Could An A320 neo Be Rebuilt As A ZEROe Turbofan?
This post is a follow-up to ZEROe – Towards The World’s First Zero-Emission Commercial Aircraft.
I spent a lot of time yesterday, looking at YouTube videos of the following.
- Airbus A320 aircraft
- Airbus A 320 neo aircraft
- Airbus’s proposed ZEROe Turbofan aircraft
I also captured these profiles from the Airbus web site, of three members of the new Airbus A 320 neo family and the current Airbus A 320 ceo.
A 319 neo – Length – 33.84 metres – Max Passengers – 160
A 320 neo – Length 37.57 metres – Max Passengers – 194
A 321 neo – Length 44.51 metres – Max Passengers – 244
A 320 ceo – Length 37.57 – Max Passengers – 180
Note.
- The links on each variant lead to Airbus’s on-line specification.
- All three variants have a wing-span of 35.8 metres and a height of 11.76 metres.
- All variants have sharklets or blended winglets to improve awrodynamic efficiency.
- There are different door, cargo door and window layouts on all three variants.
- The cockpits, tail and wings look similar.
This capture from an Airbus video, shows the profile of the proposed ZEROe Turbofan.
Note, that the ZEROe Turbofan looks more streamlined than the A 320 neo family, with a redesigned nose and more swept-back tailfin and sharklets.
These are my thoughts on the current A 320 neo family and their relationship with the ZEROe Turbofan.
Focus On Commonality
For each variant on the Airbus web site, there is a section with this title. This is the first sentence for the A 320 neo.
Due to its 95 per cent airframe commonality with the A320ceo (current engine option) version, Airbus’ A320neo jetliner fits seamlessly into existing A320 Family fleets worldwide – which is a key factor for the company’s customers and operators.
Will Airbus follow this philosophy with the ZEROe Turbofan?
If it worked between the changeover between the existing A 320 fleets and the A 320 neo fleets, why change the policy?
The Cockpits
The cockpits of the A 320 neo and the A 320 ceo seem to have a similar profile, but the cockpit of the ZEROe Turbofan seems to have been reprofiled.
In ZEROe – Towards The World’s First Zero-Emission Commercial Aircraft, I showed these front on views of the cockpits of the ZEROe Turboprop and ZEROe Turbofan.
I questioned if the two cockpits were related.
- A single cockpit for both aircraft would surely ease manufacture, maintenance and pilot training.
- I’m no aerodynamicist, but it certainly looks that the new cockpit will reduce drag and fuel consumption.
Although the cockpit, appears to be being used in the ZEROe for the first time, I would expect it is already under development and might feature in any later version of the A 320 neo.
The Fuselages
The fuselage width for both the A 320 neo family and the A 320 ceo are all 3.95 metres, with a maximum cabin width of 3.70 metres.
I would expect that the ZEROe Turboprop and the ZEROe Turbofan will also use this width.
Airbus use a design called Cabin-Flex to get the most out of the interior space in the A 320 neo. This paragraph is from the Wikipedia section, that is entitled Cabin-Flex.
By permanently replacing the second door pair in front of the wing (R2/L2) with a new second pair of overwing exits, the capacity of the A321neo is increased from 220 seats to 240 seats and fuel efficiency per seat is increased by 6%, exceeding 20% together with the new engines and the sharklets. The modifications should weigh 100 kg more.[82] Initial A321neos have the A321ceo exit door configuration with four exit door pairs until the Airbus Cabin-Flex (ACF) layout can be selected.
After reading the whole section, it looks to me, that the A 320 neo fuselage is designed, to be all things to all airlines and doors and seats can be arranged to fit any requirements.
In the ZEROe Turbofan, there is a large liquid hydrogen tank behind the rear pressure bulkhead, which could be brought forward a bit to give more space and hydrogen capacity.
I suspect there will be a lot of commonality between the fuselage of the A 320 neo family and that of a ZEROe Turbofan.
