DHL Express Determinedly On Course To Achieve Net-Zero Emissions
The title if this post is the same as that of this article on The Lodestar.
This was the introductory paragraph.
DHL Express chief executive John Pearson came out with all guns firing when detailing the firm’s efforts to hit net-zero by 2050, during a press junket this week.
The rest of the article is basically in three sections.
The Use Of Sustainable Aviation Fuel (SAF)
Summed up by three sentences.
“When it comes to sustainable aviation fuel (SAF), we know this is expensive, but we have also put a big chunk of change into this,” he said.
By the end of the year, we want 2% of flights fuelled by SAF.
DHL has bought 15% of all globally available SAF
DHL seem to have a comprehensive policy on the use of SAF.
This reinforces my view that SAF will be important.
Alternative Approaches
This paragraph sums up some of the more alternative approaches DHL are looking at.
SAF use forms only one part of the migration to net-zero: fleet renewal; decarbonising ground handling; a fuel optimisation programme; and the use of electric aircraft, following the successful September trial over Seattle of the Alice e-cargo plane, are all critical.
I suspect there are other alternative approaches.
Fleet Renewal
The last two paragraphs talk about fleet renewal.
Fleet renewal comes after a particularly pronounced moment of growth for the company: it added 10 widebody and 70 small- and medium-body planes during the pandemic.
Described by Boeing as one of the most “fuel-efficient” aircraft on the market, thanks to its twin-engine design, the 777 freighter forms a central part of DHL Express’ renewal plans, said Mr Pearson, adding that 28 were on order.
With 28 777 freighters on order, DHL will need a lot of SAF.
A Last Thought
Given the size of DHL’s fleet, which in their Wikipedia entry is given as 197, seventy-three of which are narrow bodies, I am surprised that no dedicated zero-carbon small or medium-sized cargo aircraft, except for the Alice is under development.
Perhaps, in areas like Europe, this niche is being taken by rail or perhaps by Airbus’s proposed hydrogen-powered ZEROe Turbofan.
I wrote in detail about this hydrogen-powered aircraft in Could An A320 neo Be Rebuilt As A ZEROe Turbofan?.
Airbus say that the passenger version of the ZEROe Turbofan could handle up to 200 passengers, despite having a large hydrogen tank in the rear fuselage.
The cargo capacity of a ZEROe Turbofan would probably be a bit smaller than say the latest Airbus A321 or Boeing 737, but if the hydrogen-powered aircraft was built to accept a stretch, I wouldn’t be surprised to find it was a viable aircraft for DHL, with a fuselage stretch!
It would surely help passengers of future hydrogen-powered aircraft, overcome their fear of an aircraft fueled by hydrogen.
The ZEROe Turbofan is quoted as having a range in excess of two thousand nautical miles, so it would have Europe and North America fairly well covered.
I also wouldn’t rule out use of Airbus’s proposed hydrogen-powered ZEROe Turboprop for flying cargo.
It would have a smaller capacity than the ZEROe Turbofan.
- It would have a useful range of over a thousand nautical miles.
- I feel that both ZEROe aircraft have the same fuselage cross-section, which could ease cargo handling, by using the same equipment for both aircraft.
- I also feel that both ZEROe aircraft will have the same cockpit, which should reduce crew costs.
I feel that smaller cargo aircraft will play a large part in the development of hydrogen-powered aircraft.
If the plans of some companies and individuals work out, hydrogen might be a better alternative financially to SAF.
No Shortcuts In Evia Aero’s Path To Being Europe’s First Green Regional Airline
The title of this post, is the same as that of this article on FutureFlight.
This is the first paragraph.
The closer you examine the task of establishing a green airline, the clearer it becomes that it does not begin and end with sourcing net zero carbon aircraft. Evia Aero is a case in point in that while the German start-up has made provisional commitments to a pair of electric aircraft developers, for now, it is more preoccupied with getting a somewhat daunting operational ecosystem in place.
The article is an interesting read and certainly follows this old joke about aviation.
If you want to make a small fortune in aviation, start with a large fortune.
The article is mainly drawn from an interview with the founder of Evia Aero; Florian Kruse and these are some of his thoughts.
On Sustainability
This paragraph talks about a truly sustainable aviation company.
