      Green/grey/blue/whatever refers to the production process and the energy sources used to make the hydrogen, because the production and powering it with electricity also requires emitting greenhouse gases. Most of the hydrogen produced today is gray hydrogen produced using fossil fuels. I don’t understand why we hear so much about hydrogen as being the fuel of the future, when straight electrification would be more efficient, but maybe I’m missing something.

        For some things hydrogen doesn’t really make sense, but for everything else it’s basically a form of a battery. The one big advantage it has over batteries is its weight.

      Is there bad hydrogen? 🤔

      The Hindenburg would have some things to say about this…

        To be fair, it wasn’t designed for hydrogen, but helium.

        It’s like putting diesel into a petrol engine (or vice versa), and saying petrol is bad when the engine inevitably explodes.

      Yup. Green hydrogen comes from splitting water with electricity from renewables.

      Other flavours of hydrogen come from splitting natural gas, using electricity from burning stuff. Which isn’t as green.
