Norway's Statkraft opens first osmotic power plant
The world's first power project that generates energy by mixing fresh water with sea water has opened in Norway.
The Norwegian renewable power company Statkraft has built a prototype osmotic power plant on the Oslo fiord.
New Norway power plant uses salt to make electricityTOFTE, Norway — Norway unveiled the world's first osmotic power plant on Tuesday, harnessing the energy-unleashing encounter of freshwater and seawater to make clean electricity.
"While salt might not save the world alone, we believe osmotic power will be an important part of the global energy portfolio," the head of state-owned power group Statkraft, Baard Mikkelsen, told reporters.
Statkraft, which claims to be the biggest renewable energy company in Europe, is running the osmotic power plant prototype in a former chlorine factory on the banks of the Oslo fjord, about 60 kilometers (37 miles) south of the Norwegian capital.

The plant is driven by osmosis that naturally draws fresh water across a membrane and toward the seawater side. This creates higher pressure on the sea water side, driving a turbine and producing electricity.
Once new membrane "architecture" is solved, Statkraft believes the global production capacity for osmotic energy could amount to 1,600 to 1,700 terawatt hours annually, or about half of the European Union's total electricity demand.
