This is a very poor analysis, since it doesn’t account for the capital costs. Even if hydrogen is inefficient compared to batteries, it could win if the upfront investment was low enough to offset the additional fuel cost. This is quite obvious, since that’s why diesel trucks are winning today — the upfront cost of a diesel engine is cheap enough that it offsets the higher lifetime fuel costs.

I do think that batteries will win, but the correct argument is one that shows that capital costs of batteries are going down faster than the cost of hydrogen production.
