Trio of floating wind power pilots tack forward in 'vital step' for Celtic Sea play

UK Crown Estate greenlights 100MW Whitecross and Llŷr and Llŷr 2 arrays for 'technical competence, delivery capability and technological innovation' ahead of environmental impact check

Three floating wind arrays vying for development in the Celtic Sea have cleared a hurdle a key check by the UK’s seabed landlord, the Crown Estate, for their “technical competence, delivery capability and technological innovation”.

The trio, the 100MW Whitecross, being planned by Offshore Wind Ltd – a partnership between Flotation Energy and Cobra – off the coast of south-west England, and the same-size Llŷr 1 and 2, under development by Floventis Energy – a joint venture between SBM Offshore and Cierco – off Wales, were called a “vital step” in the UK’s offshore wind ambitions.

“Innovative projects like these represent a vital step towards the UK’s ambitions to develop floating wind at a commercial scale,” said Huub den Rooijen, managing director of the Crown Estate’s Marine portfolio.

“Not only do they help support the commercialisation of the market while bringing down costs, they are key to testing new designs, materials and construction methods while creating new opportunities for the regional supply chain.

“This sort of new technology will have an important role to play as the UK transitions to net zero, helping unlock new energy capacity, while potentially helping to reduce the impact on the marine environment.”

The three projects, in the running to be among the first in an offshore calculated to be home to a potential of 50GW of capacity, have been proposed in response to the UK Crown Estate’s plans in March to offer seabed leasing for commercial-scale floating wind in the region via individual projects of around 300MW in response to what it called “strong interest” from a “capable and motivated pool of potential market participants”.

The projects, which will each test “new foundation and mooring technologies, new designs, materials and construction approaches”, will now face a so-called habitats regulations assessment to assess possible environmental impacts. Passing these would qualify the three to be granted seabed agreements for lease.

Developer Blue Gem – made up of TotalEnergies and Simply Blue – last year won the rights to develop the 96MW Erebus demonstration project, with an eye to bringing the flagship array into operation off Wales in 2025-26.

The UK government’s target is to deliver 1GW of floating wind capacity in its waters by 2030.

“Together with Erebus project and TwinHub’s project at the WaveHub site [off south-west England, this trio] could quadruple the capacity of the floating wind pipeline in the Celtic Sea alone, to over 400MW,” said the Crown Estate, which noted that some 130MW of floating wind is currently installed globally.

Industry body RenewableUK’s director of future electricity systems Barnaby Wharton said: “Projects like these... can stimulate further investment in the UK supply chain for floating wind, manufacturing state-of-the-art technology not only for projects here but also for the global market which is expected to be worth at least £230m ($318m) a year by 2031 to UK exporters.

“And the more floating wind we install in British waters, the cheaper it will become; this innovative technology can repeat the success of fixed-foundation offshore wind by becoming subsidy-free within a decade.”

Floating wind markets are on the verge of explosive growth globally with analysts expecting a near-1,000-fold expansion of the current fleet as international supply chains take shape to support development of commercial-scale projects around the world, including in key markets in Europe’s northern seas , as well off the US west coast and in Asia Pacific region, where DNV believes half of a forecast 260GW of worldwide floating wind forecast will be turning by 2050.
