Electric Open-Top Bus In Oxford – 24th September 2026
I hadn’t intended to write about these buses from Wrightbus today, but Oxford is a lot easier to get to than Glasgow, which also has these buses.
I took these pictures.
Note.
They seem to run about every fifteen minutes from the station.
I am rather surprised that only Glasgow, London and Oxford have battery-electric open-top buses. I thought more mayors had big egos!
This article on the BBC is entitled Oxford Sightseeing Fleet Gets Eight New Electric Buses, gives more details.
Between Oxford And Reading Stations – 24th September 2026
Returning from Oxford to Reading, I took a nine-car Class 800 train, that was travelling between Oxford and Paddington stations.
- It was pathed at 125 mph.
- It only stopped at Reading.
- It was running on diesel
- I was sitting on the left side of the train in the sixth coach.
These are some pictures I took out of the window.
Note.
- There seems to be a lot of car parking at Oxford station.
- The Student Castle Oxford is student accommodation and has this Internet link.
- The Cowley Branch leads to BMW’s Mini factory and is being updated to a two-station branch for passenger trains as well.
- The Cowley branch appears to be double track, which should allow for two trains per hour, which is the initial desired frquency.
- There appears to be signs of more electrification.
- There is a solar-powered sewage farm as you approach Reading.
I am very puzzled about image of an electrification stanchion between Oxford station and the Cowley branch.
Consider.
- Between Oxford North junction, where the Chiltern Line joins the Cotswold Line and the Cowley branch is about 3.5 miles and takes about seven minutes, with a stop at Oxford station.
- The Cowley branch is only three miles long.
- There are also some electrification stanchions between the Cowley branch and the Great Western Main Line.
- There are no signs of electrification work in Oxford station.
This OpenRailwayMap shows the Cotswold Line through Oxford station.
Note.
- The Cotswold Line through Oxford is shown in orange.
- There is no current electrification and original plans have been dropped.
- At the North-East corner of the map, the Chiltern Line joins from Oxford Parkway station at Oxford Canal and Oxford North junctions.
- The blue arrow marks Kennington junction, where the Cowley branch joins the Cotswold Line.
- The BMW terminal is at the Eastern edge of the map.
Chiltern Railway’s trains will need to go between Oxford Canal junction and the two stations on the Cowley branch and return.
Are There Any Plans To Electrify The Chiltern Line?
I asked Google AI this question and received this answer.
There are no fully funded or confirmed plans for complete electrification of the Chiltern Main Line, but Chiltern Railways and Network Rail are developing a business case for discontinuous electrification combined with battery-electric trains to replace the ageing diesel fleet from the early 2030s.
Current Plans and Decarbonisation Strategy
Discontinuous Electrification:Instead of wiring the entire route from London Marylebone to the West Midlands, the proposal relies on wiring select sections (such as north of High Wycombe towards Oxford or Banbury) to charge battery-electric rolling stock while avoiding costly bridge modifications and clearance issues.
Business Case Progress: Chiltern Railways has completed a strategic business case and is working with Network Rail and the Department for Transport (DfT) on an outline business case.
Interim Fleet Upgrades: As part of its 2030 Vision, Chiltern is introducing newly leased Mark 5A carriages to boost capacity and reliability, while continuing long-term discussions regarding a power supply and infrastructure package for cleaner trains.
It would appear to me, that if the Southbound line between Oxford Canal junction and Kennington junction, that this would be enough electrification to allow Chiltern’s Oxford services to serve the Cowley branch and return.
Could GWR’s Cotswold Services Be Run On Batteries?
Consider.
- Didcot Parkway and London Paddington is fully electrified.
- Battery-electric Class 800, 801 and 802 trains have an off-wires range of around 120 miles.
- Between Oxford and Great Malvern is 75.9 miles.
- Between Oxford and Hereford is 86.3 miles.
- Between Oxford and Worcester Shrub Hill is 57 miles.
I believe with charging at the country end, these services could be run using battery-electric Hitachi trains.
With Federal Funding Windfall, X-energy Advances Small Nuclear Reactor
The title of this post, is the same as this article on Canary Media.
This is the sub-heading.
