CO2 to SAF: A One-Step Solution
The title of this post is the same as that of this article on the Chemical Engineer.
This is the sub-heading,
Oxford spinout OXCCU has launched a demonstration plant at London Oxford Airport to trial its one-step process of turning CO2 into sustainable aviation fuel (SAF). Aniqah Majid visited the plant to investigate the benefits of its “novel” catalyst
One word in this sub-heading caught my eye.
When I was a young engineer in the Computer Techniques section in the Engineering Department at ICI Plastics Division, I did a small mathematical modelling project for this chemical engineer, using the section’s PACE 231-R analogue computer.
He was impressed and gave the 23-year-old self some advice. “You should apply that beast to catalysts.”
I have never had the chance to do any mathematically modelling of catalysts either at ICI Plastics or since, but I have invested small amounts of my own money in companies working with advanced catalysts.
So when OXCCU was picked up by one of my Google Alerts, I investigated.
I like what I found.
The three raw ingredients are.
- Green Hydrogen
- Carbon dioxide perhaps captured from a large gas-fired powerstation like those in the cluster at Keadby.
- OXCCU’s ‘novel’ catalyst, which appears to be an iron-based catalyst containing manganese, potassium, and organic fuel compounds.
I also suspect, that the process needs a fair bit of energy. These processes always seem to, in my experience.
This paragraph outlines how sustainable aviation fuel or (SAF) is created directly.
This catalyst reduces CO2 and H2 into CO and H2 via a reverse water gas shift (RWGS) process, and then subsequently turns it into jet fuel and water via Fischer-Tropsch (FT).
The Wikipedia entry for Fischer-Tropsch process has this first paragraph.
The Fischer–Tropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150–300 °C (302–572 °F) and pressures of one to several tens of atmospheres. The Fischer–Tropsch process is an important reaction in both coal liquefaction and gas to liquids technology for producing liquid hydrocarbons.
Note.
- I wouldn’t be surprised that to obtain the carbon monoxide and hydrogen or syngas for the Fischer-Tropsch process, excess hydrogen is used, so the OXCCU process may need a lot of affordable hydrogen, some of which will be converted to water in the RWGS process.
- The high temperatures and pressures for the Fischer-Tropsch process will need a lot of energy, as I predicted earlier.
But I don’t see why it won’t work with the right catalyst.
The Wikipedia entry for the Fischer-Tropsch process also says this.
Fischer–Tropsch process is discussed as a step of producing carbon-neutral liquid hydrocarbon fuels from CO2 and hydrogen.
Three references are given, but none seem to relate to OXCCU.
OXCCU have a web site, with this title.
Jet Fuel From Waste Carbon
And this mission statement underneath.
OXCCU’s mission is to develop the world’s lowest cost, lowest emission pathways to make SAF from waste carbon, enabling people to continue to fly and use hydrocarbon products but with a reduced climate impact.
It looks like they intend to boldly go.
Conclusion
My 23-year-old self may have been given some good advice.
A Trip To The Northumberland Line – 7th November 2025
On Friday, I went to Newcastle to have a look at the new Blyth Bebside station.
I took these pictures between Newcastle and Ashington stations.
Note.
- The impressive slim bridge over the railway at Newsham station. Other places could imitate this. See Bicester Village Station – 28th May 2025.
- The well-filled car park at Newsham station.
- The large amount of new housing.
- The recently-opened Blyth Bebside station.
- The crossing of the River Blyth.
- The under-construction Bedlington station.
- The crossing of the River Wansbeck.
- The single platform Ashington station.
- The train took 36 minutes for the 18 miles.
- According to staff, there is no hostelry close to the station at Ashington, but there is a good gluten-free pub at Seaton Delaval station, that I wrote about in Seaton Delaval Station – 30th March 2025.
I then returned to Blyth Bebside station and took these pictures.
Note.
- Blyth Bebside station is fully step-free.
- There is a sizable car park.
- The wind turbines of Blyth Harbour wind farm can be seen in the distance from the station bridge.
- I estimate the platforms at the station will take a five-car Hitachi Class 802 train or a pair of two-car Class 158 trains.
These are some further thoughts.
The Platforms On The Northumberland Line Are Long
Consider.
- As I said earlier the platforms in the stations appear to be long enough to handle a five-car Hitachi Class 802 train or a pair of two-car Class 158 trains.
