Positive Traction Launches 08e – “The Future Of Sustainable Depot Operations”
The title of this post is the same as this article on Rail UK.
This is the first two paragraphs.
Positive Traction has launched the UK’s first re-engineered battery powered shunting locomotive – the 08e.
Free from carbon, NOx and particulate emissions the 08e can fulfil day-to-day operating needs as well as meet the demanding ESG requirement of shareholders, customers, employees and neighbouring communities.
Note.
- 996 Class 08 locomotives were originally produced between 1952 and 1962.
- Around a hundred are still in use on the UK rail network.
- This page on the Positive Traction web site, gives more details.
This could be a sensible use of technology, that carves itself a profitable niche market.
Rolls-Royce Completes Next Step On Its Journey To Decarbonising Business Aviation
The title of this post, is the same as that of this press release from Rolls-Royce.
This is the sub-heading.
Rolls-Royce today announces the successful completion of a series of tests with 100% Sustainable Aviation Fuel (SAF) on its latest generation of business aviation engines, the Pearl 15 and the Pearl 10X. The Pearl 15, the first member of the Pearl engine family, powers Bombardier’s Global 5500 and 6500 aircraft, while the Pearl 10X will power Dassault’s ultra-long-range flagship aircraft, the Falcon 10X.
These are the websites for the three aircraft, with number of passengers, typical cruise speed and range.
- Bombardier Global 5500 – 16 pax – Mach 0.85 – 5900 nm
- Bombardier Global 6500 – 17 pax – Mach 0.85 – 6600 nm
- Dassault Falcon 10X – 19 pax – Mach 0.925 – 7500 nm
This screenshot from the Dassault Falcon 10X web site shows the range from London.
Note that Buenos Aires, the Falkland Islands, Seattle, Seoul and Tokyo are all within range.
I have a few thoughts and observations.
Jet A-1 And 100% SAF
This paragraph from the press release describes how Rolls-Royce are testing the compatibility of Jet A-1 and 100% SAF.
As well as proving compatibility with 100% SAF another target of the test campaign was to run a back-to-back engine test with both Jet A-1 and SAF on the same Pearl 10X engine. The aim was to confirm further improvements in the environmental footprint when switching to SAF. The results from this first back-to-back engine emission test under standard certification conditions provides important correlations for the evaluation of future SAF within our environmental strategy.
Compatibility and back-to-back running is surely very important, as it could be many years before all airports can supply 100 % SAF for visiting jet aircraft.
The Fuels Used In The Tests And The Benefits
These two paragraphs from the press release describes the fuels used and the benefits..
The HEFA (Hydro-processed Esters and Fatty Acids) SAF was produced from waste-based sustainable feedstocks such as used cooking oils and waste fat. This fuel has the potential to significantly reduce net CO2 lifecycle emissions by about 80% compared to conventional jet fuel.
The back-to-back tests conducted with conventional fossil-based fuel and subsequently SAF also confirmed a cleaner combustion of the sustainable fuel, with significantly lower levels of non-volatile particulate matter (nvPM). In combination with the low NOx combustor technology of the Pearl 10X and its additive manufactured combustor tiles a reduction of all emissions was achieved.
Note.
- An eighty percent reduction in lifecycle emissions is not to be sneezed at.
- Cleaner combustion and low NOx emissions are very much bonuses.
- Additive manufacture is better known as 3D-printing and I’m not surprised that Rolls-Royce have embraced the technology.
As an engineer and retired light aircraft pilot, I suspect the tests have met Rolls-Royce’s objectives.
Moving To 100 % SAF
This is the final paragraph of the press release.
The tests demonstrated once again that Rolls-Royce’s current engine portfolio for large civil and business jet applications can operate with 100% SAF, laying the groundwork for moving this type of fuel towards certification. At present, SAF is only certified for blends of up to 50% with conventional jet fuel. By the end of 2023 Rolls-Royce will have proven that all its in-production Trent and business aviation engines are compatible with 100% SAF.
It must be a good selling point for aircraft equipped with Rolls-Royce engines, that the buyer knows that the aircraft can run on 100% SAF.
100 % SAF As An Airline Marketing Tool
It will be interesting to see how airlines use 100% SAF to sell tickets.
As an example, I can see routes like London and Scotland becoming very competitive.
- Avanti West Coast, LNER and Lumo already run all-electric trains to Edinburgh and Glasgow.
