UK company GreenSpur Renewables is developing an up to 10 MW generator using iron-based magnets that could offer an alternative to the rare earth elements (REEs) used in wind turbines. The company, which has been working with a number of partners including Siemens and Alstom, says its technology will be able to produce electricity at prices comparable to those for conventional power stations. In 2019, the company will assess the device's thermo-mechanical performance.
UK company GreenSpur Renewables is developing an up to 10 MW generator using iron-based magnets that could offer an alternative to the rare earth elements (REEs) used in wind turbines. The firm is working on a prototype using ferrite-based magnets combined with GreenSpur's axial-flux rotor design which computer modelling has suggested could be just as powerful as REE-based versions. In 2019, the company will assess the device's thermo-mechanical performance.
