Nuclear Plan For Decommissioned Coal Power Station

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

This is the sub-heading.

Nuclear power could be generated on the site of a former coal power station in Nottinghamshire.

These first four paragraphs add details.

Cottam Power Station was decommissioned in 2019, and in August its eight 114m (375ft) cooling towers were demolished.

Three businesses – American energy firm Holtec International, EDF UK, and real estate manager Tritax – have now signed an agreement to set up a small modular reactor (SMR) to power “advanced” data centres at the 900-acre site.

Holtec said the project could create “thousands of high-skilled manufacturing and construction jobs”, as well as “long-term roles”.

The SMR at Cottam would be the second of its kind, following the creation of a plant at Palisades in Michigan, in the US.

Note.

  1. Cottam was a 2,000 MW power station, that could run on coal, oil and biomass.
  2. If a nuclear power station is built at Cottam, it will be one of the first nuclear stations not close to the coast.

I asked Google AI for details of the plant at Palisades in Michigan and received this reply.

The Palisades SMR project at the Palisades Nuclear Plant in Michigan will feature two Holtec SMR-300 units, each producing at least 300 megawatts of power, for a combined total of at least 600-640 megawatts of net power. This project aims to have the first US dual-unit SMR 300 system operational by 2030, and the SMRs are designed to produce electricity and provide steam for other industrial purposes.

It does appear that the new generation of reactors from Holtec, Rolls-Royce and X-energy are smaller than many nuclear reactors built in the last twenty years.

This Google Map shows the Cottam site.

Note.

  1. The River Trent surrounds the site.
  2. Could the Trent be used for cooling water?
  3. The cooling towers are still in place, so the image must have been taken before August.
  4. The sub-station is in the South-West corner of the site.
  5. The railway over Torksey viaduct is disused.

It would appear that there is generous space for the SMRs and a few data centres.

The Cottam Solar Project

In DCO Decision On 480MW West Burton Solar NSIP Delayed Until 2025, I wrote about three large solar projects in Eastern England.

The Cottam Solar Project was one of the projects and wants to use the Cottam site.

  1. The Cottam Solar Project has a web site.
  2. It will have a capacity of 600 MW, with a battery, with a battery with a 600 MW output and a 600 MWh capacity.
  3. The solar farm will use the grid connection of the former coal-powered Cottam power station.
  4. The project is massive and will cover 1270 hectares.

Will this solar project lease space for the SMR, so they can co-exist?

Conclusion

It does appear that there are more than one use for old coal-fired power station sites.

  • 2029 – Norfolk Vanguard West – 1,380 MW
  • 2029 – North Falls – 504 MW
  • 2029 – West of Orkney – 2,000 MW
  • 2030 – Awel y Môr – 500 MW
  • 2030 – Bellrock – 1,200 MW
  • 2030 – Berwick Bank – 4,100 MW
  • 2030 – Caledonia – 2,000 MW

  • 2030 – Five Estuaries – 353 MW
  • 2030 – Morven – 2,907 MW
  • 2030 – N3 Project – 495 MW
  • 2030 – Outer Dowsing – 1,500 MW
  • 2030 – Rampion 2 Extension – 1,200 MW

This gives these yearly totals, if I use pessimistic dates.

  • 2025 – 1,235 MW
  • 2026 – 4,807 MW
  • 2027 – 5,350 MW
  • 2028 – 4,998 MW
  • 2029 – 9,631 MW
  • 2030 – 15,263 MW

This adds up to a total of 58,897 MW.

Solar Power

For solar power, I just asked Google AI and received this answer.

The UK government aims to have between 45 and 47 gigawatts (GW) of solar power capacity by 2030. This goal is set out in the Solar Roadmap and aims to reduce energy bills and support the UK’s clean power objectives. The roadmap includes measures like installing solar on new homes and buildings, exploring solar carports, and improving access to rooftop solar for renters.

Let’s assume that we only achieve the lowest value of 45 GW.

But that will still give us at least 100 GW of renewable zero-carbon power.

Energy Storage

For pumped storage hydro, I asked Google AI and received this answer.

