Centrica To Invest In Fund Backing The Technologies Driving The Energy Transition
The title of this post, is the same as that of this press release from Centrica.
This is the sub-heading.
Centrica has made a $13.5 million anchor commitment to the first close of ERV Fund II, a new fund from London-based venture capital firm Energy Revolution. The fund is targeting US$50 million and invests at Seed and Series A in energy storage, grid technology and advanced materials.
These two paragraphs add more details.
The electrification of transport, heating and industry, alongside the rapid growth of data centres, is accelerating demand for electricity. That is putting greater pressure on the grids, storage systems, and materials needed to generate, move and deliver reliable power.
Founded in 2021, ERV Group backs early-stage energy technology companies through ERV Fund II and its venture builder, Prosemino. Its technical committee is led by three UK experts: Professor Paul Shearing, Director of the Zero Institute at Oxford University; Professor Chris Howard, Professor of Materials Physics at University College London; and Daniel Brett, CEO of Sention Technologies and formerly co-head of UCL’s Electrochemical Innovation Lab. The firm also has seven full-time PhDs across its technical team.
It looks to me, that this is a good long-term strategy from Centrica.
Centrica, X-energy Advance Nuclear Plans As UK Regulators To Begin Design Review For Xe-100
The title of this post, is the same as that of this press release from Centrica.
This is the sub-heading.
On the one-year anniversary of the Centrica X-energy partnership being signed, the UK Government has directed regulators to accept the X-energy Xe-100 Advanced Modular reactor into the Generic Design Assessment, marking a significant step toward UK commercial licensing.
Under their partnership, the companies intend to deploy up to 6 GW of new nuclear capacity in the UK (10-20 Xe-100 power stations depending on size of each installation)
These first two paragraphs add some details.
Centrica and X‑Energy, Inc., a leading developer of advanced nuclear reactors and fuel technology, today announced that X‑energy’s Xe‑100 Generation IV advanced Small Modular Reactor (“SMR”) has been accepted into the United Kingdom’s Generic Design Assessment (“GDA”) process.
GDA acceptance formally triggers the process of assessing the design’s acceptability for deployment and operation ahead of the technical and environmental evaluations required for site‑specific licensing and permitting. The assessment is expected to take approximately three years and will be administered by the UK Office for Nuclear Regulation (“ONR”), the Environment Agency (EA), and Natural Resources Wales
To learn more, I asked Google AI for what it knows on the Xe-100 reactor and I received this.
The Xe-100 is an advanced Generation IV high-temperature gas-cooled pebble-bed small modular nuclear reactor developed by the American company X-energy.
Key Specifications & Design
Power Output: Generates about 80 megawatts of electricity (MWe) or 200 MW thermal per unit, and can be scaled up into a four-pack configuration yielding 320 MW.
Cooling System: Uses inert helium gas instead of water to remove heat from the core, reaching operating temperatures above 750°C.
Fuel Type: Runs on proprietary TRISO-X fuel pebbles, where each billiard-ball-sized pebble contains roughly 18,000 microscopic TRISO fuel particles that act as individual containment vessels.
Note.
- 320 MW may seem small, but you have to remember Sizewell A was two 210 MW Magnox reactors and it operated for forty years.
- I like the choice of helium for a coolant. Especially, as the gas is widely used for cooling superconducting magnets, so there must be plenty of expertise.
- Helium is also present in the atmosphere at 5.2 parts per million.
- I also like the concept of the fuel pebbles.
These are some of my questions.
Where Was TRISO Fuel Developed?
The Wikipedia entry for TRISO Fuel has a History section, which starts with this paragraph.
Coated-particle ceramic fuels were initially developed in the United Kingdom as part of the Dragon reactor project. During the development of the Dragon reactor, its designers became concerned by the need to purge gaseous fission products from the reactor core and their potential migration to other parts of the reactor This concern led to the choice of coated-particle fuel, where the fuel would be formed from small particles of uranium then coated with pyrolytic carbon. The inclusion of silicon carbide as a diffusion barrier was first suggested by D. T. Livey in 1961, in order to better retain fission products.
Note.
- The United States and Germany made contributions to the development of TRISO fuel.
- the first commercial reactor to use TRISO, was the 330 MWe Fort Saint Vrain Nuclear Power Plant
- The experimental High Temperature Test Reactor in Japan, constructed in 1998, uses prismatic UO2 TRISO fuel.
- Japan has the only TRISO-fueled reactor in commercial operation.
- Oak Ridge National Laboratory in the United States, developed the process used to make TRISO fuel.
The Wikipedia entry for the Dragon reactor is worth a read.
These are the first two paragraphs of its Wikipedia entry.
Dragon was an experimental high temperature gas-cooled reactor at Winfrith in Dorset, England, operated by the United Kingdom Atomic Energy Authority (UKAEA). Its purpose was to test fuel and materials for the European High Temperature Reactor programme, which was exploring the use of tristructural-isotropic (TRISO) fuel and gas cooling for future high-efficiency reactor designs. The project was built and managed as an Organisation for Economic Co-operation and Development/Nuclear Energy Agency international project. In total, 13 countries were involved in its design and operation during the project lifetime.
