Exploitation of the offshore wind resource is a very innovative concept. Only 6 research groups in the world are working on the subject.
he development of wind, autonomous ship and energy storage systems such as electricity to gas or liquid are the key elements that make this concept possible today. However, much research is still needed to determine the best performing technical solutions.
Scientific advances and innovation
- Development of a Velocity and Power Prediction Program (VPPP) for drifting wind turbines.
- Optimization of anti-drift plane and propeller characteristics
- Evaluation of load factors
Expected technical and economic impact
Since 2016, the LHEEA research departement of Centrale Nantes – CNRS has been investigating the feasibility of far-offshore wind energy conversion. Indeed, the yet-unexploited far-offshore wind energy resource represents a tremendous potential of renewable energy.
To harvest this potential, a concept is the sailing wind turbine, which is neither grid-connected nor moored. This concept is promising because it removes the need for grid-connection, moorings and related marine operations, which corresponds to approximately half of the capital expenditures for floating offshore wind turbines. Morevoer, sailing wind turbines are mobile, thus their energy production can be optimized using weather-routing.
The EOLNAV project aims at investigating the potential of this concept using numerical modelling.
