First Look Inside £2.2bn Silvertown Tunnel
The title of this post, is the same as that of this article on the BBC.
These are the first five paragraphs.
For the first time, Transport for London has invited journalists inside what is one of the most controversial infrastructure projects in the capital.
The Silvertown Tunnel is 1.4km (just under one mile) long and stretches from Silvertown in Newham to the Greenwich Peninsula.
Inside the tunnel, it is extremely wide. A lot bigger than other tunnels like the supersewer or Crossrail. Boring was finished a few weeks ago.
Transport for London (TfL) says the scheme will address queues at the Blackwall Tunnel and reduce pollution. But it has faced fierce opposition from those who think it will do the total opposite and increase pollution and congestion.
And the big question is – even with mitigation – can a road tunnel ever be green?
Note.
- There is a good picture, showing the width of the tunnel.
- It is very wide and can’t be much narrower than the four-lane Queensway Tunnel, which was opened under Mersey in 1934.
These are my thoughts.
I Am Against The Tunnel Being Built
My main reason I am against the Silvertown Tunnel is that Transport for London’s mathematical modelling of and rerouting of buses past my house has been some of the worst I’ve seen. I talk about the bus problems I now have in Is The Nightmare On The Buses Going To Get Worse?
So until the two tunnels; Blackwall and Silvertown are complete and open with tolling, I won’t trust any of Transport for London’s pronouncements.
I also feel that as the Silvertown Tunnel will allow trucks to pass though, there will be times, when they will cut through the East End to get to the Motorways going North.
But now, it’s more or less finished, we will probably need to use it.
How Is The Tunnel Being Paid For?
The Wikipedia entry for the Silvertown Tunnel has a section called Costs, where this is said.
In 2012, the cost was stated to be £600m. A consultation in 2015 stated that the cost of construction was estimated to be £1bn. In March 2020, the cost was increased again, to £1.2 billion. Operation, maintenance and financial costs of the tunnel over 25 years is expected to cost another £1bn.
The £2.2 billion will be repaid by tolls on both tunnels. Effectively, it’s a Private Finance Initiative or PFI.
Can A Road Tunnel Ever Be Green?
This is the question the BBC asked in the last paragraph of my extract.
Although, I am very much against this tunnel, I do believe this tunnel can be green.
- Suppose, the tunnels were made free for zero-carbon vehicles, that were powered by batteries, hydrogen or possibly ammonia.
- This might nudge vehicle owners and operations to go zero-carbon.
This extra number of zero-carbon vehicles would help to clean up London’s air.
I wonder which will be the preferred route for trucks associated with construction to go to and from sites in Central London?
- These trucks are major polluters in Central London.
- There are sensible moves to make construction sites zero-carbon.
If the Silvertown Tunnel didn’t have tolls for zero-carbon trucks, then surely this would nudge, this sizeable group of trucks to go zero-carbon to the benefit of everyone in Central London.
The only problem with making zero-carbon vehicles toll-free, is that it probably ruins the finances of the tunnels, from the point of view of the investors.
Conclusion
I can see lots of conflict starting over the operation of this tunnel.
Why Firms Are Racing To Produce Green Ammonia
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
In the 19th Century, Europeans realised what the Inca had known long before. Bird droppings, or guano, made a fantastic fertiliser.
These are the first three paragraphs.
And so sprang up a gigantic industry dedicated to the harvesting of guano from Latin American bird colonies, where there were huge piles of the stuff.
It was so rich in ammonia, the key ingredient, that a mere whiff could induce coughing and sneezing. Not exactly a pleasant cargo to ferry across the world.
As demand for fertiliser rose in the early 1900s, someone began to think, “Perhaps there’s another way?” That someone was Fritz Haber, a German chemist who, along with Carl Bosch, developed the Haber-Bosch process for synthesising ammonia.
This Wikipedia entry describes the Haber-Bosch process.
This is the first paragraph.
The Haber process, also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. The German chemists Fritz Haber and Carl Bosch developed it in the first decade of the 20th century. The process converts atmospheric nitrogen (N2) to ammonia (NH3) by a reaction with hydrogen (H2) using an iron metal catalyst under high temperatures and pressures. This reaction is slightly exothermic (i.e. it releases energy), meaning that the reaction is favoured at lower temperatures and higher pressures. It decreases entropy, complicating the process. Hydrogen is produced via steam reforming, followed by an iterative closed cycle to react hydrogen with nitrogen to produce ammonia.
