Countries and companies are now preparing and forming international coalitions to position themselves for the green hydrogen future.

    Making renewable energy reliable will require hydrogen as an energy storage mechanism. Except for a few special cases, 100% renewable grids are impossible without it.

      There are many chemosynthetic pathways to smooth intermittent supply from renewable energy sources. Electrolysis is only one of them.

      It certainly isn’t “impossible” without hydrogen.

        They all basically require hydrogen. E-fuels or green ammonia all require water electrolysis. Attempts at alternatives inevitable up trying to make crazy ideas work, like burning sodium or boron or whatever. Those ideas are pretty much all nonstarters.

      Definitely agree, at least if seeking a cost-effective solution.

      I expect an optimized clean electricity system would see renewables built to a ratio of hydro availability (35-50% of renewable production being hydro, depending on longitude, climate and storage investments), and the rest being some mix of nuclear, biomass & situational options (such as geothermal or regional interconnects).
