 3 moles of hydrogen. It's a pretty expensive way to get it, but it's easy if you only want ambient hydrogen for the demo.
Hydrogen is waaayyy too expensive ever to make it in the real world as we know it today.
