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.
- 3 is now Bellrock and 1,200 MW
- 8 is now Broadshore and 900 MW
- 10 is now Stromar and 1,000 MW
Falck Renewables, who have now been renamed Renantis, 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.
Three Shetland ScotWind Projects Announced
The title of this post, is the same as that of this press release on Crown Estate Scotland.
These three paragraphs outline how the leases were allocated.
Three projects will be offered seabed agreements for offshore wind projects following Crown Estate Scotland’s ScotWind clearing process.
The announcement comes as an offshore wind supply chain summit is held in Aberdeen today (22 August) with Sir Ian Wood, chaired by Michael Matheson MSP, Cabinet Secretary for Energy, and including a keynote address by First Minister Nicola Sturgeon MSP.
Clearing saw the ‘NE1’ area east of Shetland made available for ScotWind applicants who met the required standards but who did not secure their chosen location earlier in the leasing process.
I think it was good idea to offer these leases to those bidders that failed to get a lease, the first time around, despite meeting the standards.
- Would it encourage bidders, if they knew that after the expense of setting up a bid, that if they failed, they could have another chance?
- It must also save the Scottish Government time and money checking out bidders.
- How many times have you interviewed several applicants for a job and then found jobs for some of those, that you didn’t choose for the original job?
Let’s hope the philosophy has generated some good extra contracts.
This map from Cross Estate Scotland shows all the contracts.
Note the three new leases numbered 18, 19 and 20 to the East of Shetland, in the North-East corner of the map.
Their details are as follows.
- 18 – Ocean Winds – 500 MW
- 19 – Mainstream Renewable Power – 1800 MW
- 20 – ESB Asset Development – 500 MW
Note.
All are floating wind farms.
- Ocean Winds is a Spanish renewable energy company that is developing the Moray West and Moray East wind farms.
- Mainstream Renewable Power appear to be a well-financed and ambitious company, 75 % owned by Aker.
- ESB Energy appear to be an experienced energy company owned by the Irish state, who operate several wind farms and Carrington gas-fired power station in the UK.
2.8 GW would appear to be a generous second helping.
Ocean Winds and Mainstream Renewable Power
This web page on the Ocean Winds web site, is entitled Ocean Winds Designated Preferred Bidder For Seabed Leases For 2.3 GW Of Floating Projects East Of Shetland, Scotland, contains several snippets of useful information.
- Crown Estate Scotland announced the result of ScotWind Leasing round clearing process, awarding Ocean Winds with two seabed leases for floating offshore wind projects: a 1.8 GW capacity site with partner Mainstream Renewable Power, and another 500 MW capacity site, east of the Shetland Islands.
- Ocean Winds’ international portfolio of projects now reaches 14.5 GW of gross capacity, including 6.1 GW in Scotland.
- Floating wind turbines for the two adjacent sites are confirmed, because of the water depth.
- The partners are committed to developing floating offshore wind on an industrial scale in Scotland, generating local jobs and opportunities in Scotland and the Shetland Islands.
- From the picture on the web page, it looks like WindFloat technology will be used.
- Ocean Winds developed the WindFloat Atlantic project.
Ocean Winds appear to want to go places.
The Shetland HVDC Connection
The Shetland HVDC Connection will connect Shetland to Scotland.
- It will be 160 miles long.
- It will have a capacity of 600 MW.
- It is estimated that it will cost more than £600 million.
- It will allow the 66MW Lerwick power station to close.
- It will be completed in 2024.
I have a feeling that all these numbers don’t add up to a sensible answer.
Consider.
- The three offshore wind farms can generate up to 2800 MW of green electricity.
- With a capacity factor of 50 %, an average of 1400 MW of electricity will be generated.
- The Viking onshore wind farm on Shetland could generate up to 450 MW.
- More wind farms are likely in and around Shetland.
- Lerwick power station can probably power most of the Shetland’s needs.
- Lerwick power station is likely to be closed soon.
- Sullum Voe Terminal has its own 100 MW gas-turbine power station.
- Load is balanced on Shetland by 3MWh of advanced lead-acid batteries.
- Lerwick has a district heating scheme.
If we assume that Shetland’s energy needs are of the order of a few hundred MW, it looks like at times the wind farms will be generating more electricity, than Shetland and the Shetland HVDC Connection can handle.
Various plans have suggested building electrolysers on Shetland to create hydrogen.
Conversion of excess electricity to hydrogen, would have the following advantages.
- The hydrogen could be used for local heavy transport and to replace diesel.
- Hydrogen could be used to fuel a gas turbine back-up power station, when needed.
- Hydrogen could be used for rocket fuel, if use of Shetland as a Spaceport for launching satellites takes off.
Any excess hydrogen could be exported to the rest of the UK or Europe.
