Manganese and wind power
Manganese is an essential material for wind power generation. It is used as part of steel components, generally, in the tower, nacelle, and gearbox of the wind turbines. There are four main types of wind turbines: direct-drive electrically excited synchronous generator (DD-EESG), direct-drive permanent-magnet synchronous generator (DD-PMSG), gearbox permanent-magnet synchronous generator (GB-PMSG), and gearbox double-fed induction generator (GB-DFIG). The manganese usage estimates for these four types of wind turbines range from 780-800 t/GW.