- The technology exists to decarbonise trains to Aberdeen and Inverness..
- Other open access operators could well move in to a lucrative market.
- The only way, that the airlines will be able to compete on emissions, would be to move to 100 % SAF.
There must be hundreds of routes like London and Scotland around the world.
100 % SAF And Business Jets
In A Class 319 Train, But Not As We Know It!, I told this tale.
I am reminded of a tale, that I heard from a former GEC manager.
He was involved in selling one of GEC’s Air Traffic Control radars to a Middle Eastern country.
The only working installation of the radar was at Prestwick in Scotland, so he arranged that the dignitaries and the sales team would be flown to Prestwick in GEC’s HS 125 business jet.
As they disembarked at Prestwick and walked to the terminal, the pilot called the GEC Manager over.
The pilot told him “The Scottish Highlands at this time of the year, are one of the most beautiful places in the world! Would you and your guests like a low-level tour on the way back? I can arrange it, if you say so!”
Despite knowing GEC’s draconian attitude to cost control he said yes.
The sale was clinched!
I also remember an article in Flight International about how JCB sold diggers.
- Dealers in a country like Greece would put together a party of prospective customers.
- The customers would then be flown to East Midlands Airport in JCB’s business jet, which is close to the JCB factory at Rocester.
- After a sales demonstration and a tour of the factory they would be flown home.
I once met a lady who had been one of JCB’s cabin staff and she told me it was a very successful sales technique.
I suspect that a business jet running on 100 % SAF would be an even better sales aid.
There are also increasing protests from the greens about business jets, which are seen as producing pollution and are only the toys of the rich and powerful.
Surely, if they were running on 100 % SAF, this would make business jets more acceptable.
100 % SAF And Niche Airlines
In the web site for the Falcon 10X, there is a section called Mission Flexibility, where this is said.
As large as it is, the Falcon 10X can still access typical airports serving business aviation as well as others with challenging approaches. The Falcon 10X will be London City-capable so that it can fly you straight into the heart of global finance. When you’re ready for rest and relaxation, the 10X can whisk you to out-of-the-way corners of the world.
British Airways used to run a service between London City Airport and New York.
- The route used 32-seat Airbus A-318 airliners.
- The flight stopped at Shannon for refuelling.
- It was business class only.
I suspect someone will think about running a similar London City Airport and New York service using a Falcon 10X.
- It has nineteen seats.
- It could do it in one hop.
- It could run on 100 % SAF.
- British Airways must have all the passenger data from the discontinued service.
- A Falcon 10X flies higher than a Boeing 767, Boeing 787 or an Airbus A350.
I have a feeling that flight time would be comparable or better to a flight between Heathrow and New York.
Conclusion
Rolls-Royce would appear to have the right strategy.
If I was going to New York in business class, I’d use it.
Is There A Research Dermatologist Out There?
Consider.
- I have mused about my skin before in My Strange Skin.
- I have been feeling a bit odd because of Babet.
- I have had problems with my left humerus for a few days now and my left hand has not been very co-operative.
- Yesterday, I kept dropping my bag for a start.
- Last night, I needed to go to the loo in the middle of the night. I could hardly walk, because of pain in my right lower leg.
- But I’d forgotten to put the magic Udrate on my feet, before I went to bed. It does seem to stop the water leaking out of my skin.
This picture shows my left hand.
I damaged it badly in a fall, where I took the back off on the edge of a glass door. But with some glue from the Royal London and some TLC from the practice nurse, there are no scars. Surely, it shouldn’t mend that well.
As my ancestors include both Jews and Huguenots, did all those centuries in poor living conditions ghetto-harden my skin?
I hate mysteries and I suspect some of my questions could be answered by an experienced dermatologist.
Cummins Enters Collaboration To Demonstrate Hydrogen Ecosystem
The title of this post, is the same as that of this article from Rental Management.
This is the first three paragraphs.
Cummins®, Columbus, Ind., has signed a Memorandum of Understanding (MoU) with Terex® Advance Mixer, Fort Wayne, Ind., a subsidiary of Terex Corp.; Edge Materials, Cloverdale, Ind.; and PCC Hydrogen, Louisville, Ky., to produce, trial and prove concrete mixer trucks powered by Cummins’ zero-carbon, hydrogen-fueled internal combustion engines.
