The Anonymous Widower

13 Offshore Wind Projects Selected In World’s First Innovation And Targeted Oil & Gas Leasing Round

The title of this post, is the same as that of this article on offshoreWIND.biz.

This is the sub-heading.

Crown Estate Scotland has selected 13 out of a total of 19 applications with a combined capacity of around 5.5 GW in the world’s first leasing round designed to enable offshore wind energy to directly supply offshore oil and gas platforms.

This paragraph outlines INTOG (Innovation and Targeted Oil & Gas) and its objectives.

INTOG, which has been designed in response to demand from government and industry to help achieve the targets of the North Sea Transition Sector Deal through decarbonising North Sea oil and gas operations, is also expected to further stimulate innovation in Scotland’s offshore wind sector, create additional supply chain opportunity, assist companies to enter the renewable energy market, and support net-zero ambitions.

This is undoubtedly the most important news of the day.

  • When complete it will generate 5416 MW of electricity.
  • 4068 MW will be used primarily to decarbonise oil and gas platforms with surplus electricity going to the grid.
  • The amount of carbon dioxide released by oil and gas platforms in the North Sea will be reduced.
  • The gas saved by decarbonising oil and gas platforms, will be transported to the shore and used in the UK gas grid.
  • 449 MW will be generated in innovative ways in small wind farms, with a capacity of less than 100 MW.

One of the benefits of INTOG is that the UK will be able to reduce gas imports, which must increase energy security.

This map from this document from the Crown Estate Scotland, shows the INTOG wind farms.

This is a list of the farms.

  • 1 – Bluefloat Energy/Renantis Partnership – Innovation – Commercial – 99.45 MW
  • 2 – Bluefloat Energy/Renantis Partnership – Innovation – Supply Chain – 99.45 MW
  • 3 – Simply Blue Energy (Scotland) – Innovation – Supply Chain – 100 MW
  • 4 – BP Alternative Energy Investments – Innovation – New Markets – 50 MW
  • 5 – ESB Asset Development – Innovation – Cost Reduction – 100 MW
  • 6 – Floatation Energy – Targeted Oil & Gas – 560 MW
  • 7 – Cerulean Winds – Targeted Oil & Gas – 1008 MW
  • 8 – Harbour Energy – Targeted Oil & Gas – 15 MW
  • 9 – Cerulean Winds – Targeted Oil & Gas – 1008 MW
  • 10 – Cerulean Winds – Targeted Oil & Gas – 1008 MW
  • 11 – Floatation Energy – Targeted Oil & Gas – 1350 MW
  • 12 – TotalEnergies – Targeted Oil & Gas – 3 MW
  • 13 – Harbour Energy – Targeted Oil & Gas – 15 MW

Note.

  1. The five Innovation sites seem to be as close to the coast as is possible.
  2. I thought some Innovation sites would be closer, so supply difficult to reach communities, but they aren’t.
  3. Floatation Energy and Cerulean Winds seemed to have bagged the lion’s share of the Targeted Oil & Gas.
  4. Sites 6 and 7 sit either side of a square area, where Targeted Oil & Gas will be considered. Is that area, the cluster of oil and gas facilities around Forties Unity, shown on the map in this page on the BP web site?
  5. Harbour Energy have secured two 15 MW sites for Targeted Oil & Gas.

These are my thoughts on the various companies.

Bluefloat Energy

Bluefloat Energy has posted this press release on their web site, which is entitled Bluefloat Energy | Renantis Partnership Bid Success For Two 99mw Innovation Projects In Crown Estate Scotland’s INTOG Process.

The press release starts with these three bullet points.

  • BlueFloat Energy | Renantis Partnership offered exclusivity rights to develop its Sinclair and Scaraben floating wind projects north of Fraserburgh – leveraging synergies via its 900MW Broadshore project.
  • The projects seek to trial innovative floating wind technology solutions, kick-starting supply chain growth and job creation in Scotland and providing a ‘stepping-stone’ to the partnership’s ScotWind projects.
  • Bid proposals include the intention to develop a scalable community benefit model – creating a potential blueprint for floating offshore wind in Scotland.

The first three paragraphs expand the bullet points.

The BlueFloat Energy and Renantis Partnership has been offered seabed exclusivity rights to develop two 99MW projects under the innovation arm of Crown Estate Scotland’s INTOG (Innovation and Targeted Oil & Gas) auction process. The auction saw ten projects bid to bring forward the development of small-scale innovation projects.

