H2ercules
H2ercules is a project that will create the German hydrogen network.
The H2ercules web site, introduces the project with these two paragraphs.
A faster ramp-up of the hydrogen economy in Germany is more important than ever in order to drive forward the decarbonisation programme, put the German energy system on a more robust footing, and thus contribute towards a green security of supply. What this needs is a geographical realignment of the infrastructure for energy in gas form: Instead of flowing from the east of Germany to the west and south of the country, the gas – natural gas now, hydrogen in the future – will have to make its way in future from generation locations in the north-west to centres of consumption located mainly in the west and south. That also means that new sources will have to be connected, and gaps in existing pipeline networks will have to be closed. To speed up this vital process, OGE and RWE have developed the national infrastructure project “H2ercules”, which is intended to supply consumers in Germany’s south and west with domestically produced green hydrogen from the north of the country, in addition to imported sources. This will involve connecting up the electrolyser capacities that are currently being planned and developing more besides. RWE wants to create up to 1 GW of additional electrolyser capacity as part of the H2ercules project. For the connection component, OGE is planning to put 1,500 km of pipelines in place. For the most part, this will mean converting pipelines from the existing natural gas network to hydrogen, supplemented by newly constructed facilities. Converting natural gas pipelines is not only the more cost-efficient solution, but it also allows for a faster schedule. The system is expected to be supplemented by the planned hydrogen storages of RWE.
The current plan is to complete the project in three stages between 2026 and 2030, in order to connect industries to the hydrogen supply as soon as possible. The aim of this collaboration across multiple value levels is to resolve the chicken-and-egg problem on a super-sized scale and also smooth the way forward for other projects.
Note.
There will be a lot of conversion of the existing natural gas network to hydrogen.
RWE wants to create up to 1 GW of additional electrolyser capacity as part of the H2ercules project.
The second paragraph indicates to me, that they want to move fast.
This map from the H2ercules web site, indicate the proposed size of the network in 2030.
These three paragraphs describe how H2ercules will be developed.
OGE and RWE are both strong companies that aim to combine forces as part of the H2ercules project in order to overcome this Herculean task. While the task for OGE will be to convert the required gas pipelines to hydrogen and construct new pipelines, RWE will expand its electrolyser capacity and import green hydrogen in addition. Gas-fired power stations with a capacity of at least 2 GW will be converted to hydrogen, and new H2 -storages as well as H2-storages repurposed from gas storages on the Dutch border will be connected to the hydrogen supply system.
H2ercules also opens up new opportunities to connect Germany’s future centres of hydrogen consumption to key import routes, first via pipelines from Belgium and the Netherlands, and later via Norway and also from southern and eastern Europe, with the added prospects of import terminals for green molecules in Germany’s north. The project is thus contributing significantly to the creation of a European hydrogen market.
The first additional companies and organisations have already indicated their interest in this project, and it is expected that in the future smaller businesses will benefit in addition to large-scale customers, as the entire industry is guided towards a decarbonised future.
These are my thoughts.
Why Is It Called H2ercules?
I suspect, it’s nothing more, than the Germans wanted a recognisable and catchy name.
- Name selection is not helped by the German for hydrogen, which is wasserstoff.
- Hercules is Herkules in German, which doesn’t really help.
- Projekt Wasserstoff isn’t as memorable as H2ercules, which at least isn’t English.
It looks to me, that the Germans have come up with a good acceptable compromise.
The Wilhemshaven Hydrogen Import Terminal
German energy company; Uniper is building a hydrogen import terminal at Wilhemshaven to feed H2ercules and German industry with hydrogen from places like Australia, Namibia and the Middle East. I wrote about this hydrogen import terminal in Uniper To Make Wilhelmshaven German Hub For Green Hydrogen; Green Ammonia Import Terminal.
Wilhelmshaven and Great Yarmouth are 272 miles or 438 kilometres apart, so a pipeline or a tanker link would be feasible to export hydrogen from Notfolk to Germany.
I suspect RWE will build a giant offshore electrolyser close to the Norfolk wind farms and the hydrogen will be exported by tanker or pipeline to Germany or to anybody else who pays the right price.
RWE’s Norfolk Wind Farms
What is interesting me, is what Germany company; RWE is up to. Note they are one of the largest UK electricity producers.
In December 2023, they probably paid a low price, for the rights for 3 x 1.4 GW wind farms about 50 km off North-East Norfolk from in-trouble Swedish company; Vattenfall and have signed contracts to build them fairly fast.