Originally conceived as a small research reactor, during the design phase it grew larger. The choice of helium coolant was made after a long debate within the UKAEA between proponents of helium and carbon dioxide, with helium ultimately selected. Groundbreaking occurred in 1960. It operated from 1965 to 1976, and is generally considered extremely successful.
Who Are The Technology Partners Of X-energy?
I had to ask Google AI this question and received this reply.
X-energy works with major technology, industrial, and energy partners to develop and deploy its advanced small modular nuclear reactors (SMRs) and TRISO-based fuel technology.
Key Technology and Strategic Partners
Amazon and AWS: A primary investor (through the Climate Pledge Fund) and customer, Amazon collaborates with X-energy on scaling nuclear energy for data centers and AI infrastructure. X-energy, Amazon Web Services (AWS), NVIDIA, and Idaho National Laboratory are founding members of Project Prometheus to apply AI to advanced nuclear deployment.
NVIDIA: A founding partner in Project Prometheus alongside AWS and Idaho National Laboratory, helping integrate AI accelerators and tools into nuclear design and operations.
Doosan Enerbility & Korea Hydro & Nuclear Power (KHNP): South Korean industrial partners collaborating to support multi-gigawatt deployments of Xe-100 reactors and manufacture key components.
Energy Northwest: A utility partner working on X-energy’s first-of-a-kind project development in Washington state.
Dow Inc.: Partnered with X-energy to deploy an initial four-unit Xe-100 plant at Dow’s Seadrift chemical manufacturing site in Texas.
Centrica: Partnered through a Joint Development Agreement to deploy Advanced Modular Reactors and pursue up to 6 gigawatts of new nuclear capacity in the United Kingdom.
IHI Corporation: Partnered to expand U.S.-Japan supply chain collaboration and commercial-scale manufacturing for reactor components.
Oak Ridge National Laboratory: Collaborates with X-energy’s fuel subsidiary, TRISO-X, on advanced nuclear fuel research.
Note.
- There are companies and organisations here from Korea, Japan, the US and the UK.
- Do Amazon and Centrica see an Xe-100 reactor as a reliable way of powering a data centre without a grid connection?
- The Korean and Japanese companies would be ideal to ensure the quality of reactor and other key compoonents.
- Chemical manufacturing sites use a lot of electricity and Dow’s contribution could define a widespread use of the Xe-100.
- Oak Ridge have been a client of mine in the past and like AWRE in England, I would trust their nuclear technology.
I also believe that if you put these companies in a joint venture, you’ll get out more ideas than you expect.
Who Are The Financial Partners Of X-energy?
I had to ask Google AI this question and received this reply.
Amazon & Climate Pledge Fund: Led major funding rounds (including a $500 million investment in 2024 and ongoing backing) and holds a significant stake in the company.
Jane Street: Led X-energy’s oversubscribed $700 million Series D financing round.
Ares Management: Provided financial backing and funds across multiple investment rounds alongside special purpose acquisition sponsorships.
Emerson Collective: Participated as a key venture capital backer across multiple funding rounds.
NGP Energy Capital Management: Contributed significant capital through multiple financing stages.
Segra Capital Management: Acted as an ongoing financial participant in major capital raises.
Other Investors: Includes ARK Invest, Point72, Galvanize, Ken Griffin (Citadel founder), XTX Ventures, Reaves Asset Management, and the University of Michigan.
Note that like the technology, the finance comes from a wide variety of sources.
This all sounds like a good positive start.
Will Centrica, X-energy Be Going For A Multi-Country Design Review For Xe-100?
There are four major countries with extensive nuclear power experience, with stakes in the Xe-100; Japan, Korea, the US and the UK.
There is also Oak Ridge in the US, which appears to be supplying the concept of the fuel.
If this group can’t convince the regulators in these four countries, that they have a safe and viable project, then they shouldn’t be in business.
Conclusion
It’s now mainly up to the regulators.
Unfortunately, you get stories with titles like this article on the BBC, which have a title of Green Party Leader Criticises Nuclear Reactor Plan.
An Extreme Day Out – Bedlington And Northumberland Park Stations
This OpenRailwayMap shows the Northumberland Line and the Eastern part of the Newcastle Metro.
Note.
- The yellow track is the Northumberland Line.
- It terminates in the North at Ashington in the top-left corner of the map.
- Bebington station is indicated by the blue arrow.
- It terminates in the South at Newcastle station.
- The green track is the Newcastle Metro.
- There is now an interchange between the two lines at Northumberland Park station.
In the following sections, I’ll describe my trip.
King’s Cross And Newcastle Return For £66.35
I bought my two long distance tickets on a walk-up basis at King’s Cross and Newcastle stations from the machines.
- I traveled North on a Lumo service to Glasgow for £27.20.
- I did indulge myself with a tea for £2.60.
- I traveled South on an LNER service for £36.55.
- One of the reasons, I buy tickets on a walk-up basis, is that with my uncomplicated pancolonic diverticular disease, I might decide to cancel at the last minute, so it avoids the hassle of getting refunds.
Both services were within a few minutes of the timetable, although LNER had said they would be late, due to signalling problems.
