SDG 11: Sustainable Cities and Communities

Nano tech could get zero-carbon energy from sea water

A view of an industrial estate at Tofte near Oslo, Norway, March 2, 2008, where state power group Statkraft will build an experimental "salt power" plant in 2008. The tiny plant will generate energy by mixing salt water in the sea with fresh water from a stream, exploiting the natural energy found in osmosis -- the process used by trees to suck water from their roots to their leaves.

To date, large-scale blue energy projects such as Norway’s Statkraft power plant have been impeded by the poor efficiency of existing membrane technology. Image: REUTERS/Alister Doyle
