Key sessions at All-Energy 2024 in Glasgow addressed the challenges and opportunities for UK North Sea offshore wind developments. The failure of Allocation Round 5 (AR5) last year still preyed on some minds, despite the promise of a more inviting contract for difference (CfD) deal in AR6. There were concerns about the pace of supply chain development. However, there was also recognition of the advantages of Scotland in terms of offshore engineering experience and an established skill and innovation base. New Energy World Features Editor Brian Davis reports.

Under its April 2024 Offshore Wind Industrial Growth Plan, an alliance of the Offshore Wind Industry Council, The Crown Estate and Crown Estate Scotland, and RenewableUK proposed that UK manufacturing capacity could be tripled in the next 10 years.

 

At the time of launch, Claire Mack, Chief Executive of Scottish Renewables said: ‘The UK stands on the cusp of a golden opportunity to build a world-class offshore wind supply chain.’ What’s more, she sees the Industrial Growth Plan charting a clear course for the collaboration needed between governments and industry in the years ahead.

 

Tim Pick, former Offshore Wind Champion and now Chair of the Offshore Wind Growth Partnership, put the cat amongst the pigeons when he admitted to the All-Energy 2024 delegates that he oscillates between ‘euphoria one minute and depression the next!’ He emphasised that the UK is not alone in this endeavour, and claimed: ‘Many of our overseas friends are looking at what we do and seeking to learn from how we endeavour to build out offshore wind.’

 

Pointedly, Pick saw Auction Round 5 as ‘a game of chicken where both sides lost – the government and energy companies!’ However: ‘It didn’t have to be that way, and wasn’t a great start when we see the valuation of the North Sea auctions.’

 

Looking forward, Pick said he is ‘still hopeful we can look back on a time when the UK has doubled down on a new generation of [offshore wind] technology for its future energy system'. Furthermore, he said: ‘There is a clear case for wind power-based approvals in the North Sea and Celtic Sea sending a ripple of confidence through the ports and country.’

 

He also recognised there were many reasons for bottlenecks in the supply chain: global politics, the impact of the US Inflation Reduction Act (IRA) and the critical absence of sustainable partners in the supply chain.

 

Nevertheless, ‘the funding seems to be coming together’, he said. As to the £500mn fund committed over five years by the Scottish government and the Crown Estate to catalyse private investment in offshore wind infrastructure and manufacturing facilities, ‘we’re hoping [it] will accelerate more developer-led initiatives’, Pick said.

Major commercial-scale floating initiative

In April, offshore planning consent was granted by the Scottish government to Europe’s first commercial-scale offshore wind farm to power oil and gas rigs in the North Sea. The Green Volt wind farm, to be located 75 km off the coast of Aberdeenshire, is a co-owned 50:50 development split between Flotation Energy and Vørgrønn (a joint venture between Plenitude (Eni) and HitecVision), which will consist of 35 floating wind turbines providing up to 560 MW of electricity. 

 

This is the first project consented in the Crown Estate Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round, and is seen as a significant milestone in Scotland’s bid to be at the forefront of floating wind technology.   

 

A pipeline of opportunities  
At All-Energy, Christopher Pearson, Project Director at Flotation Energy, maintained that it was important for floating energy initiatives to move forward consistently. He said that most people are impressed by the scale of offshore wind initiatives in the North Sea. ‘These are large-scale projects which really show the energy transition in action.’

 

He mentioned that the several billions of capital expenditure (capex) earmarked on existing offshore wind projects and infrastructure was ‘a pipeline of opportunities’. However, ‘the issue is how well knowledge from fixed offshore installations can be transferred to floating offshore projects… and assure that a suitable supply chain will be coming’.

 

Jonathan Cole, Chief Executive Officer of Corio Generation, added that one of the big bottlenecks in offshore wind is the build-out of the transmission system. ‘Because there is a lack of strategic planning of the network and a lack of willingness to meet anticipated issues with a system which is fit-for-purpose in the original design.’

 

But it’s all part of a bigger picture in the drive towards net zero.

 

Susan Lind, Managing Director of BlueFloat Energy and Renantis Partnership, pointed out that expanding offshore wind is a global ambition. According to COP28 in Dubai, offshore wind capacity needs to triple globally within 10 years to tackle climate change. ‘With a predicted 380 GW capacity across 32 markets, this is an incredible economic opportunity,’ she said. ‘If we can scale up to meet this demand, Scotland could potentially lead the world, creating 100,000 jobs by 2030, which will stimulate economic growth, increase our energy security and create vast new wealth.’ However, she admitted: ‘We will still face inflationary pressures, supply chain bottlenecks, rising opex and increased global competition.’

 

A portfolio of offshore wind projects

BlueFloat Energy’s portfolio in both fixed and floating wind projects comprises 34.1 GW of planned capacity in 10 countries across the globe. In early 2022, BlueFloat Energy and its partners secured three seabed leases (with a total capacity of 3 GW) in the Scotwind leasing round. In 2023, BlueFloat Energy and Renantis Partnership signed seabed exclusivity rights to develop two 99 MW projects under the innovation arm of Crown Estate Scotland’s INTOG auction.