First you have to be sure that you can operate as a truly sustainable aviation company,” Evia Aero founder Florian Kruse told FutureFlight. The Bremen-based venture plans to invest in photovoltaic (PV) solar energy plants at the airports it intends to serve to fulfill its commitment to being self-sufficient in green energy, which could include electricity and hydrogen fuel. The next step will be installing the required refueling and recharging facilities.
I’ll agree with that objective, but is it an affordable commitment?
On An Air Operator Certificate
This paragraph talks about an Air Operator Certificate.
Only when these tasks are well advanced, probably in 2024, will Evia Aero secure the air operator certificate it needs to launch commercial scheduled services in Europe. The company has yet to determine whether it will establish an operation from scratch or acquire an existing AOC holder.
Having seen a friend struggle to get an airline going, I wonder, if existing AOC holders will have an advantage in getting fully certified.
Why Not Start A Traditional Airline And Transition To A Green One?
This was Florian Kruse’s answer.
Some people ask us why we don’t just start operating normal [fossil-fuel-burning] aircraft today and then make a transition [to net zero],But we don’t think that works. The only way to be successful in this is to be green with everything from the start.
But by his choice of the Britten-Norman Islander, Florian is taking a conservative route with a proven small airliner, that has been flown into hundreds, if not thousands, of airfields all over Europe and the wider world.
I suspect too, that a lot of experienced Islander pilots from all over the world, will want to add these aircraft to their log book. So recruitment of top quality pilots will not be a problem!
Refuelling And Maintenance
This is said about refuelling and maintenance.
In this regard, Evia Aero’s strategy isn’t based purely on a sustainability agenda. It views the plans for refueling and maintenance as key parts of its revenue stream.
Does this mean, it will be supplying support services to other operators of zero-carbon aircraft?
It should be remembered that the business model of some companies is based heavily on a business aircraft. Will these companies change their philosophy or change the aircraft?
One company that used business jets to sell construction equipment in the past was JCB. Prospective customers would be flown to the UK for demonstrations at their test site near the factory. GEC also used to use their business jet creatively.
The Eviation Alice, which Evia Aero intend to fly, will also be available in a six-seat business configuration.
I can imagine many companies using zero-carbon business aircraft creatively and to send the right message to customers and green activists, who haven’t been friendly in the past.
Thinking about this, as I type, I think that zero-carbon business aircraft could be a significant sector of the zero-carbon aircraft market. It would also appeal to many politicians, royalty, innovative business me and women and the very rich.
In the case of King Charles, I suspect a six-seat Eviation Alice or similar based at Northolt Airport would cost less to run than the Royal Train.
Pricing
This is said on pricing.
It believes (passengers) will pay a premium to access airfields in locations across northern Europe that are not well served by road and rail links.
I’ll go with that, as many years ago, I needed to go to Stavanger for a day or so from Ipswich. So I flew Air Anglia from Norwich in a Bandeirante, rather than go from Heathrow with a change at Oslo.
Backing And Expertise
This is a paragraph from the FutureFlight article.
Evia Aero is not without expertise as it seeks to put these building blocks in place. One of its backers, Energiequelle, is involved in a business that owns and operates PV plants in Finland and Germany. Its leadership team also includes Gerd Weber, CEO of regional airline OLT, and the chair of its advisory board is Axel Trampnau, who previously ran the carrier Germania.
That seems reasonably strong.
If Energiequelle live up the mission statement on their web site, they could be particularly useful.
Hydrogen-Powered Islanders
This is said about their purchase of conversion kits for Islanders to be converted to hydrogen power.
Under current plans, the first aircraft in the Evia Aero flight will be nine-passenger Britten-Norman Islanders under a plan being advanced by Cranfield Aerospace Solutions (CAeS) to convert the piston-powered models to hydrogen propulsion. Evia Aero expects these aircraft to be ready to enter service in 2026 and has agreed to buy 15 of the conversion kits.
The Islander may have flown nearly sixty years ago, but nearly 1300 have been built and they are still being manufactured, so there should be plenty available from conversion and spare parts shouldn’t be a problem.
Cranfield Aerospace Solutions, is a spin-out of Cranfield University and the article says this about an ongoing project between CAeS and Evia Aero.