In March 2024, I wrote about the purchase in RWE And Vattenfall Complete Multi-Gigawatt Offshore Wind Transaction In UK.
This map from RWE shows the three wind farms, with respect to the Norfolk coast.
Could it be, that RWE intend to build a giant offshore electrolyser to the East of Great Yarmouth?
- The planning permission for an electrolyser, which is eighty kilometres offshore, would be far easier, than for one onshore.
- The hydrogen pipeline between Norfolk and Germany would be less than 400 kilometres.
- Hydrogen could also be brought ashore in Norfolk, if the price was right.
- The Bacton gas terminal is only a few miles North of Great Yarmouth.
But the big advantage, is that the only onshore construction could be restricted to the Bacton gas terminal.
Adding More Wind Farms To The Electrolyser
Looking at the RWE map, the following should be noted.
South of Norfolk Vanguard East, there is the East Anglian Array wind farm, which by the end of 2026, will consist of these wind farms.
- East Anglia One – 714 MW – 2020
- East Anglia One North – 800 MW – 2026
- East Anglia Two – 900 MW – 2026
- East Anglia Three – 1372 MW – 2026
Note.
- The date is the commissioning date.
- There is a total capacity of 3786 MW
- All wind farms are owned by Iberdrola.
- There may be space to add other sections to the East Anglian Array.
I doubt, it would be difficult for some of Iberdrola’s megawatts to be used to generate hydrogen for Germany.
To the East of Norfolk Boreas and Norfolk Vanguard East, it’s Dutch waters, so I doubt the Norfolk cluster can expand to the East.
But looking at this map of wind farms, I suspect that around 4-5 GW of new wind farms could be squeezed in to the North-West of the the Norfolk Cluster and South of the Hornsea wind farms.
The 1.5 GW Outer Dowsing wind farm, which is being planned, will be in this area.
I can certainly see 8-10 GW of green electricity capacity being available to electrolysers to the North-East of Great Yarmouth.
Conclusion
UK offshore electricity could be the power behind H2ercules.
- The hydrogen could be sent to Germany by pipeline or tanker ship, as the distance is under 400 kilometers to the Wilhelmshaven hydrogen hub.
- Extra electrolysers and wind farms could be added as needed.
- The hydrogen won’t need to be shipped halfway round the world.
The cash flow won’t hurt the UK.

Highland Council Greenlights West Of Orkney Windfarm Onshore Plans
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Highland Council has approved the onshore plans of the 2 GW West of Orkney Windfarm project, being developed by TotalEnergies, Corio Generation, and Renewable Infrastructure Development Group (RIDG) in Scotland.
These are the first three paragraphs.
The onshore application for planning permission in principle was approved on 4 June and outlines the underground cables and electrical infrastructure required to connect the offshore wind farm to the national transmission network.
Last year, the project became the first ScotWind proposal to submit both its offshore consent application to Scottish Ministers and its onshore planning application to The Highland Council.
The onshore application provides information on proposed cable landfalls on the north Caithness coast, the project’s substation at Spittal in Caithness, and the underground cables which will extend around 25 kilometres and connect to the substation.
According to the project page of the West of Orkney wind farm web site, the target for commissioning of the wind farm is 2029.
This wind farm appears to be making a play to be the first of the ScotWind Leasing developments to be commissioned.
I have some thoughts.
Converting The Flotta Oil Terminal To The Flotta Hydrogen Hub
This first paragraph of the Wikipedia entry for the Flotta Oil Terminal, describes it like this.
The Flotta oil terminal is a major crude oil reception, processing, storage and export facility on the island of Flotta, in the south of Scapa Flow in the Orkney Islands. It receives and processes crude oil delivered by a subsea pipeline from the Piper, Claymore, Tartan and Golden Eagle platforms and associated fields. The terminal includes facilities for exporting stabilised crude oil (and formerly liquefied petroleum gases) by tanker.
It is now proposed to add the Flotta Hydrogen Hub to the Flotta Oil Terminal.
This document on the Repsol web site, describes the Flotta Oil Terminal.
- This page is the Flotta Hydrogen Hub web site.
- This page discusses, what will be done with the green hydrogen produced by electrolysis.
- The green hydrogen page, has an excellent map of the hydrogen and electricity flows to and from the Flotta Hydrogen Hub.
The Flotta Oil Terminal will be developed into a major hydrogen production and distribution facility.
UK Offshore Wind In 2030
The next general election is likely to be held in 2029, so how much wind energy will be added during the next Parliament?
