Is A Small Hydrogen Fuel Cell Car Possible?

By small car, I’m meaning something like a Ford Fiesta or a Vauxhall Astra.

Consider.

  • The car will have a power unit of about 100 KW.
  • With four passengers the car would probably weigh about 1500 Kg.

Does A 100 KW Fuel Cell Suitable For A Car Exist?

Intelligent Energy is a British company based in Loughborough.

This is their mission statement on their web site.

Focused on the development of lightweight, high efficiency, hydrogen fuel cell systems.

They also have this product page for a 110 KW fuel cell tailored for automotive use, that weighs 240 Kg.

I suspect if Ford asked for a fuel cell for a hydrogen Fiesta, that Intelligent Energy could provide one.

And I suspect other fuel cell companies could!

How Much Is The Kinetic Energy Of A Car Like This At 100 mph?

Using Omni’s Kinetic Energy Calculator, I get a figure of 422 Wh.

This figure means a battery of perhaps 2 KWh would handle regenerative braking and provide stationary power to get the car started.

Conclusion

From what I have written here, I believe that a hydrogen-powered small car is possible.

Travelling Between London Stations

When I came home from Moorgate this morning, I took my usual 141 bus.

I sat next to a lady about forty, who from her bags looked like she’d just arrived by plane at Gatwick Airport.

After a couple of attempts at conversation, it became obvious, that we didn’t have a common language.

She then produced her phone and indicated that she needed Liverpool Street station.

The 141 bus doesn’t serve Liverpool Street station, but it does serve the Western entrance to Liverpool Street station on  the Elizabeth Line.

It looks to me, that she had been told by a human being, an app or the Internet, that the easiest way from London Bridge bus station to Liverpool Street station was to take the 141 bus from in front of the station and walk across to Liverpool Street station from Moorgate.

But.

  • The Western entrance to Liverpool Street station has no information to indicate, that it gives access to Liverpool Street station.
  • The bus information system indicates Moorgate station.
  • The bus information system does not announce, that for Liverpool Street station, you should alight at Moorgate station.

Perhaps, the bus information system should indicates Moorgate/Liverpool Street station.

Conclusion

How many other transfers between London stations are similarly confusing?

London Bridge And West Croydon By London Overground

This morning, I took a London Overground train between London Bridge and West Croydon stations.

I took these pictures on the route.

Note.

  1. It appears there are no London Overground services running through the Thames Tunnel.
  2. The only service in South London is two trains per hour (tph) between London Bridge and West Croydon stations.
  3. The service seemed to be working well, with no significant delays.
  4. The 10:24 from London Bridge wasn’t very busy, but the return at 11:03 was very crowded and there were no spare seats.

It was certainly better than a Rail Replacement Bus.

These are some further thoughts.

Could West Croydon Station Handle Six Trains Per Hour?

  • West Croydon station has a bay platform 1, that handles all the London Overground services.
  • Typically, a train leaves the platform about 8-9 minutes after it arrives.
  • 6 x 8 is 48 minutes.

It would be tight, but possible.

Before the bay platform was extended, trains used to reverse using a turnback facility to the West of the station, which I described in How Trains Reverse At West Croydon. As this facility appears to be still there, it can probably act as a substitute bay platform for London Overground trains, if the service gets disrupted.

If in the future, it was decided to have a service, which ran say 4 tph to Highbury & Islington station and 2 tph to London Bridge station, I believe this would be possible.

Were Transport for London Training Drivers?

One or possibly both of the trains, that I rode had two drivers.

This is not unusual, but one of the drivers was wearing a Southern Day-glo vest.

So was he instructing the London Overground driver on the route, that the London Overground, doesn’t normally use?

Charging Battery-Electric Trains At London Bridge Station

This Google Map shows the roof of London Bridge station over platforms 10-15.

Note.

  1. The three gaps in the roof are above platforms 10-15.
  2. There are roof supports over the tracks.
  3. Platforms 10 and 11 are at the top, platforms12 and 13 are in the middle and platforms 14 and 15 are at the bottom.

My train used Platform 13 as these pictures show.

Note the roof supports over the tracks.

If the Uckfield or another service needed to be run by battery-electric trains, the trains might need to be charged at London Bridge station, as there may be issues charging using third-rail electrification.

These pictures show rigid overhead conductor rails over the Thameslink platforms at St. Pancras station.

Could rails like these be installed over some or all of the bay platforms to London Bridge station, so that battery-electric trains could be charged?

  • If the battery-electric trains were converted Class 377 or Class 387 trains, these are available as dual-voltage.
  • Uckfield services use Platform 10 at London Bridge station.
  • A round trip to Uckfield station is only 2 x 24.7 miles or 49.4 miles of unelectrified track.
  • Short lengths of 25 KVAC overhead electrification could be installed at Uckfield station and the bay platform at Oxted station if needed.