These companies are mentioned in the BBC article.
Starfire Energy
This is their web site.
Their home page has a title of Modular, Variable-Rate Ammonia (NH3) Production and this description of their technology.
We are scaling up technologies to make and use carbon-free ammonia fuel. Rapid Ramp is a variable-rate ammonia production process engineered into a modular plant design. Prometheus Fire is a lower temperature, high flow ammonia cracking process that allows ammonia to be used like natural gas, but with no CO2 emissions.
According to the co-founder of the company, Starfire’s process can use intermittent power, like wind and solar.
Could a farmer make their own fertiliser with a containerised system and say a 5MW wind turbine or a small solar farm?
Atmonia
This is their web site.
This description of their process is on their home page.
Atmonia is developing a nitrogen electrolyser with our patented catalyst. The technology uses only air, water and electricity for direct ammonia production. This enables zero carbon ammonia production, when applying renewable electricity.
Could a farmer make their own fertiliser with a containerised system and say a 5MW wind turbine or a small solar farm?
Jupiter Ionics
This is their web site.
Their home page has an endless video and this statement.
We’re commercialising carbon-neutral, electrochemical technology for sustainable agriculture, ammonia-fuelled transport and renewable energy exports.
These three paragraphs in the BBC article, say more about the process used by Jupiter Ionics.
Jupiter Ionics is currently planning to build an ammonia production module on the megawatt scale, which could produce a tonne per day.
Jupiter Ionics’ technology differs from Starfire Energy and Atmonia’s in that it uses lithium as a mediator to break apart nitrogen molecules, which naturally exist as strongly bonded pairs of nitrogen atoms, to form lithium nitride. This then reacts with hydrogen to make the ammonia.
Within the next 12-18 months, Jupiter Ionics aims to scale up its equipment so that it can produce a kilogram of ammonia per day. A grape farmer in the state of Victoria who has solar panels on his land is hoping to trial the system, says Prof MacFarlane.
It appears that Starfire Energy, Atmonia and Jupiter have containerised systems, that can take air, water and electricity and can create sizeable quantities of ammonia for fertiliser or a fuel.
This page on the Ammonia Energy Association web site is entitled Amogy: Ammonia-Powered Tractor, where this is said, alongside a picture of a standard John Deere tractor.
Earlier this month, Amogy demonstrated a new ammonia-powered tractor in Stony Brook, New York. A 100 kW ammonia-to-power system was successfully integrated into a John Deere mid-size standard tractor, which can operate on liquid ammonia fuel for a period of several hours. The tractor conversion demonstration was made possible by significant seed funding secured in late 2021.
The unique system is comprised of a standard liquid-storage tank and highly efficient ammonia-cracking modules integrated into a hybrid fuel cell system, which can provide consistent primary power for several hours per refueling. Therefore, the pioneering vehicle maintains the functionality and duration requirements operators rely on to support farming tasks, which has never been offered with other alternative energy solutions. The ammonia-powered tractor was driven for separate periods, with a refueling session in between. Refueling a tractor with liquid ammonia is fast and simple, similar to gas or diesel refueling.
This is Amogy’s web site.
I can also see a problem, if every farmer of a certain size wants to make their own ammonia for both fertiliser and fuel.
The NIMBYs will have a field day, but at least the countryside’s low-life won’t be nicking your diesel.
Nitricity
The BBC article also talks about Nitricity.
As Josh McEnaney, president and chief executive of Nitricity in the US, explains, spreading ammonia on fields results in greenhouse gas emissions that could be avoided if we took a more direct approach to applying nitrogen, the crucial element that promotes plant growth, to the soil.
His company is developing a system that uses solar-powered plasma cells to fix nitrogen from the air. This is then used to make nitric acid, which can be applied to the soil. Early experiments with tomato plants yielded success and the company is now trialling its technology with suppliers for the US fast food chain Chipotle.
“We don’t require any hydrogen production,” says Dr McEnaney. “We go straight for the fertiliser.”
This is the Nitricity web site.
Two Experts Give Their Views
The BBC article finishes with the views of two experts.
Bill David at the University of Oxford points out that, around the world, there is already lots of infrastructure designed to store and transport ammonia.
He praises large projects for manufacturing ammonia using renewable energy, such as the one in Uzbekistan that will reportedly spew out 454,000 tonnes of ammonia per year with the help of 2.4 gigawatts of wind energy.
