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.
Could A Battery-Electric High Speed Two Classic-Compatible Train Be Developed?
A Battery-Electric High Speed Two Classic-Compatible Train, would not be needed for High Speed Two, as it is currently envisaged, as all lines will be electrified.
But Hitachi have already said that they are developing the Hitachi Intercity Battery Hybrid Train, which is described in this infographic.
This page on the Hitachi Rail web site gives this description of the Hybrid Battery Train.
A quick and easy application of battery technology is to install it on existing or future Hitachi intercity trains. A retrofit programme would involve removing diesel engines and replace with batteries.
Hitachi Rail’s modular design means this can be done without the need to re-engineer or rebuild the train, this ensures trains can be returned to service as quickly as possible for passengers. Adding a battery reduces fuel costs up to 30% or increase performance.
These trains will be able to enter, alight and leave non–electrified stations in battery mode reducing diesel emissions and minimising noise – helping to improve air quality and make train stations a cleaner environment for passengers.
Our battery solution complements electrification, connecting gaps and minimising potential infrastructure costs and disruption to service.
It looks to me, that Hitachi are playing an old Electrical/Electronic Engineer’s trick.
As a sixteen-year-old, I spent a Summer in a rolling mills, building replacement transistorised control units for the old electronic valve units. They had been designed, so they were plug-compatible and performed identically.
It appears, that Hitachi’s battery supplier; Hyperdrive Innovation of Sunderland has just designed a battery pack, that appears to the train to be a diesel engine.
In the Technical Outline, this is said.
- Train Configuration: 5 – 12 car
- Nominal Vehicle Length: 26m
- Power Supply: Battery
The AT-300 trains generally have twenty-six metre cars.
In How Much Power Is Needed To Run A Train At 125 Or 100 mph?, I calculated that a Class 801 train uses 3.42 kWh per vehicle mile, at 125 mph.
- This means that a five-car train will use 1710 kWh to do 100 miles at 125 mph.
- The train has three diesel engines, so three batteries of 570 kWh would be needed.
- Alternatively, if a battery was put in each car, 342 kWh batteries would be needed.
- In the Wikipedia entry for battery-electric multiple unit, there are two examples of trains with 360 kWh batteries.
I believe building 570 kWh batteries for fitting under the train is possible.
What would be the maximum range for this train at 100 mph?
- I will assume that five batteries are fitted.
- As drag is proportional to the square of the speed, I’ll use a figure of 2.07 kWh per vehicle mile, at 100 mph.
This is a table of ranges with different size batteries in all cars.
- 50 kWh – 24.1 miles
- 100 kWh – 48.3 miles
- 200 kWh – 96.6 miles
- 300 kWh – 145 miles
- 400 kWh – 193.2 miles
- 500 kWh – 241.5 miles
They are certainly useful ranges.
LNER Will Be Ordering Ten New Bi-Mode Trains
In LNER Seeks 10 More Bi-Modes, I discussed LNER’s need for ten new bi-mode trains, which started like this.
The title of this post, is the same as that of an article in the December 2020 Edition of Modern Railways.
This is the opening paragraph.
LNER has launched the procurement of at least 10 new trains to supplement its Azuma fleet on East Coast Main Line services.
Some other points from the article.
- It appears that LNER would like to eliminate diesel traction if possible.
- On-board energy storage is mentioned.
- No form of power appears to be ruled out, including hydrogen.
- LNER have all 65 of their Azumas in service.
I believe that ten trains would be enough to handle LNER’s services on lines without electrification to the North of Scotland.
- London and Aberdeen has 130 miles without wires.
- London and Inverness has 146 miles without wires.
- Electrification plans are progressing North to Perth and to Thornton Junction.
I suspect both routes could be upgraded to under a hundred miles without wires.
I believe, that if Hyperdrive Innovation pull out every trick in the book to save power in their batteries that a five-car Azuma with a 300 kWh battery in each car, will have sufficient range with reserves to go between Edinburgh and Inverness or Aberdeen at 100 mph.
A Battery-Electric High Speed Two Classic-Compatible Train
Consider.
- I am a great believer in regenerative breaking to batteries on the train, as my experience says it the most efficient and also gives advantages, when the catenary fails.
- Stadler’s approach with the Class 777 train, where all trains have a small battery for depot movements, is likely to be increasingly copied by other train manufacturers.
- Hitachi have also designed the Class 803 trains for Lumo with emergency batteries for hotel power.
I could envisage provision for batteries being designed into a High Speed Two Classic-Compatible Train.
Suppose it was wanted to run High Speed Two Classic-Compatible Trains between Crewe and Holyhead.
- The train has eight cars.
- The route is 105.5 miles.
- I will assume an average speed of 100 mph.
- A Class 801 train uses 3.42 kWh per vehicle mile, at 125 mph.
- As drag is proportional to the square of the speed, I’ll use a figure of 2.07 kWh per vehicle mile, at 100 mph.
- This means that an eight-car train will use 1747.08 kWh to do 105.5 miles at 100 mph.
- I would put a traction battery in each car, to distribute the weight easily.
Each battery would need to be 218.4 kWh, which is totally feasible.
How far would the train travel on 300 kWh batteries at 100 mph?
- Total battery capacity is 2400 kWh.
- One mile will use 16.56 kWh.
- I am assuming the train is using regenerative braking to the battery at each stop.