 

BlueFloat is developing two floating wind projects of 1 GW capacity in Wales and south-west England, and is also looking at Celtic Sea developments, as well as pioneering offshore wind projects with Sener Renewable Investments and Plenitude in Spain. In addition, it is looking at offshore wind projects with Renantis in Italy, as well as early moves in Australia, New Zealand, Portugal and the Philippines.   

 

Gillian Morrison, Supply Chain Development Manager, Crown Estate Scotland, also claimed that floating wind has the potential to achieve rapid growth, with sustainable business development and community and regional benefits for generations to come. Currently there is nearly 40 GW of wind farms operating in UK North Sea waters and 20 GW of that is floating wind energy under development.

 

Morrison insisted: ‘We cannot be complacent. This is a global market with ever-growing plans. Supporting the development of offshore wind is one of the most important roles that UK government is charged with.’

Scotland’s dramatic offshore growth plans

Offshore wind is already Scotland’s second largest source of renewable energy – after onshore wind, and this capacity is set to increase dramatically over the coming decade. There are currently three commercial fixed bottom wind farms (Robin Rigg – 174 MW, Beatrice – 588 MW and Moray Firth – 952.5 MW) and four test and demonstration offshore wind farms in operation, two of which are floating (Hywind Scotland – 30 MW and Kincardine – 49.5 MW). In addition, Seagreen – 1,075 MW, the world’s largest and deepest fixed-bottom project, is fully validated and soon to be fully commissioned. Two further wind farms are under construction, Neart na Gaoithe – 448 MW and Moray West – 882 MW capacity. Beyond those two, some 20 projects with a combined intended installed capacity of 271.6 GW hold option agreements awarded under the Scotwind leasing process.

 

Scotland’s Innovation and Targeted Oil and Gas (INTOG) is a new leasing opportunity for offshore wind farms to help maximise value from commercial-scale development and to reduce carbon emissions associated with North Sea oil and gas production.

 

The Supply Chain Development Statement (SCDC) process introduced by Scotwind and INTOG requires Scotwind applicants to produce information about the supply chain expenditure expected from their projects, in terms of ‘local content’ for develoment, manufacturing, fabrication, installation and operations.

 

In order to be granted permission to participate in Scotwind, applicants had to commit to invest £1.5bn in local supply chain content, according to Crown Estate Scotland.   

 

The dangers of delay  
Maf Smith, Chief Executive of Lumen Energy, stressed the dangers of delay in development of floating offshore wind supply chains compared with foreign competition in this growing market.

 

He recognised there were learnings from fixed offshore wind installations, in terms of the benefits of having a standardised, industrial process for critical components when scaling up to high volumes, as well as lessons from oil and gas in terms of deep foundations and moorings. ‘But the danger in the floating wind market is developing late in support of a pipeline of projects in a massive supply chain, compared to the APAC [Asia-Pacific] countries and America.’

 

Offshore wind in action globally  
Chris Harvey, Category Director of Floating Wind at Corio Generation, said the company has 30 GW of offshore wind projects currently underway. The most advanced floating wind project is a 1.5 GW wind farm in South Korea with partner TotalEnergies, as well as having interests in projects across the UK, Norway, France and the Middle East, and longer-term interests in Spain and Portugal.

 

‘A number of individual demonstrators are planned and should be starting to order components,’ he said. ‘Beyond 2030, we see it [supply chain ordering] ramping up rapidly. By 2035, we expect that China will lead the way with 3.5 GW of floating wind, followed by South Korea and the Netherlands with 1.8 GW each, and France, the UK and US with 1.3 GW each.’

 

Moreover, he continued: ‘Floating offshore wind is a good market for the UK with a strong pipeline of potential projects. But we are not aligned to floating wind… it’s a bit of a luxury in some cases. And there’s a challenge in how to get the right resources to support offshore wind. The supply chain right now is struggling financially. They are focused on core projects which are typically more fixed-bottom as opposed to floating wind… The size and scale of the potential is large, but floating wind is in competition with other renewable energy markets.’

 

In conclusion  
On the critical issue of cost reduction in the floating wind sector, Pearson of Flotation Energy observed: ‘There’s a bit of a trade-off between innovation and cost reduction. We want to be innovative and bring down costs, but we want to be insurable at the same time. That’s why we see demonstration trials and the pre-commercial rig market as so important. There is a learning curve. If we can trial floating wind technology in small projects, and show them to be successful, it will give more certainty to the market.’

 

Suzanne Sasna, Director of Energy Transition at Scottish Enterprise, concluded: ‘Developing floating offshore wind is a global challenge. Generally, it requires collaboration by global contractors who are willing to share information. But the potential opportunity is enormous.’