In 2022, the new airline signed a wider agreement with CAeS covering a provisional order for 10 hydrogen-powered 19-seat aircraft. The companies have not yet determined whether these would be conversions of existing aircraft or a clean-sheet design. Under the UK’s Project Fresson, CAeS is working on plans for new 19- and 75-seat zero-emissions regional airliners.
CAeS look like another serious contender in the zero-carbon airliner market.
Eviation Alice
This is said about the Eviation Alice.
Evia Aero has signed a memorandum of understanding covering provisional orders for 25 of Eviation’s nine-passenger, all-electric Alice aircraft. It expects to add the first of these to its fleet in 2028, a year after the U.S.-based manufacturer now says it aims to complete type certification, initially with the FAA.
Note.
- Alice is running two years behind the Islander.
- Certifying the Islander should be easier as it is an existing airliner.
I could see the earlier delivery and entry into service of the Islander, being used to develop the business.
Range And Routes
This is said about range and routes.
With either of these aircraft, Evia Aero will be launching its services with the equipment providing a modest payload and range. The Cranfield Islanders will be able to fly up to around 200 kilometers (109 nm), while Eviation last year reduced its range projections from 440 to 250 nm, citing the limitations of current battery technology.
Kruse accepts these limitations, while already laying plans to add subsequent 19-seat aircraft to his fleet. He showed FutureFlight route maps for both aircraft including planned destinations extending along the North Sea and Channel coasts from Denmark through Germany and the Benelux countries and into France and the UK.
- The range isn’t that long.
- It is 629 kilometres between Evia Aero’s base at Bremen and Southend.
- Schiphol is closer at 89 kilometres with Groningen at 147 kilometres.
But the interesting one is Heligoland at 139 kilometres.
Heligoland
This Google Map shows the archipelago.
Note.
- Heligoland is the island in the West.
- Düne is the island in the East.
- You can just pick out the characteristic pattern of Heligoland Airport‘s three concrete runways.
Why would anybody want to go to a rock in the North Sea?
This article on the Guardian, which is entitled Heligoland: Germany’s Hidden Gem In The North Sea, gives lots of reasons, including.
- History.
- It is a regular day trip from the German coast by ship.
- It used to be British.
- It could be at the heart of offshore wind developments.
But for German day-trippers, it’s probably the attraction of the island being duty-free.
It could be a nice little earner for an airline based in Bremen and it would be within the range of the Islanders.
A Pattern Of German Islands
This Google Map shows the German corner of the North Sea.
Note.
- The island of Heligoland at the top of the map.
- Bremen in the South-East corner of the map.
- The string of islands along the German and Dutch coasts.
- The red area marks out the most-Easterly island of Wangerooge.
This Google Map shows Wangerooge in detail.
Flugplatz Wangerooge is in the South-East corner of the map.
- It has an 850 metre asphalt runway.
- The island appears to have a sizeable beach.
- The island has a population of around 1200.
The Wikipedia entry for Wangerooge says this about the character of the island.
In order to guarantee a relaxed atmosphere, cars are prohibited on the island. The island can be reached by ship from Harlesiel, or it can be reached by plane via its airfield, regular service being offered from Harlesiel, Bremen, or Hamburg. The ferries leave at different times every day according to the tide. As on most East Frisian Islands, a small narrow gauge railway line, the Wangerooge Island Railway, connects the harbor to the main village.
The Wikipedia entry, for the Wangerooge Island Railway gives a lot of detail about what looks to be a fascinating railway, including this opening paragraph.
The single track Wangerooge Island Railway (Wangerooger Inselbahn) is an unelectrified narrow gauge railway with a track gauge of 1,000 mm (3 ft 3+3⁄8 in) located on the East Frisian island of Wangerooge off the northwestern coast of Germany. It is the most important means of transport on the island and is the only narrow gauge railway operated today by the Deutsche Bahn.
I must visit next time, I go to Hamburg.
Working towards the West the next airfield, I can find is on Langeoog, which is shown in this Google Map.
Flugplatz Langeoog is marked by the blue arrow towards the South-East corner of the map.
Working towards the West the next airfield, I can find is on Nordeney, which is shown on this Google Map.
