National Express Deploys Hydrogen Double-Deckers In The West Midlands
The title of this post, is the same as that of this article on Renewable Energy Magazine.
This is the first paragraph.
National Express has deployed 20 hydrogen double-decker buses purchased by Birmingham City Council, serving West Midlands route 51 to Walsall via Perry Barr from 6th December 2021– the only hydrogen buses operating in England outside London.
The buses are from Wrightbus.
The article also says this about the source of the hydrogen.
The council are also collaborating with ITM, who are producing and dispensing the hydrogen fuel from the new re-fuelling hub at Tyseley Energy Park.
This is surely the way to do it. Hydrogen buses with a local source of freshly-picked hydrogen.
Decommissioned Audi EV Batteries Used In 4.5MWh Stationary Energy Storage System In Germany
The title of this post, is the same as that of this article on Energy Storage News.
These are the first two paragraphs of the article.
Used lithium-ion batteries taken from carmaker Audi’s electric vehicles (EVs) have been repurposed into a ‘second-life’ stationary energy storage system by energy company RWE at a project in Herdecke, Germany.
RWE has deployed the system, which has a capacity of around 4.5MWh, at the site of its pumped hydro energy storage (PHES) plant at Hengsteysee reservoir in the North-Rhine Westphalia region of north-west Germany.
The Hengsteysee looks to be a well-designed reservoir, as it provides four functions.
- Functions as the lower reservoir of the Koepchenwerk pumped-storage plant
- Performs biological purification of water from the Lenne
- Deposit of sediment from the Lenne
- Venue for water sports and tourism
This Google Map shows the Hengsteysee.
More details of the Koepchenwerk pumped-storage plant is given on this page on Power Technology.
- It has a generating capacity of 153 MW.
- The gross head is 145.5 metres.
- The storage capacity is around 0.6 GWh.
It is not the largest of pumped-storage plants, but Germany seems to have a lot of smaller ones like this and in total they have more than we do.
Transformer Deliveries Mark Major Milestone For Braybrooke Substation Project And The Midland Main Line Upgrade
The title of this post, is the same as that of this press release from National Grid.
The press release says this.
Since early 2021 National Grid Electricity Transmission (NGET) has been building a new electricity substation near Braybrooke, on the outskirts of Market Harborough in Leicestershire.
The new substation, once complete, will form a vital part of electrical infrastructure to support Network Rail’s electrification of the Midland Main Line.
Following months of hard work, the project has reached a major milestone, as the engineering team have taken delivery of two new transformers.
The transformers arrived during November and were delivered via an access road off Kettering Road built to ensure construction traffic avoids the areas of Market Harborough and Braybrooke. Weighing an impressive 100 tonnes, they will now be installed at the substation over the coming months.
This Google Map shows the access road.
Note.
The main A6 road running across the top of the map.
Kettering road leads off it into Market Harborough.
The Midland Main Line running across the bottom of the map.
The access track runs between the two.
This enlargement of the South East corner of the map shows the 400 kV overhead transmission line.
Note that the shadows give away two 400 kV pylons.
Will the sub-station be built in the smaller rectangular field?
How Many Sub-Stations Will Be Needed For The Midland Main Line Electrification?
I seem to remember that the Great Western Main Line to Cardiff was electrified with just three sub-stations, London, Cardiff and one in the middle and the London one is shared with Crossrail.
So I suspect that the feed of electricity may only need one further substation at the Northern end.
Conclusion
It does seem that National Grid have planned this well.
I suspect, bringing in the transformers didn’t cause too much disruption and the route gives good access to the overhead line.
Leicester Station – 4th Jan 2022
Leicester station has a Grade II Listed frontage.
Note.
- It is an impressive Victorian station.
- The station building is on a bridge over the tracks.
- The station is also on one of the main roads through Leicester.
- The road layout is very complicated.
This 3D Google Map, shows an aerial view of the station.
Note.
- There four platforms, which are numbered 1-4 from the left.
- The expresses between London and Derby, Nottingham and Sheffield use the two middle tracks.
