In the context of global climate change, the development of new renewable energy solutions is a major challenge . However, one avenue has so far remained relatively unexploited : osmotic energy. This is extracted, for example, from the differences in salinity between seawater and river water. It literally means converting the entropy of mixing associated with salt dilution into electricity.
Renewable and non-intermittent, it could be used in numerous locations around the world, generating up to the power equivalent of 1 000 to 2 000 nuclear reactors. However, the efficiency of osmosis-based systems has so far been rather mediocre, which has considerably hampered the development of this energy source, despite its many advantages.