- From what some have said about the line, I suspect four-car trains will be needed soon for Newcastle matches.
- But would this be enough, if a local hero like Sting decided to have a Summer concert on the beach?
- Lengthening platforms is often a pain, if you don’t make them long enough.
So were Network Rail just making sure that the track was fit for all eventualities?
Could The Northumberland Line Be Electrified?
These pictures show Platform 1 at Newcastle station, where Northumberland Line trains usually terminate at Newcastle.
Note.
First Bus To Launch 1MW BESS Unit In Hampshire, Aberdeen To Follow
The title of this post, is the same as that of this article on Solar Power Portal.
This is the sub-heading.
Bus operator First Bus has launched its largest energy storage facility yet in Hampshire.
These four paragraphs add more detail.
Located at the company’s Hoeford bus depot, the 1MW battery storage unit, with a 2-hour duration, will begin operations next month.
This will be followed by a bigger battery storage unit with 2MW/4MWh capacity at its depot in Aberdeen, which will begin work by the end of the year.
The FirstGroup division said that it will explore opportunities to build more battery sites across the UK in the future.
The new battery storage facilities will be used to store surplus electricity that will be distributed back to the grid during peak demand and help maintain power supplies. It will also be used to power the company’s more than 1,200 electric bus fleet.
Note.
- Hoeford’s 1MW/2MWh and Aberdeen’s 2MW/4MWh are big batteries.
- They will be installed, where there is a predictable need.
- Google AI says that the First Bus UK News “About Us” page lists 65 depots and outstations.
- I suspect some clever data analysis is being used to optimise the size of a battery to the route structure and number of buses at a depot.
The batteries appear to come from a company called Palmer Energy Technology, who are backed by Barclays, First Bus and the University of Oxford.
This is the Palmer Energy Technology web site, which has these two paragraphs.
Palmer Energy designs and manufactures Battery Energy Storage Systems that apply automotive‑grade principles to stationary applications. PETL specifies premium cells, uses liquid cooling as standard and focuses on intelligent control to drive down operating costs for customers in transport, industry and the grid.
Through our 100% ownership of Brill Power, a University of Oxford spin out, we incorporate Brill Power’s patented active loading BMS technology in all our BESS to increase the lifetime of systems, improve safety and remove geopolitical risks by storing all data on UK servers.
These are my further thoughts.
Electric Bus Charging Puts A Strain On The Grid
A couple of years ago, I had a drink with three bus depot managers in London. They said that some depots were having difficulty getting sufficient power from the grid.
This Google Map shows Hoeford Depot where the first battery has been installed.
Note.
- Hoeford Depot is by the water at Fareham.
- The depot is indicated by the red arrow.
- The depot is surrounded by houses and other businesses.
As an electrical engineer, I would expect that a battery of the right size could sort out any charging problems.
Bus Garage Batteries Could Mop Up Surplus Electricity
Consider.
- I would expect bus garages have a predictable pattern for energy use.
- Buses will often be charged at night, when solar power is low.
- Do bus garages get a cheaper electricity rate at night?
- There will be times, when bus garages can accept excess energy from the grid and store it until they need it.
- This will mean that wind turbines won’t have to be turned off so often.
Palmer’s batteries installed in a bus garage seem to be a simple way to increase renewable energy efficiency and possibly reduce the cost of battery charging.
Would A Bank Finance The Batteries?
I am not a banker or an accountant, but I have worked with some of the very best. One banker, who sadly has now passed on, would have surely backed this company if the technology and the forecasts stacked up, just as he backed the company, that I helped to start.
It does look as if Barclays are backing the company.
Managing Earthworks In A Changing Environment
This image shows the train derailment at Shap at 06:10 on Monday.
The BBC and others were talking about the cause of the derailment being a landslide.
So it was perhaps appropriate that the latest edition of Rail Engineer had a sponsorsed feature with a title of Managing Earthworks In A Changing Environment.
It is well-worth a full read.
What Happened To The Toyota Hydrogen-Powered HiLux?
I wrote about this vehicle in Toyota Unveils Prototype Hydrogen Fuel Cell Hilux, but I’ve not heard any more.
So I asked Google AI, the question in the title of this post and received this reply.