The Sinclair and Scaraben projects, located north of Fraserburgh and adjacent to the Partnership’s 900MW Broadshore project, seek to trial innovative foundation technologies, associated fabrication works and mooring systems with a view to maximising opportunities for the Scottish supply chain, driving local investment and job creation.

A key element of the bid proposals is the opportunity to test and adapt a community benefit model, governed independently, and directed by the communities in which the schemes will operate, through collaboration with our supply chain and project partners. The model could create a blueprint, shaping the future of community benefit from floating offshore wind throughout the whole of Scotland. This builds on Renantis’ successful track record of deploying similar schemes via its onshore wind farms in Scotland.

Note.

  1. Companies called Sinclair Offshore Wind Farm and Scaraben Offshore Wind Farm were registered a few months ago in Inverness.
  2. I couldn’t find the websites, so I suspect they’re still being created.
  3. These two projects appear to be pathfinders for the 900 MW Broadshore project, with regards to the supply chain and community involvement.

It certainly looks like the partnership are going about the development of these two projects in a professional manner.

BP Alternative Energy Investments

There has been no press release from BP as I write this, so I will have to deduce what BP are planning.

This map from this document from the Crown Estate Scotland, shows the Southern INTOG wind farms.

Note.

  1. Site 4 is the site of BP Alternative Energy Investments’s proposed wind farm.
  2. Sites 6 and 7 could be either side of the cluster of platforms around Forties Unity.

Consider.

  • In the wider picture of wind in the North Sea, BP’s proposed 50 MW wind farm is a miniscule one. SSE Renewables’s Dogger Bank wind farm is over a hundred times as large.
  • A cable to the shore and substation for just one 50 MW wind farm would surely be expensive.
  • BP Alternative Energy Investments are also developing a 2.9 GW wind farm some sixty miles to the South.
  • It would probably be bad financial planning to put large and small wind farms so close together.

For these are other reasons, I believe that there is no reason to believe that the proposed 50 MW wind farm is a traditional wind farm.

But if I’m right about sites 6 and 7 indicating the location the position of Forties Unity, it might open up other possibilities.

This document from INEOS, who own the Forties Pipeline System, explains how the pipeline works.

The Forties Pipeline System (FPS) is an integrated oil and gas transportation and processing system. It is owned and operated by INEOS and utilises more than 500 miles of pipeline to smoothly transport crude oil and gas from more than 80 offshore fields for processing at the Kinneil Terminal. At Kinneil the oil and gas are separated, with the oil returned as Forties Blend to customers at Hound Point or pumped to the Petroineos refinery at Grangemouth.
At the same time the gas goes to our LPG export facilities or is supplied to the INEOS petrochemical plant. FPS transports around 40% of the UK’s oil production supply and brings over 400,000 barrels ashore every day.

In Can The UK Have A Capacity To Create Five GW Of Green Hydrogen?, I said the following.

Ryze Hydrogen are building the Herne Bay electrolyser.

  • It will consume 23 MW of solar and wind power.
  • It will produce ten tonnes of hydrogen per day.

The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.

If BP were to pair the wind farm with a  50 MW electrolyser it will produce 21.7 tonnes of hydrogen per day.

Could it be brought to the shore, by linking it by a pipeline to Forties Unity and then using the Forties Pipeline System?

As the category on site 4, is New Markets, are BP and INEOS investigating new markets for hydrogen and hydrogen blends?

  • Some of the latest electrolysers don’t need pure water and can use sea water. This makes them more affordable.
  • Do BP and/or INEOS have the capability to extract the hydrogen as it passes through the Cruden Bay terminal, to provide the hydrogen for Aberdeen’s buses and other users?
  • INEOS and BP probably have some of the best oil and gas engineers in the world.
  • How many other places in the world have an offshore oil or gas field set in a windy sea, where floating wind- turbine/electrolysers could generate hydrogen and send it ashore in an existing pipeline?
  • Several of these offshore oil and gas fields and the pipelines could even be owned by BP or its associates.
  • Remember that hydrogen is the lightest element, so I suspect it could be separated out by using this property.

This BP site, is to me, one of the most interesting of the successful bids.

