Swedish offshore wind pioneer Hexicon is buying the long-dormant Wave Hub energy test site in the Celtic Sea off southwest England to trial its next-generation twin-headed floating design in a full 30-40MW array.

The acquisition from the local authority, the value of which was not disclosed, will see the company’s subsidiary TwinHub take over the site, a power ‘socket’ built off Cornwall in 2014 to trial wave power devices but never used.

“Hexicon sees the acquisition of Wave Hub and the deployment of our twin turbine technology in the Celtic Sea as an essential stepping-stone to fulfilling our long term ambition of developing utility scale floating wind projects capable of delivery long term consistent and secure renewable energy at the lowest possible levelised cost of energy,” said Hexicon CEO Marcus Thor.