Bombora Wraps Tank Trials Of Its Floating Hybrid Energy Platform
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the introductory paragraph.
Bombora Wave Power has completed tank testing of its floating foundation system suitable for the InSPIRE solution, which combines the mWave wave energy technology with a wind turbine onto a single floating offshore platform.
This second paragraph gives details of the power output of the hybrid energy platform.
The tank testing program at FloWave follows the pre-FEED phase of the InSPIRE project completed earlier in 2022, based on the integration of a 4MW mWave solution with a 10MW wind turbine on a single semi-submersible floating foundation system.
4 MW seems a worthwhile increase in power, that can probably be handled by the existing cables and substations.
Equinor Is Counting On Tax Breaks With Plans For North Sea Oilfield
The title of this post, is the same as that, of this article in The Times.
These paragraphs outline the project.
Norway’s state-owned oil company is pushing ahead with plans to develop Britain’s biggest untapped oilfield after confirming that it stands to benefit from “helpful” tax breaks introduced alongside the windfall levy.
Equinor could lower its windfall tax bill by as much as £800 million in the years to come thanks to investment relief if it develops the Rosebank field, according to Uplift, a campaign group.
Rosebank, to the west of Shetland, could cost £4.1 billion to develop and may account for about 8 per cent of British oil output in the second half of this decade, producing 300 million barrels of oil by 2050.
Equinor said yesterday that it hoped to take a final investment decision on the field by next year and to start production by 2026. It has applied for environmental approval from the government.
Needless to say Greenpeace are not amused.
We Have Both Long Term And Short Term Energy Problems
In the UK, energy is generally used as electricity or gas and to power industry and transport.
Electricity
In the long term, we need to decarbonise our electricity production, so that all our electricity is produced from zero-carbon sources like nuclear, solar, tidal, wave and wind.
- As I write this, our electricity production is around 26.8 GW of which 62 % is coming from renewable sources.
- Surprisingly around 45 % of the renewables is coming from solar. Who’d have ever thought that in an predominantly-grey UK?
- As we have committed to around 50 GW of wind power by 2030 and the 3.26 GW Hinckley Point C will be on stream by the end of the decade, the long term future of electricity production looks to be fairly secure.
- It would be even more secure, if we added around 600 GWh of storage, as proposed in Highview Power’s Plan To Add Energy Storage To The UK Power Network, which would be used as backup when the sun doesn’t shine and the wind doesn’t blow.
It looks to me, that our long term electricity problem is capable of being solved.
For the next few years, we will need to rely on our existing gas-fired power stations until the renewables come on stream.
Gas
Gas could be more of a problem.
- I wouldn’t be surprised to see a lot of resistance to the replacement of natural gas for heating, cooking and industrial processes.
- Natural gas is becoming increasingly difficult to source.
- As I said in the previous section, we will still need some gas for electricity generation, until the massive wind farms are completed.
On the other hand, there is HyDeploy.
I like the HyDeploy concept, where up to 20 % of hydrogen is blended with natural gas.
- Using a blend of hydrogen and natural gas doesn’t require any changes to boilers, appliances or industrial processes.
- The hydrogen blend would make the most of our existing world class gas network.
- Customers do not require disruptive and expensive changes in their homes.
- Enormous environmental benefits can be realised through blending low carbon hydrogen with fossil gas.
- The hydrogen blending could happen, where the natural gas enters the network at terminals which receive gas from the UK continental shelf or where liquified natural gas is imported.
- Alternatively, it may be possible to surround a gas production platform with an offshore wind farm. This could enable hydrogen production and blending to be performed offshore.
The amount of gas we need would drop by twenty percent.
In The Mathematics Of Blending Twenty Percent Of Hydrogen Into The UK Gas Grid, I calculated that 148.2 tonnes per hour of hydrogen would be needed, to blend twenty per cent of hydrogen into UK natural gas supplies.
I also said this about the electricity needed.
To create 148.2 tonnes per hour of hydrogen would need 8,180.64 MW of electricity or just under 8.2 GW.
I also calculated the effect of the hydrogen on carbon dioxide emissions.
As twenty percent will be replaced by hydrogen, carbon dioxide emission savings will be 24,120,569.99 tonnes.
I believe that generating the 8.2 GW of electricity and delivering the 148.2 tonnes per hour of hydrogen is feasible.
I also believe that HyDeploy could be a valuable way to reduce our demand for natural gas by twenty per cent.
Transport
Not every vehicle, ship, aircraft and train can be powered by electricity, although batteries will help.
Hydrogen will help, but we must also develop our capability for sustainable fuels made from rubbish diverted from landfill and biologically-derived ingredients like used cooking oil.
