Then if Hydrogen is available at many fuelling stations how hard would it be to convert classic cars to run on Hydrogen. Then car nuts could own an efficient daily driver car that use a fuel cell and an electric motor but if they want also own a classic an occasionally use it running on Hydrogen with less nasty gases than petrol coming out the exhaust.
Burning hydrogen in an ICE is quite a different matter from a fuel cell though. I can imagine this would be a flippin' expensive proposition.
Though hydrogen fuel cells are a clever solution to the long range use of vehicles, I'm still struggling to see the appeal for people like me.
Once I have all the kit installed I can make electricity for nothing at home, use it to provide for a very large proportion of all my domestic electricity use and store it in my powerwall / BEV at no cost. I can also make money from the equipment by selling my excess generated power back to the grid.
The cost of the domestic solar PV array + the cost of a BEV (Kia e-Nero is around £35k, 10KW solar array + powerwall say £30k) is broadly the same as buying an HFC vehicle (Toyota Mirai £65k). My electricity provider gives me free on the road charging at its network of chargers.
Filling up an HFC is broadly the same cost at the moment as filling up an ICE car in terms of pence/mile, so that's an extra cost on top.
So from my perspective one would be spending quite a lot of money and losing quite a lot of benefit to solve the range problem, where the alternative is simply to do a bit of forward planning when making infrequent long journeys.
