UK pushes floating wind farms in drive to meet climate targets

In the waters 15km southeast of Aberdeen, renewable energy companies are preparing to celebrate yet another landmark on the drive to end their dependence on fossil fuels in the United Kingdom.

Five wind turbines taller than Gherkinville in London, anchored on a 3,000-ton buoyant platform, towed from Rotterdam to the North Sea, one of the world’s largest “floating” offshore wind farms, the Kincardin Array. Form a part. Wind farm.

Wind farm developers have made a move Since the 2000s It has floating technology to overcome the limitations of traditional offshore turbines. They are attached to structures fixed to the seabed and are difficult to install beyond a depth of 60m, making them unsuitable for areas far from coasts with high wind speeds.

Floating projects, anchored to the seabed by mooring lines, are rapidly shifting from the periphery to the mainstream as countries turn to technologies that help them achieve difficult climate goals.

Britain was the first country to set up Floating offshore wind farm Off the coast of Peterhead, Scotland in 2017. However, the size of existing floating projects is not very large. The Kincardin Array has a power generation capacity of 50 MW, while the world’s largest conventional offshore wind farm has a power generation capacity of 3.6 GW.

Larger wind developers are now strengthening their gear with plans to build larger and more schemes.

Orsted in Denmark, RWE in Germany, Equinor in Norway, Scottish Power in the UK and Royal Dutch Shell are just a few of the companies on the long list of bidders competing to build a floating scheme. Auction Ownership of the seafloor rights to approximately 10 GW of offshore wind projects in Scottish waters. The bidding round will end in mid-July and the winners will be announced in early 2022.

UK is investigating individually Auction Only for floating winds on the approach to the Celtic Sea, the Atlantic region west of the Bristol Channel, the English Channel and the South of the Republic of Ireland.

Developers expect the cost of floating projects to drop rapidly as more projects are deployed. The cost of floating offshore wind power in 2018 is estimated to be over € 200 per megawatt hour, almost double the cost of nuclear power in the UK.

Offshore Renewable Energy Catapult, a UK technology and research center, hopes developers will be able to build “unsubsidized” floating projects as early as 2029 at prices below the wholesale electricity costs expected at auctions. I am. UK Government Auction in 2019.

Britain’s Prime Minister Boris Johnson, who will host the UN COP26 Climate Summit later this year, has set a 1 GW fluctuation target from a total of 40 GW offshore wind targets by 2030. He “emphasized the importance of accessing the windiest parts of our oceans” is part of the UK’s goal of reducing carbon emissions to net zero by 2050.

Other countries, such as France, Norway, Spain, the United States, and Japan, are also pursuing this technology, with experts advocating traditional “fixed bottoms” due to countries with restricted access to shallow waters and the geology of the seafloor. It is said that it will be particularly appealing to countries where it cannot be installed. “Turbine.

WindEurope, an industry group, predicts that by 2050, one-third of all offshore wind turbines installed in Europe could be floating.

Countries pursuing floating offshore wind power are “not only an opportunity to reach their zero net goal, but also interested in it. It can also be a driving force for economic growth,” said offshore renewable. Ralphtor, Program Manager for Energy Catapults, said.

Just like the UK supply chain has Lose For foreign companies in the construction of traditional offshore wind farms, there are concerns that the UK may be more than anywhere else in the world, but floating technology mistakes may be repeated. Manufacturing operations for the Kincardin project took place in Spain and Portugal, with turbines and foundations assembled in Rotterdam.

Competition with other markets was already fierce, as everything sought to gain a “starter advantage”.this is [just] A handful of projects. “

Offshore renewable energy catapults and developers are calling on the government to promise a second goal for floating offshore wind power in 2040. We believe this gives confidence to the industry in investing in the necessary facilities in the UK.

“Because it’s floating [wind] It will be much better to understand what the long-term pipeline is, as it will be economical in the 2030s, “said Tom Glover, RWE’s UK country chair. He added that at the Scottish Undersea Rights Auction, developers need to “provide commitment and ambition for Scottish content,” which should benefit the local supply chain.

Wind developers recognize that UK suppliers need time to get ready. Christoph Harwood, Director of Policy and Strategy for Simply Blue Energy, 96MW floating scheme Off Pembroke, Wales, he said a project larger than the initial floating project, but not yet fully commercial, is important in the process.

“If the UK supply chain benefits from floating offshore wind, we will not rush into the 1GW project and will take some foothold towards them,” he said.

Tim Cornelius, Chief Executive Officer of the Global Energy Group, Naig harbor At Cromarty Firth in northeastern Scotland, he said the size of floating wind turbines provided an opportunity for UK suppliers.

Floating offshore turbines are much larger than traditional offshore turbines and should be built near the installation site. This will prevent you from using the cheapest manufacturers in China and the Middle East.

Floating offshore turbines require an “amazing amount” of deep shore wall space in the harbor, Cornelius explained. His company is considering building an artificial island for the wharf in Cromarty Firth, Scotland. This “requires a material investment, but as long as the developers are ready to commit, it’s perfectly justified,” he says.

But he warned: [UK] The supply chain is [floating offshore wind] industry”.
