Bidders Circle ‘Elvis Airport’ A Decade After The SNP Bought It For £1
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Prestwick has cost taxpayers millions since it was nationalised by the SNP in 2013. A consortium plans a bid, but can the Nats let go of Sturgeon-era stateism?
These are the first two paragraphs.
It was always going to be difficult keeping a lid on the arrival of Elvis Presley at a US military base in Prestwick, Ayrshire. “Where am I?” he asked as he stepped off the plane and into the biting wind that whipped off the Firth of Clyde.
March 3, 1960 was a momentous day for the screaming youngsters who engulfed the American singer as he set foot on British soil for the first and only time. For Presley, it was his last stop on his return from Germany after two years of military service. For Prestwick, it meant being immortalised in British trivia for its brief flirtation with The King.
But now it appears that a consortium has a plan for the airport and has made a bid.
These are my thoughts.
Prestwick Airport
Prestwick Airport, which is 32 miles SouthWest of Glasgow, is an airport that has seen busier times.
This OpenRailwayMap shows the Airport.
Note.
- The airport has two runways at right angles.
- The longer runway is 3,000 metres long.
- The red line is the electrified Ayrshire Coast Line, which runs between Glasgow Central and Ayr.
- There is a station at the airport.
- The black line going across the map is an unelectrified railway line, which eventually leads to the West Coast Main Line.
The airport does have four very useful assets.
- A very long runway capable of handling the largest and heaviest aircraft.
- A railway station.
- Plenty of space.
- The airport has plenty of available landing and take-off slots.
I also suspect that a rail connection could be developed to the West Coast Main Line.
Prestwick As A Cargo Airport
Someone commenting in The Times, suggested that Prestwick could become a cargo airport.
- The main runway could accommodate the largest and heaviest cargo aircraft.
- There is space for stands for large aircraft and warehouses.
- A rail link to the electrified West Coast Main Line could be built.
The airport could have a very high capacity.
A Rail Connection To The West Coast Main Line
This could be very beneficial for air-cargo at Prestwick.
- It would be less than ninety miles to the West Coast Main Line.
- It is only single-track as British Rail removed the second track.
- Cargo Services could be run all over the UK mainland.
- There could even be an airport service from Carlisle.
A zero-carbon rail service for freight, passengers and staff from both Glasgow and Carlisle would enhance the green credentials of the airport.
Where Would Planes Fly?
It looks like a modern freighter aircraft like a Boeing 747-8F could fly at maximum weight to nearly all the USA.
But because Prestwick Airport is further North, It does possibly have a wider range of airports, it can reach.
What Is The Closest Airport In North America?
The two airports on Newfoundland; Gander and St. John’s are probably the two closest being about 2,000 miles from Prestwick.
- Both airports have long runways.
- I suspect a rail terminal could be arranged at the airport to take cargo through the Chunnel to Europe.
- Could USAF Galaxies even be used to bring over American tanks and guns for Ukraine? The range of a Galaxy at maximum weight is 2,600 miles.
- They could be delivered by rail to Ukraine.
I suspect there will be times, where the shorter routes could be useful.
Could Cargo Change Planes At Prestwick?
On some routes like perhaps New York and India, might it be more efficient to change planes at Prestwick.
Could Cargo Planes Refuel At Prestwick?
Planes can only fly so far and is Prestwick in the right place to refuel a long flight?
Prestwick Could Be A Viable Cargo Airport For North America?
I am convinced that Prestwick and North American could be a viable air cargo route.
Zero-Carbon Air Cargo
In the next few years, Scotland will have much more electricity, than it needs, due to all the wind farms in the seas around the country and much of the spare electricity could be converted into hydrogen.
So does a cargo operator plan to run zero-carbon aircraft powered by hydrogen between North America and Prestwick?
- Remember it’s only 2,000 miles between St. John’s or Gander and Prestwick.
- The ideal aircraft to convert to hydrogen, must surely be an Airbus A 380, as there’s a lot of space in the fuselage for a hydrogen tank.
- Cargo could be brought to Prestwick in zero-carbon trains from all over the UK.
Amazon might like the idea of zero-carbon parcels across the pond!
Could An Airbus A380 Be Converted To Hydrogen?
This article on Simple Flying is entitled Airbus Plans A380 Hydrogen Flights In 2026 After Successful Power On Of ZEROe Engine.
The header picture shows a visualisation of an Airbus A 380, with a fifth engine with a propeller mounted on the top of the fuselage. The A 380 will be testing this electric engine, so that it can be fitted in the ZEROe Turboprop sometime around 2030.
This is a visualisation of the ZEROe Turboprop.
