Sweetch Energy

Sweetch Energy is building a carbon-neutral future by harnessing a natural and widely available resource, particularly in estuaries: osmotic energy. Sweetch Energy uses the difference in salinity between salt water and fresh water to create energy. 

The primary potential of osmotic energy lies in estuaries. The natural osmotic power in all the world's estuaries is around 1,300 GW. On a French scale (including overseas territories), the market potential is estimated at 30 TWh/year, or the equivalent of supplying electricity to more than 6 million homes. 

EDF Pulse Ventures invested in the company in 2023.

The development and use of low-carbon energies is at the heart of the EDF Group's raison d'être. By joining forces with a company like Sweetch Energy, EDF is helping to create a new renewable energy sector, strengthening its position as a low-carbon electricity producer.