The Current Position
The Wikipedia entry for the list of operational wind farms in the UK, says this.
In October 2023, there were offshore wind farms consisting of 2,695 turbines with a combined capacity of 14,703 megawatts.
Due To Be Commissioned In 2024
It would appear these wind farms will come on-line in 2024.
- Neart Na Gaoithe – 450 MW – Fixed
- Doggerbank A – 1235 MW – Fixed
- Doggerbank B – 1235 MW – Fixed
This would add 2920 MW to give a total of 17,623 MW.
Due To Be Commissioned In 2025
It would appear these wind farms will come on-line in 2025.
- Moray West – 882 MW – Fixed
- Doggerbank C – 1218 MW – Fixed
This would add 2100 MW to give a total of 19,723 MW.
Due To Be Commissioned In 2026
It would appear these wind farms will come on-line in 2026.
- Sofia – 1400 MW – Fixed
- East Anglia 3 – 1372 MW – Fixed
- East Anglia 1 North – 800 MW – Fixed
- East Anglia 2 – 900 MW – Fixed
- Pentland – 100 MW – Floating
This would add 4572 MW to give a total of 24,295 MW.
Due To Be Commissioned In 2027
It would appear these wind farms will come on-line in 2027.
- Hornsea 3 – 2852 MW – Fixed
- Norfolk Boreas – 1380 MW – Fixed
- Llŷr 1 – 100 MW – Floating
- Llŷr 2 – 100 MW – Floating
- Whitecross – 100 MW – Floating
This would add 4532 MW to give a total of 28,827 MW.
Due To Be Commissioned In 2028
It would appear these wind farms will come on-line in 2028.
- Morecambe – 480 MW – Fixed
This would add 480 MW to give a total of 29,307 MW.
Due To Be Commissioned In 2029
It would appear these wind farms will come on-line in 2029.
- West Of Orkney – 2000 MW – Fixed
This would add 2000 MW to give a total of 31,307 MW.
Due To Be Commissioned In 2030
It would appear these wind farms will come on-line in 2030.
- Ramplion 2 Extension – 1200 MW – Fixed
- Norfolk Vanguard East – 1380 MW – Fixed
- Norfolk Vanguard West – 1380 MW – Fixed
- Awel y Môr – 1100 MW – Fixed
- Berwick Bank – 4100 MW – Fixed
- Outer Dowsing – 1500 MW – Fixed
- Hornsea 4 – 2600 MW – Fixed
- Caledonia – 2000 MW – Fixed
- N3 Project – 495 MW – Fixed/Floating
This would add 15755 MW to give a total of 47.062 MW.
Capacity Summary
- 2023 – None – 14703 MW
- 2024 – 2920 MW – 17,623 MW
- 2025 – 2100 MW – 19,723 MW
- 2026 – 4572 MW – 24,295 MW
- 2027 – 4532 MW- 28,827 MW
- 2028 – 480 MW – 29,307 MW
- 2029 – 2000 MW – 31,307 MW
- 2030 – 15755 MW – 47,062 MW
Note that capacity has increased more than threefold.
If we assume the following.
- New wind farms are commissioned throughout the year.
- 14703 MW of wind power, with all our gas-fired, nuclear and onshore wind farms is enough to power the UK.
- The average capacity factor is 45 %.
- The strike price is £35/MWh.
The levels I have set are deliberately on the low side.
The amount of energy and cash flow generated by new wind farms in a year can be calculated as follows.
{Average New Capacity In Year}= ({Capacity at Year Start}+{Capacity at Year End})/2-14703
{Extra Electricity Generated In Year}= {Average New Capacity In Year}*365*24*{Capacity Factor}
{Cash Flow}={Extra Electricity Generated In Year} * {Strike Price}
The following figures are obtained.
- 2024 – 1460 MW – 5,755,320 MWh – £ 201,436,200
- 2025 – 3970 MW – 15,649,740 MWh – £ 547,740,900
- 2026 – 7306 MW – 28,800,252 MWh – £ 1,008,008,820
- 2027 – 11858 MW – 46,744,236 MWh – £ 1,636,048,260
- 2028 – 14,364 MW – 56,622,888 MWh – £ 1,981,801,080
- 2029 – 15,604 MW – 61,510,968 MWh – £ 2,152,883,880
- 3030 – 23,931.5 MW – 94,337,973 MWh – £ 3,301,829,055
Nate.
- The first column is the cumulative amount of new capacity about the 14,703 MW in December 2023.
