Two Thirds Of Sofia Wind Turbines Installed
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Seventy wind turbines have been installed at RWE’s Sofia offshore wind farm in the UK, according to a Notice to Mariners recently issued by the project team.
These two paragraphs give more details of the installation process.
The first of the project’s 100 Siemens Gamesa SG 14-222 DD wind turbines was installed in March 2025, and the work reached the halfway mark in September last year. The vessel deployed for the work is Cadeler’s Wind Peak, which is carrying components for six turbines per trip, operating from the port of Hull.
IWS service operation vessel (SOV) IWS Seawalker is supporting the wind turbine installation work.
Note.
- Sofia is being installed by German Company ; RWE.
- Sofa will use 14 MW Siemens Gamesa wind turbines, some of which have recyclable blades.
- The installation process is being carried out nearly 200 kilometers out to sea on the Dogger Bank.
The power will be connected to the grid at Lackenby substation, which is near the Wilton chemical works, which can certainly you the electricity.
Does Wilton Chemical Works Have A Power Station?
I asked GoogleAI, the question in the title of this section and received this reply.
Yes, the Wilton International industrial site (formerly associated with ICI chemical works) has multiple power stations and significant on-site energy generation, operated primarily by Sembcorp Utilities UK. The site features a biomass power station (Wilton 10), a further biomass unit (Wilton 11), and an energy-from-waste plant, supplying electricity and steam to chemical and industrial businesses on-site.
Note.
- Wilton 10 opened as a biomass power station in 2002.
- Wilton 11 opened as a biomass power station in 2016.
I seem to remember, that one of these power stations was there on my visits to Wilton for ICI in the 1970s.
Key details regarding power generation at Wilton:
Biomass & Waste-to-Energy:
The site transitioned from coal-fired units to renewable biomass and waste-to-energy, utilizing wood and other byproducts for power and heat generation.
Sembcorp Utilities:
Sembcorp operates the site’s energy infrastructure, which includes five different generation assets and a private wire network.
Capacity: The site hosts significant generation capacity, including a 52MW biomass unit and a 35MW unit.
Future Projects: The site is involved in developments for net-zero emissions, including the Whitetail Clean Energy project, which is planned as the UK’s first Net Zero emissions power plant with Carbon Capture and Storage (CCS).
The site serves as a “plug and play” industrial location offering on-site, cost-effective energy.
Conclusion
This would appear to be a sensible small power system providing 1400 GW of wind power, backed up if needed be by the two biomass units, which total 87 MW.
Note, that ICI were storing gases under the site for many years, so I suspect, that Carbon Capture and Storage, might work well at this location.
I can see other places, where a wind farm, is combined with energy from waste for backup.
Are Wind Farms Being Backed Up By Energy From Waste Units In The UK?
I asked GoogleAI, the question in the title of this section and received this reply.
Yes, but only in a limited, complementary capacity, rather than as a direct, large-scale substitute for wind power.
Energy from Waste (EfW) units—commonly known as incinerators—are increasing in the UK, but their role in the grid is different from how we “back up” wind.
Here is a breakdown of how it works:
1. The Role of EfW (Baseload, not Backup)
Baseload Generation: EfW plants run 24/7 to burn waste. They provide a steady, consistent, predictable “baseload” of electricity (about 2–3% of UK supply).
Intermittency: Because they run constantly, they cannot ramp up and down quickly when the wind stops blowing. Therefore, they are not a “flexible” backup in the same way gas power plants are.
Partial Renewable: Around 50% of the energy produced by EfW is considered renewable (organic waste), helping the UK hit green targets.
2. What Actually Backs Up Wind?
When wind farms stop producing power during low-wind periods (often called “dunkelflaute”), the UK relies on other sources:
Natural Gas Plants: These are the primary, flexible backup that can ramp up instantly to fill gaps in renewable production.
Interconnectors: Imported electricity from other countries (e.g., Norway, France).
Battery Storage: Growing, but still small-scale compared to total demand.
3. How EfW Helps the Grid
EfW does assist the grid by providing system inertia and consistent, low-carbon, on-demand energy, reducing the need for more fossil fuels to be burnt at certain times. They are particularly useful for providing power when the grid is congested, but they do not specifically act as a “spare tire” for wind farms.
