Fortescue Unveils World-First Electric Train Using Gravity To Recharge

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

These two paragraphs summarise the project.

Fortescue has announced the development of an electric train that recharges itself using gravity, as the Australian resources giant finalises its acquisition of UK-based Williams Advanced Engineering.

Fortescue is dedicating $50 million, in partnership with Williams Advanced Engineering (WAE), for research and development on the Infinity Train, which fully recharges its battery using gravitational energy when it descends.

Note.

  1. Most of Australia’s iron ore is mined in the Pilbara region of Western Australia.
  2. There are at least four railways in Pilbara leading to the coast.
  3. As the mines are higher than the coast, the heavily loaded trains will be going downhill, whereas the empties will be going uphill.
  4. There would certainly appear to be scope for charging going to the coast and coming back on a full battery with the empties.
  5. 94 % of Australia’s iron ore exports are transported by train from Pilbara to the coast.

There are hundreds of locomotives used for transportation of Iron ore from Pilbara to the coast.

Will Williams Convert Existing Locomotives?

I suspect they will as this is route that Wabtec is taking with their FLXdrive locomotives.

Will Williams Convert Locomotives For Other Pilbara Companies?

I suspect what Andrew Twiggy Forest wants he gets.

Could Williams Convert Other Diesel Electric Locomotives

I suspect they could and I wouldn’t rule out seeing a battery-electric Class 66 locomotive.

I laid out my thoughts in Could Class 66 Locomotives Be Converted Into Battery-Electric Locomotives?.

‘Game-Changing’ Drones Helping Ukraine In Battle For The Skies

The title of this post, is the same as that of this article in The Times.

This is the introductory paragraph.

The Ukrainian military has been using “Punisher” stealth drones that can target fuel storage, ammunition supplies and electronic warfare stations up to 30 miles behind enemy lines.

Some other points from the article.

  • They are a Ukrainian-built drone with a 7.5 foot wingspan an electric propulsion.
  • They are from a company called UA-Dynamics.
  • They have completed sixty successful mission.
  • They can fly for hours at 1,300ft

This paragraph describes a mission.

He said the drone, which can carry 3kg of explosives, needs the co-ordinates of its target and then carries out its mission automatically. Onboard cameras record the impact of the blast to check the accuracy of the mission.

It can also work in combination with a reconnaissance drone.

Could this be the reason the Russians have held back the convoy?

It may not be a big enough warhead to knock out a tank, but it would do a lot of damage to a supply truck or a tanker full of diesel.

There is also this paragraph, which describes a dog-fight between Russian and Ukranian fighters.

The Ukrainian military said today that a “fierce air battle” took place overnight in the Kyiv region between a pair of MiG-29 fighters and a pair of Russian Su-35s. Both Russian jets were destroyed and one MiG-29 survived.

Note.

  1. The Mig-29 first flew in 1977.
  2. Mig-29s are a very common fighter aircraft.
  3. Ukraine inherited hundreds of Mig-29s after the collapse of the Soviet Union.
  4. The USAF has a few Mig-29s

The Su-35 first flew in 1988.

In addition to the Russians, they are flown by China and Egypt.

This is a paragraph from the Wikipedia entry for the Mig-29.

On 29 May 2020, Ukrainian MiG-29s took part in the Bomber Task Force in Europe with American B-1B bombers for the first time in the Black Sea region. In September 2020, B-52 bombers from the 5th Bomb Wing conducted vital integration training with Ukrainian MiG-29s and Su-27s inside Ukraine’s airspace.

Have the Ukrainian pilots been doing some combat training?

Scotland’s Energy Storage

I have been using the web sites of Drax Group, SSE Renewables and ILI Group, and this page from Strathclyde University to look at various hydro-electric schemes to store energy using the tried-and-tested method of pumped hydro.

I have analysed these schemes.

Affric/Beauly

The scheme is now owned by SSE Renewables and has a page on their web site, which introduces the scheme like this.

Situated about 16 kilometres to the west of Inverness, Beauly is the gateway to the Affric/Beauly hydro electric scheme.

Currently, it generates a maximum power of 100.3 MW.

My analysis in Repurposing The Affric/Beauly Hydro-Electric Scheme, showed the following.

  • Research from Strathclyde University, says that the Affric/Beauly scheme could support 78 GWh of pumped storage in one scheme at Fasnakyle.
  • Adding pumped storage facilities to the Affric/Beauly hydro-electric scheme, with a capacity of upwards of a conservative 50 GWh, should be possible.

