    Something else no one has said yet (I think) is that most hydrogen is produced from natural gas, so this is in no way a climate solution. It’s been sold as one and it’s bullshit.

      While producing hydrogen from natural gas is cheaper, this company claims to produce it with electrolysis

      But IMHO at the moment is a waste of energy

      Yes but not for long.

      As (generally climate denying) people love to point out, wind and solar is erratic power generation. For this reason you need triple capacity Vs requirements.

      This means that for a huge amount of time you’ll have excess energy, once we start to be predominantly renewables, battery storage is expensive. One of the solutions is to create hydrogen, also pumped hydrogen, etc.

          That is irrelevant to the topic.

          The reason why hydrogen is produced by steam reforming is because natural gas is cheap and is needed to produce ammonia. In Norway where there is plenty of cheap electricity from hydroelectric, there is hydrogen production via electrolysis.

          The advantage of hydrogen as fuel is that can be used to decarbonise things like ships, and possibly things like branch rail lines, and planes. Passenger vehicle is probably the least attractive application, but somewhat lower capital investment than a green hydrogen plant on a industrial scale.

          However this can only make sense if electricity is cheap i.e. if they are running with waste electricity from renewables.

        Okay but you have to use electricity to do that and currently you’re generating carbon by producing the electricity.

        It’s not a solution.