4. Future Trends
The government is looking to attach Carbon Capture and Storage (CCS) to EfW units, which would make them a low-carbon, dependable, and sustainable part of the energy mix by the 2030s.
In summary: EfW plays a part in supporting a greener grid, but it is not a direct substitute for the flexibility required to back up intermittent wind power.
5. Hydrogen Power
This is a section, that artificial intelligence has unsurprisingly left out, as no country has yet built the hydrogen storage and the power stations to generate the electricity, when it is needed.
But Note.
- SSE are building a big hydrogen store in Yorkshire at Aldbrough.
- Centrica are converting the Rough gas storage to a hydrogen store.
- SSE are building a 910 MW hydrogen-powered power station at Keadby.
- SSE are building a 1200 MW hydrogen-powered power station at Ferrybridge.
I suspect if you were building a chemical plant and Wilton fitted your budget, you would take a look.
National Grid, TenneT Germany Launch GriffinLink, A First Of A Find Project To Maximise Offshore Wind
The title of this post is the sane as that of this press release from National Grid.
These three bullet points serve as sub headings.
-
National Grid and TenneT Germany announce our cooperation on GriffinLink, a planned GB-Germany multi-purpose interconnector (MPI).
-
GriffinLink would support energy security, accelerate the connection of offshore wind and mark a coordinated approach on supply chains and infrastructure.
-
Announced at the North Sea Summit in Hamburg, the project could maximise shared offshore wind resources in the most efficient way.
These two paragraphs add more detail.
National Grid will partner with TenneT Germany to develop GriffinLink, a new multi-purpose interconnector (MPI) project, which could connect British and German offshore wind to both countries. It marks a step towards a more integrated, flexible, and efficient energy system for both Great Britain and Germany which delivers secure, affordable energy for consumers.
GriffinLink could make an important contribution to security of supply and market integration in northwestern Europe. Cross-border hybrid energy systems such as GriffinLink make it possible to feed cleaner electricity into the grid where it can be generated and transport it exactly where it is needed.
Note this integrated approach means.
- Better utilisation of the grids and is a more efficient use of renewable energy across national borders;
- Lowering the costs involved, and the supply chain materials required and;
- A reduced impact on coastal communities and the environment.
As a ‘multi-purpose’ interconnector connecting wind in two countries, GriffinLink would be the first project of its kind in Europe and a milestone for cross-border energy security and stability.
It will also connect the UK’s offshore wind power to someone someone who needs it and will pay good money for it.
I asked Google AI, “How much energy we will be exporting to Europe in 2030” and received this reply.
By 2030, the UK is expected to be exporting significant amounts of electricity to Germany, largely enabled by the NeuConnect interconnector, which is set to become operational around 2028 and will have a capacity of 1.4 GW. While precise, definitive figures for 2030 are subject to market conditions, key data suggests:
NeuConnect Capacity: The 725km subsea link between Kent (UK) and Wilhelmshaven (Germany) will allow 1.4 GW of electricity to flow in either direction.
Net Export Position: The UK is positioned to become a net exporter of electricity to Europe by the 2030s, fueled by a massive expansion in offshore wind capacity, aiming for up to 50GW by 2030.
Grid Interconnection: By 2030, the UK’s total interconnection capacity to Europe is planned to increase to 18GW, up from 8GW.
Hydrogen Focus: In addition to electricity, the UK is exploring the potential to export up to 35 TWh of hydrogen to Germany by 2030.
That will do nicely!
Cummins To Cease New Electrolyser Activity Amid Worsening Market
The title of this post, is the same as that of this article on Renewables Now.
These are the first three paragraphs.
Cummins Inc has decided to stop new commercial activity in the electrolysers space following a strategic review of the segment launched last year, citing deteriorating market conditions and weakening customer demand.
The decision is linked to USD 458 million (EUR 388.4m) of charges for the full-year 2025 related to the electrolyser business within the company’s zero-emission technologies arm, Accelera, of which USD 415 million were non-cash charges.
The company noted that it will continue to fulfil existing customer commitments before winding down new commercial activity in the segment.
Although, I am in favour of using hydrogen as a fuel, I recognise, that traditional electrolysis is not the most efficient process.
