Battery Trains Ordered For Hermann-Hesse-Bahn
The title of this post, is the same as that, of this article on Railway Gazette.
This article is yet another endorsement of battery-electric trains.
There is more about the history of the Hermann-Hesse-Bahn in Wikipedia entry for the Black Forest Railway.
Could the Germans be using a battery-electric railway to bring in the tourists?
UK National Grid In Talks To Build An Energy Island In The North Sea
The title of this post, is the same as that of this article on the New Scientist.
This is the first paragraph.
UK company National Grid has revealed it is in talks with two other parties about building an “energy island” in the North Sea that would use wind farms to supply clean electricity to millions of homes in north-west Europe.
These are my thoughts.
An Artificial Island on the Dogger Bank
The idea of the North Sea Wind Power Hub in the area of the Dogger Bank has been around for a few years and has a comprehensive Wikipedia entry.
Wikipedia says that it would be an artificial island on the Dutch section of the Dogger Bank and the surrounding sea could eventually host up to 110 GW of wind turbines.
North Sea Wind Power Hub Programme
The Dutch and the Danes seems to have moved on and there is now a web site for the North Sea Wind Power Hub Programme.
The home page is split into two, with the upper half entitled Beyond The Waves and saying.
The incredible story of how the Netherlands went beyond technical engineering as it had ever been seen before. Beyond water management. To secure the lives of millions of inhabitants.
I have met Dutch engineers, who designed and built the Delta Works after the North Sea Floods of 1953 and I have seen the works all over the country and it is an impressive legacy.
And the lower half of the home page is entitled North Sea Wind Power Hub and saying.
Today, climate policy is largely national, decoupled and incremental. We need a new approach to effectively realise the potential of the North Sea and reach the goals of the Paris Agreement. We take a different perspective: harnessing the power of the North Sea requires a transnational and cross-sector approach to take the step-change we need.
Behind each half are two videos, which explain the concept of the programme.
It is a strange web site in a way.
- It is written totally in English with English not American spelling.
- The project is backed by Energinet, Gasunie and TenneT, who are Danish and Dutch companies, that are responsible for gas and electricity distribution networks in Denmark, Ger,many and The Netherlands.
- There are four sections to the web site; Netherlands, Germany, Denmark and North Sea.
It is almost as if the web site has been designed for a British company to join the party.
Hubs And Spokes In North Sea Wind Power Hub Programme
If you watch the videos on the site, they will explain their concept of hubs and spokes, where not one but several energy islands or hubs will be connected by spokes or electricity cables and/or hydrogen pipelines to each other and the shore.
Many electrical networks on land are designed in a similar way, including in the UK, where we have clusters of power stations connected by the electricity grid.
The Dogger Bank
The Dogger Bank is a large sandbank in a shallow area of the North Sea about 100 kilometres off the east coast of England.
Wikipedia says this about the geography of the Dogger Bank.
The bank extends over about 17,600 square kilometres (6,800 sq mi), and is about 260 by 100 kilometres (160 by 60 mi) in extent. The water depth ranges from 15 to 36 metres (50 to 120 ft), about 20 metres (65 ft) shallower than the surrounding sea.
As there are Gunfleet Sands Wind Farm and Scroby Sands Wind Farm and others, on sandbanks in the North Sea, it would appear that the engineering of building wind farms on sandbanks in the North Sea is well understood.
The Dogger Bank Wind Farm
We are already developing the four section Dogger Bank Wind Farm in our portion of the Dogger Bank and these could generate up to 4.8 GW by 2025.
The Dogger Bank Wind Farm has its own web site, which greets you with this statement.
Building the World’s Largest Offshore Wind Farm
At 4.8 GW, it will be 45 % larger than Hinckley Point C nuclear power station, which is only 3.3 GW. So it is not small.
The three wind farms; Dogger Bank A, B and C will occupy 1670 square kilometres and generate a total of 3.6 GW or 0.0021 GW per square kilometre.
If this density of wind turbines could be erected all over the Dogger Bank, we could be looking at nearly 40 GW of capacity in the middle of the North Sea.
Interconnectors Across The North Sea
This Google Map shows the onshore route of the cable from the Dogger Bank Wind Farm.
Note.
- Hull and the River Humber at the bottom of the map.
- The red arrow which marks Creyke Beck sub station, where the cable from the Dogger Bank Wind Farm connects to the UK electricity grid.
- At the top of the map on the coast is the village of Ulrome, where the cable comes ashore.
The sub station is also close to the Hull and Scarborough Line, so would be ideal to feed any electrification erected.
I would assume that cables from the Dogger Bank Wind Farm could also link the Wind Farm to the proposed Dutch/Danish North Sea Wind Power Hub.
Given that the cables between the wind farms and Creyke Beck could in future handle at least 4.8 GW and the cables from the North Sea Wind Power Hub to mainland Europe would probably be larger, it looks like there could be a very high capacity interconnector between Yorkshire and Denmark, Germany and The Netherlands.
