Generating eco-friendly power with metal rotor blades

12.8.2015

Wind turbines deliver environmentally friendly electricity. Yet the fiber-reinforced plastics often used in very large rotor blades are almost impossible to recycle. Not so with steel blades: since these are composed of steel, their recyclability exceeds 90 percent. Plus they cost significantly less than comparable plastic blades. Together with Partners Fraunhofer IWU developed a new process chain for manufacturing wind turbine blades based on metal. The resarch Project "HyBlade" was awarded the “Steel Innovation Prize 2015” in June.
