Yeah hydrogen is pipe dream. Hydrogen enbrittlement destroys it's containers and it leaks out between the atoms. If we could ever make bulk graphene that could contain it but very little progress on that front. As for producing the fuel it cost more energy to produce hydrogen than we get back burning it. Plus it is more explosive and dangerous to handle than current fossil fuels. Pretty much the only thing going for it is that it is clean if you don't ask where the energy to make it came from.