It almost makes the recently-opened North Sea Link to Norway, which is rated at 1.4 GW seem a bit small.
The North Sea Link
The North Sea Link is a joint project between Statnett and National Grid, which cost €2 billion and appears to have been delivered as planned, when it started operating in October 2021.
So it would appear that National Grid have shown themselves capable of delivering their end of a complex interconnector project.
Project Orion And The Shetlands
In Do BP And The Germans Have A Cunning Plan For European Energy Domination?, I introduced Project Orion, which is an electrification and hydrogen hub and clean energy project in the Shetland Islands.
The project’s scope is described in this graphic.
Note that Project Orion now has its own web site.
- Could the Shetlands become an onshore hub for the North Sea Power Hub Programme?
- Could Icelink, which is an interconnector to Iceland be incorporated?
With all this renewable energy and hydrogen, I believe that the Shetlands could become one of the most prosperous areas in Europe.
Funding The Wind Farms And Other Infrastructure In The North Sea
In World’s Largest Wind Farm Attracts Huge Backing From Insurance Giant, I described how Aviva were funding the Hornsea wind farm.
I very much believe that City of London financial institutions will be able to finance a lot of the developments in the North Sea.
After all National Grid managed to find a billion euros in a sock drawer to fund their half of the North Sea Link.
Electrifying The North Sea: A Gamechanger For Wind Power Production?
The title of this section, is the same as that of this article on Engineering and Technology Magazine.
This article in the magazine of the IET is a serious read and puts forward some useful facts and interesting ideas.
- The EU is targeting offshore wind at 60 GW by 2030 and 300 GW by 2050.
- The UK is targeting offshore wind at 40 GW by 2030.
- The article explains why HVDC electricity links should be used.
- The major players in European offshore wind are the UK, Belgium, the Netherlands, Germany, and Denmark.
- The foundations for a North Sea grid, which could also support the wider ambitions for a European super-grid, are already forming.
- A North Sea grid needs co-operation between governments and technology vendors. as well as technological innovation.
- National Grid are thinking hard about HVDC electrical networks.
- By combining HVDC links it can be possible to save a lot of development capital.
- The Danes are already building artificial islands eighty kilometres offshore.
- Electrical sub-stations could be built on the sea-bed.
I can see that by 2050, the North Sea, South of a line between Hull and Esbjerg in Denmark will be full of wind turbines, which could generate around 300 GW.
Further Reading
There are various articles and web pages that cover the possibility of a grid in the North Sea.
- National Grid – Interconnectors
- The Guardian – National Grid In Talks Over Plan For Energy Island In North Sea
- The Times – National Grid Planning ‘Energy Island’ In North Sea
I shall add to these as required.
Conclusion
I am coming to the conclusion that National Grid will be joining the North Sea Wind Power Hub Programme.
- They certainly have the expertise and access to funding to build long cable links.
- The Dogger Bank wind farm would even be one of the hubs in the planned hub and spoke network covering the North Sea.
- Only a short connection would be needed to connect the Dogger Bank wind farm, to where the Dutch and Danes originally planned to build the first energy island.
- There may be other possibilities for wind farm hubs in the UK section of the North Sea. Hornsea Wind Farm, which could be well upwards of 5 GW is surely a possibility.
- Would it also give access to the massive amounts of energy storage in the Norwegian mountains, through the North Sea Link or Nord.Link between Norway and Germany.
Without doubt, I know as a Control Engineer, that the more hubs and spokes in a network, the more stable it will be.
So is National Grid’s main reason to join is to stabilise the UK electricity grid? And in turn, this will stabilise the Danish and Dutch grids.
Namibia Is Building A Reputation For The Cheapest Green Hydrogen
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This paragraph explains the deal that Germany and Namibia have done.
Germany, the largest economy in Europe, has just closed a partnership with Namibia, for a supply of the cheapest green hydrogen. The Southern African country is aiming to produce its H2, made with renewable energy, for prices as low as $1.8/kg. The European nation intends to import massive volumes of what it believes will be the most affordable renewable H2 in the world. It has signed a deal with Namibia that steps up the worldwide scramble to secure the best options for H2 supply connected with substantial renewable installations.
Note.
- Namibia has the ability to produce large amounts of solar and wind energy.
- I suspect the hydrogen will be converted to liquid ammonia for shipment to Germany.
The Gremans are building a large hydrogen terminal at Wilhelmshaven, which I wrote about in Uniper To Make Wilhelmshaven German Hub For Green Hydrogen; Green Ammonia Import Terminal.
Although, Namibia has now been an independent country since 1990, from 1884 to 1915 it was the German colony of German South West Africa.
Hopefully, this deal will work out to the benefit of both Germany and Namibia.
Stadler FLIRT Akku Battery Train Demonstrates 185km Range
The title of this post, is the same as that of this article on Railway-News.