  • BP probably have a large collection of bonkers ideas, that have been suggested during their long involvement with offshore oil and gas.
  • Some ideas could be even suggested by employees, whose fathers worked for BP fifty years ago. I’ve met a few BP employees, whose father also did.
  • Will the wind farm, be a floating electrolyser at the centre of a cluster of a few large floating turbines?
  • Will each turbine have its own electrolyser and the substation only handle hydrogen?
  • Will the floating electrolyser have hydrogen storage?
  • Have BP got a floating or semi-submersible platform, that could either go to the breakers or be repurposed as the floating electrolyser?
  • Repurposing a previous platform, would make all the right noises.

So many possibilities and so far, no clues as to what will be built have been given.

Further Thoughts On BP’s Successful INTOG Bid

Cerulean Winds

In What Is INTOG?, I said this about Cerulean Winds.

Cerulean sounds like it could be a sea monster, but it is a shade of blue.

This article on offshoreWind.biz is entitled Cerulean Reveals 6 GW Floating Offshore Wind Bid Under INTOG Leasing Round.

These are the two introductory paragraphs.

Green energy infrastructure developer Cerulean Winds has revealed it will bid for four seabed lease sites with a combined capacity of 6 GW of floating wind to decarbonise the UK’s oil and gas sector under Crown Estate Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round.

This scale will remove more emissions quickly, keep costs lower for platform operators and provide the anchor for large-scale North-South offshore transmission, Cerulean Winds said.

Note.

    1. It is privately-funded project, that needs no government subsidy and will cost £30 billion.
    2. It looks like each site will be a hundred turbines.
    3. If they’re the same, they could be 1.5 GW each.
    4. Each site will need £7.5 billion of investment. So it looks like Cerulean have access to a similar magic money tree as Kwasi Kwarteng.

Effectively, they’re building four 1.5 GW power stations in the seas around us to power a large proportion of the oil and gas rigs.

For more on Cerulean Winds’s massive project see Cerulean Winds Is A Different Type Of Wind Energy Company.

So does it mean, that instead of 6 GW, they were only successful at three sites and the other or others were in the six unsuccessful applications?

There is a press release on the Cerulean Winds web site, which is entitled Cerulean Winds Wins Bid For Three INTOG Floating Wind Sites, where this is said.

Cerulean Winds and Frontier Power International have been awarded three lease options for the Central North Sea in the highly competitive INTOG leasing round, the results of which were announced by Crown Estate Scotland today.

The sites, in the Central North Sea, will enable the green infrastructure developer and its partners to develop large floating offshore windfarms to decarbonise oil and gas assets. The scale of the development will enable a UK wide offshore transmission system, that can offer green energy to offshore assets in any location and create a beneficial export opportunity.

Nothing about unsuccessful applications was said.

This map from this document from the Crown Estate Scotland, shows the Southern INTOG wind farms.

Note.

  1. Sites 7, 9 and 10 are Cerulean’s sites.
  2. Sites 6 and 11 are Floatation Energy’s sites.
  3. Site 4 is BP Alternative Energy Investments’s Innovation site.
  4. Sites 8, 12 and 13 are much smaller sites.

It looks like Cerulean and Floatation Energy are well-placed to power a sizeable proportion of the platforms in the area.

ESB Asset Development

ESB Asset Development appear to be a subsidiary of ESB Group.

The ESB Group is described like this in the first paragraph of their Wikipedia entry.

The Electricity Supply Board is a state owned (95%; the rest are owned by employees) electricity company operating in the Republic of Ireland. While historically a monopoly, the ESB now operates as a commercial semi-state concern in a “liberalised” and competitive market. It is a statutory corporation whose members are appointed by the Government of Ireland.

This press release, is entitled ESB Offered Exclusive Rights To Develop Innovative 100MW Floating Offshore Wind Project In The Malin Sea.

These two paragraphs outline the project.

ESB today welcomes the outcome of Crown Estate Scotland’s latest seabed leasing process which has resulted in the offer of exclusive development rights to ESB for a 100MW floating wind project in Scottish waters off the north coast of Northern Ireland. The successful project, Malin Sea Wind, is a collaborative bid between ESB and leading technology developers Dublin Offshore Technology and Belfast-based CATAGEN. The outcome underscores ESB’s growing capabilities and expanding presence in the offshore wind industry.

