The Salinity Power project: Power production from the osmotic pressure difference between fresh water and sea water, Final Report

Project ID: ENK6-CT-2001-00504
Funded under: FP5-EESD


Salinity Power was the world�s first major research project focusing on the development of salinity (osmotic) power technology.
Salinity power uses membranes to generate power from the entropy difference between seawater and freshwater. This project made significant progress in membrane performance, the key component for competitive renewable energy production by this method.
Based on evaluation of the technical, environmental and economical features of the concept, Salinity Power concludes that a 200 TWh/a power generation potential exist in Europe.
The project has brought great interest around the world in this new, renewable energy source and establish the participants in this project as the world leaders in the development of salinity power.
The aim of the project was to evaluate the feasibility of commercial power production from the entropy change of mixing of fresh water and sea water. This was done through development and optimization of membranes and membrane modules suitable for pressure retarded osmosis.
The project made great progress in developing membranes especially designed for pressure retarded osmosis. Prototype membranes were developed, starting at an energy density of less than 0.1 W/m2. At the end of the project, an energy density of 1.7 W/m2 was verified for the best membrane. This represent a significant step toward the required power density for an commercial power plant.
A study of the environmental consequences, as well as the technical and economical potential for salinity power was completed to investigate possible "show stoppers". Today, no technological obstacles are identified that could prevent salinity power to become a huge, new renewable energy source.
The partners in the Salinity Power project were Statkraft (Norway), SINTEF (Norway), Forchungszentrum GKSS (Germany), Helsinki University of Technology (Finland) and ICTPOL Instituto de Ciência e Tecnologia de Polímeros (Portugal).
