Revolutionary Technology

Our active pitch control solves the fundamental challenges of conventional vertical axis wind turbines.

Maximized Efficiency

Active pitch control optimizes blade angles in real-time, dramatically improving energy capture compared to conventional VAWTs.

Reduced Vibrations

No aerodynamic vibrations or fatigue loading. Blades align with wind in storms, enabling lighter construction.

Self-Starting

Overcomes the traditional VAWT challenge of poor self-starting capabilities through active pitch optimization.

Simpler Design

Straight, supported, modular blades suitable for aluminium construction. No complex 3D-curved composites needed.

Higher Density

Achieve 3 to 5 times higher energy extraction per square meter through superior wake recovery and closer turbine spacing.

Offshore Ready

Generator at sea level and modular design make it ideal for floating offshore wind farm applications.

How Active Pitching Works

Fast, self-sensing, self-learning electric blade pitching for complete flow control. Our system continuously adjusts each blade's angle during rotation to keep the angle of attack close to optimal. Instead of fighting the changing inflow, the turbine actively uses it.

  • Higher efficiency than conventional turbines
  • No aerodynamic vibrations or fatigue loading
  • Reliable self-starting at lower wind speeds
  • Align with wind in storms for lighter construction
  • Much more silent operation

Where conventional fixed-pitch VAWTs see their performance limited by the changing inflow angle around the rotation, our active pitching approach turns that variability into an advantage.

Fixed Pitch: Separated Flow

Flow separates from the blade, creating drag and turbulence.

Active Pitch: Attached Flow

Flow stays attached, maximizing lift and efficiency.

FliHy VAWT prototype in the University of Twente wind tunnel

Proven in the Wind Tunnel

Our active pitch concept has been validated on a fully modular VAWT prototype in the University of Twente wind tunnel, providing a robust research platform to characterize the flow field and wake behaviour.

We are now translating these research results into a 50 kW system designed for both decentralized and floating offshore applications.
