The Toyota Mirai is a passenger vehicle, not an airplane nor a transatlantic container ship.

Sure, but if the economics of hydrogen motors worked out for planes and shipping, the argument is that it would also economically work out for cars.

  • Is suspect large trucks may eventually move to hydrogen, but smaller passenger vehicles will stay on batteries. The nature of hydrogen containment favors larger capacity, on account of better volume to surface area ratios.

    • Many jurisdictions require that commercial drivers take a 30 minute break every 4 hours. Those that don't should. Those stops make battery trucking feasible.

      And if you want to stop for 5 minutes instead of 30 you can use battery swapping solutions like the one Janus uses.

      Batteries are feasible for long distance trucking today.

      Green Hydrogen trucking uses 3X as much electricity as using it directly. Trucking's biggest expense is fuel, so that will be the killer factor ensuring battery will beat hydrogen for long distance trucking.

      They won't, why would they? The number of hydrogen gas stations is going down and the price is going up. Batteries are good enough already - the Mercedes eActros 600 with its 600 kWh battery has a range of 500 km.

    • I worked in one of the top 5 logistics companies in the world and I can recall them investing in electric trucks and charging infrastructure. Idea was to have strategically placed overhead lines that could recharge trucks without need for them to stop. Can't recall any mentions of hydrogen.

True, but it is a good first step. Start small, increment to larger solutions.