Note,
- The hydrogen tank will probably be behind the passenger compartment.
- The A 380, that will be testing the engine is no ordinary A 380. It is the very first and Airbus use it as a flying laboratory for new technology.
- I wouldn’t bet against one of its next jobs, is to test turbofan engines running on hydrogen.
I wouldn’t be surprised that in a few years, Airbus demonstrate an A 380 flying between Europe and North America on hydrogen.
A Zero-Carbon Air Bridge Between Europe And North America
Or does Westjet fancy a zero-carbon shuttle service, which would appeal to the Gretas of this world?
It has been rumoured, that the possible buyers of Prestwick are linked to Westjet.
As soon, as someone announces, a flight like this across the Atlantic, I’ll be signing up!
If the worse should happen, which I think would be unlikely, it would surely be a less painful death, than that of my wife’s from a rare cancer.
Conclusion
There are certainly, possibilities at Prestwick.
Ørsted Secures Exclusive Access To Lower-Emission Steel From Dillinger
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ørsted will be offered the first production of lower-emission steel from German-based Dillinger, subject to availability and commercial terms and conditions. The steel plates are intended to be used for offshore wind monopile foundations in future projects.
These three paragraphs outline the deal.
Under a large-scale supply agreement entered into in 2022, Ørsted will procure significant volumes of regular heavy plate steel from 2024, giving the company access at scale to and visibility of the most crucial raw material in offshore wind while supporting Dillinger to accelerate investments in new lower-emission steel production, according to Ørsted.
The Danish renewable energy giant expects to be able to procure lower-emission steel produced at Dillinger’s facility in Dillingen, Germany, from 2027-2028.
Taking the current technology outlook into account, the reduction of the process-related carbon emissions from production is expected to be around 55-60 per cent compared to conventional heavy plate steel production, Ørsted said.
Increasingly, we’ll see lower emission steel and concrete used for wind turbine foundations.
This press release on the Dillinger web site is entitled Historic Investment For Greater Climate Protection: Supervisory Boards Approve Investment Of EUR 3.5 billion For Green Steel From Saarland.
These are two paragraphs from the press release.
Over the next few years leading up to 2027, in addition to the established blast furnace route, the new production line with an electric arc furnace (EAF) will be built at the Völklingen site and an EAF and direct reduced iron (DRI) plant for the production of sponge iron will be built at the Dillinger plant site. Transformation branding has also been developed to visually represent the transformation: “Pure Steel+”. The message of “Pure Steel+” is that Saarland’s steel industry will retain its long-established global product quality, ability to innovate, and culture, even in the transformation. The “+” refers to the carbon-neutrality of the products.
The availability of green hydrogen at competitive prices is a basic precondition for this ambitious project to succeed, along with prompt funding commitments from Berlin and Brussels. Local production of hydrogen will therefore be established as a first step together with the local energy suppliers, before connecting to the European hydrogen network to enable use of hydrogen to be increased to approx. 80 percent. The Saarland steel industry is thus laying the foundation for a new hydrogen-based value chain in the Saarland, in addition to decarbonizing its own production. In this way, SHS – Stahl-Holding-Saar is supporting Saarland on its path to becoming a model region for transformation.
It sounds to me, that Tata Steel could be doing something similar at Port Talbot.
- Tata want to build an electric arc furnace to replace the blast furnaces.
- There will be plenty of green electricity from the Celtic Sea.
- RWE are planning a very large hydrogen electrolyser in Pembroke.
- Celtic Sea offshore wind developments would probably like a supply of lower emission steel on their door-step.
I would suspect, that Welsh steel produced by an electric arc furnace will match the quality of the German steel, that is made the same way.
Aurizon Secures Funding To Develop Next-Generation Freight Trains Using Renewable Energy
The title of this post, is the same as that of this press release from Aurizon.
These five paragraphs outline the project.
Australia’s largest rail freight company Aurizon, today received a major boost to its program to develop the next generation of Australian freight trains, aiming to replace diesel fuel with renewable energy sources on its locomotive fleet.
Aurizon has secured a $9.4 million grant from the Australian Renewable Energy Agency (ARENA) to develop, test and trial a battery electric tender (BET) to be used in conjunction with a modified locomotive. (refer graphic below).
The tender – essentially a big battery-pack on wheels – will couple with the modified locomotive to operate as a hybrid unit using both diesel and battery-electric power sources. The tender’s battery will also harness re-generative energy captured as the train travels down grades and brakes as part of normal operation.
