In an osmotic power plant, we feed freshwater and seawater into two chambers, separated by a membrane. The salt in the seawater then draws the freshwater through the membrane, causing the pressure on the seawater side to increase. This pressure corresponds to a water column of 120 metres, similar to a large waterfall, and can be utilized in a turbine to generate electricity. Osmotic power plants can be constructed anywhere freshwater flows out into the sea, provided that the salt concentration is sufficiently high.

CONT

Fonctionnement d'une centrale osmotique. Lorsqu'on sépare de l'eau douce et de l'eau salée avec une membrane semi-perméable, l'eau douce migre par osmose vers l'eau salée, ce qui augmente la pression du côté de l'eau salée. C'est la pression osmotique. Elle sert à faire tourner une turbine.
