The Concept Of Remote Island Wind
This document from the Department of Business, Industry and Industrial Strategy lists all the Contracts for Difference Allocation Round 4 results for the supply of zero-carbon electricity that were announced yesterday.
The contracts have also introduced a concept that is new to me, called Remote Island Wind. All have got the same strike price of £46.39 per MWh.
Two of the projects on Orkney are community projects of around 30 MW, run by local trusts. This is surely, a model that will work in many places.
There is more on Orkney’s Community Wind Farm Project on this page of the Orkney Islands Council web site.
It could even have an electrolyser to provide hydrogen for zero-carbon fuel, when there is more electricity than is needed. Companies like ITM Power and others already build filling stations with an electrolyser, that can be powered by wind-generated electricity.
The other Remote Island Wind projects are larger with two wind farms of over 200 MW.
It does look to me, that the Department of BEIS is nudging wind farm developers in remote places to a model, that all stakeholders will embrace.
The Viking Wind Farm
I wrote about this wind farm in Shetland’s Viking Wind Farm.
There are more details in this press release from SSE enewables, which is entitled CfD Contract Secured For Viking Energy Wind Farm.
These introductory paragraphs, give a good explanation of the finances of this farm.
SSE Renewables has been successful in the UK’s fourth Contract for Difference (CfD) Allocation Round, announced today, and has secured a low-carbon power contract for 220MW for its wholly-owned Viking Energy Wind Farm (Viking) project, currently being constructed in Shetland.
Viking’s success in securing a contract follows a competitive auction process in Allocation Round 4 (AR4) where it competed within Pot 2 of the allocation round set aside for ‘less established’ technologies including Remote Island Wind.
The 443MW Viking project, which SSE Renewables is currently building in the Shetland Islands, has secured a CfD for 220MW (50% of its total capacity) at a strike price of £46.39/MWh for the 2026/27 delivery year.
The successful project will receive its guaranteed strike price, set on 2012 prices but annually indexed for CPI inflation, for the contracted low carbon electricity it will generate for a 15-year period. Securing a CfD for Viking stabilises the revenue from the project whilst also delivering price security for bill payers.
It’s very professional and open to explain the capacity, the contract and the finances in detail.
The press release also has this paragraph, which details progress.
Viking is progressing through construction with over 50 per cent of turbine foundation bases poured. When complete in 2024, Viking Energy Wind Farm will be the UK’s most productive onshore wind farm in terms of annual electricity output, with the project also contributing to Shetland’s security of supply by underpinning the HVDC transmission link that will connect the islands to the mainland for the first time.
SSE also released this press release, which is entitled Major Milestone Reached As First Subsea Cable Installation Begins On Shetland HVDC Link, where this is the first paragraph.
The first phase of cable laying as part of the SSEN Transmission Shetland High-Voltage Direct Current (HVDC) Link began this week off the coast of Caithness, marking a major milestone in the £660M project.
SSE seem to be advancing on all fronts on the two projects!
The Stornoway Wind Farm
This press release from EDF Renewables is entitled EDF Renewables UK Welcomes Contract for Difference Success, where these are the first two paragraphs.
Two EDF Renewables UK projects bid into the Contract for Difference (CfD) auction round held by the UK Government’s BEIS department have been successful.
The projects are the Stornoway wind farm on the Isle of Lewis and Stranoch wind farm in Dumfries and Galloway. Together these onshore wind farms will provide 300 MW of low carbon electricity which is an important contribution to reaching net zero.
The press release also gives this information about the contract and completion of the Stornoway wind farm.
Stornoway Wind Farm on the Isle of Lewis is a joint venture with Wood. The project has won a CfD for 200 MW capacity, the strike price was £46.39, the target commissioning date is 31 March 2027.
This page on the Lewis Wind Power web site, gives these details of the Stornoway Wind Farm.
The Stornoway Wind Farm would be located to the west of the town of Stornoway in an area close to the three existing wind farm sites.
The project has planning consent for up to 36 turbines and is sited on land owned by the Stornoway Trust, a publicly elected body which manages the Stornoway Trust Estate on behalf of the local community.