Flughaven Nordeney is at the bottom of the map.
It has a 1000 metre runway and judging by the planes on the map, it is very busy.
Continuing West brings me to the Eastern end of the island of Juist, which is shown on this Google Map.
Flugplatz Juist is indicated the rightmost blue arrow. This extract from the Wikipedia entry, illustrates the importance of this airfield.
As of 2013, the airfield had up to 500 takeoffs and landings on weekends, the second most aircraft movements in the state of Lower Saxony, after Hannover Airport. The airfield is a critical piece of infrastructure for the island, due to ferry traffic being dependent on the tides.
The airfield was also the first on the East Frisian Islands to have a paved runway
Continuing West brings me to Borkum, which is shown on this Google Map.
Note.
Borkum Airport is in the Eastern half of the map.
- It has a 1000 metre asphalt runway.
- Borkum has a population of around 5000.
On this brief exploration of the German East Frisian Islands, I have been surprised to find five airfields; Borkum, Juist, Langeoog, Nordeney and Wangerooge.
- All seem to have asphalt or concrete runways.
- Were these runways built as part of a plan to improve transport to the islands, as it appears the tides make the ferries a bit variable?
It also appears that the islands are totally or at least partially car-free.
On one island I noticed that the taxis are horse-drawn carriages.
So does this all fit well with the philosophy of Evia Aero of flying zero-carbon aircraft?
I suspect it does.
I also think, that Evia Aero’s thinking has been influenced by recent events in the area, which I talked about in From Groningen To Leer By Train.
- To put it simply, a freighter called the Emsmoon, demolished the Freisenbrücke, which carries the Groningen and Bremen railway over the River Ems.
- Zero-carbon aircraft flying between Groningen and Bremen would be a viable and quicker and more comfortable alternative to the bus I took.
I wonder if Evia Aero are planning a service between Groningen and Bremen.
- Groningen and Bremen is 147 kilometres.
- Islanders can cruise at 240 kph.
- The service could call at the five intermediate airports.
- I would reckon, that the service would take about an hour between Groningen and Bremen.
- The aircraft would be refuelled at Groningen and Bremen.
- I am fairly certain that two planes could run an hourly service.
I also suspect that the ticketing could be run by an app and if there were no passengers wanting to get on or off at an intermediate stop, then the plane would continue to the next stop, which would save fuel. If a passenger missed a plane, there would be only a wait of an hour until the next one.
Get this right and if it proves successful, then extra services could be added, to create a true Turn-Up-And-Go air service.
Landing And Take-Off Performance
This is a paragraph from the FutureFlight article.
Both the Islander and the Alice offer short takeoff and landing performance that will allow them to get in and out via limited runways in small communities. In the case of the Islander, which has been in service for several decades, it will even be able to operate from grass landing strips.
Every little helps.
Islanders can also use sand runways, as they do at Barra.
Refueling The Islanders
This image of the hydrogen-powered Islander was clipped from the Cranfield Aerospace Solutions’ home page.
Consider.
- Many years ago, I had fun with a farmer friend moving a lot of apples in boxes, that were destined for Aspall Cyder with his forklift. The machine was powered by gas in a cylinder strapped horizontally behind the driver.
- We ran out of gas halfway through and it was a simple matter of disconnecting the bottle and connecting another.
- Drop tanks have been used in military aircraft for almost a hundred years.
- Universal Hydrogen refuels its hydrogen-powered aircraft by changing a fuel capsule.
Look at the above picture and note the two green cylinders under the wings.
- Could they be two hydrogen tanks for the aircraft?
- They appear to have some aerodynamic features. Could this reduce drag, but increase lift?
- Could they be cylinders for the hydrogen fuel?
- If they are fuel cylinders, is it possible for one or two people and/or possibly a special truck to easily swap an empty one for a full one?
Fast refuelling would allow the aircraft to work hard.
Connecting To Major Hubs
My proposed East Frisian Islands service, only connects to Groningen and Bremen on the mainland.
- Schiphol and Groningen Airports are only 93 kilometres apart.
- Bremen and Hamburg Airports are only 103 kilometres apart.
After refuelling, flying on without a change of plane to a major hub would be possible.
Channel Hops
This is said about range.