- The second column is the extra electricity generated in the year over December 2023.
- The third column is the extra cash flow in the year over December 2023.
As the installed base of wind farms increases, the cash flow increases.
It should also be noted that there are a large number of wind farms, already pencilled in for 2031-2035.
What Will We Do With All This Extra Electricity?
We need more industries that will consume a lot of electricity, like cement, chemicals and steel.
But I suspect that the easiest thing to do, is to convert the excess electricity to hydrogen and export it to the Continent and especially the Germans by pipeline or tanker.
Conclusion
Whoever wins this year’s General Election, should have a growing source of revenue for the life of the parliament and beyond.
Audacious’ Contract To Revive Nancy – Contrexéville Route
The title of this post, is the same as that of this article on Railway Gazette.
These first two paragraphs give more details of the project.
The 89 km route from Nancy to Contrexéville, much of which has been closed to passenger and freight traffic since 2016, is to reopen in December 2027. This follows the award by the Grand Est regional council on May 24 of a contract to a private-sector consortium formed of Transdev SA, NGE Concessions and Caisse des Dépôts et Consignations.
The ‘audacious’ 22-year concession deal is worth €721m and covers both rehabilitation of the line at a cost of €150m plus management of the infrastructure and operations. Following detailed studies, work on the ground is expected to start in April 2025.
This OpenRailwayMap shows the route.
Note.
- Nancy is at the top of the map in the middle.
- Contrexéville is in the South-West corner of the map.
- Vuttel is shown by the blue arrow.
- The distance between Nancy and Contrexéville is 89 kilometres.
- It appears to be a double-track railway.
As the picture in the Railway Gazette article shows, the route needs to be refurbished.
These are my thoughts.
The Route Will Be Operated By An Augmented Form Of Open Access
- An augmented form of open access will seem to be used to run services.
- The infrastructure will be donated to the regional government.
- Upwards of a dozen round trips per day will be run.
Nothing is said about the traction to be used!
Modernised, it could be an interesting route for tourism.
Will It Provide A New Route Between Metz and Dijon?
Consider.
Metz with TGV connections, is not far to the North of Nancy.
Dijon with TGV connections, is not far to the South of Contrexéville.
These connections could be invaluable for tourism and development of the area.
This map shows the South-Western section of the route between Contrexéville and Vittel.
Note.
- Vittel is marked by the blue arrow in the North-East corner of the map.
- Contrexéville is in the South-West corner of the map.
- In the middle of the map are sidings, which are marked Nestlé Waters.
- There appear to be sidings at Contrexéville and Vittel
In From 2025, Nestlé Waters France Will Use The First Hydrogen-Powered Freight Train Through An Innovative Solution Developed by Alstom and ENGIE, I talk about how Nestlé will move water from the Vosges, using hydrogen-hybrid locomotives pulling freight trains.
This is a visualisation of the train.
This is said in the original Alstom press release.
From 2025, this freight train powered by electricity from the rail network and from hydrogen in non-electrified sectors will aim to progressively ensure the transport of VITTEL® natural mineral water between the factory located in the Vosges and its various distribution centers in France (i.e Vittel/Arles 600 kms and Vittel/Montreuil-Bellay 760 kms). The dual-mode solution will be composed by a generator wagon incorporating a high-power fuel cell system powered by renewable hydrogen and a line-electric locomotive, all connected by an electrical power cable. The generating wagon will be able to supply the locomotive with electricity in the without the need for any catenary.
It does appear, that within a year or to, freight trains from between Contrexéville and Vittel will be hauled by hydrogen-hybrid locomotives.
- Trains to and from Montreuil-Bellay could go via Nancy or Contrexéville.
- Trains to and from Arles could go via Contrexéville.
I suspect at present all trains have to go via Contrexéville.
If the Nancy and Contrexéville route were to be rebuilt and could take the water trains, this would open up routes to the Channel Ports and Belgium, Luxembourg, Northern France, Northern Germany and The Netherlands.
- Hydrogen trains would certainly advertise the zero-carbon nature of the transport.
- It has to be remembered that a couple of years ago, Highland Spring opened a rail distribution facility in Scotland, with the aim of moving 40 % of their water by rail.
I wonder if Nestlé are building a zero-carbon rail network for the delivery of their bottled waters.
What Traction Would Be Used For Passenger Trains?
Consider.
- The distance between Nancy and Contrexéville is 89 km or 55 miles.
- This distance, is within the range for battery-electric and hydrogen-powered trains.
