“Subhub’s primary role is to support all the requirements for tidal turbines. The design can be adapted so it can host any type of turbine”.
Subhub platform can be designed around any type of tidal turbine be it vertical axis or the more typical horizontal axis turbines.
Community Scale Tidal Turbines
The Subhub Community Demonstrator is design around a 4.0m diameter Tocardo T1 tidal turbine. These are auguably the most robust, reliable and well proven tidal turbines in the world having had over a decades worth of operation and development in Den Oever, Holland, shown below.
Nova Innovation are a leading tidal turbine developer based in Scotland and have been developing a very cost effective turbine in the world’s 1st instream tidal array.
Schottel Hydro have developed a very efficient, high power to weight ratio tidal turbine to compete on cost for mass produced solutions.
All these turbines are sub-100kW to produce power at community scale.
Industrial Scale Tidal Turbines
Tocardo tidal turbines are pretty unique in that they are one of the few tidal turbine developers that produce an industrial scale tidal turbine using their T2 SI turbines like those installed in Eastern Scheldt. This is one of the main dykes protecting Holland from flooding so the design is incredibly robustness and design for extremely high flow rates.
Utility Scale Tidal Turbines
Examples of utility scale tidal turbine developers that QED Naval have worked with are below:
