Could Train Services At Liverpool Lime Street Station Be Made Carbon-Free?

This map from OpenRailwayMap shows Liverpool Lime Street station.

Note.

  1. There are ten platforms, which are arranged in two sets of five.
  2. Electrified tracks are shown in red.
  3. 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.

  1. tpd is trains per day
  2. tph is trains per hour
  3. 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

Hydrogen Rail Project Collaboration Launched By Angel Trains And University of St Andrews

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

This is the sub-heading.

Angel Trains, the UK’s largest rolling stock company, has partnered with the University of St Andrews to support an innovative hydrogen train project.

On Friday 29th September, an event was held to mark the donation of a hydrogen electrolyser to the university by Angel Trains. The electrolyser will form an integral part of the university’s ongoing, cutting-edge green hydrogen research.

This is the first paragraph.

The donation follows Angel Trains’ support for the delivery of Scotland’s first zero-emission hydrogen-powered train. The project entailed the conversion of a three-car Class 314 train to a hydrogen fuel cell electric powertrain. The electrolyser was key to enabling the trial to successfully demonstrate how a green-energy fuel cycle would work.

Hopefully, this initiative will lead to better use of hydrogen on the railways of the UK.

Ricardo Develops Advanced Ranger HEX 6×6 Conversion With Hybrid Electric Drivetrain

The title of this post, is the same as that of this press release from Ricardo.

This is the sub-heading.

The new vehicle has been conceived to help improve the sustainability of future defence mobility while retaining the highest performance demanded by the toughest environments

This picture is from the press release.

My first thought is that it looks the ultimate technical.

These two paragraphs introduce the vehicle.

Ricardo, a global strategic, environmental, and engineering consulting company, has developed the Ranger HEX, a 6×6 vehicle conversion designed to offer a significant improvement in payload of up to 3,800kg over the harshest of terrains. It comes with a hybrid drivetrain to maintain performance and improve fuel consumption.

This new conversion benefits from Ricardo’s expertise and experience in creating high quality, cost effective special vehicles for defence, security and utility applications. The vehicle will benefit from enhanced levels of capability, robustness and availability.

These three paragraphs describe the design.

The HEX solution differs from conventional conversions as it has been conceived as an overlay bolt-on system that does not require any alteration of the Ford Ranger base vehicle, which is Europe’s number one commercial pick-up platform. This ensures that the base vehicle retains all the robustness and quality of the standard vehicle and allows the system to be removed and re-installed on a different vehicle.

An electric rear drive system has been adopted that uses a production Ford drive unit to provide up to an additional 210kW of power, over and above the class leading 186kW of power from the existing 3.0L V6 diesel engine. The De Dion rear suspension design is not only weight efficient and robust but also provides better wheel control for improved traction and ride. In addition, the De Dion arrangement decouples the suspension and drive systems to allow a range of drive units to be used or deleted for a cost-effective 6×4 variant with maximum payload using an undriven ‘lazy’ axle.

The electric drive is designed as a self-contained through-the-road hybrid system. Braking energy is harvested under deceleration to charge the battery pack. This energy is then used to provide electric torque under acceleration to mitigate the usual drop in performance whist carrying a high payload. A selection of battery capacities are available, depending on customer requirements. All high voltage components are contained within a single integrated enclosure for safety and ease of maintenance and repair.

Note.

  1. The conversion would appear to bolt on to the standard Ford Ranger base vehicle.
  2. The vehicle has regenerative braking.
  3. It has a payload of 3.8 tonnes.
  4. It appears to have a very sophisticated rear suspension.
  5. Judging by the colour and the mention of the word defence in the article, I suspect this vehicle has been initially designed for a military application.
  6. Over 300,000 Rangers were sold worldwide in 2021.
  7. In the UK, it looks like a Ford Ranger will cost around £30,000 excluding VAT.

In addition I’ve read in this article on Autoweek that, the conversion itself has been designed as an overlay bolt-on modification that requires no alterations to the base vehicle, even preserving its existing warranty.

I have my thoughts.

Applications

The press release talks about high quality, cost effective special vehicles for defence, security and utility applications.

Use your imagination!

Perhaps.

  • It is going to be used as the ultimate technical by the Ukrainians.
  • A missile manufacturer has a system, that weighs around 3.5 tonnes and needs a launch vehicle.
  • The RNLI needs an affordable vehicle to launch lifeboats from the beach.
  • It is going to be used as rough terrain ambulance.
  • It would make an excellent towing vehicle.

With all the problems in Morocco and Libya at the moment, it has been launched at the right time.

Zero-Carbon Operation

I believe that a zero-carbon version is essential. Especially, as the sub-heading mentions sustainable defence mobility.

The easiest way to achieve this would be to run on HVO or some form of biodiesel.

I suspect between them Ford and Ricardo have enough knowledge to create a hydrogen powered version.

Are There Autonomous Ford Rangers?

Google says, “Yes!”

This article on foresttech is entitled Ford Ranger Goes Fully-Autonomous, where this is said.

An Australian mining group has advanced the future of mobility (in mining at least) with the deployment of a fleet of fully-autonomous Ford Rangers at one of its mines.

Fortescue Metals Group has retrofitted four Rangers at its Christmas Creek mine in Western Australia with autonomous systems created by the company’s Technology and Automation team, to remove the need for fitters to make around 12,000 28-kilometre round trips each year to collect equipment and parts.

Of course, it’s not quite as ground-breaking as it sounds: mining operations don’t need to deal with road rules, pedestrians or many other vehicles, which hugely complicate the matter. Nevertheless, it’s still impressive.

Three applications suggest themselves.

  • Delivering supplies in a disaster zone, after an earthquake, flooding,, landslide or volcanic eruption.
  • Delivering supplies, including ammunition on a battlefield.
  • Moving supplies along a long linear construction site, like a new railway or road.

Note.

In all three applications, six-wheel drive will be important, if ground conditions are bad.

  1. Could Fortescue Metals Group be behind this project?
  2. Disasters seem to be getting more common.
  3. Autonomous battlefield delivery must be safer for personnel.

I suspect there will be agricultural applications of an autonomous vehicle.

Signalling Team Trials Hydrogen Power

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

These two paragraphs outline the project.

The use of hydrogen to provide power for staff welfare compounds and to recharge battery tools and electric vehicles has been tested by Colas Rail UK’s signalling team during a project in the Gloucester area.

H-Power Tower fuel cell stacks designed by AFC Energy to replace diesel generators at off-grid construction sites were used to provide power for Eco-Cabins supplied by Sunbelt Rental. The H-Towers were also used to recharge battery-operated equipment and electric-hybrid vehicles.

There has been a large saving in carbon emission during the work.

Whilst living in the Suffolk countryside for nearly forty years, we had three major power outages.

The first was the smallest and Eastern Electricity or whoever it was around 1980, needed to change the transformer that fed the village where we lived. So a diesel generator was plugged in and it fed the village, whilst the new transformer was connected.

Then in the Great Storm of 1987, where we were without power for fourteen days until a load of happy foreigners from the other side of Offa’s Dyke, got the system up and singing again. I think today, that waiting two weeks to be reconnected would be unacceptable. Although the problems in 1987, were more down to the considerable amount of damage in Suffolk.

The last time, the power went just as we were going to bed on a summer evening.

We woke to find that the power had been restored.

The manner of the restoration was a textbook case of how power outages can be solved.

  • Our house and the farm buildings around it, were fed from a transformer up a pole in the hedge by the drive.
  • A driver who had known what they were doing had backed a full-size articulated lorry into the field alongside the transformer.
  • Inside the trailer was a diesel generator and this had been connected to the transformer.
  • When I investigated early in the morning, an engineer appeared from inside the trailer and asked if everything was OK.
  • I said it was and asked a few technical questions.
  • It turned out, that someone had brought the overhead cables down, whilst moving a load of straw near the prison.

So as our house was on one end of the cable that connected a few villages and farms  to the grid, by temporarily connecting their mobile generator to the transformer everybody could be reconnected until the damage done near the prison could be repaired.

How long will it be before emergencies like these are handled by generators powered by hydrogen rather than diesel?

In HS2 Smashes Carbon Target, I describe how High Speed Two are making use of hydrogen electricity generators.

In UK Consortium To Develop Mobile Hydrogen Refuelling For Construction Sites, I talked about a UK government project to develop the hydrogen refuelling  technology for construction sites. This would also work for the refuelling of emergency generators.

I can envisage the development of a series of zero-carbon hydrogen-powered trucks with onboard hydrogen generators of different sizes.

Conclusion

Hydrogen will bring a revolution in how we provide power on construction sites, in emergencies and in remote areas.

Government Hydrogen Boost To Help Power Kimberly-Clark Towards 100% Green Energy Target

The title of this post, is the same as that of this press release from Kimberly-Clark.

These five paragraphs describe how Kimberly-Clark is decarbonising their manufacture of household products.

Three green hydrogen projects that Kimberly-Clark is developing with energy industry partners have won places on the UK Government’s Hydrogen Business Model Strategy (HBMS) shortlist.

The scheme will kickstart the UK’s low carbon hydrogen economy by funding a first-round allocation of 250MW of electrolytic hydrogen projects across England, Scotland and Wales.

Kimberly-Clark, the parent company of leading household brands including Andrex®, Kleenex®, Huggies®, WypAll® and Scott®, expects to reduce its natural gas consumption in the UK by 61% when these three projects are operational at the end of 2025, subject to final government contract.

The three hydrogen projects selected by The Department for Energy Security and Net Zero (DESNZ) include a green hydrogen hub in Barrow-in-Furness. Being developed in partnership with Carlton Power, the Barrow Green Hydrogen hub will power Kimberly-Clark’s Cumbria manufacturing facility.

The other two projects are being developed in partnership with HYRO, a joint venture between Octopus Energy Generation and renewable energy company RES, and will see green hydrogen supplied to Kimberly-Clark’s manufacturing facilities in Flint, North Wales, and Northfleet in Kent. In total, the three schemes are expected to provide a total of 50MW of green hydrogen.

Will toilet paper and tissues be softer, if they are made with hydrogen?

I won’t change the products, I use, as I already use Andrex and Kleenex.

Germany ‘A Laughing Stock’ After Minister’s Plane Grounded

The title of this post, is the same as that of this article in The Times.

This is the first paragraph.

Faulty wing flaps on an ageing Airbus have left officials red-faced after Germany’s foreign minister was forced to abandon the plane en route to Australasia.

Germany’s foreign minister is Annalena Baerbock, who is a Green Party politician.

A lot of the comments are asking, what was a Green Party politician doing flying all the way to Australia in a fuel-hungry four-engine Airbus A 340.

The article got me thinking.

Consider.

  • Government ministers, diplomats and some business people, will always need to fly around the world for some important face-to-face meetings.
  • Perhaps, this won’t happen as much as it did in the past with the development of better communications technology, but there will always be a need in some cases.
  • There are over 20,000 business jets in service.
  • Most business jets could be run on sustainable aviation fuel.
  • Some business jets have a very long-rage.

I can see one of the manufacturers developing sustainable business aircraft to fit various segments.

Lightweight Zero-Carbon Business Aircraft

Aircraft like the Eviation Alice will dominate this field.

  • The aircraft is battery-powered.
  • It can carry nine passengers.
  • It has a range of 440 nautical miles.
  • It can operate as either a feeder airliner, business aircraft or small parcel carrier.
  • It is planned to be in service in 2027.

The Alice already has a substantial order book.

There are several other aircraft in this segment under development.

Lightweight Hybrid-Electric Business Aircraft

Aircraft like the Faradair BEHA are under development.

  • The aircraft is powered by a Honeywell turbo generator running on sustainable aviation fuel.
  • It can carry eighteen passengers.
  • It has a range of around a thousand miles.
  • It is being developed at Duxford Airfield.
  • The aircraft has a radical quick-change interior.
  • Operational trials are planned to start in 2026.

Like the Alice the Faradair BEHA is different.

Lightweight Business Aircraft Running On Sustainable Aviation Fuel

I can see several of the smaller business aircraft being certified for sustainable aviation fuel.

Cessna sold 8,000 of their Citation jets in 2022 and have delivered around 7,500 according to Wikipedia.

Cessna won’t be giving up that market without a fight.

Certifying the aircraft to run on sustainable aviation fuel would be the interim solution until a hydrogen-powered business aircraft becomes available as it surely will.

The biggest problem will be to make enough sustainable aviation fuel.

Long-Range Business Aircraft Running On Sustainable Aviation Fuel

Long-range business jets like the Gulfstream G800 are true intercontinental transport.

  • They can carry nineteen passengers and sleep ten.
  • Range is 8,000 nautical miles.
  • The jets are powered by Rolls-Royce Pearl 700 engines.
  • This press release from Rolls-Royce is entitled Rolls-Royce Conducts First Tests Of 100% Sustainable Aviation Fuel For Use In Business Jets.

I think it is right to assume that long-range business jets like the Gulfstream G800 will be able to fly intercontinental routes on a net-zero basis.

An Airbus A321 XLR Running On Sustainable Aviation Fuel

Airbus and to a certain extent Boeing are the elephants in the room.

Airbus have launched an A321 XLR for long routes.

  • The aircraft can carry over 200 passengers.
  • It can fly up to 5,400 miles.
  • It is selling well.
  • Air Canada are thinking of using the plane on transatlantic routes.