While ammonia can be used as a fuel, it can also be cracked to release hydrogen, which may itself be burned as a fuel, points out Lindsey Motlow, senior research associate at Darcy Partners, a technology firm that works with the oil and gas industry.
“We’re seeing real progress in [the] development of ammonia cracking technology,” she says.
Conclusion
According to the BBC article, two percent of the carbon dioxide emitted on the planet comes from the creation of fertiliser.
So it looks like we can either fry or starve, if we don’t address the problem of zero-carbon fertiliser.
But the downside could be every farm having its own wind turbine.
The BBC article and the related web sites are a must-read.
Riding Into the Future: Germany’s Pioneering Hydrogen-Powered Tram Project
The title of this post, is the same as that as this article on bnn Breaking.
This is the sub-heading.
Explore Germany’s groundbreaking project to develop a fuel cell-powered tram, leading the charge in sustainable urban mobility and reimagining the future of public transportation.
These are the first two paragraphs.
In the quiet, industrious corners of Germany, a revolution is unfolding on the tracks of public transportation. A consortium led by Hörmann Vehicle Engineering, alongside partners Heiterblick, Flexiva Automation & Robotik, and Technische Universität Chemnitz, has embarked on a groundbreaking journey to conceptualize, design, and test what could be the world’s next leap in eco-friendly mass transit: a hydrogen-powered tram. The project, aptly named the Hydrogen Tram for Next Generation, merges the realms of innovation, sustainability, and practicality, aiming to redefine urban mobility in ways we’ve only begun to imagine.
The project’s heart beats with a simple yet ambitious goal: to create a fuel cell-powered tram that doesn’t just exist as a prototype but thrives as a model for future public transportation. This initiative isn’t just about building a tram; it’s about reimagining the entire ecosystem surrounding urban mobility. From devising a robust refueling strategy to simulating operations and testing the fuel cell system, the collaborators are leaving no stone unturned. The project, with a generous €8 million budget, is buoyed by support from the federal government’s national hydrogen and fuel cell technology innovation program. This isn’t merely an experiment; it’s a statement of intent by Germany to lead the charge in sustainable transit solutions.
I have a few thoughts.
Chemnitz
These pictures show Chemnitz and its trams.
Note.
- Chemnitz used to be called Karl Marx Stadt.
- Chemnitz has some hybrid trams and tram-trains.
- I described how the Chemnitz trams work in Chemnitz Trams And The Chemnitz Model.
Chemnitz could be a very suitable place to try out the technology.
Hence, the involvement of Chemnitz University in the project doesn’t surprise me.
Tram-Trains
This article on Railway Gazette International, which is entitled Hydrogen Tram Development Project Underway, is also about the same project.
This is the first paragraph.
The Hydrogen Tram for Next Generation project has been launched to develop a fuel cell-powered vehicle which would enable services to be extended into new areas and tram-train routes created without the need for electrification.
It looks like this was added in the translation.
Tram Trains In South London
In The Third-Rail Tram-Train, I postulated using third-rail tram trains to extend the London Tramlink.
Since then Merseyrail have tried to extend, their third-rail electrified network and been told they couldn’t.
I have written these posts about using tram-trains to extend the London Tramlink.
- Could There Be A Tram-Train Connection At Reeve’s Corner?
- Would Third-Rail Tram-Trains Affect The Design Of The Proposed Streatham Interchange Station?
- The Cranleigh Line
- Thoughts On The Sutton Loop Line
- Could Third-Rail Tram-Trains Work The Epsom Downs Branch?
- Could Third-Rail Tram-Trains Be Used To Increase Services In South London?
- Could Beckenham Junction To Birkbeck Be Run Using Third-Rail Tram-Trains?
- Could Tram-Trains Be Used To Advantage In Croydon?
So would a hydrogen-powered tram-train be useful technology to extend the London Tramlink?
It just could be!
Zero-Carbon Between Manchester and Sheffield
This OpenRailwayMap shows the electrification across the Pennines.
Note.
- Red lines are electrified with 25 KVAC overhead.
- Mauve lines are tram lines electrified with 750 VDC overhead.
- The mauve lines in the West are the Manchester Metrolink.
- The mauve lines in the East are the Sheffield Supertram
- Black lines are not electrified.
- Red and black lines are currently being electrified.
- The blue arrow at the bottom of the map indicates Buxton.