The Toyota hydrogen-powered Hilux is currently in the demonstration and evaluation phase and has not been officially confirmed for mass production. Ten prototypes were built in the UK and are undergoing testing, with some being used for customer and media demonstrations at events like the Paris Olympics. Toyota is using this project to gather data, refine its hydrogen technology, and prepare for a future European market that could see the vehicle go on sale around 2028.
A simple Google search produced this YouTube video and this article in the Toyota UK magazine.
I don’t want to drive one, as that would be illegal, but I have just added riding in one of these beasts to my bucket list.
Toyota Have Gone To The Advanced Propulsion Centre For Their Latest Project
In Toyota Leads Multi-Million-Pound Micromobility Research Project, I write about another project, where Toyota have approached the Advanced Propulsion Centre for funding and technical help. So the Advanced Propulsion Centre must be doing something right, to attract another project from Toyota.
In CoacH2 – The Next Generation Coach, I write about how the Advanced Propulsion Centre are helping to develop the powertrain for Wrightbus’s upcoming hydrogen-powered coach.
It certainly looks like the Advanced Propulsion Centre are in the middle of the net-zero transport revolution.
Toyota Leads Multi-Million-Pound Micromobility Research Project
The title of this post, is the same as that of this news item from the Advanced Propulsion Centre.
These five paragraphs introduce the project.
he Advanced Propulsion Centre UK (APC) has announced the latest project funded through the UK Government’s DRIVE35 Collaborate programme.
Toyota will lead a consortium to research and develop a new lightweight battery electric vehicle in Derbyshire.
The project aims to meet the evolving needs of urban populations while accelerating the shift to zero tailpipe emission transport by validating a novel, lightweight battery electric vehicle (BEV) in the L6e category.
Underlining Toyota’s commitment to investing in the UK’s R&D capabilities, it will be manufactured at Toyota Manufacturing UK’s (TMUK) Burnaston site.
The vehicle addresses the growing demand for sustainable micro-mobility solutions and includes an integrated solar roof, increased connectivity, and lightweight sustainable materials supporting recovery and recycling.
Note.
- The vehicle will be light in weight.
- Toyota is investing in UK R & D.
- The vehicle will be built in Derbyshire at Burnaston.
I asked Google AI, what is an L6e Car and received this reply.
An L6e car is a light quadricycle in the EU vehicle classification system, defined as a light, four-wheeled vehicle with a maximum speed of 45 kph}) (28 mph)) and an unladen mass of no more than 425 kg. (excluding batteries for electric versions). It can be powered by small internal combustion engines or electric motors, and vehicles in this category are often used for urban commuting or small delivery tasks.
Note.
- Sir Alec Issigonis’s famous ADO15 Mini, which was launched in 1962, weighed 580 Kg, seated four and had an initial top speed of 75 mph.
- Sir Alec also designed racing cars and high performance Mini Coopers.
- Another partner in the project specialises in urban delivery vehicles.
I always wonder what sort of electric vehicle, the great car designer would have designed.
These are some further thoughts.
Do Toyota Build Microcars In Japan?
I asked Google AI, the question in the title of this section and received this answer.
Yes, Toyota builds microcars in Japan, and the Toyota C+pod is one example. While Toyota previously focused on larger vehicles, it now manufactures ultra-compact electric vehicles like the C+pod for the Japanese market to meet customer demand for small city cars.
The Toyota C+Pod has this Wikipedia entry, which gives these details.
- Two seats.
- 9.2 KW electric motor.
- 670-690 Kg weight.
- 37 mph.
- 93 mile range.
- The car has air conditioning, air-bags and heated seats.
The number of seats, speed and range would appear to be ideal for a city-car.
Could The Vehicle Be Hydrogen Powered?
I asked Google AI, if small lightweight hydrogen fuel cells exist and received this answer.
Yes, small, lightweight hydrogen fuel cells do exist and are commercially available for various applications, ranging from educational kits to power sources for drones and portable electronics.
I wouldn’t be surprised if the project needed a hydrogen fuel cell of a particular weight, size and power, someone could built it, by scaling an existing design.
Could The Vehicles Be Self Driving?
Not probably now, but as the technology gets more sophisticated, I suspect that it will happen.
Could The Vehicles Replace The Invacar?
This article in The Times is entitled Bring Back Three-Wheeled Cars For Disabled Drivers, Reform Urges.