Summing Up Our Long Term And Short Term Energy Problems
We obviously have got the problem of creating enough renewable energy for the future, but there is also the problem of how we keep everything going in the interim.
We will need gas, diesel, petrol and other fossil fuel derived products for the next few years.
Is Rosebank Our Short Term Solution?
This page on the Equinor web site is entitled Rosebank Oil And Gas Field.
This introductory paragraph described the field.
Rosebank is an oil and gas field 130 kilometres off the coast of the Shetland Islands. Equinor acquired the operatorship in 2019 and has since then been working to optimise and mature a development solution for the field together with our partners.
Could the field with its resources of oil and gas, be just the sort of field to tide us over in the next few difficult years.
But given the position, it will surely not be an easy field to develop.
These two paragraphs set out Equinor’s strategy in developing the field.
Equinor believes the field can be developed as part of the UK Government North Sea Transition deal, bringing much needed energy security and investment in the UK while supporting the UKs net zero target. According to a socioeconomic study (see link below) based on data and analysis by Wood Mackenzie and Voar Energy, if sanctioned Rosebank is estimated to create GBP 8.1 billion of direct investment, of which GBP 6.3 billion is likely to be invested in UK-based businesses. Over the lifetime of the project, Rosebank will generate a total of GBP 24.1 billion of gross value add (GVA), comprised of direct, indirect and induced economic impacts.
Equinor together with our partners are working with the supply chain to ensure that a substantial part of investment comes to Scotland and the UK. A supplier day was held in Aberdeen in partnership with EIC in order to increase the number of local suppliers to tender.
Note.
- The sums that could accrue to the UK economy are worthwhile.
- The Government North Sea Transition Deal is worth a read.
- A lot of the deal is about converting oil and gas skills to those of a renewable energy economy.
Planned properly, we should get all the oil and gas we need to get through difficult years.
I particularly like these two paragraphs, which are towards the end of the Government North Sea Transition Deal.
Through the Deal, the UK’s oil and gas sector and the government will work together to deliver
the skills, innovation and new infrastructure required to decarbonise North Sea oil and gas
production as well as other carbon intensive industries. Not only will it transform the sector in
preparation for a net zero future, but it will also catalyse growth throughout the UK economy.
Delivering large-scale decarbonisation solutions will strengthen the position of the existing UK
energy sector supply chain in a net zero world, securing new high-value jobs in the UK,
supporting the development of regional economies and competing in clean energy export
markets.
By creating the North Sea Transition Deal, the government and the UK’s oil and gas sector are
ambitiously seeking to tackle the challenges of reaching net zero, while repositioning the UK’s
capabilities to serve the global energy industry. The Deal will take the UKCS through to
maturity and help the sector pivot towards new opportunities to keep the UK at the forefront of
the changing 21st century energy landscape.
I believe that developing Rosebank could enable the following.
- The oil and gas we need in the next few years would be obtained.
- The economic situation of the UK would be improved.
- The skills and techniques we need to decarbonise the UK would be delivered.
- Net-zero would be reached in the required time.
- Jobs will be created.
- The export of surplus oil and gas.
I strongly believe that developing the Rosebank field would be worthwhile to the UK.
I have some other thoughts.
Electrification Of Platforms
This page on the Equinor web site is entitled Electrification Of Platforms.
This paragraph explains what that means.
Electrification means replacing a fossil-based power supply with renewable energy, enabling a reduction in greenhouse gas emissions. Equinor is fully committed to reducing emissions from our offshore oil & gas production.
Note.
- Typically, platforms use gas turbine engines running on natural gas to provide the electricity needed on the platform.
- Platforms in the future will get their electricity from renewable sources like wind and will have an electricity cable to the shore.
- Rosebank will be powered in this way.
This document on the Equinor web site is entitled Rosebank: Investing In Energy Security And Powering A Just Transition, which has a section called How Is Rosebank Different?, where this is said.
The key difference of Rosebank compared to other oil fields is that it
aims to draw on new technology applications to help reduce carbon
emissions from its production, through FPSO electrification.Building offshore installations that can be powered by electricity reduces
reliance on gas powered generators which are the biggest source
of production emissions. The electrification of UKCS assets is vital to
meeting the North Sea Transition Deal’s target of reducing production
emissions by 50% by 2030, with a view to being net zero by 2050.Electrification of Rosebank is a long-term investment that will drastically
cut the carbon emissions caused by using the FPSO’s gas turbines for
power. Using electricity as a power source on Rosebank results in a
reduction in emissions equivalent to taking over 650,000 cars off the
road for a year compared with importing 300 million barrels of oil from
international sources.
Note.
- An FPSO is a Floating Production Storage And Offloading Unit, which is the method of production, that Equinor have chosen for the Rosebank field.
