The site in Fukuoka is only the second power plant of its type in the world, harnessing the power of osmosis to run a desalination plant in the city

    I don’t know, so I can only guess.

    The desalination plant could have been there already, because for whatever reason it was more practical (or even required) than taking the water from the river.

    Or maybe the desalination plant requires very little power, maybe less than what the osmotic plant produces.

    Or the whole thing is indeed energy negative, but not as energy negative as having just the desalination plant. So at least they get to use the brine from the desalination to recoup some of the energy. Because the osmotic plant is power positive.

      Something stinks here and it’s not the treated sewage.

      I think the idea is that if you have an unlimited supply of treated waste water, and a limited supply of fresh water and an unlimited supply of pumps and osmotic membrane and turbines you can harvest energy from the process you already need?

      IDK… calling it a power plant seems like the stretch. But I’m not a languager.