I would expect that, if Toyota, the Advanced Propulsion Centre and their partners did a comprehensive job, then Toyota’s new car could serve the same purpose as an Invacar, much better in a zero-carbon manner.
There Is This Video Of A Toyota C-Pod.
Conclusion
I believe this project could come up with something special.
Beaulieu Park Station – 30th October 2025
I went to Beaulieu Park station this morning and took these pictures.
Note.
FIRST TO THE FUTURE: Lumo Owner Bids To Turbo-Charge UK Rail With New Routes
The title of this post, is the same as that of this press release from First Group.
These first three paragraphs introduce FirstGroup’s application for the first phase of three separate applications to the Office of Rail and Road (ORR) for new and extended open access rail services.
FirstGroup plc plans to expand its open access rail operations through its successful Lumo business, boosting connectivity, improving UK productivity and passenger choice across the UK.
The expansion aims to replicate the success of Lumo’s Edinburgh to London service in driving material growth on the East Coast Main Line. Lumo operates without government subsidy and contributes more per train mile to infrastructure investment than any other long-distance operator – delivering growth on the railway and connectivity to local communities, at a substantial benefit to the taxpayer.
FirstGroup has submitted the first phase of three separate applications to the Office of Rail and Road (ORR) for new and extended open access rail services, which are described in these bullet points.
- A revised application to run new services between Rochdale and London Euston via Manchester Victoria from December 2028;
- An extension to Lumo’s current Stirling to London Euston track access agreement to operate services beyond 2030;
- A new route between Cardiff and York via Birmingham, Derby, and Sheffield from December 2028; and
- Purchase of new trains meaning continued investment in UK manufacturing of c.£300 million, and long-term jobs.
This paragraph from the press release describes the philosophy of the rolling stock.
Should these applications be successful, FirstGroup will make use of its option to commit further investment in new Hitachi trains built in County Durham. This investment will include five battery electric trains for the Stirling route and three battery electric trains for Rochdale, supporting jobs at Hitachi’s Newton Aycliffe plant. For the services between Cardiff and York, it will deploy refurbished Class 222s.
Note.
- The Class 222 trains will run the Euston and Stirling service until the future Hitachi trains are delivered in 2028.
- The Class 222 trains will run the Cardiff and York service from 2028.
- The Class 222 trains have a maximum speed of 125 mph
- Avanti West Coast’s Class 390 trains have a maximum speed of 125 mph.
- Avanti West Coast’s Class 805 trains have a maximum speed of 125 mph on electrification.
- Avanti West Coast’s Class 807 trains have a maximum speed of 125 mph.
- Grand Central Trains’s future Hitachi trains have a maximum speed of 125 mph.
- Hull Trains’s Class 802 trains have a maximum speed of 125 mph.
- Lumo’s current Class 803 trains have a maximum speed of 125 mph.
- LNER’s current Class 800 and 801 trains have a maximum speed of 125 mph.
- LNER’s current InterCity 225 trains have a maximum speed of 125 mph.
- LNER’s future Class 897 trains have a maximum speed of 125 mph.
- All of the trains, with the exception of the Class 222 trains are electric and have been designed for 140 mph running and can do this if there is appropriate 140 mph signalling.
If the Class 222 trains don’t run on the East and West Coast Main Lines, then these lines could introduce 140 mph running in stages to speed up rail travel between London and the North of England and Scotland.
Rochdale And London
These three paragraphs from the press release describe the proposed Rochdale and London service.
The new Lumo service will operate the first direct service since 2000 between Rochdale and London. Services will call at Manchester Victoria, Eccles, Newton-le-Willows and Warrington Bank Quay. Eccles station connects other parts of the city of Salford, including the fast-growing MediaCity area, via the nearby interchange with Metrolink. Services to Newton-le-Willows will deliver greater rail connectivity for St Helens.
There will be three new return services on weekdays and Sundays, and four return services on Saturdays, which will provide 1.6 million people in the north-west with a convenient and competitively priced direct rail service to London, encouraging people to switch from cars to train as well as providing additional rail capacity. It will also deliver material economic benefits for the communities along the route, including regeneration areas such as Atom Valley and the Liverpool City Region Freeport scheme.
