The Anonymous Widower

Universal Hydrogen CEO Sees Jetmakers Backing New Fuel

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

It is mainly predictions by Paul Eremenko, who is Chief Executive of Universal Hydrogen, about the future of the single-aisle jet airliner market.

I wrote in detail about their technology in Could Universal Hydrogen’s Concept Create A Hydrogen-Powered Single-Aisle Airliner?.

I firmly believe they have a concept that will work and look forward to flying in a hydrogen-powered aircraft using Universal Hydrogen’s technology before the end of the decade.

Could Universal Hydrogen’s Concept Create A Hydrogen-Powered Single-Aisle Airliner?

Universal Hydrogen are making some of what I would consider the right moves.

Hydrogen Supply

Universal Hydrogen have signed a supply contract with Fortescue Future Industries for the supply of green hydrogen.

The deal is described in this press release on the FFI web site, which is entitled FFI And Universal Hydrogen Join Forces To Decarbonise Aviation.

Collaboration With Airbus

There is an article on BusinessWire, which is entitled Universal Hydrogen Announces New Engineering Development Center Located In Toulouse, France, The Heart of European Aviation.

Toulouse is the home of Airbus.

The Capsule Concept

The capsule concept could be universal.

These are widths of various planes and trains.

  • De Havilland Canada Dash 8-400 – 2.52 metres – Internal
  • Airbus ATR 72 – 2.57 metres- Internal
  • Airbus A320neo – 3.7 metres – Internal
  • Boeing 737 – 3.53 metres – Internal
  • Class 800 train – 2.7 metres – External
  • Class 66 locomotive – 2.65 metres – External

I suspect that if the design is correct, then one size of capsule can be made to fit a variety of applications.

Application To Regional Aviation

I discussed this in Flybe Appears To Be On The Way Back.

I believe that De Havilland Canada Dash 8s and Airbus ATR 72s could be converted to hydrogen.

Road Transport

Surely, the capsules would be too big for road transport in the UK and many other countries.

But they would probably be ideal to deliver hydrogen to bus and truck depots and filling stations for hydrogen vehicles. They would just be plugged in and then could start dispensing the fuel.

Decarbonation Of Diesel Locomotives

Consider.

  • The cross-section of a diesel locomotive even in the UK, is larger than that of a regional airliner.
  • Most of the space in the body of a diesel locomotive is taken up by a large diesel engine.
  • Fuel ells or a small gas turbine could be small compared to the diesel engine.
  • Most existing diesel locomotives have electric transmissions.

I believe that many diesel-electric locomotives could be converted to hydrogen power and some could use Universal Hydrogen’s capsules.

Zero-Carbon Backup Generators

Many pieces of important infrastructure, like data centres, hospitals and large railway stations have backup generators.

Universal Hydrogen’s capsules could provide hydrogen for zero-carbon backup generators.

Universal Hydrogen’s Ideas For Single-Aisle Airliners

In the Product page on the Universal Hydrogen web site, there is a section, which is entitled Single Aisle / Narrowbody, where this is the first two sentences.

The majority of aviation emissions are produced by the single aisle (also known as narrowbody) fleet, dominated by the Boeing 737 and Airbus A320 families of aircraft. Both Boeing and Airbus are likely to develop a replacement for these venerable models for entry into service in the mid 2030s.

Alongside the text is this graphic, which compares various airliners.

Universal Hydrogen are proposing that Airbus stretch the A321, so that hydrogen capsules can be fitted in the rear of the fuselage, so that the aircraft has similar proportions to the Boeing 757.

Read the full text on the Product page of the Universal Hydrogen web site.

I can see that if they could prove the concept with the Regional Airliner, they could develop the two concepts shown in the graphic.

Conclusion

This is a simple, but very exciting project.

Is Lumo The Ryanair Of Rail?

Someone had to draw the comparison between Lumo and Ryanair and it was The Times, that used a headline of Lumo, The Ryanair Of Rail, Gets The Green Light On East Coast, for their article about the new London and Edinburgh rail service in their article today.

But how alike are the two business models?

Standard Planes And Trains

The Boeing 737 and the Airbus A 320, as used by Ryanair and easyJet  are the two workhorses of short haul airlines.

It can also be said, that Hitachi’s AT-300 train is becoming the workhorse of long-distance rail services in the UK.

Customised Interiors

Ryanair and easyJet do customise the interiors of their aircraft to a certain extent and from pictures on the Internet Lumo appear to have done the same.

If you look at the widths of the planes and trains on Wikipedia, you find these values.

  • Airbus A 320 – 3.95 metres
  • Boeing 737 – 3.8 metres
  • Class AT-300 train – 2.7 metres

Dividing by the number of seats across, which is six for the planes and four for the train gives these figures.

