In Sweden, wheels have begun to launch a new type of wind turbine, and the country’s first wooden power tower has been built,media reported. The project is built with sustainable materials and is said to be comparable in performance to conventional wind turbines. The project hopes the wooden tower will be a pioneer in cheaper, greener renewable energy solutions in the Nordic countries, and plans to launch a commercial version in the coming years.
It is understood that the new wooden wind tower was built by Swedish engineering company Modvion to improve the obvious defects of traditional wind towers. These tall steel towers require a very thick base to support the upper structure, which not only makes them very expensive to produce, but also very high cost of transporting to the site, and the weight regulations on public roads are often a problem.
Instead, Modvion is developing a modular product that can be made from materials that are cheaper and more environmentally friendly than steel, which requires a lot of energy. The company’s wooden wind towers are designed to be more than 120 metres high and cost significantly less than steel towers, and the modular approach means that the transport of its components on public roads is not a problem. The team also said they were carbon neutral from the day of construction.
The 30-meter-high proof-of-concept tower was built by timber construction company Moelven’s plant in Torreboda. The wooden part of the turbine was then transported to Bjorko, an island off Gothenburg, about 200 km from Gothenburg, and the final part was installed at the end of April.
“This is a major breakthrough that paves the way for the next generation of wind turbines,” said Otto Lundman, CEO of Modvion AB. At the same weight, composite wood is stronger than steel, and wind turbines can be built in modules to be taller. By using wood construction, we have also reduced CO2 emissions from the manufacturing process and replaced them with the storage of CO2 in the design. “
If the Modvion project goes well, the company plans to launch a commercial version in 2022, including a 110-meter-high tower for Varberg Energi and 10 towers over 150 metres high for the renewable energy company Rabbalshede Kraf.
Ola Carlson, director of the Swedish Wind Power Technology Centre and assistant professor of renewable energy power generation, said: “Wind energy is expected to be the EU’s largest source of electricity as early as 2027. With wooden wind towers, we can get more climate-smart renewable electricity to deal with the climate crisis. “
