The ancient craft of woodworking is being propelled into the future, playing a pivotal role in the global shift towards renewable energy. At the heart of this transformation is Modvion, a Swedish wood-technology company that is challenging conventional materials like steel and concrete with its groundbreaking modular wind turbine towers made from laminated veneer lumber (LVL). This innovative approach was recently showcased on the international stage at the IQPC Wind Week 2025 in Bremen, Germany, where it captivated an audience of industry leaders and sustainability advocates.
The event, which ran from August 26–28, 2025, brought together the sharpest minds in wind power. Wind Week 2025 was more than just a conference; it was a collaborative forum with four specialised tracks dedicated to different aspects of turbine technology. Modvion took the spotlight in the “Wind Turbine Towers” track, a segment focused on the next generation of solutions for building taller, more efficient wind energy infrastructure.
The presentation by Leo Anderson, Modvion’s Technical Sales Manager, highlighted the unique properties of wood that make it a superior choice for wind turbine towers. While steel and concrete have long dominated the industry, their heavy carbon footprint and logistical challenges for increasingly tall structures have created a need for a new solution. The push for taller turbines is driven by a simple fact: wind speeds are stronger and more consistent at higher altitudes. Taller towers can therefore generate significantly more power, making each turbine more productive and cost-effective. However, the sheer size of these towers presents a major logistical hurdle. Transporting a conventional 100-meter-plus steel tower on public roads is often impossible due to width and length restrictions, requiring complex and costly logistics.
Modvion’s patented modular design addresses this challenge directly. The towers are not built as a single, massive cylinder. Instead, they are constructed from smaller, curved LVL modules that can be easily transported on standard trucks. This modularity simplifies logistics, allowing for efficient delivery to almost any location, even those with winding roads or bridges that would be impassable for traditional steel components. On-site, these modules are assembled and stacked, creating a tower that is not only logistically feasible but also structurally robust.
Beyond the logistical advantages, the choice of wood offers profound environmental benefits. Steel and concrete production are responsible for a significant percentage of global CO2 emissions. By replacing these materials with laminated wood from sustainably managed forests, Modvion’s towers become a carbon-negative component. The wood itself stores the carbon dioxide absorbed by the trees during their growth, effectively sequestering more CO2 than is emitted during the tower’s production, transportation, and installation. This is a game-changer for the renewable energy sector, allowing for truly sustainable energy generation.
Furthermore, the strength-to-weight ratio of the LVL used by Modvion is superior to that of the steel typically used in turbine towers. This allows for the construction of lighter yet incredibly strong towers, which reduces the need for expensive reinforcements and further contributes to cost-effectiveness. In a panel discussion at Wind Week 2025, Anderson joined other material innovation experts to discuss how this shift is not just an option but a necessity for the future of the industry. The panel underscored that as turbines continue to grow in size and capacity, traditional materials will become economically and environmentally unviable. The woodworking industry, with its long history of innovation and its renewable resource base, is perfectly positioned to provide the solution.
The presentation resonated deeply with the audience, which included manufacturers, engineers, and policymakers all seeking pathways to a greener future. The reception underscored a growing recognition within the wind power community that material choice is a critical factor in achieving true sustainability and maximizing efficiency. The shift to wood represents a symbiotic relationship between two seemingly disparate industries: the traditional craft of woodworking and the high-tech world of renewable energy.
As the global demand for clean energy intensifies, companies like Modvion are demonstrating that the solution lies not just in a new type of power generation but in a new way of thinking about the materials we use. The future of tall wind turbines may very well be rooted in the forests of Europe, built with the ingenuity of woodworkers, and powered by the wind. For the woodworking industry, this is more than a new market; it is a powerful new purpose in the global effort to combat climate change.
