Rishi Sunak To Reimpose Fracking Ban
The title of this post, is the same as that of this article on The Telegraph.
This is the first paragraph.
The new PM made the commitment during his first session of PMQs on Wednesday, reversing Liz Truss’s controversial decision to overturn it.
I think it is the right call.
Here’s why!
Cerulean Winds Massive Decarbonisation Project
Consider.
- At present ten percent of our gas is used to power the oil and gas rigs in the seas around our coasts. The gas is fed into gas-turbines to generate electricity.
- One simple way to increase gas production by this ten percent, would be to decarbonise the rigs by powering them from nearby wind farms with green electricity and green hydrogen as the Norwegians are proposing to do.
- A British company; Cerulean Winds has proposed under the Crown Estate INTOG program to decarbonise a significant part of the oil and gas rigs, by building four 1.5 GW wind farms amongst the rigs.
- The majority of the energy will be sold to the rig owners and any spare electricity and hydrogen will be brought ashore for industrial and domestic users.
- This massive project will be a privately-funded £30 billion project.
- And when the oil and gas is no longer needed, the UK will get another 6 GW of offshore wind.
We need more of this type of engineering boldness.
This page on the Cerulean Winds web site gives more details.
INTOG
This document on the Crown Estate web site outlines INTOG.
Other Projects
Decarbonisation has also attracted the attention of other developers.
I can see Rishi Sunak being offered several projects, that will increase our oil and gas security, by some of the world’s best engineers and most successful oil companies.
Rishi Sunak’s ban on fracking will only increase the rate of project development.
We live in extremely interesting times.
Simply Blue Group And Marine Power Systems To Pursue INTOG Innovation Project Opportunity
The title of this post, is the same as this of this press release from Simply Blue Group.
These two paragraphs explain the proposals.
Marine Power Systems (MPS) have partnered with Simply Blue Group to develop a project proposal for the Innovation and Targeted Oil and Gas (INTOG) leasing round run by Crown Estate Scotland.
The collaboration between Simply Blue Group and MPS would see six wind turbines deployed on the MPS floating platform, PelaFlex, in waters between 60 and 100m in depth, delivering a total capacity of 100MW.
The INTOG proposal, that I outlined in What Is INTOG?, seems to have got engineers and financiers thinking.
Simply Blue Group are quoted saying this about the PelaFlex platform.
MPS has been selected as the preferred technology partner based on the strengths of their structurally efficient tension legged platform which delivers significantly reduced system mass and a smaller mooring footprint than its peers. The technology has been designed to optimise local content delivery through a decentralised logistics model, and those benefits help utility scale developers minimise costs whilst maximising local economic benefits and accelerating industrial scale farm development.
That sounds good to me!
There is also more on the PelaFlex web page including a video.
The Turbine Size
The press release talks of six turbines totalling up to 100 MW, which is probably around 17 MW per wind turbine.
These are no ordinary wind turbines!
About INTOG
The press release also says this about INTOG.
The INTOG leasing round aims to support projects that will directly reduce emissions from oil and gas production (up to a total capacity of 5.7GW) but also drive commercialisation and innovation in offshore wind (up to a total capacity of 500MW) as well as support supply chain development. This forms part of the Scottish Government’s drive to reach net zero emissions by 2045 where the decarbonisation of oil and gas installations is seen as playing an important role in the transition to net zero.
Decarbonisation of our oil and gas fields, will obviously be a good thing because of a reduction of the carbon dioxide emitted. but it will also mean that the gas that would have been used to power the platform can be brought ashore to power industry and domestic heating, or be exported to countries who need it.
Conclusion
INTOG seems to be a good idea, as it is provoking new and innovative designs.
Harbour Energy
This article in The Times in the Tempus column is entitled Oil And Gas Producer Harbour Energy Offers Safe Haven.
This is the first paragraph.
