WyRefueler—The Mobile Hydrogen Filling Station

The title of this post, is the same as that of the product page on the Wystrach web site.

This is the introductory paragraph.

It’s transportable, energy-efficient, and user-friendly: the WyRefueler is here! The mobile hydrogen refueling station is suitable for wide range of refueling applications. Besides filling trucks, buses, and trains with hydrogen, it can be used for vehicles on construction sites, in ports, or at airports. The WyRefueler enables emission-free logistics and intralogistics—and there’s no limit to where it can be deployed!

It looks a sensible concept, but it is only a tank system, without an electrolyser.

It would surely be ideal for a company to trial a few hydrogen vehicles, before deciding on a permanent installation.

Graffiti Vandals Paralyse Island Line Service

The title of this post, is the same as that of this article on Railnews.

This is the first paragraph.

The Island Line timetable was suspended on Monday morning, after the only serviceable train on the route was sprayed with graffiti. Passengers were being diverted to buses until the graffiti could be removed.

I can’t understand the motives of people who spray graffiti and I hope that the culprits are found and given time in one of the Isle of Wight’s prisons.

Fighting My Way Through The Covids

I owe it to the memory of my great-great-great-grandfather; Robert, who arrived in this country around 1800, from Konigsberg in East Prussia, that I fight my way through the covids.

He had to leave Konigsberg because he was eighteen, male and Jewish! Unless, you were a member of a privileged family, you had to leave. As he had just finished his apprenticeship to be a tailor, he at least had a trade and could carry the tools he needed in a small case.

He became a tailor in Bexley and lived to a good age. I am also sure, that he contributed coeliac disease to the family’s gene pool.

In this post, I will talk about various topics, as I fight my way through to normality.

On the mother’s side of the family, the male line in Huguenot, who probably arrived about 1750.

Did I Fall Because Of A Blood Pressure Problem?

I had a fall in my bedroom, a couple of months ago, as I wrote about in An Accident In My Bedroom.

My GP thinks I might have a blood pressure problem, so I’m now taking my blood pressure sitting down and then standing up for five minutes before taking it again.

These are my readings.

  • September 28th – 08:00 – 140/73/77 – 140/73/60

Note.

  1. The first reading is sitting down and the second is after standing up for five minutes.
  2. My blood pressure meter isn’t the best.
  3. I didn’t note the times, when I started.
  4. The third reading is taken about four minutes later.

I don’t know anything about understanding these readings.

Managing My INR

My GP and I have agreed that I should be on 3.5 mg. of Warfarin a day to control my INR.

  • So I alternate between 3 and 4 mg.
  • I also test my INR every two days.

These are my figures for the last few days, with my Warfarin dose.

  • September 1st – 4 mg – N/R
  • September 2nd – 3 mg – 2.5
  • September 3rd – 4 mg – N/R
  • September 4th – 3 mg – 2.7
  • September 5th – 4 mg – N/R
  • September 6th – 3 mg – 2.8
  • September 7th – 3 mg – N/R
  • September 8th – 4 mg – 2.4
  • September 9th – 3 mg – N/R
  • September 10th – 4 mg – 2.3
  • September 11th – 3 mg – 2.7
  • September 12th – 4 mg – N/R
  • September 13th – 3 mg – 2.5
  • September 14th – 4 mg – N/R
  • September 15th – 4 mg – 2.2
  • September 16th – 3 mg – N/R
  • September 17th – 5 mg – 2.2
  • September 18th – 3 mg – 2.8
  • September 19th – 4 mg – N/R
  • September 20th – 4 mg. – 2.5
  • September 21st – 3 mg – N/R
  • September 22nd – 4 mg – 2.2
  • September 23rd – 3 mg – 2.3
  • September 24th – 4 mg – N/R
  • September 25th – 3 mg – 2.4
  • September 26th – 4 mg – N/R
  • September 27th – 4 mg – 2.1
  • September 28th – 3 mg – 2.4

Note.