- If we are going to extract fossil fuels then we must extract them in a manner, that doesn’t add to the problem by emitting extra carbon dioxide.
- We will probably extract fossil fuels for some years yet, as they are the easiest route to some important chemicals.
- I also believe that we will increasingly find uses for any carbon dioxide captured in combustion and chemical processes.
I already know of a farmer, who heats greenhouses using a gas-powered combined heat and power unit, who pipes the carbon dioxide to the tomatoes in the greenhouses.
Despite what Greenpeace and others say, carbon dioxide is not all bad.
Energy Security
The last page of this document on the Equinor web site is entitled Rosebank: Investing In Energy Security And Powering A Just Transition, is entitled Energy Security.
Look at the numbers.
- £8.1 billion – Total field investment with 78% of this being spent in the UK
- 1600 – Estimated peak number of direct FTE jobs
- £24.1 billion – Estimated gross value add
- 8 % – Of UK oil production from Rosebank to 2030
- 39 million cubic feet per day – Average daily gas production over the first 10 years of field life, equivalent to almost twice Aberdeen’s daily gas consumption
- 250kt CO2 – Carbon avoided by reusing existing FPSO
And if you have time read it fully.
Could The Rosebank FPSO Be Powered By Floating Offshore Wind?
Floating wind turbines are now being installed around the world.
- They can use the largest turbines.
- Some designs perform in the roughest of seas.
- They have a high capacity factor.
- They are generally brought into a suitable port for servicing and updating.
- Floating wind farms can be connected to floating substations
There is at least 20 GW of floating wind turbines planned for UK waters.
So could an appropriately-sized floating wind farm be placed near the Rosebank FPSO to provide it with electricity?
I don’t see why not, if there were some energy storage in the system, for when the wind wasn’t blowing.
Floating Offshore Wind Close To The Rosebank FPSO Would Be Challenging
Rosebank is an oil and gas field 130 kilometres off the West coast of the Shetland Islands.
That would be a challenging location for floating wind turbines.
But solving the installation problems would set precedents for floating wind farms all over the world.
Could The Rosebank FPSO Handle Hydrogen From Floating Offshore Wind?
It would surely be possible to put an electrolyser in the system somewhere, so that hydrogen was also stored in the tanks of the FPSO.
I also don’t think it unfeasible, that twenty percent of hydrogen could be blended into the natural gas to create the low-carbon natural gas, that has been proposed by the HyDeploy project.
Boris Baldrick’s Cunning Plan
This written statement to Parliament on the UK Government web site, is entitled Transport Update: Transpennine Route Upgrade.
It has been published by Grant Shapps and this is the sub-title.
Additional funding has been made available for the Transpennine route upgrade.
This is the complete statement.
Today 19 July 2022, the government has made available £959 million of additional funding to continue to progress the delivery of the ambitious Transpennine route upgrade.
This funding is a significant milestone and another step towards upgrading the key east-west rail artery across the north of England, to further this government’s levelling up and decarbonisation objectives.
In addition to progressing the design of aspects of the upgrade, this funding will enable further on-the-ground delivery of electrification and journey time improvement works, mostly west of Leeds.
One of the first tangible benefits will be enabling electric trains to run between Manchester and Stalybridge by the middle of the decade. We are also developing scope that will enable the Transpennine route upgrade to become the first phase of Northern Powerhouse Rail, including plans to unlock freight flows and take thousands of lorries off our roads.
We are also more than trebling the investment in the Transpennine route upgrade from £2.9 billion to between £9.0 billion and £11.5 billion.
This additional investment will enable the roll out of digital signalling technology, electrification of the full route and the provision of additional tracks for commercial and freight services, giving rail users more reliable, more punctual, more comfortable and greener rail journeys.
I have some thoughts.
It’s Not A Wish List, But A Reality
The last paragraph reads like a wish list.
This additional investment will enable the roll out of digital signalling technology, electrification of the full route and the provision of additional tracks for commercial and freight services, giving rail users more reliable, more punctual, more comfortable and greener rail journeys.
But it’s not a wish list, it’s what is to be done.
Where Will The Government Get Between Nine and Eleven-And-A-Half Billion Pounds?
It’s not the sort of small change that you have in a sock draw.
This document on the UK government web site, is entitled PM Opening Remarks At Press Conference With German Chancellor Olaf Scholz: 8 April 2022, where this is these three paragraphs.
We will also agree on the importance of weaning ourselves off dependence on Russian gas and oil, and ensuring that our energy security cannot be threatened by a rogue state.
This is not easy for any of us, and I applaud the seismic decisions taken by Olaf’s government to move Germany away from Russian hydrocarbons.
Today we have agreed to maximise the potential of the North Sea and collaborate on energy security and on renewables, where Germany and the UK lead the way in new technology.