The UK’s pumped storage hydro (PSH) capacity is projected to more than double by 2030, with six projects in Scotland, including Coire Glas and Cruachan 2, potentially increasing capacity to around 7.7 GW from the current approximately 3 GW. This would be a significant step towards meeting the National Grid’s required 13 GW of new energy storage by 2030, though achieving this depends on policy support and investment.

It looks like there is about another 5 GW of capacity to find.

Global Offshore Wind Capacity Reaches 83 GW, 100 GW More To Be Awarded in 2025-2026, New Report Says

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

This is the sub-heading.

According to a new market report from the Global Wind Energy Council (GWEC), there are now 83 GW of offshore wind capacity installed globally, with 48 GW more in the construction phase worldwide as of May this year.

The first paragraph is a quote from Rebecca Williams, Deputy CEO at GWEC.

Our report finds that there is now already 83 GW of offshore wind installed worldwide, keeping the lights on for 73 million households, and powering countries’ economic development. There is currently a further 48 GW of offshore wind [under] construction worldwide. With its unique position in the marine space, and ability to produce large amounts of reliable, homegrown power, nations around the world are pushing forward the technology to enhance their energy independence and autonomy

I doubt Ms. Williams will be on the Donald Trump’s Christmas card list.

The article is worth a full read, as it contains some interesting statistics.

This is the last paragraph of the article.

Global Wind Energy Council’s 2024 global offshore wind outlook for total additions in the 2025-2029 period was 156.72 GW, which has now been downgraded to 118.56 GW.

These are my estimates for the amount of offshore wind in the UK.

  • Currently Installed – 16, 035 MW
  • To Be Installed in 2025 – 1,235 MW
  • To Be Installed in 2026 – 4,907 MW
  • To Be Installed in 2027 – 5,750 MW
  • To Be Installed in 2028 – 480 MW
  • To Be Installed in 2029 – 1,363 MW

The UK should be installing 13,735 MW, which would.

  • Lift total offshore wind capacity to 29.8 GW.
  • This is an 86 % increase in capacity from July 2025.
  • As I write this, we are using 29.3 GW.
  • We would be adding 11.6 % of the global additions for 2025-2029, which isn’t bad for such a small country.

All this wind will need to be backed up, for when the wind doesn’t blow.

So I asked Google AI how much electricity storage we will have by 2029 and got this AI Overview.

In 2029, the UK is expected to have a significant amount of battery energy storage capacity, with estimates ranging from 27 to 29 GW, according to the House of Commons Library and Cornwall Insight. This capacity is crucial for supporting the UK’s transition to a clean energy system and ensuring a stable electricity supply.

Obviously, Google AI isn’t that intelligent, as it made the mistake made by many electricity storage companies of just giving the output of the battery, as it sounds better, rather than both  the output and the storage capacity.

Consider.

  • Most Battery Energy Storage Systems (BESS) can provide two hours of output.
  • Highview Power’s big batteries are 200 MW/2.5 GWh, so will provide 12.5 hours of output.

If I assume that the average storage is just two hours, that means the available storage will be at least 54 GWh.

Given that we also had 16 GW of solar power in June 2024 and if this increases at a similar rate to offshore wind power, it will certainly be able to help fill the energy storage, I think we’ll have enough renewable energy to play a big part in the next election.

About The Global Wind Energy Council (GWEC)

I asked Google AI for a summary about GWEC and got this AI Overview.

The Global Wind Energy Council (GWEC) has its global headquarters in Lisbon, Portugal. Additionally, they have offices in Brussels, Belgium; Singapore; and London, UK.

GWEC’s presence is not limited to these locations, as they have a global network of experts working across different continents, according to the organization’s website. Their flagship report, the Global Wind Report, is launched annually in London. For example, the 2025 report launch took place in London.

Unsurprisingly, it doesn’t mention an office in the United States.

The report, which forms the basis of this post, can be downloaded from the GWEC web site.

Reform Declares War On County’s Net-Zero Projects

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

This is the sub-heading.