  1. If the INR is 2.5 or greater, I take 3 mg that day and 4, the next.
  2. If it’s less than 2.5, I take 4 mg that day and 3 the next,
  3. I also check the 30 day average of my Warfarin dose and currently it is 3.6.

One advantage about Warfarin, is the degree of control, you have of your INR.

A couple of years ago, I needed to have a small operation on my mouth.

The surgeon wanted to use an anaesthetist to boost the bill.

  • So I said, what INR would be safe and he said 2.1!
  • In the end I reduced it, by not taking four mg of the drug.
  • After the successful operation, I brought it back up to 2.5, by taking an extra four mg.
  • I suspect it cost me a tenner for the extra strips!

Good value and I avoided the lottery of anaesthesia.

I’m Drinking A Lot

In a four-hour period a few days ago, I drank two litres. Is that excessive?

It did include half a unit of alcohol, but was mainly mugs of tea.

And I still felt the need to drink more.

General Health

Like most coeliacs, I know on a gluten-free diet, I’m doing fairly well in the pandemic.

Not one of us has had a severe dose of the covids. But then I’ve never had flu since I went gluten-free and I’ve only had a flu jab since 2005.

Could this be related to the fact, that the gluten-free diet gives us a strong immune system and seems to protect us from cancer, according to research by Joe West at Nottingham University?

Electrification Plans For Line Between Fife And Clackmannanshire

The title of this post, is the same as that of this article on Rail Technology News.

This is the introductory paragraph.

The next stage of development work is due to begin for Network Rail engineers between Alloa and Longannet, which could see passenger services return between Clackmannanshire and Fife.

The article also makes these points.

  • As part of the Scottish Government’s decarbonisation plan, it is hoped the former freight line will be electrified.
  • Engineers will be conducting survey work and site and geological investigations.
  • Three new stations are also hoped to be introduced at Clackmannan, Kincardine and Longannet.
  • The work is also hoping to bring a two trains per hour (tph) passenger service between Alloa and Longannet.

There will be a lot of surveying and planning before work starts.

Existing Rail Routes And Services In The Area

These are the current routes and services in the area.

Alloa Station

Alloa station was closed in October 1968, when Harold Wilson was Prime Minister and re-opened in 2008.

Wikipedia says this about the re-opening.

Under Scottish Executive funding, the line between Stirling and Alloa was reopened to both passenger and freight traffic, with a key benefit being a reduction in congestion on the Forth Railway Bridge.

The basic train service is an hourly service to Stirling and Glasgow run by a Class 385 train.

Journey times are as follows.

  • Alloa and Stirling – 9-15 minutes
  • Alloa and Glasgow Queen Street – 45 minutes

Trains seem to take about twelve minutes to turnround at Alloa station.

This Google Map shows Alloa station.

Note.

  1. The station currently only has one platform.
  2. A second line is already laid through the station and although, it is not electrified, the gantries are positioned to electrify the second track.
  3. The two tracks merge into one to the West of the station.
  4. All passenger trains currently use the Southern platform.

This picture shows the station, just before the electric train services started.

The station also must have one of the largest station shops in the UK, which is an Asda superstore.

The Kincardine Line

The Kincardine Line is the one proposed for electrification.

  • It is currently, a freight-only route, that was re-opened to serve Longannet power station.
  • At Alloa station, it is an extension of the route from Stirling.
  • It may be connected to the new Talgo factory at Longannet, that I wrote about in A Spaniard In The Works!, as the factory will surely need electrified rail access, if any electric trains for the UK are to be built or serviced there.
  • The line passes through Clackmannan, Kincardine and Longannet.

As the route used to handle long coal trains, could it handle a 200 metre long classic-compatible high speed train, that Talgo might build for High Speed Two at Longannet?

The Fife Circle Line

According to Wikipedia, the Fife Circle Line is the local service North from Edinburgh, that goes in a long loop through Fife.

This map from Wikipedia shows the stations on the Fife Circle Line.

Note.