The Innovation and Targeted Oil and Gas (INTOG) seabed leasing process, run by Crown Estate Scotland, aims to drive cost reduction in the offshore wind sector by enabling the deployment of new and innovative technologies, and to harness wind energy to decarbonize the oil and gas sector. Malin Sea Wind aims to support the reduction of floating offshore wind costs by demonstrating Dublin Offshore’s patented load-reduction technology. Furthermore, the project will support decarbonisation of the aviation sector by powering sustainable aviation fuel (SAF) production technology currently under development by net-zero technology specialists, CATAGEN.

Note.

  1. I’ve just looked at the Technology page of the Dublin Offshore Technology web site.
  2. In the 1970s, I built large numbers of mathematical models of steel, concrete and water cylinders in my work with a Cambridge University spin-out called Balaena Structures.
  3. I believe, that an experienced mathematically modeller could simulate this clever system.

That would prove if it works or not!

This Google Map shows the Malin Sea.

Note.

  1. Malin Head is marked by the red arrows on the Northern Irish coast.
  2. The most Westerly Scottish island is Islay and the most Easterly is the Isle of Arran.
  3. Between the two islands is the Kintyre peninsula.
  4. Portrush can be picked out on the Northern Irish coast.

By overlaying the two maps, I suspect the centroid of the wind farm will be North of Portrush about a few miles North of the Southern end of Arran.

I suspect that if all goes well, there could be a lot of floating wind turbines in the area.

This Google Map shows the River Foyle estuary and Foyle Port to the North-East of Londonderry/Derry.

Note.

  1. Coolkeeragh ESB and Lisahally biomas power station on the South bank of the River Foyle.
  2. Lisahally biomas power station has a capacity of 16 MW.
  3. There appears to be a large substation at Coolkeeragh ESB.
  4. A tanker of some sort seems to be discharging.

Until told, I’ve guessed wrong, it looks to me like Coolkeeragh ESB could be the destination for the electricity generated by Malin Sea Wind. Given that this project’s aim is cost reduction, a 100 MW wind farm could make a difference.

In addition could Foyle Port be used to assemble and maintain the floating turbines?

Floatation Energy

Floatation Energy have posted this press release on their web site, which is entitled Flotation Energy and Vårgrønn Awarded Exclusivity To Develop Up To 1.9 GW Of Floating Offshore Wind In Scotland.

The first part of the press release, has a graphic.

It shows how their proposed system will work.

  • A floating wind farm will be placed between the shore and oil and gas platforms to be decarbonised.
  • The wind farm will be connected to the shore by means of a bi-directional cable, so that the wind farm can export electricity to the grid and when the wind isn’t blowing the grid can power the platforms.
  • A cable between the wind farm and the platforms completes the system.

It is a simple system, where all elements have been built many times.

Floatation Energy must have been fairly confident that their bids would be successful as they have already named the farms and set up web sites.

The websites are very informative.

The Timeline for 2019-2021 on the Green Volt web site describes the describes the progress so far on the project.

2019 – As construction of the Kindardine offshore floating wind farm kicks off, Flotation Energy identifies the Buzzard oil facility (a relatively new oil and gas platform with a long field life and high electrical load) as the optimal starting point for a significant contribution to the North Sea Transition Deal – the process of replacing large scale, inefficient gas-fired power generation with renewable electricity from offshore wind.

2020 – Flotation Energy begins environmental surveys on the Ettrick/Blackbird oil field, a redundant site nearby Buzzard, which is in the process of decommissioning. The “brownfield” site is confirmed as an exceptional opportunity to create an offshore floating wind farm, with water depths of 90-100m and high quality wind resource.

2021 – Flotation Energy works with regulators to understand the potential for project “Green Volt” to decarbonise offshore power generation for Buzzard. Flotation Energy completes and submits an Environmental Scoping report to Marine Scotland, reaching the first major milestone in the Marine Consent process. Crown Estate Scotland announces a new leasing round for Innovation and Targeted Oil and Gas Decarbonisation (INTOG).

On a section on the Cenos web site, there is a section called Efficient Grid Connection, where this is said.

The power generated by the wind turbines will be Alternating Current (AC) and routed to a substation platform. AC power will be exported to the oil and gas platforms.

For efficient export to the UK grid, the substation platform will include a converter station to change the AC power to Direct Current (DC) before the power is transported to shore. This is due to transporting AC power over long distances leading to much of the power being lost.