I spent a lot of time, as a child building Airfix models of aircraft and it may be too much of a simplification to think of these carbon-composite airliners, as giant Airfix models.
But I wouldn’t be surprised that just like the previous generation of aluminium airliners, they can be remanufactured into something different, just like British Airways Tristars, ended up as tanker-aircraft for the RAF.
I wouldn’t be surprised to find, that later A 320 neo fuselages will be able to be remanufactured into fuselages for ZEROe Turbofans.
Comparing The Fuselages Of The A 320 ceo, A 320 neo And ZEROe Turbofan
These are the three fuselage profiles.
A 320 ceo
A 320 neo
ZEROe Turbofan
Aircraft balance on the wings, which if I remember what little I know about aircraft aerodynamics and design, apply their lift forces to the centre of gravity of the aircraft.
I know that the profile of the ZEROe is to a different scale, but three things are apparent.
- The windows at the rear don’t go as far back, as they do in the two existing designs. But then there is no need for windows around the hydrogen tank.
- The hydrogen tank could be as long as a quarter of the length of the fuselage.
- The front section of the aircraft appears longer.
The longer front section would balance the weight of the hydrogen tank.
The passengers would also help to balance the weight of the tank, by being placed further forward.
There must be the possibility of creating a larger capacity and longer range variant of the ZEROe design, by adding a larger hydrogen tank and further stretching the nose.
Airbus have been stretching these designs for years, so I suspect that they have plans for a large number of possible variants of the ZEROe Turbofan.
According to the Wikipedia entry for the A 320 neo family, there are already five civil versions of the A 320 neo; A 319 neo, A 320 neo, A 321 neo, A 321LR and A 321XLR, plus corporate and military versions.
Add in the Cabin-Flex interior and the various A320s and the ZEROe to come, must be one of the most flexible transport systems in history.
The Tailplanes
As they are of the same height and look similar, the tail sections of the A 320 neo and A 320 ceo families could be almost identical, but the tail section of the ZEROe Turbofan appears to be slightly more swept-back and perhaps more aerodynamic.
As the ZEROe Turbofan, also appears to have had a nose-job, I would suspect that Airbus have a redesigned fuselage in the works to squeeze more fuel-efficiency out of this family of already very frugal aircraft. Could this feature the more aerodynamic tailplane?
Could this advanced fuselage feature in a later version of the A 320 neo?
I also feel, that the functionality of the tailplane on the ZEROe Turbofan will need to be little different to that on the earlier planes.
- The plane is still powered by two turbofan engines on the wings.
- Rudder forces, with an engine failure on one side, will still be the same.
The big difference will be that the fuel is at the back of the fuselage rather than in the wings, which will affect the balance.
Will this effect the design of the tailplane? I don’t think it will in a large way, as Airbus seem to have lengthened the nose to compensate.
The Wings
All the wings with sharklets for the A 320 neo family and the A 320 ceo have the same wingspan of 35.8 metres, so I would expect they are all substantially similar.
But there is one big difference in that the wings of the conventionally-powered aircraft are full of fuel.
This would probably mean that much of the wing stresses in the ZEROe Turbofan would be like an A 320 neo flying with little fuel in the wing tanks. As some aircraft in the A320 neo family have fuselage tanks, Airbus can even test the wing forces and handling in a real aircraft.
But it does look that Airbus will have little trouble designing, building and certifying the wing of a ZEROe Turbofan.
There is a minor difference in that the sharklets for the ZEROe Turbofan are more extreme.
But then as I said earlier, is there a new more aerodynamic airframe for the A 320 neo in the works?
Conclusion
I very much feel that there will be a route to convert some or all of the A 320 neo aircraft to hydrogen power.
New Four Stroke Engine: Turning Hydrogen Sceptics Into Believers
The title of this post, is the same as that of this article on Riviera Maritime Media.
This is the introductory paragraph.
