Speira and Bayards propose aluminium as an alternative material for the construction of the nacelles of modern wind turbines, instead of conventional materials such as glass fiber-reinforced plastic (GRP) or steel.

“We see Aluminium as a key material for the sustainable further development of the wind power industry.” explains Reinhard Pritzlaff, Technical Advisor at Speira.

“With Aluminium, we create almost closed material circularity that improves the environmental balance of wind turbines. ,” Pritzlaff continues.

Together with Bayards, Speira has developed a modular concept for nacelle cladding. Initial calculations show promising results:

• 18 percent less weight compared to GRP constructions

• 67 percent less CO₂ emissions during production

• 100 percent recyclability after each life cycle

Pritzlaff emphasizes: “Now is the time to actively drive material change in wind power. We want to add our materials expertise to the industry’s technical learning curve. With Aluminium, we are opening up a new dimension of sustainability.”