A dual-voltage battery-electric train with a range of say just over 50 miles could handle Uckfield services.

Thoughts On Alstom At Derby

In the 1970s, I worked at ICI Plastics in Welwyn Garden City in a section called Computer Techniques.

We had a unique mandate from the Divisional Board, that allowed us to stick our nose into anybody’s business.

We certainly weren’t short of computing power, as in addition to the Division’s IBM 360 and dial-up services to GEISco, we had one of the handful of PACE 231R analogue computers in the UK.

Note.

  1. These machines didn’t use many semiconductors.
  2. These beasts could solve up to a hundred simultaneous differential equations and display the answers as graphs on the printers.
  3. Other UK companies and institutions with a PACE 231 R, included BMC, British Rail Research and Cambridge University.
  4. Two were linked together and these did the calculations for the Apollo flights.
  5. Their finest hour would surely have been to use their flexibility and power to bring home the stricken Apollo 13.

I got an interesting introduction to the industrial world in my three years at Welwyn.

One of our problems, was recruiting enough specialist engineers and programming staff.

So in the end, at one of our Monday morning meetings, we wrote our own advert for the Sunday Times.

We got all the staff we needed, but they weren’t the sort of recruits, you’d normally expect in the 1970s. Two were Indian and two were American, but all were recent immigrants. But they were certainly good enough to solve our problems.

I don’t think the Personnel Department were amused at our independent recruitment exercise.

I sometimes wonder if Bombardier (now Alstom) in Derby has a similar recruitment problem.

I am a Control Engineer and all these hybrid systems, that will power the transport of the future, be they trains, planes or automobiles, need lots of engineers with similar skills to myself and those of computer programmers. So do local companies; Rolls-Royce, JCB and Toyota, who probably have their own skill shortages in these areas,  nick the best from Alstom.

It should be noted that in the railway press, it has been said that the Aventras from Derby were late because of software problems.

The Crews Bracing Themselves For A Rise In Electric Car Fires

The title of this post, is the same as that of this article on the BBC.

This is the sub-heading.

Each year, Essex Fire and Rescue Service focuses on one area of “top-up” training for its crews. In recent years, this has included sessions on firefighting at height and managing hazardous materials. This year, a new course is being introduced: How to deal with electric vehicle fires. Why?

These are the first three paragraphs.

Station manager Terry Maher has recently taken on a new role within the fire service.

A hazardous material expert, he is now the service’s lead officer on tackling lithium-ion battery fires.

His new responsibility comes as the number of electric vehicles (EVs) on UK roads hits more than 540,000. And the number is rising fast.

The article certainly worried me.

Most of the views expressed are by a fire officer, who is also a hazard materials expert.

It should be remembered that I have had serious fire training both as a Scout with the London Fire Brigade and a few years later at both Enfield Rolling Mills and at ICI.

These are a few points from the article.

  • Dealing with a petrol or diesel car fire would normally take about 30 minutes. With an EV fire we’re looking at four or five hours or longer, if we’ve used water.
  • As more and more people use electric vehicles we can expect more and more electric vehicle fires.
  • The results of text searches show there were 59 electric vehicle fire references in 2022-23 across England – up from 30 the previous year.

We are dealing with dangerous vehicles and must handle with care.

 

These are my thoughts.

Car Insurance Rates For Electric Vehicles Will Rise

The worse the risk, the more you will have to pay.

A Full Safety Assessment Should Be Done Before Buying An Electric Vehicle

For instance, I have an integral garage in my house and wouldn’t feel safe at night, if an electric car or bicycle was in there on charge.

I certainly wouldn’t buy an electric car with a plastic body. Although I did own a Lotus Elan for over twenty years.

Conclusion

Everybody, who is thinking of buying an electric car or bicycle, should read the BBC article first.

A Trip To Highams Park Station

I went to Highams Park station, as the Internet rumoured, that there could be gluten-free jam doughnuts near the station, at a shop called the Community Larder.

I took these pictures.

Note.

  1. The restored signal box, that I talked about in An Unusual Office Property has been used as a creperie. Unfortunately, it appears to have gone out of business.
  2. The Community Larder had a good selection of cakes, including some that were gluten-free, but no gluten-free jam doughnuts, as they are delivered on Saturdays.
  3. Crossing the roads by the level crossing is a nightmare.
  4. The station needs a step-free bridge.

The 3D Google Map shows the level crossing looking from the East.

Note.

  1. The railway runs North-South through the station, with South to the left.
  2. The signal box is on the South-East corner of the level crossing.
  3. Hale End Road runs East from the level crossing.
  4. The Community Larder is on the South side of Hale End Road.