Reform UK leaders in Lincolnshire say they have “declared war” on green energy projects.

These three paragraphs outline their policies.

Boston and Skegness MP Richard Tice, Greater Lincolnshire’s mayor Dame Andrea Jenkyns and Councillor Sean Matthews, who leads the county council, launched a campaign at a press conference held in Boston earlier.

They said they opposed wind and solar farms and battery storage facilities, with Tice adding: “It is an absolute outrage what the madness of net stupid zero is doing to our county, as well as to our country.”

The government said green energy was vital in delivering energy security, while Labour MP Melanie Onn argued Reform’s stance posed a risk to thousands of jobs.

It should be noted that Lincolnshire has a lot of projects, that will be concerned with renewable energy.

Lincolnshire is one of the UK counties, with the highest level of wind power.

  • There are over 7 GW of wind farms, that already do or will land their electricity in the county including 5.5 GW from the world’s largest offshore wind farm; Hornsea.
  • There is approaching 300 MW of onshore wind in the county, which includes England’s largest onshore wind farm at Keadby, which is 68 MW.

I asked Google how much solar there was in the county and I got this AI Overview.

Lincolnshire has a significant amount of solar power capacity, with several large solar farms and numerous smaller installations. The county is a major location for solar energy development, with some projects aiming to power tens or even hundreds of thousands of homes.

In the real world of wind and solar energy, all of this renewable energy will need backup and the county has it in hundreds of megawatts.

  • Keadby One is a 732 MW gas-fired power station owned by SSE Thermal.
  • Keadby Two is a 849 MW gas-fired power station owned by SSE Thermal.
  • Keadby Three will be a 910 gas-fired power station, fitted with carbon capture, that is being developed by SSE Thermal.
  • Keadby Next Generation Power Station is a 1800 MW hydrogen-powered power station, that is being developed by Equinor and SSE Thermal. I wrote about it in Consultation On Plans For Keadby Hydrogen Power Station To Begin and it will generate 900 MW of zero-carbon electricity.

Now that it what I call backup.

Conclusion

Lincolnshire generates a lot of renewable energy and Reform UK want to throw it all away.

As I showed in US Gov’t Withdraws All Offshore Wind Energy Areas, Trump’s policies against renewable energy and wind in particular are not good for investment and employment.

We don’t want Trump’s policies in the UK.

And especially in Lincolnshire, where all this energy can attract jobs.

Nigel Farage Speech: Persistent Offenders Would Face Life Sentences

The title of this post, is the same as that of this article in The Times.

This is the sub-heading.

The Reform UK leader pledged more prison spaces, deportation of criminals and zero-tolerance policing as part of a six-week Lawless Britain campaign drive.

These three paragraphs give more detail about what criminals can expect and how much it will cost.

Every shoplifter would be prosecuted and stop and search powers used to “saturation point” under Nigel Farage’s pledge to make Reform UK the “toughest party on law and order this country has ever seen”.

He said that a Reform government would crack down on prolific offending by imposing life sentences on those who commit three or more offences.

The Reform leader set out plans to spend £17.4 billion to cut crime by half in the first five years if the party wins the next general election — an annual cost of £3.5 billion.

At least hanging and flogging aren’t mentioned. But he does suggest sending one of our worst child murderers to El Salvador and that Britain would leave the European Convention on Human Rights.

This paragraph says how he will pay for this law and order policy.

Farage said Reform would pay for the £17.4 billion law and order crackdown by ditching HS2 and net zero policies — money which has also been pledged for other policies.

I have just done a little calculation about how much offshore wind power should be commissioned by January 2029, which will likely be before the expected 2029 General Election.

  • In October 2023, there was 15,581 MW of operational offshore wind.
  • Currently there are 10,842 MW under construction, that should be commissioned by January 2029.
  • There is also 2,860 MW of smaller wind farms, which have yet to be started that should be commissioned by January 2029.
  • That all totals up to 29, 285 MW or 29.3 GW.
  • Another 12 GW of offshore wind is scheduled to be commissioned in 2029 and 2030.

