ExoTechnologies (Douglas, Isle of Man, U.K.) and renewable energy company (Stavanger, Norway) have announced the launch of a fully recyclable wind turbine. Enabled by ExoTechnologies’ natural fiber-reinforced thermoplastic Danu composite, the market-ready turbine is set to debut in 2025.
The represents the culmination of a year-long collaboration. Reimagined, it has been purpose-built for commercial and industrial rooftops, offering an energy solution for manufacturing facilities, warehouses and multistory buildings, complementing solar PV by generating energy under diverse weather conditions and at times when solar may fall short
According to Venture Dynamics’ website, “the vane shroud design accelerates wind capture, enabling a greater volume of air to pass through the turbine. This focused wind is directed straight toward and across the entire rotor disc with minimal energy losses, optimizing power capture at the rotor.” Its omnidirectional design also makes it capable of capturing wind from all directions, delivering up to 3,000-5,000 kilowatt-hours annually. Operating at a level of under 40 decibals, it boasts a projected levelized cost of energy (LCOE) of just €0.05/kilowatt-hour, reportedly setting a new standard in renewable energy efficiency and versatility.
The use of Danu is said to eliminate waste at the end of the wind turbine’s life cycle, reduce CO2 emissions during production and deliver high performance. The material technology reduces overall turbine weight by 40% and improves structural integrity by 30-65%, depending on the component. In the VX175, Danu also enhances wind responsiveness, with key components like the shroud and rotor blades achieving increased stiffness and resilience, ensuring long-term durability under high-stress conditions.