So did Boris and Olaf sign the world’s first Green Alliance based on zero-carbon energy?
- They may not have signed an Alliance, but they have agreed on common actions.
- Over the last year or so, German money and technology has started to be more visible in our offshore wind farms.
- BP have been backed by German utility; enBW in some of their huge wind farms.
- Siemens Gamesa are providing a lot of wind turbines.
- Will German shipyards build the floats for floating wind farms?
- An interconnector between the Isle of Grain and Wilhelmshaven is planned.
- Rolls-Royce and its German subsidiary MTU are charging into battle against climate change.
- The Germans have taken a liking to ITM Power’s electrolysers to produce hydrogen.
I can see the North Sea or the German Ocean becoming Europe’s power station, with by 2030, a large amount of the energy not needed by the UK, being exported to the Continent, either as electricity or hydrogen.
The Germans could become our magische Geldbäume.
But unlike gas and oil, wind power in the North Sea won’t run out, as it’s renewable.
In How Britannia With Help From Her Friends Can Rule The Waves And The Wind, this was my conclusion.
Boris’s vision of the UK becoming a Saudi Arabia of wind is no fantasy of a man with massive dreams.
Standard floating wind turbines, with the possibility of also harvesting wave power could be assembled in ports along the coasts, towed into position and then connected up.
Several GW of wind-power capacity could probably be added each year to what would become the largest zero-carbon power station in the world.
By harvesting the power of the winds and waves in the seas around the British Isles it is an engineering and mathematical possibility, that could have been developed by any of those great visionary Victorian engineers like Armstrong, Bazalgette, Brunel and Reynolds, if they had had access to our modern technology.
Up Yours! Putin!
This energy and the money it provides will finance our infrastructure and our tax cuts.
Hexicon Wins UK’s First Ever CfD Auction For Floating Offshore Wind
The title of this post, is the same as that of this press release from Hexicon.
This is the first paragraph.
Today (7th of July) the UK Government confirmed that Hexicon AB’s TwinHub project in the Celtic Sea was successful in the latest Contracts for Difference (CfD) Allocation Round (AR4). It has been awarded a CfD for its 32MW floating wind project at a strike price of £87.30/MWh (2012 real prices) taking the project a significant step closer to completion.
This image shows one of their TwinHub turbine installations being towed into place.
The TwinHub home page has a title of The First Floating Offshore Wind Project in The Celtic Sea.
This is the description on the page.
The TwinHub offshore wind demonstration project intends to prove how Hexicon’s innovative design with two turbines on one floating foundation can further reduce the Levelized Cost of Energy (also referred to as LCoE) before large scale commercialisation. The TwinHub project is a stepping stone to help kick-start floating wind in the Celtic Sea, an area identified as a hotspot for floating wind by the UK Government. It will pave the path for larger and larger projects to help support The Crown Estates’ ambitious target of 4GW of floating wind in the Celtic Sea.
Scroll the page down and there is a short video of a pair of wind turbines in operation.
- It appears that when there is no wind, it automatically goes into a safe parked mode.
- As the wind rises, one turbine starts up.
- The second turbine starts up and the float turns so they face the wind.
It appears to be a classic example of disruptive innovation.
I did the calculations for floating and reusable oil and gas platforms in the 1970s, that were designed by two Cambridge University professors, which would have been launched horizontally and upturned when in position. This experience leads me to believe that the Swedish designers of this type of platform have been able to verify that this is a workable design.
This document from the Department of Business, Industry and Industrial Strategy indicates that the demonstration is for 32 MW.
Does that indicate, that this installation is twin 16 MW wind turbines?
16 MW seems to be the size of the largest wind turbines in the world.
There is a lot to like about this Swedish design.
- As the video shows, it appears to balance itself with the wind.
- I suspect from the calculations I did in Cambridge, that the twin design with its higher weight is more stable than a floating single turbine design.
- The float and its two turbines can be assembled alongside a dock with a large stable onshore dockside crane.
- Servicing would also be done in a dock.
- Working onshore is much safer and easier, than working offshore.
- The twin design allows more power to be generated in a given area of sea.
This is a brilliant concept and it will give Putin, the Sheikhs and the other oil dictators, the most terrible of nightmares.
The initial site chosen for this design in the UK, will be in the sea at Hayle in Cornwall.
This map shows the location.
Hayle is in the North-East corner of the map, by the sandy beach.
A 32 MW turbine could probably provide enough electricity for 15,000 houses.
The Crown Estate Announces Areas Of Search To Support Growth Of Floating Wind In The Celtic Sea
The title of this post, is the same as that of this press release from the Crown Estate.
This is the first paragraph.
