Vivarail Targets Overseas Markets
The title of this post, is the same as that of this article on Rail Magazine.
This is an extract from the article.
Shooter told RAIL: “We are at the moment putting together a bid for an operator – not in this country – where the routes would be up to 500 miles long, to be provided totally with battery trains using this device.
“This bid we are putting together contemplates trains that are running for several hours – 60 to 70 miles between charging stations, but possibly going twice that far in emergency if the charging station should go down.”
By this device I suspect they mean their Fast Charge device, which is described in this press release from Vivarail.
This extract describes how it works.
The concept is simple – at the terminus 4 short sections of 3rd and 4th rail are installed and connected to the electronic control unit and the battery bank. Whilst the train is in service the battery bank trickle charges itself from the national grid – the benefit of this is that there is a continuous low-level draw such as an EMU would use rather than a one-off huge demand for power.
The train pulls into the station as normal and the shoegear connects with the sections of charging rail. The driver need do nothing other than stop in the correct place as per normal and the rail is not live until the train is in place.
That’s it!
That sounds simple to me.
Where Would This Possible Order Be From?
I have ridden in a Vivarail battery train, as I wrote in Battery Class 230 Train Demonstration At Bo’ness And Kinneil Railway.
I have also ridden the diesel variant, as I wrote in A First Ride In A Revenue-Earning Class 230 Train.
I very much feel, I can list a few of the good qualities of the trains.
Big Windows
The big windows give a good view, so I wonder if the trains would work well on a railway noted for its scenery.
Quietness
I have ridden in two battery trains.
The other was Bombardier’s Class 379 BEMU, that I wrote about in Is The Battery Electric Multiple Unit (BEMU) A Big Innovation In Train Design?.
Both were extremely quiet.
No Infrastructure Required
Except for the charging stations, no infrastructure is required.
Sturdy Engineering
Although the trains were only originally built for the London Underground, they are sturdily-built trains, as they used to share tracks with full-size trains.
I suspect, they are certified to share tracks with freight trains, as they do on the Marston Vale Line.
A Range Of Interiors And Customer Facilities
Although the trains tend to use the old London Underground seat frames, they have a range of interiors, which seem to be well-designed and comfortable.
I have been on Class 230 trains, with tables, a single toilet, onboard Wi-Fi, and electrical charging points.
Zero-Carbon
The trains are probably as near to zero-carbon, as any! Especially, if all the Fast Charge stations are powered by renewable electricity.
Remote Servicing
The trains have been designed for remote servicing.
Conclusion
All of these qualities lead me to think, that an ideal line in the UK could be the Far North Line, between Inverness and Wick and Thurso.
Although the train ticks a lot of boxes, it could well be too slow, It is also only a 160 mile route and not five-hundred
But there must be quite a few long, scenic lines in countries, where a passenger service needs to be added to a freight line, that perhaps serves a remote mining town.
Sweden and Norway are surely possibilities, but Finland is ruled out because it is Russian gauge.
Could the trains end up in parts of Africa, Canada and the United States?
Who knows?
Flywheel-Lithium Battery Hybrid Energy Storage System Joining Dutch Grid Services Markets
The title of this post, is the same as that of this article on Energy Storage News.
This is the introductory paragraph.
A hybrid energy storage system combining lithium-ion batteries with mechanical energy storage in the form of flywheels has gone into operation in the Netherlands, from technology providers Leclanché and S4 Energy.
These are some points from the article.
- The system contains 8.8MW / 7.12MWh of lithium-ion batteries.
- Six flywheels add up to 3MW of power.
- The 5,000kg KINEXT flywheel operates at 92% efficiency.
- The flywheels do not suffer from long-term degradation.
The article finishes with a discussion about the pros and cons of flywheel storage.
In the 1960s, when I worked at Enfield Rolling Mills, I heard stories of their 97-tonne flywheel on their main rolling mill for reducing copper wirebars to coils of wire for drawing into electrical wire for use in its myriad applications.
- Copper wirebars, were bars of refined copper about a metre long and perhaps ten centimetres square, which arrived at Enfield by barge from the London docks up the River Lea.
- The main rolling mill had arrived in Enfield, as reparations after the First World War. It had the Krupp trademark of three interlocked railway tyres all over it. It was probably built just after the start of the Twentieth Century.
- The flywheel was spun by an electric motor and the rolling mill itself, where wirebars snaked through a series of rollers of diminishing size, was driven from the flywheel.
- The arrangement meant that continuous power was supplied by the motor rather than intermittent power.
It was a fascinating process to watch, as the wire snaked through and was turned at each mill by an operator called a catcher, with a large pair of tongs. That was not a job for weaklings. The section I worked for, were always dreaming of automating the catching process. But I don’t think they ever did!
The flywheel was the source of legendary stories, many of which which have probably been exaggerated over the years.
One concerned its installation, where it was realised that there was no crane big enough to lift it from where it was delivered to the mill.
So the chief engineer, an Austrian Jew called Schimmatovich, devised a plan where men were used to roll it in to place. Like with the pyramids or in a concentration camp, where Shimmy had been incarcerated, as he said at the time.
It was successfully done on a Sunday morning, and after it was successfully secured, the Managing Director, who was called something like Freddy Pluety, suggested everybody join him in the Sports and Social Club for a drink.
So Freddy led a crocodile of perhaps a hundred across the road and walked into the Club, where the steward was just shutting up. Freddy ordered the drinks, but was told No! So Freddy picked him up and sat him on the bar. Freddy then noticed there were two very large and thirsty men on either side, so he said to them, “Are you going to hit him first or am I?”
They all got their drinks.
There must be many legendary industrial stories like this, that have been forgotten.