The engines are from either CFM or Pratt & Whitney and I would be very surprised if the aircraft couldn’t run on sustainable aviation fuel.

Conclusion

I can see a new pattern of flying developing.

To return to the case of Germany’s foreign minister, I could see her going to Australia in a long-range business jet like the Gulfstream G800 running on sustainable aviation fuel.

  • She might take a flight from Berlin or perhaps a more convenient airport with a rail connection.
  • The plane would refuel in the Middle East and possibly Singapore.

It would be interesting to see how her green supporters reacted.

I can also see Airbus A321 XLRs running on sustainable aviation fuel across the Atlantic, being marketed as the net-zero way to the USA.

After all, Lumo market themselves as the net-zero way to Scotland against the airlines.

Lord Bamford: We’re Too Mesmerised By Musk — Here’s Why I’m Building A Hydrogen JCB

The title of this post, is the same as that of this article in the Sunday Times.

This is the sub-heading.

JCB’s Lord Bamford has spent £100m on a hydrogen engine. Tesla’s tech won’t suit everyone, he tells Jim Armitage

These are my thoughts.

The Need For Zero-Carbon Construction Equipment

Construction sites can be dangerous places and in addition to the obvious dangers, there are hidden pollutants in the atmosphere on sites.

Health and Safety will surely demand an improvement in air quality on construction sites for the protection of the workforce and nearby residents.

If JCB can produce zero-carbon construction equipment, then whether it is electric or hydrogen, this will be to their advantage.

High Speed Two And Low-Carbon Construction

High Speed Two is the UK’s biggest construction project and these posts on this blog, talk about low-carbon construction.

If High Speed Two are thinking this way, how many other projects will be built in a similar way?

Decarbonising Cargo Handling

It should be noted that JCB are involved in Freeport East at Felixstowe/Harwich.

Ports will be the sort of workplaces, where all vehicles should be zero-carbon, to protect the workforce. Some of the container handling machines are large and would be ideal for hydrogen.

Decarbonising Agriculture

JCB also make tractors, like the Fastrac and other equipment for agriculture. As they often work around people, hydrogen could be much better.

New Markets

Zero-carbon engines will result in new products for new markets.

Lord Bamford is on track to create valuable new markets for his diggers and other equipment.

Hydrogen-Powered Land Speed Record

JCB already hold the land speed record with the JCB Dieselmax, at over 350 mph.

This paragraph from Wikipedia describes the powerplant.

The car is powered by two specially-tuned versions of the production JCB444 powerplant, developing up to 750 brake horsepower (560 kW) each (over five times the power output of the production version with 90 psi (6 bar) of boost) and featuring four cylinders and 5 litres of displacement, accompanied by two stage turbochargers, intercooler and aftercooler.

I believe that getting that amount of power out of a production diesel engine, shows that JCB’s combustion engineers could do the same for a hydrogen-powered vehicle.

Electrification Between Newbury And East Somerset Junction

In the August 2023 Edition of Modern Railways, there is an article, which is entitled GWR Seeks Opportunities To Grow.

This is the sub-heading.

Managing Director Mark Hopwood tells Philip Sherratt there is plenty of potential to increase rail’s economic contribution.

This is two paragraphs.

The desire to provide electrification to support aggregates traffic from the Mendip quarries could also benefit GWR , says Mr. Hopwood. ‘Having an electric loco would massively help with pathing heavy freight trains through the Thames Valley. If you could electrify from Newbury to East Somerset Junction, a big chunk of the Berks and Hants route would be wired.

Then you can ask how much further you could get on battery power on an IET without running out of juice.’

I have some thoughts.

Where Is East Somerset Junction?

This OpenRailwayMap shows East Somerset junction.

Note.

  1. The East Somerset junction is marked with the blue arrow.
  2. East Somerset junction is 5.2 miles North of Bruton station and 5.4 miles South of Frome station on the Reading and Taunton Line.

As the map shows there is a branch to Merehead Rail Sidings, which is shown in yellow.

This Google Map shows Merehead Rail Sidings.

Note.

  1. It looks like there is a massive quarry to the North of the A361 road, which curves across the map.
  2. It is labelled Torr Works – Aggregate Industries.
  3. Torr Works has a Wikipedia entry.
  4. The rail sidings are South of the A361.
  5. Zooming in on the map, shows that the railway between East Somerset junction and Merehead is single-track and only a few miles long.

Distances from East Somerset junction are as follows.

  • Dorchester junction – 41.2 miles
  • Newbury – 53.4 miles
  • Taunton – 37.2 miles
  • Weymouth – 47.8 miles

Note that it is electrified with 750 VDC third-rail between Weymouth and Dorchester junction.

Range of Battery-Electric Trains

Consider.

  • A Bombardier engineer told me eight years ago, that the battery-electric Class 379 train had a range of sixty miles.
  • Stadler’s FLIRT Akku has a Guinness world record of 139 miles on one battery charge. See this page on the Stadler web site.
  • Even Stadler’s Class 777 trains for Merseyrail have a range of 84 miles on battery power. See New Merseyrail Train Runs 135 km On Battery.

It does appear that five-car battery-electric trains will have ranges in excess of a hundred miles.

I believe that because Hitachi’s battery makers have a good record, they will probably be very ambitious and will want that Guinness record, that Hitachi’s Class 802 trains will have a battery range not far short of the 139 miles of the Stadler FLIRT Akku.

I will be very surprised if Hitachi’s battery-electric version of a Class 802 train, doesn’t have range of at least 125 miles.

But say if they could do say 140 miles, the battery-electric Class 802 train could cover every long-distance route in the UK, which would attract orders for trains to run on the following routes.

  • Cardiff and Swansea
  • Crewe and Holyhead
  • Edinburgh and Aberdeen
  • Edinburgh and Inverness
  • Crewe and Holyhead
  • London Waterloo and Exeter St. Davids

A substantial reward to the battery makers, would probably not be out of order.

Aggregate Trains From The Mendips

Consider.

  • Mining and quarrying companies are under pressure from governments, shareholders and environmentalists to reduce their carbon footprints.
  • Many are replacing diesel-powered mining excavators and trucks, with electric or hydrogen versions.
  • In addition, those companies delivering building products to the construction industry are under pressure to provide low-carbon products.
  • Using rail with electric traction to deliver products to market would cut carbon emissions and might even help sales.

These Mendip quarries appear to be connected to the Reading and Taunton Line.

  • Torr Works – Connects 5.4 miles to the South of Frome.
  • Whatley Quarry – Connects close to Frome.

There may be others.

But these rail-connected quarries, connect at or North of East Somerset junction, to where Mark Hopwood is proposing electrification.

Zero-carbon rail traction could even be possible, by electrifying the short single-track branch lines. or by using hydrogen-electric hybrid locomotives.

