Hydrogen vs. Battery Electric Cars

I think some of your reasoning is flawed you sad self the eficiency for hydrogen is much worse and it is hard to improve so this means you will need a lot more energy if everyone went to hydrogen cars so the grid would fail even harder than if everyone charge there electric car overnight. Also with solar panels you can make your owne fuel for bev and diversity is nice fore a short while but if the grid is down you can't make and store any more hydrogen so it can be only usefull if the grid is down for a short while. One last point on refueling and range a 5 min refuel time is nice but with long range bev you can drive for 2-3 hours and then refuel for 30 min and then do it over again this seams long but if you grab something to eat or drink these 30 min can be filled rapidly and most people need a brake after 2+ hour drive anyway to strech your legs ... so overal i think bev are the future much more than hev mainly because of efficiency and even with trucking transport a bev will make much more sense in a few years because of increased energy densisty in battery's, so investments in the technology right now seems like a waste to mee it would be a nice transition from ice to bev but bev took off much earlier than hev
