    The entire premise of hydrogen is dumb.

    We would legitimately be better off combining it with CO2 to make synthetic gasoline and just use it with normal vehicles and infrastructure.

      Dude, that produces methane, I think?. The whole point is to avoid combustion engines to prevent greenhouse gasses.

      The way hydrogen is being used is to work with hydrogen fuel cells which is electric.

        Carbon is what matters, but not in the way the hydrogen-pushers want you to think:

        • It doesn’t matter if the fuel has carbon in it, if the carbon is part of the short-term carbon cycle. Biodiesel, for example, releases no net greenhouse gases even though it has lots of carbon in it.

        • The dirty secret of hydrogen is that the vast majority of it is made by cracking fossil methane. (My previous comment about combining hydrogen with carbon to make synthetic liquid fuel charitably presupposed it was made the right way, by electrolyzing water with solar power, but most hydrogen production is not like that)

        In other words, anybody telling you that hydrogen is better for preventing climate change than biofuels – despite them containing carbon – is trying to hoodwink you.
