    You’re completely ignoring the fact that it takes 3 to 5 times as much energy to actually drive a hydrogen car, because of the (in)efficiencies of the hydrogen production, supply and consumption chains.

    And given that the driving of a car is what consumes the most energy in its lifetime, the much higher efficiency of a BEV ‘pays off’ the higher production costs, both monetarily and ecologically.

      That’s just bullshit from BEV companies. At best, it’s something like 2x. At worse, it will take less energy, because you have waste energy from renewables. Wind and solar farms have a tendency to produce energy all-at-once, and shut down all-at-once too. You need massive amounts of energy storage to solve this. And the cheapest way of doing this is with hydrogen.

      So as a result, you just get a lot of super-cheap hydrogen that otherwise can’t be used. BEV don’t solve this problem at all, leading to a lot of wasted energy.

      Finally, fuel cells are also electrochemical systems, just like batteries. The notion that batteries will always be more efficient is just another lie from the BEV companies. In the long-run, this will be a unanimous win from fuel cells, because they will be equally efficient while also been much cheaper.

          Physics state that both are types of EVs. Both fuel cells and batteries are electrochemical systems. In fact, you can literally call a hydrogen fuel cell a hydrogen-air battery.

          So whoever comes out and say “but muh physics” has no idea what he’s talking about. If you really knew physics, you’d know that there’s holding back FCEVs in physics.
