I mostly agree with you but not entirely. I do think there’s a feasible path to hydrogen being useful in several applications. I don’t think cars are good, but airplanes, trains, and trucks are bigger possibilities.

I do think to make sense we would have to do thermochemical cogeneration with nuclear power plants. This has the nice benefit of significantly increasing the overall efficiency of the nuclear power plants, increasing overall efficiency from the 33% realm to around 50% with cogeneration seems possible, and that use of waste energy helps to offset the worse efficiency downstream. Combined with applications where the weight of batteries is problematic, and you have some potential for success