The local community stands to benefit as follows:
- Community benefit payments currently estimated at £900,000 per annum, which would go to an independent trust to distribute to local projects and organisations
- Annual rental payments to local crofters and the Stornoway Trust – which we estimate could total more than £1.3m, depending on the CfD Strike Price secured and the wind farm’s energy output
- Stornoway Wind Farm is the largest of the three consented wind farm projects with a grid connection in place and is therefore key to the needs case for a new grid connection with the mainland. Indeed, the UK energy regulator Ofgem has stated that it will support the delivery of a new 450MW cable if the Stornoway and Uisenis projects are successful in this year’s Contract for Difference allocation round.
Note the last point, where only the Stornoway wind farm was successful.
The Uisenis Wind Farm
This press release from EDF Energy is entitled Lewis Wind Power Buys Uisenis Wind Farm, gives these details of the sale.
Lewis Wind Power (LWP), a joint venture between Amec Foster Wheeler and EDF Energy Renewables has bought the Uisenis Wind Farm project on the Isle of Lewis. The wind farm has planning consent for the development of 45 turbines with a maximum capacity of 162 MW. This would be enough to power 124,000 homes and would be the biggest renewable energy development on the Western Isles.
LWP owns the Stornoway Wind Farm project located around 20km to the north of Uisenis which has planning consent to develop 36 turbines to a maximum capacity of 180 MW – enough to power 135,000 homes.
This would bring Stornoway and Uisenis wind farms under the similar ownership structures.
This is a significant paragraph in the press release.
On behalf of Eishken Limited, the owner of the site where the Uisenis Wind Farm will be located, Nick Oppenheim said: “I am delighted that LWP are taking forward the wind farm. The resources available on the Eishken estate, and the Western Isles in general, means that it is an excellent location for renewable energy projects and, as such, the company is also developing a 300MW pumped storage hydro project immediately adjacent to the Uisenis wind farm. With such potential for renewables and the positive effect they will have on the local community, economy, and the UK as a whole I am are looking forward to positive news on both support for remote island projects and the interconnector.”
Note the mention of pumped storage.
This article on the BBC is entitled Pumped Storage Hydro Scheme Planned For Lewis, where this paragraph introduces the scheme.
A pumped storage hydro scheme using sea water rather than the usual method of drawing on freshwater from inland lochs has been proposed for Lewis.
The only other information is that it will provide 300 MW of power, but nothing is said about the storage capacity.
It looks like Lewis will have a world-class power system.
Mossy Hill And Beaw Field Wind Farms
Mossy Hill near Lerwick and Beaw Field in Yell are two Shetland wind farms being developed by Peel L & P.
This press release from Peel L & P is entitled Government Support For Two Shetland Wind Farms, where these are the first two paragraphs.
Plans for two onshore wind farms on the Shetland Islands which would help meet Scotland’s targets for renewable energy production are a step closer to being delivered after receiving long-term Government support.
Clean energy specialists Peel NRE has been successful in two bids in the Department for Business, Energy and Industrial Strategy’s (BEIS) Contracts for Difference (CfD) scheme; one for its Mossy Hill wind farm near Lerwick and the other for Beaw Field wind farm in Yell.
It looks like the two wind farms will power 130,000 houses and are planned to be operational in 2027.
Conclusion
I must admit that I like the concept. Especially, when like some of the schemes, it is linked to community involvement and improvement.
Only time will tell, if the concept of Remote Island Wind works well.
Hexicon Wins UK’s First Ever CfD Auction For Floating Offshore Wind
The title of this post, is the same as that of this press release from Hexicon.
This is the first paragraph.
Today (7th of July) the UK Government confirmed that Hexicon AB’s TwinHub project in the Celtic Sea was successful in the latest Contracts for Difference (CfD) Allocation Round (AR4). It has been awarded a CfD for its 32MW floating wind project at a strike price of £87.30/MWh (2012 real prices) taking the project a significant step closer to completion.
This image shows one of their TwinHub turbine installations being towed into place.
The TwinHub home page has a title of The First Floating Offshore Wind Project in The Celtic Sea.
This is the description on the page.
The TwinHub offshore wind demonstration project intends to prove how Hexicon’s innovative design with two turbines on one floating foundation can further reduce the Levelized Cost of Energy (also referred to as LCoE) before large scale commercialisation. The TwinHub project is a stepping stone to help kick-start floating wind in the Celtic Sea, an area identified as a hotspot for floating wind by the UK Government. It will pave the path for larger and larger projects to help support The Crown Estates’ ambitious target of 4GW of floating wind in the Celtic Sea.