- To the North of Buxton, the line linking Manchester and Sheffield is the Hope Valley Line.
- Running North-East from Manchester is the main TransPennine route between Leeds and Manchester via Dewsbury and Huddersfield.
This OpenRailwayMap shows the TransPennine route between Morley and Mossley stations.
Note.
- Colours are as before.
- Morley station is in the North-East corner of the map.
- Huddersfield station is indicated by the blue arrow in the middle of the map.
- Mossley station is in the South-West corner of the map.
In a few years time, there will be 25 KVAC overhead electrification all the way between Leeds and Manchester via Dewsbury and Huddersfield.
This OpenRailwayMap shows the routes around Manchester and Sheffield and the connecting routes between Barnsley, Huddersfield, Manchester and Sheffield.
Note.
- Colours are as before.
- The blue arrow at the bottom of the map indicates Buxton.
- The line to Stocksbridge runs North-West from Sheffield.
- To its East the Penistone Line runs to Huddersfield via Barnsley.
- Manchester has a series of lines to the East that need to be electrified.
How many of these lines could be integrated into the tram systems of Manchester and Sheffield, by the use of hydrogen-powered tram-trains?
Hydrogen-powered tram-trains could share lines with battery-electric trains.
Tram-trains could run from say Cathedral in Sheffield to Piccadilly Gardens in Manchester.
Using self-powered trains would cut the need for expensive infrastructure.
The possibilities are endless and carbon free.
Conclusion
Hydrogen-powered trams and tram-trains could be a valuable tool for decarbonising trams and trains.
Decarbonising The Mid-Cornwall Metro
Although the Mid-Cornwall Metro will probably run initially using what diesel multiple units, after a year or so, the route will be converted to zero-carbon operation.
Newquay To Falmouth Docks
This map shows the Mid-Cornwall Metro.
These are current timings.
- By train can take almost three hours with changes at Par and Truro.
- By car should take 45 minutes to drive the 24.4 miles according to Google.
Note.
- The train timings are for a typical British Rail-era Diesel Multiple Unit on the branches and something smarter between Truro and Par.
- A Day Return ticket would cost £8.90 without a Railcard.
- If there was a through train, that meant you didn’t have to change trains, I estimate that the time could be as low as one hour and 35 minutes.
I feel that most travellers, who had access to a car, would use that to travel between Newquay and Truro.
Newquay To Falmouth Docks By Electric Train
I have ridden in three battery-electric trains.
- Class 379 train – Manningtree and Harwich in passenger service.
- Class 230 train – Vivarail demonstration
- Class 777 train- Liverpool Central and Headbolt Lane in passenger service.
Note.
- All were mouse-quiet.
- There was no detectable difference, when running on battery power in the trains.
It is my view that battery-electric trains are no second-class solution.
Consider.
- Newquay and Par is 20.8 miles.
- Falmouth Docks and Par is 30.8 miles.
- Newquay and Falmouth Docks is 51.6 miles.
- The maximum speed between Par and Newquay is around 30 mph
- The maximum speed between Par and Falmouth Docks is around 50-70 mph
- There are twelve intermediate stations.
- There is a reverse at Par station.
- Charging would be easy to install at Falmouth Docks, Newquay and Par.
- In Par Station – 10th February 2024, I suggested that Par station could be fully-electrified, so that expresses could have a Splash-and-Dash on their way to London and Penzance. If all platforms at Par were electrified the Mid-Cornwall Metro trains could charge from the electrification, as they reversed.
There are two main ways that the Mid-Cornwall Metro might operate.
- There would be chargers at Newquay and Falmouth Docks and trains would shuttle the 51.6 miles between the two stations.
- There would only be charging at Par and trains would after charging at Par go alternatively to Newquay and Falmouth Docks.
The first might need smaller batteries and the second would only need one charger.
Newquay To Falmouth Docks By Hydrogen-Powered Train
There is only one hydrogen-powered train in service and that is the Alstom Coradia iLint, which is running in Germany.
I feel it is very much an interim design, as Alstom has taken a diesel-mechanical Lint train and swapped the diesel for a hydrogen-powered electricity generator and an electric motor.
But Alstom are putting together a hydrogen-powered train based on an Aventra.
Note.
- The train is three cars.
- I would envisage performance of the hydrogen train would be very similar to that of a similar battery-electric train.
- I wouldn’t be surprised that refuelling of the train would not be a problem, as with all the china clay working nearby, there may well be developments to use hydrogen in the industry to decarbonise the mining.