- There is reason to believe that Nestlé’s water trains will be hydrogen-powered.
I suspect either battery-electric and hydrogen-powered trains could be used.
Recurrent Energy’s Middle Road Project Sold To Centrica
The title of this post, is the same as that pf this article on Solar Power Portal.
These are the first two paragraphs.
Recurrent Energy, a global solar and energy storage developer and a subsidiary of Canadian Solar, announced the sale of its 49.9 MWp Middle Road solar project in Harbury, Warwickshire, to Centrica Business Solutions. The subsidy-free project, slated for construction this summer, will commence operations in 2025.
The Middle Road project is just one piece of Recurrent Energy’s expanding UK pipeline, which boasts over 2.6 GWp of solar PV and 6.7 GWh of battery storage projects. This mirrors the broader trend of increased investment in UK solar. Indeed, Recurrent announced €1.3 billion of financing for EU and UK solar projects earlier this week.
This 49.9 MW solar project shows three ways to make money from a solar project.
The Developer
Recurrent Energy would appear to have developed the expertise to put together these solar farms and do all the legals and administration to connect them to the National Grid.
They obviously can show their financial backers, the cash flow, that the farms generates.
So if you’re good at building solar farms, I suspect you can develop a substantial pipeline of projects, each with their own case flow.
The Operator
Initially in the early days, Recurrent Energy will probably be the operator, so they can sort out any teething problems and build the financial profile of the site.
The Owner
But as at Middle Road, they may decide to cash in their investment.
Centrica have now taken over the ownership and they can operate the farm themselves or pay, Recurrent Energy a fee.
Note.
- Developer, operator and owner all have ways of making money from this solar farm.
- Developer and owner can use the solar farm, as an asset on which to raise money.
- Similar cash flows and inside probably apply to batteries and wind farms.
By buying, selling and updating the various assets, a financial operator, can use their assets to make money.
As Centrica are also an electricity supplier, they can probably suggest to developers, where a solar farm or battery-electric storage system is needed.
Are Centrica Developing A Pipeline Of Projects?
In Centrica Set For Solar Boost With Acquisition Of Two Projects In South-West England, I talked about how Centrica had acquired two projects in South-West England.
The Middle Road project is the third project that Centrica has purchased this year.
As a Control and Electrical Engineer, I know, that by careful management of the assets, Centrica can achieve the following.
- Delivery of electricity to their customers at a competitive price.
- If a battery is included in the local grid, higher supply reliability can be achieved.
- Batteries also allow the local network to carry out other tasks, like frequency stabilisation.
The flexibility of the local network should allow other assets to be added.
Teesworks Joins Forces With NatPower On 1GW UK BESS
The title of this post, is the same as that of this article on Solar Power Portal.
These are the first two paragraphs.
Teesworks, the UK’s largest industrial zone, has revealed plans for a 1GW battery energy storage system (BESS) in partnership with renewables developer NatPower.
The project will be constructed over 50 acres of the Long Acres section of the 4500-acre Teesworks site. Construction costs are expected to total around £1 billion. While the main plan for the BESS is focused on renewable energy storage, the company also noted that the system could also support electric vehicle (EV) charging in the future.
The article then lists several large BESS projects, that are under development.
It also suggests that investment in batteries is in a healthy state.
Council Wants To Only Serve Vegan Food At Events
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A West Yorkshire council will only provide vegan food at its meetings and events if a new catering plan is approved.
These three paragraphs explain the policy.
Calderdale Council wants its menus to be entirely plant-based, with a preference for seasonal and non-processed foods.
The council adopted a climate change emergency policy in 2020, which included a commitment to using plant-based catering.
Senior councillors will be asked to recommend that the vegan food scheme is adopted at a meeting on 3 June.
I am coeliac and have to eat a gluten-free diet. Sometimes, I will eat meals marked as vegan, but only after I have checked they are gluten-free.
A couple of times in my life, I have been told that I will be fine with a restaurants’s organic vegan food.
These incidents weren’t in the UK and I quickly moved on to a restaurant, which served food, that I could eat.
But you don’t know, where these sort of restrictions will lead.
- Suppose a Muslim-dominated council, insisted that all women kept their hair covered.
- Or all butcher’s shops in the area were to be closed!
- Will the local hosputal have to serve vegan food?
Any restaurant or catering facility, must serve, what its patrons want or need to eat.
Brand New Battery Technology To Be Trialled On TransPennine Train
The title of this post, is the same as that of this press release from Hitachi.