My Route In Northumberland For £2.60
I bought a return ticket at Newcastle station for Ashington, which is the current terminus of the Northumberland Line.
- I actually didn’t go past Bedlington station, where I turned round and had a drink.
- As there are two trains per hour on the Northumberland Line, waits are not generally not too long.
- I only came back as far as Northumberland Park, where I swapped to the Metro for Newcastle station.
If I had had more time, I would have stopped at Seaton Delaval station to have a gluten-free dinner, which I wrote about in Seaton Delaval Station – 30th March 2025.
From Newcastle to Bedlington Station
I took these pictures going to Bedlington station.
I would have taken more pictures, but the train was rather full.
Bedlington Station And Bedlington
I took these pictures at and around Bedlington station.
Note.
- Although it is a completely rebuilt station, it has a level crossing.
- But is the signal box keeping a watchful eye over trains and the road?
- Bedlington station appears to be step-free using ramps and the level crossing.
- Just to the North of the station, the tracks split to Ashington and Morpeth.
In my forty minutes or so in Bedlington, I didn’t see a terrier.
Are Any Bedlington Terriers Still Bred At Or Near Bedlington?
I had to ask Google AI, this question and I received this reply.
Yes, Bedlington Terriers are still bred in and around their namesake town in Northumberland, UK. While they are a relatively rare breed overall, the historic North East region remains one of the primary strongholds for these distinct “lamb-like” dogs.
Northumberland Park Station
I took these pictures at Northumberland Park station.
Note.
- The Northumberland Line uses a single bi-directional platform on the North side of the station.
- The Newcastle Metro uses an island platform on the South side of the station.
- Both platforms have steps and lifts.
- There are around 400 parking spaces and a Sainsbury’s Superstore at the station.
At 78, after a stroke, I didn’t find the change between the two lines difficult. But I did use the lifts!
What Are The Future Plans For The Northumberland Line?
I couldn’t resist asking Google AI this question and I received this answer.
With the Bedlington and Northumberland Park stations fully operational, the core phase of the Northumberland Line connecting Ashington to Newcastle is complete. Future plans now focus on route extensions, additional stops, and increasing capacity to handle high passenger demand.
Key Future Plans
Extension to the Coast: The North East Combined Authority is actively funding the development of an extension to Newbiggin-by-the-Sea, utilizing existing freight tracks. Planning submissions for this expansion are targeted for 2028.
New Station Proposals: Proposals are being explored to build an additional stop serving the Wansbeck General Hospital and to replace the long-closed Choppington station.
Increased Capacity: Operator Northern Rail is in ongoing discussions with transport partners to lengthen train services (which are currently constrained to two to four coaches) to help accommodate massive patronage on the line.
Integrated Ticketing: The Northumberland County Council is exploring integrated ticketing with the Tyne and Wear Metro to allow for seamless travel between the two networks at stations like Northumberland Park.
From my observations on the line over the last few years, I would go along with Google AI’s recommendations.
These are some specific thoughts.
Extension To Newbiggin-by-the-Sea
This OpenRailwayMap shows the tracks that used to exist between Ashington and Newbiggin-by-the-Sea.
Note.
- Ashington station is in the South-West corner of the map.
- A freight line exists, which is shown in yellow, all the way to Lynemouth power station, which is a 420 MW biomass power station.
- Lynemouth powerstation was originally built to power an aluminium smelter.
- Running South-East from the Northumberland Line, is a disused railway alignment labelled NBN, which leads into Newbiggin-by-the-Sea.
This Wikipedia section describes the history of railway connection of the town.
Situated on the west side of Front Street (now the B1334), the station opened on 1 March 1872 as a terminus of the Blyth and Tyne Railway (now known as the Northumberland Line). The station had a long island platform onto which the station building faced. There were sidings on both sides of the station which handled goods traffic, controlled by a signal box. The station closed to both passengers and goods traffic on 2 November 1964. With the reopening of the Northumberland Line, Provisions have been made, especially at Ashington so that the line could be extended to Newbiggin. As of the end of 2025, there were calls to extend the railway by 1.6km (1 mile) into the centre of Newbiggin-by-the-Sea. This will require new track and is all subject to a feasibility study. A formal bid was launched in December 2025 for this.
In Formal Bid To Extend Railway Line, I wrote about the latest progress in January 2026, based on a BBC article.
The Northumberland Line Needs A Focus Other Than Commuting
Several of the stations have large car-parks, which is good for commuting, but the railway needs to serve more places for leisure and other activities.
- Seaton Delaval Hall is Grade 1 Listed and is just 10 minutes in a bus from the station with the same name.
- If the Northumberland Line is connected to Newbiggin-by-the-Sea, that could bring in those, wanting a day by the sea.
- The extended Northumberland Line would also connect to Woodhorn, which is a museum, described in this Wikipedia entry.
QTS are also developing an AI data centre at Cambois, which surely will generate commuter traffic from all over the North East.
This OpenRailwayMap shows the location of the QTS AI Data Centre.
Note.
- Ashington station is indicated by a blue arrow.
- The yellow track is the Northumberland Line, which now terminates at Ashington station.
