The First Hydrogen Trains Have Been Ordered
This article on Global Rail News is entitled Alstom Confirms Orders For Its Hydrogen-Powered Coradia iLint.
There is also this Press Release on the Alstom web site, which gives a lot more details.
Given that this is a real order worth millions of euros, I think we can assume that another practical motive power source for trains has arrived.
One interesting point is that the deal involves the Linde Group, who are the world’s largest industrial gas company.
World’s First Hydrogen-Powered Tram Runs In China
The title of this post is the same as this article on Global Rail News.
This is the first two paragraphs.
Rolling stock manufacturer CRRC has announced that the world’s first hydrogen-powered tram has been put into passenger operation in China.
The three-carriage hybrid electric tram enter service in the city of Tangshan, Hebei, on October 26.
It seems to have the following characteristics.
- Three cars
- 66 seats
- 70 kph.
- 40 km range.
It all sounds very tram-like.
It does seem there’s a lot of train and tram manufacturers thinking about hydrogen power.
Could Bombardier Build A Hydrogen-Powered Aventra?
In Is A Bi-Mode Aventra A Silly Idea?, I looked at putting a diesel power-pack in a Class 720 train, which are Aventras, that have been ordered by Greater Anglia. I said this.
Where Would You Put The Power Pack On An Aventra?
Although space has been left in one of the pair of power cars for energy storage, as was stated in the Global Rail News article, I will assume it is probably not large enough for both energy storage and a power pack.
So perhaps one solution would be to fit a well-designed power pack in the third of the middle cars, which would then be connected to the power bus to drive the train and charge the battery.
This is all rather similar to the Porterbrook-inspired and Derby-designed Class 769 train, where redundant Class 319 trains are being converted to bi-modes.
I also suggested that a hydrogen power-pack could be used.
After writing Is Hydrogen A Viable Fuel For Rail Applications?, I feel that a similar hydrogen power pack from Ballard could be used.
The Wind Of Change Blowing All Over The UK
This has nothibg to do with Brexit or even politics, but the UK and in addition our friends in Denmark, Germany, Ireland and The Netherlands seem to be investing to reap the wind.
To many of my generation, Hornsea is a town on the Yorkshire coast famous for dull ethnic pottery. But now it will the name of the Hornsea Wind Farm, which will have a generating capacity of up to 4 GigaWatt or 4,000,000 KiloWatt. It will be sited around 40 kilomwtres from the nearest land.
To put the size into context, Hinckley Point C, if it is ever built will have a power output of 3.2 GigaWatt.
You may day that wind is unreliable, but then Hornsea will be just one of several large offshore wind farms in the UK.
- Dogger Bank(4.8 GW),
- Greater Gabbard(504 MW)
- Gwynt Y Mor(576 MW)
- London Array(630 MW)
- Race Bank(530MW
- Thanet(300 MW)
- Yriton Knoll(600-900 MW)
- Walney Extension (659 MW).
The electricity produced can be used, stored or exported.
Storage will always be difficult, but then there are energy consumptive industries like aluminium smelting, creating steel from scrap or the electrolysis of water to produce hydrogen, oxygen and ither gases, that could probably be based around an interruptible supply backed-up by a biomass or natural gas power station.
Hydrogen As A Fuel
Hydrogen could be the fuel of the cities for buses, taxis and delivery vehicles. Suppose they were hybrid, but instead of a small diesel engine to xharge the battery, a small hydrogen engine or fuel cell were to be used.
Remember that the only product of burning hydrogen is water and it wouldn’t produce any pollution.
Each bus garage or hydrogen station could generate its own hydrogen, probably venting the oxygen.
Enriched Natural Gas
We can’t generate too much hydrogen and if because of high winds, we have hydrogen to spare it can be mixed with natural gas, ehich contains a proportion of hydrogen anyway.
Could This Be The Key To Hydrogen Power?
Jerry Woodall has form as a scientist and inventor as he developed the first commercially-viable red LEDs that we see in car brake lights and traffic signals.
Last night I was searching for something else and came across this video on YouTube. This is the description to go with the video.
The actual process: gallium and aluminum combining, add water. stir – bubbles of hydrogen with only white aluminum oxide. as demonstrated by John Woodall – Jerry M. Woodall, National Medal of Technology Laureate, Distinguished Professor of School of Electrical and Computer Engineering, Purdue University, West Lafayette.
To put it simply, you add water to aluminium doped with gallium and the aluminium combines with the oxygen in the water and the hydrogen is released. The hydrogen can then be used to power a small engine.
There’s more description here on phys.org.
It’s early days yet, but could this simple process be the key to hydrogen power?
I always remember in the Electrical Engineering Department at Liverpool University in the 1960s, we were shown one of the first lasers. In some ways then, it was just a scientific curiosity and people were speculating about how they could be used. Now everybody has at least one, if they have a CD player. Many people reading this will be navigating the Internet using a laser mouse, as in fact I am with a Logitech M525.
It may not use Jerry Woodall’s invention, but at some time in the future, you’ll just put water in the fuel tank of your car and just drive away, emitting nothing more than water vapour.
There are many problems to solve, but the internal combustion engine will be here hundreds of years from now.
