Voodin Blade Technology has announced the installation of the world’s first wooden wind turbine blades in Germany, marking a significant step toward reducing the environmental impact of wind energy. Despite its reputation as “green,” renewable energy still relies on components that can harm the environment. By pioneering these wooden blades, Voodin Blade Technology aims to make wind power generation more eco-friendly.
The Era of Wooden Wind Turbine Blades Begins In a recent announcement, Voodin revealed that 19.3-meter wooden blades have been installed on an existing turbine in Germany, claiming them as the first of their kind in the world. Current reports suggest that 85-95% of a wind turbine’s components are recyclable, but the blades’ typical construction using specific resins makes recycling difficult. Tom Siekmann, CEO of Voodin Blade Technology, states that most blades end up in landfills or are incinerated at the end of their life cycle. However, the new wooden blades emit 78% less CO2 during construction and reduce production costs by 20%.
Siekmann warns that if current trends continue, by 2050, we could face 50 million tons of blade waste, equivalent to eight times the weight of the Great Pyramid of Giza. To combat this, Voodin is using laminated veneer lumber (LVL) to create high-strength, lightweight components with a minimal carbon footprint. This material offers a more sustainable alternative to industry-standard blades made of epoxy resin-bound fiberglass and carbon fiber, which are challenging and costly to recycle.
Collaboration for a Sustainable Future Voodin is partnering with pulp and paper giant Stora Enso to develop these wooden blades, with plans to construct 60- and 80-meter blades in the future. Stora Enso is also collaborating with Modvion, a company known for constructing the world’s tallest wooden wind turbine tower.
The development of wooden blades comes at a critical time. Traditional wind turbine blades have a lifespan of 20 to 25 years, and the first generation of turbines is approaching the end of their service life. This new approach with wooden blades offers a more sustainable and cost-effective solution to the growing issue of wind turbine waste.
