GKinetic 3 kW Tidal Turbine
The GKinetic 3 kW tidal turbine concept involves two cross-flow turbines placed on either side of a buoyant vessel with an airfoil shape (the foil's leading edge is perpendicular to seafloor and faces the incoming water flow). This unique shape of the vessel increases the speed of water into the turbines. The combination of the accelerated flow along with a patented blade pitch control system results in higher power outputs. There are no major civil works required, the device can simply be anchored in the water flow. Grant funding from the Sustainable Energy Authority of Ireland (SEAI) supported the deployment of the GKinetic turbine at the Limerick Docks for two sets of tests. The first series took place between October 2015 and January 2016, the second between August and October 2017. The 150 tow tests were completed with a total towing recording time of 843 minutes. This whole system can operate in water depths as low as 0.5 m, has a rated speed of 2.2 m/s, a cut-in speed of 0.6 m/s, a cut-out speed of 2.5 m/s, and weights 0.25 tons. In addition to the 3 kW unit, GKinetic also has a 12 kW market ready unit, and their strategic partner, DesignPro Renewables, is testing and commercializing 25 kW and 60 kW units.