In a major step forward in supporting the UK’s net zero ambitions, The Crown Estate has today identified five broad ‘Areas of Search’ for the development of floating offshore wind in the Celtic Sea – a region rich in natural resources, including world-class wind resource that can be developed with floating turbines. This marks a significant milestone and provides the foundation on which to build greater capacity in the future, helping the UK to achieve its renewable energy targets and drive economic development.
Points in the press release include.
- Five areas with good wind power potential have been chosen.
- A competitive tender, is to be launched in mid-2023.
- It is intended that these areas will deliver 4GW of floating offshore wind power by 2035.
This map shows the areas.
I have a few thoughts.
What About The Other Wind Farms Already Announced In the Celtic Sea?
In DP Energy And Offshore Wind Farms In Ireland, I said this.
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.
So what about these seven wind farms?
Erebus and Valorus
Is Blue Gem’s philosophy to develop and prove the technology and put in big bid for around a GW?
Gwynt Glas
The Gwynt Glas web site says this.
The Crown Estate announced in March 2021 that it intends to run a competitive leasing round to award seabed rights to developers for floating offshore wind (FLOW) projects in the Celtic Sea, targeting an overall regional capacity of 4GW.
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 partnership project is called Gwynt Glas, Welsh for Blue Wind, in recognition of its Celtic roots.
Our proposed floating offshore wind project could provide power for approximately 920,000 homes.
It looks like they’re throwing their hat into the ring for 1 GW.
Llŷr Wind
The Llŷr Wind web site says this.
Combined, the two 100MW projects will generate enough renewable electricity to power around 250,000 homes. If successful, we will be able to offer highly cost-effective, floating offshore wind farms to the rest of the world by 2030.
By unlocking new, higher energy capacities from deeper waters, further offshore, the Llŷr projects have huge implications for UK energy consumers. Not only will they help the UK meet its target for net zero emissions, but they will create new opportunities for regional manufacturing and supply chains in Wales and Southwest England as global demand for floating, offshore, wind rises.
It looks to me that this project hasn’t been fully defined yet. Perhaps, this will happen after a successful bid.
Llywelyn
The Llywelyn web site says this.
Llywelyn wind farm is located in Welsh waters in the Celtic Sea, 40 miles off the coast of Pembrokeshire.
Llywelyn’s location has been selected following an extensive feasibility study and rigorous site assessment process. Our assessment has included reviews of protected areas, environmental impacts, cable routing, existing infrastructure, marine traffic, and fishing activity.We have signed an agreement with National Grid, securing a 300MW grid connection in Pembrokeshire. The system operator is exploring upgrades to the existing site to facilitate the connection. These developments will enable the Llywelyn offshore wind project to quickly enter the planning system.
Have they already said go?
Petroc
The Petroc web site says this.
Petroc’s location has been selected following an extensive feasibility study and rigorous site assessment process. Our assessment has included reviews of protected areas, environmental impacts, cable routing, existing infrastructure, marine traffic, and fishing activity.
We have signed an agreement with National Grid, securing a 300MW grid connection in North Devon. The system operator is exploring upgrades to the existing site to facilitate the connection. These developments will enable the Petroc offshore wind project to quickly enter the planning system.
Have they already said go?
These companies are certainly setting themselves up for bidding or have already got a smaller deal.
How Much Wind Power Can Be Developed In The Celtic Sea?
This article on the Engineer is entitled Unlocking The Renewables Potential Of The Celtic Sea.
The article starts with these two paragraphs.
Over the last decade, the UK has become a global leader in renewable marine energy, tapping into the vast resources its coastal geography offers. Offshore wind, in particular, has flourished, with gigawatt-scale projects being deployed off the east coast of England and Scotland, at Hornsea, Dogger Bank and Moray.
However, looking at a map of existing and proposed wind farms, what’s perhaps most striking is the complete absence of projects in the southwest of Britain, off the rugged shores of Wales, Devon and Cornwall, shaped by the fierce North Atlantic. 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. What’s more, it also delivers some of the highest tidal ranges in the world, alongside some of the best waters in Europe for generating wave energy. In a country blessed with renewable resources, the Celtic Sea may well be its biggest prize.
I’ll go along with what this article says and accept that 50 GW of wind capacity could be installed in the Celtic Sea.
As I write this article at around nine o’clock, the UK is generating almost exactly 30 GW of electricity, which gives an idea of how large electricity production in the Celtic Sea could be.
Conclusion
It will be interesting to see how this first round of leasing in the Celtic Sea develops.
XLCC Obtains Planning Approval To Build UK’s First HVDC Cable Factory In North Ayrshire
The title of this post, is the same as that of this press release from XLCC.
These are the first three paragraphs.
On 29th June 2022, the North Ayrshire Council Planning Committee resolved to grant planning permission for XLCC’s HVDC subsea cable manufacturing operations in Hunterston, Scotland.