The Amazon-backed firm is aiming to build up to 144 of its novel Xe-100 reactors as the U.S. government seeks to revitalize an industry beset by rising costs
These three initial paragraphs add more detail.
The federal government has thrown its weight into reviving America’s long-stagnant nuclear industry, and X-energy’s first-of-a-kind reactor project is among the biggest beneficiaries so far.
The U.S. Department of Energy last month said it would award $1 billion to X-energy, an Amazon-backed advanced nuclear startup working to bring four novel 80-megawatt electric reactors online at a Dow Chemical facility in Seadrift, Texas, in the early 2030s.
The award nearly doubles the federal government’s commitment to X-energy, following a $1.2 billion investment in early 2021. Both tranches were structured as 50-50 cost-sharing agreements under the DOE’s Advanced Reactor Demonstration Program, launched in 2020 to commercialize next-generation nuclear technologies.
Note.
- It looks like X-energy are well-funded.
- It also looks like they have received funding under two different presidents.
- I like Dow’s concept of using nuclear to power a chemical complex, which needs both lots of electricity and heat.
- If they build 144 reactors, this will be twelve of the 12-pack power station, that they have said they will build at Hartlepool and I wrote about in Hartlepool Nuclear Reactor Moves To UK Regulatory Assessment.
The next phase would appear to be up to the regulators.
The article on Canary Media is well worth giving a full read.
These are some important highlights.
Dow Seem Enthusiastic And Would Be An Ideal First Customer
In any large project the first customer is always important.
- Dow seem to fit the part well.
- I also suspect, that as Dow turned over around $40 billion in fiscal year 2025, they know what they want.
Even in nuclear power, the customer is generally right.
Has X-energy Found Any Customers For The Xe-100?
I asked Google AI, this question and received this answer.
Yes, X-energy has secured major commercial customers and strategic partners for the Xe-100 reactor.
Key Customers and Partners
Dow: Partnering to deploy an Xe-100 four-pack plant at the Seadrift chemicals manufacturing site in Texas to provide low-carbon heat and power.
Amazon: Bankrolling and collaborating on up to 12 Xe-100 units via Energy Northwest in Washington state, alongside broader clean energy scaling for AI infrastructure.
Centrica: Partnering in the UK to deploy a potential fleet of up to 6 GW (10 to 20 reactors), targeting the Hartlepool site.
Energy Northwest: A Washington public power utility working collaboratively on project deployment frameworks.
Note.
When, the four partners, of which I was one, started to develop the Artemis project management system, the salesman of the four, did a survey of who might buy.
A proportion of these became valuable clients.
As X-energy also has a world-class engineering partner from Japan and Korea, I feel that they have done their preparation thoroughly.
Where Is The TRISO Fuel To Be Made?
According to the Canary Media article, it will be made near Oak Ridge National Laboratory in Tennessee.
- This could be handy for support.
- It could ease recruiting some of the staff with the right experience.
- There may also be useful sub-contractors in the area, with the right experience and certification.
The location is an excellent one.
Has Centrica Been Recruited Because They Are British?
According to its Wikipedia entry, the Dragon reactor, which used TRISO fuel, was generally considered extremely successful.
So by inviting Centrica to be involved, will X-energy be able to get access to the British files concerning the details of the Dragon reactor?
Their interpretation may be the difference between success and failure of the project.
I wouldn’t be surprised that there is a very trustworthy and knowledgeable network of very elderly British nuclear engineers, who enjoy meeting in pubs, with only the best real ales.
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.
Can The Hiiroc Process Be Used To Make Sustainable Aviation Fuel (SAF)?
After Writing Cemex To Install World-First Hydrogen Process At UK Cement Plant, I just had to ask this question of Google AI and I received this reply.
Yes, the HiiROC process is currently being developed and studied to produce Sustainable Aviation Fuel (SAF).
How the Process Works
Thermal Plasma Electrolysis (TPE): HiiROC’s core technology splits hydrocarbons (like biomethane, natural gas, or flare gas) into clean hydrogen and solid carbon without burning them or emitting carbon dioxide.