With either of these aircraft, Evia Aero will be launching its services with the equipment providing a modest payload and range. The Cranfield Islanders will be able to fly up to around 200 kilometers (109 nm), while Eviation last year reduced its range projections from 440 to 250 nm, citing the limitations of current battery technology.
The only hops, I can find less than two hundred kilometres are.
- Calais and Manston – 61 kilometres
- Calais and Lydd – 71 kilometres
- Calais and Southend – 111 kilometres
- Le Touquet and Lydd – 69 kilometres
- Le Touquet and Manston – 94 kilometres
- Le Touquet and Southend – 134 kilometres
- Ostend and Manston – 107 kilometres
- Ostend and Lydd – 138 kilometres
- Ostend and Southend – 210 kilometres
- Cherbourg and Southampton – 147 kilometres
Note.
- Manston and Southend are probably the two best British airports, as they have or will have a rail connection.
- Only Le Touquet has a railway station close to the airport on the European side.
I do suspect, that Eurostar could kill channel-hopping, by adding extra services.
Possible Markets
The methodology developed at Bremen, could probably be applied to other services around Europe and the wider world.
This is a paragraph from the FutureFlight article.
Evia Aero, which Kruse said is already in talks with as many as 30 regional airports about possible air services, is also eyeing the Nordic countries, the UK’s islands, and parts of southern Germany as target markets. Norway with its mountainous coastline seems a promising early adopter for short flights in net zero aircraft, not least because the country’s government plans to ban conventional aircraft on domestic routes from 2030.
The low noise of the electric aircraft might make them acceptable, where other aircraft have been rejected in the past.
Conclusion
T think Evia Aero plans are sound, but I do wonder whether the freighter trashing the railway got Florian Kruse and his friends thinking.
Eviation Aircraft Sheds Some Light On The Future Of Air Travel
The title of this post, is the same as that of this article on Inyerself.
This is the sub heading.
First Electric Commercial Flights Earmarked for 2027
This first paragraph outlines the article.
The future of air travel is here, and it is becoming apparent electric aircraft is taking front and center. Eviation Aircraft has designed Alice, the world’s first all-electric commuter aircraft. This nine-seater aircraft produces no emissions and is much cheaper than similarly sized jets and turboprops. Let’s explore how this revolutionary commuter plane works and what it could mean for the future of air travel.
The article is a good insight into the future of commercial flights over short distances of a few hundred miles.
Birmingham Plays The Green Card
This article in The Times today is entitled Birmingham Airport Set For Hydrogen Take-Off.
These two paragraphs introduce the article.
Birmingham Airport aims to become the first in Britain to operate commercial zero-emission hydrogen-fuelled flights — and by as early as 2025.
The ambitious goal follows the signing of a partnership with the British start-up ZeroAvia whose first trial flight of a 19-seater passenger aircraft powered by hydrogen fuel cells took place last month.
Other points from the article include.
- ZeroAvia is also working with Rotterdam Airport.
- Initially, it is likely that the hydrogen-powered aircraft will be used for cargo.
- The government wants all UK domestic flights to be zero-carbon by 2040.
- Birmingham wants to be zero-carbon by 2033.
- ZeroAvia has received upwards of £20 million of matched-taxpayer funding.
- It has some big backers and well-known airlines, who have placed orders.
These are my thoughts.
ZeroAvia’s Airliners
This paragraph from The Times article describes their first two aircraft.
ZeroAvia is retrofitting turboprops, 19-seater Dornier and in future 80-seater De Havilland Canada Dash 8-400s, with tanks of hydrogen which is converted by fuel cell stacks to energy taken to electric motors that power the propellers. The only emission is water. It is talking to potential new-entrant airframe makers to build all-new hydrogen aircraft of the future.
Note.
- The Dornier 228 is a 19-seater airliner of which over three hundred have been built.
- The de Havilland Canada Dash 8-400 is an 80-seater airliner of which over six hundred have been ordered and over 1200 of all marques of Dash 8s have been built.
Both are workhorses of the smaller airlines all over the world.
As the paragraph from The Times indicates the power system is not conventional, but then most of this new breed of small electric/hydrogen/hybrid airliners have electric propulsion. I suspect that there’s been a marked improvement in the design and efficiency of electric motors.
