innOring
Developed by REGGS & Innovici Innovation, innOring is a ducted wind turbine that accelerates, stabilizes and amplifies airflow delivering far more energy than a conventional open rotor of the same size with low noise and minimal environmental impact.
Designed for versatile installation, on rooftops, industrial sites or as a stand alone unit, InnOring brings renewable wind energy to places where conventional turbines cannot be implemented.
Only by combining these three elements can a compact wind turbine become economically attractive. The result is a system that can be offered at a realistic market price while delivering a return on investment that, under the current economic and policy conditions, can offer an attractive complement to solar installations. This advantage is further strengthened by the innOring’s ability to generate energy at night and throughout autumn, winter and spring, when solar production is low.
With an expected operational life of at least 20 years, the innOring continues generating value for many years after reaching its return on investment. This means significantly more years of low-cost energy production and an extended period of positive cash flow.
In addition, the current opportunities created by ERE certificates and other renewable energy incentives further strengthen the business case. Every year of delay is a year of lost energy production and missed financial benefits.
The best moment to start generating clean energy was yesterday. The second-best moment is today. With innOring, you can turn wind into long-term value, lower energy costs, and a more sustainable future.

European design & manufacturing
innOring is designed to deliver high energy output from a compact footprint and a rotor diameter of 1.99 metres. Its aerodynamic shroud accelerates and stabilizes the airflow around the rotor, increasing local mass flow and speed and improving performance in realistic wind conditions. Its dedicated shroud airfoil is designed to maintain strong performance when wind enters off-axis, which is important in real-world wind conditions. Annual yields of approximately 2,800 kWh at 5 m/s, 3,600 at 5.5 m/s, 4,700 kWh at 6 m/s and 7,000 kWh at 7 m/s are expected, with even higher potential at wind-rich locations like the Caribbean.
The aerodynamic concept has been developed through years of CFD modelling and iterative optimization of the shroud, rotor and blade geometry reaching a Cprotor of 0.79 in nominal wind conditions and even 0.81 when wind is approaching under angles up to 20 degrees of axis. An independent review by TNO (the Netherlands Organisation for Applied Scientific Research) concluded that the CFD setup is professionally executed, well converged and physically plausible. This gives a strong technical basis for further validation through full-scale field testing.
innOring is designed for locations where conventional small wind turbines are difficult or impossible to integrate. Its compact, low-noise and enclosed design makes it suitable for high rooftops, industrial sites, farms and business parks. It is primarily intended for professional and commercial applications rather than private residential homes.
innOring is engineered for durability, low maintenance and reliable operation. The system uses a direct-drive generator without a gearbox, a low rotor tip-speed ratio and a design philosophy based on low vibration, controlled mechanical loads and redundant safety functions. The construction is aimed at long-term use in demanding rooftop, industrial and standalone applications. High-end materials have been selected for a design life of at least 20 years: stainless steel, a lightweight frame, recyclable plastics selected for durability, carbon composites and an industrial-grade generator and electronics.
With a compact design, high annual energy yield and efficient European robotic production setup, innOring is designed for a short environmental payback period. Current lifecycle calculations estimate a carbon payback time of approximately 6 to 11 months, meaning the system can quickly offset the carbon impact of its production during operation. Every year of operation after that contributes to ongoing CO₂ reduction until the innOring reaches the end of its technical lifetime.
The rotor blades are developed together with Ex-Core, using advanced carbon composite manufacturing technologies that are also used in Formula 1 motorsport.
The blade design combines low weight and high stiffness, aerodynamic precision and production scalability, supporting high efficiency while keeping mechanical loads, vibration and noise within strict design boundaries. Together with Donkervoort/Ex-Core, we developed technology that combines carbon-composite manufacturing with a high-quality gel-coat exterior to improve UV stability.
innOring is being developed to combine high yield, a competitive market price reached by robotic manufacturing and a long lifespan. A direct-drive drivetrain, high quality materials and low-maintenance architecture reduce total cost of ownership. The commercial target is an end-user payback period of approximately 3-9 years depending on average wind speeds of 4.5–7 m/s. This excludes the additional value of ERE certificates applicable for The Netherlands, which can potentially generate €0.17 up to €0.26 per kWh in additional revenue.
The innOring rotor is designed to operate at relatively low rotational speed, with a tip-speed ratio of approximately 4.3 (conventional wind turbines typically operate at a tip-speed ratio between 7 and 8), which helps reduce aerodynamic noise. Combined with the aerodynamic shroud and optimized blade design, this helps limit noise and makes the turbine suitable for locations where conventional small wind turbines are difficult to integrate.
innOring is designed for minimum impact on people, the built environment and nature. The rotor is enclosed in an aerodynamic shroud, helping shield the rotating blades and supporting safer integration at height. The design also aims to exclude shadow flicker and is aimed at use on rooftops, industrial sites and standalone locations where a low visual and ecological footprint is important. According to Waardenburg Ecology’s expert judgement, the innOring’s low hub height and very small rotor surface, enclosed within a wind tube, make it virtually impossible for birds and bats to fly into the rotor.
innOring is developed by REGGS and Innovici Innovation and is designed and manufactured fully in Europe. The production chain is built around specialized European partners for the shroud, frame, generator, carbon blades, control electronics and system integration. This supports quality control, supply-chain transparency and scalable local production.
The innOring is designed for compact, cost-efficient transport across Europe and to markets worldwide. The complete system is dimensioned to fit inside standard elevators, allowing it to be transported efficiently to rooftops for on-site installation and integration. Its modular construction, straightforward system integration and clear user manual enable local installation by skilled technicians and capable DIY installers, reducing the need for specialized on-site support.