Thermal Plasma Reforming (TPR): Building on TPE, this adaptation is being evaluated to create synthetic e-SAF by combining the produced clean hydrogen with carbon dioxide at a lower electricity cost than traditional water electrolysis.
Current Developments
Feasibility Study: HiiROC received grant funding from Scottish Enterprise to study a negative-carbon SAF business in Scotland through its subsidiary Zeleno Ltd and partner Stratus Energy Partners.
Partnerships: The initiative has drawn interest from aviation and energy stakeholders like Airbus, World Kinect, and the Forth Green Freeport to make power-to-liquid SAF more scalable and affordable.
It certainly seems it could be a possible route to SAF.
I should say, that when I worked at ICI at Runcorn, for a period, I had the privilege of sharing an office, with an elderly scientist, who before the Second World War, was closely involved in the development of polythene.
That was a long process, but in the end they got there, mainly because radar needed a top-class insulator for which polythene was the only solution.
Cemex To Install World-First Hydrogen Process At UK Cement Plant
The title of this post, is the same as that of this article on The Chemical Engineer from 2024.
These two paragraphs introduce the article.
CEMEX is set to trial a process developed by Hiiroc that uses plasma to produce hydrogen for greener industrial heat at its cement plant in Rugby, UK.
Cemex is finalising contract details now with UK-based process developer Hiiroc and expects to start engineering studies early next year with hydrogen production set for a “hard deadline” of January 2026. The cement major thinks the process is a better bet for producing hydrogen than water electrolysis because it requires 80% less electricity and wins out over steam methane reforming because it doesn’t produce CO2.
I believe that this process, which has its origins in Hull University, could revolutionise the manufacture of zero-carbon hydrogen.
The article describes its first big application at Cemex’s Rugby cement plant.
There are obviously issues to be solved and the article is mainly an interview with Alfredo Carrato, who is innovation advisor at Cemex Ventures.
These are some thoughts.
HiiROC Is Containerised
The article says this.
Carrato expects the changes required to integrate the process at the Rugby plant to be minimal. One or two of Hiiroc’s containerised process units will be plugged into the grid and pipes installed to carry hydrogen to the existing kiln where a new burner will be installed to combust the hydrogen producing heat to convert limestone to clinker.
It also says this.
If successful, the Rugby plant could see eight or nine of Hiiroc’s modules installed at the site, Carrato said.
There could be a lot of low-carbon cement coming out of Rugby.
But containerisation also means that any factory using natural gas for a lot of heat, can plug in a number of Hiiroc’s containerised process units and decarbonise.
Worldwide Expansion
The article says this.
“We do have plans to expand this across our operations worldwide for a number of reasons. Hydrogen certainly is a relevant vector that we are considering to decarbonise our operations. And second, the modularity of the solution allows for a quick deployment.”
Cemex Aim To Be Net Zero By 2050
The article says this.
Cemex has set itself a target of becoming net zero by 2050. The Hiiroc process can make use of biomethane so could allow Cemex to replace its use of fossil fuel natural gas. It could also use renewable electricity to power its plasma burners. In terms of output, the process produces carbon black which can be used as an additive in its cement-making operations or sold for use in tyres, rubbers, plastics, inks, and toners.
“Because of the stoichiometry, the volume of carbon black is pretty significant, meaning we are not able to take the entirety of what is produced. So, we need to figure out how to also monetise it.”
Hiiroc is searching for alternative markets too. It has partnered with researchers in Europe and the US to investigate how the carbon black from its process could be used in other applications including filters, soil enhancers, and animal feed.
Note.
- The process can run on biomethane, as well as natural gas and chemical plant flare gas.
- The carbon black could be a long-term problem, but I suspect a use will be found.
Having worked in integrated chemical plants, I believe innovative uses for both feedstocks and what to do with the carbon black will be found.
Water Stress
The article says this.
Carrato said: “We’re looking at not only the carbon footprint, but also the stress on water. Water electrolysis has a lot of water demand, whereas technology such as Hiiroc has none. In regions where there’s a lot of water scarcity, we believe that Hiiroc can move the needle [for industrial decarbonisation] way better than water electrolysis.”
Any water problems seem soluble.
