November 7 (Renewables Now) - GreenSpur Renewables Ltd, a UK-based company that has developed an innovative generator for wind turbines, has appointed the former finance head of Siemens Gamesa as its chairman.
Andrew Hall, who up until late last year served as chief financial officer of wind turbine manufacturer Siemens Gamesa Renewable Energy SA (BME:SGRE), has now joined GreenSpur and hopes to help the company bring its technology to market in 2019.
GreenSpur has developed what it says is the world's first ferrite-based direct drive permanent magnet generator for wind turbines that is capable of reliable multi-MW generation. It uses cheap and abundant ferrite magnets to replace scarce and expensive rare earth magnets.
The company plans to unveil the design for a 10-MW-plus generator for offshore wind turbines early next year and is working with Warwick Manufacturing Group (WMG), part of the University of Warwick, on the concept. Meanwhile, GreenSpur is scheduled to test a 250-kW stage of a 1-MW generator at the ORE Catapult in early 2019.
Commenting on GreenSpur’s generator, Hall stated that it is the first he has seen to credibly use low-cost ferrite magnets at multi-MW levels.
Apart from Hall, GreenSpur's board also includes the inventor of the above-mentioned technology -- Hugh-Peter Kelly, as well as Andrew Hine, Alex Freeman, Chris Heminway and Alison Cavey.
