The 10-kilowatt capacity plant, located at Tofte, near Oslo, will use a two-chamber system in which freshwater and seawater are mixed through a semi-permeable membrane to generate pressure-driven electricity.
Statkraft has been developing concept, known as pressure retarded osmosis for some 10 years in collaboration with Norwegian research and development group SINTEF.
"This new technology generates electricity simply by mixing water. New solutions to meet the climate challenges might be closer than we expect, which makes me confident that the future looks bright," says Statkraft chief executive Bård Mikkelsen.