The train will travel 145 miles before needing a recharge.
On the Crewe and Holyhead route, there would be a reserve of around 40 miles or nearly 500 kWh.
Conclusion
I am convinced that Hitachi and their highly regarded partner; Hyperdrive Innovation, have developed a battery pack, that gives enough power to match the performance of Class 800/802/805/810 trains on diesel and give a range of upwards of a hundred miles on battery power at 100 mph, if you put a 300 kWh battery pack in all cars.
- But then Stadler have run an Akku for 115 miles and a Class 777 for 84 miles on battery power alone.
- I think the key is to put a battery in each car and harvest all the electricity you can from braking.
- Remember too that Hitachi can raise and lower their pantographs with all the alacrity of a whore’s drawers, so strategic lengths of overhead electrification can also be erected.
Hitachi and Hyperdrive Innovation appear to have invented the High Speed Battery Train.
We’ll know soon, when the order for the LNER bi-modes is announced.
Whatever works on LNER, should work on High Speed Two.
A Rare Site – Two 141 Buses
I took this picture, this afternoon of a rare site these days – two 141 buses running in convoy.
Nothing seems to be improving and passengers are regularly waiting 15-20 minutes for a 141 bus, when the timetable says it should be 4-8 minutes.
World’s First Offshore Vessel Charging System Completes Harbour Trials
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
MJR Power and Automation, together with Blackfish Engineering and Tidal Transit, have completed the harbour trials of the company’s platform-mounted automated offshore power and charging system.
Reading the article, this appears to be a very comprehensive system, that allows electric or hybrid wind farm servicing vessels to top up their batteries efficiently before returning to base.
Surely, it is better to do it this way by developing the charging network before bringing the battery and hybrid vessels into service.
On The Loose In North London: Flying Gazebo Causes Train Delays
The title of this post, is the same as that of this news item on Network Rail.
These paragraphs outline the story.
Residents are being urged to keep garden objects tied down and away from the railway after a flying gazebo caused 60 trains to be delayed or cancelled on Friday.
Passengers on London Overground trains running between Gospel Oak and Barking experienced disruption for around three hours. Freight trains were also affected.
The gazebo was reported to be blocking the line between Upper Holloway and Crouch Hill stations at around 0945 and trains had to be stopped while it was recovered by a Network Rail response unit.
In total, the incident caused 15 full train cancellations, 8 part cancellations and delays to 37 trains.
There is also this picture of the remains of the errant gazebo.
At least it appears, that the gazebo didn’t bring the wires down.
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.
Should There Be Five-Car High Speed Two Classic-Compatible Trains?
The High Speed Two Classic-Compatible Trains have the following characteristics.
- Eight cars.
- 200 metres long.
- 550 passengers.
- Two can be coupled together to make a 16-car train, that is 400 metres long.
- Trains can join and split en route.
This graphic shows the preliminary schedule.
Note that Train 4, starts as a pair of trains, before splitting at Crewe, with one train going to Lancaster and the other to Liverpool Lime Street.
I wonder, if some trains were to be five-cars, would this give the operator more flexibility, by allowing three trains to be coupled together to serve three destinations.
This could be a simple example.
- A three train formation could leave Euston.
- At Crewe one train would detach and go to Liverpool Lime Street, with stops at Runcorn and Liverpool South Parkway.
- At Preston, the two remaining trains would split, with one train going to Lancaster and the other going to Blackpool with appropriate stops.
Three trains might give the operators more flexibility in providing appropriate capacity to various destinations.
Other Applications
I believe these trains would have other applications.
These are a few thoughts.
Battery-Electric High Speed Train
Battery technology is improving and I believe that a train could be designed with the following specification.
- Five cars
- High-Speed Two Classic-Compatible performance.
- A battery pack in each car.
- Up to maximum operating speed of digitally-signalled high speed lines.
- 140 mph on digitally-signalled classic high speed lines, like the East and West Coast Main Lines. the Midland Main Line and the Great Western Railway.
- Range on battery of around 120 miles at 100 mph.
- Ability to work with fully-electric versions.
Note.
- I suspect that like current Hitachi AT-300s and Bombardier Aventras, the onboard computer would know what cars have been coupled together and what the train can do.
- A battery in each car would distribute the extra weight of the batteries equally and not affect the handling too much.
- These trains would allow High Speed Two services to be extended onto non-electrified lines.
I suspect that an eight car battery-electric High-Speed Two Classic-Compatible train would also be possible for working with the standard length trains.
Hydrogen Truck Can Make Garbage Day A Much Quieter Event
The title of this post in the same as that of this article on Hydrogen Fuel News.
This is the first paragraph.
Hyzon Motors has announced that it will be rolling out a 27-ton Australian-made hydrogen truck to be used for vehicle towing as well as potentially for garbage collection this year.
Less noise, less pollution\2 What more can you want?
In London, we something rather important, a hydrogen policy, rather than a Mayor, who hopes the problem will fade away.
The writer of this article finds it interesting, that Hyson, who are an American company are making the trucks in Australia.
They say this.
Hyzon opened an Australian location three years ago in order to benefit from the substantial industry talent that became available there when Ford, Toyota and Holden closed their local operations. As the country also places a considerable focus on H2 production, it has opened several doors for moving forward with various types of hydrogen truck design.
So vehicle manufacturers beware! If you close an operation in a country, you may find competitors starting up!
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.
