dumb question, is it easy to redesign EV to use hydrogen? Isn't the whole premise of hydrogen being 1. world adopts renewable energy 2. to compensate for lulls, build way more capacity 3. excess capacity bought cheaply to create hydrogen ... 5. profit! for hydrogen vehicles anyway... seems like we're treading down on such path..

It wouldn't make sense for the current EV makers to switch to hydrogen. Tesla, for instance, has spent billions of dollars to optimize their battery packs with their lithium-based chemistry and specific cathodes/anodes. To then switch over to fuel cell + hydrogen is a completely different architecture, and Musk is notoriously anti-Hydrogen. There is a case to be made that excess renewables can be used to attempt to generate "green hydrogen" which is then a "storage" of renewables that can also be used for vehicles. I think in practice, it's a much smaller scale than battery electric vehicles.
