The promise of osmotic energy

Osmotic energy opens up new perspectives in the field of renewable energies. This innovative technology exploits the difference in salinity between fresh and salt water to produce clean, sustainable electricity.

Operating principle

The process relies on the osmotic pressure created when two solutions of different salinity are separated by a semi-permeable membrane. Fresh water flows naturally through the membrane towards the salt water, generating pressure. This pressure can be converted into electricity via a turbine.

Existing installations

Several osmotic energy pilot projects have been launched around the world. In Norway, an experimental power plant is using autonomous systems to optimize production. In the Netherlands, osmotic micro-generators are being tested in a river estuary.

Development potential

Osmotic energy has great growth potential. Technological advances in membranes and autonomous systems offer the prospect of increased yields. The integration of micro-generators could make it possible to exploit smaller sources of brackish water.
