Osmosis is a natural phenomenon occurring between two solutions of different concentrations (for example saltwater and pure water) separated by a membrane. A flow of water is naturally induced from the low to the high concentration solution, which tends to equilibrate the concentrations on each side of the membrane. The mechanical energy of this flow can be converted into electrical energy using a turbine.

This approach is called Pressure Retarded Osmosis (PRO). PRO is a very promising technique, but current systems based on PRO are limited in the amount of power generated, which compromises their commercial viability.

OsmoBlue overcomes the current limitations of PRO using a simple and novel approach. Taking advantage of its expertise in technology, materials, and fluidics the OsmoBlue team is addressing the technical limitations of PRO with innovative solutions.

The patented OsmoBlue technology constitutes a real breakthrough, providing higher power density than current PRO systems. Moreover, unlike many existing osmosis-based technologies, OsmoBlue technology will transform low-temperature heat (as low as 30°C) into electricity.
