Solving The Problem With Electric Bus Design
The title of this post, is the same as that of this article on Electric & Hybrid Vehicle Technology International.
The article opens with this paragraph.
A number of European cities have committed to securing only zero-emission buses by 2025. However, to achieve this objective, manufacturers must make bold design choices, radically changing bus componentry, systems, and bodywork. Here, it looks at the debate for greater electric bus design standardization.
Standardisation is one thing, but the article doesn’t talk about the major problem with electric bus design – For many countries like the UK, Hong Kong, Singapore and Germany, where there are lots of double-decker or articulated high-capacity buses, battery electric buses are just not big enough.
Battery-electric buses are also generally not big enough to compete with the latest designs of tram and metro systems.
These pictures show the Chinese double-deck electric double-deck buses, that ran in London.
Half of the downstairs was take up by batteries.
Where are they now?
The Belgian firm; Van Hool have a product called Exquicity. This video shows them working in Pau in France.
But these buses are powered by hydrogen.
Similar buses running in Belfast are diesel-electric.
In both the Pau and Belfast applications, I wonderwhy they didn’t use trolley-bus versions of the WxquiCity or conventional trams.
Conclusion
Until we get more efficient battery storage, electric buses will have difficulty competing economically in the high-capacity bus sector.
Green Bus Maker Reveals Plan For Scottish Hydrogen Fuel Production Facility
\the title of this post, is the same as that of this article on the Herald.
Thwaw are the introductory paragraphs.
Jo Bamford, chief of Ryze Hydrogen, has revealed plans to create a hydrogen production facility in Scotland.
He said the production unit will be sited outside Glasgow and it is expected to be operational by November next year when the rescheduled COP26 climate event is due to take place in the city.
Mr Bamford earlier said Glasgow could run 300 hydrogen-powered buses, while Aberdeen is set put a fleet of hydrogen powered double deckers on the road.
You can’t fault Jo Bamford’s ambitions.
World’s First Hydrogen-Powered Double Decker Buses To Be Launched In Scotland
The title of this post, is the same as that of this article on The Herald.
This introduction says a bit more.
A fleet of hydrogen-powered double decker buses that is claimed to be the world’s first is due to be launched in Scotland later this year in what is seen as a major step forward in the use of hydrogen as a fuel.
First Aberdeen will be running fifteen hydrogen-fuelled buses.
Hamburger Hochbahn Launches Tender For 50 Hydrogen Fuel Cell Buses
The title of this post, is the same as that of this article on H2 View.
The title says it all!
But it does show how hydrogen buses are proliferating around the world.
This makes the third hydrogen or energy project from the German city, that I have detailed.
Diesel Buses To Be Phased Out Within 15 Years To Cut Greenhouse Gas Emissions

Hallelujah!
Should be heavy trucks, next!
Ryze Hydrogen-Suttons Tankers Partnership To Supply Hydrogen To Transport for London
The title of this post, is the same as that of this article on H2 View.
From reading the article, it looks like London’s new hydrogen buses will be on the road by the end of the year.
Sadly, in some ways, the hydrogen will have to be driven from Runcorn, as the Herne Bay electrolyser won’t be completed for a couple of years.
I would assume, that the hydrogen is coming from the plant where I worked around 1970, or more likely its successor.
15 More Fuel Cell Electric Buses For UK Roads
The title of this post, is the same as that of this article on H2 View.
This is the introductory paragraph.
A further 15 fuel cell electric buses (FCEBs) are planned for the UK this year, as the country works towards its goal of deploying 4,000 zero emission buses over the next five years.
These futher points are made.
The fuel cells are 85KW heavy-duty FCveloCity®-HD fuel cell modules from Ballard Power Systems.
This will take Wrightbus’s order book for hydrogen-powered buses to fifty. all of which will be delivered this year.
Twenty buses are for London and fifteen are for Aberdeen.
I have some thoughts on the 85KW heavy-duty FCveloCity®-HD Fuel Cell Module.
This pdf file on the Ballard web site is the data sheet and this is selected data.
- The net power is 85 kW
- The fuel cell weighs 256 Kg.
