The value proposition of hydrogen is energy density. Batteries have low energy per unit of volume and awful energy density by unit of mass. You will never, ever, fly across the Pacific on a battery powered aircraft. Transoceanic shipping is also not feasible with batteries (current and proposed battery powered shopping lanes are short hops of a couple hundred kilometers or less).
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.

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