A new medium-speed, dual-fuel engine will underpin the use of hydrogen as fuel for coastal shipping and cold ironing applications.
Coastal shipping I understand, but what is cold ironing?
Thank heaven for this Wikipedia entry, which has this introduction.
Cold ironing, or shore connection, shore-to-ship power (SSP) or alternative maritime power (AMP), is the process of providing shoreside electrical power to a ship at berth while its main and auxiliary engines are turned off.
The article says this under a heading of Cleaner Cold Ironing.
Mr Saverys believes ports can also benefit from using Behydro engines for cold ironing applications: “We actually think that a mobile electricity solution along the quay is much, much cheaper and more flexible than pulling electricity cables at every single terminal.”
He envisages the mobile solution as either land-based or barge-based: “More and more, we have to go to zero emissions in port. In Rotterdam, Hamburg and Antwerp, we realised we should look at a more flexible and cheaper solution.”
The article also says that the dual fuel (hydrogen and diesel) engines have marine, rail and power generation applications and they can build engines up to 10 MW.
Next Stop Hydrogen For New Rail Project
The title of this post, is the same as that of this article on Business Green.
This is the introductory paragraph.
Three British companies unite to develop new hydrogen fuelling infrastructure that could soon allow for the roll out of zero emission trains on the UK rail network.
Some points from the article.
- The three companies involved are Fuel Cell Systems Ltd, tpgroup, and Vanguard Sustainable Transport Solutions.
- Their initial focus will be on the rail industry.
It looks to be a good start to provide much-needed infrastructure.
Scunthorpe Steelworks
On my way back from Cleethorpes, I passed Scunthorpe Steelworks.
It did seem rather quiet, although I did pass a train-load of new rails on their way to somewhere.
The Future Of Steel-Making
Steel-Making is on its uppers in the UK and it has a bad carbon footprint.
However, various processes are in development that could make the industry fit for the Twenty-First Century.
HIsarna Steelmaking
In Whitehaven Deep Coal Mine Plan Moves Step Closer, I said this.
In Wikipedia, there is an entry for the HIsarna ironmaking process.
This process is being developed by the Ultra-Low Carbon Dioxide Steelmaking (ULCOS) consortium, which includes Tata Steel and the Rio Tinto Group. Reduction in carbon-dioxide produced by the process compared to traditional steel-making are claimed to be as high as fifty percent.
This figure does not include carbon-capture to reduce the carbon-dioxide still further.
However, looking at descriptions of the process, I feel that applying carbon-capture to the HIsarna steelmaking process might be a lot easier, than with traditional steelmaking.
As Scunthorpe is close to Theddlethorpe Gas Terminal, the captured carbon-dioxide could probably be stored in wells connected to the terminal.
Hydrogen Steelmaking
North-East Lincolnshire is becoming the new Aberdeen, but instead of being based solely on oil and gas, there is a large proportion of wind energy being reaped.
In the future, I believe that a lot of this wind energy will be turned into hydrogen gas both onshore and increasing off-shore scores of miles out in the North Sea. There is talk of upwards of 70 GW of wind turbines being installed and much of it will be turned into hydrogen in North-East Lincolnshire.
In Funding Award to Supply An 8MW Electrolyser, I wrote about hydrogen steelmaking and the HYBRIT process in particular.
Will some of this massive amount of hydrogen be piped to Scunthorpe to make steel?
Conclusion
The future of steelmaking in Scunthorpe, doesn’t have to be all doom and gloom.
Green Tugboats? ‘Revolutionary’ Hydrogen Ship Engine Unveiled In Belgium
The title of this post, is the same as that of this article on Business Green.
This is the first paragraph.
A “revolutionary” hybrid ship engine powered by green hydrogen and diesel has been unveiled today in Belgium, with developers claiming the innovation could cut CO2 emissions from ships, trains and electricity generators by up to 85 per cent.
The engine has been given the name BeHydro.