GWR’s London And South-West Services

These services use the Reading and Taunton Line to join the Bristol and Exeter Line at Taunton, before going on to Exeter, Plymouth and other destinations in the South-West of England.

These are distances from East Somerset Junction.

  • Exeter – 67 miles
  • Paignton 95.2 miles
  • Penzance – 198.5 miles
  • Plymouth – 119.0 miles
  • Taunton – 37.2 miles

Note.

  1. Exeter, Paignton, Penzance and Plymouth stations would need short lengths of electrification to charge terminating trains or top-up passing trains.
  2. In Thoughts About Electrification Through Devon And Cornwall, I showed that the average stop time at Plymouth station was eight minutes, which could be enough for the rail equivalent of a Formula One splash and dash.
  3. A 125 mile battery range, not only enables London and Penzance, but also Cardiff and Swansea, and Edinburgh and Aberdeen, when the extra electrification is completed.

Could my estimate of a 125 mile battery range, be Hitachi’s objective for their battery-electric trains?

The Ultimate Battery-Electric Class 802 Train

Hitachi have been totally silent on how the fitting of batteries to Class 802 trains is going.

But Mark Hopwood is more forthcoming in the GWR Seeks Opportunities To Grow article. where this is said.

Meanwhile, GWR had announced plans with Eversholt Rail to trial the replacement of a diesel generator unit with batteries on a Class 802 IET. However, Mr. Hopwood says this would not be useful for GWR and so the trial is not proceeding; instead, a TransPennine Express Class 802 will be the subject of a battery trial.

It sounds to me that another solution is being developed to get trains to run on electric power between London and the South-West.

  • I think we can rule out full electrification on the grounds of cost, disruption, time and the Nimbys and objectors will have a field day.
  • Newbury and Penzance is a distance of 251.9 miles, which would surely need a lot of batteries.

Mark Hopwood’s idea to electrify the 53.4 miles between Newbury And East Somerset junction, is starting to look like a good compromise.

GWR’s Bristol/Gloucester And Weymouth Services

These stopping trains are run by diesel trains and take the following route between Bristol Temple Meads and Weymouth stations.

  • Keynsham

Note.

  1. I would assume that there is enough electrification at Bristol Temple Meads and towards Gloucester to charge the trains.
  2. Trains would leave Bristol Temple Meads with a full battery.
  3. The eighteen stops mean that an electric train with regenerative braking will be more efficient.
  4. Bristol Temple Meads and Westbury is not electrified.
  5. Westbury and East Somerset junction will be electrified with 25 KVAC overhead electrification under Mark Hopwood’s proposal.
  6. Trains take sixteen minutes between Westbury and East Somerset junction.
  7. East Somerset junction and Dorchester junction is not electrified.
  8. Dorchester junction and Weymouth is electrified with 750 VDC third-rail electrification.
  9. Trains take ten minutes between Dorchester junction and Weymouth.

  • East Somerset junction and Dorchester junction – 41.4 miles – Not Electrified
  • Dorchester junction and Weymouth – 6.6 miles – Electrified

The two sections without electrification, should be well within range of a dual-voltage battery-electric train, that has been designed for the route.

  2. I would assume that there is enough electrification at Swindon to charge the trains.
  3. Trains would leave Swindon with a full battery.
  4. An electric train with regenerative braking will be more efficient.
  5. Chippenham and Westbury is not electrified.
  6. Westbury station will be electrified with 25 KVAC overhead electrification under Mark Hopwood’s proposal.
  7. Trains would leave Westbury with a full battery.

Distances of the various legs are as follows.

  • Swindon and Chippenham – 16.9 miles – Electrified
  • Chippenham and Westbury – 15.8 miles – Not Electrified

The section without electrification, should be well within range of a battery-electric train, that has been designed for the route.

What Can Be Done If The Electrification Is Not Long Enough?

Some of these routes battery-electric routes may need more electrification to work efficiently.

Despite some routes having both 25 KVAC  overhead and 750 VDC third-rail electrification, any extension of the electrification would be overhead, as new third-rail electrification is effectively banned.

Conclusion

It looks like Mark Hopgood proposal is an excellent idea to enable the decarbonisation of GWR services in Wiltshire and Somerset.

  • Express services would be run by battery-electric Class 802 trains.
  • Local services would be run by battery-electric trains with perhaps three cars.

Some of the local trains would need to be dual-voltage to use both forms of electrification.

More Government Details Emerge On How Fleetwood’s Rail Link Will Be Restored – Using Tram-Train Technology

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

This is the sub-heading.

New details have emerged about how the Government plans to restore the rail link between Fleetwood and Poulton using state-of-the-art tram-train technology.

These are points from the article, which mainly come from a letter to the local MP; Paul Maynard.

  • In a letter to Mr Maynard, Rail Minister Huw Merriman has set out for the first time how the Government intends to restore the rail link.
  • The Government is now looking at the finer details of a tram-train scheme and how the project can be funded.
  • Tram-trains will be used for the link.
  • The re-opened railway can be linked into the existing Blackpool to Fleetwood tramway, allowing services to run into the heart of Fleetwood.
  • Services would operate twice hourly from Preston station to Poulton-le-Fylde over the existing heavy rail network, before joining a new light rail link between Poulton-le-Fylde and the Denham Way roundabout on Amounderness Way, calling at up to three new intermediate stops.
  • From the roundabout, the services would continue on the existing Blackpool tram network towards Fleetwood town centre and Fleetwood ferry terminal.
  • The Government is committed to the project.

These are my detailed thoughts.

The Route

The Blackpool Gazette article describes the route like this.

Services would operate twice hourly from Preston station to Poulton-le-Fylde over the existing heavy rail network, before joining a new light rail link between Poulton-le-Fylde and the Denham Way roundabout on Amounderness Way, calling at up to three new intermediate stops.

From the roundabout, the services would continue on the existing Blackpool tram network towards Fleetwood town centre and Fleetwood ferry terminal.

This map from OpenRailwayMap shows the route.

Note.

  1. Poulton-le-Fylde station is marked by the blue arrow in the South-East corner of the map.
  2. The pink line running up the coast is the Blackpool tramway.
  3. The Blackpool tramway terminates at Fleetwood Ferry at the top of the map.

This second OpenRailwayMap shows Fleetwood Ferry tram terminus.

Note.

  1. As before, the Blackpool tramway tracks are shown in pink.
  2. There is a lifeboat station and a ferry to the other side.
  3. The tracks allow a tram to come from the South, go round the loop and return to the South.
  4. I believe that both the Blackpool tramway and the Fleetwood tram-train will both reverse direction in the same way.
  5. No new infrastructure would be needed at the Fleetwood Ferry terminal, except for perhaps a few signs.

