Hydrogen as fuel is just an energy transport material anyway.

Getting the hydrogen, which exists around us everywhere in abundance, is the hard part. Making pure H2 requires energy, even though it's right here, no digging required. Electrolysis is a common way to produce it, but then the question becomes, where did the electricity come from to break down the water? And then the same question about the provenance of the energy transport "material" of electricity? (I know it's not a material...).

Wind, solar, hydro? Those sources don't (materially, material, ha!) to an increase of CO2 emissions. But what if it's a coal fired power plant that generates the electricity that decomposes the water that produces the hydrogen that is burned to move the truck? Not as carbon-neutral now, is it?
