    Yes we can. Electrolyzers need a certain water quality, thus if no surface or ground water is available, seawater desalination is the way to go, for example, dessert regions near the shores.

      Thank you, but does using this method effect the efficiency of an electrolyser?

        Yes, it does because desalination+electrolysis requires more energy imput than electrolysis alone.

    The installation of H2 systems and desalination systems should definitely take place together in the future.

    one should refrain from using pure drinking water to produce H2. I advocate either sewage, or even better, seawater.

    A salt water electrolysis is technically not a problem, you can condense it before the electrolysis in a CHP operation via the exhaust line and thus have desalinated drinking water or water for the electrolysis available. A desert state doesn’t need waste heat, so you can condense salt water.

      Thank you, it is really interesting idea and I believe market should start working on this ( as I have no idea is any company is already working for the same) as it could help create more sustainable energy and a possibility of connecting wave energy power generator with desalination plant and electrolyser can also prove to be cost effective. What are your views on this?

    This seems to be a logical progression in hydrogen production world wide. We should be producing hydrogen everywhere there is a surplus of water. Eventually, the marine sector should be supplied by coastal operations or by hydrogen produced off of floating wind farms.

      Yes floating wind and floating PV, both could prove to be a feasible option in my opinion.