Sorting the road traffic out will be difficult.

Is This The World’s Smallest Hydrogen Car?

I typed “World’s smallest hydrogen car” into Google and found this web page.

This is the first paragraph of the product description.

The smallest hydrogen fuel-cell car ever commercialized. A small-scale model of a hydrogen fuel-cell application. A funny didactical toy for kids and… adults too!

But it only costs € 99 with the VAT included.

For something more useful, this web page details a ride-on hydrogen fuel-cell lawnmower.

When I find products, like these that can be bought on-line, it strengthens my belief, that at some time in the next few years, someone will demonstrate an Issigonis Mini-sized car that will run on hydrogen.

We must all remember, that engineering is the science of the possible, whereas politics is dreams of the impossible.

East West Rail To Hold Drop-In Events Ahead Of Statutory Consultation

The title of this post is the same as that of this article on RailUK.

These three paragraphs introduce the article.

East West Railway Company (EWR Co) has announced a series of information events in May to help people understand how the formal application process to build the railway works.

Nine information events will be held in May across the whole line of route between Oxford, Milton Keynes, Bedford and Cambridge.

These events are aimed at providing information about the statutory consultation process which will start in June. Details of the proposed design about the route will be shared when the statutory consultation begins.

These are the dates for the information events.

  • Tuesday 7 May – Bedford Rowing Social Club, The Boathouse, Duck Mill Lane, Bedford, MK42 0AX, from 2pm-7pm.
  • Wednesday 8 May – Cutteslowe Pavilion Hall, Cutteslowe Park, Oxford, OX2 8ES, from 2pm-7pm.
  • Thursday 9 May – Weyland Hall, 8-10 North Street, Bicester, OX26 6ND, from 2pm-7pm.
  • Friday 10 May – South Cambridgeshire Hall, Cambourne Business Park, Cambourne, CB23 6EA, from 2pm-7pm.
  • Monday 20 May – Roxton Village Hall, High Street, Roxton, MK44 3EB, from 2pm-7pm.
  • Tuesday 21 May – St Philip’s Church Centre, 185 Mill Road, Cambridge, CB1 3AN, from 2pm-7pm.
  • Wednesday 22 May – Comberton Village Hall, Green End, Comberton, CB23 7DY, from 2pm-7pm.
  • Thursday 23 May – Bletchley Masonic Centre, 263 Queensway, Bletchley, Milton Keynes, MK2 2BZ, from 2pm-7pm.
  • Friday 24 May – Marston Moreteyne Community Centre, Great Linns, Marston Moreteyne, MK4 0DD, from 2pm-7pm.

They would appear to have the area covered.

I shall probably go to the Bedford event, as if I didn’t make it, I could go to another.

Porterbrook Acquires ‘379s’ For Lease To GTR

The title of this post, is the same as that of a small article in the April 2024 Edition of Modern Railways.

This is the first paragraph.

Porterbrook has successfully bid to acquire the fleet of 30 Class 379 Electrostar EMUs from Akiem and will lease them to Govia Thameslink railway, which will use them on Great Northern services.

Note.

  1. Will the Class 379 trains replace all or some of the 39 Class 387 trains currently used by Great Northern?
  2. The Class 379 trains are 25 KVAC overhead only trains, whereas the Class 387 trains are dual-voltage.
  3. If the Class 379 trains are not modified to run on 750 VDC third rail, they will be restricted to Great Northern routes.
  4. It may be a problem, that the Class 379 trains are only 100 mph trains, whereas the Class 387 trains are capable of 110 mph, but I suspect that the Class 379 trains can be upgraded to 110 mph.

It looks to me that it is likely that Govia Thameslink Railway will end up with thirty spare Class 387 trains.

The Wikipedia entry for the Class 387 train, says this about the differences between the two classes of Electrostar.

The Class 387 is a variation of the Class 379 with dual-voltage capability which allows units to run on 750 V DC third rail, as well as use 25 kV AC OLE.

This surely has three main ramifications for Govia Thameslink Railway.

  1. Third rail equipment can probably be fitted to the Class 379 train, if required.
  2. The Class 379 train can probably be uprated to the 110 mph of the Class 387 train.
  3. Retraining the drivers to use the new Class 379 trains, will not be a major exercise.

Govia Thameslink Railway will have the luxury of configuring the trains to run, the services their passengers need and want.

But Govia Thameslink Railway may have a collateral benefit.

In 2015, a Class 379 train was modified to do a trial as a battery-electric multiple unit.

This section in the Wikipedia entry for the Class 379 train, describes the trial.