These methods are more efficient.
HiiROC
- HiiROC use a process, that they call Thermal Plasma Electrolysis to split any hydrocarbon gas into hydrogen and carbon black.
- HiiROC originated in the University of Hull.
- Typical gases that can be used are chemical plant off-gas, biomethane and methane.
- I like the ability to use chemical plant off-gas, as some of this is particularly nasty and HiiROC may offer safe disposal.
But the big advantage is that the HiiROC process is five times more energy efficient than traditional electrolysis.
The carbon black is no useless by-product, but has several valuable uses in its own right, which are detailed in its Wikipedia entry.
These two paragraphs from Wikipedia, give a summary of the more common uses of carbon black.
The most common use (70%) of carbon black is as a reinforcing phase in automobile tires. Carbon black also helps conduct heat away from the tread and belt area of the tire, reducing thermal damage and increasing tire life. Its low cost makes it a common addition to cathodes and anodes and is considered a safe replacement to lithium metal in lithium-ion batteries. About 20% of world production goes into belts, hoses, and other non-tire rubber goods. The remaining 10% use of carbon black comes from pigment in inks, coatings, and plastics, as well as being used as a conductive additive in lithium-ion batteries.
Carbon black is added to polypropylene because it absorbs ultraviolet radiation, which otherwise causes the material to degrade. Carbon black particles are also employed in some radar absorbent materials, in photocopier and laser printer toner, and in other inks and paints. The high tinting strength and stability of carbon black has also provided use in coloring of resins and films. Carbon black has been used in various applications for electronics. A good conductor of electricity, carbon black is used as a filler mixed in plastics, elastomer, films, adhesives, and paints. It is used as an antistatic additive agent in automobile fuel caps and pipes.
It can also be used as a soil improver in agriculture.
HiiROC would appear to be five times more energy efficient than traditional electrolysis.
I would also rate the range of their investors as a particular strength.
Google AI lists these companies as investors.
HiiROC, a UK-based developer of plasma torch technology for “turquoise” hydrogen production, is backed by a consortium of industrial and strategic investors. Key investors include Centrica, Melrose Industries, Hyundai Motor Company, Kia, HydrogenOne Capital, CEMEX Ventures, Wintershall Dea, and VNG.
Note.
- CEMEX must be going to decarbonise cement making.
- Melrose describe themselves as an industry-leading aerospace technology provider.
- Will we be seeing hydrogen cars from Korean manufacturers?
- Wintershall Dea is Europe’s leading independent gas and oil company.
HiiROC has an impressive list of investors.
Bloom Energy
I wrote about Bloom Energy’s process in Westinghouse And Bloom Energy To Team Up For Pink Hydrogen.
This method also looks promising.
- Westinghouse Electric Company is an American builder of nuclear power stations.
- Bloom Energy Corporation make a solid-oxide electrolyser.
- Pink hydrogen is green hydrogen produced using nuclear power.
It uses electrolysis at a higher temperature, which speeds it up.
Desert Bloom
This is an Australian process, that I wrote about in 10GW Green Hydrogen Project Aims To Electrolyze Water Drawn From Desert Air.
Conclusion
You can understand, why Cummins are getting jumpy!
But you have to remember that when I worked in a hydrogen plant in the 1960s, the hydrogen was an unwanted by-product and it was mixed with coal gas and sent down the power station to raise steam, so that it could be used to do something useful.
FEV And Daimler Buses Create Hydrogen Coach Demonstrator
The title of this post is the same as that of this article on Automotive World.
This is the sub-heading.
Daimler Buses and engineering firm FEV have developed a hydrogen fuel cell-powered Setra coach, marking the first hydrogen demonstrator vehicle in the coach segment for the Daimler Truck subsidiary. The H₂ Coach technology demonstrator, which was handed over to Daimler Buses in summer 2025 following approximately two years of development and approval by German technical inspection authority TÜV, offers a range of at least 800 kilometres per tank filling and is intended for testing purposes.
The article also has a picture, which shows.
- A typical modern coach design with three axles.
- Setra H2 Coach branding.
- A Slogan of “Travelling Towards a Sustainable Future”
It looks very similar to images of Wrightbus’s three-axle Contour design. But that would mean, they could fit similar infrastructure.