The application has been revised to address the ORR’s concerns about network capacity set out in its letter of July 2025 rejecting FirstGroup’s original application. Supported by extensive modelling, the company has identified sufficient space on the network to accommodate the proposed services. Services will also make use of the Government’s recent investment in power supply for the West Coast Mainline (WCML).
In FirstGroup’s Lumo Seeks To Launch Rochdale – London Open Access Service, I gave my thoughts for Lumo’s application last year.
Differences between the two applications include.
- The service will be run by Lumo’s standard battery-electric Hitachi trains.
- The original application was for six return journeys per day, whereas the new application is for three return services on weekdays and Sundays, and four return services on Saturdays.
Note.
- The battery-electric trains will be able bridge the 10.4 mile gap between Manchester Victoria and Rochdale, and return after charging on the West Coast Main Line.
- The battery-electric trains could be useful during engineering works or other disruptions.
- The trains would be ready for 140 mph running on the West Coast Main Line, when the digital signalling is installed.
- Is the extra return service on a Saturday to cater for football and rugby fans?
I still feel, that with Lumo’s battery-electric trains one or more services could extend across the Pennines to Hebden Bridge, Bradford Interchange or Leeds. Trains would be recharged for return at Leeds.
Stirling And London
This paragraph from the press release describes the proposed Stirling and London service.
Stirling has a wide catchment area, with an estimated three million people living within an hour’s drive. Extending the current track access agreement for the Stirling route from May 2030 will support the shift from car to rail, and investment in the city, as well as in the service’s intermediate stations which include Larbert, Greenfaulds and Whifflet, thanks to greater connectivity to London. The four return services weekdays and Saturdays, and three on Sundays, on the new route are expected to start early in the company’s 2027 financial year.
In Lumo To Expand Scotland’s Rail Network With New London-Stirling Rail Route From Spring 2026, I gave my thoughts for Lumo’s application in June 2025.
Differences between the two applications include.
- The service will only be run initially by Class 222 trains.
- The service will be run by Lumo’s standard battery-electric Hitachi trains after 2028.
- The original application was for five return journeys per day, whereas the new application is for four return services on weekdays and Saturdays, and three return services on Sundays.
- In the original application, Lumo’s new route was to link London Euston directly to Stirling, also calling at Milton Keynes, Nuneaton, Crewe, Preston, Carlisle, Lockerbie, Motherwell, Whifflet (serving Coatbridge), Greenfaulds (serving Cumbernauld) and Larbert.
Note.
- The battery-electric trains could be useful during engineering works or other disruptions.
- The trains would be ready for 140 mph running on the West Coast Main Line, when the digital signalling is installed.
- Is the extra return service on a Saturday to cater for football and rugby fans?
It should be noted that there are always more return services per day going to Stirling, than Rochdale.
Could The Rochdale and Stirling Services Share A Path?
Consider.
- The two services use the West Coast Main Line South of Warrington Bank Quay station.
- Pairs of Class 803 trains can split and join.
- A pair of Class 803 trains are shorter than an 11-car Class 390 train.
- An 11-car Class 390 train can call in Warrington Bank Quay or Crewe stations.
I believe that the Rochdale and Stiring services could share a path.
- One Weekday service per day would be a single train.
- Going South, the trains would join at Warrington Bank Quay or Crewe stations.
- Going North, the trains would split at Warrington Bank Quay or Crewe stations.
- The pair of trains would share a platform at Euston station.
Operating like this would increase the connectivity and attractiveness of the services, and probably increase the ridership and profitability.
Cardiff And York via Birmingham, Derby And Sheffield
These four paragraphs from the press release describe the proposed Cardiff and York service.
Lumo’s new route between Cardiff and York will join up the entire Great British Railway network, connecting all four main lines from the Great Western Main Line to the East Coast Main Line. The plans will also deliver more capacity and drive passenger demand on a previously underserved corridor.
The application proposes six return services each weekday – a significant increase from the current single weekly service.
Bringing Lumo’s popular low-cost model to the corridor will support local communities between Cardiff, Birmingham, Derby, Sheffield, and York. These cities alone have a combined population of more than 2.5 million people. The new services will give local communities access to jobs and services along the route, in support of significant investment that has already been committed by the Government and private sector. This investment includes the Cardiff Capital Regional Investment Zone, the £140million proposed refurbishment at Cardiff Central station, the West Midlands Investment Zone which is expected to create £5.5 billion of growth and 30,000 new jobs, as well as investment plans in Derby, Sheffield and York.