These three bullet points, act as sub-headings.
- First-ever trial in the UK to replace a diesel engine with a battery on an intercity train is underway.
- Pioneering collaboration between Angel Trains, TransPennine Express, Turntide Technologies and Hitachi Rail.
- Hitachi Rail has built a battery using the North East supply chain, with one battery unit predicted to reduce emissions and fuel costs by as much as 30%.
These are my thoughts on some of the paragraphs in the press release.
The First Paragraph
This is the first paragraph.
Testing of the UK’s first intercity battery train commenced earlier today. The battery, which generates a peak power of more than 700kw, has now been successfully retrofitted onto a TransPennine Express ‘Nova 1’ train (five-carriage intercity Class 802), ahead of the trial on Transpennine routes this summer.
Each of the three diesel power packs in on of TransPennine Express’s Class 802 trains can generate 700 kW, so the battery packs can provide the same power as the current Rolls-Royce mtu diesel power packs.
The Third Paragraph
This is the third paragraph.
The single battery unit is incredibly powerful, storing enough electricity to power more than 75 houses for a day. This impressive energy and power density will deliver the same levels of high-speed acceleration and performance, while being no heavier than the diesel engine it replaces.
This equity of high-speed acceleration and performance is to be expected, as the train power and weight is the same, if the power is diesel engines or batteries.
The Fourth Paragraph
This is the fourth paragraph.
The installation of a battery will reduce emissions and improve energy efficiency. It is predicted to reduce emissions and fuel costs by as much as 30% on a Hitachi intercity train.
I would assume that this improvement in emissions and fuel costs, is due to the use of regenerative braking to recharge the batteries, when the train slows down.
The Fifth Paragraph
This is the fifth paragraph.
Most importantly for passengers, the trial will test how intercity trains can enter, alight and leave non-electrified stations in zero-emission battery mode to improve air quality and reduce noise pollution.
As the trains enter a non-electrified station, the regenerative braking will recharge the batteries to both power the train in the station and accelerate the train on its way.
The Seventh Paragraph
This is the seventh paragraph.
The trial will provide real-world evidence to inform the business case for a 100% -battery-electric intercity train, capable of running up to 100km in battery mode. This remarkable range means this battery technology could be deployed to cover the final non-electrified sections of intercity routes in the coming years. It will also demonstrate how battery technology can reduce infrastructure costs by reducing the need for overhead wires in tunnel sections and over complex junctions.
Note that 100 kilometres is 62.1 miles.
You can never do too much real world testing!
These are my further thoughts.
Acceleration And Braking Under Battery Power
This graph from Eversholt Rail, shows the acceleration and deceleration of a five-car Class 802 electric train.
As Hitachi have said in the press release that.
- The weight of a battery pack is the same as a diesel engine.
- The power of a battery pack is the same as a diesel engine.
The acceleration and braking curve for a Class 802 train, with a single traction battery will surely be the same.
Would this mean, that if a battery-electric train replaced a diesel-electric train, the timetable would be the same?
What would be the effects, if a second diesel engine were to be replaced with a battery pack?
- The train would still weigh the same.
- The train’s performance would still be the same.
- The train would have 1400 kW of power available, but I doubt this could be used efficiently, as it might exceed the train’s performance limits.
- The train would have enough electricity for a 200 kilometre or 124.3 mile range.
There might be a need for a sophisticated control system to set the power mode, but in my experience of riding in the cab of an InterCity 125 and a Boeing 747, drivers or pilots have enough intelligence and fingers to control systems with multiple engines.
What would be the effects, if a third diesel engine were to be replaced with a battery pack?
- The train would still weigh the same.
- The train’s performance would still be the same.
- The train would have enough electricity for a 300 kilometre or 186.4 mile range.
The range is sufficient for a lot of routes.
London And Beverley
Consider.
- This route has 44.3 miles of unelectrified track between Temple Hirst Junction and Beverley.
- One battery range is 100 kilometres or 62.1 miles.
- As the trains have three slots for battery packs or diesel engines, they could always carry a diesel engine for emergencies.
The route could be run in one of two ways.
- By using one battery, that would be charged at Beverley.
- By two batteries, that would be charged on the main line to the South of Temple Hirst Junction. One battery would be used in each direction.
Note.
- The second method would not require any new infrastructure at Beverley or Hull.
- All batteries would be identical 100 km batteries.
- Trains would just swap an appropriate number of diesel engines for batteries.
The service could run as soon as the trains had the power transplants.
