Would A Dual-Fuel Boeing 747 Or Airbus A380 Save Carbon?
This press release from Airbus is entitled The ZEROe Demonstrator Has Arrived.
This is the introductory paragraph.
2022 marks a new and exciting phase for ZEROe – Airbus’ ambition to develop the world’s first zero-emission commercial aircraft by 2035. The multi-year demonstrator programme has officially been launched with the objective to test a variety of hydrogen technologies both on the ground and in the air.
The ZEROe demonstrator will be the first Airbus A 380 aircraft and it is shown in this Airbus visualisation.
Note.
- The four hydrogen tanks in the fuselage.
- The fifth engine mounted in a pod on the fuselage.
- There’s certainly lots of space inside the fuselage for more hydrogen tanks and test and monitoring equipment.
Take away the fifth engine and the test equipment and this aircraft becomes an A380 with two fuel systems; hydrogen and aviation fuel.
Consider.
- Suppose two engines were hydrogen-capable and two were normal engines running on aviation fuel or Sustainable Aviation Fuel (SAF).
- I don’t think it is impossible to build engines that could run on both hydrogen and Sustainable Aviation Fuel.
- All aircraft use fuel at a higher rate, during take-off and climbing.
- Do long non-stop flights use less fuel, than ones with stops?
- As altitude increases, air resistance decreases.
- Aircraft could fly slower to reduce the fuel needed, as they did in the oil crises in the last century.
- Generally, the most economical way to fly a route, is to climb to maximum altitude, fly level until descending into the destination.
- The aircraft would not carry cargo in the belly-hold.
- There could be a hydrogen-powered APU, as I wrote about in Airbus To Trial In-flight Auxiliary Power Entirely Generated By Hydrogen.
- This document from IATA says that in its liquid form, contains about 2.5 times more energy per kilogram than kerosene.
- The Boeing 747 first flew in 1969 and the Airbus A 380 in 2005, so these aircraft are well known.
I just wonder, if it is possible to work out a flight profile, that would enable these aircraft to fly very long non-stop routes?
- All four engines would be used for take-off.
- An appropriate power setting would be used for the cruise and the descent.
- There would be large numbers of 747s and A 380s in good condition to convert.
- The plane would land with little or no hydrogen left.
The hydrogen used would cut the carbon footprint of the flight.
Bradford Railway Station: Axed Plans For New Travel Hub Reconsidered
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Plans for a new railway station in Bradford will be reconsidered after the government previously scrapped them.
These paragraphs outline how the government has changed its mind.
Former Transport Secretary Grant Shapps cancelled the plan for Northern Powerhouse Rail (NPR), a brand new line serving the city, in November 2021.
The government has said an updated business case for the project was expected later this year.
West Yorkshire Mayor Tracy Brabin welcomed the news but criticised the “dither and delay”.
When the Integrated Rail Plan (IRP) was unveiled in 2021, it included cutting much of HS2’s eastern leg and scaling back NPR, including plans for a new station and line in Bradford.
The announcement that the government would now reconsider plans was made in the Department for Transport’s (DfT) response to the Transport Select Committee’s report on the IRP.
The committee had argued that the department had not properly tested alternative options to its proposals and had left out analysis of wider economic “levelling up” impacts of different options for NPR.
But there are no details yet.
Do We Know Anything?
The new station has been proposed to be built on the site of the current St. James Wholesale Market In Bradford.
This OpenRailwayMap shows the route of the railway between Leeds and Bradford Interchange stations, which runs via New Pudsey station.
Note.
- Leeds is to the East.
- Bradford Interchange station is in the North-West corner of the map.
- The yellow line across the map is the railway between Leeds and Bradford Interchange stations.
- St. James Wholesale Market is the rectangular building towards the top of the map in the middle.
- The dotted line going through the market is a disused goods line.
It is not obvious how the station will be connected to the rail network.
Silvertown Tunnel: Cracks In Mayoral Policies
The title of this post, is the same as that, as this article on the BBC.
This is the sub-heading.
It is an infrastructure project that is well-underway with the boring almost completed — but it has a very low profile.
These three paragraphs possibly explain why.
Every step of the Crossrail tunnelling, the media were invited along. Not so with this project.
This is Silvertown Tunnel. It is more than 1km long and will be London’s first road tunnel in over 30 years.
Perhaps one of the reasons it isn’t being pushed publicity-wise, is it is very controversial.
Reading the rest of the article it certainly is controversial in many people’s minds.
These are my thoughts.
Avoiding The Dartford Crossing
When I drove back to Suffolk from Gatwick, Kent or Sussex, in the last century, because of congestion at the Dartford Crossing, I would sometimes cut through London and use the Blackwall Tunnel, when I thought it would be quicker.
