$15,000 worth of fuel card sounds generous until you find that hydrogen stations have jacked up prices to $36/kg.

still means nothing, what is the mileage or $/mi there?

    Apparently 1kg of hydrogen is about 60 miles range, which seems like a lot, but apparently fuel cells are that good.

    Currently hydrogen fuel if you can get it is about 15 quid a kilo in the UK, giving a tank range of around 400 miles for £80. This makes it a little more expensive than diesel, considerably more expensive than petrol, and roughly the same price as electric.

    By comparison Autogas LPG is around 92p/litre (or about £1.80 per kilo) and in a very large heavy 4.6 litre Range Rover you get around 250-300 miles for your £80 tankful, depending on how heavy your right foot is.

      Is electric charging more expensive in the UK than petrol? That's nuts.

      If you can get a cheap electric overnight home charging tariff in the UK, then the electric cost is lower. Mid week, I charged 43kWh for the cost of £3.04 (7p per kWh). My home charger does 7kwh in a hour. Usual mileage is about 4 miles per kWh (typical rush hour drive into Edinburgh). That should give me about 170 miles of range.

      Scaling it to 400 miles (400 miles at 4 miles per kWh is 100 kWh which at 7p each is about £7. Pretty much an order of magnitude better than your estimate. I admit home charging is the best arrangement and I am fortunate to have it. I did a holiday trip to the highlands and used public/hotel chargers which were closer to your numbers but also much faster (up to 150kWh per hour capacity).

      I think that even discounting hydrogen engineering difficulties, the infrastructure for electric is pretty much in place and the race of the technologies is over.