- Bedlington station is in the South-West corner of the map.
- The trapezoidal grey box to the East of Bedlington is labelled as Site for QTS AI Data Centre.
- As the site, was that of Blyth coal-fired power station, before QTS acquired it, there is a disused railway line that connects the site to the Northumberland Line.
I suspect there are powerful economic arguments about whether or not, the Northumberland Line is extended to the QTS AI Data Centre site.
How Much Power Will QTS Cambois Data Centre Need?
I couldn’t resist asking Google AI this question and I received this answer.
The proposed QTS Cambois data centre in Northumberland is expected to require between 620MW and 720MW of critical IT power capacity, with an initial proposal capacity of up to 1.1GW.
Details on the planned power infrastructure include:
Power Capacity: The facility will support up to 720MW of critical IT capacity across ten planned buildings, though some council estimates cite an expected total power capacity of 620MW.
Backup Power: To guarantee uptime and handle power outages, the campus will rely on nearly 600 diesel-powered generators, requiring up to 58 generators per data hall.
Site Details: Located on the former Blyth Power Station site in Cambois, the £10 billion development will span 540,000 square metres.
My views on this are.
- There is the 1.4 GW North Sea Link from Blyth to Norway, that I wrote about in UK To Norway Sub-Sea Green Power Cable Operational.
- The 4.1 GW Berwick Bank wind farm is planned to send 1.8 GW to Blyth.
- To help if QTS need more power, there is the 1.4 GW Sofia wind farm.
- So 1.1 GW should be manageable, as Blyth is blessed with more power than Niagra Falls.
I also believe that Centrica and Delta have a much better backup solution, that I described in Delta And Centrica Launch Scalable Off-Grid Fuel Cell Power Solution. Hydrogen could come by pipeline or rail.
How Would The Northumberland Line Connect To Wansbeck Hospital?
This Google Map, shows the location of Wansbeck General Hospital with respect to Ashington station.
Note.
- Ashington station in the South-West corner.
- Woodhorn museum is in the North-East corner.
- Wansbeck General Hospital is indicated by a red arrow.
- The Northumberland Line runs East-West to the South of the museum and then curves round to reach the station.
Perhaps the station could go between the museum and the hospital and an innovative shuttle would connect all three locations.
How Would The Northumberland Line Connect To Choppington?
This Google Map, shows the location of Choppington, with respect to Morpeth and Bedlington stations.
Note.
- The orange track on the West side of the map is the East Coast Main Line.
- Morpeth station is in the North-West corner of the map.
- Bedlington station is in the South-East corner of the map.
The Eastern end of the Bedlington and Morpeth Line can be seen in this picture to the left of Bedlington North signal box at the Northern ends of the the platforms.
Note.
- Bedlington North signal box has a communication mast behind it.
- The track to the left of the box goes to Morpeth.
- The track to the right of the box goes to Ashington.
This OpenRailwayMap shows Choppington Road, which crosses the Bedlington and Morpeth Line at the only level crossing between Bedlington station and Hepscott junction.
Note.
- Choppington Road, which runs North-South on the map.
- The yellow tracks are the Morpeth and Bedlington Line, which runs East-West across the map.
- Where they cross, a red cross indicates a level crossing.
- The Wikipedia entry of Choppington station shows a level crossing.
As the level crossing on the map is the only one shown, this must be the location of Choppington station.
Can East Midlands Railway Reach Nottingham Without More Electrification?
I went to Nottingham for the day yesterday.
- My Super Off-Peak Return ticket cost me £55.30 with a Senior Railcard.
- The Class 810 train is without doubt the best Hitachi Intercity Express Train of a good bunch.
- St. Pancras and Nottingham is 126.4 miles.
- There is no electrification between South Wigston Junction and Nottingham, which is 31.1 miles, although the change seems to be said to take place at Kilby Bridge junction.
- It would appear that, when the Class 810 trains are fitted with batteries, they will need a range of at least 62.2 miles, to do a return trip to Nottingham.
- In The Data Sheet For Hitachi Battery Electric Trains, I state that the maximum range of a three-battery five-car train is 117 miles. This figure has been seen by Hitachi and they didn’t say it was too high.
- I look forward to doing the same trip in a few months, using batteries to the North of the section between Kilby Bridge and South Wigston junctions.
It could be the first battery-electric 125 mph express train.
Now that is what I call affordable electrification.
I have some further thoughts.
Kilby Bridge And Wigston Junctions
This Google Map shows the Midland Main Line between Kilby Bridge and Wigston junctions.
Note.
- Kilby Bridge junction is marked by the red arrow in the South-East corner.
- The Midland Main Line runs through Kilby Bridge junction.
- South-East it goes to London.
- North-West is leads to the large triangular Wigston junction, with South Wigston station at its Western point.
- The Northern point of Wigston junction leads to Leicester.
- There are three tracks between Wigston and Kilby Bridge junctions.
- All tracks to the South of South Wigston junction are electrified.
- The distance between Wigston and Kilby Bridge junctions is two miles.
- The maximum speed between Wigston and Kilby Bridge junctions appears to be at least 100 mph.