But when I asked Google AI, when the Wrightbus three-axle hydrogen coach would enter passenger service, I received this answer.
Wrightbus’s three-axle hydrogen fuel cell electric coach is planned for launch in 2026. The company, which is developing the vehicle in Ballymena, Northern Ireland, has confirmed the project is aimed at decarbonising long-distance travel, with a projected range of up to 1,000 km.
It would appear that Wrightbus are ahead on range and timescale.
University Of Alberta Partners With City of Edmonton And Diesel Tech Industries To Pilot Hydrogen-Diesel Bus Retrofits
The title of this post, is the same as that of this article on Pulse 2.0.
These two paragraphs introduce what is a comprehensive practical approach to decarbonising a fleet of diesel buses.
The University of Alberta is partnering with the City of Edmonton and Diesel Tech Industries to cut carbon emissions from Edmonton’s fleet of diesel-powered buses by integrating hydrogen fuel into existing combustion engines.
The initiative focuses on developing a practical retrofit approach to help transit agencies and other vehicle operators reduce emissions quickly without waiting for full fleet replacement. Project leaders say that if the pilot succeeds, the work could translate into a deployable solution for operators across Canada seeking near-term carbon reductions while maintaining current diesel assets.
Note.
- The City of Edmonton has around a thousand buses.
- Many of Edmonton’s buses have Cummins engines.
- Cummins are decarbonising the company and have developed hydrogen-conversions for some of their diesel engines.
- I am sure that this technique could be used to convert London’s thousand new Routemaster buses, with their Cummins engines.
This project seems to have a lot of possibilities to get very much larger.
‘Mobilising EUR 1 Trillion in Investments’ | North Sea Countries, Industry, TSOs to Ink Offshore Wind Pact
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Government officials from Belgium, Denmark, France, Germany, Ireland, Luxembourg, the Netherlands, Norway and the UK are set to sign a declaration confirming the ambition to build 300 GW of offshore wind in the North Seas by 2050, and an investment pact with the offshore wind industry and transmission system operators (TSOs) that is said to mobilise EUR 1 trillion in economic activity.
These three paragraphs add a lot of powerful detail.
Under the Offshore Wind Investment Pact for the North Seas, to be signed today (26 January) at the North Sea Summit in Hamburg, governments of the nine North Sea countries will commit to building 15 GW of offshore wind per year from 2031 to 2040.
The heads of state and energy ministers will also vow to de-risk offshore wind investments through a commitment to provide two-sided Contracts for Difference (CfDs) as the standard for offshore wind auction design. The pact also commits governments to remove any regulatory obstacles to power purchase agreements (PPAs), according to WindEurope, which will sign the pact on behalf of the industry.
On the industry’s side, the commitment is to drive down the costs of offshore wind by 30 per cent towards 2040, mobilise EUR 1 trillion of economic activity for Europe, create 91,000 additional jobs and invest EUR 9.5 billion in manufacturing, port infrastructure and vessels.
These two paragraphs say something about cost reductions.
The cost reduction of offshore wind is planned to be achieved through scale effects, lower costs of capital and further industrialisation supported by clarity and visibility on the project pipeline.
The transmission system operators (TSOs) will identify cost-effective cooperation projects in the North Sea, including 20 GW of promising cross-border projects by 2027 for deployment in the 2030s.
I hope there is a project management system, that can step into this frenzy, just as Artemis did in the 1970s with North Sea Oil and Gas.
The BBC has reported the story under a title of UK To Join Major Wind Farm Project With Nine European Countries.
this is the sub-title.
The UK is set to back a vast new fleet of offshore wind projects in the North Sea alongside nine other European countries including Norway, Germany and the Netherlands.
These six paragraphs add more detail.
The government says the deal will strengthen energy security by offering an escape from what it calls the “fossil fuel rollercoaster”.
For the first time, some of the new wind farms will be linked to multiple countries through undersea cables known as interconnectors, which supporters say should lower prices across the region.
But it could prove controversial as wind farm operators would be able to shop around between countries to sell power to the highest bidder – potentially driving up electricity prices when supply is tight.
Energy Secretary Ed Miliband will sign a declaration on Monday at a meeting on the future of the North Sea in the German city of Hamburg, committing to complete the scheme by 2050.