Currently, as I write this we are generating 29.3 GW from all sources.

I asked Google AI how much solar energy we will have in January 2029 and got this answer.

In January 2029, the UK is projected to have a significant amount of solar energy capacity, with the government aiming for 45-47 GW of total solar power by 2030.

Let’s assume the sun only shine half the time and say 20 GW on average.

 

We’ll also have 4.4 GW from Hinckley Point C and Sizewell B, as all other nuclear will have been switched off.

I asked Google AI how much energy storage we’ll have by January 2029 and got this answer.

In January 2029, the UK is projected to have around 120 GWh of battery energy storage capacity, according to a European report. This is part of a broader goal to reach 400 GWh by 2029 for the EU-27, with the UK contributing significantly to this total.

If there’s say another Great Storm, the dozens of interconnectors between the UK and Europe should keep us all going.

It looks to me that by January 2029, we’ll be substantially on the way to being powered by renewables.

Most of the net zero money will have been spent and we’ll be almost at net zero.

Phase One of High Speed Two has a target date of 2030, and I suspect that the engineers working on the project will get trains running between Old Oak Common and Birmingham Curzon Street stations before the General Election, just because if NF’s going to cancel the project, they might as well do their best to get him to lose the election.

So at best he might get a year’s savings from stopping High Speed Two, but an unfinished High Speed Two, will be a joke on NF and make him look a complete laughing stock!

Rolls-Royce And Duisport Launch CO2-Neutral, Self-Sufficient Energy System For New Port Terminal

The title of this port is the same as that of this press release from Rolls-Royce.

These two bullet points act as sub-headings.

  • First mtu hydrogen CHP units, battery storage systems and fuel cell systems from Rolls-Royce in operation.
  • Benchmark for sustainable energy supply in logistics centers worldwide.

These three paragraphs give more details of the project.

Rolls-Royce and Duisburger Hafen AG have opened a CO2-neutral and self-sufficient energy system for the new Duisburg Gateway Terminal, located in the Rhine-Ruhr industrial region of Germany. The core components are two mtu combined heat and power units designed for operation with 100 percent hydrogen, which are being used here for the first time worldwide. The system is supplemented by an mtu battery storage system, mtu fuel cell systems and a photovoltaic system integrated via an intelligent energy management system.

The Enerport II flagship project, funded by the German Federal Ministry for Economic Affairs and Energy, is setting new standards for sustainable energy supply in large logistics centers and is considered a model for other ports, infrastructure projects and industrial facilities. Project partners include the Fraunhofer Institute UMSICHT, Westenergie Netzservice GmbH, Netze Duisburg GmbH, Stadtwerke Duisburg AG, and Stadtwerke Duisburg Energiehandel GmbH.

“The launch of this carbon-neutral energy system at the Duisburg Gateway Terminal is a big step toward a more climate-friendly, resilient energy supply. Together with our partner duisport, we’re showing how scalable technologies from Rolls-Royce can really help transform critical infrastructure – and help make the energy transition happen,” said Dr. Jörg Stratmann, CEO of Rolls-Royce Power Systems.

Note.

  1. It is carbon-neutral.
  2. The system uses both hydrogen and solar power.
  3. What has been created at the Port of Duisburg is considered by the German Federal Ministry for Economic Affairs and Energy to be a model for other ports, infrastructure projects and industrial facilities.
  4. It surely must help sales, that the flagship project is up and running.

In November 2021, I wrote about this project in Rolls-Royce Makes Duisburg Container Terminal Climate Neutral With MTU Hydrogen Technology, which included this graphic.

It seems that Heathrow Airport could have a use for this technology.

I have one important thought.

Where Will The Port Of Duisburg Get The Hydrogen It Needs?

In the graphic an Electrolyser and H2 Storage are clearly shown, as are the two H2 Combined Heat and Power Units.

So it looks like the Port of Duisburg will be generating their own green hydrogen.

Alternatively in April 2021, I wrote Uniper To Make Wilhelmshaven German Hub For Green Hydrogen; Green Ammonia Import Terminal.

