That’s not entirely true. If you are purely looking at $/kWh then yes, of course this is the case. However that is not the only consideration when it comes to transport. Weight of the drive unit, use of rare earth metals, lifespan of the drive unit, energy density by weight, speed of recharge, ease of transport energy, and more are all considerations.
I’m not arguing that vehicles will become hydrogen electric. I agree they are not suitable without some serious technological advances. What I’m saying is that at a certain point, larger vehicles (trucks, trains, ships, even aeroplanes) will become more suitable to hydrogen.
