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.