  1. The route is double-track.
  2. The route is not electrified.
  3. The train service is generally two trains per hour (tph) in both directions.
  4. The distance from Dalmeny to Glenrothes with Thornton via Cowdenbeath is 22.3 miles
  5. The distance from Dalmeny to Glenrothes with Thornton via Kirkcaldy is 21.4 miles
  6. Trains appear to wait between three and seven minutes at Glenrothes with Thornton before returning to Edinburgh by the alternate route.

The map doesn’t show the connection with the Kincardine Line at Dunfermline Town station.

This Google Map shows the Fife Circle Line, through Dunfermline Town station.

Note.

  1. Dunfermline Town station at the top of the map, is indicated by a station sign.
  2. The Northbound Fife Circle Line to Cowdenbeath leaves the map in a North-Easterly direction.
  3. The Southbound Fife Circle Line to Rosyth and Dalmeny, runs behind the building that looks strangely like a signpost and leaves the map in a Southerly direction
  4. There is a junction, called Charlestown Junction, where the Kincardine Line joins the Fife Circle Line.

This Google Map shows Charlestown junction.

Note.

  1. The Fife Circle Line is double-track.
  2. The Kincardine Line is only single-track.
  3. Trains must enter and leave the Kincardine Line from a Northerly direction.
  4. There is a cross-over between Charlestown junction and Dunfermline Town station.

The Google Map shows Dunfermline Town station to a larger scale.

It looks like fitting in an additional platform could be difficult.

Hitachi’s Regional Battery Train

I am introducing this train into the discussion, as the train might be an alternative to electrifying the Kincardine Line.

This infographic from Hitachi, describes the train.

Note that 90 kilometres is fifty-six miles.

From what Hitachi have said, it is likely that Class 385 trains, as used by ScotRail could be fitted with batteries and become a version of the Regional Battery Train.

  • They could be three or four cars.
  • They could work in pairs.
  • They would have a 100 mph operating speed.

Even on battery power, they might save time, against the current diesel units working services in Scotland.

Regional Battery Trains And The Fife Circle Line

This map shows the rail system to the West of Edinburgh.

All lines except for the route through South Gyle and Edinburgh Gateway stations are electrified.

A train going round the Fife Circle Route would do the following legs.

  • Edinburgh and South Gyle – 4.5 miles – All but one mile electrified.
  • South Gyle and Dalmeny – 5 miles – Not electrified.
  • Dalmeny and Glenrothes with Thornton via Cowdenbeath – 22.3 miles – Not electrified
  • Glenrothes with Thornton and Dalmeny via Kirkaldy – 21.4 miles – Not electrified
  • South Gyle and Dalmeny – 5 miles – Not electrified.
  • Edinburgh and South Gyle – 4.5 miles – All but one mile electrified.

This gives the following  totals

  • Not electrified via Cowdenbeath – 28.3 miles
  • Not electrified via Kirkcaldy – 27.4 miles
  • Round trip – 62.7 miles
  • Electrified – 7 miles

It would be very tight for a Regional Battery Train to do a round trip of 62.7 miles consistently with a range of just 56 miles, with only seven miles of electrification at the Edinburgh end.

But if charging at Glenrothes with Thornton were added, this would enable the trains to start out on the near thirty miles without electrification with full batteries from both ends. They would be unlikely to run out of power halfway.

Regional Battery Trains And The Levenmouth Rail Link

In Scottish Government Approve £75m Levenmouth Rail Link, I wrote about the five-mile long Levenmouth Rail Link, and how it could be run by battery trains.

Since I wrote that post, Hitachi have announced their Regional Battery Train.

  • If these were used on the route, they would join the Fife Circle at Thornton North Junction.
  • I estimate that the track distance that is not electrified between Leven and Edinburgh via Thornton North junction, is about thirty-five miles, whether the trains go via Glenrothes with Thornton and Cowdenbeath or Kirkcaldy,

As with the Glenrothes with Thornton service, if there was charging at at both ends, the route would be within comfortable range of Hitachi’s Regional Battery Trains.

Regional Battery Trains And The Kincardine Line

Rough distances by road along the Kincardine Line are as follows.

