Generating global impact

GreenSpur Renewables Ltd.

Direct drive generators are becoming an increasingly vital part of offshore wind energy, with operators shying away from unreliable gearboxes. However the generator’s need for rare-earth magnets, which are mainly produced in China, means they are an expensive alternative, with the market effectively subject to a monopoly.

GreenSpur Renewables look set to break this monopoly with a new type of generator that uses readily available ferrite magnets, which are 40 times cheaper than their rare earth equivalents.

While this new technology was born in the UK, its impact could be global.