Generating capacity and system operation could be improved by replacing some or all of the 1950s and 1960s turbines with modern units and using modern control systems.

The Affric/Beauly hydro-electric scheme could be augmented by upwards of 50 GWh of storage.

Balliemeanoch

This new scheme is being developed by the ILI Group.

From what is published in the press. it appears to be a giant 1.5 GW/45 GWh project.

In Thoughts On The Balliemeanoch Pumped-Hydro Scheme, I analyse the plan.

The Balliemeanoch hydro-electric scheme could add 45 GWh of storage.

Balmacaan

This new scheme is being developed by SSE Renewables.

My searches in A Possible Balmacaan Pumped Storage System, showed the following.

It has a 600 MW generating capacity and I suspect would have about 15-20 GWh of storage.

The Balmacaan hydro-electric scheme could conservatively add upwards of 15 GWh of storage.

Breadalbane

The scheme is now owned by SSE Renewables and has a page on their web site, which introduces the scheme like this.

The Breadalbane scheme is set in the mountainous region around Loch Lyon, Loch Tay and Loch Earn in Perthshire.

Currently, it generates a maximum power of 168.4 MW.

My analysis in Repurposing The Breadalbane Hydro-Electric Scheme, showed the following.

  • Research from Strathclyde University, says that the Breadalbane scheme could support 12 GWh of pumped storage in one scheme at Ben Lawers.
  • I believe a similar scheme could be built South of Loch Tay to add a similar amount of pumped storage capacity.

As with the Beauly/Affric scheme, generating capacity and system operation could be improved by replacing some or all of the 1950s and 1960s turbines with modern units and using modern control systems.

The Breadalbane hydro-electric scheme could be augmented by upwards of 12 GWh of storage.

Coire Glass

This new scheme is being developed by SSE Renewables and the project has its own web site, which introduces the scheme like this.

Coire Glas is a hydro pumped storage scheme with a potential capacity of up to 1500MW. Coire Glas is an excellent pumped storage site with a large lower reservoir (Loch Lochy) and a significant elevation of more than 500m between the lower and the new upper reservoir site over a relatively short distance.

It is planned to generate a maximum power of up to 1.5 GW for twenty hours, which indicates an energy storage capacity of 30 GWh.

In SSE Renewables Launches 1.5GW Coire Glas Construction Tender, I talk about the current status of the project.

The Coire Glas hydro-electric scheme could add 30 GWh of storage.

Conon

The scheme is now owned by SSE Renewables and has a page on their web site, which introduces the scheme like this.

The Conon scheme lies within the northwest Highlands, broadly between Inverness and Ullapool. Electricity generation started here when the Ross-shire Electricity Supply Company built the small Falls of Conon hydro electric power station in the 1920s.

Currently, it generates a maximum power of 107.2 MW.

My analysis in Repurposing The Conon Hydro-Electric Scheme, showed the following.

  • Research from Strathclyde University, says that the Conon scheme could support up to 131 GWh of pumped storage.
  • Adding pumped storage facilities to the Conon hydro-electric scheme, with a capacity of upwards of a conservative 30-40 GWh, should be possible.

As with other schemes, generating capacity and system operation could be improved by replacing some or all of the 1950s turbines with modern units and using modern control systems.

The Conon hydro-electric scheme could be augmented by upwards of 30 GWh of storage.

Corrievarkie

This new scheme is being developed by the ILI Group.

From the planning application it appears to be a 600 MW/14.5 GWh project.

In Corrievarkie Pumped Storage Hydro Project, I analyse the plan.

The Corrievarkie hydro-electric scheme could add 14.5 GWh of storage.

Cruachan

Cruachan is a pumped-storage power station, that is owned by Drax, which have a comprehensive web site for the power station.

  • It has an output of 440 MW.
  • It has an energy storage capacity of 7.1 GWh
  • It can can reach full generating capacity in less than 30 seconds.

In Drax’s Plans For Cruachan, I analyse Drax’s plans, which they call Cruachan 2.

  • It will be a 600 MW power station.
  • It will be to the East of the current power station.
  • More than a million tonnes of rock would be excavated to build the power station.

The existing upper reservoir, which can hold 2.4 billion gallons of water, has the capacity to serve both power stations.

These was my conclusions.

It looks like very good engineering to me.