Electric propulsion should have a substantial noise advantage over turboprops.
ZeroAvia are also retrofitting their two chosen airliners.
This offers advantages in the certifying of the airliners. Providing the changes made to the airframe are not significant, the various certifying authorities in the UK, US and EU will allow previous certification to be carried over.
This means that ZeroAvia only have to thoroughly test and certify the powerplant and its integration into the aircraft.
One of their competitors, the Eviation Alice is a completely new airframe with battery-electric power, so I suspect this aircraft will take longer to certify.
I think ZeroAvia have used this shorter certification time to aim to get their airliners in service first.
Those that don’t win, don’t get the same fame.
Hydrogen At Birmingham Airport
Hydrogen will be needed at Birmingham Airport to refuel ZeroAvia’s airliners.
But will hydrogen also be used on the airside to power some of the heavy vehicles you see on airports.
Look at this page on the Hawaii Technology Development Corporation, which shows a Hydrogen Fuel Cell U-30 Aircraft Tow Tractor. The specification indicates, that it can tow a C-17 or a Boeing 747.
I wouldn’t be surprised to see Birmingham Airport build their own electrolyser nearby both to supply hydrogen-powered aircraft and decarbonise the airside.
To And From Birmingham Airport
Consider.
- Birmingham Airport is connected to Birmingham International station by a free AirRail Link.
- Birmingham International station has an impressive number of services, many of which are electric.
- There will be a people mover to connect to Birmingham Interchange for High Speed Two.
- Birmingham Interchange will have five trains per hour (tph) to and from London, taking under forty minutes.
- There are plans to extend the West Midlands Metro to the airport, with journeys taking thirty minutes from the City Centre.
- Birmingham Airport is at the centre of the UK’s motorway network.
Most public transport to Birmingham Airport will be zero-carbon and the percentage that is will increase.
A Green Air Bridge To Ireland
Currently the fastest services between London and Birmingham International station take a few minutes over the hour.
But after High Speed Two opens, the service will improve.
- High Speed Two will take under forty minutes.
- There will be five tph.
- High Speed Two will connect to the Elizabeth Line and the London Overground at Old Oak Common station.
- Euston station will have better connectivity to the Underground.
This diagram shows High Speed Two services.
Consider.
- Birmingham Interchange has good connections in the North.
- I can see that Birmingham Airport could start to attract lots of passengers going between the islands of Great Britain and Ireland.
- And don’t forget Cardiff, Swansea, Exeter, Isle of Man and New Quay.
- Could Birmingham-Dublin and Birmingham-Belfast be run as frequent shuttles?
- Will there be AirRail tickets between Euston and Belfast and Dublin?
I also wonder if zero-carbon travel will attract passengers?
Zero-Carbon Air Cargo At Birmingham Airport
This article on Railway Gazette is entitled Varamis Rail Launches Regular Express Light Freight Service.
These three paragraphs outline the service from Varamis Rail.
Varamis Rail has launched a 160 km/h express freight service between Glasgow and Birmingham International using a converted electric multiple-unit.
The service is targeted at express parcels and third-party delivery companies seeking next day delivery of consumer goods.
Consignments arriving at the Glasgow hub by 17.30 from Monday to Friday can reach Birmingham at 23.00, with northbound freight arriving at the Birmingham site by 23.00 reaching Glasgow at 05.30 the next morning.
I think this service would interface well with cargo planes operating overnight from Birmingham Airport.
It seems to me, that Spokes at Speke could be reborn at Birmingham.
Conclusion
Birmingham Airport seems to be positioning itself to take advantage of aviation’s new breed of planes.
Orders For The Eviation Alice Pass US$ 2 Billion
The title of this post, is the same as that of this press release from Eviation.
This is the first paragraph.
Eviation Aircraft, a manufacturer of all-electric aircraft, today announced that the order book for its world-leading nine-seater all-electric Alice airplane has passed a total value of US$ 2 billion.
$2 billion is a tidy sum and I suspect it ensures that they can now concentrate on its certification program on the way to completing Entry into Service (EIS).
It looks like the day, I will fly in an electric aircraft has come closer.
EVIA AERO Orders 25 Eviation Alice Aircraft
The title of this post, is the same as that of this article on Aviation Source.