It looks to me, that this section of track has been designed, so that trains can reliably raise and lower pantographs at the highest speed possible.
The Electrification Problem At Leicester
Some years ago I came back to London from Leicester with a group of drivers. At one point, the conversation turned to electrification and they said that they had met a Network Rail engineer, who had told them, that the bridge over Leicester station was rather low for electrification and the track couldn’t be lowered because Leicester’s main sewer was underneath the railway.
In Leicester Station – 4th Jan 2022, I show a selection of pictures of Leicester station’s Grade II Listed frontage.
I doubt it would be possible to seriously alter Leicester station to electrify it, as the Heritage Taliban would have a field day.
But if I’m right that all services will be run North of Wigston on batteries, there will be no need to electrify through Leicester station.
Not only would using battery-electric trains probably be more affordable than electrification, but also because of the Leicester electrification problem, it would be less inconvenient for passengers.
Changing From Electric Going North
This OpenRailwayMap shows the electrification between Wigston Junction and Leicester station.
Note.
- Leicester station is marked by the blue arrow.
- The triangular Wigston junction is clearly visible.
- Kilby Bridge junction is South-East of Wigston junction.
- Leicester station and South Wigston junction is 3.6 miles and the tracks are shown as dashed black and red, which means future electrification.
I wonder, if in the future, if the battery-electric don’t have enough range, this is a simple section of electrification, that could be installed. Every extra mile of electrification between Leicester station and South Wigston junction would mean two miles could be chopped from the distance the trains had to travel on batteries.
But in the interim, going North, the driver would just make sure there was enough electricity in the batteries and momentum in the train, when passing South Wigston.
As trains arriving at South Wigston junction will typically have been running for over an hour, they should have full batteries to start theur explore of the North.
Changing To Electric Going South
The trains from the North, must have enough juice in the battery to reach South Wigston, so they can connect to the electrification for the run to London.
Could A Four-Battery Class 810 Train Reach Sheffield?
Consider.
- St. Pancras and Sheffield is 164.7 miles.
- There is no electrification between South Wigston Junction and Sheffield, which is 89.4 miles, although the change seems to be said to take place at Kilby Bridge junction.
- It would appear that, when the Class 810 trains are fitted with batteries, they will need a range of at least 178.8 miles to do a return trip to Sheffield.
- If a three-battery five-car Class 810 train has a battery range of 117 miles, on a pro-rata basis a four-battery five-car will only have a range of 156 miles.
That would be a big ask.
Could A Three-Battery Class 810 Train Reach Sheffield?
What would happen if one diesel engine was still installed?
These are my thoughts.
- As a Graduate Control Engineer, I wouldn’t be surprised that Hitachi have a strategy to do this with a tri-mode version of the Class 810 train.
- Hitachi have already announced the Class 820 train for Grand Central Trains and this is a tri-mode version of their InterCity Express, which is described in this Wikipedia entry.
- As Grand Central have said that the Class 820 trains, will be replacing the Class 180 trains, that run to Bradford Interchange and Sunderland, a tri-mode Class 810 would surely be able to run to Sheffield.
Could East Midlands Parkway Station Be Used For Opportunity Charging?
This Google Map shows East Midlands Parkway station with the massive derelict Radcliffe-on-Soar coal-powered power station alongside.
Note.
- The Midland Main Line running North-South across the map.
- East Midlands Parkway station on its Western side.
- The derelict Radcliffe-on-Soar coal-powered power station on its Eastern side.
A vast site like this must have uses.
I asked Google AI,”What Are The Plans For Radcliffe-on-Soar Power Station?” and received this reply.
The former Ratcliffe-on-Soar power station site is undergoing a multi-year decommissioning and demolition process, lasting until at least 2030 or 2031, to be transformed into a zero-carbon technology, energy, and advanced manufacturing hub.
Key details of the redevelopment include:
Site Vision: The 273-acre brownfield site has been earmarked to become a major business hub focused on advanced manufacturing (e.g., electric car batteries), low-carbon energy production, energy storage, and AI-driven data centres.
Economic Status: The site is a core component of the East Midlands Freeport, which offers significant financial incentives to attract business investment and create an estimated 7,000 to 8,000 jobs.
Demolition Timeline: The first demolition works are expected to begin in 2026, with the iconic cooling towers and main chimneys scheduled for controlled demolition between 2029 and 2030.
Planning Framework: A Local Development Order (LDO) granted by Rushcliffe Borough Council is in place to fast-track the planning process for these modern, green-focused industrial uses.
As the site will need to be supplied with a reliable energy supply for some of the proposed uses, I suspect power could be supplied to electrify the lines through East Midlands Parkway station, so that trains going to the North could take the opportunity to have a Formula One-style “Splash-and-Dash!”
Would Opportunity Charging At East Midlands Parkway Station Allow Extra Destinations?
Holders of the East Midlands Franchise have in the past, served other destinations in the past, either with regular services or engineering or seasonal diversions.
Possible destinations could be.
Cleethorpes
Distance to South Wigston – 112.4 miles
Doncaster
Distance to South Wigston – 108.1 miles – But could top up at Doncaster.
