I remember back during the 2008 oil crisis, I was on a forum where we were talking about energy and the alternatives to oil and the consensus was that hydrogen was a lot less efficient than batteries. You had to store the hydrogen in compressed cylinders, it's flammable, you need expensive catalysts in fuel cells to transform it, though hydrogen is light, it takes a lot of volume to store it because it doesn't compress very well, refueling is complicated. There are also losses at every step of the energy pipeline: electrolysis, pipelining, compressing, decompressing, running it through fuel cells ,etc. It's much more efficient and less complicated to just use electricity and batteries.