The ARENA grant represents half of the required funding for the ‘Battery Powered Tender for Heavy Haul Fleet Decarbonisation’ project, with the balance of the investment to be funded by Aurizon. The battery-electric tender and modified locomotive project will be built by Aurizon and technology project partner, Alta Battery Technology (Alta) at a facility in Australia, with design and technology inputs from Alta.
Aurizon appreciates the Federal Government making funding available to support the development of a range of new zero emissions technologies in the transport sector, including technologies that can be developed for application in rail-based freight supply chains that are integral to Australia’s export and domestic industries that rely on transport services.
At a first glance it appears to be suited to Aurizon and its long routes with heavy freight trains across Australia.
These are some more specific thoughts.
Alstom Have Built A Train With a Hydrogen Tender
In From 2025, Nestlé Waters France Will Use The First Hydrogen-Powered Freight Train Through An Innovative Solution Developed by Alstom and ENGIE, I describe a train powered by an electric locomotive with an attached hydrogen power unit.
The Future Of The Class 68 Locomotives
Could these be given a reduced-carbon second life, by developing a specialised tender?
I wrote about this in The Future Of The Class 68 Locomotives.
I suspect Stadler, who seem to be excellent innovators will be watching.
There Seems To Be A Lot Going On In Australia
I have written several posts about decarbonisation of freight trains in Australia.
- BHP To Trial Battery Locos On Pilbara Iron Ore Network
- Battery-Electric Power Rides The Rails
- Wabtec And Roy Hill Unveil The First FLXdrive Battery Locomotive
- Fortescue Unveils World-First Electric Train Using Gravity To Recharge
- BHP Joins The Party On Electric Rail
- Rio Tinto Orders Wabtec FLXdrive Battery Locomotives To Reduce Emissions
The big mining companies certainly seem keen to decarbonise.
Third Rail Or Batteries Could Replace Southern Diesel Trains
The title of this post, is the same as that of this article on Railway Gazette International.
I first wrote about the Uckfield Branch eight years ago, in Future-Proofing The Uckfield Branch.
Since then I have written about this branch several times and I have also read several articles in the railway press.
These are some of my posts.
- Discontinuous Electrification Using IPEMUs – April 30th, 2016
- Will Innovative Electrification Be Used On The Uckfield Line? – August 24th, 1917
- Battery Trains On The Uckfield Branch – August 26th, 2018
- Battery Electrostars And The Uckfield Branch – September 30th, 2019
- Alstom Hydrogen Aventras And The Uckfield Branch – November 12th, 2021
- Electroflex Battery EMU Plan To End Southern Diesel Operation – January 22nd, 2020
- Uckfield Third Rail Is NR Priority – May 2nd, 2022
- Southeastern Keen On Battery EMUs – August 12th. 2023
It is an utter disgrace that no decision has been made in eight years about how to decarbonise to Uckfield.
The Railway Gazette article says this about third-rail electrification.
GTR is one of two operators participating in a Rail Safety & Standards Board project reviewing the safety, legal and regulatory issues around third rail electrification infill projects. This is looking at whole transport system safety, project and economic risks.
Bi-monthly South of England Diesel Replacement Programme meetings are held by DfT, Network Rail and GTR to review progress and options for third rail electrification of the Uckfield line or battery train trials. This includes reviewing the lessons learned from the use of bi-mode trains by GWR and LNER, and the failed attempt to deploy tri-mode Class 769 units on GWR’s North Downs services.
Could it just be that there is such fear that there will be a major incident, where several people are killed, that third-rail electrification is always turned down, by the Office of Road and Rail?
The Railway Gazette article also says this about battery trains, under a heading of Batteries Viable.
In the absence of electrification, GTR says battery powered trains are also a viable option for its diesel routes. Batteries can be charged while trains are running on electrified lines or through a rapid recharging facility at a terminus, although additional infrastructure and electrical upgrades may be needed.
I suspect that after a few teething troubles, Merseyrail would agree.
Hydrogen is also dismissed with this paragraph.
GTR has considered hydrogen but says it can only be considered a net zero-compliant fuel if it is produced from low or zero-carbon energy sources. It is also relatively inefficient with studies indicating an efficiency rate of around 35% to 40%.
It looks to me, that battery-electric trains are a viable solution.
So would it not be a good idea to take the decision to create a battery-electric prototype from a four-car Electrostar or a Class 350 train, so that the final decision can be taken after everybody on the committee has have a ride first?
Better still, why not stage a competition, where manufacturers, leasing companies or remanufacturers can build a four-car train and enter.
Allow the public to ride in them and then see what is best against a range of criteria.
The King could even get involved, as he’s probably one of the few people left, who rode the original British Rail BEMU between Aberdeen and Ballater, to get to Balmoral.
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.