Uniper’s plans for the Wilhelmshaven hydrogen hub include a 410 MW hydrogen electrolyser.

The Germans are also developing a project called AquaVentus to bring green hydrogen to Germany from the North Sea.

I asked Google AI, where AquaVentus would make landfall in Germany and got this answer.

The AquaVentus project’s planned offshore hydrogen pipeline, AquaDuctus, is intended to make landfall in the greater Wilhelmshaven or Büsum area in Germany, according to the AquaDuctus website. This pipeline is part of a larger plan to transport green hydrogen produced from offshore wind farms in the North Sea to the German mainland for distribution and use.

Wilhelmshaven and Duisburg is 194 miles.

Hydrogen could be delivered onward from Ludwigshaven to Southern Germany by a pipeline network called H2ercules.

I asked Google AI if the H2ercules hydrogen pipeline will connect to Duisburg and got this answer.

Yes, the H2ercules hydrogen network will connect to Duisburg. Specifically, a new 40-kilometer pipeline will be constructed from Dorsten to Duisburg-Walsum, connecting to the steelworks there, as part of the GET H2 pipeline extension according to thyssenkrupp Steel. This connection is part of the larger H2ercules project, which aims to create a hydrogen infrastructure backbone for Germany and beyond. The pipeline is scheduled to be operational in 2027, with thyssenkrupp Steel being connected in 2028.

It would appear that at some date in the not too distant future that the Port of Duisburg could be powered by green hydrogen from the North Sea, imported into Germany at Wilhelmshaven.

The German plans for hydrogen are extensive and it appears that the Port of Duisburg could have two sources for the hydrogen it needs.

25-Year-Old Danish Offshore Wind Farm Gets Approval To Operate For 25 More Years

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

This is the sub-heading.

After approving the production permit extension for the Samsø offshore wind farm earlier this month, the Danish Energy Agency (DEA) has now granted extended permits to two more of Denmark’s oldest offshore wind farms, Middelgrunden and Nysted.

These first two paragraphs add more details.

To support its decisions, the DEA has requested that the applicants for the production permit extensions deliver an impartial analysis of the remaining lifetime. After receiving the extensions, the owners are now obliged to carry out comprehensive annual service inspections.

The Middelgrunden offshore wind farm was built in 2000 and received its electricity production permit the same year, before full commissioning in March 2001. The DEA has now approved Middelgrunden to operate for 25 more years.

This must be a very good thing, if with a good well-planned maintenance regime, engineers can get a productive life of fifty years out of an offshore wind farm.

With nuclear power stations, engineers seem to be able to predict their life expectancy fairly well, so if we can do the same with wind farms, it must make the planning of future power capacity a lot easier.

I asked Google for an answer to how long do nuclear power stations last and got this AI Overview.

Nuclear power plants are typically designed to operate for 40 to 60 years, but some can be extended to 80 years or even longer with upgrades and maintenance. Early plants were often designed for 30 years, but many have been refurbished to extend their operational life, according to the World Nuclear Association. The actual lifespan can also depend on factors like financial viability, operating costs, and the need for decommissioning, according to the National Grid Group.

As I suspect that solar farms could remain productive for fifty or sixty years, a mix of nuclear, solar and wind should serve us well in the future. Especially, as every next generation of nuclear, solar and wind power should be better than the last.

As a very experienced mathematical modeller, I like it.

Offshore Solar Farm Ready For Tow Out To Hollandse Kust Noord Wind Project

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

This is the sub-heading.

What is described as the “world’s first” offshore solar farm integrated within a wind farm has completed assembly at the Port of Amsterdam and is ready for deployment at the Hollandse Kust Noord (HKN) offshore wind farm in the North Sea.

These two paragraphs give more details about the project.

Dutch company Oceans of Energy assembled the floating solar farm in three days. The system will be towed 18.5 kilometres offshore this summer to be installed at the HKN site, operated by CrossWind, a joint venture (JV) between Shell and Eneco.

According to Oceans of Energy, the project uses prefabricated floating solar units designed for offshore conditions and is seen as a step toward scaling hybrid wind-solar developments.

