Sweetch Energy .
Presenting Company
Sweetch Energy harnesses osmotic power—energy generated from the natural mixing of fresh and salt water—using cutting-edge nano-osmotic diffusion (INOD) membranes developed in partnership with CNRS. This breakthrough enables the production of 24/7 flexible, renewable, and dispatchable electricity without carbon emissions. The modular system, powered by ion exchange membranes, delivers competitive electricity at $90–120/MWh, suited for baseload and peak demand. With applications in estuaries and industrial settings, Sweetch’s technology can potentially meet up to 15% of global electricity needs. After launching a pilot plant in France, the company is scaling globally with a target of 1 GW+ post-2030.