When the Silvertown Tunnel opens, this could be a viable alternative for vehicles.
My experience of modelling flows, tells me, that water finds its own level. With driving, Satellite Navigation will be able to tell drivers, which will be the fastest route.
It is my view, that the Silvertown Tunnel will become the biggest rat-run in London.
Except some of these rats will be super-rats in 45-tonne HGVs.
Cutting Pollution In London
If super-rat-running is going to happen, then this will raise pollution in Central London, with all those heavy trucks going through.
The only way to cut pollution would be to have differential pricing for vehicles in the tunnels.
Perhaps hydrogen and electric vehicles should be at a discount.
But then Sadiq Khan doesn’t have a hydrogen policy, except to ignore it and hope it goes away.
The Elizabeth Line Effect
Talking to Elizabeth Line staff at Whitechapel station, they feel that there is an increasing number of passengers, who do journeys in East London on an up-one-branch-down-t’other basis between places like Ilford and Woolwich.
I believe, that other cross-river railways and the Bank station improvements, will also take passengers out of their cars, which will free up the Silvertown Tunnel for more HGVs.
A City Airport Station On The Elizabeth Line
I wrote about this in Thoughts On London City Airport And The Elizabeth Line.
How many cars would this remove from the tunnels under the Thaames?
TfL Announces The Next Tube Stations To Be Prioritised For Step-Free Access To Meet The Mayor’s Bold Accessibility Targets
The title of this post is the same as that of this press release from Transport for London.
These are the first two paragraphs.
Transport for London (TfL) has outlined the ten London Underground stations it will be reviewing for potential step-free access, as it progresses plans to further improve public transport accessibility in London.
These ten stations, spread across London, have been identified using an approach focused on the benefits to customers, such as reducing journey times for those needing to use step-free access and reflecting issues that impact the delivery of step-free access such as the feasibility of new lifts, sufficient space for work to be carried out and the depth of each Tube station.
The ten stations listed are.
- Alperton
- Arnos Grove
- Burnt Oak – Some work has been started, but paused because of the pandemic
- Eastcote
- Finchley Road
- Northolt – Some work has been started, but paused because of the pandemic
- North Acton
- Rayners Lane
- West Hampstead
- White City
The linked posts will show the latest status at the stations.
Other stations are named in the press release, where work will be done, if funds are available.
- Boston Manor
- Brondesbury
- Colindale
- East Putney
- Hackney Downs
- Hatton Cross
- Leyton
- North Ealing
- Park Royal
- Peckham Rye
- Queen’s Park
- Rickmansworth
- Ruislip
- Snaresbrook
- Surrey Quays
in addition, TfL will be looking at the Northern Line between Elephant and Castle and Morden, where there is a gap in step-free access.
These are a few thoughts.
The London Mayor Election In 2024
How many of these stations are in areas, where Sadiq Khan is short of votes for the 2024 election?
Arnos Grove Station
Work has already started at Arnos Grove station, as I showed in Are Arnos Grove And Northolt Tube Stations Going Step Free?.
The BBC Jumped The Gun
The press release now explains the BBC story from Mpnday, that I wrote about in Are Arnos Grove And Northolt Tube Stations Going Step Free?.
Are Arnos Grove And Northolt Tube Stations Going Step Free?
BBC London local news announced this morning some Underground stations would be made step-free.
- It could have been two or ten stations, that would be made step-free.
- Arnos Grove and Northolt were definitely mentioned.
- A timescale of eighteen months was given.
The news story seems to have vanished without trace.
Arnos Grove Station
This Google Map shows Arnos Grove station.
Note.
- The cylindrical shape of Arnos Grove station.
- The bridge over the tracks, which gives access to the trains to the East of the cylinder.
- Car parks to the East and West of the station.
- In Go-Ahead For West London 460-Home Build To Rent Scheme, I described how houses were to be built in the two car parks.
- According to this article on Ian Visits, which is entitled Plans To Build Flats On Arnos Grove Tube Station Car Park, there will be 162 flats in four blocks.
These pictures show Arnos Grove station.
Note.
- Work on the flats on either side seems to have started.
- There are lots of period features.
- There will be a lot of work needed on the rather steep stairs.
- There will be a need for at least three lifts.
This page on Connected Living London, has a plan of the development.
- Gardens are shown each side of the iconic station.
- The gardens can be accessed from the pavement in front of the station.
- Southbound buses draw up in front of the station.
- A zebra crossing gives access to the Northbound buses on the other side of the road.
I suspect that there will be step-free access to the station bridge over the tracks from both gardens.