- Other main line and East-West services use the outside platforms.
- There is an avoiding line for freight services.
This second 3D Google Map, shows an enlargement of the frontage of the station.
There are plans to increase the capacity of the station.
A fifth platform will be added.
Three miles of quadruple track will be be built South of the station.
The Midland Main Line is also to be electrified.
This second set of pictures shows the platforms at Leicester station.
Note.
- The tunnels under the road and the station entrance.
- They are not very large.
- There are five tracks.
It is going to be a tight squeeze to electrify under the bridge.
Midland Main Line Electrification – 4th Jan 2022
I took these pictures from the train today, as I went to Leicester.
Note.
- We overtook the Class 360 train to Corby, just before it left the main line at Kettering North junction.
- Once past Kettering North junction, the Midland Main Line is only two tracks as far as Leicester station.
- A lot of the gantries on the two slow lines seem tall.
- At least twenty gantries had been installed North of the junction.
Some of the new gantries looked to be lighter than those South of the junction, but then they are only supporting electrification for two tracks, rather than four.
This Google Map shows the junction.
In this section, my train overtook the train to Corby.
- The track going North-West goes to Leicester.
- The track going North-East goes to Corby.
- The track going South goes to Kettering.
- It looks like to the West of the Midland Main Line is a large electricity sub-station.
In the tenth of my pictures you can see the three vertical poles opposite the sub-station, which can be picked out in the map.
The Proposed Mid-Cornwall Metro
In the January 2022 Edition of Modern Railways, there is this description of the Mid-Cornwall Metro.
This would see an hourly service shuttling between the north and south coasts of the county and linking the main population centres at Newquay, St Austell, Truro and Falmouth. This would become the main service on the Newquay branch, and it would take over one of the twice-hourly services on the Falmouth branch, with the other service being a Truro to Falmouth shuttle as now.
Facilitating the Metro idea will be the latest phase of the modernisation of signalling in Cornwall, which will see the upgrade of a level crossing near Truro. Other infrastructure work required is a new passing loop on the Newquay branch at Tregoss Moor and restoration of a second platform face at the terminus at Newquay.
A business case was due to be submitted to the Department for Transport before Christmas 2021.
These are a few thoughts.
The Current Timings
If you look at the distances and timings of the various sections they are as follows.
- Newquay and Par – Five stops – 20.8 miles – 49-52 minutes
- Par and Truro – One stop – 19 miles – 22 minutes
- Truro and Falmouth Docks – Four stops – 11.8 miles – 24 minutes
Note.
- It appears that the Newquay to Par service is three minutes quicker than the other way.
- There will be a reverse at Par, which could take three minutes.
- The Par and Truro times were either GWR Castles or Class 802 trains.
The total time is 98-101 minutes and the total distance is 51.6 miles
Possible Timing
Consider.
- For the ease of timetabling and operation, it is probably best that a round trip between the two Newquay and Falmouth Docks takes an exact number of hours.
- The operating speed between Par and Truro is 75 mph and it is only 50 mph elsewhere.
- Turnround time at Newquay is five minutes.
- Turnround time at Falmouth Docks is 4-6 minutes
For these reasons, I doubt that much improvement could be made on the fastest time of 98 minutes. Certainly, a round trip of three hours would appear impossible.
But a round trip time of four hours would be very sensible.
However, there would be a turnround time of between 19-22 minutes at each end of the route.
This time might seem overly long, but it would be ideal for charging a battery-electric train.
How Many Trains Would Be Needed?
As the round trip will be four hours and an hourly service is needed, there will be a need for four trains to run the service, with the addition of probably two extra trains to allow for one in maintenance and one covering for any breakdowns.
Could The Mid-Cornwall Metro Use Battery-Electric Trains?
This Hitachi infographic shows the specification of the Hitachi Regional Battery Train.
Note
- The range of ninety kilometres is fifty-six miles and a longer distance than Newquay and Falmouth Docks.
- The operating speed of 90-100 mph is ideal.
- The time needed for a full charge at either end is within the timetable, I calculated earlier.
