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.
New Bridge In Tottenham Marks The Beginning Of Restoring A Line Lost During The Beeching Era
The title of this post says it all and is the same as this article on Rail Professional.
Some might argue that Beeching got it wrong!
My feelings though are the politicians and British Rail managers of the day generally didn’t have any vision about how the railways should be simplified to on the one hand save money and on the other perhaps create paths, cycleways and leisure facilities, for the good of everyone.
Harold Wilson’s view that everybody would have their own car and the railways were finished didn’t help either.
The Lea Valley was my childhood playground and I’d regularly cycle to the area. But unlike now, much was closed to the public.
This Google Map shows the location of the bridge.
Note.
- The railway line is the West Anglia Mail Line, running South from Tottenham Hale stations.
- The bridge carrying the Easter pair of tracks is being replaced.
- Tottenham South Junction is North of the bridge and the line going West is the Tottenham South Curve, that links the West Anglia Main Line to the Gospel Oak to Barking Line.
- The Markfield Beam Engine is to the West.
- The Walthamstow Wetlands are to the East.
The area will get even more complicated in the future, when Crossrail 2 is built.
These are various pictures of the bridge site, taken on different dates
The bridge will be an important link in the development of the railways in the area.
West Anglia Route Improvement – Meridian Water, Road Traffic And Level Crossings – 1st March 2017
This map from the Meridian Water web site shows the area of Meridian Water outlined in red.
And this Google Map shows the Lea Valley from the North Circular Road in the North almost to Tottenhsm Hale in the South.
Note.
- Tesco and IKEA are in the middle of the Meridian Water site with the West Anglia Main Line and the main North South road to their West.
- The River Lea and the River Lea Navigation Canal pass between the Meridian Water site and the Banbury Reservoir.
With the building of Meridian Water, traffic in the area is only going to get worse.
The main North-South route shown in the second map starts North of Enfield Lock, where it has rather dodgy connections to the M25 and is generally a single carriageway road, all the way to the Tottenham Hale Gyratory, where traffic is heavy at all times.
One problem is going or coming West from this North-South route, as vehicles need to cross the West Anglia Main Line.
Starting from the North, the crossings of the railway are as follows.
- A level crossing at Enfield Lock station.
- A level crossing at Brimsdown station.
- A bridge for the A110
- A bridge at Conduit Lane, just North of the current Angel Road station.
- The North Circular Road, which is not well-connected to the North-South route.
- A bridge at Leeside Road, just South of the proposed site of Meridian Water station.
- A level crossing at Northumberland Park station.
Another bridge over the railway delivers you into the jams at Topttenham Hale.
STAR is currently envisaged to provide a seven-day-a-week services of four trains per hour (tph) between Angel Road and Stratford with calls at Northumberland Park, Tottenham Hale and Lea Bridge stations.
However the current local service up the Lea Valley from Stratford goes to Hertford East and Bishops Stortford stations with a rather erratic stopping pattern at stations North of Tottenham Hale.
So will STAR be based on these services or a separate train turning back at Meridian Water station?
But whatever happens it will increase the number of trains through Northumberland Park station.
It has now been announced in the last few weeks, that the level crossing will be closed.
Drivers wanting to go across the level crossing, following the closure will now do one of the following.
- Go South and over the railway to Tottenham Hale.
- Go North and cross the railway on the Leeside Road bridge.
They could always use the train.
I think the following would help mitigate the loss of the crossing.
- Some road improvement at the junction of Leeside Road and the North-South road.
- A decent pedestrian route between the new Meridian Water station and Glover Drive for Tesco and IKEA.
- The STAR service going North from Meridian Water station, as well as South to Stratford.
Hopefully, it will all be clear by the end of 2018.
West Anglia Route Improvement – Cheshunt Station – 26th February 2017
I took these pictures at Cheshunt station.
This Google Map shows the layout of the station.
The station is very much a gateway to the Lea Valley Country Park and it could be difficult to find a by-pass for the level crossing.
I think putting two extra tracks through the station could be difficult.
- ,The space is a bit narrow.
- The level crossing will probably have to stay.
- A lot of express trains stop, so that passengers can change to the London Overground.
Perhaps the solution is to do something like the following.
- Extend the London Overground service to Broxbourne station, where there is space for extra platforms.
- Stop fast services calling at Cheshunt station.
- Move the two slow tracks Westward a bit, to create space for the two new lines on the Eastern side.
I also think, that extending the Overground to Broxbourne would make Broxbourne station an even better interchange.
From Walthamstow To Hackney
The space in the East of London up the Lea Valley between Walthamstow and Hackney is all grass, scrub, reservoirs, canals, rivers and railways.
These pictures were taken on a train between Walthamstow James Street and Clapton stations.
It is a very underused area and lies just to the south of the proposed Walthamstow Wetlands. The only development that will happen here is to reinstate the Hall Farm Curve to enable trains from Walthamstow and Chingford to join the Lea Valley Line to Lea Bridge and Stratford. It will probably end up though, ringed by high-rise housing, like you can see along the River Lea.
London is a surprising city. Soon it will be a City with a world-class nature reserve just a few minutes from the business heart of the City, This is a Google Map of the area.
Note the two rail lines crossing in the middle. The route of the Hall Farm Curve can be made out, as it hugs the boundary of the unmanaged area.
At the top of the picture you can see the filter beds of Thames Water’s giant water factory, that provide a lot of London with water using the massive reservoirs of the Lea Valley, some of which will form part of the Walthamstow Wetlands.
If you take a train from Liverpool Street to Stansted Airport or Cambridge, you’ll come over the River Lea and then take the curve to join the main line before passing through the Walthamstow Wetlands and stopping at Tottenham Hale.
London Has A New Island And Bridge
City Island is a housing development in a bend of the River Lee. The island has been connected to Canning Town, by a new bridge, that was lifted in place by the UK’s largest mobile crane.
Unfortunately, by the time I got there the bridge was in place and the crane was virtually dismantled.
Visiting The New Park
I finally, got to view the new Queen Eizabeth Olympic Park yesterday.
It is obviously not finished by any means, but it is impressive.
It also opens early in the morning at 06:00 and closed fairly late.
I travelled to the park, by getting a 588 bus from Hackney Wick, to the stop by the Copper Box. At present, the information on the bus isn’t working in the area of the park, but I suspect it will be in a few days.
An Attempt To Find The New Olympic Park
On Monday, I attempted to find the new Queen Elizabeth Olympic Park, which the BBC announced had opened.
After a very unwelcoming walk from Eastfield, I found the entrance and it was crawling in security, who said it opened later.
Information and maps were also a bit lacking about the buses, but eventually I got a 588 to Hackney Wick, from where I got a 30 home.
