Osmotic power plant – Sounds like interesting technology. Just thought this might be useful to share with everyone.
———————
Norway opened on Tuesday the world’s first osmotic power plant, which produces emissions-free electricity by mixing fresh water and sea water through a special membrane.
State-owned utility Statkraft’s prototype plant, which for now will produce a tiny 2-4 kilowatts of power or enough to run a coffee machine, will enable Statkraft to test and develop the technology needed to drive down production costs.
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.
