To paraphrase Mean Girls, “stop trying to make hydrogen happen.”

For some years now, detractors of battery electric vehicles have held up hydrogen as a clean fuel panacea. That sometimes refers to hydrogen combustion engines, but more often, it’s hydrogen fuel cell electric vehicles, or FCEVs. Both promise motoring with only water emitted from the vehicles’ exhausts. It’s just that hydrogen actually kinda sucks as a fuel, and automaker Stellantis announced today that it is ending the development of its light-, medium- and heavy-duty FCEVs, which were meant to go into production later this year.

Hydrogen’s main selling point is that it’s faster to fill a tank with the stuff than it is to recharge a lithium-ion battery. So it’s a seductive alternative that suggests a driver can keep all the convenience of their gasoline engine with none of the climate change-causing side effects.

But in reality, that’s pretty far from true.

    We’ll see.

    Once there’s enough hydrogen drilling and hydrogen production no longer depend on fossil fuel, then maybe H2 vehicules will make sense. Or maybe H2 will still be impractical due to other drawbacks.

    Meanwhile it make sense to focus on less polluting options.

      Theoretically one can slap a shit ton of solar panels to produce H2 with excess energy. Not very efficient, but still very green.