Scroll the page down and there is a short video of a pair of wind turbines in operation.
- It appears that when there is no wind, it automatically goes into a safe parked mode.
- As the wind rises, one turbine starts up.
- The second turbine starts up and the float turns so they face the wind.
It appears to be a classic example of disruptive innovation.
I did the calculations for floating and reusable oil and gas platforms in the 1970s, that were designed by two Cambridge University professors, which would have been launched horizontally and upturned when in position. This experience leads me to believe that the Swedish designers of this type of platform have been able to verify that this is a workable design.
This document from the Department of Business, Industry and Industrial Strategy indicates that the demonstration is for 32 MW.
Does that indicate, that this installation is twin 16 MW wind turbines?
16 MW seems to be the size of the largest wind turbines in the world.
There is a lot to like about this Swedish design.
- As the video shows, it appears to balance itself with the wind.
- I suspect from the calculations I did in Cambridge, that the twin design with its higher weight is more stable than a floating single turbine design.
- The float and its two turbines can be assembled alongside a dock with a large stable onshore dockside crane.
- Servicing would also be done in a dock.
- Working onshore is much safer and easier, than working offshore.
- The twin design allows more power to be generated in a given area of sea.
This is a brilliant concept and it will give Putin, the Sheikhs and the other oil dictators, the most terrible of nightmares.
The initial site chosen for this design in the UK, will be in the sea at Hayle in Cornwall.
This map shows the location.
Hayle is in the North-East corner of the map, by the sandy beach.
A 32 MW turbine could probably provide enough electricity for 15,000 houses.
Air Products Partners Up On Hydrogen Production In The UK
The title of this post, is the same as that of this article on Upstream.
These three paragraphs explain the project.
Air Products has joined with power generator VPI to push forward a hydrogen hub on the south bank of the Humber Estuary in the UK, primarily meant to decarbonise VPI’s power production in Immingham.
The companies said they will develop an 800-megawatt production facility called the Humber Hydrogen Hub (H3) that would include carbon capture and storage and aim to capture up to 2 million tonnes per annum of carbon dioxide.
Hydrogen produced at the facility will first substitute fuel for VPI’s existing third gas turbine power train.
Note.
- VPI is a UK-based power company, providing energy to the National Grid.
- Immingham Power station is currently a 730 MW gas-fired power station, which is being expanded to 1240 MW.
- It looks like that expansion will use hydrogen.
It is all part of HumberZero.
Extending The Elizabeth Line – Linking To The Oxted Line
I believe that everybody in the South East of England needs the best access possible to the Elizabeth Line, by train from where they live.
- The Elizabeth Line serves the important places like Brick Lane, Canary Wharf, the City of London, Heathrow Airport, Liverpool Street station, the Olympic Park, Oxford Street and Paddington station directly.
- Because of its connection to Thameslink, the Elizabeth Line also serves important places like Bedford, Brighton, Cambridge, Gatwick Airport, Luton Airport and Tate Modern with a single change at Farringdon station.
- Using the Elizabeth Line, Thameslink and perhaps a bus, it is possible to get to most important places in Central London.
- The more passengers that use the Elizabeth Line and Thameslink, the more London’s businesses will thrive creating employment and tax revenues.
- It should also be remembered, that using a train to visit central London, probably cuts your carbon footprint.
- The Elizabeth Line also cost a fortune, so perhaps by using it, you will be getting some of your portion of what it cost you back.
This post is the first of several, where I discuss how to bring more passengers into the Elizabeth Line network.
The Oxted Line
The Oxted Line is a line with two branches; East Grinstead and Uckfield, which runs South from East Croydon station.
- The branch to East Grinstead is electrified, but the branch to Uckfield is not and is still run by diesel trains.
- Plans exist to run battery-electric trains on the Uckfield branch, but they always seem to be awaited,
- Network Rail are now saying that they will electrify the Uckfield branch with third-rail.
- All platforms on both branches can take ten-car trains, if not twelve.
- A reasonable amount of money has been spent on the Uckfield branch to improve it.
- Services on both branches are one train per hour (tph).
- London terminals of trains are London Bridge and Victoria, both of which have no easy connection to the Elizabeth Line.
The major faults of the current services are as follows.
- One tph is not enough.