The project aims to develop a full hydrogen ecosystem together with a hydrogen producer, vehicle manufacturer and end user. It is the first MoU of its kind signed by Cummins.
he four companies will unite their efforts, which will see Cummins’ X15H hydrogen internal combustion engines integrated into the Terex Advance Commander Series of front-discharge concrete mixer trucks. Edge Materials, a ready-mix concrete provider and Terex Advance customers will operate the hydrogen-powered trucks in challenging real-world environments including on construction sites and critical infrastructure projects. PCC Hydrogen, an ultra-low carbon intensity hydrogen producer, will supply the hydrogen fuel as well as stationary storage and dispensing services.
Note.
- The X15H engine also comes in diesel and natural gas versions.
- Cummins also make electrolysers, that can produce hydrogen.
- It looks like the collaboration has all bases covered.
- I suspect similar deals could be done all over the world and with other types of trucks.
It all sounds like a sensible way to go to me.
Silvertown Tunnel: Cracks In Mayoral Policies
The title of this post is the same as that of this article on the BBC.
This is the sub-heading.
It is an infrastructure project that is well-underway with the boring almost completed — but it has a very low profile.
These are the first three paragraphs.
Every step of the Crossrail tunnelling, the media were invited along. Not so with this project.
This is Silvertown Tunnel. It is more than 1km long and will be London’s first road tunnel in over 30 years.
Perhaps one of the reasons it isn’t being pushed publicity-wise, is it is very controversial.
Tom Edwards gives a detailed outline of why the tunnel is controversial.
Under a heading of HGVs Using Bus Lanes, this is said.
Instead of using the Dartford Crossing, larger HGVs will be able to use the tunnel — and its bus lane.
Campaigners said that will mean more HGVs going through Newham and Greenwich.
I’ve also never heard this before.
Sheila Keeble, of the Greenwich Society, said the tunnel “will be magnet for bigger traffic than we’ve got at the moment”.
“One of the issues we have is all the developers are now looking at building distribution centres,” she said.
“At the moment the Blackwall Tunnel protects us from bigger traffic… Silvertown won’t.”
That is all very logical and I suspect we’ll see larger trucks in Hackney and Waltham Forest too!
There was also this bit of nonsense from Transport for London.
TfL says the tunnel will lead to an overall improvement in air quality.
How will all those trucks through the two tunnels reduce pollution?
In 2024, London must vote for a Mayor, who understands hydrogen, mathematics and science!
Low-Carbon Concrete: Separating Greenwash From Reality
The title of this post is the same as that of this article from Construction Management.
This is the sub-heading.
Tales of low-carbon concrete abound, but what exactly does that mean? Kristina Smith looks at what’s in the mix.
This is a paragraph, which shows the scale of the problem.
The oft-quoted statistic is that cement contributes to 7% of the world’s carbon emissions. However, MPA says that in the UK concrete and cement account for just 1.5% of emissions. “From 1990 we have reduced our absolute emissions by 53%, which is faster than the overall economy, mainly by improving energy efficiency at the plants,” says Khosravi.
Noushin Khosravi, is sustainable construction manager at the Concrete Centre, which is part of Mineral Products Association (MPA).
Companies mentioned include.
- Capital Concrete with their Earth Friendly Concrete.
- CarbonCure Technologies, which I wrote about in Mote – World’s First Carbon Removal Plant Converting Wood Waste To Hydrogen.
- Seratech, which I wrote about in Carbon-Neutral Concrete Prototype Wins €100k Architecture Prize For UK Scientists.
I find the Seratech process amazing as it takes carbon dioxide straight from flues to make the cement.
Could we fit a Seratech cement process on the back of a gas-fired power station?
The article is a must-read summary of where the technology is with respect to low-carbon concrete.
Should Hydrogen-Powered Trucks Pay A Lower Charge In The Silvertown And Blackwall Tunnels?
London has a lot of heavy diesel trucks, which include.
Cement mixer trucks.
Large eight-wheeler trucks transporting aggregate, building materials and construction spoil to and from construction sites.
Council refuse trucks.
Skip trucks.
Supermarket delivery trucks.
They are large polluters and the only way they will be made zero-carbon, will be to use hydrogen.
In Cummins Agrees To Integrate Its Hydrogen ICE Technology Into Terex® Advance Trucks, I write about how Cummins and Terex are going to be building hydrogen-powered cement mixers.