Rotherham Central
Distance to South Wigston – 102.2 miles
Scunthorpe
Distance to South Wigston – 112.4 miles
Gas-Fired Power Still Looks A Safe Bet For Centrica In The Renewables Era
I feel rather surprisingly, the title of this post, is the same as this article on the Guardian.
You’d think, that they would be critical of Centrica for keeping the gas power stations going.
But this is the sub-heading.
There will still be a need to have gas in the wings to keep the lights on, so the financials stack up on Severn plant purchase.
So why should Centrica buy a 832 MW closed cycle gas fired power station?
These posts describe, what Centrica have done at Brigg with another closed cycle gas fired power station.
- Construction Under Way To Double Power Station Capacity At Centrica’s Brigg Energy Park
- Hydrogen Milestone: UK’s First Hydrogen-to-Power Trial At Brigg Energy Park
Will Centrica be taking closed cycle gas fired power stations and making them more efficient to provide the back up to wind farms, when wind is having an off day?
I wouldn’t be surprised, if Centrica put a big battery on the two sites, as after all they are a godparent to Highview Power.
Are there any more closed cycle gas fired power stations, that they can acquire?
I asked, Google AI,”How many closed cycle gas fired power stations are there in the uk?” and received this answer.
As of early 2026, there are approximately 35 active combined cycle gas turbine (CCGT) power stations—often referred to as closed-cycle—in the UK.
These plants provide the bulk of the UK’s gas-fired capacity, totaling roughly 30-35 GW along with smaller, single-cycle (OCGT) plants which are used for backup.
Total Capacity: The total capacity of all gas-fired generation (CCGT and others) is approximately 35.7 GW.
Role in Power Mix: CCGTs are highly efficient and provide baseload power, while OCGT plants (about 14+ sites) are typically used for peak demand.
Key Locations: Major plants include Pembroke (RWE), Staythorpe (RWE), Didcot B (RWE), and Connah’s Quay (Uniper).
These plants remain the largest single source of electricity generation on the UK grid, though they are increasingly being paired with carbon capture proposals.
I think, that Engineer Baldrick is now working for Centrica and he has a cunning plan to use efficient CCGT power stations to back up the wind.
Consider.
- Severn power station is an 832 MW combined cycle power plant running on natural gas, which is located near Newport in South Wales.
- 4.5 GW of offshore wind is to be built near Port Talbot.
- Will some hydrogen generated by HiiROC be used to part-fire Severn power station and reduce its carbon footprint.
- South Wales can easily find space for a couple of Highview 300 MW/3.2 GWh CRYOBatteries.
- It would be useful to have a good-sized hydrogen store in South Wales.
That mix would surely provide enough reliable power for green steelmaking and a few data centres.
The Former Unilever Site At Warrington – 6th May 2026
I went past this site twice yesterday on my way to and from Blackpool.
I took these pictures going Northwards.
And I took these pictures going Southwards.
A quick search of the Internet on my phone revealed.
- It was a former soap works, that had previously been owned by Unilever.
- The site was now going to be developed as a data centre.
This OpenRailwayMap shows the railways through the area.
Note.
- Warrington Bank Quay station is indicated by the blue arrow in the middle of the map.
- The Unilever site is to its North-West.
- Warrington Bank Quay station is a major station on the West Coast Main Line and will probably be on High Speed Two, which will share tracks with the West Coast Main Line.
- The two East-West lines are not electrified.
- Warrington West is a relatively new station, that I wrote about in 2020, in The New Warrington West Station.
This OpenRailwayMap shows the railway lines between Liverpool and the coast in the West and the West Coast main Line in the East.
Note.
- The Merseyrail third rail network shown in lilac.
- Electrified tracks shown in red.
- Tracks without electrification shown in black.
- Warrington Bank Quay station indicated by the blue arrow.
- The West Coast Main Line (WCML) runs North-South at the Eastern edge of the map.
- Wigan North Western station is in the North East corner of the map.
- Wigan North Western and Warrington Bank Quay stations are both on the WCML.
Five lines connect the Liverpool local network to the WCML.
- The top unelectrified line connects the new Headbolt Lane station to Wigan Wallgate station.
- The most Northerly electrified line connects Liverpool Lime Street and Wigan North Western stations via Huyton station.
- The second electrified line connects Liverpool Lime Street and Manchester via Newton-le-Willows station.
- The most Northerly of the bottom pair of unelectrified lines connects Liverpool Lime Street and Manchester via Warrington Central station.
- The final line is a freight line between Liverpool and Manchester along the Mersey. This line runs under the WCML
The last line is likely to be upgraded to become Northern Powerhouse Rail between Liverpool Lime Street and Manchester via Manchester Airport.
This picture shows a freight train passing under Warrington Bank Quay station.
This OpenRailway Map shows how the lines cross to the South of Warrington Bank Quay station.
Note.
- The electrified North-South line is the West Coast Main Line (WCML).
- There is quite a good amount of space.
Could the junction be designed, so that HS2 trains could go between Manchester and London?
Centrica Partners With Ceres Power On Solid Oxide Fuel Cells
The title of this post, is the same as this article on gasworld.
This is the sub-heading.
