I doubt it, much less a problem than with desalination, volume wise.

  The volumes are huge. Each hydrogen molecule needs one water to break down. That adds up at industrial scale.

    The volumes are tiny compared to desalination. Freshwater is worth much less than hydrogen.

      I cant seem to edit the parent comment but you are indeed correct. I thought the water usage was high because I was looking at local water usage from planned hydrogen production compared to human usage, but most of the hydrogen will be exported, so globally it averages out to a small amount that is very significant locally.

    The hydrogen equivalent of 1 liter of gasoline requires 0.16 liters of water. So enough fuel to drive a sedan about 300 miles requires roughly the same amount of water as an adult male consumes per day.

      Exactly, which is nothing compared to how much water a human uses per day for other purposes. The volume is so small here.
