UK-based GreenSpur Renewables has received the Rushlight Wind Power Award for its direct drive permanent magnet (DD-PMG) generator.
The new generator uses inexpensive ferrite instead of expensive rare earth magnet neodymium iron boron (NdFeB), which is used in existing generator designs. Ferrite is abundant, accessible, and cheap to source.
GreenSpur Renewables developed a 2KW prototype of its DD-PMG generator using a grant from a £2.5m supply chain innovation for offshore renewable energy (SCORE) fund. A second grant of £50,000 was used to scale the generator up to 75KW.
The company's co-director Andrew Hine said: “For GreenSpur to be recognised at this stage of its development as a key innovator within the wind energy sector is hugely significant, especially as we are about to embark on scaling our technology to multi-megawatt levels.
“We will be testing a 75KW unit at the Offshore Renewable Energy Catapult’s test centre in Blyth. We see this as the start of a long and productive relationship with the Catapult and plan to test much larger units at the centre over the next 18 months.”
The company aims to begin testing of the low-cost DD-PMG generator at multi-megawatt levels within two to three years, as well as to work in collaboration with an original equipment manufacturer (OEM) to develop a generator suitable for market adoption.
The Rushlight Awards are given to support and promote the latest and advanced clean technologies, innovations, initiatives, and deployment projects across the UK, Ireland, and internationally.
