Rare-earth magnets in turbines
NdFeB permanent magnets enable compact direct-drive and hybrid generators. Bayan Obo and Ganzhou dominate mining and separation; U.S. Mountain Pass ore often travels to China for processing.
Blade and nacelle logistics
80m+ blades face road curvature and bridge limits from Gulf ports to ERCOT sites. Offshore projects require marshalling at Esbjerg, Great Yarmouth, or Rotterdam plus scarce jack-up vessels.
Offshore marshalling
Dogger Bank-scale offshore wind depends on North Sea ports and heavy-lift vessels. SGRE and Vestas assembly hubs feed marshalling before turbine sets sail to project sites.