During 2013, the national infrastructure owning company Network Rail announced that unit 379013 would be used as a testbed for a future Battery-Electric Multiple Unit. Following several months of conversion work and non-service testing, the unit was used to carry passengers for the first time on a Manningtree–Harwich Town service on 12 January 2015. Throughout its five-week trial period, data was gathered to assess its performance; it could reportedly operate for up to an hour on battery power alone, while charging via the pantograph took two hours.

Note.

  1. I feel it would be reasonable to assume, that a Class 387 train could be easily converted to battery electric operation.
  2. I’ve met commuters, who used the prototype every day between Harwich and Manningtree and it gave a good service.
  3. In an hour with stops, a typical Southern commuter service does just 35 miles.

Southern have two routes, where Class 171 diesel trains are still used.

  • Ashford International and Ore – 25.4 miles
  • Hurst Green Junction and Uckfield – 24.7 miles.

A battery-electric train with a range of 30 miles would surely decarbonise these routes.

  • Batteries would be charged, where 750 VDC third-rail electrification is installed.
  • As the Class 387 trains are dual-voltage, a short length of 25 KVAC overhead electrification, could be used to charge the train at Uckfield, if that was to be needed.
  • Alternatively, the Vivarail Fast Charge system could be fitted.

A rough estimate is that ten battery-electric Class 387 trains would be needed to make Govia Thameslink Railway an all-electric railway.

  • The now redundant Class 171 trains could be cascaded to someone, who needs them.
  • The remaining twenty Class 387 trains could be used to replace twenty Class 377 trains, or converted to battery-electric operation and be cascaded to another operator.

Hopefully though, after all of the musical trains, there will be a reliable procedure to convert late model Electrostars into battery-electric trains.

The Definitive Battery-Electric Electrostar

It could have this specification.

  • Based on a Class 377, Class 379 or Class 387 train.
  • Three, four or five cars.
  • I suspect the batteries would be spread around the cars.
  • Dual-voltage or 25 KVAC overhead electrification only.
  • Charging by 25 KVAC overhead electrification or Vivarail/GWR Fast Charge system.

Note.

  1. Battery range appropriate for the route.
  2. In GTR And Porterbrook Unveil £55 million Fleet Modernisation, I talk about an internal refurbishment of GTR’s trains.

It looks to me, that, whatever route Govia Thameslink Railway takes, there could be another twenty refurbished Class 377 or Class 387 trains, that could be available for conversion to four-car battery-electric trains.

Great Western Routes That Could Be Run By Battery-Electric Electrostars

Great Western Railway have 30 Class 387 trains, which are used on Thames Valley services around the London end of the Great Western Main Line.

Routes that could be suitable for Battery-Electric Electrostars include.

  • London Paddington and Didcot Parkway – two trains per hour (tph) – 10 trains
  • London Paddington and Oxford – one tph – 5 trains – 10.5 miles x 2
  • London Paddington and Newbury – one tph – 5 trains
  • Reading and Newbury – one tph – 2 trains
  • Newbury and Bedwyn – one tph – 1 train – 13.3 miles x 2
  • Reading and Basingstoke – two tph – 2 trains – 13.6 miles x 2
  • Reading and Gatwick – two tph – 7 trains – 18.6 miles

Note.

  1. The number of trains is my rough estimate of the number, that would be needed to run each route.
  2. The miles is how much running would be needed on batteries.

My estimated total is 32, but there might be savings from more efficient routes. It looks like a range of around thirty miles would be sufficient.

Conclusion

It looks like after decarbonising Govia Thameslink Railway and the Thames Valley Services of Great Western Railway, there will be twenty high quality Electrostars available to decarbonise other routes.

Stadler’s FLIRT H2 Sets World Record For Hydrogen Powered Train

The title of this post, is the same as that of this article on Rail Technology Magazine.

These three paragraphs introduce the article.

Stadler’s FLIRT H2 has set the Guinness World Record for the longest distance achieved by a hydrogen-powered passenger train without refuelling or recharging.

The record attempt began on the evening of 20th March 2024 at the ENSCO test centre in Pueblo, Colorado, and concluded 46 hours later, with the train completing 2803 kilometres on a single tank filling.

A team of engineers from Stadler and ENSCO drove the vehicle in shifts during the attempt.

The journey is about the same distance as the  crow flies between Edinburgh and Athens.

Stadler have also published this video.

The train appears to be a a Flirt, like Greater Anglia’s Class 755 trains or Transport for Wales’s Class 231 trains, with a power unit in the middle.

Note.

  1. The picture shows a Class 231 train at Cardiff Queen Street station.
  2. A Greater Anglia driver told me, these trains are 125 mph trains.
  3. The Flirt H2 has only two passenger cars, but UK Flirts are have three or four cars.

Perhaps we should buy a few of these trains for long routes like Liverpool and Norwich or Cardiff and Holyhead!

They would surely be ideal for CrossCountry