Booming commodity prices mean Harbour Energy is throwing off cash and yet the biggest oil and gas producer in the UK North Sea is still struggling to gain credibility in the eyes of investors.
Reading the column, it does seem a bit of a paradox, when the author says.
- London-listed oil and gas companies are cheap.
- Harbour Energy is in the bargain basement.
- The share price doesn’t reflect the P/E ratio.
- The company seems to have the money for acquisitions.
- It doesn’t seem to have taken advantage of the Ukraine situation.
- Revenues should transform its cash flow position.
The author finishes by recommending to buy the shares.
In Cerulean Winds Is A Different Type Of Wind Energy Company, I introduced Cerulean Winds and their £30 billion plan to decarbonise much of North Sea oil and gas production. This sensational plan is described in full on this page of their web site, which is entitled The Cerulean Winds Intog Scheme.
It strikes me that Harbour Energy could be the sort of energy company that could benefit from Cerulean Winds’s scheme.
- It could increase their gas production by ten percent.
- Harbour Energy probably have the money to decarbonise.
- Would decarbonising their North Sea operations improve the company’s profile?
I will certainly watch for any links between the two companies.
Cerulean Winds Is A Different Type Of Wind Energy Company
I introduced Cerulean Winds in a post called What Is INTOG?, but I have decided it is too important a concept to be buried in another post.
Cerulean sounds like it could be a sea monster, but it is actually 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.
- It is privately-funded project, that needs no government subsidy and will cost £30 billion.
- It looks like each site will be a hundred turbines.
- If all the sites are the same, they could be 1.5 GW each, with the use of 15 MW turbines.
- 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.
This paragraph describes their four hundred floating bases.
The steel floating bases would constitute hundreds of thousands of tonnes of steel, which unlike cement fixtures, can be floated out from shore which is said to be ideal for the UK.
Building those bases, is a very large project.
On their web site, Cerulean Winds have a page entitled Targeted Oil And Gas Decarbonisation.
This the page’s mission statement.
Cerulean Winds, a green energy & infrastructure developer, is leading a pioneering bid to reduce carbon emissions from oil and gas production through floating offshore wind.
These three paragraphs describe the scheme.
Cerulean Winds pioneering bid proposes an integrated floating wind and hydrogen development across four offshore floating wind farms located West and East of the Shetland Islands and in the North and the South of the Central North Sea (CNS). The objective of the project is to generate electricity from floating wind farms located far offshore on otherwise unallocated and uneconomic seabed areas in order to power oil and gas platforms with green energy.
Cerulean Winds’ dedicated power transmission network will offer both green electrons and green molecules to oil & gas production facilities across the UK Continental Shelf (UKCS) with surplus energy used in the production of green hydrogen. This dual approach allows the project to support all ages of oil and gas platforms with constant, reliable power and minimal brownfield modifications.
The optimised scale at which Cerulean Winds’ proposed scheme operates makes it the world’s largest decarbonisation project. It offers green energy to operators for asset power generation, delivered through an affordable Power Purchase Agreement (PPA). Another big advantage is the scheme does not require any public subsidies, but funded entirely through private investment.
That is sensational.
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.
I do have some thoughts.
Who Pays For This Massive Project?
This project overview on the Cerulean web site is entitled The Cerulean Winds INTOG Scheme and it gives many more details of the project.
I will refer to this page as the project overview in the subsequent text.
This is the first sentence of the first paragraph.
Our basin-wide scheme represents more than £30 billion of private investment in a single strategic infrastructure project.
Consider.
- The London Olympics in 2012 cost £9 billion.
- The Elizabeth Line will probably cost around £20 billion.
- The Channel Tunnel in 1994 cost £9 billion.
This project is a lot bigger than these.
Will your spare fifty pounds, still be in your mattress, when Cerulean Winds has put its £30 billion together?
I think so, as this is the last sentence on the page.
The scheme is ‘private wire’ and will not require Government subsidies… being funded entirely through private investment, with no cost to the tax payer.