The ORR will now carry out a consultation exercise as well as discuss the applications with Network Rail to secure the required approvals.
Note.
- Only minimal details are given of the route.
- The TransPennine Upgrade will create a new electrified route across the Pennines between York and Huddersfield via Church Fenton, Leeds and Dewsbury.
- The Penistone Line is being upgraded, so that it will handle two trains per hour.
- In the 1980s, the Penistone Line took InterCity 125s to Barnsley.
- The connection with the Penistone Line at Huddersfield has been upgraded.
I am reasonably certain, that FirstGroup intend to route the York and Cardiff service over this partially electrified route.
Sections of the route will be as follows.
- Cardiff and Westerleigh junction – 38 miles – Electrified
- Westerleigh junction and Bromsgrove – 65.2 miles – Not Electrified
- Bromsgrove and Proof House junction – 15 miles – Electrified
- Proof House junction and Derby – 40.6 miles – Not Electrified
- Derby and Sheffield – 36.4 miles – Not Electrified
- Sheffield and Huddersfield – 36.4 miles – Not Electrified
- Huddersfield and York – 41.9 miles – Electrified
There are only two sections of track, that is not electrified.
- Westerleigh junction and Bromsgrove – 65.2 miles
- Proof House junction and Huddersfield – 113.4 miles
Out of a total of 273.5 miles, I believe in a few years, with a small amount of extra electrification or more powerful batteries, Hitachi’s battery-electric high-speed trains will have this route cracked and the Class 222 trains can be sent elsewhere to develop another route.
Rolls-Royce Successfully Tests First Pure Methanol Marine Engine – Milestone For More Climate-Friendly Propulsion Solutions
The title of this post, is the same as that of this press release from Rolls-Royce.
These four bullet points act as sub-headings.
- World first: first high-speed 100 percent methanol engine for ships successfully tested
- Cooperation: Rolls-Royce, Woodward L’Orange and WTZ Roßlau are developing sustainable propulsion technology in the meOHmare research project
- Green methanol: CO2-neutral, clean and safe marine fuel
- Dual-fuel engines as a bridging technology on the road to climate neutrality
Rolls-Royce has successfully tested the world’s first high-speed marine engine powered exclusively by methanol on its test bench in Friedrichshafen. Together with their partners in the meOHmare research project, Rolls-Royce engineers have thus reached an important milestone on the road to climate-neutral and environmentally friendly propulsion solutions for shipping.
“This is a genuine world first,” said Dr. Jörg Stratmann, CEO of Rolls-Royce Power Systems AG. “To date, there is no other high-speed engine in this performance class that runs purely on methanol. We are investing specifically in future technologies in order to open up efficient ways for our customers to reduce CO2 emissions and further expand our leading role in sustainable propulsion systems.”
Rolls-Royce’s goal is to offer customers efficient ways to reduce their CO2 emissions, in-line with the ‘lower carbon’ strategic pillar of its multi-year transformation programme. The project also aligns with the strategic initiative in Power Systems to grow its marine business.
These are some questions.
Why Methanol?
Rolls-Royce answer this question in the press release.
Green methanol is considered one of the most promising alternative fuels for shipping. If it is produced using electricity from renewable energies in a power-to-X process, its operation is CO2-neutral. Compared to other sustainable fuels, methanol is easy to store, biodegradable, and causes significantly fewer pollutants.
“For us, methanol is the fuel of the future in shipping – clean, efficient, and climate-friendly. It burns with significantly lower emissions than fossil fuels and has a high energy density compared to other sustainable energy sources,” said Denise Kurtulus.
Note that Denise Kurtulus is Senior Vice President Global Marine at Rolls-Royce.
Could Methanol-Powered Engines Be Used In Railway Locomotives?
Given, there are hundreds of railway locomotives, that need to be decarbonised, could this be handled by a change of fuel to methanol?
I asked Google AI, the question in the title of this section and received the following answer.