There are several ways to generate renewable energy.

As wind, solar, tidal and wave power are often out of phase with each other, if you are using two together in a hybrid setup, then it is probably not a bad idea to add a BESS or other form of storage to the mix.

In Oceans of Energy To Build Offshore Solar Array At Hollandse Kust Noord Offshore Wind Park, I said that the Dutch were putting batteries in the design of Hollanse Kust Noord offshore wind farm.

E.ON Invests £4 million In Allume Energy To Boost Solar Rollout For Flats

The title of this post, is the same as that of this article on Solar Power Portal.

These three paragraphs explain the deal and say a small amount about Alume’s SolShare system.

Energy supplier E.ON UK has today (17 June) announced that it has signed a strategic investment agreement with Australian firm Allume Energy to help the firm expand into the UK.

E.ON UK has invested £4 million into Allume Energy to enable Allume to expand the reach of its SolShare technology within the UK market. SolShare allows solar energy from a single rooftop solar PV installation to be fairly shared amongst multiple homes in the same building in order to allow residents of flats to access solar PV energy.

Residents are supplied their energy when they are using by a pre-determined allocation, allowing them to lower their energy bills. Many blocks of flats that do have solar panels fitted currently only use this energy to power the common areas of the building while residents still pay their full electricity bill. According to Allume, a shared rooftop solar PV system can reduce resident energy bills by between 30% and 60%.

I must say, that when I read this article, it had something of the too-good-to-be-true about it.

But.

  • My solar installation on a fair-sized roof cost me about £6,000 and I am constantly surprised at how much electricity it provides.
  • If you have fifty flats, they all won’t do their weekly washing at the same time each week.
  • I wouldn’t be surprised to see a big battery somewhere or a small battery in each flat.
  • The batteries could soak up any excess electricity or charge on cheap-rate overnight electricity.
  • Do Allume’s engineers go through every flat and make suggestions about saving energy?
  • Is the pattern of electricity usage in a block of flats predictable from past usage and factors like weather, the time of the year and what’s on television?
  • I wouldn’t be surprised that Allume have performed extensive mathematical modelling on blocks of flats.

I think this deal could be a winner foe E.ON, Allume and their customers.

I have some ideas about the use of the system.

Would It Work On A Small Housing Estate?

A small housing estate would be a number of solar roofs feeding a number of houses, whereas with flats it will be one roof feeding a number of dwellings.

I suspect that with a well-designed sharing and pooling system, a lot of features of the flat-powering system could be used to power houses.

How Does The System Handle Electric Vehicles?

The system could use these to store electricity, so that they are always charged at the cheapest rate.

And when there is a shortage of electricity, the electricity could be borrowed by the Allume system.

Conclusion

If you have community sharing their own source of electricity, you can probably make ideas work, that wouldn’t in a single application.

My nose says Allume’s idea has legs.

UK Solar Capacity Up 5.9% Year-On-Year

The title of this post, is the same as that of this article on the Solar Power Portal.

These first two paragraphs give a flavour of the comprehensive solar generation statistics in the article.

The latest data from the Department for Energy Security and Net Zero (DESNZ) has revealed that both domestic and non-domestic solar installations are continuing to rise in the UK.

As of the end of April 2025, the UK has a total of 18.1GW of solar capacity across 1,780,000 installations; this marks an increase of 5.9% (1GW) since April 2025. In April of this year, 20,405 new solar installations with a combined capacity of 82MW were completed, a figure which DESNZ notes is higher than the average figures seen between 2016 and 2021.

The article is full of interesting statistics and deserves a detailed read.

I was surprised that ground-mounted solar to accounted for approximately 59% of the UK’s total solar capacity.

At the end of the article it is pointed out that that between 2010 and 2015, the average time for a project to get approval sat at around 29 weeks; in the past five years, the average wait time for approval has increased to 45 weeks, with the current longest time for a project to go through the Local Planning Authority approval process standing at 177 weeks.

It does appear that project delays are increasing faster than the UK’s solar capacity.