This third OpenRailwayMap shows the track from Fleetwood Ferry to the Lindel Road tram stop.

Note.

  1. As before, the Blackpool tramway tracks are shown in pink.
  2. Fleetwood Ferry is in the North-East corner if the map.
  3. Lindel Road tram stop is marked by the blue arrow in the South-West corner if the map.

This fourth OpenRailwayMap shows the Lindel Road tram stop area at a larger scale.

Note.

  1. As before, the Blackpool tramway tracks are shown in pink.
  2. Lindel Road tram stop is marked by the blue arrow.
  3. Running parallel to and to the  East of the Blackpool tramway is Amounderness Way, which appears to have been built on the line of the railway to Fleetwood.
  4. Along the West side of Amounderness Way, a disused railway is indicated, which must be the closed railway to Fleetwood.

I believe that Network Rail or their engineers have found a route to connect the old branch line to the Blackpool tramway.

  • The railway connecting the Blackpool tramway and the closed railway to Fleetwood, would only need to be single-track.
  • There might be a convenient route, where all the land is owned by the Council.
  • If the tram-trains were to be was fitted batteries, then there would be no need to electrify the line.

I suspect, that the connection would be to the South of Lindel Road tram stop.

  • This would mean that the tram-train would serve a number of stops in the town centre.
  • The tram-train could use the catenary of the Blackpool tramway.
  • Connection and disconnection to the catenary could be done in the Lindel Road tram stop.

This Google Map shows the area of the Lindel Road tram stop and Denham Road.

Note.

  1. The Lindel Road tram stop in the North-West corner of the map, with the Blackpool tramway running NE-SW across the corner of the map.
  2. The roundabout and Amounderness Way on the East side of the map.
  3. Denham Way connecting the roundabout to Copse Road and the tram stop.
  4. On the fourth OpenRailwayMap  it showed the original line of the railway was to the West of Amounderness Way.

So could the spur between the Lindel Road tram stop and the railway to Poulton-le-Fylde station take the following route?

  • Just South of the tram stop the two tracks connect to a new single-track that goes East on the South side of Denham Way.
  • The turn would be quite sharp, but trams and tram-trains have the articulation of a snake and can use tight turns and narrow formations.
  • The crossing of Copse Road would be protected by traffic lights.

When the tram-train gets to the roundabout other end of Denham way, I think there are two choices.

  1. Turn sharp right and go South alongside the West side of Amounderness Way.
  2. Somehow cross Amounderness Way and go down the West side.

This Google Map Amounderness Way going South.

Note.

  1. Amounderness Way runs North-South down the map between two roundabouts.
  2. The large industrial area to the East of the road is labelled as SUEZ Recycling and Recovery.
  3. North-East of SUEZ is Fleetwood Marsh Nature Reserve.
  4. South-East of SUEZ is SUEZ Environmental Jameson Road Landfill and Lancashire County Council’s Fleetwood Household Waste Recycling Centre.
  5. There also seem to be a lot of large holiday caravans.
  6. There is a road running along the South-East of the large SUEZ site called Jameson Road.

The Wikipedia entry for the Fleetwood branch line, says this about the state of the branch.

Some of the line is now cleared of overgrowth because the northern track was not lifted from past Burn Naze Halt to just beyond Jameson Road Fleetwood. However, the road bridge was filled in below it. The junction, last used when goods trains took coal to Fleetwood Power Station, still exists. Looking over the road bridge on Jameson Road, the track to both north & south can still be seen through the undergrowth. In the 1990s, the new A585 The Amounderness Way bypass has been built on the former trackbed, although sufficient space still exists for a reinstated railway should it be required.

Note.

  1. It appears that enough space has been left at the Northern end to connect to the Blackpool tramway.
  2. It doesn’t seem to be in too bad a state.
  3. I suspect that rebuilding the branch has a similar degree of difficulty to rebuilding the Dartmoor Line to Okehampton, which is now operating successfully.

This gave me hope, that a single-track tramway could be built between Poulton-le-Fylde junction and the Lindel Road tram stop.

This Google Map shows the track meeting the filled in road bridge on Jameson Road.

Note.

  1. If that’s not a single-track railway and the filled-in bridge on Jameson Road, I’m a Dutchman.
  2. The railway can be followed on Google Maps for most of the way to Poulton-le-Fylde station.
  3. Google Maps also shows traces of railway to the North of the bridge on Jameson Road.

This Google Map shows the section of Amounderness Way from the North of the SUEZ Recycling and Recovery site to the Denham Way roundabout.

I suspect that the tram would go straight up the East side of ‘Amounderness Way.

But how would the tramway cross the road.

This Google Map shows Denham Way, the roundabout and Lindel Road tram stop.

I am fairly sure that a single-track bridge of some sort could connect Lindel Road tram stop with a single-track railway along the East side of Amounderness Way, to link up with the orphaned track South of Jameson Road.

This OpenRailwayMap  shows Poulton-le-Fylde junction, where the former railway to Fleetwood, joins the Blackpool branch.

Note.

  1. Poulton-le-Fylde station is indicated by the blue arrow.
  2. The orange track is the Blackpool branch to Blackpool North station.
  3. Poulton-le-Fylde junction is to the West of the station.
  4. The track going North from the junction, is the disused track to Fleetwood.
  5. The map also shows a couple of level crossings.

I am fairly certain, that a single-track tramway could be built between Poulton-le-Fylde junction and the Lindel Road tram stop.

This OpenRailwayMap  shows Poulton-le-Fylde junction and Poulton-le-Fylde station.

These pictures taken in 2018, show Poulton-le-Fylde station.

Note.

  1. It is a small station, that oozes quality.
  2. The tracks and electrification were all installed or renewed in the last few years.
  3. There is even a cafe and a lift to the street.
  4. The flower-beds in the middle of the platform, are at the Preston end of the station.
  5. As the tram-trains will stop in the station, they can raise and lower the pantograph in the station.
  6. Tram-trains and trains will share the appropriate platform.

The possibility can probably be arranged that an incoming train to Blackpool North will be able to drop passengers at a waiting tram-train for Fleetwood Ferry.

Will The New Fleetwood Branch Be Electrified?

There are various arguments for and against electrification between Poulton-le-Fylde station and the Lindel Road tram stop.

In favour, is that a continuous catenary can be run from end-to end, with 750 VDC electrification.

  • An insulated section would be used at Poulton-le-Fylde station to separate the 750 VDC of the tramway and the 25 KVAC of the Blackpool branch.
  • Standard tram-trains, like Sheffield’s Class 399 tram-trains could be used.
  • Battery-electric tram-trains are probably more expensive.

Against electrification are.