Yes, methanol-powered engines can be used in railway locomotives, but they require a modification like high-pressure direct injection (HPDI) technology to be used in traditional compression ignition (CI) diesel engines. These modified engines typically use methanol as the primary fuel with a small amount of diesel injected to act as a pilot fuel for ignition, a process known as “pilot ignition”. Research and simulations have shown that this approach can achieve performance and thermal efficiencies close to those of standard diesel engines
From the bullet points of this article, it looks like Rolls-Royce have this pilot ignition route covered.
How Easy Is Methanol To Handle?
Google AI gave this answer to the question in the title of this section.
Methanol is not easy to handle safely because it is a highly flammable, toxic liquid that can be absorbed through the skin, inhaled, or ingested. It requires rigorous safety measures, proper personal protective equipment (PPE), and good ventilation to mitigate risks like fire, explosion, and severe health consequences, including blindness or death.
It sounds that it can be a bit tricky, but then I believe with the right training much more dangerous chemicals than methanol can be safety handled.
How Easy Is Green Methanol To Produce?
Google AI gave this answer to the question in the title of this section.
Producing green methanol is not easy; it is currently more expensive and capital-intensive than traditional methods due to high production costs, feedstock constraints, and the need for specialized infrastructure. However, new technologies are making it more feasible, with methods that combine renewable energy with captured carbon dioxide and renewable hydrogen to synthesize methanol.
Production methods certainly appear to be getting better and greener.
Which Companies Produce Methanol In The UK?
Google AI gave this answer to the question in the title of this section.
While there are no major, existing methanol production companies in the UK, Proman is planning to build a green methanol plant in the Scottish Highlands, and other companies like Wood PLC and HyOrc are involved in the engineering and construction of methanol production facilities in the UK. Several UK-based companies also act as distributors or suppliers for products, such as Brenntag, Sunoco (via the Anglo American Oil Company), and JennyChem.
It does appear, that we have the capability to build methanol plants and supply the fuel.
How Is Green Methanol Produced?
Google AI gave this answer to the question in the title of this section.
Green methanol is produced by combining carbon dioxide and hydrogen under heat and pressure, where the hydrogen is created using renewable electricity and the carbon dioxide is captured from sustainable sources like biomass or industrial emissions. Two main pathways exist e-methanol uses green hydrogen and captured carbon dioxide, while biomethanol is made from the gasification of biomass and other organic waste.
Note.
- We are extremely good at producing renewable electricity in the UK.
- In Rolls-Royce To Be A Partner In Zero-Carbon Gas-Fired Power Station In Rhodesia, I discuss how carbon dioxide is captured from a power station in Rhodesia, which is a suburb of Worksop.
In the Rhodesia application, we have a Rolls-Royce mtu engine running with carbon-capture in a zero-carbon manner, producing electricity and food-grade carbon-dioxide, some of which could be used to make methanol to power the Rolls-Royce mtu engines in a marine application.
I am absolutely sure, that if we need green methanol to power ships, railway locomotives and other machines currently powered by large diesel engines, we will find the methods to make it.
What Are The Green Alternatives To Methanol For Ships?
This press release from Centrica is entitled Investment in Grain LNG, and it gives hints as to their plans for the future.
This heading is labelled as one of the key highlights.
Opportunities for efficiencies to create additional near-term value, and future development options including a combined heat and power plant, bunkering, hydrogen and ammonia.
Bunkering is defined in the first three paragraphs of its Wikipedia entry like this.
Bunkering is the supplying of fuel for use by ships (such fuel is referred to as bunker), including the logistics of loading and distributing the fuel among available shipboard tanks. A person dealing in trade of bunker (fuel) is called a bunker trader.
The term bunkering originated in the days of steamships, when coal was stored in bunkers. Nowadays, the term bunker is generally applied to the petroleum products stored in tanks, and bunkering to the practice and business of refueling ships. Bunkering operations take place at seaports and include the storage and provision of the bunker (ship fuels) to vessels.
The Port of Singapore is currently the largest bunkering port in the world. In 2023, Singapore recorded bunker fuel sales volume totaling 51,824,000 tonnes, setting a new industry standard.
Note.
- After Rolls-Royce’s press release, I suspect that methanol should be added to hydrogen and ammonia.
- I don’t think Centrica will be bothered to supply another zero-carbon fuel.
- I can see the Isle of Grain providing a lot of fuel to ships as they pass into London and through the English Channel.
- Centrica have backed HiiROC technology, that makes hydrogen efficiently.