The Wikipedia entry for the nine passenger Eviation Alice lists these orders.
- Cape Air – 75
- Deutsche Post – 12
- GlobalX Airlines – 50
The EVIA AERO order brings the total to 162.
The larger thirty passenger Heart Aerospace ES-30 is reported in Wikipedia to have 230 orders and a hundred options, with more letters of intent.
Companies, who have proposed to buy the ES-30 include Air Canada and United Airlines.
These are substantial numbers of aircraft and they convince me that one or both of these aircraft will fly fare-paying passengers before the end of the current decade.
‘It Was Wonderful’: Eviation’s Alice Electric Airplane Wins Praise After Its First Flight Test
The title of this post, is the same as that of this article on GeekWire.
The long-expected first flight of Eviation Alice has happened.
The flight was only a short one and was described like this in the article.
Alice flew for eight minutes and reached a maximum altitude of 3,500 feet before landing safely back at the airport.
There is also a video in this article on Electrek, which is entitled Watch Eviation’s All-Electric Alice Aircraft First Flight.
This is an important milestone in the history of aviation.
Aerospace Electrified By New Technology
The title of this post, is the same as of this article on the BBC.
The article is a good summary of the state of zero-carbon aviation.
Eviation Says Cape Air Will Take 75 Alice Aircraft
The title of this post, is the same as that of this article on Flight Global.
Orders in the Wikipedia entry for the Eviation Alice says this.
The first buyer for the Alice was Cape Air, a regional airline serving the Northeastern United States as well as the Caribbean. In August 2021, Deutsche Post announced that it had ordered 12 aircraft for use by DHL to transport cargo, with delivery planned from 2024. In April 2022, Eviation stated that Cape Air ordered 75 planes.
It does look like this innovative aircraft could be ready for more than just a first flight.
Applicability To The UK
I have a feeling, that we’ll see a lot of five-to-nine electric aircraft in the UK, as we have lots of islands and quite a lot of small airports.
The Alice has a range of around 500 miles, which is useful, but the take-off run of 800 metres could be a limitation on some islands.
Conclusion
I can’t wait to fly in an Alice.
The ZEROe Demonstrator Has Arrived
The title of this post, is the same as that of this press release from Airbus.
This is the introductory paragraph.
2022 marks a new and exciting phase for ZEROe – Airbus’ ambition to develop the world’s first zero-emission commercial aircraft by 2035. The multi-year demonstrator programme has officially been launched with the objective to test a variety of hydrogen technologies both on the ground and in the air.
The ZEROe demonstrator will be the first Airbus A 380 aircraft and it is shown in this Airbus visualisation.
Note.
- The four hydrogen tanks in the fuselage.
- The fifth engine mounted in a pod on the fuselage.
- There’s certainly lots of space inside the fuselage for more hydrogen tanks and test and monitoring equipment.
I have a few thoughts.
This Aircraft Will Be A Superb Demonstrator
The press release says this about the use of an A 380 as a demonstrator.
The A380 is the world’s largest and most spacious passenger jet ever built – a size that makes it ideally suited to the role of test platform.
Today, the A380 MSN1 test aircraft is earmarked for a new role: to take the lead on testing the technologies that will be vital to bringing the world’s first zero-emission aircraft to market by 2035.
“The A380 MSN1 is an excellent flight laboratory platform for new hydrogen technologies,” says Mathias Andriamisaina, Airbus ZEROe Demonstrator Leader. “It’s a safe and reliable platform that is highly versatile to test a wide range of zero-emission technologies. In addition, the platform can comfortably accommodate the large flight test instrumentation that will be needed to analyse the performance of the hydrogen in the hydrogen-propulsion system.”
Initially, I suspect the aircraft will fly as a four-engined turbofan aircraft running on standard or sustainable aviation fuel.
The performance of the hydrogen engine will be tested in all phases of operation and at different altitudes.
What Size Is The Fifth Engine?
This layout is clever.
If Airbus want to test a smaller hydrogen engine for say an Airbus A 320-sized hydrogen aircraft like the ZEROe Turbofan shown in this Airbus visualisation, they fit it to the fifth pylon.
Note.
