A hydrogen tank for a semi is going to weigh a lot less than the batteries for one, though. Hydrogen filling stations at truck stops are an easier problem to solve than ones at every corner gas station. You also solve the issue of having tens or hundreds of trucks at a truck stop trying to charge, and the nuclear reactors you would need to power it!
I think rooftop solar should basically be a requirement for warehouses over a certain size. I'm far from convinced the costs for individual houses makes much sense.