  • There is a good chance, that on most nights, the reservoir will be filled using wind energy
  • The maximum output of the Cruachan power station has been more than tripled from 323 to 1010 MW.
  • There has been no increase in the size of the Cruachan reservoir.

Scotland will now have a GW-sized hydro-electric power station.

It will not be very much smaller than Sizewell B nuclear station.

Foyers

The scheme is now owned by SSE Renewables and has a page on their web site, which introduces the scheme like this.

The current Foyers Power Station operates quite differently to conventional hydro electric power stations. Foyers hydro scheme consists of one pumped hydro power station and one hydro power station and one major dam..

Currently, it generates a maximum power of 305 MW.

My research and analysis in The Development Of The Foyers Pumped Storage Scheme, showed the following.

  • Foyers is a modern pumped-hydro scheme with a capacity of 10 GWh.
  • The updating of the original 1896 hydro-power station to a modern pumped-storage system in 1974 is a superb example of hydro-power engineering.

The development of Foyers power station is an example, that shows what can be done in other hydro-electric schemes around Scotland and the rest of the world.

Galloway

Galloway is a hydroelectric scheme, that is owned by Drax, which have a comprehensive web site for their two hydroelectric schemes in Scotland; Galloway and Lanark.

  • Galloway has a total output of 109 MW.
  • It has six power stations at Drumjohn, Kendoon, Carsfad, Earlstoun, Glenlee and Tongland.
  • There is no energy storage
  • It is what is known as a run-of-the-river scheme.

The scheme opened in the 1930s.

Glendoe

The scheme is now owned by SSE Renewables and has a page on their web site, which introduces the scheme like this.

In 2009, the first major hydro electric power station to be built in Scotland for almost 30 years, Glendoe on the eastern shore of Loch Ness, began generating electricity.

Currently, it generates a maximum power of 106.5 MW.

My analysis in Glendoe Hydro Power Station, led me to conclude, that engineers will look at this scheme built in the early years of this century to convert it to a pumped storage facility. It might even have been designed for conversion to a pumped storage station, as it was built after the successful conversion of Foyers power station. Comparing the size of the upper lake to Foyers and other schemes, I would estimate it could easily provide in excess of 15 GWh of storage.

The Glendoe hydro-electric scheme could be augmented by upwards of 15 GWh of storage.

Glenmuckloch

This is a small scheme promoted by Buccleuch, that generates 4 MW and stores 1.6 GWh in a disused opencast coal mine.

My analysis in The Glenmuckloch Pumped Storage Scheme, led me to this conclusion.

This project appears to have stalled, but I do like the idea of using a disused mine to store energy and the engineering behind the project.

I will ignore it in my conclusions of this post.

Great Glen

The scheme is now owned by SSE Renewables and has a page on their web site, which introduces the scheme like this.

The Great Glen runs for more than 100 kilometres from Inverness in the northeast, to Fort William in the southwest, following a geological fault line that divides north and south Scotland.

Currently, it generates a maximum power of 112.7 MW.

My analysis in Repurposing The Great Glen Hydro-Electric Scheme, showed the following.

  • Research from Strathclyde University, says that the Great Glen scheme could support up to 90 GWh of pumped storage.
  • Adding pumped storage facilities to the Great Glen hydro-electric scheme, with a capacity of upwards of a conservative 30 GWh, should be possible.

As with other schemes, generating capacity and system operation could be improved by replacing some or all of the 1950s and 1960s turbines with modern units and using modern control systems.

The Great Glen hydro-electric scheme could be augmented by upwards of 30 GWh of storage.

Lanark

Lanark is a hydroelectric scheme, that is owned by Drax, which have a comprehensive web site for their two hydroelectric schemes in Scotland; Galloway and Lanark.

  • Lanark has a total output of 17 MW.
  • It has two power stations at Bonnington and Stonebyres.
  • There is no energy storage
  • It is what is known as a run-of-the-river scheme.

The scheme opened in the 1920s.

Red John

This new scheme is being developed by ILI Group and the project has its own web site, which introduces the scheme like this.

Between 2007 and 2015, the total installed capacity of renewables electricity in Scotland has more than doubled. Due to its intermittent nature, the rise in renewable generation has resulted in increased demand for flexible capacity to help meet energy balancing requirements for the national grid system.

Pumped storage hydro is considered by the Directors to be the most developed and largest capacity form of grid energy storage that currently exists. This can help reduce renewable energy curtailment and therefore promote grid stability.

The web site says this about the project.

