Osmotic power, you say? That's exactly what brings the juice in one of Norway's Statkraft plants, which opened yesterday. According to the company, the plant generates electricity thanks to a bank of cells that force osmosis:
"The plant generates power by exploiting the energy available when fresh water and seawater are mixed. Osmotic power is a renewable and emissions-free energy source that Statkraft has been researching into for 10 years and that will be capable of making a substantial global contribution to eco-friendly power production."
It looks like the technology stills needs a bit of time to mature, though, according to Statkraft, "the global potential of osmotic power is estimated to be 1,600-1,700 TWh per annum, equivalent to 50 percent of the EU's total power production," and plants can be installed anywhere where fresh water streams into the sea.
Will it save the world's energy crisis? Probably not — at least, not yet. It is another option, though, for clean, renewable energy.