  • Alloa and Longannet – 8 miles
  • Alloa and Dunfermline Town – 15 miles
  • Alloa and Glenrothes with Thornton via Dunfermline Town – 30 miles

This would surely mean that Regional Battery Trains could work all these routes.

  • Trains would leave Alloa with full batteries after charging on the electrification from Edinburgh, Glasgow and Stirling.
  • Longannet and Dunfermline Town could be served by a return trip from Alloa on batteries.
  • Charging at the Fife end would only be needed for the Glenrothes with Thornton route.

Some might think, that this would mean the Kincardine Line needn’t be electrified. But I feel Talgo will want an electrified route to their factory, so trains can move in and out under electric power.

The Design Of The Kincardine Route

These are my thoughts on various topics, taken vaguely from West to East.

Alloa Station

Alloa station already has two tracks, but as the plans envisage two tph between Alloa and Longannet, I am fairly certain a second platform will be needed at Alloa.

There is certainly space, but the station would also need a bridge for passengers.

Perhaps, the architects will use something like this bridge design.

This step-free bridge won the Network Rail/RIBA Footbridge Design Competition, but has yet to be deployed on the UK rail network.

Will the two tph service between Alloa and Longannet continue West to Stirling?

I suspect the track layout with a passing loop at Cambus to add to the one at Alloa station will give sufficient track capacity, so I suspect there will be two tph between Longannet and Stirling.

Would both services terminate at Glasgow or would one go to Glasgow, with the other to Edinburgh?

Clackmannan Station

The small town of Clackmannan has a population of about 3,500 and used to be served by Clackmannan and Kennet station, which closed in 1930.

This Google Map shows the town of Clackmannan.

Note.

  1. The Kincardine Line runs between the North West and South-East corners of the map, through the centre of the town.
  2. The original Clackmannan and Kennet station was to the South-East of this map.

This second Google map shows an enlargement of part of the town.

It would appear that there is space for a station.

  • Only a single platform would be needed.
  • What is the plan for the development site?

It could be designed as a walkway station, as has been proposed for Magor and Undy station in Wales.

Kincardine Station

The Kincardine Line runs between the small town of Kincardine and the River Forth and Kincardine station closed in 1930.

This Google Map shows the railway alongside the river.

Note.

  1. Kincardine Bridge crossing the Firth of Forth.
  2. The bridge can be used by pedestrians and cyclists.
  3. The Kincardine Line running along the river.
  4. It is not a long walk between the town centre and the railway.
  5. The blue dot to the South of the road junction marks the start of the Fife Coastal Path, which is over a hundred miles long.

Will the station be built in this area?

Longannet Station

Longannet power station was at the time of closure in 2016, the third-largest coal-fired power station in Europe.

This Google Map shows the site.

Note.

  1. The actual power station is in the middle.
  2. To the West is the coal store.
  3. The Kincardine Line comes along the river and then loops North of the power station, before curving down to the river to go to the East.
  4. There appears to be two triangular junctions either side of the coal store with a loop around the store to allow delivery of coal.

This second Google Map shows between the power station and the coal store.

Note.

  1. The Kincardine Line running West-East across the map.
  2. The triangular junction connecting it to the loop line around the coal store.
  3. The coal conveyor that used to move coal from the store to the power station.

I’d certainly like to see the plans for the site, as it is one with a lot of potential.

  • There is space for a large rail-connected factory for Talgo.
  • The station could be placed at the most convenient place.
  • There is space for a two platform station to make sure a two tph service is possible.
  • There could be lots of housing and industrial units.
  • there could be waterside housing.
  • There could be a convenient rail service to Edinburgh, Glasgow and Stirling.

It could be a big development for the Central Belt of Scotland.

Onward To Dunfermline

I have followed the route to Dunfermline Town station in my helicopter and it doesn’t seem the most difficult of lines to reopen.

  • Unlike many lines like this, there doesn’t appear to be too many bridges or level crossings.
  • The connection to the Fife Circle Line looks to be adequate.