There will of course, be tax rebates available, as they are for any business from the smallest to the largest.
Green Hydrogen Will Be Produced Offshore
The project overview says this about green hydrogen.
The scheme would use floating offshore wind to power oil and gas assets with surplus energy converted into green hydrogen. Cerulean Winds recognise each brownfield site has a different set of requirements and this would give operators the flexibility to electrify some Brownfield assets without the need to interrupt existing production or shutdown. It would also safeguard oil and gas jobs and create new green energy jobs within the floating wind and hydrogen sectors within the next five years.
The operator will have a choice of energy – electricity or hydrogen.
How Will The Project Earn An Income?
It appears that the project, will have a number of income streams.
The main stream, is described in this sentence from the project overview on the web site.
We have a deep understanding across the energy sector and will partner with the operator to agree the best way to achieve decarbonisation targets at the lowest possible cost. Our approach offers both green electrons and green molecules to the platforms through an affordable Power Purchase Agreement (PPA).
It looks like the oil and gas companies that own the rigs will be significant contributors to Cerulean’s cash flow.
Green electrons (electricity) and green molecules (hydrogen) will also be brought ashore and sold to various operators and the grid.
What Happens To The Gas That Is Currently Used To Power The Oil And Gas Rigs?
I do wonder, the gas, which will no longer be needed to power the rigs will give a boost to the supply to UK consumers.
They’ve thought of that one.
Under a heading of Reducing Gas Imports, this is said.
The project also aims to maximise recovery of energy from offshore platforms. With few exceptions, each platform have their own gas turbines for power generation, burning gas extracted from the reservoirs. Approximately 10% of the gas produced each year is used in offshore power generation. By replacing the need for gas power generation with a supply of clean, green energy, Cerulean Winds’ project frees important volumes of gas produced by platforms for consumption and reduces the UK’s import of gas from overseas.
This project, when it is fully implemented could increase UK gas production by up to ten per cent.
What’s In It For The Rig Operators?
They will have some benefits.
- They will cut their carbon dioxide emissions.
- They will sell about ten percent more of the gas they extract.
- Decarbonisation will not necessarily mean large capital expenditure on the rig.
- I also suspect, that some conveniently-placed rigs will be used to send excess hydrogen from Cerulean Winds’ electrolysers to the shore.
Some rig operators will make money from decarbonisation.
When Will The Project Be Complete?
This is the first paragraph on the project overview.
Our basin-wide scheme represents more than £30 billion of private investment in a single strategic infrastructure project. The locations will be West and East of the Shetland Islands and in the Central North Sea (CNS). They will become operational by 2028.
So we don’t have to wait for ever!
What Happens To Cerulean’s Project, When The Oil And Gas Runs Out Or We Stop Using Oil And Gas?
There would now be four 1.5 GW wind farms in the North Sea, that could be connected to the National Grid.
Conclusion
It looks like Cerulean Winds are a very different energy company.
Accelerating The Delivery Of Offshore Wind Farms
It is one of Kwasi Kwarteng’s ambitions to accelerate the delivery of offshore wind farms.
In The Growth Plan 2022, these groups of wind farms are mentioned.
- Remaining Round 3 Projects
- Round 4 Projects
- Extension Projects
- Scotwind Projects
- INTOG Projects
- Floating Wind Commercialisation Projects
- Celtic Sea Projects
My thinking in this post, will probably apply to all of these groups.
These are my thoughts.
Accelerating Delivery Of A Wind Farm
This will have these positive effects.
- Electricity will be delivered earlier.
- Customers will have a more secure supply of electricity.
- The wind farm owner will start to be paid for their electricity.
- The Crown Estate will start to be paid for their leases. Although, these might start at signing.
- National Grid will be paid for the transmission of the electricity.
- An energy storage company could be paid for storing surplus electricity.
- Construction teams and engineers can move on to the next project.
