The world’s largest turbine maker, Vestas Wind Systems A/S, is partnering with ArcelorMittal to use recycled or old steel to make turbine blades with the aim of cutting carbon footprint.
A new Baltic Sea wind farm will power more than 1.5 million Polish homes using these greener steel turbines.
“It’s a huge step forward,” Lisa Ekstrand, Vestas’s head of sustainability, said in an interview.
“For a long time, we’ve been zooming in on steel particularly because we have known since the beginning that it’s a key lever for the world to meet its climate commitments and to reduce emissions.”
There’s a growing focus on improving the beginning and end stages of a turbine’s life.
One startup, supported by Vestas, is using timber to create towers. Additionally, some companies are repurposing old blades, mostly made of fiberglass, to build pedestrian bridges or park benches.
Although the electricity produced by traditional turbines is environmentally friendly, the process of building them is not as eco-friendly.
This is because they rely on materials like steel and iron, which have high energy requirements in their production.
With increased focus on achieving climate goals, there is a growing emphasis on making the renewable energy sector more sustainable.
