Offshore Drone Challenge Takes Off
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
German energy company EnBW and its project partner, the German Aerospace Center (DLR), have published the conditions of entry and the specific flight tasks for the Offshore Drone Challenge (ODC) for the first time.
This is the first paragraph.
As part of the Offshore Drone Challenge, drone manufacturers and service providers are invited to demonstrate their technologies for transporting maintenance equipment to offshore wind farms.
It’s an interesting idea and would make a good television program.
But I suspect, that the winner will be a Ukrainian company, as recently, they’ve had a lot of practice delivering cargoes with a high level of precision into confined and difficult places.
Ricardo – The Role Of Hydrogen In The Green Aviation Revolution
The title of this post, is the same as that of this article on Hydrogen Central.
This is the third paragraph.
The introduction of zero-emission aircraft will enable us to re-think our approach to regional connectivity and the way we currently fly. A recent report by Project NAPKIN stated that zero-carbon emission flight is entirely possible from the middle of this decade on sub-regional routes, on aircraft ranging in size from seven to 19 seats.
It makes a bold statement.
The article is a must read.
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.
Scottish Hydrogen Fuel Tank – SHyFT
The title of this post, is the same as that of this page on the Innovatus Technologies web site.
This is the sub-heading.
Advanced Flexible Form Factor and Lightweight Multi-Chamber Type IV & V Hydrogen Storage Vessel
These paragraphs outline the product.
SHyFT is a unique Type IV or V composite high-pressure vessel unlike conventional large, heavyweight cylindrical vessels. The unique multi-chamber composite design, aided by patented composite technology and recyclable materials, allows for SHyFT to conform to any form factor specific to our customers needs.
SHyFT’s largest model boasts the worlds highest Gravimetric Storage Density of 10%, allowing 5.4 KG of hydrogen storage. This is a significant 10% increase on current market leaders in composite storage of gaseous substances.
The core composite technology drives a 25%+ weight and 20%+ cost reduction, whilst providing superior quality and technical performance for a more efficient and economical product. With SHyFT, various market applications such as commercial, personal and industrial transport, Marine and UAV, can be easily dominated creating a higher value proposition for our customers.
As with other companies in the past, like Pilkingtons, Rolls-Royce and Skeleton Technologies, who have developed a unique product, I suspect that the key is a special purpose machine that makes the tanks. I have two friends in Cambridge, who specialise in making unusual manufacturing machines and they are very busy.
I first came across this company as they are named in the Wikipedia entry for Project Fresson, which is a part-Scottish project to create a hydrogen-powered Islander aircraft.
Innovatus Technologies are building the composite hydrogen fuel tanks. Two, which are coloured green, appear to be mounted below the wings and there could be others inside the fuselage.
This company could solve one the major problems with hydrogen applications – How to cram in enough of the gas to make the application possible!
Conclusion
I predict a big future for this company, unless the Chinese or other idea-stealers ruin the market.
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.
Universal Hydrogen Successfully Completes First Flight Of Hydrogen Regional Airliner
The title of this post, is the same as that of this article on Hydrogen Central.
These two paragraphs outline the story.
Universal Hydrogen successfully completes first flight of hydrogen regional airliner.
Universal Hydrogen Co., this morning flew a 40-passenger regional airliner using hydrogen fuel cell propulsion. The airplane, nicknamed Lightning McClean, took off at 8:41am PST from Grant County International Airport (KMWH) and flew for 15 minutes, reaching an altitude of 3,500 MSL. The flight, conducted under an FAA Special Airworthiness Certificate, was the first in a two-year flight test campaign expected to culminate in 2025 with entry into passenger service of ATR 72 regional aircraft converted to run on hydrogen.
Other details from the article include.
- Connect Airlines are the North American launch customer, who have ordered 75 aircraft conversions.
- Amelia are the European launch customer.
- Universal Hydrogen has an order book, totaling 247 aircraft conversions from 16 customers worldwide.
- For the test flight, only one engine was replaced by a hydrogen fuel cell powered electric motor.
- Deliveries will start in 2025.
The article finishes with two paragraphs about Universal Hydrogen.
Universal Hydrogen is building a hydrogen logistics network to fuel the future of aviation, today. Hydrogen is the ideal fuel for flight and will power aviation’s new golden age, where planes are powered by renewables and emit nothing but water. The company’s modular hydrogen capsules move over the existing freight network from production directly to the airplane anywhere in the world.
Universal Hydrogen is also working to certify a powertrain conversion kit to retrofit existing regional aircraft to fly on hydrogen. The company has gathered the world’s leading aviation and hydrogen talent to give the industry the option of clean flight, forever.
The company also has an unusual web site.
I like the company and its design, operating and marketing philosophies.
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.
Preparing For Take-Off: Aviation Embraces Clean Hydrogen
The title of this post, is the same as that, of this article on Ryse Hydrogen.
These three paragraphs introduce the article.
Aviation’s clean hydrogen revolution is coming from all directions.
Taking a bottom-up approach, start-ups such as ZeroAvia are developing technology to convert small aircraft to hydrogen fuel, while at the other end of the spectrum, industry giants such as Airbus and Rolls-Royce are exploring how they can carry hundreds of passengers 1,000s of miles across the world.
The timescales for these projects are very different but progress is visible for both approaches.
The last two paragraphs are optimistic.
Hydrogen fuel could make up 32% of the market by 2050 if it becomes commercially available by 2035, according to a study from climate think-tank Energy Transition Commission.
It would seem that it’s only a matter of time before truly clean air travel is cleared for take-off and hydrogen-powered aircraft are carrying passengers and cargo across the skies.
The article is a good summary of the state of zero-carbon hydrogen-powered aircraft. Read it!
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.
Swedish Battery-Electric Aircraft Selected By A Major Airline
The title of this post, is the same as that of this article on autoevolution.
This is the sub-heading.
You know that saying, “New year, new me”? In the case of this major airline, it’s more like “New decade, new me.” Air New Zealand wants to flaunt a brand-new regional fleet starting 2030. And it looks like that will include an all-electric model developed by the Sweden-based Heart Aerospace.
The article then gives a description of their plan called Mission Next Gen Aircraft to go zero-carbon on their short haul routes.
This paragraph describes the aircraft that will be used.
ATR will bring its upgraded aircraft concept, called the ATR EVO, designed to be 100% compatible with SAF (sustainable aviation fuel). Embraer will showcase the innovations of an entire new family of aircraft named Energia, based on various types of clean propulsion. Universal Hydrogen will retrofit the existing regional airliners with its efficient hydrogen solution. Last but not least, Heart Aerospace will focus on the niche segment of battery-electric aircraft.
It will be fascinating to see how all this works out.
We’re still waiting in the UK for an airline to announce the purchase of a zero-carbon aircraft.
Especially, as we have some routes, like those around Scottish islands, where there are many short routes, that have less than a dozen passengers on a flight.