  • The scheme has an output of 450 MW.
  • The storage capacity is 2.8 GWh.
  • The scheme has planning consent.
  • The project is budgeted to cost £550 million.
  • The construction program indicates that the scheme will be completed by the end of 2025.

It also has very detailed maps.

I wrote about the project in Red John Pumped Storage Hydro Project, where I came to these conclusions.

  • This scheme has the output of a large gas-fired power station for just over six hours.
  • The finances must add up, as no-one would back a scheme like this if they didn’t get an adequate return on their money.

It may only be a small scheme, that is a quarter of the size of the existing nearby Foyers pumped-storage scheme, but as it is shovel-ready, we should start digging.

The Red John hydro-electric scheme would add 2.8 GWh of storage.

Shin

The scheme is now owned by SSE Renewables and has a page on their web site, which introduces the scheme like this.

Shin is Scotland’s most northerly hydro electric scheme. It utilises water from a 650 square kilometre catchment area in Sutherland, including Loch Shin, and water from the River Cassley and River Brora.

Currently, it generates a maximum power of 32.1 MW.

My analysis in Shin Hydro Power Scheme, showed the following.

  • I would be very surprised if any pumped storage were to be added to this scheme.
  • This 1950s scheme has been partially updated.

Perhaps some more updating would be worthwhile.

Sloy/Awe

The scheme is now owned by SSE Renewables and has a page on their web site, which introduces the scheme like this.

With the exception of Cruachan Power Station which was commissioned in 1965, major work on the Sloy/Awe scheme was completed by 1963, the year the Beatles had their first No 1 hit with From Me To You – and a world away from the immediate post-war austerity being experienced when Sloy Power Station was commissioned just 14 years earlier.

Currently, it generates a maximum power of 261.9 MW.

My analysis in Repurposing The Sloy/Awe Hydro-Electric Scheme, showed the following.

  • Research from Strathclyde University, says that the Sloy/Awe scheme could support up to 68 GWh of pumped storage.
  • Adding pumped storage facilities to the Sloy/Awe hydro-electric scheme, with a capacity of upwards of a conservative 40 GWh, should be possible.

As with other schemes, generating capacity and system operation could be improved by replacing some or all of the 1930s and 1950s turbines with modern units and using modern control systems.

The Sloy/Awe hydro-electric scheme could be augmented by upwards of 40 GWh of storage.

Tummel Valley

The scheme is now owned by SSE Renewables and has a page on their web site, which introduces the scheme like this.

The Tummel scheme stretches from Dalwhinnie, famous for its whisky distillery, in the north, to the remote Rannoch Station in the west, and the highly-popular tourist town of Pitlochry in the east.

Currently, it generates a maximum power of 309.2 MW.

My analysis in Repurposing The Tummel Hydro-Electric Scheme, showed the following.

  • Research from Strathclyde University, says that the Tummel Valley scheme could support up to 135 GWh of pumped storage.
  • Adding pumped storage facilities to the Tummel Valley hydro-electric scheme, with a capacity of upwards of a conservative 40-60 GWh, should be possible.

As with other schemes, generating capacity and system operation could be improved by replacing some or all of the 1930s and 1950s turbines with modern units and using modern control systems.

The Tummel Valley hydro-electric scheme could be augmented by upwards of 40 GWh of storage.

A Simple Summary

These are deliberately conservative figures from my analysis.

  • Affric/Beauly – 50 GWh
  • Balliemeanoch – 45 GWh
  • Balmacaan – 15 GWh
  • Breadalbane – 12 GWh
  • Coire Glas – 30 GWh
  • Conon – 30 GWh
  • Corrievarkie – 14.5 GWh
  • Glendoe – 15 GWh
  • Great Glen – 30 GWh
  • Red John – 2.8 GWh
  • Sloy/Awe – 40 GWh
  • Tummel Valley – 40 GWh

Note.

  1. With new storage like Balliemeanoch, Balmacaan, Coire Glas, Corrievarkie and Red John, I am using published figures where they are available.
  2. With figures from existing schemes,I am being deliberately very conservative.

That is a total of 324.3 GWh with 107.3 GWh down to new storage

Strathclyde University’s Prediction

This page on the Strathclyde University web site, gives these figures for the possible amounts of pumped-storage that can be added to existing schemes.