Cenos is working in partnership with the consented NorthConnect interconnector project, to utilise their DC cable routing where possible. Cenos will also use the NorthConnect onshore converter station planned for Fourfields near Boddam, which then has an agreed link into the Peterhead Substation. This collaboration minimises the need to construct additional infrastructure for the Cenos project.

That all sounds very practical.

Note.

  1. Floatation Energy delivered the Kincardine offshore floating wind farm.
  2. Both wind farms appear to use the same shore substation.
  3. Buzzard oil field is being expanded, so it could be an even more excellent oil field to decarbonise.
  4. NorthConnect is a bit of an on-off project.

Floatation Energy seem to have made a very professional start to the delivery of their two wind farms.

Harbour Energy

The Wikipedia entry for Harbour Energy describes the company like this.

Harbour Energy plc is an independent oil and gas company based in Edinburgh, Scotland. It is the United Kingdom’s largest independent oil and gas business. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.

But if you look at news items and the share price of the company, things could look better for Harbour Energy.

On their map of UK operations, I can count nearly twenty oil and gas fields.

As they have other oil and gas fields around the world, decarbonisation of their offshore operations could increase production by a few percent and substantially cut their carbon emissions.

That is a philosophy that could be good for profits and ultimately the share price.

So has the company gone for a very simple approach of two identical floating wind turbines?

They have been successful in obtaining leases for sites 8 and 13.

  • Both have a capacity of 15 MW, so are the farms a single 15 MW wind turbine?
  • I think this is likely, unless it is decided to opt for say a 16 MW turbine.
  • Or even a smaller one, if the platform is in a bad place for wind.
  • The wind turbine would be parked by the platform to be decarbonised and connected up, to a simple substation on the platform.
  • I would recommend a battery on the platform, so that if the wind wasn’t blowing, power was still supplied to the platform.
  • There would be no need for any cable between shore and wind farm and the only substation, would be a relatively simple one with a battery on the platform.

It could be a very efficient way of decarbonising a large number of platforms.

Once Harbour Energy have proved the concept, I could build a simple mathematical model in Excel, to work out any change in profitability and carbon emissions for a particular oil or gas platform.

Who Is Britannia Ltd?

In this document from the Crown Estate Scotland, there is a section that gives the partners in each project.

Listed for site 8 are Chrysaor (U.K.) and Britannia Limited and for site 13 is Chryasaor Petroleum Company UK Limited.

This page on the Harbour Energy web site gives the history of Chrysaor and Harbour Energy.

This is the heading.

Chrysaor was founded in 2007 with the purpose of applying development and commercial skills to oil and gas assets and to realise their value safely.

This is the history.

The Group grew rapidly over the years through a series of acquisitions. With backing from Harbour Energy – an investment vehicle formed by EIG Global Energy Partners – Chrysaor acquired significant asset packages in the UK North Sea from Shell (2017) and ConocoPhillips (2019) to become the UK’s largest producer of hydrocarbons.

In 2021, Chrysaor merged with Premier Oil to become Harbour Energy plc.

So that explains the use of the Chrysaor name or Chryasaor as someone misspelt it on the Crown Estate Scotland document.

I asked myself, if Britannia Ltd. could be a technology company, so I checked them out. The only company, I could find was a former investment trust, that was dissolved over ten years ago.

But Britannia is an oil and gas field in the North Sea, which is partially owned by Harbour Energy. It has a page on Harbour Enerrgy’s web site, which is entitled Greater Britannia Area.

This is said about the Britannia field.

Britannia in Block 16/26 of the UK central North Sea sits approximately 210-kilometres north east of Aberdeen. The complex consists of a drilling, production and accommodation platform, a long-term compression module of mono-column design and a 90-metre bridge connected to a production and utilities platform. Britannia is one of the largest natural gas and condensate fields in the North Sea. Commercial production began in 1998. Condensate is delivered through the Forties Pipeline to the oil stabilisation and processing plant at Kerse of Kinneil near Grangemouth and natural gas is transported through a dedicated Britannia pipeline to the Scottish Area Gas Evacuation (SAGE) facility at St Fergus.

Looking at the maps on the Crown Estate Scotland, Harbour Energy and others, it looks like site 8 could be close to the

Greater Britannia Area or even the Britannia field itself.

Simply Blue Energy

Simply Blue Energy are developing the 100 MW Salamander wind farm.

I wrote about this project in The Salamander Project.

Did it get chosen, as it was a project, where the design was at an advanced stage?