- It needs a coolant sub-system that weighs 44 Kg.
- It needs an air sub-system that weighs 61 Kg.
- It is a true zero-emission product.
It is worth looking at the power train of a New Routemaster bus, which although very different will probably give clues as to the weight that can be carried and the power and battery size needed for a full-size bus.
- The Cummins ISBe diesel engine develops 138 kW and weighs 499 Kg.
- The engine is mounted half-up the back stairs.
- The Microvast Lithium Titanate battery has a capacity of 18 kWh.
- The battery is placed under the front stairs.
- The braking on the New Routemaster bus is regenerative.
These are some of my observations.
- If you sit at the back of a New Routemaster bus, you can hear the engine, when it is running. On most routes in Central London, it certainly isn’t running all the time.
- The battery doesn’t seem very large at 18 kWh.
- The fuel cell with its sub-systems would appear to be lighter than the diesel engine, but of less power.
- The fuel-cell won’t need the generator of the diesel bus.
I very much feel getting all the components into a standard double-decker bus will be a tight squeeze, but none of the individual components are that large or heavy.
Conclusion
I can’t wait to have my first ride in a hydrogen-powered double-decker bus.
Ryze Hydrogen Wants To Make The North East Of Scotland A World Leader In Hydrogen
The title of this post, is the same as that of this article on H2 View.
This is the introductory paragraph.
Ryze Hydrogen has pledged to work with the Scottish Government and local authorities to make the North East of Scotland a world leader in hydrogen.
I think this is both a laudable and a very sensible aim.
- Large offshore wind farms are being built both around Aberdeen and the Far North of Scotland.
- Production of hydrogen is a sensible way to use spare renewable electricity.
- That area of Scotland is not short of wind.
- Aberdeen will be taking delivery of hydrogen buses later this year.
- With their experience of the oil industry, there would not be a shortage of people with the necessary expertise.
The article also details Jo Bamford’s plans for hydrogen buses.
‘Chernobyl’ Fears Dismissed As Herne Bay Hydrogen Plant Bid Approved
The title of this post, is the same as that of this article on Kent Online.
it would appear that Kent Online got their prediction right. that I wrote about in Hydrogen Power Plant Bid In Herne Bay Set For Green Light From Canterbury City Council.
Hydrogen Power Plant Bid In Herne Bay Set For Green Light From Canterbury City Council
The title of this post, is the same as that of this article on Kent Online.
These are the introductory paragraphs.
Controversial plans to build a hydrogen fuel plant on a rundown plot of land look set to be given the green light – despite more than 160 objections from concerned residents.
Canterbury City Council was inundated with letters from locals – with one even worried about a Fukushima-style disaster – after a bid to construct the plant in Westbrook Lane, Herne Bay, was revealed in January.
The article said, that the project would create twenty jobs.
This Google Map shows the proposed site for the electrolyser.
Note.
- The Railway running East-West at the top of the map.
- The A2990 Thanet Way running East-West at the bottom of the map.
From a visualisation on the Kent Online article, it appears that the electrolyser will be built to the West of the Recycling Centre.
I suspect that given the closeness of the railway, it might even be possible to despatch hydrogen to users by specially-designed trains.
The electrolyser will need large quantities of electricity and I can’t see any wires around the site.
This Google Map shows the wider area around the site.
Note.
- The Recycling Centre indicated my a blue arrow, just to the right of top-centre of the map.
- The A2990 running East-West across the top of the map.
- The 18 MW Molehill Solar Farm between the old and new Thanet Ways, in the middle of the map.
- The 51.9 MW Owls Hatch Solar Farm, in the South East corner of the map.
- For full production, the electrolyser needs 23 MW!
These two solar farms, mean, that there must be a high-quality electricity connection in the area.
With all the offshore wind in Kent and these solar farms on the doorstep, the Herne Bay electrolyser, will not have much difficulty obtaining genuine renewable electricity.
Conclusion
As someone, who once worked, in a hydrogen factory, I would be happy to live near to the site.
Are Ryze Hydrogen planning to put a filling station for hydrogen vehicles on the A2990?
