  1. In 2026, Norwegian startup Flocean is slated to launch the world’s first demonstrator and commercial-scale subsea desalination plant at Mongstad, Norway.

    By moving operations to the ocean floor, the company addresses the high costs, environmental damage, and energy intensity associated with standard land-based desalination facilities.

    Flocean’s technology operates at depths of 300–600 meters to make seawater drinkable. This location provides a fundamental engineering advantage.

    Dont you have to put the energy back in when you bring it the surface? The membrane rely on a pressure difference.