TotalEnergies

I wouldn’t be surprised to find out that TotalEnergies have gone a very similar route to Harbour Energy, but they are trying it out with a 3 MW turbine.

Conclusion

They are an excellent group of good ideas and let’s hope that they make others think in better and move innovative ways.

Politics will never save the world, but engineering and science just might!

Stromar, Broadshore And Bellrock

The ScotWind wind farms, that I described in ScotWind Offshore Wind Leasing Delivers Major Boost To Scotland’s Net Zero Aspirations, are starting to be more than numbers in documents.

This map shows the various ScotWind leases.

 

Note, that the numbers are Scotwind’s lease number in their documents.

Falck Renewables and BlueFloat Energy are involved in all three projects, with Ørsted also involved in Stromar.

This article on Renewable Energy Magazine is entitled Companies Partner on Floating Offshore Wind In Scotland, where this is said.

Together the three areas could accommodate a total of approximately 3.0 GW of offshore wind capacity, with the projects scheduled to be operational by the end of the decade, subject to securing consent, commercial arrangements and grid connections.

Dates for ScotWind seem to be emerging and 2030 seems to cover several.

DP Energy And Offshore Wind Farms In Ireland

DP Energy are a company that are developing these offshore wind farms in Ireland.

Clarus Offshore Wind Farm

Located off the West Coast of Ireland, the Clarus Offshore Wind Farm project will utilise Floating Offshore Wind (FOW) technology and upon completion, will have the potential capacity of up to 1 GW.

Inis Ealga Marine Energy Park

Located off the South Coast of Ireland, the Inis Ealga Marine Energy Park project will utilise Floating Offshore Wind (FOW) technology and upon completion, will have the potential capacity of up to 1 GW.

Latitude 52 Offshore Wind Farm

DP Energy has given the name Latitude 52 to the area it is exploring for a potential future offshore wind farm off the coast of Counties Wicklow and Wexford.

It appears to be another 1 GW project.

Shelmalere Offshore Wind Farm

Located off the East Coast of Ireland, the Shelmalere Offshore Windfarm project will utilise fixed bottom wind turbines and upon completion, will have the potential capacity of up to 1 GW.

Note.

  1. These wind farms are being developed in a partnership with Spanish Energy company; Iberdrola.
  2. Each is a one GW offshore wind farm.

They are also developing the Gwynt Glas offshore wind farm in the UK sector of the Celtic Sea.

  • In January 2022, EDF Renewables and DP Energy announced a Joint Venture partnership to combine their knowledge and
    expertise, in order to participate in the leasing round to secure seabed rights to develop up to 1GW of FLOW in the Celtic Sea.
  • The wind farm is located between Pembroke and Cornwall.

The addition of Gwynt Glas will increase the total of floating offshore wind in the UK section of the Celtic Sea.

  • Blue Gem Wind – Erebus – 100 MW Demonstration project  – 27 miles offshore
  • Blue Gem Wind – Valorus – 300 MW Early-Commercial project – 31 miles offshore
  • Falck Renewables and BlueFloat Energy – Petroc – 300 MW project – 37 miles offshore
  • Falck Renewables and BlueFloat Energy – Llywelyn – 300 MW project – 40 miles offshore
  • Llŷr Wind – 100 MW Project – 25 miles offshore
  • Llŷr Wind – 100 MW Project – 25 miles offshore
  • Gwynt Glas – 1000 MW Project – 50 miles offshore

This makes a total of 2.2 GW, with investors from several countries.

It does seem that the Celtic Sea is becoming the next area of offshore wind around the British Isles to be developed.

Interconnectors

Interconnectors are to be built to connect Ireland, UK and France.

The Celtic Interconnector is being built between County Cork in Ireland and the North West Coast of France.

Greenlink is being built between County Wexford in Ireland and Pembroke in Wales.

Conclusion

Are the British, Irish and French governments, planning to build a large wind power resource in the Celtic Sea?

Two Celtic Sea Floating Wind Projects Could Be Delivered By 2028

The title of this post, is the same as that of this article on offshoreWIND.biz.

This is the first paragraph.

Falck Renewables and BlueFloat Energy have said that they are looking at early delivery of their two floating wind projects in the Celtic Sea, called Llywelyn and Petroc, which have grid connections secured and almost a year’s worth of bird surveys already completed.

These would add two extra 300 MW wind farms to the Celtic Sea.

