Rennes start-up Sweetch Energy is a branch of CNRS projects about osmotic energy. Kesako? Water always passes from the lowest concentrated medium to the most concentrated medium, for example salt. This is what causes the exchange of cells in our body. But extend this effect to large volumes of water, to estuaries, between the salty part of the freshwater river, and the sea, and you will recover energy. Either mechanically, by capturing the motion of water to rotate the turbines (low efficiency), or even directly electrical, by managing to capture the exchanges of ions (charged particles) between the two media , through specific membranes. With its osmotic power plant projects, Sweetch Energy can generate additional electrical energy. In France, the total potential will be 1.25 GW. But in countries in South America, on the Amazon River, the power supply can be more than 100 times higher.