This picture shows the baby of the range, which could be ideal for a smaller country like the UK.
Note how it is the other way round to traditional cement mixer trucks.
As companies are now selling low-carbon concrete in the UK, I suspect, it won’t be long before they will be delivering it in a hydrogen-powered zero-carbon truck.
If hydrogen-powered trucks could be given an economic boost, by lowering their charges for the Silvertown And Blackwall Tunnels, this might increase their uptake by owners of large trucks, which would in turn reduce pollution.
But this would need the election of a London Mayor, who had a hydrogen policy other than ignore it and hope it goes away.
Lights And Signs In Old Street Roundabout
London’s slowest construction project seems to have been making a bit of progress as more traffic lights are working and signs have been erected.
Note.
- There’s still a fair bit to do in the middle of the roundabout.
- There is a notice saying it will be finished in early 2024.
- I suspect, that if the bus stops are placed for the benefit of passengers, it will add more passengers to the 141 buses.
But I can’t wait for it to be finished, as it will ease my journeys to the Elizabeth Line. But only because the bus I take gets stuck in all the traffic at the roundabout.
Two days after I took the first pictures, I took these, as I used the Northern Line to go from Old Street station to King’s Cross St. Pancras station.
Note.
- The tunnel and lift need to be completed.
- The walk wasn’t difficult except for the rubbish outside the fast-food shops.
- But then the streets of Islington are paved with rubbish.
- I’m now more convinced that this route opens fully, it’ll increase passengers on the 141 buses.
- But then what does SadIQ Khan and his useful idiots know about mathematical modelling?
Could Train Services At Liverpool Lime Street Station Be Made Carbon-Free?
This map from OpenRailwayMap shows Liverpool Lime Street station.
Note.
- There are ten platforms, which are arranged in two sets of five.
- Electrified tracks are shown in red.
- The lilac track is the loop of the underground Wirral Line.
It would appear that the station is fully electrified.
Services To And From Liverpool Lime Street
These services currently run to and from Liverpool Lime Street station.
- Avanti West Coast – London Euston – 1 tph – Electric
- East Midlands Railway – Norwich – 1 tph – Diesel – Electrified to Liverpool South Parkway – 25.2 miles to electrification at Trafford Park.
- London Northwestern Railway – Birmingham New Street – 1 tph – Electric
- Northern – Blackpool North – 1 tph – Electric
- Northern – Manchester Airport – 1 tph – Electric
- Northern – Manchester Oxford Road – 1 tph – Diesel – Electrified to Liverpool South Parkway – 25.2 miles to electrification at Trafford Park.
- Northern – Warrington Central – 1 tph – Diesel – Electrified to Liverpool South Parkway – 12.7 miles to Warrington Central.
- Northern – Wigan North Western – 2 tph – Electric
- TransPennine Express – Cleethorpes – 1 tph – Electric – Electrified to Liverpool South Parkway – 25.2 miles to electrification at Trafford Park.
- TransPennine Express – Glasgow – 2 tpd – Electric
- TransPennine Express – Hull – 1 tph – Electric
- TransPennine Express – Newcastle – 1 tph – Electric
- Transport for Wales – Chester – 1 tph – Diesel – Electrified to Runcorn – 13.9 miles to Chester.
Note.
- tpd is trains per day
- tph is trains per hour
- There are nine electric services and four diesel services.
It looks to me, that by using battery-electric trains on the four diesel services, Liverpool Lime Street station can be made carbon-free.
Distances on battery power for each service would be as follows.
- East Midlands Railway – Norwich – Both ways – 25.2 miles between Liverpool South Parkway and Trafford Park with charging at both ends.
- Northern – Manchester Oxford Road – Both ways – 25.2 miles between Liverpool South Parkway and Trafford Park with charging at both ends.
- Northern – Warrington Central – Both ways – 12,7 miles between Liverpool South Parkway and Warrington Central with charging between Liverpool Lime Street and Liverpool South Parkway.
- Transport for Wales – Chester – Both ways – 13.9 miles between Runcorn and Chester with charging between Liverpool Lime Street and Runcorn.
Note the flexibility of battery-electric trains allows a variety of charging regimes.
Conclusion
Liverpool Lime Street Station can be made carbon-free
TransPennine Express Releases Blueprint For Improving Service And Fleet Upgrade
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is the sub-heading.