In Enter The Dragon, I indicated the potential of renewable energy around Wales based on this article on the Engineer is entitled Unlocking The Renewables Potential Of The Celtic Sea. This sentence from the article talks about the possibilities of offshore wind in the Celtic Sea.

The Celtic Sea – which extends south off Wales and Ireland down past Cornwall and Brittany to the edge of the continental shelf – is estimated to have around 50GW of wind generating capacity alone.

The article also talks about Blue Gem Wind and their Erebus and Valorous wind farm projects in the Celtic Sea, that I wrote about in Blue Gem Wind.

There now appears to be four floating wind farms under development in the Celtic Sea between the South-West corner of Wales and the Devon and Cornwall Peninsular.

  • Blue Gem Wind – Erebus – 100 MW Demonstration project  – 27 miles offshore
  • Blue Gem Wind – Valorus – 300 MW Early-Commercial project – 31 miles offshore
  • Falck Renewables and BlueFloat Energy – Petroc – 300 MW project – 37 miles offshore
  • Falck Renewables and BlueFloat Energy Llywelyn – 300 MW project – 40 miles offshore

But they do create a starter for a GW.

Both consortia seem to have similar objectives.

  • To use a stepping-stone approach, gradually building in size.
  • To involve the local community in creating a supply chain.
  • Create long-term benefits for the region.

If these and other consortia fill the Celtic Sea with 50 GW of floating wind turbines, then we’ll all benefit.

ScotWind Offshore Wind Leasing Delivers Major Boost To Scotland’s Net Zero Aspirations

The title of this post, is the same as that of this press release on the Crown Estate Scotland web site.

This is the first two paragraphs.

Crown Estate Scotland has today announced the outcome of its application process for ScotWind Leasing, the first Scottish offshore wind leasing round in over a decade and the first ever since the management of offshore wind rights were devolved to Scotland.

The results coming just months after Glasgow hosted the global COP26 climate conference show the huge opportunity that Scotland has to transform its energy market and move towards a net zero economy.

Some highlights are then listed.

  • 17 projects have been selected out of a total of 74 applications.
  • A total of just under £700m will be paid by the successful applicants in option fees and passed to the Scottish Government for public spending.
  • The area of seabed covered by the 17 projects is just over 7,000km2.
  • Initial indications suggest a multi-billion pound supply chain investment in Scotland
  • The potential power generated will move Scotland towards net-zero.

This map shows the position of each wind farm.

Note, that the numbers are Scotwind’s lease number in their documents.

Fixed Foundation Wind Farms

These are the six fixed foundation wind farms.

  • 1 – BP Alternative Energy Investments – 859 km² – 2.9 GW
  • 6 – DEME – 187 km² – 1.0 GW
  • 9 – Ocean Winds – 429 km² – 1.0 GW
  • 13 – Offshore Wind Power – 657 km² – 2.0 GW
  • 16 – Northland Power – 161 km² – 0.8 GW
  • 17 – Scottish Power Renewables – 754 km² – 2.0 GW

Adding up these fixed foundation wind farms gives a capacity of 9.7 GW in 3042 km² or about 3.2 MW per km².

Floating Wind Farms

These are the ten floating wind farms.

  • 2- SSE Renewables – 859 km² – 2.6 GW
  • 3 – Falck Renewables Wind – 280 km² – 1.2 GW
  • 4 – Shell – 860 km² – 2.0 GW
  • 5 – Vattenfall – 200 km² – 0.8 GW
  • 7 – DEME Concessions Wind – 200 km² – 1.0 GW
  • 8 – Falck Renewables Wind – 256 km² – 1.0 GW
  • 10 – Falck Renewables Wind – 134 km² – 0.5 GW
  • 11 – Scottish Power Renewables – 684 km² – 3.0 GW
  • 12 – BayWa r.e. UK  – 330 km² – 1.0 GW
  • 14 – Northland Power – 390 km² – 1.5 GW

Adding up the floating wind farms gives a capacity of 14.6 GW in 4193 km² or about 3.5 MW per km².

Mixed Wind Farms

This is the single wind farm, that has mixed foundations.

15 – Magnora – 103 km² – 0.5 GW

This wind farm appears to be using floating wind turbines.

I have a few general thoughts.

Are Floating Wind Farms Further Out?

There does appear to be a pattern, where the wind farms that are further from the land tend to be floating wind farms and those closer to the land appear to be fixed.

