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.
Hydrogen-Powered Aircraft Offer Fresh Perspective For Sustainable Travel
The title of this post, is the same as that of this article on The Engineer.
The article puts forward the view of Jenny Kavanagh, Chief Strategy Officer, Cranfield Aerospace Solutions.
They are developing Project Fresson, which appears to have switched from electric to hydrogen propulsion. In the article Jenny Kavanagh says it is showing more promise and in the Wikipedia entry for Project Fresson, there is a section on hydrogen power, which details the switch.
As the article in The Engineer and the Wikipedia entry for Project Fresson seem to agree, I would assume that that the Wikipedia entry is being updated.
Budget 2021: Rishi Sunak Defends Lowering Domestic Air Duty
The title of this post, is the same as that of this article on the BBC.
These are the first two paragraphs.
The chancellor has said his Budget – including tax cuts to air tax – will help the government meet its net zero carbon targets.
Rishi Sunak used his Budget to slash taxes on domestic flights, which is forecast to lead to 400,000 extra air journeys a year.
I think he could have gone further.
It is my belief that the first area of aviation to decarbonise will be the short-haul sector.
We are seeing electric aircraft being developed like the Cessna Electric Caravan, Eviation Alice and Project Fresson.
Perhaps, domestic flights in true zero-carbon aircraft like these should be free of Air Passenger Duty?
It might even speed their introduction.
Rolls-Royce And Tecnam Join Forces With Widerøe To Deliver An All-Electric Passenger Aircraft Ready For Service In 2026
The title of this post, is the same as that of this press release from Rolls-Royce.
This is the first paragraph.
Rolls-Royce and airframer Tecnam are joining forces with Widerøe – the largest regional airline in Scandinavia, to deliver an all-electric passenger aircraft for the commuter market, ready for revenue service in 2026. The project expands on the successful research programme between Rolls-Royce and Widerøe on sustainable aviation and the existing partnership between Rolls-Royce and Tecnam on powering the all-electric P-Volt aircraft.
This picture from Rolls-Royce shows the proposed aircraft.
The P-Volt aircraft is based on the Tecnam P2012 Traveller.
The specification of this aircraft is as follows.
- Crew – 1 or 2
- Capacity – 9 passengers
- Powerplant – 2 x 280 jW piston engines.
- Cruise speed – 200 mph
- Range – 1090 miles
- Service ceiling – 19,500 ft.
The aim is to have an aircraft in service by 2026.
Use By Widerøe
This paragraph from the press release, outlines Widerøe‘s planned use of the aircraft.
The collaboration offers an opportunity to develop an exciting solution to the commuter aircraft market. Before the pandemic, Widerøe offered around 400 flights per day using a network of 44 airports, where 74% of the flights have distances less than 275 km. The shortest flight durations are between seven and fifteen minutes. Developing all-electric aircraft will enable people to be connected in a sustainable way and will fulfill Wideroe’s ambition to make its first all-electric flight by 2026. The all-electric P-Volt aircraft, which is based on the 11-seat Tecnam P2012 Traveller aircraft is ideal for the short take-off and landing as well as for routes in the North and the West Coast of Norway.
Conclusion
There are now five electric or low-carbon aircraft in the sub-nineteen passenger segment.
- The Cessna eCaravan, which I wrote about in Watch First Electric Caravan Fly.
- The Eviation Alice, which I wrote about in Orders For A New All-Electric Airplane Now Top 150.
- The Faradair BEHA, which I wrote about in Faradair’s BEHA Hybrid Aircraft Boosted By Partnerships.
- Project Fresson, which is an electric version of a Britten-Norman Islander.
Note.
- The Slice and the Faradair are new designs.
- The Faradair is hybrid and all the others are fully electric.
- The Faradair can carry eighteen passengers and all the others are smaller.
- I suspect there are others under development.
Conclusion
The Tecnam P-Volt must have a high chance of success.
- It’s designed for a purpose in a particular airline.
- The Widerøe model would apply to large number of small feeder and commuter airlines.
- Rolls-Royce are well-respected in aviation.
- An existing airframe is being used, which shortens certification.
- Norway is not short of a few bob.
- Cape Air have ordered 93 of the piston engined variant.
I will look forward to flying this aircraft.
Watch First Electric Caravan Fly
The title of this post, is the same as that of this article on AOPA.
As AOPA is the Aircraft Owners And Pilots Association, the caravan is a Cessna C208B Grand Caravan, which has been converted to electric power.
I have flown in a Cessna Caravan in Kenya, where it took me from Nairobi Airport to the Maasai Mara.
It is a typical workhorse all over the world carrying up to nine or thirteen passengers or freight.
- They have a single turboprop engine.
- The undercarriage is fixed and very sturdy.
- Around 2,600 had been built by 2017.
- It is used by a variety of operators.
I would certainly be happy to fly in one at any time, unlike some aircraft I could mention.
This paragraph from the article details how the maker of the electric motor;magniX is involved in electric flight.
The Grand Caravan is to be the largest, but not the first commercial aircraft magniX has converted to fly with 100 percent electric power. Roei Ganzarski, CEO of magniX, wrote in an email exchange that the de Havilland DHC–2 Beaver first flown in December continues its test flight program in Canada. Harbour Air, a short-haul air carrier with a fleet of seaplanes, is working with magniX to convert its fleet to all-electric power, and the same 750-hp electric motor that will power the upcoming Grand Caravan flight has been performing well in test flights over British Columbia.
Ganzarski is quoted as saying he is pleased with results to date.
The aircraft is lined up to make its first flight on May 28th, which hopefully will be shown on the Internet.
My flight in Kenya was only about half-an-hour and despite the Caravan having a range of nearly 2,000 kilometres, I suspect that many flights in the aircraft are of similar duration.
A Quick Battery Size Estimate
- 750 hp is 560 kW.
- So a half-hour flight on full power will use 280 kWh plus whatever is needed for aircraft systems like avionics, heating and air conditioning.
- The Eviation Alice electric aircraft seats nine passengers and has a 900 kWh battery according to Wikipedia.
I would suspect a 900 kWh battery should allow the Electric Caravan to do two half-hour trips.
The Future Of Electric Aviation
It is interesting to note, that four of the projects in designing and building a viable electric aircraft are in this nine-seater segment.
- Eviation Alice, which is a new radical aircraft with three magniX electric motors.
- Harbour Air Seaplanes‘s conversion of a DHC-2 Beaver seaplane using a magniX motor.
- magniX’s conversion of a Cessna Caravan, described in this post.
- Cranfield University‘s conversion of a Britten-Norman BN-2 Islander in Project Fresson.
Note.
- All except Eviation Alice, are conversions of proven high-wing aircraft with a fixed undercarriage.
- Moderately large fleets available for conversion. – Beaver (1,600 plus built), Caravan (2,600) and Islander (700)
- Conversion only needs a Supplemental Type Certificate, rather than full certification.
- The DHC-2 Beaver prototype first flew on the day I was born, so it can’t be all bad.
A detailed insight into the reasons and the economics of converting an existing fleet of aircraft are given in a sub-section called Development in the Wikipedia entry for Project Fresson.
- Scottish Airline Loganair appears to be the launch airline and will use the plane for their short flights around Orkney.
- Several companies are involved in the development.
- First flight is aimed for 2021.
- Conversion kits could be available in 2022-2023.
- It is hoped that operators would get a return on their money for the kit in 2-3 years.
Once they get the design right, there is talk of a nineteen-seat electric airliner.
I can see hundreds of converted electric Caravans and Islanders flying short routes by 2030.
The Anonymous Widower
