The solution to Rare Earth-free energy

GreenSpur is a UK company, which has successfully developed a new Rare Earth-free generator to address critical materials supply chain risk.

Our generator has been developed and has completed detailed testing at the Offshore Renewable Energy Catapult in Blyth, UK. We are now focused on commercialising it for use within the wind and tidal markets.
Our goal is to deliver the most environmentally friendly generator ever built. Our unique modular design means we can deliver solutions from 10kW to 20MW plus levels. We have a clear technology roadmap map to guide our commercialisation strategy.
The GreenSpur generator contains 11 inventions covered by 51 patent assets around the world, of which 33 are granted patents.

Reduced Critical Materials Risk

The GreenSpur generator is a game-changing, cost-efficient solution, which addresses the critical materials risk facing the renewable energy sector.
Our team has developed a highly innovative, axial flux, Rare Earth-free, permanent magnet generator (PMG). It incorporates multiple innovations, which make the use of ferrite magnets possible. It also uses patented aluminium coils to replace the copper windings used within existing generators and composite materials to aid lightweighting.

Pioneering Partners

Our PMG has been developed with the support of two collaborative partners:

1. The Offshore Renewable Energy Catapult (OREC)
2. Warwick Manufacturing Group (WMG)

We continue to work with both organisations to scale our technology.
To demonstrate the benefits of our Rare Earth-free PMG, we have developed a whole-system model approach. We are now able to compare our results against state-of-the-art wind turbines and industry benchmarks.