The Mid-Cornwall Metro and Alstom’s Hydrogen Aventra could be ideal for each other.
Conclusion
I believe, that although the Mid-Cornwall Metro will start operation with diesel multiple units, it will be running in a zero-carbon mode within a few years.
ICE Report Shows Majority Open To Net Zero Changes
The title of this post, is the same as that of this article on The Engineer.
This is the sub-heading.
A new report has found that a majority of the UK public is amenable to the behavioural changes needed to hit the country’s net zero targets.
These two paragraphs summarise the findings of the report.
Published by the Institution of Civil Engineers (ICE) and the All-Party Parliamentary Group on Infrastructure (APPGI), the report was based on a survey of 1,000 respondents. It found that 57 per cent were open to change, with 23 per cent described as net zero enthusiasts who were likely to have already altered their behaviours, and 34 per cent wanting change, but feeling they needed further empowerment to achieve it.
However, there is far from universal agreement when it comes to behavioural change around climate action. The report found that 30 per cent of people were ‘reluctant followers’, largely acknowledging that the UK must act on emissions, but not feeling personal responsibility for that action. This segment will likely only change their behaviours if forced to do so or seeing a majority of others doing it first. Finally, 13 per cent of those surveyed were classed as ‘net zero resistors’, people who don’t believe action is necessary and have no intention of doing so.
Summing the figures up gives us.
- Net-Zero Enthusiasts – 23 %
- Wanting Change – 34 %
- Reluctant Followers – 30 %
- Net-Zero Resistors – 13 %
All politicians should be forced to read the full report.
What Would I Need To Do To Achieve a Personal Net-Zero?
My circumstances probably cover a lot of people.
- I am a widow living alone.
- My house is well-insulated with solar-panels on the roof, but heated by gas.
- I don’t have or need a car.
- I do nearly all my shopping by public transport and carry it home.
- When I go away in the UK I use trains.
- If I go to Europe, I either go or come back by train.
- I am coeliac, which means I need to eat some meat to stay healthy.
My largest carbon-emitted is probably my house, but it would be unsuitable for most current solutions.
I would put myself in the Wanting Change group, but I could move to a Net-Zero Enthusiast, if the right technology came along.
- I have seen one bolt-in electric replacement for by boiler and when the right one arrives, I’ll probably fit one.
- An affordable battery to work to with my solar panels and also allow me to use Off Peak electricity would be nice.
- As I’m coeliac, I tend to buy in the same food each week from Marks and Spencer to eat in. I might be able to cut my carbon footprint by getting Ocado to deliver. Especially, as some deliveries seem to be bike.
- If TfL decarbonised the bus, that I use most days to and from Moorgate would that lower my carbon footprint?
I suspect the largest amount of carbon outside of my house’s heating, that I’ll emit, will be tomorrow, when I take a train to Newquay.
How Do We Convert The 13 % Net-Zero Resistors?
The recent protests by French and Belgian farmers indicate, that these farmers are probably in this group. And there are other forthright groups!
The only way, that they’ll be converted, is if technology allows them to earn the same amount of money and have the same outgoings, as they do now!
University Of Leeds Drills Test Boreholes For Geothermal Project To Heat Campus
The title of this post, is the same as that of this article on Ground Engineering.
This is the sub-heading.
A team of researchers at the University of Leeds has started to test the potential to use geothermal energy to heat buildings on campus in a bid to tackle its carbon emissions.
These three paragraphs outline the project.
The project involves drilling eight test boreholes into the ground at several locations on the campus at depths of between 150m to 250m. Work started last Monday (29 January) and will continue until May 2024.
Some of the holes will be water wells at around 50cm in diameter that will look for underground aquifers at the right temperature to use for geothermal heat. Other holes will be monitoring wells at around 15cm in diameter which the team will use to check what impact extracting heat from the ground has on the surrounding areas.
The geothermal project brings together the team responsible for the maintenance and development of the University estate and an academic team which includes professor of geo-energy engineering Fleur Loveridge, research fellow in geosolutions David Barns and lecturer in applied geophysics and structural geology Emma Bramham.
The Wikipedia entry for Geothermal Energy In The United Kingdom, is a very informing and ultimately surprising read.
This is the introductory paragraph.
