    I think that’s only half the truth. Even if we have to convert our entire energy supply, we will still have to import hydrogen, at least in Europe. We have as much sun here as they do in Mordor. So there will be massive shipments of ammonia from the south to us. Forty per cent is therefore probably a little too high

        I think UK is blending it into their methane supply to reduce carbon emissions.

      What does hydrogen have to do with the Sun? You can produce the energy necessary for electrolisis from many other sources. Also there was a plan to make a hydroduct from France to Spain to transport green/pink hydrogen.

      Did you perhaps mean hydrocarbons (organic compounds used for fertilizer and fuel) instead of hydrogen (most common element in the universe, 2/3s the atoms and 1/9th the mass of water)

        We need sustainable energy storage, and hydrogen has few alternatives in this regard. However, the demand for green hydrogen can never be met by renewable energies in Europe. This means that it mainly comes from ships from sunny countries.

          Hydrogen is terrible for energy storage, and even worse for energy transport. Especially if you’re doing electrolysis to split water that you then re-generate with atmospheric oxygen in order to produce electricity. A battery, flywheel, or just pumping water upstream gets you far better efficiency, and shipping literally any product of a hydrogen reaction is likely to be more efficient than shipping a heavy H2 tank back and forth.

          Solar power in the EU seem to be increasing by 20% year-over-year. It’s hard to see a situation where shipping hydrogen to supply thermal energy to an existing factory would be cheaper than just building a local electrolysis plant and the necessary solar panels. (Unless, of course, you’re already invested or employed in selling hydrogen as a direct fossil fuel replacement.)