- Expensive construction hardware like ship-mounted cranes will no longer be needed.
- I also suspect that the government will raise some taxes from the various companies involved.
It looks like it’ll be winners all round.
How Will Delivery Be Accelerated?
These are some thoughts.
Overall Project Time
In How Long Does It Take To Build An Offshore Wind Farm?, I came to these conclusions.
- It will take six years or less from planning consent to commissioning.
- It will take two years or less from the start of construction to commissioning.
I suspect that as we have been building offshore wind farms for some years, that it will be very difficult to reduce these times significantly.
But as some wind farms take quite a few years to progress from the initial proposal to planning consent, I suspect that improvements to the planning process may speed up the overall construction time of a wind farm.
Project And Resource Management
Good project and resource management will always help.
Better Design And Construction Methods
I always remember in the early days of North Sea Oil, being told by a very experienced project manager that construction of production platforms was accelerated by the availability of larger and more powerful cranes.
Are we approaching the design of the ultimate wind farm? I doubt it, as in the last few months, I’ve seen two very radical new designs.
In Hexicon Wins UK’s First Ever CfD Auction For Floating Offshore Wind, I show this image of 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 fascinating 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 have a feeling that this type of installation might have generation, assembly and cost advantages over a single turbine mounted on a single float.
RCAM Technologies are also creating interesting designs for mounting turbines and energy storage using 3D-printed concrete.
What Ts The UK Government Doing To Accelerate Projects?
This article on offshoreWIND.biz, was published in late September 2022 and is entitled BREAKING: UK Puts Massive Amount Of New Offshore Wind Capacity On Fast Track and this is the first paragraph.
The UK will speed up planning and development consent processes for projects from the recently completed, currently ongoing, and upcoming (floating) offshore wind leasing rounds to bring new energy capacity online faster and facilitate economic growth and job creation.
The article is based on what Kwasi Kwateng said on the 23rd of September about speeding up projects in the 2022 Growth Plan.
A Quick Summary Of Our Wind Energy
The article has this paragraph, which summarises our wind energy.
For the UK, which currently has around 14 GW of offshore wind capacity in operation and 8 GW under construction, the projects from the listed auction rounds could bring well beyond the targeted capacity for 2030, which was recently raised to 50 GW.
I can see the target being raised again to at least 60 GW.
An Update To Will We Run Out Of Power This Winter?
My Methods
Project Timescales For Wind Farms
In How Long Does It Take To Build An Offshore Wind Farm?, I came to these conclusions.
- It will take six years or less from planning consent to commissioning.
- It will take two years or less from the start of construction to commissioning.
I shall use these timescales, as any accelerations by the government, will only reduce them.
Dates
If a date is something like 2024/25, I will use the latest date. i.e. 2025 in this example.
The Update
In Will We Run Out Of Power This Winter?, which I wrote in July this year, I did a calculation of how much renewable energy would come on stream in the next few years.
I summarised the amount of new renewable energy coming on stream like this.
- 2022 – 3200 MW
- 2023 – 1500 MW
- 3024 – 2400 MW
- 2025 – 6576 MW
- 2026 – 1705 MW
- 2027 – 7061 GW
This totals to 22442 MW.
But I had made two omissions.
- Hornsea 3 wind farm will add 2582 MW in 2026/27.
- Hinckley Point C nuclear power station will add 3260 MW in 2027.
Ørsted have also brought forward the completion date of the Sofia wind farm to 2023, which moves 1400 GW from 2024 to 2023.
The new renewables summary figures have now changed to.
- 2022 – 3200 MW
- 2023 – 2925 MW
- 3024 – 1326 MW
- 2025 – 6576 MW
- 2026 – 1705 MW
- 2027 – 13173 MW
This totals to 28554 MW.
Note.
- The early delivery of the Sofia wind farm has increased the amount of wind farms coming onstream next year, which will help the Winter of 2023/2024.