I have these thoughts.

  • Cn this section of the line, could more stations be added?
  • As the Fife Circle Line is not electrified, would battery electric trains be ideal?
  • Would turnround facilities be needed at Dunfermline Town stations.

But at the moment, the plan is only to go as far as Longannet.

Thoughts On The Stations

The stations would generally be very simple.

  • Alloa would be a two-platform station.
  • Longannet might need provision for a passing loop and a second platform, so extension to Dunfermline wouldn’t be difficult.
  • All other stations could be single platforms.
  • All stations would be step-free.

Only two-platform stations would need footbridges.

Final Thoughts On Electrification

Consider.

  • All services on the Fife Circle Line, Kincardine Line and the Levenmouth Rail Link could be run using Hitachi’s proposed Regional Battery Train, with a few charging facilities at selected stations.
  • Talgo will need an electrified line to Longannet
  • As Alloa and Dunfermline Town is only about 15 miles, a Regional Battery Train could run a return trip without recharging.

It would appear that only the single-track between Alloa and Longannet needs to be electrified.

Conclusion

This looks to be a good scheme.

Energy Storage Takes On Weird New Forms As Sparkling Green Future Takes Shape

The title of this post, is the same as that of this article on CleanTechnica.

The first section is entitled Gravity-Enabled Energy Storage Tested By Scotland’s Gravitricity and explains it well.

It then writes an interesting aside about pairing a Gravitricity system, with an idea from GE, in a section, which is entitled A Wind Power & Energy Storage Twofer, Maybe.

GE were proposing a lattice-style wind-turbine tower, so why not put a Gravitricity system inside?

Hence the maybe in the section title!

I can imagine an office or residential tower with a Gravitricity system built into the lift core in the centre of the building. Top the building with solar panels or wind turbines and you’re going some way towards a building that could be self-sufficient in energy.

Putting two and two together, so they add up to five, is the best way to improve efficiency.

The last section is entitled How To Do Energy Storage Without Any Energy Storage.

As I have never played a computer game, I don’t understand it, but it is based on research at two reputable universities; Delft University of Technology (TU Delft) in the Netherlands and Northwestern University in the US.

Conclusion

We will be seeing weirder and weirder ideas for energy generation and storage in the future.

France Devotes €30 Billion To Energy Transition

The title of this post, is the same as that of this article on PV Magazine.

This is the introductory paragraphs.

The French government has launched a new Covid-19 recovery plan that includes €30 billion to invest in the energy transition.

The top priority is the creation of a hydrogen economy, with €2 billion to be invested by the end of 2022 and €7.2 billion up to 2030. The money will be used for R&D activities and industrial electrolysis development projects.

The full plan for hydrogen will be published on September the 8th.

Other plans include.

  • €7 billion for building renovations.
  • €11 billion for the transport section.
  • 100,000 terminals for electric vehicles by 2021.

I feel, that they will need to do more to decarbonise the transport sector.

Running Battery Electric Trains Between London Marylebone And Aylesbury

This post was suggested by Fenline Scouser in a comment to Vivarail Targets Overseas Markets, where they said.

I have long thought that one UK application that would make sense is the Marylebone – Aylesbury via Harrow on the Hill service, the intermediate electrified section lending itself to full recharge on each trip. ? stabling facility at Aylesbury with overnight charging.

It does look to be an idea worth pursuing.

Current And Future Services

Currently, the services between London Marylebone and Aylesbury are as follows.

  • London Marylebone and Aylesbury via High Wycombe
  • London Marylebone and Aylesbury via Amersham
  • London Marylebone and Aylesbury Vale Parkway via Amersham

All services are one train per hour (tph)

In the future, it is planned to extend the Aylesbury Vale Parkway service to Milton Keynes, according to information I found on the East West Rail web site.

  • It looks like the service will go via High Wycombe, Saunderton, Princes Risborough, Monks Risborough, Little Kimble, Aylesbury, Aylesbury Vale Parkway, Winslow and Bletchley.
  • The service will have a frequency of 1 tph.
  • Time between Milton Keynes and Aylesbury is quoted as 33 minutes.
  • Time between High Wycombe and Milton Keynes is quoted as 63 minutes.