TransPennine Express (TPE), which transferred to the government’s owning group (DOHL) earlier this year, has set out its plans to address many of the issues which have caused problems and disruption for rail customers.
These three paragraphs summarize their plans.
Making Journeys Better: A Prospectus gives clear detail of the issues TPE has faced during the past two years as well as outlining how TPE, under DOHL, will work to make things better, having completed an in-depth review of the business.
Part of the plans involve the operators plans for its new fleet. Its New Trains Programme outlines its long term view for decarbonisation. The report states that TPE will look towards new technology on its fleet to overcome the lack of clarity on the full electrification of the line.
This, it states will help with the cascading and removal of diesel trains faster across its network.
It always looked to me, that TPE under First Group, brought rather a dog’s breakfast of trains, when a unified fleet of Class 802 trains, as per Hull Trains, might have been easier to operate.
- They are already retiring the Class 68 locomotives and their Mark 5 coaches, so surely to decarbonise their services, a number of battery electric high speed trains would be an idea.
- They are already testing Class 802 battery-electric trains for Hitachi and Eversholt Rail.
- I also feel that CAF could offer a suitable battery-electric train, based on the Class 397 train.
TPE say in the example, that they expect a decision later in the month.
TransPennine Express Services And Battery Electric Trains
These are their services and how they would be effected by battery-electric trains.
- Liverpool Lime Street And Newcastle – Fully-electrified after TransPennine Upgrade.
- Liverpool Lime Street And Hull – Fully-electrified after TransPennine Upgrade.. – 42 miles unelectrified – Service could be run by a battery-electric train that charged between Leeds and Micklefield.
- Manchester Airport and Saltburn – Fully-electrified between Manchester Airport and Northallerton after TransPennine Upgrade. – 33.6 miles unelectrified – Service could be run by a battery-electric train that charged between Leeds and Northallerton. Would eliminate overnight noise problems at Redcar.
- Manchester Piccadilly and Newcastle – Fully-electrified after TransPennine Upgrade.
- Manchester Piccadilly and Scarborough – Fully-electrified between Manchester Piccadilly and York after TransPennine Upgrade. – 42.1 miles unelectrified – Service could be run by a battery-electric train that charged between Leeds and York.
- York and Scarborough – Electrified at York – 42.1 miles unelectrified – Service could be run by a battery-electric shuttle train that charged at York.
- Manchester Piccadilly and Huddersfield – Electrified at Manchester Piccadilly – 25.5 miles unelectrified – Service could be run by a battery-electric shuttle train that charged at Manchester Piccadilly.
- Leeds and Huddersfield – Electrified at Leeds – 17.2 miles unelectrified – Service could be run by a battery-electric shuttle train that charged at Leeds.
- Liverpool Lime Street and Cleethorpes – 125,6 miles unelectrified – In Electrification Of The Hope Valley Line, I show how this route can be run by battery-electric trains that charged on existing electrification a short new section of electrification at Cleethorpes.
Note.
- If Manchester Victoria and Huddersfield, is not electrified, battery-electric trains would be able to cross the 25.8 miles of unelectrified track on battery power.
- If Leeds and Huddersfield, is not electrified, battery-electric trains would be able to cross the 17.2 miles of unelectrified track on battery power.
- I am assuming that the TransPennine Upgrade between Manchester and Leeds will be completed, so that between Liverpool Lime Street and Leeds is fully-electrified.
- The only new infrastructure needed would be electrification at Cleethorpes to charge the trains.
All services except for Liverpool Lime Street and Cleethorpes could be run using battery-electric trains with a range on a full battery of at least 100 miles and with no additional electrification.
Electrifying Cleethorpes Station
This Google Map shows Cleethorpes station.
These pictures show the station in June 2023, when it appears to be going through a platform refurbishment.
I don’t think it would be the most difficult station to electrify.
- There are four platforms.
- As the station is likely to get more battery-electric services, including one from King’s Cross, I would suspect that at least three out of the four platforms would be electrified.
- Although, the station is Grade II Listed, there doesn’t appear to be any canopies or important architectural details, that would get in the way of electrification.
Once Cleethorpes station had been successfully electrified, similar installations could be applied at other stations like Saltburn, Scarborough and Skegness.
Conclusion
If TransPennine Express were to buy the right number of battery-electric trains with a hundred mile range, they can decarbonise all their routes in a train factory.