The potential for exploiting geothermal energy in the United Kingdom on a commercial basis was initially examined by the Department of Energy in the wake of the 1973 oil crisis. Several regions of the country were identified, but interest in developing them was lost as petroleum prices fell. Although the UK is not actively volcanic, a large heat resource is potentially available via shallow geothermal ground source heat pumps, shallow aquifers and deep saline aquifers in the mesozoic basins of the UK. Geothermal energy is plentiful beneath the UK, although it is not readily accessible currently except in specific locations.
With more projects like that at the University of Leeds and the development of better technology, I am confident that over the next few years, we will extract more heat from beneath our feet.
A New Future Beckons For Scotland’s Historic Canals
The title of this post is the same as that as this article on The Herald.
This is the sub-heading.
Scotland’s canals, created for the industrial revolution but in recent times focused more on leisure than industry, are finding a new purpose as a different revolution, this time a green one, gets underway
The article was found by my Google Alert for the Coire Glas project, which is one of the UK’s largest green projects.
The article describes how Scotland’s canals are helping a green revolution and is well worth a read.
Funding Announced For First-In-Class Low-Carbon Installation Vessel For Floating Offshore Wind
The title of this post, is the same as that of this news item from Morek Engineering.
These two paragraphs outline the project.
The UK Government has awarded funding to a consortium led by Morek Engineering to design a new class of low-carbon installation vessel for the floating offshore wind market.
The consortium has won the funding through the UK Government’s Clean Maritime Demonstration Competition based on their proven track record in innovative vessel design and delivery of complex offshore operations. The consortium includes Morek Engineering, Solis Marine Engineering, Tope Ocean, First Marine Solutions and Celtic Sea Power.
Note.
- The design of the ship certainly seems to tick all the boxes.
- This is Morek’s web site.
Because of my experience of writing project management systems, I often wonder, whether some of my discarded ideas of the 1980s could be used in the deployment of floating offshore wind.
Poo power To Heat Homes In West London As Thames Water Continues To Reduce Its Carbon Footprint
The title of this post, is the same as that of this press release from Thames Water.
These are the three bullet points.
- Thames Water unveils its second successful gas-to-grid project.
- Around 4000 homes in West London will be heated using converted sewage sludge from Mogden sewage treatment works starting early this year.
- This initiative is part of Thames Water’s commitment to reduce its carbon emissions across its operations thereby reducing its contribution to the causes of climate change.
These three paragraphs outline the project.
Thames Water has announced sewage sludge will be used to heat homes in West London early this year, after successfully delivering its second gas-to-grid (G2G) project, at its Mogden Sewage Treatment Works (STW).
The success of the gas-to-grid model established at Deephams STW in North London in 2021, where biogas is converted into biomethane to heat homes in Enfield, served as the blueprint for the project at Mogden.
Currently serving over 2 million customers, Mogden is the third largest STW in the UK, and has the potential to reach and supply gas to 4000 homes in West London. This comes as part of the company’s commitment on energy transition, by transforming the way it creates and uses power to reach net zero carbon emissions.
The press release then gives a paragraph of explanation as to how the system works.
A byproduct of the sewage treatment process is sewage sludge, which is then digested to produce BioGas. Mogden STW then generates electricity with this BioGas via Combined Heat and Power (CHP) engines. The Gas-to-Grid plant, which will be managed by gas supplier SGN, intends to take a proportion of this BioGas and to ‘uprate’ it to export quality which is achieved by filtering, scrubbing and then compressing gas so it can be used as fuel for cooking and heating.
This Thames Water graphic illustrates the process.
This press release is not Thames Water’s image from many of its customers.

- Two-car – 601
- Three-car – 249
- Four-car – 135
- Five-car – 176
- Seven-car – 4
- Nine-car – 63
That is a total of 1254 trains that need to be decarbonised by either replacement or modification.
- Some trains are effectively double-counted, as both the current trains and their replacements are included.
- Some trains are planned to be replaced by electric trains.
- Some trains will be passed on.
But there are still a lot of trains to be decarbonised.
I will now look at each group in detail.
BR Second Generation Trains
- Class 150 – 129 x two-car and 6 x three-car.
- Class 153 – 36 x one-car.
- Class 155 – 7 x two-car.
- Class 156 – 109 x two-car.
- Class 158 – 155 x two-car and 15 x three-car.
- Class 159 – 29 x three-car.
- Class 165 – 59 x two-car and 16 x three-car.
- Class 166 – 21 x three-car.
Note.