The first order has been received by the developers; ABC, for two 2MW dual fuel engines that will be installed on a hydrogen-powered tug for the Port of Antwerp.
Motors up to the size of 10 MW are under development.
This is the last sentence of the article.
In theory, any large diesel engine can be replaced by a BeHydro engine. The hydrogen future starts today.
It is a quote from the CEO of one of the companies involved.
Conclusion
This is a development to follow.
The BeHydro engine, with its dual-fuel approach, is claimed to cut carbon emissions by 85 %.
In the Wikipedia entry for ABC or Anglo Belgian Corporation, there is a section called Products. This is a paragraph.
The engines are found in use on large river barges such as those found on the Rhine, coastal freighters, fishing boats, ferries, tugboats (which typically use 2 engines), and other ships. Other applications include electricity generation, and pumping engines, engines for cranes, and locomotives (including the Belgian Railways Class 77 and Voith Maxima), as well as dual fuel (gas/oil) DZD engines.
I feel that that the BeHydro engine will keep the company busy.
Four Must-Read Articles From H2-View
I have just read these articles on H2-View.
- New partnership aims to convert Dash 8 airliner to hydrogen fuel
- 1,000 new hydrogen-powered buses planned for European roads
- Investing in hydrogen trains will put UK green recovery on the fast track
- Mercedes-Benz GenH2 Truck revealed
They are all worth a read.
The last one includes an informative video about German policy on hydrogen.
Green Hydrogen For Scotland
The title of this post, has been taken from this press release from ITM Power, which is entitled ‘Green Hydrogen For Scotland’ To Help Reach Net Zero Targets: First Project To Deliver A 10MW Electrolyser To Glasgow Facility.
This is the introductory paragraph.
A pioneering Strategic partnership has been established to create new green hydrogen production facilities with clusters of refuelling stations across Scotland, supporting the country’s efforts to achieve net zero by 2045. ‘Green Hydrogen for Scotland’ – a partnership of ScottishPower Renewables, BOC (a Linde company) and ITM Power – brings together industry-leading names in the renewables and clean fuel industries to offer an end-to-end market solution for reducing vehicle emissions through the provision of green hydrogen.
Other details include.
- The green hydrogen production facility located on the outskirts of Glasgow will be operated by BOC.
- ITM Power will deliver a 10 MW electrolyser.
- Electricity will come from , wind and solar produced by ScottishPower Renewables.
- The project aims to supply hydrogen to the commercial market within the next two years.
This ITM Power infographic outlines Green Hydrogen for Scotland.
Surely it should be called tartan hydrogen. Does anybody know a tartan containing the blue of Scotland, the white of Yorkshire and the black, red and gold of Germany?
Transition Your Ships To Zero-Emissions With Ballard’s New FCwave
The title of this post, is the same as that of this post on the Ballard blog.
This is the introductory paragraph.
Today, the maritime sector accounts for approximately 2.5% of global carbon emissions, equivalent to 940 megatonnes each year . But the industry is now moving into a new era of mobility, where sustainability and climate change issues are top of mind.
And this paragraph introduces Ballard’s solution.
At Ballard, we’re here to support ship operators and marine propulsion integrators in this transition. Today, we’ll introduce you to our new FCwave™ fuel cell module—the world’s first commercial fuel cell solution for marine vessels.
There is a link to a brochure.
The blog also has two videos and a picture of a Caledonian MacBrayne ferry, which is labelled Ballard Fuel Cell Powered HySeas Consortium Ferry, so is a hydrogen-powered ferry coming to an island near you or where you like to go?
This article on the Liverpool Echo is entitled Plans For A New Ferry To Cross The Mersey.
As the current two ferries, were in service when I was a student at Liverpool University in the 1960s, replacement of one of the most iconic, if not the most iconic ferries in the world with hydrogen power would be a smart move, by both Liverpool and Ballard.
Especially, as the Liverpool area is not short of hydrogen.