- The fifth pylon on the ZEROe Demonstrator could be the proposed pylon for the ZEROe Turbofan.
- The ZEROe Demonstrator could probably carry a lot of hydrogen to test out the hydrogen engine over a long duration.
- The hydrogen engine could be tested out over the full flight envelop of an Airbus A 380.
I would suspect that the tests on the hydrogen engine would be some of the most comprehensive ever carried out on a new engine.
If Airbus want to test a larger hydrogen engine for say an Airbus A 350-sized hydrogen aircraft, they would probably replace one of the four main engines with the hydrogen engine.
It looks like Airbus will be able to test hydrogen engines for all sizes of plane in their current range.
What Will Happen To Current A 380s?
Consider.
- The production of the A 380 has been stopped.
- There are 251 aircraft in service.
- They appear to be a reliable and safe aircraft.
- The aircraft can run on sustainable aviation fuel.
- The oldest aircraft are only thirteen years old.
- They are still reasonably modern aircraft, that if they needed to be updated to the latest standards could probably be easily done so.
- The aircraft have a lot of volume, which can hold over 500 passengers in a typical configuration.
- The flying characteristics and structure of the aircraft is well known.
I suspect there are a lot of aircraft leasing companies, who feel these aircraft are too good to scrap, just because they are not zero-carbon.
Could Hydrogen Be Stored In The Wing Of An A 380?
Hydrogen storage will get more capable in the next few years and we will see hydrogen stored in strange places in vehicles and aircraft using the gas as a fuel.
The A 380 may well have an advantage in that its wing is relatively thick compared to that of other airliners.
- The A 380 has a wing aspect ratio of 7.53.
- The Boeing 787 has a wing aspect ratio of 11.
- Gliders have wing aspect ratios as upwards of 30.
High aspect ratios are generally more economical on fuel.
But this relatively thick wing, may make it possible to store hydrogen in the wing of an A 380.
Could There Be A Hydrogen-Powered A 380?
I suspect part of the Airbus ZEROe progam will be to investigate the possibility of converting existing A 380 aircraft into a capable hydrogen-powered aircraft.
In Could An A320 neo Be Rebuilt As A ZEROe Turbofan?, I looked at the possibility of turning an existing Airbus A 320 neo into a ZEROe Turbofan running on hydrogen.
This was my conclusion.
I very much feel that there will be a route to convert some or all of the A 320 neo aircraft to hydrogen power.
So what will a ZEROe A 380 look like if it follows the same design route as an A 320 neo to a ZEROe Turbofan?
- There would be a large hydrogen tank in the rear fuselage.
- As I explained earlier, there may be a possibility for some hydrogen to be stored in the wing.
- Both passenger decks would be shortened and perhaps be able to hold the 350-410 passengers of the Airbus A350-1000.
- The cockpit, front part of the fuselage, wings, tailplane and landing gear would be unchanged.
- The aircraft would fit existing jetways at any airport, that can handle an existing A 380.
I believe that converting an existing Airbus A380 to a hydrogen-powered aircraft is possible and the conversion falls within Barnes Wallis‘s rule of problem solving.
There is no greater thrill in life, that proving something is impossible and then showing how it can be done.
The quote comes from a BBC program, where he was interviewed by Chris Brasher, who was another for whom impossible was just a minor hurdle in the way of meeting objectives.
Could There Be A Hydrogen-Powered A 380 Freighter?
Consider.
- I think it is likely, that companies like Amazon will come under pressure over their carbon footprint, as they transport increasing numbers of packages around the world.
- In DHL Express Shapes Future For Sustainable Aviation With First Order Of All-Electric Cargo Planes From Eviation, I talk about how DHL Express have ordered twelve Eviation Alice aircraft to create a zero-carbon service. DHL must feel this would be good for their image. So would they like an intercontinental zero-carbon freighter?
- Some people worry about the air-miles on their food!
There could be a worthwhile niche market for a high capacity intercontinental zero-carbon freighter.
Because it has such a large internal volume, an Airbus A 380 might make an ideal aircraft to convert.
Conclusion
Airbus will learn a lot from the ZEROe Demonstrator.
They may even learn how to develop, a long-range hydrogen-powered zero-carbon A 380 variant that could carry four hundred passengers between Europe and Australia.