Jane Cooper, deputy CEO of industry body RenewableUK, said the deal would “drive down costs for billpayers” as well as increasing “the energy security of the UK and the whole of the North Sea region significantly”.
But Claire Countinho, shadow energy secretary, warned “we cannot escape the fact that the rush to build wind farms at breakneck speed is pushing up everybody’s energy bills.”
Claire Coutinho, as an outsider at present and a member of a party out of Government had to say something negative, but her negotiations when she was UK Energy Minister with her German opposite number, which I wrote about in UK And Germany Boost Offshore Renewables Ties, seem very much a precursor to today’s agreement.
Legal Challenge Against Gatwick Airport’s Second Runway To Begin
The title of this post is the same as that of this article on ITVX.
These four paragraphs add more details.
Plans to challenge a second runway at Gatwick Airport will be heard in the High Court next week.
The campaign and environmental group Communities Against Gatwick Noise Emissions (CAGNE) opposes Transport Secretary Heidi Alexander’s decision to grant development consent for the project.
In the hearing, which will run from 20 to 23 January 2026, CAGNE’s argues that the climate change impacts of the extra runway have not been properly assessed.
The planned expansion would see the repurposing of Gatwick Airport’s emergency runway for use as a second operational runway. The extra capacity is expected to lead to more than 100,000 more flights per year.
These two paragraphs give CAGNE’s case.
CAGNE says that this decision was flawed, arguing that there are numerous gaps in the environmental assessment of the airport expansion. These include a failure to adequately assess inbound flight emissions, the climate impact of non-carbon dioxide emissions, the handling of additional sewage, and noise pollution.
The group also argues that the second runway plans rely too heavily on the UK’s Jet Zero Strategy (JZS), which assumes ambitious improvements in the aviation industry in areas such as fuel efficiency.
My feelings are as follows.
- We need more runway capacity.
- Eventually all aircraft will be powered by electricity, hydrogen or sustainable aviation fuel (SAF).
- Because of the need for large amounts of renewable electricity to make hydrogen and SAF, the runway will need to be near offshore wind farms.
Only Doncaster Sheffield, Gatwick, Liverpool, Stansted and some Scottish airports are near the sea or could be connected to the coast by an easy-to-build cable or pipeline.
CAGNE may well win their case, but I fell Nimbys will also stop Heathrow getting a third runway.
Development Consent Decision On 3 GW Dogger Bank South Project Postponed
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The UK Secretary of State for Energy Security and Net Zero has set a new deadline for the decision on the Development Consent Order (DCO) for Dogger Bank South, a 3 GW offshore wind project developed by RWE, which the company owns in partnership with Masdar.
These two paragraphs add more detail to the project.
The statutory deadline for the decision on the project was 10 January 2026. This has now been moved to 30 April.
According to a statement from the Minister for Energy Consumers, Martin McCluskey, the extension will allow time to request further information that was not provided for consideration during the examination period and to give all interested parties the opportunity to review and comment on such information.
I clipped this map from the Dogger Bank South web site.
Note.
- Bridlington, Kingston-Upon-Hull and Scarborough can be picked out on the coast of East Yorkshire.
- The two wind farms and the route of the cables to the shore can be clearly seen.
I just wonder, whether the nature of the project is changing.
Consider.
- Three GW is a lot of power to move across Yorkshire to where it can be connected to the grid.
- In Consultation On Offshore Wind Reform: Hydrogen Sector Calls For Hybrid Connection Concepts And Warns Of Compensation Risks, German companies involved in the AquaVentus project are calling for more hydrogen to be produced offshore and piped to the shore.
- Could hydrogen produced in the Dogger Bank Wind farms be piped to the Northern end of the AquaVentus pipeline on the German sector of the Dogger Bank?
- A pipeline or cable could still bring energy to Yorkshire.
- The hydrogen could go to the hydrogen stores at Aldbrough and Rough.
- SSE and Centrica could play hydrogen-bankers to the Germans, as Germany is short of hydrogen storage.
- East Yorkshire is building two hydrogen power stations at Keadby and Ferrybridge.
- Support for the Dogger Bank South wind farms will probably be from RWE’S Grimsby hub.