Using The Lincoln Diversion
In Extra Luggage Racks For Lumo, I also talked about Lumo taking the diversion via Lincoln.
Consider.
- This route is 88.5 miles of unelectrified track.
- It would be possible to be handled by a Class 802 train with two battery packs.
- Hull Trains will need battery packs to get to Beverley.
- Some LNER services will use battery packs.
Perhaps trains will use one battery to Lincoln and one from.
Crewe And Holyhead
In October 2023, the government said, that the North Wales Coast Line would be electrified.
Consider.
- Crewe and Holyhead are 105.5 miles apart.
- The route currently has no electrification.
- It has been planned to electrify the 21.1 miles between Crewe and Chester for some time.
- A lot of the route West of Chester may arouse the wrath of the Nimbies and be politically difficult to electrify, as castles and electrification don’t mix.
- Llandudno Junction station might be a station, where trains could be charged.
- Shotton and Chester stations need rebuilding.
- The line is not short of electric power, because of Electric Mountain and the windfarms along the coast.
- The route will soon be served by Hitachi Class 805 trains.
I believe the North Wales Coast Line could be one of those routes, which Hitachi’s partial electrification might be ideal.
I also believe that, it could be an extension of High Speed Two from Crewe, which provided a zero-carbon route between London and Ireland.
Conclusion
I can see if the tests perform as expected, that there will be some battery express trains running soon.
Do RWE Have A Comprehensive Hydrogen Plan For Germany?
What is interesting me, is what Germany company; RWE is up to. They are one of the largest UK electricity producers.
In December 2023, they probably paid a low price, for the rights for 3 x 1.4 GW wind farms about 50 km off North-East Norfolk from in-trouble Swedish company; Vattenfall and have signed contracts to build them fairly fast.
In March 2024, wrote about the purchase in RWE And Vattenfall Complete Multi-Gigawatt Offshore Wind Transaction In UK.
Over the last couple of years, I have written several posts about these three wind farms.
March 2023 – Vattenfall Selects Norfolk Offshore Wind Zone O&M Base
November 2023 – Aker Solutions Gets Vattenfall Nod To Start Norfolk Vanguard West Offshore Platform
December 2023 – SeAH To Deliver Monopiles For Vattenfall’s 2.8 GW Norfolk Vanguard Offshore Wind Project
Then in July 2023, I wrote Vattenfall Stops Developing Major Wind Farm Offshore UK, Will Review Entire 4.2 GW Zone
Note.
- There does appear to be a bit of a mix-up at Vattenfall, judging by the dates of the reports.Only, one wind farm has a Contract for Difference.
- It is expected that the other two will be awarded contracts in Round 6, which should be by Summer 2024.
In December 2023, I then wrote RWE Acquires 4.2-Gigawatt UK Offshore Wind Development Portfolio From Vattenfall.
It appears that RWE paid £963 million for the three wind farms.
I suspect too, they paid for all the work Vattenfall had done.
This transaction will give RWE 4.2 GW of electricity in an area with very bad connections to the National Grid and the Norfolk Nimbies will fight the building of more pylons.
So have the Germans bought a pup?
I don’t think so!
Where Is Wilhemshaven?
This Google Map shows the location of Wilhemshaven.
Note.
- Heligoland is the island at the top of the map.
- The Germans call this area the Wdden Sea.
- The estuaries lead to Wilhelmshaven and Bremerhaven.
- Cuxhaven is the port for Heligoland, which is connected to Hamburg by hydrogen trains.
This second map shows between Bremerhaven and Wilhelmshaven.
Note.
- Wilhelmshaven is to the West.
- Bremerhaven is in the East.
- The River Weser runs North-South past Bremerhaven.
I’ve explored the area by both car and train and it is certainly worth a visit.
The Wilhemshaven Hydrogen Import Terminal
German energy company; Uniper is building a hydrogen import terminal at Wilhemshaven to feed German industry with hydrogen from places like Australia, Namibia and the Middle East. I wrote about this hydrogen import terminal in Uniper To Make Wilhelmshaven German Hub For Green Hydrogen; Green Ammonia Import Terminal.
I suspect RWE could build a giant offshore electrolyser close to the Norfolk wind farms and the hydrogen will be exported by tanker or pipeline to Germany or to anybody else who pays the right price.
All this infrastructure will be installed and serviced from Great Yarmouth, so we’re not out of the deal.
Dogger Bank South Wind Farm
To make matters better, RWE have also signed to develop the 3 GW Dogger Bank South wind farm.
