Daimler Trucks Presents Technology Strategy For Electrification – World Premiere Of Mercedes-Benz Fuel-Cell Concept Truck
This title of this post, is the same as that of this article on the Daimler Global Media Site.
These are the opening bullet points.
- Mercedes-Benz GenH2 Truck, a fuel-cell truck with a range of up to 1,000 kilometers and more for flexible and demanding long-haul transport – customer trials in 2023, start of series production in second half of this decade.
- Mercedes-Benz eActros LongHaul, a battery-electric truck with a range of about 500 kilometers for energy-efficient transport on plannable long-haul routes – projected to be ready for series production in 2024.
- Mercedes-Benz eActros, a battery-electric truck with a range of well over 200 kilometers for heavy urban distribution to go into series production in 2021.
- ePowertrain global platform architecture offers synergies and economies of scale.
Judging by the spelling, this media copy, is from the bad spellers of Trumpland.
It looks to be a case of Daimler have called up the heavy brigade.
The best way to learn more is to search for “Mercedes-Benz GenH2 Truck”
There’s some good YouTube videos.
From this video, I ascertained the following.
- The truck has a stainless steel tank for liquid hydrogen on either side between the front and rear wheels.
- There are two 150 kW fuel cells, which appear to be of an inhouse Mercedes design.
- There is a 70 kWh battery between the two liquid hydrogen tanks low down in the middle of the truck.
- The battery can supply 400 kW, if needed.
This screen capture shows a cutaway from the video.
I am impressed by the design.
- Everything is fitted neatly in the small space.
- The design doesn’t seem to intrude into the load space, so I would assume, it would work with all existing trailers and bodies.
- The battery position must help stability and driveability.
- It looks like a design, that would be friendly to cyclists, as the hydrogen tanks act as a round safety barrier.
I shall look at the operation.
Consider.
- The current Actros trucks have engines with a power of up to 500 HP or 400 kW.
- The 70 kWh battery can provide 400 kW for about 10 minutes.
- Regenerative braking to the battery must be possible.
- There’s probably a well-programmed computer between the driver and the electric transmission.
I wouldn’t be surprised that the truck is more of a battery-hydrogen hybrid, than a pure hydrogen truck.
Suppose, it was hauling a heavy load from Felixstowe to Manchester.
- Will the truck charge the battery before it leaves Felixstowe? It could use the fuel cells or be plugged in to a high-performance charger. 70 kWh, is not the biggest of batteries compared to say those on a train.
- Once on the A45 (Sorry! A14), it would accelerate quickly to the cruising speed, probably using mostly battery power.
- It would then cruise mainly using hydrogen and the fuel cells to the destination. The truck would be optimised for an economic cruise.
- During any deceleration, regenerative braking to the battery would be used.
- Battery power might be called upon on any inclines or after a stop.
Intriguingly, a range of 1000 kilometres or 620 miles would allow many out-and-bank journeys in the UK, France, Germany or Italy to be performed without refuelling.
Leeds, Liverpool, Manchester and Newcastle are all under 300 miles from the Suffolk port.
Conclusion
I used to part-own a company, that financed trucks, moving loads into and out of Felixstowe in the 1980s.
From what I learned then of the heavy truck market, hydrogen-powered heavy trucks are going to be a winner, especially, if most journeys are out-and-back from one end.
Memories Of Althorpe
On The way to Cleethorpes, I passed through Althorpe station.
This Google Map shows the area.
Note.
- The River Trent flowing South to North.
- Keadby power station at the top of the map.
- Althorpe station close to the bridge over the river.
- The village of Althorpe is at the South of the map by the river.
C and myself had friends, who farmed much of the land in the curve of river, South of the railway.
These are a few tales, some might enjoy.
Althorpe And Princess Diana’s Grave
I was once told, that regularly tourists would appear looking for the last resting place of Princess Diana.
Sat-navs may be a wonderful gadget for some, but they do lead those with a certain lack of common sense on wild goose chases.
C And The Tug-Boats
C once spent a night in their farmhouse, which was by the River Trent.
She didn’t sleep well, as tug-boats pulling barges were constantly going past and sounding their sirens. The river was actually above the house, due to the embankments to stop flooding.
