GKinetic Energy has received United States patent approval for a hybrid blade pitch control mechanism designed for vertical-axis hydrokinetic turbines operating in flowing water environments, International Water Power reported

The patented system, titled Blade Pitch Control Arrangement, enables active, passive and free-trailing blade operation within single rotations. This configuration allows maximum energy capture during optimal phases whilst reducing mechanical stress when blades align with flow patterns in rivers, canals and tidal estuaries.

The technology supports operation at reduced rotational speeds using increased blade counts, targeting improved performance in the variable flow conditions characteristic of riverine and tidal installations. GKinetic characterises the approach as enhancing both power output and equipment durability.

Vincent McCormack, chief executive, and Gary Brennan, chief technology officer, are listed as inventors on the patent granted to GKinetic Energy Limited. The County Limerick company developed the intellectual property with Enterprise Ireland support through its IP Plus Programme.

"Securing this patent is a significant milestone for GKinetic and a strong validation of the engineering approach behind our hydrokinetic technology," McCormack said. "Blade pitch control is fundamental to performance and survivability in hydrokinetic energy, and this invention underpins our ability to deliver efficient, robust and scalable turbines for commercial deployment."

Joe Doyle, intellectual property manager at Enterprise Ireland, noted the patent demonstrates innovation depth within Ireland's renewable sector. "Protecting core intellectual property such as this is critical for scaling internationally and attracting global partners," Doyle said.

GKinetic stated the patent strengthens its portfolio as the company advances from technology development toward commercial project delivery in Ireland and international markets.