Is this the Anglo-German co-operation, I talked about in UK And Germany Boost Offshore Renewables Ties at work?
I can see benefits for this arrangement for the UK.
- Hydrogen production is offshore.
- A lot of the onshore employment is in the UK.
- There will be a hydrogen pipeline between Germany and the vast hydrogen storage of Humberside via the German Dogger Bank and Dogger Bank South wind farms.
- Will there be a hydrogen pipeline between the North of Scotland and Humberside via the AquaVentus pipeline?
- There will also be a substantial cash flow to the UK Treasury because of all the hydrogen production in UK waters.
RWE may also be able to use a standard hydrogen production platform in German and UK waters.
This is the sort of plan, that the money men will like.
Direct London Trains ‘Could Start In 2026’
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A new train company is hoping its proposals for new daily services from Shropshire to London Euston could begin towards the end of 2026.
Wrexham, Shropshire and Midlands Railway (WSMR), which is led by international rail firm Alstom, submitted a new bid at the end of last year to provide four daily trains.
These two paragraphs add detail to the story.
The county has not had a direct train link to the capital since Avanti West Coast stopped its single daily service in 2024 because of low passenger numbers.
The move has been welcomed by regular commuter Charlotte Foster, who lives on the Welsh border. She said a direct service would save her the stress of missing a connection or catching a train elsewhere.
These are my thoughts on this proposal.
I wonder If Alstom Will Be Using This route To Trial Hydrogen-Powered Trains?
Consider.
- The route was a failure for Virgin Trains.
- Perhaps the curiosity value of hydrogen-trains will generate sufficient traffic.
- Hydrogen-electric trains will be very quiet. Those in Germany are hydrogen-electro-mechanical and very noisy.
- The trains will be based on the proven Aventra platform.
- I reported on Alstom’s hydrogen trains for the UK in Alstom Plans To Operate Its Own Passenger Train Service In The UK For The First Time.
- Perhaps Alstom feel that an extended test will convince passengers that the trains are a good idea.
- An extended test would give proper costings for Great British Railways and prospective open access operators.
The map downloaded from the BBC article shows the route.
Note.
- There are eight intermediate stops.
- Euston and Wolverhampton is 124.9 miles and fully electrified.
- Wolverhampton and Wrexham General is 59.9 miles and is not electrified.
- The section of the route without electrification at 120 miles return might need some new electrification for battery-electric trains, but from their experience in Germany, I suspect that Alstom, will know how to cover the route using hydrogen-hybrid trains, which would use the existing electrification between Euston and Wolverhampton.
This picture shows a visualisation of a possible Alston hydrogen train, which would probably be built in Derby on an Aventra platform.
Note.
- It could be up to five-cars long.
- I suspect Alstom could give the train a 125 mph cruising speed, so it could mix it with all the express trains between Euston and Wolverhampton.
- The trains would have a very long range on hydrogen.
- Hydrogen trains could certainly handle a round trip between Wolverhampton and Holyhead on a single fuelling.
- Hydrogen fuelling is likely to be setup at Cemex at Wrexham and the Port of Holyhead.
I think it could be an ideal trial route for hydrogen trains.
But also it could bring growth to the towns and cities between Wolverhampton and Holyhead.
Would Alstom’s Hydrogen-Hybrid Trains Be Suitable For Other Routes?
Most Certainly!
In the first place, the route could be extended to Holyhead, which would surely bring growth to the towns and cities between Wolverhampton and Holyhead.
This would create a zero-carbon route between London and the Island of Ireland.
But around the UK, there would be other routes.
I can envisage these routes being run by hydrogen-hybrid trains.
- London Waterloo and Exeter – Third-rail operation
- London Bridge and Uckfield – Third-rail operation
- London Bridge and Hoo – Third-rail operation
- East Coastway and Marshlink Lines – Third-rail operation
- Scotland – Replacement of Inter7City trains and filling in the gaps in electrification.
Note.
- Some areas already have or have plans for hydrogen supply networks.
- With the exception of supplying hydrogen, very little infrastructure would be needed.
- Hydrogen trains should be fairly quiet.
- Hydrogen trains don’t create much disruption, when they are installed.
Aventras have been fairly well received and can be between three and nine cars.