- It will also help the Liz Truss/Kwasi Kwarteng government at the next election, that should take place in early 2025.
- Hornsea 3 and Hinckley Point C make 2027 a big year for new renewable energy commissioning.
By 2027, we have more than doubled our renewable energy generation.
The Growth Plan 2022
In this document from the Treasury, the following groups of wind farms are listed for acceleration.
- Remaining Round 3 Projects
- Round 4 Projects
- Extension Projects
- Scotwind Projects
- INTOG Projects
- Floating Wind Commercialisation Projects
- Celtic Sea Projects
I will look at each in turn.
Remaining Round 3 Projects
In this group are the the 1200 MW Dogger Bank B and Dogger Bank C wind farms, which are due for commissioning in 2024/25.
Suppose that as with the Sofia wind farm in the same area, they were to be able to be brought forward by a year.
The new renewables summary figures would change to.
- 2022 – 3200 MW
- 2023 – 2925 MW
- 3024 – 3726 MW
- 2025 – 5076 MW
- 2026 – 1705 MW
- 2027 – 13173 MW
This totals to 28554 MW.
It looks like if Dogger Bank B and Dogger Bank C can be accelerated by a year, it has four effects.
- The renewables come onstream at a more constant rate.
- SSE and Equinor, who are developing the Dogger Bank wind farms start to get paid earlier.
- The UK gets more electricity earlier, which helps bridge the gap until Hornsea 3 and Hinckley Point C come onstream in 2027.
- The UK Government gets taxes and lease fees from the Dogger Bank wind farms at an earlier date.
Accelerating the remaining Round 3 projects would appear to be a good idea.
Round 4 Projects
According to Wikipedia’s list of proposed wind farms, there are six Round 4 wind farms, which total up to 7026 MW.
Accelerating these projects, is probably a matter of improved government regulations and pressure, and good project management.
But all time savings in delivering the wind farms benefits everybody all round.
This document from the Department of Business, Industry and Industrial Strategy lists all the Contracts for Difference Allocation Round 4 results for the supply of zero-carbon electricity.
Many of these projects are smaller projects and I suspect quite a few are shovel ready.
But as with the big wind farms, there are some projects that can be brought forward to everybody’s benefit.
Norfolk Boreas
Norfolk Boreas wind farm is one of the Round 4 projects.
The wind farm is shown as 1400 MW on Wikipedia.
On the web site, it now says construction will start in 2023, which could mean a completion by 2025, as these projects seem to take about two years from first construction to commissioning, as I showed in How Long Does It Take To Build An Offshore Wind Farm?.
The new renewables summary figures would change to.
- 2022 – 3200 MW
- 2023 – 2925 MW
- 3024 – 3726 MW
- 2025 – 6476 MW
- 2026 – 1705 MW
- 2027 – 11773 MW
This still totals to 28554 MW.
This acceleration of a large field would be beneficial, as the 2025 figure has increased substantially.
I would suspect that Vattenfall are looking hard to accelerate their Norfolk projects.
Extension Projects
I first talked about extension projects in Offshore Wind Extension Projects 2017.
The target was to add 2.85 GW of offshore wind and in the end seven projects were authorised.
- Sheringham Shoal offshore wind farm – 719 MW with Dudgeon
- Dudgeon offshore wind farm – 719 MW with Sheringham Shoal
- Greater Gabbard offshore wind farm
- Galloper offshore wind farm
- Rampion offshore wind farm – 1200 MW
- Gwynt y Môr offshore wind farm – 1100 MW
- Thanet offshore wind farm – 340 MW
These are the best figures I have and they add up to an interim total of 3359 MW.
I suspect that these projects could be easy to accelerate, as the developers have probably been designing these extensions since 2017.
I think it is reasonable to assume that these seven wind farms will add at least 3000 MW, that can be commissioned by 2027.
The new renewables summary figures would change to.