- Victoria is an overcrowded terminal with no connection to the Elizabeth Line or Thameslink
- At London Bridge and East Croydon, there are tortuous step-free change to Thameslink.
- From London Bridge you can use the Northern Line to transfer to the Elizabeth Line, but it wouldn’t be the best route when taking a heavy case to Heathrow.
- From Victoria, you can use the Circle and District lines to the Elizabeth Line at Paddington.
The Oxted Line service needs to be improved.
I would do the following.
Move Uckfield Branch Services To Thameslink
This would mean that Uckfield services would call at East Croydon, London Bridge, Blackfriars, City Thameslink, Farringdon, St. Pancras and then terminate somewhere to the North.
- There would be a step-free change to the Elizabeth Line at Farringdon.
- East Croydon and London Bridge are still served.
- There are connections to the Circle, District, Hammersmith & City, Jubilee, Metropolitan, Northern, Piccadilly and Victoria Lines of the Underground.
- There will be no need for a terminal platform at London Bridge.
I believe that this gives much better connectivity.
Electrify To Uckfield
This is a long-debated question.
But as Thameslink trains are Class 700 trains, which are dual voltage, I’d electrify the Uckfield branch with 25 KVAC overhead electrification between Hurst Green and Uckfield.
Lightweight catenary could be used to reduce visual intrusion.
Note.
- The curved beam at the top of this overhead electrification gantry is laminated wood.
- Power changeover would take place at Hurst Green station.
Hopefully, the electric trains would offset any anger at overhead wires.
Run Two tph To Uckfield
I am fairly certain that when Network Rail lengthened the platforms on the Uckfield branch, that they arranged the track and signalling, so that two tph could use the branch.
Run An Hourly Shuttle Between Oxted And East Grinstead
This service would be as follows.
- It would terminate in the bay platform at Oxted station.
- This would give 2 tph on this route.
The existing hourly service between East Grinstead and Victoria would continue.
Conclusion
I believe that this simple scheme could give very good benefits to all stakeholders.
Extending The Elizabeth Line – Toilets On A Service Between Heathrow And Southend Airports
The Wikipedia entry for Crossrail, has a section about an extension to Southend Airport, where this is said.
Stobart Aviation, the company that operates Southend Airport in Essex, has proposed that Crossrail should be extended beyond Shenfield along the Shenfield–Southend line to serve Southend Airport and Southend Victoria. The company has suggested that a direct Heathrow-Southend link could alleviate capacity problems at Heathrow. The extension proposal has been supported by Southend-on-Sea City Council.
I think there could be a big problem, in that I estimate the journey will take a few minutes short of two hours. Surely, this will mean toilets will need to be fitted.
Extending The Elizabeth Line – Rebuilding Shenfield Station
I have a feeling that Shenfield station will become a bottleneck on the Great Eastern Main Line.
- I feel that both passenger and freight traffic will increase through the station in the next ten years.
- I also feel that there is a possibility that the Elizabeth Line will be extended to Southend/Airport/Victoria and/or Beaulieu.
- Yesterday, I changed between a Southend and a Lizzie Line service, which meant down in one lift and up in another.
- With more and more housing likely to be built in the area, I wouldn’t be surprised to see a lot more parking.
I wouldn’t be surprised to see the station needing to be rebuilt and expanded in the next few years.
Shell To Start Building Europe’s Largest Renewable Hydrogen Plant
The title of this post, is the same as that of this press release from Shell.
This is the first paragraph.
Shell Nederland B.V. and Shell Overseas Investments B.V., subsidiaries of Shell plc, have taken the final investment decision to build Holland Hydrogen I, which will be Europe’s largest renewable hydrogen plant once operational in 2025.
Theconstruction timeline for Holland Hydrogen 1 is not a long one.
The next paragraph describes the size and hydrogen production capacity.
The 200MW electrolyser will be constructed on the Tweede Maasvlakte in the port of Rotterdam and will produce up to 60,000 kilograms of renewable hydrogen per day.
200 MW is large!
The next paragraph details the source of the power.
The renewable power for the electrolyser will come from the offshore wind farm Hollandse Kust (noord), which is partly owned by Shell.
These are my thoughts.
Refhyne
Refhyne is a joint project between Shell and ITM Power, with backing from the European Commission, that has created a 10 MW electrolyser in Cologne.
The 1300 tonnes of hydrogen produced by this plant will be integrated into refinery processes.