  • There would be no electrification between Poulton-le-Fylde station and the Lindel Road tram stop to install.
  • There would be no need for any modifications to the catenary at Poulton-le-Fylde station and the Lindel Road tram stop.
  • The filled in bridge mentioned in Wikipedia, might only need a tram-sized hole and not complete rebuilding to get the trams through.
  • Occasional freight trains could probably be run, if required.
  • Battery-electric tram-trains are proven technology.

It will definitely one for the accountants to decide.

The Tram-Trains

These are pictures of Stadler Citylink tram-trains in Sheffield.

Note.

  1. These Class 399 tram-trains were the first tram-trains to run in the UK, when they entered service in 2017.
  2. They were built by Stadler in Spain.
  3. They share the tracks in Sheffield happily with Sheffield’s other trams of a different type.
  4. At the time, Paul Maynard, who is the local MP, was the Parliamentary Under Secretary of State for Transport, so I suspect that explains, why the MP appears pleased with the choice of tram-trains and talks knowledgeably about them.
  5. There is also a battery electric version of these tram-trains, which has been ordered by the South Wales Metro.
  6. Blackpool’s tramway uses Bombardier Flexity 2 trams. However, it doesn’t seem, that there is a tram-train version of the Flexity 2.
  7. Merseyrail in the Liverpool area, are introducing a large fleet of Stadler trains, which will be running to Preston in a couple of years.

I suspect that these tram-trains will be built by Stadler and they could be fitted with batteries.

Tram-Train Frequency Between  Fleetwood Ferry And Poulton-le-Fylde Station

The Blackpool Gazette article is definite, that the frequency of the tram-train will be two trains per hour (tph).

Consider.

  • The Blackpool tramway operates a service of trams every 10-15 minutes between Starr Gate and Fleetwood Ferry, so the frequency will be increased by two tph North of Lindel Road tram stop.
  • As heritage trams also share the route to Fleetwood, I suspect that at some busy times, the Fleetwood Ferry and Preston service could be reduced to hourly.
  • But it does look to me, that the all-important terminal at Fleetwood Ferry has been well-designed and can handle the extra traffic.
  • Looking at the timetable for the Blackpool tramway, trams take forty-one minutes between Fleetwood Ferry and the North Pier.
  • As Poulton-le-Fylde station and North Pier tram stop, are probably similar distances from Fleetwood Ferry,  I suspect that Poulton-le-Fylde station and Fleetwood Ferry would take thirty minutes or more.
  • Real Time Trains indicates that electric trains to Blackpool North station take around 16-17 minutes between Poulton-le-Fylde and Preston stations, with diesel trains taking a couple of minutes more.
  • Add in time for stops at Kirkham & Wesham, possibly another at Salwick and cleaning and crew changeover at Preston station, I suspect that a roundtrip from Preston to Fleetwood Ferry and back will take a very convenient two hours.

A two hour round trip and two tph, will mean four trains will be needed to work the timetable.

I can’t prove it, but I my gut feeling is that there there will be a passing loop somewhere between Poulton-le-Fylde station and the Lindel Road tram stop.

The passing loop would also give scope for operational flexibility.

Train Services Through Poulton-le-Fylde Station

Train services through Poulton-le-Fylde station are currently as follows.

  • Avanti West Coast – London Euston and Blackpool North – 1 train per day (tpd)
  • Northern – Liverpool Lime Street and Blackpool North – 1 tph
  • Northern – Manchester Airport and Blackpool North – 2 tph
  • Northern – York and Blackpool North – 1 tph

Note that all trains stop at Preston.

The Avanti West Coast service only calls Southbound, but I wouldn’t be surprised, if the Fleetwood tram-train is built, that Avanti West Coast started a Northbound service.

Could The Blackpool South Branch Be Served By Similar Tram-Trains?

In Beeching Reversal – South Fylde Line Passing Loop, I talked about improving the Blackpool South branch.

Objectives included.

  • Two tph.
  • Better trains.
  • A passing loop that would enable the 2 tph.

Note.

  1. Pacers have been replaced with Class 150 trains.
  2. The route is electrified between Preston and Kirkham & Wesham station.
  3. 12.2 miles are without electrification.

It certainly would seem possible that if a battery-electric tram-train had sufficient range, it could handle the current route to Blackpool South station.

The trams would have a ninety-minute round trip between Preston an Blackpool South stations and two tph, will mean three trains will be needed to work the timetable.

The MP is quoted in the Blackpool Gazette article, as liking the concept of a tram loop to Blackpool from Preston.

Trams might go to Fleetwood, down the promenade and then take the Blackpool South branch beck to Preston.

It could obviously go the other way around the loop.

This Google Map shows the location of Blackpool South station.

Note.

At the West side of the map is the promenade, with tramway running North and South.

At the East side of the map is Blackpool South station.

The walking route between the tramway and the station is not arduous, but it is not a seamless transfer.

It might be better to make the connection at Blackpool Pleasure Beach, which is shown in this Google Map.

Note.

  1. The Pleasure Beach lies between the tramway and the promenade by the beach and the Blackpool South branch on the East side.
  2. There are two stops on the tramway and a station just to the South.

Perhaps, if the Pleasure Beach were redeveloping an area, they might leave provision for tram-trains to  to sneak through to join the tramway going North.

But it’s a difficult problem, as there is not much space, that is undeveloped and the roads aren’t very wide.

This Google Map shows the North Pier and Blackpool North station.

Note.

  1. The North Pier is in the South-West corner of the map.
  2. Blackpool North station, which is Blackpool’s main station is in the North-East corner of the map.
  3. The tramway runs along the sea-front.

The North Pier and the station are linked by Talbot Road.

This Google Map shows Talbot Road and the development of a tram stop by Blackpool North station.

Note.

  1. To create the space a large Wilkinson’s store was demolished.
  2. Blaxkpool North station is just off the North-East corner of the map.
  3. The tram stop will have two platforms.
  4. There is a large diamond crossing on the approach to the tram stop, so operation is smooth and reliable.
  5. It looks like there will be substantial development around and possibly over the tram stop.

This Google Map shows Talbot Square, where the tram branch to Blackpool North station joins the main North-South tramway.

It is all very crowded and I believe  this illustrates, why despite their close proximity, there is no rail connection between the Blackpool South branch and the Blackpool tramway.

There just isn’t the space to put in junctions like this and the tramway doesn’t go past Blackpool Airport, so the connection would have to be amongst the crowded houses on the sea front.

The Development Of Blackpool Airport

Aviation is changing and I believe a new breed of airliners and the airports to serve them, will be developed in the next few years.

  • Zero-carbon aircraft are being developed and I believe some will have entered service by 2026.
  • They will be powered directly by batteries or from green hydrogen.
  • Some like the Eviation Alice are already entering a flight-test program, that will lead to certification.
  • These airliners are likely to be smaller and quieter than current airliners, with typically a passenger capacity of around 19 passengers.
  • They will often fly routes between smaller regional airports.