Breaking ground in the coming months, the brownfield site will create a new UK industry to support global decarbonisation targets. Once fully operational, the facility will support 900 jobs in the area, with thousands more in the wider supply chain.
XLCC’s first order is for four 3,800km long cables to connect solar and wind renewable power generation in the Sahara to the UK for the Xlinks Morocco-UK power project.
XLCC have also issued two other important press releases.
XLCC To Build New Cable Laying Vessel To Address Increase In Future Demand For HVDC Cable
These are the first paragraphs.
XLCC, the new HVDC, renewable energy focused business in the UK, has completed the concept design of an advanced, first-of-a-kind Cable Laying Vessel to be delivered in the first half of 2025.
As the world strives for Net Zero, the UK, EU and other world economies have set themselves ambitious targets for decarbonisation. The UK, for example, has stated that it will be powered entirely by clean energy by 2035 and that it will fully decarbonise the power system in the same time frame. This ambition is driving an exponential growth in high voltage cable demand as the increase in installation of offshore wind and interconnectors drive a forecast six times increase (2020 – 2027 over 2014 – 2020) for HVDC cable.
The planned delivery of the XLCC CLV will support the Morocco – UK Power Project, the first client project, through the delivery of four 3,800km subsea HVDC cables from a wind and solar generation site in Morocco to the UK.

XLCC Signs UK Steel Charter For New Export-Led Cable Industry
These are the first paragraphs.
XLCC signed the UK Steel Charter at an event in Parliament on 19 April 2022, alongside representatives from politics, business and the trade union movement.
XLCC will create a new export-led HVDC cable manufacturing industry for the UK, nearly doubling the world’s current production. It aims to support renewable energy projects with the first factory planned for Hunterston, Scotland. XLCC will deliver its first project for the Xlinks Morocco-UK Power Project, consisting of four 3,800km long subsea cables, with the first phase between 2025-2027 connecting wind and solar power generated in Morocco exclusively to the UK in Devon.
Signing the UK Steel Charter shows a commitment to supporting existing and future jobs within the sector and the supply chain. Along with strengthening UK-based business, sourcing steel locally will cut transport emissions and seek to support decarbonisation in a sector dedicated to finding ways to minimise environmental impact of steel use.
This press release can be read in full here.
I have a few thoughts.
You Wait For A Large Interconnector Project To Come Along And Then Two Arrive Holding Hands
This paragraph introduces the Morocco-UK Power Project.
The Xlinks Morocco-UK Power Project will be a new electricity generation facility entirely powered by solar and wind energy combined with a battery storage facility. Located in Morocco’s renewable energy rich region of Guelmim Oued Noun, it will cover an approximate area of 1,500km2 and will be connected exclusively to Great Britain via 3,800km HVDC sub-sea cables.
XLCC have this mission statement on their home page.
XLCC will establish a new, export-led, green industry in the UK: world class HVDC subsea cable manufacturing.
Our mission is to provide the connectivity required for renewable power to meet future global energy needs.
Xlinks Morocco-UK Power Project and XLCC appear to be made for each other.
In some ways it takes me back to the 1970s, where large oil and gas projects in the North Sea were paired with platform building in Scottish lochs.
There Are Several Interconnector Projects Under Development
We will see a lot of undersea interconnectors in the next few years.
- Country-to-country interconnectors
- Interconnectors along the coast of the UK.
- Connections to offshore wind farms.
This capacity, with a ship to lay it, is being created at the right time.
Icelink
Icelink is a proposed interconnector between Iceland and the UK.
- It would be up to 1200 km long.
- It would have a capacity of around 1 GW
XLCC could spur the development of this project.
Floating Wind Farms Hundreds Of Miles Out To Sea
The developer of a floating wind farm, say a hundred miles out to sea, is not going to develop it, if there isn’t a secure supply of cable.
Where Will Finance Come From?
Wind farms have proven to be good investments for finance giants such as Aviva.
See World’s Largest Wind Farm Attracts Huge Backing From Insurance Giant, for Aviva’s philosophy.
As mathematical modelling for electrical systems get better, the estimates of the finance needed and the returns to be made, will indicate whether these mega-projects can be funded.
It was done with North Sea oil and gas and it can be done with offshore wind power and its interconnectors.
In The Times on the 4th of July 2022, there is this article, which is entitled Schroders Chief Buzzing To Take Finance Offshore Wind Farms.
It is a must-read!
Conclusion
XLCC and its cable factory will spur the expansion of zero-carbon electricity in the UK.
Could Rolls-Royce SMRs Be The Solution To Europe’s Gas Shortage?
Of all the offshore wind farms, that I’ve looked at recently, I find Magnora’s ScotWind N3 wind farm the most interesting.
