    Yeah, it is a ton of liquid, and I have no idea what the actual amounts look like vs actual uses for salt, such as water softeners (I use exclusively solar salt in mine). I have a hard time visualizing how much salt that actually is, and I haven’t looked up the numbers.

    Perhaps there’s an opportunity for at least one such facility?

      Well ya we could definitely use the excess energy to desalinize and then try and find a use for that one plant that handles over capacity. Millions of people rely on it for clean water, but today we mostly just dump it back into the ocean which causes problems and isn’t a long term solution.

      It’s just not a solution to the problem at scale, more like a band aid. But it could buy enough time to build more batteries.

      I mean if you pull the hydrogen, and are left with brine when the hydrogen is used it will release water, which effectively will get condensated and come back down as rain. Mostly ending up back in the oceans at the end of the day right? Wouldn’t that balance out the water to salt ratio at that point if the salt was just added back into the ocean? (Assuming it is dipersed over a longer area. Maybe even just making hydrogen powered ship motors that release the salt back into the water outflowing from the exhaust. Or is it that the chemicals wouldn’t form their original bonds, so you may have essentially drain cleaner left over when you are done with the electrolysis?

        These are two separate processes.

        You desalinate ocean water to produce fresh water, which you can use for crops, city utilities, etc. That reduces the strain on local aquifers and reservoirs, especially since California tends to overuse their supply of water (especially poignant for us in Utah; we all rely on the Colorado River).

        Hydrogen extraction tends to use pure freshwater to prevent corrosion during the electrolysis process. There has been some research around using seawater directly, but I’m guessing there’s still a fair amount of work yet to do this at scale, and I certainly don’t think we’re there yet for ships.

          Ah, I missed what you meant, was thinking just use the excess power as fuel for electrolysis to collect hydrogen tanks out at sea, then use that to store it for use in hydrogen based motors on ships or what not, letting the run off water go back into the ocean, hopefully leaving an equal amount of all elements in the water.

          But then thought of the bonds
