If you mix salt water with fresh water you create instant carbon-neutral energy – the process is called osmotic power and the world’s first osmotic power plant has just opened in Norway. The plant, founded by a company called Statkraft, will operate modestly during the testing stage but hopes to generate significant energy sources progressively. “For now the plant has a limited production capacity and will focus mainly on testing and developing the technology for commercial application. When osmotic power does go commercial, it could make a significant contribution to a sustainable, carbon neutral energy future. The company estimates that the global potential of osmotic power is equivalent to half of the European Union’s current energy production…. Aside from the obvious mixing of seawater with river water and other natural freshwater sources, osmotic power can also tap the latent power in other water sources, such as desalination plants and wastewater treatment plants.”