UK multinational energy and services company Centrica is partnering with clean tech firm Ceres Power to accelerate solid oxide fuel cells [SOFCs] production to meet forecasted ‘multi-gigawatt’ demand from industrial customers across Europe.
These three paragraphs indicate the market opportunity, that Centrica feel, that the partnership will fill.
With electricity grid connection delays impacting new industrial, commercial and digital projects, the UK and Europe are experiencing a widening gap between demand and available capacity.
Centrica aims to offer customers high‑efficiency, low‑carbon, grid independent on‑site power that can be deployed much faster than gas turbines or nuclear.
Group Chief Executive Chris O’Shea said by collaborating with Ceres’ technology it sees an opportunity to support data centres, AI and industry with cleaner power at scale. Ceres claims SOFCs can be manufactured and delivered on site to get power online “in months not years”.
It certainly sounds feasible to drop in an appropriate-sized stack of fuel cells and connect them up to the gas main.
These two paragraphs, indicate how Ceres will support Centrica.
Initially, Ceres will support Centrica in expanding a new differentiated service-led model for clean power, providing access to British technology through its expanding network of global manufacturing partners.
Ceres will assist Centrica with opportunities across project origination, installation and commissioning, remote monitoring, predictive maintenance and end of life recycling.
I have a few questions for Google AI.
Do Ceres Fuel Cells Emit Carbon Dioxide?
Google AI replied this.
Yes, Ceres Power has developed Solid Oxide Fuel Cell (SOFC) technology, known as the SteelCell®, that works on natural gas. This technology is specifically designed to be fuel-flexible, capable of converting grid natural gas into electricity at high efficiency.
Key Details About Ceres Fuel Cells and Natural Gas:
Technology Capability: The Ceres SteelCell runs on natural gas, as well as future-focused fuels like hydrogen and biogas.
Application: These fuel cells are used for distributed power generation in homes, businesses, and industrial settings (such as AI data centres).
Efficiency: When running on natural gas, the SOFC systems can achieve an electrical efficiency of around 62%, with total efficiency exceeding 90% when combined with heat recovery.
Emission Reductions: Compared to conventional combustion engines, the technology offers a 30% reduction in carbon emissions.
Current Strategy: As of early 2026, Ceres is focusing on natural gas-fueled SOFCs for stationary power markets, particularly in collaboration with partners like Centrica to address power shortages in the UK and Europe.
While the systems can be used for hydrogen in the long term, they are currently fully functional with natural gas, making them a “bridge” technology for decarbonisation.
A 30% reduction is surely worthwhile!
In What Size Are Ceres Power Holdings Fuel Cells Manufactured?
Google AI replied this.
Ceres Power Holdings’ solid oxide fuel cell (SOFC) technology is manufactured in modular, scalable sizes, with individual stacks ranging from 10-50 kW and commonly deployed in 1-5 MW power modules. These stacks are produced at manufacturing facilities with capacities like 50MW (e.g., with partner Doosan), with plans for up to 100MW annual capacity.
Key manufacturing and size details include:
Cell Component: 30–150W.
Stack: 10–50 kW.
Stack Array/Module: 100–500 kW, up to 1-5 MW modules.
Manufacturing Capacity: 50MW production facility in South Korea (Doosan), with plans for 100MW+ annual capacity in future plants.
Applications: Primarily stationary, distributed power systems for AI data centres, industrial decarbonisation, and commercial buildings.
Ceres licenses its technology to partners like Bosch and Doosan, with cell technology based on low-cost printed steel substrate
How Much Power Does A Top Of The Range MRi Scanner Use?
I am asking this question, as it is surely something you might power with a Ceres fuel cell powered by natural gas.
Google AI replied this.
A top-of-the-range MRI scanner (such as a 3-Tesla or 7-Tesla system) is highly energy-intensive, consuming substantial power 24/7 to maintain its superconducting magnet. During active scanning, power usage often ranges from 25 kW up to 80 kW or more.
Here is a breakdown of the power consumption for high-end MRI scanners:
Power Consumption Breakdown
Idle/Stand-by Mode (24/7): The machine constantly consumes roughly 6 to 7 kW for background cooling (liquid helium refrigeration).
Standard Scanning: Productive scanning sessions typically demand around 25 kW.
High-Demand Scanning: Demanding examinations (e.g., head examinations with EPI sequences or special angles) can cause power usage to surge to 70 kW to 80 kW.
System Total: A 3T MRI, including cooling systems (chillers) and peripheral electronics, might require a 3-phase, 480V, 200A supply—roughly equivalent to the capacity of six modern houses.
Conclusion
This seems to be a deal with a large number of possibilities.
Speaking from my past experience of banks and financing, where the bill is ultimately paid by a reputable individual or company like Shell or BP, I believe that Centrica will have no difficulty in financing lots of these systemsusing instiutions like Lloyds or Deutsche Bank.
Data Centre In The Shed Reduces Energy Bills To £40
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
An Essex couple have become the first people in the country to trial a scheme that sees them heat their home using a data centre in their garden shed.
These three introductory paragraphs add some detail.
Terrence and Lesley Bridges have seen their energy bills drop dramatically, from £375 a month down to as low as £40, since they swapped their gas boiler for a HeatHub – a small data centre containing more than 500 computers.
