Statkraft osmotic power prototype in Hurum
Encyclopedia
Statkraft osmotic power prototype is the worlds first osmotic power plant, based on energy of osmosis
. The power plant is run by Statkraft
. The power plant is located at Tofte in Hurum
, Norway
, with rooms at the factory area at Södra Cell Tofte
cellulosis factory. The power plant uses osmosis that appear, when fresh water and sea/salt water meets, separated by a membrane. The salt water pulls fresh water through the membrane and the pressure increase in the salt water side, can be used to produce electrical power.
The plant is a prototype developed together with Sintef
and began test power production 24. November 2009.

made the official plant opening. This plant had been planned since summer 2008, with a water usage of 10 liter fresh water and 20 liter salt water per second. It is expected a power of 2-4 kW
. With better membranes it is assumed that the power for a similar plant can be increased to ca. 10 kW. A commercial start is expected between 2012 and 2015.