Refhyne seems to have been very much a prototype for Holland Hydrogen 1.
World’s Largest Green Hydrogen Project – With 100MW Electrolyser – Set To Be Built In Egypt
The sub-title is the title, of this article on Recharge.
It looks like Holland Hydrogen 1, is double the current largest plant under construction.
Shell is certainly going large!
Will ITM Power Be Working Again With Shell?
Refhyne has probably given Shell a large knowledge base about ITM Power’s electrolysers.
But Refhyne is only 10 MW and Holland Hydrogen 1 is twenty times that size.
This press release from ITM Power is entitled UK Government Award £9.3 m For Gigastack Testing.
This is the first paragraph.
ITM Power (AIM: ITM), the energy storage and clean fuel company, announces that the Company has been awarded a contract by The Department for Business, Energy and Industrial Strategy (BEIS), under its Net Zero Innovation Portfolio Low Carbon Hydrogen Supply 2 Competition, to accelerate the commercial deployment of ITM Power’s 5 MW Gigastack platform and its manufacture. The award for the Gigatest project is for £9.3m and follows initial designs developed through previous BEIS funding competitions.
Note.
- The Gigastack is 2.5 times bigger, than ITM Power’s previously largest electrolyser.
- Forty working in parallel, in much the same way that the ancient Egyptians built the pyramids, will be needed for Holland Hydrogen 1.
- ITM Power have the world’s largest electrolyser factory, with a capacity of one GW. They have plans to create a second factory.
ITM Power would probably be Shell’s low-risk choice.
My company dealt with Shell a lot in the 1970s, with respect to project management software and we felt, that if Shell liked you, they kept giving you orders.
The Hollandse Kust Noord Wind Farm
This wind farm is well described on its web site, where this is the introduction on the home page.
CrossWind, a joint-venture between Shell and Eneco, develops and will operate the Hollandse Kust Noord subsidy-free offshore wind project.
Hollandse Kust Noord is located 18.5 kilometers off the west coast of the Netherlands near the town of Egmond aan Zee.
CrossWind plans to have Hollandse Kust Noord operational in 2023 with an installed capacity of 759 MW, generating at least 3.3 TWh per year.
This Google Map shows the location of Egmond aan Zee.
Note that the red arrow points to Egmond aan Zee.
Will The Electrolyser Be Operational In 2025?
If Shell choose ITM Power to deliver the electrolysers, I don’t think Shell are being that ambitious.
I would suspect that connecting up an electrolyser is not the most complicated of construction tasks.
- Build the foundations.
- Fix the electrolyser in place.
- Connect power to one end.
- Connect gas pipes to the other.
- Switch on and test.
Note.
- If ITM Power deliver electrolysers that work, then the installation is the sort of task performed on chemical plants all over the world.
- ITM Power appear to have tapped the UK Government for money to fund thorough testing of the 5 MW Gigastack electrolyser.
- Enough wind power from Hollandse Kust Noord, should be generated by 2025.
I feel it is very much a low risk project.
Shell’s Offshore Electrolyser Feasibility Study
This is mentioned in this article in The Times, which describes Holland Hydrogen 1, where this is said.
Shell is also still involved in a feasibility study to deploy electrolysers offshore alongside the offshore wind farm. It has suggested this could enable more efficient use of cabling infrastructure.
I very much feel this is the way to go.
Postscript
I found this article on the Dutch Government web site, which is entitled Speech By Prime Minister Mark Rutte At An Event Announcing The Construction Of Holland Hydrogen 1.
This is an extract.
By building Holland Hydrogen 1, Shell will give the Dutch hydrogen market a real boost.
So congratulations are in order.
And this is only the beginning.
Because countless companies and knowledge institutions are working now to generate the hydrogen economy of tomorrow.
The government is supporting this process by investing in infrastructure, and by granting subsidies.
Because we want to achieve our climate goals, though the war in Ukraine won’t make it any easier.
We want to reduce our dependence on Russian gas.
We want the Netherlands to lead the way in the European energy transition.
And all these ambitions are combined in the Holland Hydrogen 1 project.
Mark Rutte seems to believe in hydrogen.
Conclusion
This is a very good example of the sort of large electrolyser, we’ll be seeing all over the world.
In fact, if this one works well, how many 200 MW electrolysers will Shell need all over the world?
