A consortium comprising Chantiers de l’Atlantique, France Energies Marines, Fondation OPEN-C, GE Vernova, Nexans, RTE and SuperGrid Institute has launched the RHODÉ research and development project focused on floating high-voltage direct current (HVDC) grid connection technology for deepwater offshore wind farms.
According to the consortium, the project aims to prepare for the deployment of the first 320 kV and 525 kV floating HVDC connections in France from 2040 onwards, and will develop and test key technologies required for future high-power floating HVDC connections, including transformers, gas-insulated substations, offshore AC/DC converter stations and dynamic HVDC cables.