- The trains have mostly Cummins engines, with some Perkins and a spattering of Rolls-Royce.
- Class 150,153, 155 and 156 trains are 75 mph trains and most of the others are capable of 90 mph.
- Condition of the interiors is variable, with some being excellent and others being terrible.
- There are 36 x one-car, 459 x two-car and 59 x three-car.
- There appears to be no plan to decarbonise these trains.
- Some will be replaced by new CAF diesel trains or new electric trains.
The best use of some of the better trains in this group would be to fill-in until zero-carbon trains are available.
Turbostar Trains
These trains are all Turbostars or their predecessor.
- Class 168 – 9 x two-car, 9 x three-car and 13 x four-car.
- Class 170 – 34 x two-car and 71 x three-car.
- Class 171 – 17 x three-car.
- Class 172 – 24 x two-car and 15 x three-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 100 mph.
- Condition of the interiors is generally good.
- There are 67 x two-car, 112 x three-car and 13 x four-car.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- 168329 has been converted into a diesel-hybrid, by Rolls-Royce mtu.
I feel that one way or another, the trains in this group should be capable of converting to net-zero operation.
Alstom Coradia, Bombardier Voyager and Siemens Desiro Trains
I am putting these trains together, as they are all 100-125 mph long-distance trains, that are not that old.
- Class 175 – 9 x two-car and 15 x three-car.
- Class 180 – 1 x four-car and 12 x five-car.
- Class 185 – 51 x three-car.
- Class 220 – 34 x four-car
- Class 221 – 24 x four-car and 18 x five-cars
- Class 222 – 23 x five-car and 4 x seven-car.
Note.
- The trains all have Cummins engines.
- They are capable of 100 mph or 125 mph.
- Condition of the interiors is generally good.
- There are 9 x two-car, 66 x three-car, 59 x four-car, 53 five-car and 4 x seven-car.
- Cummins engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- In Grand Central DMU To Be Used For Dual-Fuel Trial, I described innovative fuel trails in a Class 180 train.
- I suspect Cummins will be taking an interest.
In Cummins And Leclanché S.A. To Collaborate On Lower-Emissions Solutions For Use In Marine And Rail Applications, I asked this question.
How many of these trains could be converted to hybrid operation, if Cummins and Leclanché were to create their version of the mtu Hybrid PowerPack?
I feel that one way or another, the trains in this group should be capable of converting to net-zero operation.
CAF Civity Trains
These three trains have all been recently introduced
- Class 195 – 25 x two-car and 33 x three-car.
- Class 196 – 12 x two-car and 14 x four-car.
- Class 197 – 51 x two-car and 26 x three-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 100 mph.
- Condition of the interiors is probably as-new!
- There are 88 x two-car, 59 x three-car and 14 x four-car.
- All these trains were ordered between 2016 and 2018.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
I don’t believe that as these trains were only ordered a few years ago, that the trains were bought with the knowledge of a route which would convert these trains to net-zero operation.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing the Rolls-Royce mtu engines with mtu Hybrid PowerPacks.
- Running the trains on sustainable fuel.
The work needed would probably be the same for all trains.
Stadler FLIRT Bi-Mode Trains
- Class 231 – 11 x four-car.
- Class 755 – 14 x three-car and 24 x four-car.
- Class 756 – 7 x three-car and 17 x four-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of between 75 and 100 mph.
- Condition of the interiors is probably as-new!
- There are 21 x three-car and 52 x four-car.
- All these trains were ordered between 2016 and 2018.
- As with other recently ordered trains, I am fairly sure that the Deutz engines will be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
Stadler have designed these trains, so that diesel engines can be replaced by battery packs.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing all or some the Deutz engines with battery packs.
- Running the trains on sustainable fuel.
The work needed would probably be the same for all trains.
Hitachi AT-300 Trains
Only the bi-mode trains are lists.
- Class 800 – 31 x five-car and 49 x nine-car.
- Class 802 – 46 x five-car and 14 x nine-car.
- Class 805 – 13 x five-car.
- Class 810 – 33 x five-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 125 mph.
- Condition of the interiors is probably as-new!
- There are 123 x three-car and 63 x nine-car.
- Most were built after 2016.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- Hitachi are developing battery packs for these trains.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing all or some the Rolls-Royce mtu engines with battery packs.
- Running the trains on sustainable fuel.
The work needed would probably be the same or similar for all trains.