Will this leave the Marylebone and Aylesbury are as follows?

  • 1 tph – London Marylebone and Aylesbury via High Wycombe.
  • 2 tph – London Marylebone and Aylesbury via Amersham

Passengers between London Marylebone and Aylesbury would have the same service.

Distances

These are a few distances, of which some have been estimated.

  • London Marylebone and Harrow-on-the-Hill – 9.18 miles.chains

Hitachi’s Regional Battery Train

Hitachi’s Regional Battery Train, is the only battery electric train intended for the UK network for which a detailed specification has been released.

This infographic from Hitachi gives the specification.

Note that ninety kilometres is fifty-six miles.

I would suspect that battery trains from other manufacturers, like Bombardier, CAF and Stadler, will have a similar specification.

Battery Electric Trains Between London Marylebone And Aylesbury

I’ll take each possible route in turn.

London Marylebone And Aylesbury Via Amersham

The three sections of the route are as follows.

  • London Marylebone and Harrow-on-the-Hill – 9.23 miles – Not Electrified
  • Harrow-on-the-Hill and Amersham – 14.34 – Electrified
  • Amersham and Aylesbury – 15.29 miles – Not Electrified

Note.

  1. The total distance is 38.85 miles
  2. A typical service takes just under twenty minutes to travel between Harrow-on-the-Hill and Amersham. This should be enough to fully charge the batteries.
  3. A train going South from Harrow-on-the-Hill could reach London Marylebone and return.
  4. A train going North from Amersham could reach Aylesbury and return.

I am fairly confident, that a battery electric train, with the range of a Hitachi Regional Battery Train could work this route.

London Marylebone And Aylesbury Vale Parkway Via Amersham

The four sections of the route are as follows.

  • London Marylebone and Harrow-on-the-Hill – 9.23 miles – Not Electrified
  • Harrow-on-the-Hill and Amersham – 14.34 – Electrified
  • Amersham and Aylesbury – 15.29 miles – Not Electrified
  • Aylesbury and Aylesbury Vale Parkway – 2.31 miles – Not Electrified

Note.

  1. The total distance is 41.16 miles
  2. A typical service takes just under twenty minutes to travel between Harrow-on-the-Hill and Amersham. This should be enough to fully charge the batteries.
  3. A train going South from Harrow-on-the-Hill could reach London Marylebone and return.
  4. A train going North from Amersham could reach Aylesbury Vale Parkway and return.

I am fairly confident, that a battery electric train, with the range of a Hitachi Regional Battery Train could work this route.

London Marylebone And Aylesbury Via High Wycombe

The two sections of the route are as follows.

  • London Marylebone and High Wycombe- 28.14 miles – Not Electrified
  • High Wycombe and Aylesbury – 15.35 miles – Not Electrified

Note.

  1. The total distance is 43.50 miles
  2. There is no electrification to charge the trains.

A battery electric train, with the range of a Hitachi Regional Battery Train will need charging to work this route.

However, with charging at both ends, this would be a route for a battery electric train.

At the London Marylebone end, there are two possible solutions.

  • Electrify the station traditionally, together with perhaps the tracks as far as Neasden, where the routes split. Either 750 VDC third-rail or 25 KVAC overhead electrification could be used.
  • Fit fast charging systems into all the platforms at the station.

Note.

  1. Turnround times in Marylebone station are typically nine minutes or more, so using a charging system should be possible.
  2. Power for the electrification should not be a problem, as the station is close to one of London’s central electricity hubs at Lisson Grove by the Regent’s Canal.

The final decision at Marylebone, would be one for the engineers and accountants.

At the Aylesbury end, it should be noted that much of the under twenty miles of track between Princes Risborough and Aylesbury and on to Aylesbury Vale Parkway and Calvert us single-track.