Blackpool Airport could be an ideal airport for these airliners.

  • Offshore electricity and even hydrogen generated offshore will be easy to deliver to Blackpool Airport.
  • It could have excellent transport connections with trams and trains.
  • Blackpool Airport has good runways.
  • Many take-offs will be over the sea.
  • We will see airports converting to zero-carbon airports.

So why not Blackpool Airport?

These are distances between Blackpool Airport and other airports.

  • Aberdeen – 238 miles
  • Amsterdam Schipol – 340 miles
  • Belfast City – 128 miles
  • Cardiff – 165 miles
  • Dublin – 134 miles
  • Edinburgh – 150 miles
  • Exeter – 211 miles
  • Geneva – 661 miles
  • Glasgow – 155 miles
  • Haverfordwest – 157 miles
  • Jersey – 318 miles
  • Kirkwall – 358 miles
  • London Gatwick – 220 miles
  • London Heathrow – 192 miles
  • London Southend – 219 miles
  • Newcastle – 89 miles
  • Paris Orly – 422 miles
  • Isle of Man Ronaldsway – 68 miles
  • Shannon – 254 miles
  • Southampton – 208 miles
  • Sumburgh – 427 miles

These distances fit nicely with the range of the nine-seater Eviation Alice electric aircraft, which is predicted to be 620 miles.

This Google Map shows Blackpool Airport.

Note.

  1. The East-West main runway, which is over 1,800 metres long, which will probably mean an easier takeoff into the wind, for much of the time.
  2. The acres of space.
  3. The Blackpool South branch running down the side of the airport, with Squires Gate station on the road past the Airport.
  4. But zoom in on the airport and some improvement and refurbishment needs to be done. Years of neglect and uncertainty has taken its toll.

This Google Map shows the North-West corner of the map at a greater scale.

Note.

  1. In the North-West corner of the map is Blackpool tramway’s depot and Starr Gate tram stop with its loop.
  2. The rail station is Squires Gate for Blackpool Airport.
  3. The smart green space to the East of the railway is Blackpool FC’s training ground.
  4. Below the training ground on the East side is Blackpool Airport.
  5. On the other side of the track from the Airport, it appears to be the local rubbish dump.

I wonder, if this is where the Blackpool tramway and the Blackpool South branch could be joined up.

  1. A joint two-platform station partly on Airport land would replace the current Squires Gate station.
  2. It could be connected to the Airport terminal by some form of shuttle or travellator.
  3. The trams would be connected to the Starr Gate loop by a line going along the front, as the tramway does in much of Blackpool, before cutting through the waste ground.
  4. Trains to Blackpool South station would use their current route.

This plan and probably lots of others could allow a Blackpool loop tram-train from Preston.

What would a zero-carbon airport do for Blackpool?

Ecojet: Dale Vince Launches An Aviation Revolution

The title of this post is the same as that as this news story from Ecotricity.

This is the sub-heading.

The world’s first electric airline powered by renewable energy

These three paragraphs outline the project.

Ecotricity founder, Dale Vince, has announced the launch of Ecojet, the world’s first Electric Airline, powered by renewable energy. The move marks the beginning of an aviation revolution by making net-zero, emission-free air travel possible for the first time.

Ecojet’s fleet will comprise conventional planes retrofitted with hydrogen-electric powertrains. Once converted, the aircraft will operate with the same power output as before, but with a one-hundred percent reduction in CO2 emissions.

The decision to repurpose old planes rather than build new models from scratch will save 90,000 tonnes of carbon per year. The only byproduct will be water, which can be captured and released into the lower atmosphere to avoid the harmful effects of contrails.

These ae my thoughts.

The Aircraft

The news story contains pictures of two aircraft; a de Havilland Canada Twin Otter and a 737 or A320 variant.

  • It also says that hydrogen-electric powertrains will be used.
  • ZeroAvia in partnership with Cranfield Aerospace are developing such a powertrain and I suspect they could have one certified by 2025.

This would be used in the Twin Otter.

But what about 737 or A320 variant?

Airbus are already proposing the ZEROe Turbofan, which appears to be based on an improved A320 neo.

But the image on the news story looks more like a Boeing 737 from the wing-tips.

This article on the IET web site, which is entitled Airbus And Boeing To Embrace Hydrogen From Mid-2030s, indicates that it will be the mid-2030s before hydrogen twinjets of this size are in service.

This paragraph from the news story indicates his philosophy about the aircraft.

Short-term, to secure routes and a license from the Civil Aviation Authority, Ecojet will initially launch using conventionally fuelled planes. Ecojet will launch with two different sizes of turboprop aircraft (a 19-seat aircraft and a 70-seat aircraft). These aircraft will be retrofitted with the hydrogen-electric powertrains as they become approved for service by the CAA – the first retrofits will take place in 2025, one year after the commencement of flights.

Note.

  1. The news story clearly states that two types of aircraft will be used; a 19-seat turboprop and 70-seat turboprop.
  2. So the second picture of a Boeing 737 had nothing to do with the news story.
  3. They will be retrofitted with hydrogen-electric powertrains, when they have been certified.
  4. Flights are planned to start next year.

It looks a very canny philosophy, as Ecojet will be able to prove the route with aircraft running on traditional fuels or sustainable aviation fuel (SAF) and only switch to hydrogen, when the hydrogen-electric powertrains are proven, certified and installed, and the hydrogen infrastructure is in place.

The Smaller Aircraft

The first picture in the news story is of a de Havilland Canada Twin Otter.

  • This aircraft accommodates 19-20 passengers.
  • It has two turboprop engines.
  • Production started in 1966 and it is still ongoing.
  • Nearly a thousand have been built, so plenty of nearly-new examples will be available for refurbishment and conversion.
  • Loganair operate three aircraft in Scotland.

It looks fairly certain, that Ecojet’s 19-seat aircraft will be a Twin Otter.

The Larger Aircraft

Possibilities would include these aircraft.

Note.

  1. Both aircraft are still in production.
  2. In ZeroAvia To Bring Zero-Emissions Flight To Sweden, I talk about how ZeroAvia have sold their hydrogen-electric powertrains to Swedish ATR-72 operator; Braathens and are targeting Dash 8 operators.
  3. In Universal Hydrogen Successfully Completes First Flight Of Hydrogen Regional Airliner, I talk about Universal Hydrogen’s successful progress in selling hydrogen-electric powertrains for ATR-72s and Dash 8s. The first flight of their system was in an ATR-72.

It looks to me, that Dale Vince has a choice of two 70-seat aircraft and hydrogen-electric powertrains from two manufacturers; ZeroAvia and Universal Hydrogen.