Conclusion
Alfredo Carrato of Cemex Ventures seems to be enthusiastic about his charge.
London Stansted Powers Up New Solar Farm
The title of this post, is the same as this press release from Stansted Airport.
These paragraphs are the text of the press release.
London Stansted’s new on-site solar farm is now fully operational, marking a major milestone on its net zero journey.
The solar farm, the first of its kind at a London airport, has more than 24,000 panels and has been constructed and will be operated by Onsite Power, EDF power solutions’ C&I solar division, on land already owned by Stansted immediately to the east of the airport.
The panels can produce up to 17.2 MW of direct current (DC) power. Once converted, the solar farm can produce up to 12.8 MW of usable alternating current (AC) power which is supplied directly into the airport’s network. This enables the solar farm, on the sunniest day, to produce power equivalent to the airport’s peak demand.
Over a year, the solar farm will generate enough electricity to meet the annual demand of 7,000 houses, similar in number to the town of Saffron Walden.
The development is an integral part of London Stansted’s £1.1 billion transformation programme and has been designed to help meet the airport’s current and increasing electricity demands, including those associated with the growing use of electric vehicles.
The project will also support London Stansted’s commitment to achieve net zero carbon emissions from its direct airport operations by no later than 2038.
It would appear that this installation meets these criteria.
- The solar farm, on the sunniest day, can produce power equivalent to the airport’s peak demand.
- The airport has a suitable, easily accessible field or roof, where the solar panels can be installed.
- There is no mention in the press release of a battery, so I would also expect, that the airport has a good two-way grid connection, so that any excess electricity can be exported.
- In SSE Energy Solutions Powers Ascot’s Shift To Electrification With One Of UK Sport’s Largest Rooftop Solar Projects, I describe a project to put a solar roof on the grandstand at Ascot racecourse, which required no upfront funding. Did EDF organise the funding of this project, which is thirty times larger than Ascot’s solar roof?
It also appears that the installation incorporates a degree of future proofing.
A Land Rover Defender Ambulance
This ambulance was parked outside the Red Cross in Moorfields, whilst I ate my breakfast in the LEON opposite.
Note.
- It was from the Lincolnshire Red Cross.
- It was a very professional conversion.
- Judging by the sign it appeared to be promoting the link between Jaguar Land Rover and the Red Cross.
As an occasional user of an ambulance, I have some views on the design of these vehicles.
Should Ambulances Be Hydrogen Powered?
I asked Google AI this question and received this answer.
Hydrogen power offers significant advantages for ambulances by combining long driving ranges with rapid refuelling times, making it a strong contender for emergency fleets.
The Case For Hydrogen Ambulances
Fast Refuelling: Hydrogen tanks can be refuelled in about five minutes, keeping vehicles ready for back-to-back emergency shifts without long charging downtimes.
Longer Range: Fuel cell and battery hybrid setups (like the ZERRO project) can travel up to 300 miles, which is vital for rural areas or long-distance hospital transfers.
Onboard Power: Hydrogen fuel cells can power heavy medical equipment without draining the main drive battery or requiring extra diesel generators.
The Challenges
Infrastructure Costs: Public hydrogen refuelling stations remain scarce, limiting where vehicles can operate and refuel.
Vehicle Costs: Building and buying hydrogen fuel cell systems is currently more expensive than standard battery-electric or diesel setups.
Electric Competitiveness: Standard battery-electric ambulances are already performing well in urban areas where depots allow for overnight recharging and shorter daily shifts.
Note.
- I have been a passenger in about four or five hydrogen fuel cell-powered buses. All were mouse-quiet with no vibration. This is surely important in an ambulance!
- I used to live next to a London paramedic sixty years ago and he said it was a stressful job. Would a calm environment help to relieve that stress?
- The onboard power capability is surely important and will get more important in the future.
- As more hydrogen-powered vehicles appear on the roads, hydrogen fuelling stations will be less scarce.
The long-range of a hydrogen-powered ambulance might mean that patients were taken to an appropriate hospital immediately.
How Does The Performance Of Electric-Powered And Hydrogen-Powered Ambulances Compare?