Princess Anne And The Centrefold
Our friends’ daughter was a very good rider in eventing and used to supplement her variable income in the sport with modelling. At one point, I used her for some promotional shots for one of my companies.
Some years ago, she was competing at an event in Yorkshire. Coincidentally, this was just after she had appeared as the centrefold in a well-known men’s magazine.
The event was a bit of a nightmare for her, as paparazzi were following her with open copies of the magazine.
At one point, it all got a bit much, so she decided to sneak back to the calm of her horsebox, by a circuitous route.
As she walked back, she encountered Princess Anne, who was also competing and using the same route to avoid the paparazzi.
They talked about the pressures of the paparazzi, who were being a nuisance, with the Princess saying, she approved of my friends’ daughter’s modelling and hoped it continued, as it had taken the pressure off herself.
Flixborough
My friends’ farm was not far from Flixborough, which is infamous for the Flixborough Disaster in 1974, when a chemical plant exploded and killed 28 people and seriously injured a further 36.
My friends also lost several thousand pigs because of the explosion.
Wikipedia says this about the cause of the explosion.
The disaster involved (and may well have been caused by) a hasty modification. There was no on-site senior manager with mechanical engineering expertise (virtually all the plant management had chemical engineering qualifications); mechanical engineering issues with the modification were overlooked by the managers who approved it, nor was the severity of the potential consequences of its failure appreciated.
At the time, I had just left ICI and I was still in contact with my former colleagues.
One told me, that he had met a Senior ICI Engineer, who had been involved with the enquiry into the disaster.
The plant had been a copy of a Dutch plant, that had been built to metric units, which were converted to Imperial to build the Flixborough plant.
As ICI had used metric units since the mid-1950s, there was considerable alarm in the mind of the Senior Engineer, that when the hasty modification was made, someone got mixed up.
Would the Flixborough disaster have happened, if the plant had been built as a copy of the Dutch plant using metric units?
The Big Metro Fleet Upgrade That Could Make It ‘Easy’ To Finally Extend Train Services To New Areas
The title of this post, is the same as that of this article on the Newcastle Chronicle.
This is the first paragraph.
Every train in Metro’s new fleet will be capable of running via an on-board battery, reducing the chance of major shutdowns and making it much cheaper to extend the network.
The fact that it is technically possible, is not a surprise as Stadler’s Class 777 trains for Merseyrail will be using battery power to extend routes. I would be very surprised if the new Tyne and Wear Metro trains and those for Merseyrail, didn’t have a lot of design in common.
But what is surprising, is that the Tyne and Wear Metro’s whole fleet will be fitted with batteries. This must be the first time in the UK, that a whole fleet of trains has been said to have batteries.
The Merseyrail trains will also have a dual voltage capability and will be able to be modified for running on 25 KVAC overhead electrification, as well as 750 VDC third-rail electrification.
Will the Tyne and Wear trains be able to use 25 KVAC electrification? It could be useful in some places on the network and I’m sure, if there was a financial case for a service using existing 25 KVAC electrification, then some trains would be modified accordingly.
A Quick Comparison
This is a quick comparison between Merseyrail’s Class 777 trains and the Tyne and Wear Metro’s new trains.
- Cars – 777 – 4 – T&W – 5
- Operating Speed – 777 – 75 mph – T&W – 50 mph
- Capacity – 484 – T&W – 600
- Capacity Per Car – 121 – T&W – 125
- In Service – 2022 (?) – T&W – 2024
They are not that different and it looks like the Tyne and Wear trains will be built after the Merseyrail trains.
Battery Running
The article says this about running on battery power.
He said the 16km off-wire running would allow for a new loop extending out from South Hylton, through Washington, connecting back to Pelaw.
He added that it would be “easy” to create new connections between existing Metro lines – potentially allowing for a new route through Silverlink and the Cobalt business park in North Tyneside, or a link-up from South Shields towards Sunderland.
Battery power would also solve the problem of running Metro trains on Network Rail lines, which is currently impossible because they operate at different voltages.
Mr Blagburn said: “You could remove the electrification from the complex parts of the route, say over historic structures or through tunnels.
Note.
- The range of sixteen kilometres or ten miles could be very useful.
- The trains appear to be designed to run on Network Rail tracks, as the current trains already do.