- 2022 – 3200 MW
- 2023 – 2925 MW
- 3024 – 3726 MW
- 2025 – 6476 MW
- 2026 – 1705 MW
- 2027 – 14773 MW
This now totals to 31554 MW.
Accelerating the extension projects would be a good idea, especially, as they were awarded some years ago, so are probably well into the design phase.
ScotWind Projects
I first talked about ScotWind in ScotWind Offshore Wind Leasing Delivers Major Boost To Scotland’s Net Zero Aspirations.
It was planned to do the following.
- Generate 9.7 GW from six wind farms with fixed foundations.
- Generate 14.6 GW from ten floating wind farms.
But since then three more floating wind farms with a total capacity of 2800 MW have been added, as I wrote about in Three Shetland ScotWind Projects Announced.
I suspect that some of these projects are ripe for acceleration and some may well be generating useful electricity by 2030 or even earlier.
INTOG Projects
I wrote about INTOG in What Is INTOG?.
I can see the INTOG Projects contributing significantly to our fleet of offshore wind turbines.
I have already found a 6 GW/£30 billion project to decarbonise oil and gas rigs around our shores, which is proposed by Cerulean Winds and described on this web page.
If the other large INTOG projects are as good as this one, then we’ll be seeing some sensational engineering.
Floating Wind Commercialisation Projects
This page on the Carbon Trust website is entitled Floating Wind Joint Industry Programme (JIP).
They appear to be very much involved in projects like these.
The page has this description.
The Floating Wind Joint Industry Programme is a world leading collaborative research and development (R&D) initiative dedicated to overcoming technological challenges and advancing commercialisation of floating offshore wind.
This graphic shows the partners and advisors.
Most of the big wind farm builders and turbine and electrical gubbins manufacturers are represented.
Celtic Sea Projects
The Celtic Sea lies between South-East Ireland, Pembrokeshire and the Devon and Cornwall peninsular.
The Crown Estate kicked this off with press release in July 2022, that I wrote about in The Crown Estate Announces Areas Of Search To Support Growth Of Floating Wind In The Celtic Sea.
This map shows the five areas of search.
One Celtic Sea project has already been awarded a Contract for Difference in the Round 4 allocation, which I wrote about in Hexicon Wins UK’s First Ever CfD Auction For Floating Offshore Wind.
Other wind farms have already been proposed for 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.
How do these wind farms fit in with the Crown Estate’s plans for the Celtic Sea?
I certainly, don’t think that the Crown Estate will be short of worthwhile proposals.
Conclusion
More and more wind farms keep rolling in.
What Is INTOG?
This page on the Crown Estate Scotland web site outlines INTOG.
This is the introduction at the top of the page.
Innovation and Targeted Oil & Gas (INTOG) is a leasing round for offshore wind projects that will directly reduce emissions from oil & gas production and boost further innovation.
Developers can apply for seabed rights to build two types of offshore wind project:
IN – Small scale, innovative projects, of less than 100MW
TOG – Projects connected directly to oil and gas infrastructure, to provide electricity and reduce the carbon emissions associated with production
INTOG is designed, in response to demand from government and industry, to help achieve the targets of the North Sea Transition Sector Deal, which is a sector deal between government and the offshore oil and gas industry.
I have a few thoughts and have also found some news stories.
Isolated Communities
This document from the Department of Business, Industry and Industrial Strategy lists all the Contracts for Difference Allocation Round 4 results for the supply of zero-carbon electricity that were announced yesterday.
The document introduces the concept of Remote Island Wind, which I wrote about in The Concept Of Remote Island Wind.
I don’t know of one, but there might be isolated communities, with perhaps a dodgy power supply, who might like to improve this, by means of a small offshore wind farm, meeting perhaps these criteria.
- Less than 100 MW.
- Agreement of the locals.
- A community fund.
- An important use for the electricity.
Locations and applications could be.
- A small fishing port, where winds regularly bring the grid cable down in winter.