I asked Google AI this question and received this answer.
Electric-powered and hydrogen-powered ambulances compare across range, refueling time, energy efficiency, and onboard power capabilities:
Range and Operational Capacity
Electric Ambulances (BEV): Typically offer a range of around 70 to 120 miles on a single charge, which suits local response cars, patient transport, or shorter urban shifts.
Hydrogen-Electric Fuel Cell Ambulances (FCEV): Use hydrogen fuel cells as a range extender to charge onboard batteries, providing a significantly higher extended range of up to 300 miles, which is closer to traditional diesel vehicles for demanding shifts.
Refueling and Downtime
Electric Ambulances: Require time plugged into charging infrastructure to replenish batteries, which can take anywhere from tens of minutes on rapid chargers to hours depending on power limits, creating potential downtime during fleet rotations.
Hydrogen Ambulances: Can be refueled with compressed hydrogen in roughly 5 minutes, allowing for immediate back-to-back operational shifts without prolonged downtime.
Energy Efficiency and Onboard Power
Electric Ambulances: Feature high overall powertrain efficiency (converting over 85% of battery energy into motion) and lower moving-part maintenance costs, but heavy medical equipment loads draw heavily on the primary battery and can restrict operational range.
Hydrogen Ambulances: Offer onboard power off-take capabilities directly from the fuel cell system, enabling high-draw medical equipment to run continuously without draining the main drive energy or requiring a separate noisy generator. However, hydrogen systems have lower overall well-to-wheel thermodynamic efficiency and higher complexity.
Infrastructure and Deployment
Electric Ambulances: Benefit from a rapidly expanding public and depot charging grid, with several NHS trusts already successfully deploying electric response and transport vehicles.
Hydrogen Ambulances: Remain in early trial and prototype phases (such as projects via ULEMCo and HVS) because specialized hydrogen refueling stations are scarce and expensive to build.
I suspect that the nature of the terrain in an area, will also affect the type of power selected.
My Sister’s Burst Aorta
This is a personal observation.
- My sister lives near Colchester General Hospital.
- After her aorta burst, she dialled 999 and an ambulance was dispatched.
- The paramedics corrected assessed her problem and didn’t muck around.
- They decided to take her immediately to Papworth Hospital on the other side of East Anglia.
- The road between the two hospitals is dual-carriageway all the way and possibly with a Police escort, they made the trip in time.
- After several months in hospital, she returned home.
- My sister has now fully recovered.
I believe journeys like this, would be faster and more comfortable in a custom-designed high-performance hydrogen fuel-cell ambulance.
It should be noted that the East Anglian Ambulance Service has been known to station ambulances on the bridges over the dual-carriageways to shorten response times to road accidents.
Are Toyota HiLux Pickups Used As Ambulances?
I asked Google AI this question and received this answer.
Yes, Toyota Hilux pickups are used as ambulances, especially in remote, rural, or off-road environments where standard van-based ambulances cannot travel.
Common Configurations
Canopy / Rapid Response Style: The pickup bed is fitted with a secure, weatherproof canopy or Truckman top to carry a single stretcher and essential emergency gear.
Box-Type Modular Body: A fully enclosed, purpose-built medical compartment is mounted directly onto the Hilux chassis, offering a climate-controlled environment and space for advanced life support (ALS) equipment.
Where They Are Used
Off-Road & Disaster Zones: Mountain rescue teams, humanitarian groups, and military field operations rely on the Hilux’s 4×4 capability and high ground clearance.
Specialized Services: Organizations like wildlife hospitals use adapted Hilux trucks as animal ambulances to reach stranded or injured wildlife in rough terrain. International agencies like the UN and WHO also deploy them in regions lacking paved infrastructure.
I would expect that in designing the next generation Toyota HiLux, Toyota have improved on the design for ambulances.
Will A Hydrogen-Powered toyota HiLux Pickup Make A Useful Ambulance?
I asked Google AI this question and received this answer.
A hydrogen-powered Toyota HiLux pickup can make a useful off-road or specialized utility ambulance, but its practical application as a standard emergency vehicle faces major limits.