This could have another giant electrolyser to feed German companies. The wind farm will not need an electricity connection to the shore.
The Germans appear to be taking the hydrogen route to bringing electricity ashore.
Energy Security
Surely, a short trip across the North Sea, rather than a long trip from Australia will be much more secure and on my many trips between the Haven Ports and The Netherlands, I haven’t yet seen any armed Houthi pirates.
RWE And Hydrogen
On this page on their web site, RWE has a lot on hydrogen.
Very Interesting!
H2ercules
This web site describes H2ercules.
The goal of the H2ercules initiative is to create the heart of a super-sized hydrogen infrastructure for Germany by 2030. To make this happen, RWE, OGE and, prospectively, other partners are working across various steps of the value chain to enable a swift supply of hydrogen from the north of Germany to consumers in the southern and western areas of the country. In addition to producing hydrogen at a gigawatt scale, the plan is also to open up import routes for green hydrogen. The transport process will involve a pipeline network of about 1,500 km, most of which will consist of converted gas pipelines.
Where’s the UK’s H2ercules?
Conclusion
The Germans have got there first and will be buying up all of our hydrogen to feed H2ercules.
Construction Under Way To Double Power Station Capacity At Centrica’s Brigg Energy Park
The title of this post, is the same as that of this press release from Centrica.
This is the sub-heading.
Four ultra-efficient engines have arrived at Centrica’s former combined cycle gas power station at Brigg, with construction work underway on an expansion of the peaking plant at the Lincolnshire site.
These three paragraphs give more details about the project.
The business is installing the four engines inside the former turbine hall at the power station, which was decommissioned in 2020, helping to create nearly 100MW of fast response assets capable of meeting demand when renewable generation is low.
The expanded power plant will be hydrogen-ready, and form part of a trial due to start in late 2024 to blend hydrogen into the gas, ramping up from a three per cent blend to 20 per cent, with a long term vision to move towards 100 per cent hydrogen and to deploy similar technology across all peaking plants.
Work at Brigg is expected to last around nine months and the plant will be fully operational in early 2025.
These are my thoughts.
Hydrogen Blend Operation
The second paragraph indicates that Centrica will be using Brigg power station to research the use of hydrogen blends.
Hydrogen blends could offer a way an easy way to cut hydrogen emissions, so it is good, that Centrica are researching their use in gas-fired power stations.
Brigg As A Peaking Plant
This paragraph from the press release, explains what Centrica means by a peaking plant.
Peaking plants only generate electricity when there’s high or peak demand for electricity, or when generation from renewables is too low to meet demand. Once connected to the grid, the engines will have the capacity to power 20,000 homes for a full day when required, which will maintain stability and deliver reliable power across the grid.
The second paragraph also says this.
A long term vision to move towards 100 per cent hydrogen and to deploy similar technology across all peaking plants.
Does this mean that all peaking plants will move to hydrogen-fired generation?
Brigg Redevelopment
This paragraph from the press release, outlines Centrica’s plans for Brigg power station.
Centrica is redeveloping the Brigg energy park which, once complete, will be home to a 50MW battery, commercial-scale hydrogen production using HiiROC technology (in which Centrica has a five per cent stake), and 100MW of gas peaking plant.
Note.
- I would assume that the battery, will be able to provide 50 MW for at least two hours, so the battery electric storage system (BESS) will be at least a 50 MW/100 MWh unit.
- The HiiROC technology is being developed on the other side of the Humber in Hull.
- HiiROC technology captures the carbon in the gas as carbon black, which has uses in its own right, in agriculture and tyre and other manufacturing.
- Both a battery and a gas peaking plant, will be used at Brigg to match generation with demand.
I wouldn’t be surprised that to use both a battery and a gas peaking plant, is the most efficient way to balance the renewable energy.
Hydrogen Production
The HiiROC technology that will be used at Brigg can extract hydrogen from a variety of sources including biomethane, chemical plant off gas or natural gas.
The HiiROC technology can be scaled to fit the application.
I feel that the versatility of the HiiROC technology, may result in using some unusual feeds to produce hydrogen.
As an example of the deployment of a small HiiROC system , one at a sewage works could provide hydrogen for the utility company’s vehicles.
The main use of the hydrogen would be to provide a clean fuel for the gas-fired peaking plant.
I also wouldn’t be surprised to see the hydrogen, sold and distributed to the local area, from an energy park, like Brigg.
Conclusion
Increasingly, backup for renewables will use a wide range of zero-carbon technologies.
