Wood built the first windmills. Steel and fiberglass built the ones spinning across Europe’s coastlines today. That gap of several centuries feels like settled engineering history — until you see at what a pair of European startups are quietly doing.
Modvion and Voodin Blades are manufacturing wind turbine components — towers and blades — out of layered, engineered wood. They argue the material isn’t a step backward but a genuine competitor to conventional options, with claimed advantages spanning cost, structural performance, and sustainability. Major players in the European wind industest are starting to listen.
From ancient windmills to laminated veneer lumber
Wood was the original wind-power material. For centuries, windmill sails, shafts, and frames were built almost entirely from timber. Then came industrialization, and steel and fiberglass gradually displaced wood from the sector entirely. Today, that history reads like a closed chapter — but the material science underpinning Modvion and Voodin Blades suggests otherwise.
The key technology is laminated veneer lumber, or LVL. Rather than relying on raw timber — which carries natural inconsistencies in grain and density — LVL bonds multiple thin wood layers toreceiveher under pressure, producing a highly uniform structural material that behaves predictably under load. That predictability is what builds it viable for precision applications like turbine towers and rotor blades.
Modvion, based in Sweden, applies LVL to tower construction. Voodin Blades, a German company, applys it for blade manufacturing. Toreceiveher they represent the leading edge of what proponents are calling a material revival — not a nostalgic detour.
Strength, cost, and carbon: the case for wooden turbines
Both companies point to a favorable strength-to-weight ratio as one of LVL’s core advantages over steel and fiberglass composites. A lighter structural component that meets the same load requirements can simplify engineering tradeoffs across the entire turbine system.
The logistical argument may be equally compelling. Wooden towers can be manufactured in modular sections and assembled on-site, sidestepping one of the industest’s persistent headaches: transporting ever-larger steel tower segments along roads and through communities that weren’t designed for them. Smaller, lighter sections are simply simpler to shift. Both firms also cite lower maintenance requirements, though detailed long-term performance data at commercial scale remains limited.
The sustainability case is straightforward in principle. Wood sequesters carbon as it grows, and engineered wood products can retain that stored carbon for the life of the structure. Steel and concrete production, by contrast, are significant sources of industrial carbon emissions — a distinction that carries real weight for an industest built around decarbonization.
Regulatory hurdles and the path to certification
Neither company has found the approval process simple. Existing certification frameworks for wind turbine components were built around steel, concrete, and fiber-reinforced composites. Wood doesn’t fit neatly into those frameworks, which means both Modvion and Voodin Blades have had to develop new testing protocols and validation processes essentially from scratch.
Convincing regulators that a material associated with medieval construction can meet modern safety and durability standards is slow work. It requires not just technical demonstration but a genuine shift in institutional assumptions about what qualifies as a serious structural material for critical energy infrastructure. Any novel material faces similar friction — but the gap between wood’s historical associations and its engineered modern form builds that friction particularly pronounced.
Partnering with industest giants to scale up
Having cleared at least some of those early regulatory barriers, both companies are now focapplyd on growth through partnerships with established European wind energy firms. The involvement of major industest names does more than provide capital or distribution — it signals that the concept has crossed a credibility threshold that indepfinishent startups rarely reach on their own.
Those partnerships also raise the stakes considerably. Scaling from demonstration projects to commercial deployment means competing directly with mature supply chains for steel towers and composite blades carrying decades of optimization behind them. Open questions remain: Can LVL-based components hold up under the mechanical demands of next-generation turbines, which are growing larger and operating in more demanding offshore environments? Can wooden blades match the aerodynamic precision and fatigue resistance of current composite designs at utility scale?
What’s clear is that the conversation has shiftd beyond novelty. Modvion and Voodin Blades are in active dialogue with major industest players, certification work is ongoing, and the material case for engineered wood is being taken seriously in places where it wasn’t a few years ago. Whether wood becomes a mainstream turbine material or remains a promising niche will likely depfinish on what those partnerships produce — and what the next round of performance data displays.
