The renewable energy company RWE Renewables and the Swedish wind turbine developer Modvion are collaborating to manufacture the first 6 MW wooden turbines for onshore wind farms. This agreement is part of RWE’s ambitious plan to increase clean electricity production while reducing carbon emissions, according to a press release from the company this week.
“We see that multi-layer modular wooden turbines have significant market potential and can contribute to reducing the cost of new renewable electricity production by replacing steel and concrete with environmentally friendly and climate-adaptive wood,” said Lars Borisson, an expert at RWE Renewables.
According to Maria-Lina Hedlund, Chief Financial Officer and Acting CEO at Modvion, their wooden turbine technology can significantly help the wind power industry reduce emissions while enabling taller turbines to capture stronger winds.
“Wood is a renewable material that allows for drastic reductions in emissions. According to life cycle analysis from the Swedish research institute RISE, using wooden turbines can reduce emissions by 90% compared to conventional steel turbines of the same height and load. Wood also stores carbon, so the climate impact of wooden turbines is lower,” Hedlund explained. “By using wood materials, the turbines become carbon-negative as they store more carbon than is emitted during production.”
Modvion’s patented multi-layer wooden turbines are also sturdier than their steel counterparts at corresponding weights. Thanks to their modular design, they are easier to transport during construction.
“The goal is to further enhance the sustainability of wind energy. Wooden turbines can play a crucial role in helping the wind energy industry achieve carbon neutrality. As one of the world’s leading renewable energy companies, this partnership aligns perfectly with RWE’s goal of becoming carbon-neutral by 2040,” Borisson emphasized.
The first commercial wooden turbine from Modvion and RWE is expected to be installed in 2023. With a capacity of 6 MW, it will be one of the largest onshore wind turbines.