  • Errochty – 16
  • Glasgarnock – 23
  • Luichart – 38
  • Clunie – 40
  • Fannich – 70
  • Rannoch – 41
  • Fasnakyle – 78
  • Tummel – 38
  • Ben Lawers – 12
  • Nant – 48
  • Invermoriston – 22
  • Invergarry – 41
  • Quoich – 27
  • Sloy – 20

That is a total of 514 GWh or 621.3 GWh if you include new storage.

Conclusion

Scotland and the UK, has been left a superb legacy for the future by the pioneering work of Scottish engineers and the North of Scotland Hydroelectric Board.

Most of these assets are now in the hands of two groups; Scottish and Southern Energy (SSE) and Drax Group.

Having seen several of the schemes detailed in this post, in the last few weeks, on Michael Portillo’s; Great Coastal Railway Journeys, it does seem that both groups are looking after their assets.

SSE and Drax also seem to be doing their best to publicise the success of one of the UK’s high-value, but low-profile engineering assets.

I believe that we should do a survey that would identify the following.

  • What needs to be done to allow each aqueduct, dam, power station and tunnel to continue to function until a given date in the future.
  • Which of the individual schemes can be updated to larger schemes or pumped storage systems.

We would then be able to device a long term plan to create a world-class hydro-electric power scheme for Scotland.

Scotland should be able to provide upwards of 400 GWh of pumped-storage.

This article on Current News is entitled Up To 24GW Of Long Duration Storage Needed For 2035 Net Zero Electricity System – Aurora.

These are the first three paragraphs.

Deploying large quantities of long duration electricity storage (LDES) could reduce system costs and reliance on gas, but greater policy support is needed to enable this, Aurora Energy Research has found.

In a new report, Aurora detailed how up to 24GW of LDES – defined as that with a duration of four hours or above – could be needed to effectively manage the intermittency of renewable generation in line with goals of operating a net zero electricity system by 2035. This is equivalent to eight times the current installed capacity.

Additionally, introducing large quantities of LDES in the UK could reduce system costs by £1.13 billion a year in 2035, cutting household bills by £26 – a hot topic with energy bills on the rise as a result of high wholesale power prices.

The report also says that long duration storage could cut carbon emissions by ten million tonnes of carbon dioxide per year.

It appears to me, Scotland can provide more than enough energy storage for the UK and the Island of Ireland, even if the seas around the British Isles were almost completed covered by wind turbines.

In addition, to the works in Scotland to update the various hydroelectric schemes, there would need to be more interconnectors around the UK and probably to close countries like Belgium, Denmark, France, Germany, the Netherlands and Norway.

There could even be an interconnector between Iceland and Scotland, so Iceland’s abundance of zero-carbon electricity could be exported to Europe.

Is The Truth Getting Through To The Man Or Woman On The Moscow Tram?

I ask this question, as it appears that Russian TV is parroting, the Kremlin’s lies.

In the late 1960s and early 1970s, I used to work for ICI.

A couple of times, I came across fellow engineers, who had worked on the Polyspinners project.

In this Wikipedia entry for September 1964, this is said about Polyspinners.

Edward du Cann of the British Board of Trade announced the signing of the largest trade deal in the history of British relations with the Soviet Union, with the Soviet purchasing agency Techmashimport and the British conglomerate Polyspinners, Ltd. agreeing for the supply of British textile machinery to a polyester fiber plant being constructed in Krasnoyarsk in Siberia. In all, the United Kingdom agreed to advanced $67 million of credit over a 15-year period.

It was a large project and ICI did well out of it.

My colleagues at ICI generally spoke well of the project and friends they had made in Russia and in those pre-mobile phone and internet days, they regularly sent each other cards and letters.

That was nearly sixty years ago, but human beings generally want to be friends with each other, so how many links are there between people living in Western Europe, North America, Australia and other countries and those living in Russia, which started as family, business or historic links or even casual meetings on say a holiday in the Mediterranean?

I should say that two of my best British friends in the UK, I met on holiday in St. Kitts and Moscow.

There must be millions of these links and they will surely allow the truth to get through to the man or woman on the Moscow tram.

Final Tunnelling Gets Underway On Bank Station Blockade

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

This is the introductory paragraph.

Four weeks into the closure of Bank Station for its capacity upgrade, main contractor Dragados is making good progress on all key activities, including final tunnelling works.

This has been traditional tunneling, that would have been familiar to those like the Victorians, where a lot of the digging has been done by hand, with the addition of smaller diggers and power tools.

The project seems to be on schedule for a mid-May opening.
