US Energy Department Wants to See Lighter Offshore Wind Turbines

▤ Summary

ABB subsequently confirmed to Greentech Media it will not pursue the research project it had planned under the DOE grant, but the other three remain active. WEG Electric Corporation plans to develop a lightweight generator designed both to use less rare earth materials than conventional geared turbines and to be integrated into its existing platform. The other two project teams — American Superconductor and GE — are developing superconducting generators expected to greatly reduce the need for rare earth materials. What is new is some of the cryogenic technologies that have evolved over the years for MRI we can now bring to electric machines to make them practical,” David Torrey, GE’s team leader, told Greentech Media in an interview. “The design cycle for offshore turbines is very long, due to the massive scale of the technology, significant supply chain investment, and high risk that dictates extensive validation periods,” said Barr.