- A village with a rail station to perhaps charge battery-electric trains.
- A deep loch, where floating wind turbines are erected.
- To provide hydrogen for transport.
We shall see what ideas are put forward.
Floating Power Stations
Floating wind farms are generally made up of individual turbines on floats.
- Turbines can be up to the largest used onshore or on fixed foundations.
- The Kincardine floating offshore wind farm in Scotland uses 9.5 MW turbines.
- The floats are anchored to the sea bed.
- There is a power cable connecting the turbines appropriately to each other, the shore or an offshore substation.
But we are talking innovation here, so we might see some first-of-a-kind ideas.
Single Floating Turbines
A large floating wind farm, is effectively a large number of floating wind turbines anchored in the same area of sea, and connected to the same floating or fixed substation.
I can’t see any reason, why a single floating wind turbine couldn’t be anchored by itself to provide local power.
It might even be connected to an onshore or subsea energy store, so that it provided a more constant output.
Surely, a single turbine perhaps ten miles offshore wouldn’t be a very large blot on the seascape?
I grew up in Felixstowe and got used to seeing HM Fort Roughs on the horizon from the beach. That is seven miles offshore and some people, I know have windsurfed around it from the beach.
TwinHub
I talked about TwinHub in Hexicon Wins UK’s First Ever CfD Auction For Floating Offshore Wind.
TwinHub mounts two turbines on one float and this is a visualisation of a TwinHub being towed into place.
Note.
- The design turns into the wind automatically, so that the maximum amount of electricity is generated.
- A Contract for Difference for a 32 MW TwinHub has been awarded, at a strike price of £87.30/MWh, that will be installed near Hayle in Cornwall.
- With a capacity factor of 50 %, that will produce just over 140,160 MWh per year or over £12 million per year.
This article on the BBC, which is entitled Funding Secured For Floating Wind Farm Off Cornwall, gives more details of the Hayle TwinHub.
The possibility of a floating wind farm off the coast of Cornwall has moved a step closer after securing government funding, project bosses have said.
Swedish company Hexicon plans to install its TwinHub system, with the hope it could begin operating in 2025.
It would be deployed about 10 miles (16km) off Hayle.
Project supporters said it could be a boost to the local economy and help establish Cornwall in the growing renewable energy sector.
Figures have not been released, but it is understood the government funding has effectively secured a fixed price for the power TwinHub would produce for 15 years, making it economically viable.
The article says that this 32 MW system could develop enough electricity for 45,000 homes.
This could be a very suitable size for many applications.
- As at Hayle, one could be floated just off the coast to power a remote part of the country. As Cornwall has a few old mine shafts, it might even be backed up by a Gravitricity system on shore or another suitable non-lithium battery.
- Could one float alongside an oil or gas platform and be tethered to it, to provide the power?
Scotland’s hydroelectric power stations, prove that not all power stations have to be large to be successful.
Vårgrønn and Flotation Energy’s Joint Bid
This article on offshoreWIND.biz is entitled Vårgrønn And Flotation Energy To Jointly Bid in INTOG Leasing Round, gives a few details about their joint bid.
But there is nothing substantial about ideas and locations.
I can see several joint ventures with a suitable system, bidding for various projects around the Scottish coast.
Cerulean
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.
- It is privately-funded project, that needs no government subsidy and will cost £30 billion.
- It looks like each site will be a hundred turbines.
- If they’re the same, they could be 1.5 GW each.
- 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.

Will There Be An Offshore Wind Supermarket?
I can see the big turbine, float and electrical gubbins manufacturers establishing a one-stop shop for developers, who want to install small wind farms, that meet the INTOG criteria.
So suppose, the archetypal Scottish laird in his castle on his own island wanted a 6 MW turbine to go green, he would just go to the B & Q Offshore web site and order what he needed. It would then be towed into place and connected to his local grid.
I can see modular systems being developed, that fit both local infrastructure and oil and gas platforms.