Will they all be identical?
Bluebell Heritage Railway Planning Western Extension
The title of this post, is the same as that of this article on Ian Visits.
This is the introductory paragraph.
The Bluebell Railway, a heritage railway that runs through Sussex has filed a pre-planning application as it seeks to extend the railway westwards along a partially disused railway alignment.
It seems to be a well-thought out plan.
- Part of the route is a freight line to bring aggregates out of the area.
- The Bluebell Railway appear to have been talking to Hanson Aggregates and the plan would not appear to affect Hanson’s business.
- The eventual destination is Haywards Heath station, where from maps and Wikipedia, it appears that not too much work would need to be done.
A Hayward’s Heath connection would surely be good for the finances of the Bluebell Railway.
I also suspect that Hanson Aggregates would come out of this with a certain amount of good publicity.
Do Network Rail Have A Plan To Increase Capacity South Of Oxted?
In Kent Railway Viaduct Set For £3.5m Makeover, I wrote about Network Rail giving a viaduct a makeover, that will last for the next fifty years.
Could a reason for the makeover, be that once the trains to Uckfield are zero-carbon, there is a possibility that the frequency of trains on the route could be doubled to two trains per hour (tph)? This would surely increase the stresses and strains on the viaduct. Especially, if two trains were timetabled to pass in Ashurst station, where the line is double-track.
This would increase the trains North of Oxted station in the Off Peak from one train to Victoria and one to London Bridge to one to Victoria and two to London Bridge. Once capacity at East Croydon has been increased, this would provide a fifty percent increase in trains between London and Oxted.
If the capacity is increased through East Croydon and into London, I can see more people using the trains into London from Oxted and the South.
But there are some missing links.
- Both London Bridge and Victoria don’t have easy connections to the Elizabeth Line.
- Getting between Heathrow and Oxted is a double-change.
- There doesn’t appear to be large amounts of parking, on the Oxted Line.
- It also doesn’t look like there are obvious places to add stations.
I also suspect that faster electric or battery-electric trains working the Uckfield branch will attract more passengers.
Various solutions must be possible after an increase in capacity at East Croydon station.
- As someone, who lives at the Northern end of the East London Line, we only have a connection to West Croydon station, rather than the much more useful East Croydon station. Will this change, after a remodelled East Croydon station?
- In Major Upgrade Planned For Norwood Junction Railway Station, I wrote about possible improvements at Norwood Junction station. This upgrade would surely allow better connection between Southern, Overground and Thameslink, with the latter two lines giving access to the Elizabeth Line.
- I also think that there could be more scope for trains to and from the South to stop at New Cross Gate station for interchange with the Overground.
It should also be noted that the Uckfield branch could become a twelve-car electrified branch.
Thameslink To Uckfield?
There has been talk of increasing the frequency of Thameslink through London from its current 20 tph. As Thameslink, already runs to Oxted and East Grinstead in the Peak, perhaps Thameslink could take over the Uckfield Branch?
- This would give direct access to the Elizabeth Line at Farringdon station.
- Services would still serve East Croydon and London Bridge.
- There would also be direct access to Eurostar services at St. Pancras.
Blackfriars, Cannon Street, Charing Cross, Euston, King’s Cross, Liverpool Street, Moorgate, Paddington, St. Pancras, Victoria and Waterloo would all be easy journeys, with no more than a single step-free change.
The service could even use the existing trains, if Hurst Green to Uckfield were to be upgraded with 25 KVAC overhead electrification. I would use lightweight catenary like this.
Trains would change over in Hurst Green station.
An East Grinstead And Oxted Shuttle
Could East Grinstead services be improved by adding a shuttle between East Grinstead and Oxted?
- It would use the bay platform at Oxted station.
- The timings would be arranged so there was an easy interchange.
- East Grinstead and Oxted is electrified.
- Oxted station is a step-free station.
- The current service takes seventeen minutes between East Grinstead and Oxted, so an hourly service would be possible, which would mean both Uckfield and East Grinstead branches had a two tph service.
Such a service could certainly have possibilities.
How Does This Help The Bluebell Railway?
This map from OpenRailwayMap shows the proposed extension.
Note.
- Horsted Keynes station is in the North-East corner of the map.
- The Bluebell Railway runs North-South through this station.
- Haywards Heath station is in the South-West corner of the map.