- The current trains use the Karlsruhe model to effectively work as tram-trains on shared tracks.
I actually believe that the new Tyne and Wear trains could be modified to run on both 25 KVAC and 750 VDC overhead electrification, as Stadler’s Class 399 tram-trains do in Sheffield.
Conclusion
These trains are using all Stadler’s experience of trains and tram-trains from all over the world.
- They will normally operate using 750 VDC overhead electrification.
- But Stadler have the technology to enable the trains for 25 KVAC overhead electrification, if required.
- They have a range of ten miles on batteries.
- Are the batteries charged by using the energy created by the regenerative braking?
These are not bog-standard trains!
But then neither are the trains built for Greater Anglia by Stadler!
One Side Of A Man’s Kitchen
I’ve now virtually completed one side of my kitchen.
Note.
- The television is on a 270° swivel so it can be watched from outside, when I’m eating or working.
- The worktop will be extended through to continue over storage cupboards and a small deep-freeze on the other side of the hole in the wall.
- The cooker could be replaced by a small AGA-60 City.
- The shelf above the cooker will be moved up a bit and fitted with lights underneath.
- I think a fold-away stool would be better.
- It is currently planned that there will be a low wooden wall between the two sides, that will be topped by a steel beam, so that hot serving dishes can be placed there.
- The flange of the beam could also be used to store condiments, sauces, oils and other things that might be needed both inside and outside the kitchen.
- I haven’t decided where to put the touch-screen pad computer, so I can display my Serial Cooking pages.
- You’ll notice that there isn’t much electrical equipment. The only equipment, that I use is a Delia’s Little Chopper, which I acquired long before she publicised them, a kettle and a microwave .
- You’ll notice the only gas in the kitchen is in the fire extinguisher.
- Gas incidentally, should be banned from inside the inhabited parts of dwellings on health and safety grounds.
Many of the pictures were taken with me sitting on one of my all purpose stools, that I designed over forty years ago and had made by a furniture maker. Incidentally, four were used as saw horses to support the work-top, whilst it was cut to size.
James Cook Station – The Reinvention Of The Halt
Simple stations or halts, were once very common on UK railways. These pictures show James Cook station in Middlesbrough, which is a new small station, that opened in May 2014.
As the trains stopping at the station have conductors to sell tickets, there is no ticket machine, but there is a smart shelter, a help point, a destination board, a step-free bridge and ramps to the single platform.
James Cook station is the first construction in the possible creation of a Tees Valley Metro, which may see other new stations created or old ones reopened.
Surely, some of the ideas used in the design of the single platform James Cook station could be used at several places on the Tees Valley Metro and the wider UK rail network.
Incidentally, is there another station named solely after a person?
Using The Strange Property Of Water To Advantage
Most people, except perhaps those, who live in hot climates, know from their personal experience that ice floats on water. But most people don’t know that water is at its densest at 4°C. So water at this temperature sinks, but it rises at all others.
I once heard somebody use the existence of this property as a reason why God exists. He argued that if it didn’t, then life would have been impossible in water. It was all a bit contrived, but it is still as a strange property.
This morning, I was listening to Wake Up To Money, when a company called SureChill was mentioned. So I looked them up and found that they are using this property to create a new type of refrigerator. This page explains it all. This section describes the solution.
Sure Chill is a brand new kind of cooling system. It doesn’t need a constant power source. In an on-grid situation with intermittent power, it works perfectly well. In an off-grid situation, where a solar panel may be used, a Sure Chill powered refrigerator doesn’t even need a rechargeable battery. It shouldn’t work but it does. And it works beautifully.
Water surrounds a Sure Chill refrigeration compartment. When it has power, the water cools and forms ice above the compartment leaving only water at four degrees cooling the contents. When the power is switched off, the water warms and rises while the ice begins to melt, keeping only four-degree water cooling the contents of the compartment. So it has its own internal and entirely natural energy store that maintains a completely steady temperature. The system can operate like this, without power, for days and weeks.
People think physics is boring. Outside of Metier, I’ve done well in my career and made quite a bit of money by understanding the laws of physics that govern our lives.