Data centres are banks of computers which carry out digital tasks. As the computers process data, they generate lots of heat, which is captured by oil and then transferred into the Bridges’ hot water system.
Mr Bridges, 76, says keeping his two-bed bungalow near Braintree warm was a necessity as his wife has spinal stenosis and is in “a lot of pain” when it gets colder.
I think this simple idea is absolutely brilliant and very technically sound.
Here are some further thoughts.
It Would Be Ideal For A House Like Mine
My house is a modern three-bedroomed house with a garage and when I asked Google AI how many UK houses had garages, I received this answer.
Approximately 38% of dwellings in England have a garage, according to a 2020 report. While a specific UK-wide figure is not available, extrapolating this percentage to the total number of UK dwellings suggests there are over 10 million houses with garages, though the actual figure may vary across different regions.
Looking at the picture in the BBC article, I feel that this HeatHub could fit in my house.
I would expect that any house with a garage, a small garden or a big enough boiler space could accommodate a HeatHub.
Obviously, the house would need.
- A boiler, that provides heating and hot water.
- A good broadband connection.
My house has both.
Would My House’s Heating System Need To Be Modified?
It looks like it’s just a boiler replacement, so I don’t think so, but it may need to be moderbnised with digital controllers to get the best out of the system.
Will There Be Other Systems Like Thermify’s Heat Hub?
Some of our electricity suppliers seem very innovative and the market is very competitive.
Would they just sit back and let coompetitors take their customers? I doubt it!
So I suspect there will be other systems, each with their own features.
I have already, written about heata, which uses similar principles to give affordable hot water in British Gas Partners With heata On Trial To Reuse Waste Heat From Data Processing.
The BBC article gives some examples of data centres used to provide heating, so it is worth reading the full article.
What Caused The Amazon Web Services Failure?
This article on Reuters is entitled Amazon’s AWS Struggles To Recover After Major Outage Disrupts Apps, Services Worldwide, sums up today’s big news story.
But what went wrong?
I asked Google AI, where BT have their data servers and received this reply.
BT hosts its data servers in various locations across the UK, including London, Birmingham, and Dublin, Ireland, as well as in mainland Europe such as Frankfurt, Germany, and Amsterdam and Nieuwegein, Netherlands. They also have a presence in the United States, with facilities in locations like New Jersey.
Note.
- Nieuwegein is South of Amsterdam.
- There’s almost a direct straight-line route between Dublin and Frantfurt.
- Cambridge would lie on that straight-line route.
- BT’s Research at Martlesham in Suffolk would lie on that straight-line route.
- Is BT’s worldwide network closely monitored from BT Research?
- For more about BT Research read their Wikipedia entry.
- The straight-line route by-passes London.
The network seems comprehensive and well spread-out.
These are my thoughts.
The Value Of Research
I asked Google AI, if there were any spin-out companies from BT Martlesham and received this reply.
Yes, spin-out companies have been formed from BT’s Adastral Park research facility, including Real Time Content (RTC) and iome. Both companies were supported by BT and developed technologies based on research from the Martlesham site, with RTC focusing on personalized video services and iome providing location-based services through mobile internet.
I used to live near to BT’s Research Centre until 1990.
At the time, I was writing Artemis, the project management system and the multi-user version of that software and a BT research computer system used the same Hewlett-Packard hardware and an operating system written by BT at Martlesham.
Because of this connection, I learned a lot about their methods and the breadth of the research being carried out in Suffolk and was generally impressed.
I would suspect that legacy telecom companies like BT, France Telecom and Deutsche Telecom spend a lot of money on research. Do newer companies spend similar amounts?
Having a good research department behind you is an excellent form of insurance!
Will BT Research Have A Reliable 24/7 Power Supply?
Consider.
- By 2030, there will be upwards of 4 GW of offshore wind power along the Suffolk coast.
- Sizewell B will be 22 miles away, pumping out 1.2 GW until at least 2035.
- Sizewell C could be pumping out 3.3 GW from the mid-2030s.
- The 1.8 GW LionLink between Walberswick in Suffolk and The Netherlands could be in operation by 2030.
I am fairly sure that BT Research will have enough power, even if several data centres are built on the Martlesham site.
The Domain Name Res0lution Problem
Consider.
- The root causeof Amazon’s disaster appeared to be problems with its domain name resolution system.
- Executing fast lookup of domain names is critical.
I had a similar problem with the project management system ; Artemis, when I extended it to be one of the first relational databases in the 1980s. So I went to IBM’s library on the South Bank and dug out all their 1950s papers on looking up keys in tables.
In those days, with slower computers, which had smaller amounts of memory, the efficiency of the algorithm was very important and I got a significant improvement in look-up speed, by digging up ideas from the past.
If anybody wants to check out their algorithm with me, I’m always happy to oblige, but at 78 with poor eye-sight I’m probably past coding anything myself.
When I was dealing with BT Research, they would have made sure that something like domain name resolution was given the full research treatment.
My Conclusion
As I don’t have all the data, I will not speculate, but will await Amazon’s conclusion with interest.