- The Brighton Main Line runs North-South through this station.
- Copyhold junction, which is to the North of Haywards Heath station, is where a short branch line serves Hanson Aggregates.
The proposed extension will run between the Hanson Aggregates site and Horsted Keynes station.
In my view, the obvious service would be to run between Haywards Heath and Oxted.
- Haywards Heath station has been designed to turn trains.
- Oxted station has a bay platform.
- The route is electrified between Oxted and East Grinstead.
- Copyhold Junction and Haywards Heath is electrified.
- Only about thirteen miles of the route are not electrified.
- The route services Lingfield racecourse and of course the Bluebell Railway.
Passenger numbers are incredibly hard to predict, but I believe that an hourly service could be very useful to some.
What Trains Could Be Used Between Oxted And Haywards Heath?
I wrote The Future Of The Class 387 And Class 379 Trains in February 2022 and in that post, I mused about the future of two fleets of excellent Electrostars.
- In total, there are thirty Class 387 trains and a hundred and seven Class 387 trains.
- Some of these trains are just sitting in sidings, which isn’t very productive for their owners.
- One of the owners of some of the Class 387 trains, is Porterbrook, who are not afraid to innovate.
In the July 2022 Edition of Modern Railways, there is an interview with Southeastern Managing Director; Steve White, under a title of Southeastern Under The State.
This is said on page 75.
More positive is the outlook for restoration of passenger services on the Hoo branch, where 12,000 new houses are proposed and Medway Council is looking to build a new station halfway down the branch to serve them. As the branch is unelectrified, one idea that has been looked at is a shuttle with a Vivarail battery train or similar, turning round at Gravesend or another station on the main line.
Steve White worries that this could mean spending a lot of money on infrastructure work and ending up with what would be a sub-optimal solution. ‘Do people really want to sit on a train for 10 minutes before having to get out and change onto another train? I don’t think so. Ideally what you want is through trains to London, by extending the Gravesend terminators to Hoo.’
That would require a battery/third rail hybrid unit, but Mr. White thinks that is far from an outlandish proposal; with Networker replacement on the horizon, a small bi-mode sub-fleet could dovetail neatly with a stock renewal programme. Medway Council and rail industry representatives are working on coming up with a solution for Hoo that could do what it does best; facilitating economic regeneration in a local area.
One solution for the battery/third rail hybrid unit to Hoo, would be a battery/electric four-car Class 387 or Class 379 train, which could run in formations of four, eight or twelve cars.
These trains would also be ideal for the Marshlink Line and would surely be able to handle the thirteen miles without electrification on the route between Oxted and Haywards Heath.
The sooner, someone makes a decision about some four-car battery-electric trains, the sooner we can see if they are a useful solution.
Rolls-Royce Lists Sites For New Reactor
The title of this post, is the same as that of this article on The Times.
The headline is a bit misleading, as the site is for a factory to build the reactors.
These paragraphs list the sites.
Rolls-Royce, the engineering company, has shortlisted six sites for a factory that will build its proposed small nuclear reactors.
The constituency of Rishi Sunak, the chancellor, in Richmond, North Yorkshire, is among the locations, which have been whittled down from more than 100 proposals.
The other sites are Sunderland, Deeside in Wales, Ferrybridge in West Yorkshire, Stallingborough in Lincolnshire, and Carlisle.
As Rishi Sunak resigned last night, does that rule out Richmond?
I feel that Rolls-Royce will choose this location with care, as any good company would.
I have a few thoughts.
Will Rolls-Royce Go For Zero-Carbon Manufacture?
If you intend to build large numbers of small modular nuclear reactors, it is not a good idea from a marketing or public relations point of view to release tonnes of carbon in their manufacture.
This page on the Rolls-Royce web site has a title of Destination Net Zero, where this is said.
We have already pledged to reduce emissions from our own operations to net zero by 2030, and to play a leading role in enabling the sectors in which we operate to reach net zero by 2050. Now, we are now laying out our technology pathway and setting clear short-term targets to show how we will achieve those goals.
I am sure Rolls-Royce will go for zero-carbon manufacture.
This will probably mean the site will need to have access to the following.
- Renewable electricity from wind, solar or hydro.