Hitachi Regional Battery Trains would be ideal for working the Mid-Cornwall Metro with a full charge at both ends of the route.
I have used my virtual helicopter to explore the Cornish Main Line between Par and Truro.
If it was decided to electrify the Cornish Main Line between Truro and Par, this could be an alternative way to charge the trains.
- The Mid-Cornish Metro trains should be able to do a return trip to Newquay and Falmouth Docks from the main line without charging at the two terminal stations.
- The electrification would be able to charge battery-electric Class 802 trains between Plymouth and Penzance.
But the extra infrastructure works to raise nine road bridges and several footbridges might blow the budget.
Where Would The Trains Be Serviced?
Great Western Railway has depots at both Penzance and Plymouth and with perhaps a charger at Truro and/or Par stations, the trains should be able to get to either depot at the end of the day.
Trains To Newquay
Wikipedia says this about the services to Newquay station.
The service is irregular with typically one train around every two hours.
As well as the local service, the station handles a number of long-distance trains in the summer. These services include Great Western Railway trains from London Paddington and CrossCountry trains from the North of England and the Scottish Lowlands, which do not stop at intermediate stations between Par and Newquay. On Sundays, there are some local trains and a small number of intercity services. As well as the weekend through trains, in peak summer months there is also a Monday-Friday through Great Western Railway intercity service to and from London, but local trains continue on these days too. Traditionally, there was no Sunday service in the winter, even in the ‘golden age’ between both of the 20th century’s world wars, but the line has a service of three trains each way on Sundays from 11 December 2011.
The Mid-Cornwall Metro will at least come with an hourly service.
But this will mean, that to run other services to the station with the hourly Metro will mean that a second platform will be needed.
I discuss the improvements needed in Beeching Reversal – Transforming The Newquay Line.
This is a quirky video, which describes an architect’s plans for the station.
It is the sort of simple solution, that I like.
Conclusion
I believe that a small fleet of Hitachi Regional Battery Trains could create an iconic Metro for Cornwall, that would appeal to both visitors and tourists alike.
CargoBeamer Operates Lane Between Kaldenkirchen And Perpignan
The title of this post, is the same as that of this press release from CargoBeamer.
It has this sub-title.
New Route Starting In January 2022
These two paragraphs form the body of the release.
The logistics service provider CargoBeamer is expanding its intermodal network from the beginning of next year. Between Kaldenkirchen in Germany and Perpignan near the French-Spanish border, goods will be transported environmentally friendly by rail from January 10, 2022. The patented CargoBeamer system enables all kinds of semitrailers, containers, P400 trailers, refrigerated and tank trailers, and other types of goods to be transported by train without requiring any additional conversions for forwarders.
At the start in January, initially three trains will run weekly in each direction. From mid-February, the frequency will increase permanently to five round trips per week. CargoBeamer will collaborate with DB Cargo France (formerly Euro Cargo Rail) as its traction partner. The new Franco-German route is the company’s sixth connection overall, with five of the six lines having been added to the network in the past six months.
They certainly seem to be adding routes frequently.
How Do Trailers Get Between Ashford And Calais?
They obviously go through the Channel Tunnel, but what happens on each side of the Channel?
Is the trailer fixed to a tractor unit at the Ashford and Calais terminals and then driven onto the freight shuttle?
This video contains an interview with Nicolas Albrecht from CargoBeamer
What Happens When The Wind Doesn’t Blow?
In Future Offshore Wind Power Capacity In The UK, I analysed future offshore wind power development in the waters around the UK and came to this conclusion.
It looks like we’ll be able to reap the wind. And possibly 50 GW of it!
The unpredictable nature of wind and solar power means that it needs to be backed up with storage or some other method.
In The Power Of Solar With A Large Battery, I describe how a Highview Power CRYObattery with a capacity of 500 MWh is used to back up a large solar power station in the Atacama desert in Chile.
But to backup 50 GW is going to need a lot of energy storage.
The largest energy storage system in the UK is Electric Mountain or Dinorwig power station in Wales.
