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.
Italian Firm To Build Green Hydrogen Platform For CrossWind’s Hollandse Kust Noord
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
CrossWind has awarded Rosetti Marino an Engineering, Procurement, Construction, and Installation and Commissioning (EPCIC) contract for an offshore green hydrogen production and storage plant, located within CrossWind’s Hollandse Kust Noord offshore wind farm in the Netherlands.
These paragraphs describe the platform.
Rosetti Marino said that the pilot plant, called the Baseload Power Hub and fully integrated into an offshore wind farm, is a world first.
The plant on a MegaWatt scale will convert excess wind energy to green hydrogen through an electrolyser and store it as green hydrogen that can be converted to electricity when needed via a fuel cell.
It will also include battery storage for shorter-term power storage.
It looks like they’ve got all angles covered.
I suspect that we’ll see more platforms like this, as they should make the output of a wind farm much more controllable.
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.
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.
Exploring London Bus Route 132
London Bus Route 132, is run by battery-electric buses and it the first in London to use opportunity charging.
These pictures show the route from North Greenwich to Bexleyheath Shopping Centre.
Note.
- These pictures were shot in two sections on the 3rd and the 6th of July 2023.
- The break was at Eltham station.
- Some sections of the route had a lot of cars.
- Some side roads were full of parked cars.
- There were large numbers of cars parked in front of houses.
There are my thoughts.
More will appear here over the next couple of days.
The Buses
The buses used on the route are Alexander Dennis Enviro400EV, which are built on a BYD Auto chassis.
They have a range of 160 miles.
The Route
The route has several inclines both ways and I estimate it is just under ten miles.
At North Woolwich, the bus didn’t appear to have a charge, but I can’t be sure.
But it disappear at Bexleyheath Shopping Centre and I was certain it went for a charge.
So is the operational philosophy to fill, the bus up overnight and then top the battery up every time, that it needs it at Bexleyheath.
A Comparison With A Similar Route In Birmingham That Has Hydrogen-Powered Buses
As the bus ran between North Woolwich and Bexleyheath Shopping Centre, I was comparing it, with the trip, I made across Birmingham, in hydrogen-powered buses, that I wrote about in Riding Birmingham’s New Hydrogen-Powered Buses.
Both were quality buses, but I felt the hydrogen bus had more power.
Opportunity Charging At Bexleyheath
If, buses need to be charged at the Bexleyheath Shopping Centre end of the route, where will they go?
This Google Map shows Bexleyheath Bus Garage in relation to the Shopping Centre.
Note.
- Bexleyheath Bus Garage is in the North-East corner of the map.
- It looks like it shares a site with Bexley Fire Station and Barnehurst Ambulance station.
- So the garage is well located for any future lithium-ion battery fires.
- In the middle of the map at the bottom, is Bexleyheath Clock Tower, in the middle of the town centre.
- I estimate it’s less than two kilometres between Bexleyheath Bus Garage and the Shopping Centre.
This Google Map shows a close-up of the Western side of the Bexleyheath Bus Garage.
Note.
- The two buses parked by the side of the garage.
- Behind them a white arm reaches over towards the road.
- This is the charger and buses connect using a pantograph on the roof.
It could be an All-In-One Fast Charging Station AIO from Furrer+Frey.
The Electrical Connection At Bexleyheath Bus Garage
Consider.
- The bus garage shares a site with a fire station and an ambulance station, which surely must need a reliable power source.
- This is London’s first application of opportunity charging.
- There are improvements constantly happening to London’s struggling power network.
- It is a large site and I suspect there is space for a battery to boost power.
I would assume that Transport for London wouldn’t have chosen a bus garage with a dodgy power supply.
Could The Charger Be Solar-Powered?
This Google Map shows the roof of Bexleyheath Bus Garage.
Note.
- It appears to be a square with a length of about six buses.
- It looks rather dirty.
I suspect that the roof could be replaced with a modern solar roof.
Hydrogen Or Electric
This article on RouteOne is entitled Enviro400FCEV Hydrogen Bus Fleet For Liverpool Debuts.
This paragraph describes the performance.
Alexander Dennis has chosen the heavy-duty variant of VEDS. It is designed to deliver up to 410kW of power, but the vehicle OEM says that in the Enviro400FCEV, output is limited to 350kW. Such an approach will maximise fuel economy while still enabling a high road speed and good hill climbing ability. Expected range is up to 300 miles.
So the range on hydrogen is nearly doubled.
Wrightbus’s outwardly similar electric and hydrogen buses have ranges of 200 and 280 miles, but filling times of 2.5 hours and 8 minutes.
The problem with hydrogen in London, is that the Mayor and Transport for London, don’t appear to have a hydrogen policy.
But I think, that hydrogen will win out in cities and areas, where hydrogen can be supplied.
I also believe that hydrogen has other advantages.
- There is likely to be significant progress in improving hydrogen-powered heavy vehicles.
- Hydrogen internal combustion engines are coming and could promise more affordable hydrogen buses.
- Better and more affordable methods to create green hydrogen are being developed.
- Some existing diesel buses will be able to be converted to buses powered by hydrogen internal combustion engines.
- Lithium-ion batteries have a high environmental footprint.
Hydrogen is also likely to be the fuel of choice for heavy trucks.
Thoughts On The Future Of Orkney
This article on the BBC is entitled Orkney Votes To Explore ‘Alternative Governance‘
This is the sub-heading.
Orkney councillors have voted to investigate alternative methods of governance amid deep frustrations over funding and opportunities.
These paragraphs outline the story.
Council leader James Stockan said the islands had been “held down” and accused the Scottish and UK governments of discrimination.
His motion led to media speculation that Orkney could leave the UK or become a self-governing territory of Norway.