Northolt Station
This Google Map shows Northolt station.
Note.
- The station entrance in the South-East corner of the map on Mandeville Road.
- The long island platform stretching North-West from the station building.
- An eight-car 1992 Stock train is in the Southern platform going West.
- The land on the Northern side of the railway appears to be low-grade woodland, which is quite similar to that at Arnos Grove station.
This map from cartometro.com shows the lines through Northolt station.
Note.
- The Central Line is shown in red.
- The Central Line is laid out so that there are two ways of turning a train back to London.
- The single-track Acton-Northolt line is shown in black.
- The former second track if the Acton-Northolt line is shown dotted, as are the two former platforms.
These pictures show Northolt station.
Note.
- The station is showing signs of a sympathetic refurbishment.
- The steps down to the platform is a double set of steps separated by a handrail.
- There is a stylish glass shelter.
- There doesn’t seem much space for a lift to the station entrance.
It should also be noted that for eleven in the morning, the station seemed busy.
These are Underground passenger figures for 2021 in million for stations between Hanger Lane and West Ruislip.
- Hanger Lane – 1.47
- Perivale – 1.08
- Greenford – 2.05
- Northolt – 2.47
- South Ruislip – 0.89
- Ruislip Gardens – 0.48
- West Ruislip – 0.71
Note.
- Greenford, South Ruislip and West Ruislip have some extra National Rail passengers.
- Greenford is the only station between Hanger Lane and West Ruislip, with full step-free access.
- Greenford station uses an inclined lift and I wrote about it in The Inclined Lift In An Improved Greenford Station.
As Northolt is the busiest station without step-free access, this is probably sufficient reason for step-free access to be installed.
Could Step-Free Access At Northolt Be Linked To Property Development?
This Google Map shows a close-up of the station building and Mandeville Road.
Note.
- The station building is marked by the London Transport roundel.
- To the North of the station, is Northolt Leisure Centre, which was opened in 2010.
- Mandeville Road runs across the map to the East of the station and the Leisure Centre.
- In the South-East corner of the map, thee looks what could be a High Speed Two site, marked out with red and white barriers.
- Between the station and the Leisure Centre, there appears to be a site used for parking trucks.
Could it be possible to develop step-free access from the site to the North of the station?
This second set of pictures show that site.
Note.
- The site is rather a dump.
- There is even a subway.
This third set of pictures, show the land on the other side of the Acton-Northolt line from the platform at Northolt station.
There are certainly possibilities! Especially if, housing were to be developed alongside the Northern side of the railway.
I suspect, that there could be a bridge across the railway, at this position in the station.
Certainly something would be possible.
Conclusion
Property development at both Arnos Grove and Northolt station would probably need step-free access at both stations.
If the BBC report was right, then to build the step-free access as the first part of the projects, is probably a good idea, as passengers get some early benefits.
I suspect though, that we’ll get a press release that says what is actually happening in a few days.
A Spelling Mistake From Hydrogen Fuel News
This clipping from Hydrogen Fuel News contains one of the best spelling mistakes I’ve seen in a long time.
It wasn’t auto-suggestion, as the only lady in the article, is very demurely dressed.
Centrica To Build Largest Battery Storage Project To Date
The title of this post, is the same as that of this news item from Centrica.
These three paragraphs outline the news.
Centrica Business Solutions has secured the development rights to a 65MW two-hour battery storage plant in Perthshire, Scotland, its largest battery storage acquisition to date.
The site in Abernethy is located near a connection for North Sea offshore wind farms and will help manage grid capacity by charging when demand for power is low, and discharging when demand is at its highest.
Once connected to the grid in 2028, the 65MW two-hour battery will be able to store enough electricity to power 130,000 homes for an hour – the equivalent to a town the size of Aberdeen. The discharge could happen up to four times a day.
This map shows the site of the substation at Abernethy.
It seems a site with enough space for a 65 MW/130 MWh battery.
But is that a railway running past the site in the South-East corner of the map?
Yes! It is the single-track unelectrified railway that is used by trains to go between Edinburgh and Perth.
- There are stations at both ends of the single-track section at Ladybank and Perth.
- Abernethy substation looks like it is about halfway between the two end stations.
This page on Scotland’s Railway is entitled Fife Electrification and lists these four phases.
- Haymarket and Dalmeny
- Kinghorn and Thornton North
- Thornton and Lochgelly
- Thorton and Ladybank
The page also says that the electrification will support BEMUs (Battery Electric Multiple Units)
I feel that the electrification to Ladybank and Centrica’s battery could be linked.
- If the electrification was extended a few miles to Abernethy substation, this would surely be a reliable way to power the electrification.