- It has an output of 1.8 GW, which means that we’d need up to nearly thirty Electric Mountains to replace the 50 GW.
- It has a storage capacity of 9.1 GWh, so at 1.8 GW, it can provide that output for five hours.
- To make matters worse, Electric Mountain cost £425 million in 1974, which would be over £4 billion today, if you could fine a place to build one.
But it is not as bad as it looks.
- Battery technology is improving all the time and so is the modelling of power networks.
- We are now seeing large numbers of lithium-ion batteries being added to the UK power network to improve the quality of the network.
- The first Highview Power CRYObattery with an output of 50 MW and a capacity of 250 MWh is being built at Carrington in Manchester.
- If this full size trial is successful, I could see dozens of CRYOBatteries being installed at weak points in the UK power network.
- Other battery technology is being developed, that might be suitable for application in the UK.
Put this all together and I suspect that it will be possible to cover on days where the wind doesn’t blow.
But it certainly will need a lot of energy storage.
Gas-Fired Power Stations As A Back Up To Renewable Power
Last summer when the wind didn’t blow, gas-fired power stations were started up to fill the gap in the electricity needed.
Gas-fired power-stations normally use gas turbines similar to those used in airliners, which have a very fast startup response, so power can be increased quickly.
If you look at the specification of proposed gas-fired power stations like Keadby2, they have two features not found in current stations.
- The ability to be fitted in the future with carbon-capture technology.
- The ability to be fuelled by hydrogen.
Both features would allow a gas-fired power-station to generate power in a zero-carbon mode.
Carbon Capture And Storage
I am not in favour of Carbon Capture And Storage, as I believe Carbon Capture and Use is much better and increasingly engineers, researchers and technologists are finding ways of using carbon-dioxide.
- Feeding to tomatoes, salad vegetables, soft fruits and flowers in greenhouses.
- Producing meat substitutes like Quorn.
- Producing sustainable aviation fuel.
- An Australian company called Mineral Decarbonation International can convert carbon dioxide into building products like blocks and plasterboard.
This list will grow.
Using or storing the carbon-dioxide produced from a gas-fired power station running on natural gas, will allow the fuel to be used, as a backup, when the wind isn’t blowing.
Use Of Hydrogen
Hydrogen will have the following core uses in the future.
- Steelmaking
- Smelting of metal ores like copper and zinc
- As a chemical feedstock
- Natural gas replacement in the mains.
- Transport
Note that the first four uses could need large quantities of hydrogen, so they would probably need an extensive storage system, so that all users had good access to the hydrogen.
If we assume that the hydrogen is green and probably produced by electrolysis, the obvious place to store it would be in a redundant gas field that is convenient. Hence my belief of placing the electrolyser offshore on perhaps a redundant gas platform.
If there is high hydrogen availability, then using a gas-fired power-station running on hydrogen, is an ideal way to make up the shortfall in power caused by the low wind.
Conclusion
Batteries and gas-fired power stations can handle the shortfall in power.
Foot Crossing Obstacle Detection Using AI
The title of this post, is the same as that as this article on the Railway Gazette.
This is the introductory paragraph.
Seibu Railway is to start testing a newly-developed AI-assisted warning system for detecting obstacles on foot crossings at two stations on the Ikebukuro Line in the suburbs of Tokyo.
The article is a detailed description of how the Japanese are using technology to make foot crossing a lot safer.
I can see applications for this technology not just on the rail system, but in other situations as well.
Green Ships Ahoy Along Vital Corridors
The title of this post, is the same as that of this article on 7 News Australia.
These are the first two paragraphs.
Australia’s biggest miners are preparing for a day of reckoning.
Shipping accounts for two to three per cent of global greenhouse gas emissions so manufacturers and retailers are no longer just considering what appears in national targets.
The article then goes on to explain how the big mining companies are cutting their emissions.
This paragraph illustrates how important mining and shipping is to Australia.
Resources and energy earnings passed $300 billion for the first time in 2020-21 and will surge towards $400 billion in 2021-22, according to December figures.
Hence the big need for ships fuelled by lower carbon fuels.