Advantages for Ambulance Use
Off-road access: The rugged ladder-frame chassis of the HiLux allows access to remote, rugged, or off-road terrain where standard vans or traditional ambulances cannot go.
Quick refueling: Hydrogen fuel cells refuel in about 3 to 5 minutes, offering much faster turnaround times than battery-electric vehicles.
Clean operation: The fuel cell produces zero tailpipe emissions, creating a quiet, exhaust-free environment suitable for patient transport.
Good payload and towing: It targets a towing capacity of around 5,500 pounds (2,500 kg), handling heavy medical gear better than lighter electric alternatives.
Limitations for Ambulance Use
Cabin space: A pickup truck bed and cab offer less enclosed, climate-controlled volume for patients and attending medical staff compared to standard box ambulances or large vans (like the Toyota Hiace).
Infrastructure gaps: Hydrogen fueling stations remain very rare outside select urban or regional pockets, restricting emergency range and operational zones.
Availability: Toyota is targeting production for the hydrogen HiLux by 2028, meaning the vehicle is not yet available for immediate fleet purchase.
I do think though, that it would be very suitable for some specialist operations.
Jim Ratcliffe Mothballs UK Plants Over ‘Ridiculously High Gas Price’
The title of this post, is the same as that of this article in The Times.
These three paragraphs give more details.
Sir Jim Ratcliffe’s Ineos is mothballing three chemical plants in Hull in response to Britain’s “ridiculously high gas price”.
The plants directly employ 245 people producing acetyls, which are used as raw materials for everything from pharmaceuticals to food and military explosives. Ineos said the sites support almost 4,000 jobs in the wider supply chain across Humberside.
Ineos’s Hull acetyls plants “just cannot compete” as gas prices are now 12 times higher in Britain than in the United States, Ratcliffe said. The plants use gas as a feedstock and also burn hydrogen derived from gas as an energy source to power chemical production.
I don’t think, that this story, is as simple as it seems.
Consider.
- Sir Jim Ratcliffe graduated from the University of Birmingham in 1974 with a degree in chemical engineering.
- The plants in Hull make acetyls.
- The acetyl group has a Wikipedia entry.
- From my own experience, the 1970s was an exciting time for chemical engineering.
- ICI were trying to use a process purchased from BASF to make acetylene, which failed miserably, as all the process did was coat Runcorn in soot.
- Did ICI use the acetylene to make acetyls?
- Google AI says you can make acetyl-containing compounds, such as acetic acid and vinyl acetate, starting from acetylene.
- For a time, I shared an office, with a fellow Liverpool University graduate, who was helping to get the ICI plant working.
In the end the ICI plant was dismantled.
Has Sir Jim Ratcliffe A Connection To HiiROC?
I asked Google AI this question and received this reply.
Yes, Sir Jim Ratcliffe has an indirect financial and strategic connection to HiiROC through his petrochemical company, INEOS.
The INEOS Connection: INEOS backed HydrogenOne Capital Growth—a hydrogen-focused investment fund—which made a £10 million equity investment in HiiROC to develop affordable “turquoise hydrogen” (clean hydrogen produced via thermal plasma electrolysis).
Shared Industrial Projects: HiiROC has collaborated on low-carbon hydrogen projects in the Humberside region close to major INEOS operational footprints, connecting clean-tech hydrogen initiatives with heavy UK industrial chemical hubs.
Note.
- The last paragraph, I clipped from The Times mentioned hydrogen.
- The HiiROC process can use any hydrocarbon gas as feedstock and is five times more energy efficient than traditional electrolysis.
- HiiROC is backed technically by the University of Hull.
- The ICI plant produced loads of soot and HiiROC produces carbon black, so I wonder, if the two processes are by any chance related?
It strikes me that some of the various interests have come up with a route to creating acetyls, that is more efficient.
I suspect Sir Jim Ratcliffe will disclose a clever plan at some time.
What Is The Connection Between The University Of Hull And HiiROC?
I asked Google AI this question and received this reply.
The University of Hull and HiiROC have a collaborative partnership focused on developing clean energy technology.