- It would also be ideally placed, if Perth and Ladybank were to be electrified.
- The new battery would surely smooth out any deviations in the power supply.
I certainly don’t expect that Centrica will object to a new customer.
Electrification Between Edinburgh And Ladybank
Consider.
- Edinburgh and Ladybank is 39 miles and takes a couple of minutes over an hour.
- Once, the four phases of the electrification are complete, only the 13.6 miles between Dalmeny and Kinghorn, will be without electrification.
- I doubt that Dalmeny and Kinghorn will ever be electrified, as it includes the Forth Rail Bridge.
- Dalmeny and Kinghorn is 13.6 miles and takes around twenty-four minutes.
It looks like the BEMUs will be under wires for 25.4 miles and nearly forty minutes, which will be more than enough to charge the trains.
Edinburgh And Aberdeen
In Thoughts On Batteries On A Hitachi Intercity Tri-Mode Battery Train, I said this about services between Edinburgh and Aberdeen.
Consider.
-
- The gap in the electrification is 130 miles between Edinburgh Haymarket and Aberdeen.
- There could be an intermediate charging station at Dundee.
- Charging would be needed at Aberdeen.
I think Hitachi could design a train for this route.
The 25.4 miles of new Fife electrification between Haymarket and Ladybank will reduce gap in the electrification to 105 miles and ensure trains leaving Ladybank for Aberdeen had a full battery.
Discover How Greater Brighton Is Championing The Transition To Hydrogen
The title of this post, is the same as that of this news item from Brighton & Hove Council.
This is the introduction to the news item.
Local experts will present the strengths and opportunities for developing the hydrogen economy in the Sussex area at an online launch on 11 July.
Register for the online launch of the Hydrogen Strategy
Developed by local company Ricardo, on behalf of Hydrogen Sussex, the Greater Brighton Hydrogen Strategy shows that with the right focus, collaboration and action, the region has real potential to stand out within the UK hydrogen landscape and gain economic and environmental benefits.
Brighton & Hove Council seem to be taking a sensible approach, but then they do have one of the world’s most respected hydrogen companies; Ricardo, a few miles to the West.
This section outlines, how Brighton is embracing hydrogen.
Hydrogen is a fast-growing sector with the potential to enable decarbonisation, support national energy security, create green growth and improve air quality.
The Greater Brighton and wider Sussex area has already broken ground in the Hydrogen industry, with advanced engineering, education and research being very well represented. Local initiatives include:
-
- Hydrogen buses: Metrobus has just launched 15 hydrogen buses to serve the Crawley and Gatwick area, with a further 34 hydrogen buses joining their fleet over the next 18 months.
- Shoreham Port: The port is working with partners H2Green to create a Green Energy Hub, producing green hydrogen in a multi-megawatt electrolysis plant – initially for Shoreham Port, and then supplying green hydrogen across the region.
- Maritime sector: Sussex’s engineering companies are at the forefront of hydrogen decarbonisation in the maritime sector. Bramble Energy, Cox Marine, Ceres Power and Ricardo are just some of the local companies which have received Government funding to tackle marine decarbonisation.
- Sussex and Brighton universities: The two universities in the area have PHD studies on innovations in the sector, with Brighton University partnering with companies to win government research funding.
- Worthing Crematorium: Could become the first in the world to trial a switch to 100% hydrogen. If testing is successful with cremator manufacturer DFW Europe, hydrogen technology will be brought over to Worthing Crematorium as early as spring 2024.
The region is already home to several hydrogen technology companies and has a strong capacity for innovation which could be developed to expand its engineering excellence.
That list looks fairly comprehensive.
Conclusion
Other towns, cities and regions in the UK, should look at what Brighton is doing, with respect to hydrogen.
Eltham Station – 6th July 2023
I’d never used Eltham station until yesterday. But as I’d documented half of bus route 132 for Exploring London Bus Route 132, it seemed a good place to start following the second part.
I took these pictures as I passed through.
The station is an unusual design, which is summed up, in this paragraph from the stations, Wikipedia entry.
Both stations were closed and replaced by the current station which was opened by British Rail on 17 March 1985 when a new section of the A2, the Rochester Way Relief Road, was opened. A bus station that was built on a raft above the A2 was opened at the same time.
This Google Map shows the layout of the station.
Note.
- The station is step-free using ramps.
- There are no lifts, but I suspect they could be easily added.
- On my visit yesterday, I hadn’t realised that there was a dual-carriageway road underneath the station.
- It is a comprehensive interchange between trains and buses.
For the 1980s, it is an excellent example of a station built to modern principles.
The underlying principle of this station could be used to create transport interchanges where railways, major rods and busy bus corridors intersect.