Consider.

  • As the water gets deeper, fixed wind turbines will surely get more expensive.
  • Floating wind turbines are the newer and more unproven technology, so only those bidders, who have done their research and are happy with it, will have bid.

Falck Renewables Wind Seem To Be Working With BlueFloat Energy

In the three Falck Renewables successes with leases 3, 8 and 10, BlueFloat Energy is a partner in the lease.

According to their web site, BlueFloat Energy were very much involved in WindFloat Atlantic, where this is said.

Top members of our team were key contributors to the development and construction of the WindFloat Atlantic project from concept to Final Investment Decision to commissioning. This 25 megawatt (MW) floating offshore wind project in Portugal marked a turning point in the offshore wind industry as it was the first floating offshore wind project to secure bank financing. With 3 x MVOW’s 8.4 MW turbines, the WindFloat Atlantic project was the world’s first semi-submersible floating wind project and continental Europe’s first floating wind project.

So do Falck Renewables intend to use WindFloat technology in their areas, which are to produce a total of 2.7 GW?

Perhaps a fleet of two hundred floating wind turbines based on WindFloat technology each with a capacity of 14 MW would be ideal.

  • Wind turbines would be interchangeable between all three farms.
  • There could be a few standby turbines to allow for maintenance.
  • It would be possible to borrow a turbine to explore a new site.

All it would need is technology to be able to position and connect a turbine into the wind farm and disconnect and remove a turbine from the wind farm, with simple procedures.

Did BP Avoid the Floating Wind Farms?

BP, who are relatively new to offshore wind, only had one success, for a large fixed wind farm. So did they avoid the floating wind farms?

Do Shell and Scottish Power Have A Bigger Plan? 

Shell and Scottish Power were successful with leases 4 and 11, which are reasonably close together.

They also won lease 17, which I wrote about in MacHairWind Wind Farm, where I concluded this.

The MacHairWind wind farm seems a well-positioned wind farm.

  • It is close to Glasgow.
  • It can be used in tandem with the Cruachan pumped hydro power station.
  • It will have access to the Western HVDC Link to send power to the North-West of England.

Is Scotland replacing the 1.2 GW Hunterston B nuclear power station with a 2 GW wind farm, with help from Cruachan and other proposed pumped storage hydro schemes to the North of Glasgow?

So did Shell and Scottish Power get the pick of the bunch and will build two large floating wind farms close together?

Shell and Scottish Power seem to be using French company; Eolfi’s floating wind technology.

Why Do Floating Wind Farms Have A Higher Density?

The floating wind farms have an average energy density of 3.5 MW per sq. km, whereas the fixed wind farms only manage 3.2 MW per sq. km.

It may be only ten percent, but does that help the economics? It certainly, wouldn’t make them worse.

I do wonder though, if the reason for the higher density is simply that a floating turbine can be bigger, than a corresponding fixed turbine.

I also have a few more specific thoughts about individual farms.

Lease 15 – The Odd Bid Out

In any design competition, there is usually at least one design, that is not look like any of the others.

In the successful bids for the ScotWind leases, the bid from Magnora ASA stands out.

  • The company has an unusual home page on its offshore wind web site.
  • This page on their web site outlines their project.
  • It will be technology agnostic, with 15MW turbines and a total capacity of 500MW
  • It will use floating offshore wind with a concrete floater
  • It is estimated, that it will have a capacity factor of 56 %.
  • The water depth will be an astonishing 106-125m
  • The construction and operation will use local facilities at Stornoway and Kishorn Ports.
  • The floater will have local and Scottish content.
  • The project will use UK operated vessels​.
  • Hydrogen is mentioned.
  • Consent is planned for 2026, with construction starting in 2028 and completion in 2030.

This project could serve as a model for wind farms all round the world with a 500 MW power station, hydrogen production and local involvement and construction.

I discuss this project in more detail in ScotWind N3 Offshore Wind Farm.

A Conclusion About Floating Wind

The various successful bids in this round of Scottish wind farm leases can be split by capacity into two groups.

  • Floating + Mixed – 15.1 GW – 61 %
  • Fixed – 9.7 GW – 39 %

Note that I have included Magnora’s successful mixed bid with the successful floating bids, as it uses floating wind turbines to generate electricity.

The over 60 % of successful bids involving floating wind farms, indicates to me, that the day of floating wind farms has arrived.
