WEDUSEA will demonstrate a grid connected 1 MW OE35 floating wave energy converter (known as the OE Buoy) in Orkney, Scotland. This rigorous technical and environmental demonstration will happen over a two year period in Atlantic wave conditions with outcomes directly impacting policy, technical standards, public perception and investor confidence. The project will demonstrate that the technology is on a cost reduction trajectory in line with the EU SET Plan targets and will be a stepping stone to larger commercial array scale up and further industrialisation. The action will integrate sub components such as moorings and power take-offs - improving efficiency, reliability, scalability, sustainability and circularity of the technology.