Conclusion
I can see scores of projects being submitted.
I even know the son of a Scottish laird, whose father owns a castle on an island, who could be taking interest in INTOG. They might also apply under Remote Island Wind in another leasing round.
But we will have to wait until the end of March 2023, to find out who have been successful.
Are The Tories Bluffing About Fracking?
I’ve just listened to a Treasury Minister (Chris Philp (?)) on the BBC and he didn’t mention fracking.
But he did mention more oil and gas in the North Sea, where there is a project agreed between the British and Scottish governments called INTOG, which aims to innovatively cut carbon emissions in the North Sea and possibly extract smaller amounts of gas and oil from existing wells.
As you know, I think fracking is irrelevant. It will take a few years to deliver substantial amounts of gas and we can extract more from the North Sea and by repurposing existing wells.
We might even find one or two existing wells, that could be converted to much-needed gas storage.
I also believe that the cash flow in taxes and leases from offshore wind will be astronomic and it can be used to finance borrowing. We did the same with Artemis to finance the company against future sales. But we were only borrowing millions. We used to parcel up all our leases from companies like Shell, NASA and BP and effectively sell them to Lloyds Bank at a discount.
I’m sure that a clever banker could find a mechanism, that converts future income from offshore wind into a magic money tree for today. Is that what Kwasi Kwarteng has done, in order to cut taxes?
The one problem with offshore wind with the public, is that putting in the cables arouses the NIMBYs. It should also be born in mind, that a lot of the grid connections, go through Tory seats, where NIMBYs are very much against more cables.
So I do wonder, if Moggy has announced the start of fracking to give the NIMBYs a target, so they allow the efficiency of offshore oil and gas to be improved and offshore wind farms to be built without hindrance.
Perhaps Moggy should concentrate on the most important thing that our offshore wind industry needs. This is an innovative pricing mechanism for energy storage, that does the following.
- Allows investors to get a similar return on energy storage to that that they get for offshore wind farms, onshore solar farms and interconnectors.
- Encourages the building of more energy storage.
- Assists in the development of novel energy storage ideas.
As one estimate says we need 600 GWh of energy storage in the UK, sorting this pricing mechanism, can’t come soon enough.
The previous government was talking about this, as I wrote in Ministerial Roundtable Seeks To Unlock Investment In UK Energy Storage.
So continue the conversation, Moggy!
Maximising Space In North Sea Essential To Tackling Energy Security And Net Zero Targets
The title of this post, is the same as that of this article on the Eastern Daily Press.
These two paragraphs introduce the article.
Reviving wells in the Southern North Sea, powering oil and gas platforms with wind turbines, capturing and storing CO2 and hydrogen systems, starting work on world-class offshore wind farms off the coast and consent for Sizewell C nuclear power station – the East of England is ripe with opportunity for companies ready for the challenge.
The industrialised North Sea is becoming supercharged in the name of UK energy security – so much so that a spatial planning exercise is under way to optimise the seabed for energy security and make everything fit for maximum efficiency.
This is an article, that must be read fully.
These are some topics that are discussed.
- Looking at old wells to see if more oil and gas can be extracted.
- Electrification of oil and gas facilities, where economic and possible.
- Powering oil and gas facilities with offshore wind.
This is also said about the Innovation and Targeted Oil and Gas (INTOG) leasing round.
The Innovation and Targeted Oil and Gas (INTOG) leasing round is open for developers to apply for the rights to build offshore wind farms specifically to provide low-carbon electricity to power oil and gas installations in Scotland. It offers the opportunity to enable small scale (less than 100MW) innovation projects, including alternative outputs such as hydrogen.
It looks like mopping up the oil and gas in the North Sea could be promoted as a possible alternative to fracking.
I shall be interested to see how INTOG progresses.
At worst, it will mean that oil and gas installations will be powered by zero-carbon electricity, but in addition it could recover worthwhile amounts of oil and gas.