I can see the four fuels ammonia, hydrogen, LNG and methanol competing with each other.
What Are The Green Alternatives To Methanol For Railway Locomotives?
The same fuels will be competing in the market and also Hydrotreated Vegetable Oil (HVO) will be used.
South West Freight Set For Resurgence
The title of this article is the same as that of a feature article in the November Edition of Modern Railways.
One of the topics, the article discusses is lithium mining in Cornwall and its transport from the South West.
I started by asking, Google AI, where lithium is mined in Europe, and received this answer.
Portugal is the only country in the EU currently mining lithium, with the Barroso project being the main focus of future production. However, there are multiple other European countries with significant lithium deposits that are expected to begin mining in the near future, including the Czech Republic, Finland, France, Germany, Spain, and Serbia.
So Cornish lithium will be one of several sources, but surely ideal for UK batteries.
The Modern Railways article has two paragraphs, which describe lithium mining in Cornwall.
But it’s the potential for lithium that may be the most exciting development for rail freight in the region. Cornish Lithium plans to extract it from an open pit at Trelavour, near St Austell, and it is adamant that rail will be vital for its plans to come to fruition. Trelavour is next to the Parkandillack china clay processing plant, and Cornish Lithium plans to use this to bring in essential materials. The volumes are significant – an estimated 180,000 tonnes per year of input are anticipated, most if not all brought in by rail, and the site’s output of around 8,000 tonnes per year could also go by rail. It is hoped the first traffic could run to the site before the end of Control Period 7 in March 2029 in a project that could run for 20 years.
It isn’t just Cornish Lithium seeking to extract this ‘white gold’ from Cornwall. Imerys British Lithium is extracting lithium and producing lithium carbonate, initially at a pilot site in Roche – with the aim of producing around 21,000 tonnes of the material every year for 30 years.
In total the two sites will produce 790,000 tonnes of lithium ores over thirty years, which when averaged is about 72 tonnes per day.
I then asked Google AI, where the lithium will be processed and refined and received this answer.
Lithium from Cornwall will be processed and refined at demonstration and full-scale plants located within the county. Specifically, Cornish Lithium has a demonstration plant in St Dennis and plans to build a full-scale plant there to produce refined lithium hydroxide. Similarly, the British Lithium project, a joint venture with Imerys, is developing a pilot plant and full-scale processing facility in the St Austell area to produce lithium carbonate from granite, says BBC News.
That seems a very comprehensive answer from a computer!
This Google Map shows the area of Cornwall between St. Dennis and St. Austell.
Note.
- St. Austell is in the South-East corner of the map.
- St. Dennis is in the North-West corner of the map.
- Trelavour appears to be just South of St. Dennis.
- In the middle of the map, are the china clay workings.
Although rail is mentioned, it looks like new tracks will have to be laid.
The Modern Railways article says this about using rail.
Should these plans come to fruition, it seems likely rail will play a part in the supply chain. It is not much of an exaggeration to suggest that Cornwall’s lithium deposits offer a generational opportunity for the Duchy, and by extension, for rail freight.
But, if I’m right about the daily amount being around 72 tonnes, then not many trains will be needed.
I have a few further thoughts.
How Much Will The Lithium Be Worth?
I asked Google AI, what is a tonne of lithium metal worth and got this answer.
A tonne of battery-grade lithium metal is worth approximately $77,962 to $80,398 USD, with an average of about $79,180 USD. The price fluctuates significantly based on market conditions, and the value can differ for industrial-grade lithium metal or other lithium compounds like carbonate or hydroxide.
Assuming a price of $80,000, then a day’s production is worth $5,760,000 and a year’s production is worth about $2 billion.
This could be a massive Magic Money Mine for Rachel from Accounts.
Will The Royal Albert Bridge Cope With The Extra Trains?
The Modern Railways article says this.
While there is excitement about the potential from Cornwall’s new and revived minerals industries, there are caveats. One is the train weight limit on the Royal Albert Bridge, Saltash.
Note.
- A five-car Class 802 train weighs 243 tonnes and I’ve seen pairs in Cornwall.
- Other trains may be heavier, but if the lithium refining is done in Cornwall, the lithium trains won’t be too heavy.
As lithium is the lightest metal, is it sensible to perform the processing and refining in Cornwall and leave the unwanted rocks in the Duchy?