I wrote about it in ScotWind N3 Offshore Wind Farm.
I said this.
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 very much like the idea of a concrete floater, which contains a huge electrolyser and gas storage, that is surrounded by an armada of giant floating wind turbines.
These are my thoughts.
Floating Concrete Structures
To many, they may have appear to have all the buoyancy of a lead balloon, but semi-submersible platforms made from concrete have been used in the oil and gas industry for several decades.
Kishorn Yard in Scotland was used to build the 600,000-tonne concrete Ninian Central Platform,in 1978. The Ninian Central Platform still holds the record as the largest movable object ever created by man.
The Ninian Central Platform sits on the sea floor, but there is no reason why a semi-submersible structure can’t be used.
Electrolysers
There is no reason, why a large electrolyser, such as those made by Cummins, ITM Power or others can’t be used, but others are on the way.
- Bloom Energy are working on high temperature electrolysis, which promises to be more efficient.
- Torvex Energy are developing electrolysis technology that used sea water, rather than more expensive purified water.
High Temperature Electrolysis
High temperature electrolysis needs a heat source to work efficiently and in Westinghouse And Bloom Energy To Team Up For Pink Hydrogen, I described how Bloom Energy propose to use steam from a large nuclear power station.
Offshore Nuclear Power
I’ve never heard of offshore nuclear power, but it is not a new idea.
In 1970, a company called Offshore Power Systems was created and it is introduced in its Wikipedia entry like this.
Offshore Power Systems (OPS) was a 1970 joint venture between Westinghouse Electric Company, which constructed nuclear generating plants, and Newport News Shipbuilding and Drydock, which had recently merged with Tenneco, to create floating nuclear power plants at Jacksonville, Florida.
Westinghouse’s reactor was a 1.150 MW unit, which was typical of the time, and is very similar in size to Sizewell B.
The project was cancelled before the reactors were towed into position.
Nuclear Knowledge Has Improved
Consider.
- In the fifty years since Offshore Power Systems dabbed their toes in the water of offshore nuclear power, our knowledge of nuclear systems and engineering has improved greatly.
- The offshore oil and gas industry has also shown what works impeccably.
- The floating offshore wind industry looks like it might push the envelop further.
- There has been only one nuclear accident at Fukushima, where the sea was part of the problem and that disaster taught us a lot.
- There have been a large number of nuclear submarines built and most reached the planned end of their lives.
- Would a small modular nuclear reactor, be safer than a large nuclear power plant of several GW?
I would suggest we now have the knowledge to safely build and operate a nuclear reactor on a proven semi-submersible platform, built from non-rusting concrete.
An Offshore Wind Farm/Small Modular Reactor Combination Producing Hydrogen
Consider.
- A typical floating offshore wind farm is between one and two gigawatts.
- A Rolls-Royce small modular reactor is sized to produce nearly 0.5 GW.
- The high temperature electrolyser will need some heat to achieve an optimum working temperature.
- Spare electricity can be used to produce hydrogen.
- Hydrogen can be stored platform.
- Hydrogen can be sent ashore using existing gas pipes.
- Hydrogen could even be blended with natural gas produced offshore to create a lower-carbon fuel.
- It would also be possible to decarbonise nearby offshore infrastructure.
A balance between wind and nuclear power can be obtained, which would provide a steady output of energy.
Conclusion
There are a large numbers of possibilities, to locate a Rolls-Royce small modular reactor close to a wind farm to use high temperature electrolysis to create green hydrogen, which can be used in the UK or exported through the gas network.
Equinor And Partners Consider 1 GW Offshore Wind Farm Off The Coast Of Western Norway
The title of this post, is the same as that of this press release from Equinor.
This is the first paragraph.
Equinor and its partners Petoro, TotalEnergies, Shell and ConocoPhillips in the Troll and Oseberg fields, have initiated a study and are looking into possible options for building a floating offshore wind farm in the Troll area some 65 kilometres west of Bergen, Norway.
This second paragraph describes the production and use of the electricity.
With an installed capacity of about ~1 GW and an annual production of ~4.3 TWh, with a startup in 2027, Trollvind could provide much of the electricity needed to run the offshore fields Troll and Oseberg through an onshore connection point. The Bergen area already serves several of these installations with power – and needs more input to its electricity grid. The plan is that the partnership will buy as much energy as the wind farm can produce at a price that can make the project possible.
The press release includes a map of the wind farm, the oil and gas fields and Bergen.
This is not the first time, I’ve heard of plans to use wind-generated electricity to power offshore oil and gas fields.
It could be argued that if the gas is sold to the UK or Germany, then that country is responsible for the carbon emissions.
I doubt that Vlad the Mad’s bloodstained gas is produced using a carbon-free process.