  • Airbus A 320 – 0.66 metres
  • Boeing 737 – 0.63 metres
  • Class AT-300 train – 0.67 metres

I know there is an aisle down the middle, so let’s say that it is 0.60 metres. This gives these spaces for each seat.

  • Airbus A 320 – 0.56 metres
  • Boeing 737 – 0.53 metres
  • Class AT-300 train – 0.53 metres

I think that is adequate space for a designer to do a good job.

This picture shows the interior of a Great Western Railway Class 802 train, which use a similar body shell to the trains used by Lumo.

Note.

  1. The aisle looks to be similar in width to a seat.
  2. There is a bag shelf above the windows and lots of coat hooks.

As both Lumo and Great Western Railway are both First Group companies, is it likely that the interior dimensions are similar, so that standard trolleys could be used and training could be eased and shared between companies in the group.

This picture shows a trolley fitting in between the tables on a Great Western Railway service.

I suspect, if they design everything together, Lumo could make best use of a narrow aisle to give the seats a bit more width.

This last picture shows TransPennine Express Class 802 train at Willesden Junction station.

Note how the lower part of the side of the train is curved. Is this to get a bit more room for the seat squab?

Passengers Per Metre

This is only a rough calculation and shows typical passengers, fuselage or car length and passengers per metre.

  • Airbus A 320 – 164 passengers – 37.57 metres – 4.4 px/metre
  • Boeing 737 – 160 passengers – 37.0 metres – 4.3 px/metre
  • Class AT-300 train – 96 passengers – 26 metres – 3.7 px/metre

Passenger density in the train is about fourteen percent less.

Toilets

In The Definitive Seating Layout Of Lumo’s Class 803 Trains, I said this.

This article on Economy Class and Beyond is entitled Enter Lumo – The New East Coast Railway Competitor.

It contains a drawing from Lumo,  which shows the layouts of the seats on the train.

    • Coach A – 44 Standard seats – 8 Priority seats – 2 Wheelchair spaces – 2 Tip up seats – Accessible toilet – 56 Total seats
    • Coach B – 84 Standard seats – 12 Priority seats – Bike store – Toilet – 96 Total seats
    • Coach C – 84 Standard seats – 12 Priority seats – 96 Total seats
    • Coach D – 84 Standard seats – 12 Priority seats – Bike store – Toilet – 96 Total seats
    • Coach E – 52 Standard seats – 8 Priority seats – 2 Tip up seats – Accessible toilet – 62 Total seats

Note.

    1. This is a total of 406 seats.
    2. Judging by the position of the tip-up seats they are for staff and perhaps emergency use, if say a coffee gets spilled on a seat.
    3. Each car has a pair of tables, where four can sit. As Lumo’s business model allows early booking, if you and your partner want to take the kids to see granny on her birthday, you should be able to get a table, by booking early.
    4. There are two bike stores in Coaches B and D.

These are some further thoughts.

Toilet Provision

I was on an LNER Class 800 train earlier this week and needed to go to the toilet.

    • I wasn’t sure which way I needed to go, as I couldn’t see a sign pointing me to the toilet, but in the end I struck lucky.
    • You don’t have that problem with Lumo’s trains, as there appears to be a toilet at both ends of the three middle coaches, either in your car or the next.
    • If you’re in one of the driver cars, there is an accessible toilet at the blunt end.

I don’t think anybody will argue with the toilet provision on Lumo’s trains.

Typically a Boeing 737 or an Airbus A320 will have two toilets for about 160 passengers.

Lumo’s trains have two accessible toilets and two ordinary ones for 406 passengers.

Ease Of Boarding

If you want to catch a train at virtually any station in the UK, in most cases, you just turn up something like fifteen minutes before the departure time, present your ticket and get on the train.

Planes used to be like that in the UK, but they aren’t any more.

Catering

In the article in The Times, Matt Lee, who is Lumo’s customer experience director, said they have been free to develop their own systems. He says this about the catering.

Catering will be a Deliveroo-style service: passengers can order M&S or Pret sandwiches in advance and have them delivered to their seat. “We are a testbed for other FirstGroup train operators.

Will they do gluten-free?

Luggage

Lumo have a luggage courier service called LumoLuggage.

Service Expansion

Suppose an airline or a train operating company wants to run additional services to add capacity to a route.

With an airline, they will need to obtain additional take-off and landing slots to fly the route.

But Lumo are running five-car trains on a route, where all the stations can handle nine-car trains and possibly a pair of five-car trains.

So Lumo just add extra cars to the fleet, so that they match the number of cars running on the route to the demand.

The only costs to increase the capacity are those of the extra cars and a proportionate number of extra staff.

Conclusion

I can see this service model being copied by other train operators in other countries.

I’m looking forward to going North on Wednesday.