- Hydrogen
- Zero-carbon steel, copper and other raw materials
An external supply of hydrogen may well be the least important, as they recently purchased a German electrolyser developer and manufacturer, that I wrote about in Rolls-Royce To Develop mtu Hydrogen Electrolyser And Invest In Hoeller Electrolyser.
Will The Factory Have A Rail Connection?
A rail connection could have four main purposes.
- Bringing in raw materials like steel.
- Delivering manufactured components to site.
- If the factory is a major source of employment, rail is the greenest way to bring in staff from further away.
- If large shipments are brought in and delivered by zero-carbon rail, it generally doesn’t annoy the locals.
Note.
- The huge Britishvolt gigafactory at Blyth will have a rail connection for the transport of lithium and finished batteries.
- Transport of nuclear fuel and waste around the UK is generally done by train, with perhaps the last few miles by truck.
I think it will be very unlikely, that the new factory will not have a rail connection.
Will Power Station Modules Be Transportable By Rail?
Given that in the UK, there will need to be a railhead at or near the power station for fuel and waste, I believe that if modules were transportable by rail, this could give big advantages to the roll-out of the reactors.
If a former Magnox nuclear site like Bradwell is to be home to a fleet of small modular reactors, the electrified railhead is already in place at Southminster station.
The crane and the track probably need a bit of a refurbishment, but overall, it looks in reasonable condition.
If you sell nuclear as zero-carbon, rail is the easiest way to ensure zero-carbon delivery of modules.
The standard loading gauge in the UK is W10, which is 2.9 metres high and 2.5 metres wide.
- A standard twenty-foot container is six metres long, which must help.
- W10 gauge allows the transport of standard Hi-Cube shipping containers, which are 9 ft 6 in. high, on flat rail wagons.
- If the modules can fit into Hi-Cube shipping containers, this would make transport easier everywhere, as all ports and railways can handle these containers.
Would it be possible to fit all components into this relatively small space?
It could be difficult, but I suspect it is possible to achieve, as it would make the reactors easier to sell.
- Sites would only need to be able to receive Hi-Cube shipping containers.
- These could be trucked in from a nearby railhead.
- Containers on a railway are a very secure way of transporting goods.
- Rolls-Royce has masses of experience in shipping large turbofan engines in standard shipping containers. Some are shipped in very carefully controlled air conditions to minimise damage.
- Hi-Cube shipping containers can go through the Channel Tunnel.
I am fairly sure, that Rolls-Royce are designing the power station, so that it fits into a number of Hi-Cube shipping containers. It would give other advantages.
- Smaller components would probably speed up assembly.
- Smaller components may also mean that smaller cranes could be used for assembly.
There may need to be some gauge enhancement to be able to access some sites in the UK.
- This article on Rail Engineer, is entitled Showing Your Gauge, and it details how gauge is being enhanced to W10 and W12 in the UK.
- Network Rail have also published a map, which shows where W10 gauge is possible. Click here to view.
I am fairly certain, that most railways in the world can handle Hi-Cube shipping containers.
Availability Of Staff
Rolls-Royce will obviously opt for a place, where there is good availability of staff.
Conclusion
I feel that any of the sites mentioned could be the ideal place for the factory.
If I had to have a bet, I’d put it the factory at Stallingborough in Lincolnshire.
- It is close to the Zero Carbon Humber energy and hydrogen hub.
- There is plenty of space.
- There is a rail connection.
- It is close to the Port of Immingham.
- It is close to British Steel at Scunthorpe.
It is also not that far from Derby by road or rail.
Climate Change: ‘Sand Battery’ Could Solve Green Energy’s Big Problem
The title of this post, is the same as that of this article on the BBC.
This is the introductory paragraph.
Finnish researchers have installed the world’s first fully working “sand battery” which can store green power for months at a time.
The article then gives a detailed explanation about how the battery works.
Note.
- The article does not give any details on battery capacity.
- The heat stored in the battery is extracted as hot water.
- The Finnish company is called Polar Night Energy.
In Bang Goes My Holiday!, I described the Siemens Gamesa ETES, which appears to work on similar principles, to the Finnish battery.
This document on the Siemens Gamesa web site describes that installation.
- The nominal power is 30 MW.
- The storage capacity is 130 MWh.
- Siemens use volcanic rock as the storage medium.
- 80 % of the technology is off the shelf.
The picture on the front says “Welcome To The New Stone Age”.
The BBC have published a video of the Polar Night Energy Battery.