It was supported by 15 votes to six.
It means council officers have been asked to publish a report to Orkney’s chief executive on options of governance.
This includes looking at the “Nordic connections” of the archipelago and crown dependencies such as Jersey and Guernsey.
A further change which would see the revival of a consultative group on constitutional reform for the islands was accepted without the need for a vote.
My Thoughts On The Economic Future Of The Islands
The economic future of Orkney looks good.
Tourism and the traditional industries are on the up, but the islands could play a large part in renewable energy.
The West of Orkney offshore wind farm, which will be a 2 GW wind farm with fixed foundations, is being developed and a large hydrogen production hub at Flotta is being proposed, along with the development of a large quay in Scapa Flow for the assembly of floating wind farms.
The West of Orkney wind farm could be the first of several.
If the future wind farms are further from shore, they will most likely be based on floating technology, with the turbines and their floats assembled in Scapa Flow, from components shipped in from mainland UK and Europe.
Political Future
With a good financial future assured, I believe that Orkney will be able to choose where its political future lies. It could be a Crown Dependency or join Norway.
Whichever way it goes, it could be an island that effectively prints money, by turning electricity into hydrogen and shipping it to countries like Germany, The Netherlands, Poland and Sweden!
From a UK point of view, a Crown Dependency could be a favourable move.
Would Shetland follow the same route?
Offshore Hydrogen Production And Storage
Orkney is not a large archipelago and is just under a thousand square kilometres in area.
It strikes me, that rather than using up scarce land to host the large electrolysers and hydrogen storage, perhaps it would be better, if hydrogen production and storage was performed offshore.
Aker Northern Horizons
In Is This The World’s Most Ambitious Green Energy Solution?, I talk about Northern Horizons, which is an ambitious project for a 10 GW floating wind farm, which would be built a hundred kilometres to the North-East of Shetland, that would be used to produce hydrogen on Shetland.
Other companies will propose similar projects to the West and East of the Northern islands.
This map shows the sea, that could be carpeted with armadas of floating wind farms.
Consider.
- There are thousands of square miles of sea available.
- As the crow flies, the distance between Bergen Airport and Sumburgh Airport in Shetland is 226 miles.
- A hundred mile square is 10,000 square miles or 2590 square kilometres.
- In ScotWind Offshore Wind Leasing Delivers Major Boost To Scotland’s Net Zero Aspirations, I calculated that the floating wind farms of the Scotwind leasing round had an energy density of 3.5 MW per km².
- It would appear that a hundred mile square could generate, as much as nine GW of green electricity.
How many hundred mile squares can be fitted in around the UK’s Northern islands?
Lloyd’s Register Issues World’s First Rules For Hydrogen Fuel
The title of this post, is the same as that of this article on Hydrogen Central.
These are the first two paragraphs.
Lloyd’s Register issues world’s first rules for hydrogen fuel.
Liam Blackmore, Lead Specialist at Lloyd’s Register, is a busy man. He has led the technical policy writing of many of the class society’s decarbonisation rules. Horizons spoke to him in late April 2023, just a few weeks after LR had published the world’s first maritime rules covering hydrogen as a fuel.
This would appear to be a very sensible move by Lloyds Register, which sets down the rules for using hydrogen fuel on ships.
But surely, if you follow these rules, then you will able to get insurance for your ship.
World’s First Offshore Hydrogen Production Project Yields First Kilograms Of Green Hydrogen
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The offshore hydrogen production platform that Lhyfe is testing in France, named Sealhyfe, began producing its first kilograms of hydrogen on 20 June after it was towed last month to the SEM-REV offshore test site which is connected to BW Ideol’s floating wind turbine Floatgen.
These two paragraphs introduce the article.
Sealhyfe is capable of producing up to 400 kilograms of hydrogen per day.
With the start-of-production milestone now reached, the platform has entered the second phase of testing, which focuses on producing hydrogen in offshore conditions, after eight months of being tested at a quay in the Port of Saint-Nazaire, starting in September 2022.
The setup features a 1 MW electrolyser.
This may only be a small start, but I do feel that we’ll see more offshore hydrogen production.
According to Lhyfe And Centrica To Develop Offshore Renewable Green Hydrogen In The UK, Centrica and Lhyfe seem to be co-operating.
It should be noted that this year, I’ve written seven posts involving Offshore Hydrogen Production.
My Second Ride In A Wrightbus Single-Decker Hydrogen Bus
Or it might have been the third or fourth, but it was the first outside of London in a single-decker Wrightbus hydrogen bus. The earlier rides were in the RV1 route, which I wrote about in London’s Hydrogen Buses.
I took these pictures.
Note.
The trip was in Crawley and Go-Ahead are building a network of hydrogen buses to link the town and Gatwick Airport.
- It was a high quality bus.
- It was busy.
- It was the first bus, I’d seen in the UK, with a detailed route.
Someone had been thinking about how to design a bus route.
SSE Becomes First Utility To Trial First Hydrogen Fuel Cell EV Van
hydrThe title of this post, is the same as that of this article on Hydrogen Central.
This is the first two paragraphs.
The low-carbon energy infrastructure company will be the first utility to trial the hydrogen-powered vehicle – and the first to put it to the test in real-life fleet operations by deploying the vehicle with SSE engineers.
The project will enable First Hydrogen’s team to gather data on fuel consumption, usage, and efficiency. The trials are being used to inform development of First Hydrogen’s Generation II series, currently in development, and will help enhance Total Cost of Ownership (TCO) data.
The deployment will take place in Aberdeen, as the city has some of the UK’s best hydrogen infrastructure.
The Mayor of London please note how being a hydrogen denier causes London to have more pollution.
