Agree with Shiner, fuel cells are way better than BEV's...but...
Hydrogen tank will always be an issue...until they figure out HOW2 manage liquid hydrogen. Bot at the generation/transport/storage/delivery and in-vehicle tank
Hydrogen in gaseous form will not have the range and/or the tank will be very large
Got laid off and my two skunk works teams at SunLabs, we were working on our invention...a solid state AC compressor with no moving parts, except for an automotive 1-way valve so the assembly would pump liquid nitrogen
Our target was super computing and super conductors in a cryogenic system. Fuel cells was at the bottom of the list
As the Program manager and inventor of some of that stuff, the heat to vaporize liquid hydrogen would be the passenger compartment AC system. Safety issues abounded as hydrogen in the cabin would not pass any safety requirements, but engineering is all about solving problems...