In Monte To Purchase 100 FC Aircraft Drives From ZeroAvia, I talk about how Monte Aircraft Leasing have done a deal with ZeroAvia to lease ZeroAvia’s hydrogen-electric powertrains to regional airlines.

Has Dale Vince done a deal with Monte Aircraft Leasing for his aircraft?

  • Monte Aircraft Leasing and ZeroAvia would get an eco-celebrity customer, who could even be the launch customer.
  • Ecojet’s aircraft would all have similar ZeroAvia hydrogen-electric powertrains, although the size might be different.
  • Dale Vince would only be sharing the risk, if the technology was a dog.
  • De Havilland Canada and/or ATR will see how the passengers like zero-carbon flight.

There is also, one of aviation’s most powerful companies close to the deal, as Airbus own half of ATR.

Airbus are developing the hydrogen-powered ZEROe Turboprop, which is shown in this Airbus image.

Note.

  1. It looks very much like an improved ATR-72.
  2. It has more extreme propellers and probably better aerodynamics.
  3. Airbus might like to persuade Ecojet to use ATR-72s as their 70-seat airliner.
  4. Information from an operator of hydrogen-powered airliners would be very valuable to Airbus.

I wouldn’t be surprised to see Ecojet lease some nearly new ATR-72s.

Would Airbus Fit ZeroAvia Hydrogen-Electric Powertrains In The ZEROe Turboprop?

This page on the Airbus website is entitled ZEROe.

In a section, which is entitled Hydrogen Propulsion To Power Future Aircraft, this is said.

All three ZEROe concepts are hybrid-hydrogen aircraft. They are powered by hydrogen combustion through modified gas turbine engines. Liquid hydrogen is used as fuel for combustion with oxygen.

In addition, hydrogen fuel cells create electrical power that complements the gas turbine, resulting in a highly efficient hybrid-electric propulsion system. All of these technologies are complementary, and the benefits are additive.

In 2022, we launched our ZEROe demonstrator with the aim to test hydrogen combustion technology on an A380 multimodal platform. Through future ground and flight testing, we expect to achieve a mature technology readiness level for a hydrogen-combustion propulsion system by 2025.

Note.

  1. Airbus state they are using modified gas turbine engines.
  2. Airbus also talk about using fuel cells to create electrical power that complements the gas turbines.
  3. Could the hydrogen fuel cells be used to power the aircraft’s systems, like avionics, control systems, air-conditioning and the hydrogen system for the main engine?
  4. This concept of effectively a hydrogen auxiliary power unit,  might be a more efficient way of using the hydrogen, which either gives longer range or a smaller fuel tank.
  5. In The ZEROe Demonstrator Has Arrived, I talk about the ZEROe Demonstrator, which is a modified Airbus A 380.

Did the adding of hydrogen fuel cells to the ZEROe aircraft, lead to the concept of a hydrogen-powered auxiliary power unit, that I talked about in Airbus To Trial In-flight Auxiliary Power Entirely Generated By Hydrogen?

It looks to me, that Airbus have developed their own simple concept of powering the aircraft.

I doubt they will need ZeroAvia’s technology.

But.

  • Aircraft manufacturers like Airbus generally fit the best and most suited engines they can find in their aircraft.
  • The Wikipedia entry for ZeroAvia says that the prototype hydrogen-electric powertrain is in the cabin, consisting of two fuel cells and a lithium-ion battery for peak power.
  • ZeroAvia have powerful shareholders like Amazon, Bill Gates and Royal Dutch Shell.
  • ZeroAvia have also received grants from the UK Government.

I wouldn’t be surprised to learn, that Airbus have taken a long hard look at ZeroAvia’s technology.

After all, ZeroAvia could probably build a hydrogen fuel cell power pack, that would meet Airbus’s needs for a hydrogen-powered auxiliary power unit.

Remember too, that many fleets of aircraft have been updated with new engines for decades and I don’t think Airbus would mind ZeroAvia giving a new zero-carbon lease of life to the hundreds of ATR-72s in service around the world.

Surely, a successful hydrogen-powered ATR-72 is only going to create more interest in airlines buying ZEROe Turboprops.

All the converted aircraft will still need support from ATR.

Both the converted and new aircraft will need hydrogen refuelling services, so could the two aircraft use a common standard.

Airbus and ZeroAvia would appear to have several common interests.

Ecojet’s Core Route

This is a paragraph from the news story on the Ecotricity web site.

Dale has partnered with experienced pilot Brent Smith and a team of aviation specialists to set up Ecojet. Flights across the UK will commence in early 2024, starting with the Edinburgh to Southampton route, and expanding to mainland Europe shortly after, with long-haul flights planned for the future.

Note.

  1. The ATR-72 has a range of 949 miles, which is more than adequate for Southampton and Edinburgh, which is just over 350 miles.
  2. Diagonal journeys in the UK are often the most passenger-unfriendly by rail and tend to use diesel trains.
  3. Southampton Airport has good road and rail connections, with the terminal less than a minute from the station.
  4. Edinburgh Airport has good road and tram connections, with rail connections needing a short journey on the tram.
  5. Southampton Airport has flights to the Channel Islands, Ireland and Schiphol.
  6. Edinburgh Airport has a comprehensive service from major airlines and low-cost carriers, and several flights to destinations in the North of Scotland and on the Islands.

I think that it is a well-chosen core route for their 70-seat aircraft.

Which Routes Will Ecojet Fly With The Twin Otters?

Consider.

  • My Scottish friends tell me that flying to the Scottish Islands, like the Hebrides, Orkney and Shetland is expensive.
  • The growth of the Scottish wind power industry will mean, that more capacity is needed to serve the North of Scotland and the Islands.
  • Tourism to the North of Scotland and the Islands is on the up.
  • There will not be a shortage of green electricity to produce green hydrogen.
  • The North of Scotland isn’t short of airports.
  • The Twin Otter has a surprisingly long range on aviation fuel and I suspect, that a hydrogen version would be designed to have a similar range.
  • The longest flight needed would probably be Edinburgh and Sumburgh, which is about 280 miles, which should be well within the range of a Twin Otter.
  • I suspect that hydrogen refuelling could be easily provided at enough airports, to support hydrogen-powered airliners.
  • I am sure, that the Twin Otters could be used on a network of zero-carbon flights from Edinburgh to the North of Scotland and the Islands.
  • A zero-carbon airline would help Scotland’s net-zero ambitions.

There is certainly a need for another airline to connect Edinburgh to the North of Scotland and the Islands and the infrastructure could be upgraded to support a hydrogen-based zero-carbon airline.

Could Ecojet build a similar network at Southampton, that served the Channel Islands, Southern Ireland and Northern France?

Conclusion

There’s a lot more to this venture, than there appears at first sight.

O wish Vince and his partners well, but as a coeliac, I’ll skip the food.