Nature of the ConnectionTechnology
Collaboration: HiiROC worked collaboratively with the University of Hull (leveraging regional programs like those from the university’s Aura Innovation Centre) to help develop and test Thermal Plasma Electrolysis (TPE).
Clean Energy Innovation: This proprietary TPE technology converts biomethane, flare gas, or natural gas into clean “emerald” hydrogen and valuable solid carbon black without greenhouse gas emissions.
By-Product Research: The partnership includes joint efforts to research potential commercial uses for carbon black, the solid carbon by-product created during HiiROC’s hydrogen-generation process.
Regional Growth: HiiROC established its development and testing facilities in Hull to advance this technology, working alongside local academic and business innovation networks tied to the university.
From my experience in the 1960s at ICI Mond Division in Cheshire, I believe that this could be one of the most important research projects in the UK.
Could INEOS Be Going To Collect All Their Flare Gas In Hull?
Consider.
- The HiiROC process can use any hydrocarbon gas as feedstock.
- This would include chemical plant flare gas, biomethane and natural gas.
- The HiiROC process extracts the hydrogen as hydrogen gas.
- The HiiROC process extracts the carbon as carbon black.
I have seven questions.
- Suppose INEOS collected all the flare gas from their chemical plants in Hull, could they use this as feedstock in a HiiROC process to create hydrogen efficiently?
- Could they collect biomethane from Humberside and mix this with the flare gas?
- Could they bring in extra flare gas from chemical plants elsewhere in the UK and Europe using coastal gas tankers or rail tankers?
- Could INEOS use natural gas, if they were short of flare gas and biomethane?
- Could any excess hydrogen be stored in Aldbrough or Rough gas storage?
- Could any excess hydrogen be sold on to other companies?
- Could hydrogen be used to make the acetyls?
I suspect that all questions have an answer in the affirmative.
Conclusion
I feel that Sir Jim Ratcliffe made a very shrewd investment in HiiROC.
Centrica And Return Partner To Scale Battery Flexibility In Germany
The title of this post, is the same as that of this press release from Centrica.
This is the sub-heading.
Centrica Energy and Return have signed long-term Virtual Tolling agreement for 100 MW / 400 MWh of battery storage flexibility in Germany. The contracted capacity is not tied to one dedicated battery project. Instead, it is provided through Return’s Virtual Flexibility Portfolio (VFP), bringing together capacity from Return-owned battery storage assets across Germany
These two paragraphs add more details.
The structure gives Centrica access to Return’s virtual flexibility portfolio, creating greater diversification and resilience, while the underlying capacity remains backed by physical battery energy storage systems (BESS). Rather than relying on one dedicated asset, capacity can be provided from across Return’s broader German battery portfolio.
The deal marks a new partnership between the two companies and brings together complementary strengths: Return provides the physical battery assets and operational expertise, while optimisation will rely on Centrica Energy’s established multi-market optimisation service, with participation across Wholesale Markets and Ancillary Services in Germany to commercialise the flexibility in the market.
It should be noted that this is the third major battery project, where Centrica are optimising a battery in Europe. The others were in Sweden and Finland.
I suspect that Centrica do a good job, when they are asked.
Are Centrica Good At Optimising Grid Batteries?
I asked Google AI this question and received this reply.
Yes, Centrica is considered a strong and established player in grid battery (BESS) optimisation.
Centrica Energy leverages over 15 years of flexible asset trading experience and has actively optimised battery energy storage systems since 2018. They currently manage over 950 MW of grid-scale batteries on contract across the UK and Europe.
Key Strengths in Optimisation
Portfolio Diversification: Unlike smaller or newer software-only optimisers, Centrica balances battery risk alongside a diverse portfolio of renewables, thermal plants, and gas peakers.
Large balance sheets allow them to offer robust financial backing and revenue security (such as multi-year fixed-payment structures) to asset developers.
Verified Performance: Their Centrica Energy BESS Optimisation results—such as strong gross value capture in markets like Belgium—have undergone independent agreed-upon procedures by Deloitte.
Advanced Forecasting: They use proprietary algorithms, meteorology data, and machine learning models to trade dynamically across wholesale, balancing, and ancillary service markets.
They seem to have got all the issues comprehensively covered.