So why not electrify from Princes Risborough and Calvert, where the route joins the East West Railway?

The electrification in Aylesbury station could also be used to top-up trains going to London via Amersham.

I would use 25 KVAC overhead electrification, using lightweight gantries like these, which use laminated wood for the overhead structure.

There is also a video.

Electrification doesn’t have to be ugly and out-of-character with the surroundings.

London Marylebone And Milton Keynes Via High Wycombe, Aylesbury and Aylesbury Vale Parkway

The three sections of the route are as follows.

  • London Marylebone and High Wycombe- 28.14 miles – Not Electrified
  • High Wycombe and Aylesbury – 15.35 miles – Not Electrified
  • Aylesbury and Milton Keynes – 16.50 miles – Partially Electrified

Note.

  1. The total distance is sixty miles
  2. There is some electrification to charge the trains between Bletchley and Milton Keynes.

A battery electric train, with the range of a Hitachi Regional Battery Train should be able to work this route, if they can work London Marylebone and Aylesbury, with charging at Aylesbury.

Milton Keynes Central is a fully-electrified station.

The picture shows Platform 2A, which is South-facing electrified, five-car platform, which could be used by the Chiltern service.

Train Specification

Consider.

  • Chiltern Railway’s workhorse is a Class 168 train, which is a diesel multiple unit of up to four cars, with a 100 mph operating speed.
  • The longest leg without electrification could be London Marylebone and Aylesbury via High Wycombe, which is 43.5 miles.
  • Hitachi’s Regional Battery Train has a range of fifty-six miles.
  • As there is a need to work with London Underground electrification, a dual-voltage train will be needed.

So a battery electric train with this specification would probably be ideal.

  • Four cars
  • Ability to work with both 750 VDC third-rail and 25 KVAC overhead electrification.
  • 100 mph operating speed.
  • Battery range of perhaps 55 miles.

Could the specification fit a battery-equipped Class 385 train, which will probably be built for Scotland?

Conclusion

I am convinced that battery electric trains can run between London Marylebone and Aylesbury, Aylesbury Vale Parkway and Milton Keynes stations.

The following would be needed.

  • A battery electric range of perhaps fifty-five miles.
  • Some form of charging at Marylebone and Aylesbury stations.

I would electrify, the single-track route between Princes Risborough and Aylesbury Vale Parkway.

Generating Clean Energy From The Coal Mines

The title of this post, is the same as that of this article on The Engineer.

This is the introductory paragraph.

With a number of the UK’s abandoned coal mines being repurposed for green energy projects, Jon Excell asks whether the legacy of Britain’s polluting industrial past could hold the key to its low carbon future?

A few points from this must-read article.

  • We spend £2.4 billion every year dealing with the water in abandoned mines.
  • The huge volumes of mine water – heated by geological processes to temperatures as high as 40˚C – could actually help power the UK’s shift to a zero-carbon economy.
  • The Coal Authority now has around thirty different projects.
  • there is an estimated 2.2 million GWh of annually renewing zero carbon geothermal energy held within the mines.
  • Heat can be extracted using boreholes, heat pumps and heat exchangers.
  • The mines can be used to store energy as waste heat.
  • I particularly liked the use of a mine shaft as a thermal flask, which is being developed at Shawfair in Scotland.

The article then talks about Gravitricity.

This is an extract.

According to Gravitricity project development manager Chris Yendell, the potential for the technology is huge.

Research carried out for the company by KPMG identified 60,000 vertical shafts of 200m or greater in Germany alone. Indeed, many of these shafts as deep as 1000m. Meanwhile, following discussions with the Coal Authority, the team believes that in the UK there are at least 100 potentially viable deep vertical mineshafts. “Based on that you could look at a future portfolio in the UK of 2.4GWh of capacity, based on a 10MW peak system with a capacity of 24MWh” said Yendell.

The article finishes on an optimistic note, by outlining how in the former mining areas, there is lots of expertise to maintain and run these new green energy systems, that will replace coal’s black hole.

Conclusion

Coal could be the future! But not as we know it!
