World Wide Wind and Uppsala University join forces to develop innovative offshore wind generator

NorthWind partner World Wide Wind AS and Uppsala University have been awarded a NOK 5 million grant to develop a novel direct drive generator that does not rely on rare earth elements for its permanent magnets.

The 30-month project will instead use ferrite, which is a more readily available material. The generator also features separate movement of the rotor and stator – a design that is both more compact and more efficient at converting mechanical input to electricity.

The CEO of World Wide Wind, Bjørn Simonsen, thinks these innovations will help ensure a wider adoption of floating offshore wind as a climate solution: “Europe needs floating offshore wind to reach the region’s energy and environmental goals, he says, and the floating offshore wind industry needs innovative solutions to improve their levelised cost of electricity. Our solution unlocks cost reductions along the entire value chain. Furthermore, by eliminating the need for rare-earth-elements, the turbines can be fully sourced and produced locally,”

The NOK 5 million grant was awarded by Eureka Eurostars through the Norwegian Research Council and Vinnova in Sweden.

World Wide Wind’s concept involves tilting, counter-rotating turbines. The generators will be situated below the water line, serving a dual purpose as both power generator and ballast.
