Twin Hub Floating Wind Demo Gets Marine Licence

The Twin Hub floating demonstrator project in the Celtic Sea has now been awarded a marine licence for a renewable energy test site in Cornwall, South West England.


The marine licence is the latest consent for the project which was awarded a Section 36 consent in 2020.

Hexicon AB completed the acquisition of the consented site in July 2021 and will deploy its twin-turbine floating foundation for a 30-40 MW floating offshore wind demonstration project.

Hexicon is working with Bechtel, an engineering, construction, and project management specialist, to deliver the scheme.

The project is set to be the first floating offshore wind project in the Celtic Sea, a key stepping stone to the UK Government achieving its targetted 1GW of floating wind by 2030, Hexicon said.

The Celtic Sea is an important area for floating offshore wind development, with plans for up to 4 GW of new floating wind capacity to be unlocked in the Celtic Sea by 2035, as announced by The Crown Estate in November 2021.

”We hope that the TwinHub project will set a precedence for floating wind in the Celtic Sea,” Hexicon’s CEO Marcus Thor said.

”Being first up offers an opportunity for both us and the local supply chain to develop together, and build long term relationships to support Hexicon’s long term ambition of developing large scale floating wind projects in the UK. These projects will be capable of delivering consistent and secure renewable energy at the lowest possible cost. We look forward to developing these relationships in the coming years and supporting the plans for the Celtic Sea.”

The project plans to utilise the existing infrastructure already installed on the site, including an offshore export cable, onshore substation, and the existing grid connection agreements.