My surprise at this idea, is that the technique could have been implemented in a refrigeration system decades ago. Artificial refrigeration was first performed by William Cullen in 1755. My bible; Nelkon amd Parker says that the maximum density of water was first measured by Thomas Charles Hope in 1804.
That is a long time from experimental proof to reality!
Who’d Be A Clothes Retailer?
According to the Daily Mail, winter clothes aren’t selling as it’s still warm. Here’s the first paragraph.
Indian summer hits M&S and Next clothes sales: Stores unable to shift winter boots and coats because of warm October temperatures.
It doesn’t bother me, as I wear almost the same clothes all year round. I’m always in a short-sleeved shirt, with or without a cashmere jumper from M & S. I do swap cords for chinos if it gets too hot, but I rarely wear shorts. And for nearly eight months now, I’ve worn the same lightweight bomber jacket, as it keeps me dry and has the right format of pockets.
If I’m going somewhere smart, I might wear a 25-year-old sports jacket, which is so unstylish that it gets admired all the time. I wore it at CERN.
I am finding that I’m spending less and less money on clothes. I did think that I might get some new expensive Daks cords for the winter, but when I went to try them on, I found that trendy designers had ruined the design. The fastenings were so complicated, if you had got taken short, you wouldn’t have been able to get your trousers down quick enough. So I decided to buy another pair from M & S.
Because of this inability to buy clothes, I now tend to be ruthless in taking unwanted ones to Oxfam and then buy a replacement in probably M & S.
The only thing I spend money on are belts and bags. I’m still searching for a perfect one of the latter. The trouble is they’re not designed by real people.
Riding The Blackpool Trams
I’d never ridden the Blackpool trams until this visit, as often these visits seemed to coincide with their rebuilding.
The trams I rode are modern Flexity 2 units, that are essential for providing a complete service in the 21st Century. Supposedly some of the older trams still run at weekends, but I didn’t see any.
The trams have three problems in my mind.
They should link up with the trains at Blackpool North station. Wikipedia says this.
The tramway is to be extended to Blackpool North railway station after Blackpool Council agreed to provide the remaining funding for the project. [11] A study is currently being undertaken by the council about a further extension to Lytham St Annes.
They need information and maps at the tram stops. As the trams have helpful and chatty conductors, this isn’t as pressing as it could be, but why isn’t there an illustrated map showing the route at each stop?
The tram I rode from the North Pier to the South Pier was crowded to say the least. It strikes me that some serious thinking needs to be done about augmenting the fleet, either by adding more new trams or running the heritage trams more. In an ideal world, where money was no object you’d probably build some innovative new double-deck trams. Come to Blackpool Thomas Heatherwick, Blackpool needs you!
Double-Decker Trains for HS2
According to the Sunday Times today, a design consultancy, Priestmangoode has been asked to make the trains on HS2 as sexy as possible.
I’m all for this and have stated that we should make trains more passenger friendly several times. Here’s a piece where I advocated a better approach to the trains to the West Country and the north of Scotland from London using rebuilt High Speed Diesel Trains.
Transport for London have used this design-led approach on the New Bus for London and I hope it goes well for them, when the bus is introduced next month.
So get the trains right and of course build them in the UK and we might have a railway to be proud of. As someone, who’s travelled from London to Nice on Eurostar and a TGV Duplex, we don’t have much competition from the French. The TGV Duplex may look impressive on the outside, but inside it’s rather cramped and stuffy and the ride is not as good as a High Speed Diesel Train.
Hidden Heroes At The Science Museum
I went to see Hidden Heroes at the Science Museum yesterday. It was quite an interesting little exhibition documenting the stories behind a selection of everyday objects.
As you would expect most of the items shown, had been invented or designed in the major industrial countries like the UK, the United States, Germany, France and Sweden.
But what was surprising was that only one had been designed or invented by a woman. and that was the coffee filter, which was invented by a German housewife called Melitta Bentz. Could it be that she was fed up with her family’s comments on her bad coffee?
In some ways it’s strange, but one of Britain’s most successful and well-known female engineers of the mid-twentieth century, Tilly Shilling, made her name in the field of getting liquids to flow properly. She designed a device, which meant that the Merlin engines in Spitfires and Hurricanes could perform negative-G manoeuvres and thus not be shot down by German fighters.
