The Islandsberg test site, locating off the coast of Lysekil in western Sweden, consists of 10 wave power units of which Fortum acquired two.

According to Fortum, the Islandsberg wave power units are based on a unique solution created at Uppsala University. The installations started in 2005 and when ready, the facility will consist of 10 units with a total effect of 100kW.

Goran Hult, head of hydropower at Fortum, said: Fortum already has one of the cleanest generation portfolios in Europe. Well over 80% of the electricity we produce does not cause any carbon dioxide emissions, but our aim is to improve this even further. Exploring and investing in promising new CO2-free energy production technologies, such as wave power, are part of this work.

Ander Hallberg, vice-chancellor at Uppsala University, said: Uppsala University is very pleased with the agreement. Energy is a strategic area of research and this agreement confirms that professor Mats Leijon’s research is world class.
