I really doubt it. Hydrogen is explosive and extremely hard to contain. It also burns too hot and too fast for regular engines. It's basically a bad fuel all around. If it was any good we would be using it for heat instead of natural gas. If we're producing chemical fuel on a large scale, hydrocarbons are a nearly perfect form. More likely, some kind of battery breakthrough will replace lithium ion. We only need 3-5x current power density to replace fuel for most uses. Lithium ion was about 3x better than NiCad when it came out. If we can repeat that just once more, there will be a battery revolution