This is the first paragraph.
Stadler’s offering in the battery-powered rolling stock market, the FLIRT Akku has demonstrated a guaranteed range of 185km, even in energy-intensive conditions, it has been found following a three-year research period.
The range is very good and is over twice what Hitachi are claiming with the Hitachi Regional Battery Train.
I can’t find out many details of the size of a Flirt Akku train, but this article on the International Railway Journal has these details.
- A picture shows a three-car train.
- The trains have a 100 mph operating speed.
- Fifty-five two-car trains are on order for Schleswig-Holstein.
Stadler can also fit batteries into trains like Greater Anglia’s Class 755 trains.
There have been reports of these trains being fitted with batteries in a couple of years to reduce carbon emissions.
CAF Selected For Major Battery Train Order
The title of this post, is the same as that of this article on Railway Gazette International.
This is the first paragraph.
CAF has been named as preferred bidder for what it says is the largest order to date for battery trains. This covers the supply and maintenance of more than 60 electric multiple-units which will be able to operate on non-electrified sections of the Niederrhein-Münsterland network.
On reading the rest of the article, it sounds like the trains are to a high standard, with all the features one could expect.
As in Bolton-Wigan £78m Rail Electrification Project Announced, I predicted that CAF could sell a number of battery-electric trains to Northern in the UK, it looks like CAF could be building a substantial number of battery-electric trains.
There could even be the possibility of some of the German trains being assembled in the CAF factory in Newport, as the logistics might be easier.
Alstom’s Coradia iLint Hydrogen Train Makes Its Swedish Debut
The title of this post, is the same as that of this article on Global Railway Review.
This picture shows a hydrogen-powered Alstom Coradia iLint train near Hamburg
If you’re ever in Hamburg, take a ride to Buxtehude and take a ride to Cuxhaven.
These trains are now in service in Germany and have been ordered in quantity in Germany and have been demonstrated in Austria, Italy and The Netherlands.
Fraunhofer Targets Hydrogen Adoption With Improved Electrolysis System Efficiency
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This is the first paragraph.
The Fraunhofer Heinrich Hertz Institute (HHI) has announced that it is taking part in a new research project meant to accelerate hydrogen adoption. Its main focus is to examine water electrolysis in order to achieve improve efficiency.
The research project is called InnoEly, and this appears to be the project’s aim, as stated on the web site.
Modeling and characterization tools for the development of water electrolysers – from materials to system integration
This could be a project, that brings about a big improvement in the efficiency of electrolysers.
Shell Starts Up Europe’s Largest PEM Green Hydrogen Electrolyser
The title of this post, is the same as that of this press release from Refhyne.
These are the first three paragraphs.
Europe’s largest PEM hydrogen electrolyser*, today began operations at Shell’s Energy and Chemicals Park Rheinland, producing green hydrogen.
As part of the Refhyne European consortium and with European Commission funding through the Fuel Cells and Hydrogen Joint Undertaking (FCH JU), the fully operational plant is the first to use this technology at such a large scale in a refinery.
Plans are under way to expand capacity of the electrolyser from 10 megawatts to 100 megawatts at the Rheinland site, near Cologne, where Shell also intends to produce sustainable aviation fuel (SAF) using renewable power and biomass in the future. A plant for liquefied renewable natural gas (bio-LNG) is also in development.
It certainly seems a comprehensive green development.
- It will be based on a massive 100 MW electrolyser.
- I estimate that the electrolyser will produce just under 45 tonnes of hydrogen per day.
As ITM Power is part of the Refhyne consortium, the electrolyser is being built in their factory in Sheffield.
This paragraph quotes Shell’s Downstream Director, Huibert Vigeveno .
“Shell wants to become a leading supplier of green hydrogen for industrial and transport customers in Germany,” he added. “We will be involved in the whole process — from power generation, using offshore wind, to hydrogen production and distribution across sectors. We want to be the partner of choice for our customers as we help them decarbonise.”
Shell certainly have green ambitions.
The German View On England’s Win
This article on Die Welt is Germany’s view of last night’s football
Could West Africa Become A Green Energy Powerhouse?
I ask this question, because I have just read this article on Hydrogen Fuel News, which is entitled Green Hydrogen Potential Causes Germany to court West African countries.
The article has this sub-title.
Nations in that part of Africa have the capacity to meet 1500 times Germany’s 2030 H2 demand.
That would appear to be a massive amount of hydrogen.
This extract from the article, talks about energy production.
Initial results for the 15 West African Economic Area (ECOAS) countries revealed that a massive three quarters of West African land is appropriate for wind turbines. Moreover, the electricity production from wind energy in the region costs about half the amount it would in Germany.
Additionally, solar power systems can also be economically operated on about one third of the West African region.
Add in a few large electrolysers and you have the hydrogen.
The hydrogen can be transported to Germany by tanker, either as hydrogen or ammonia.
The German strategy is to be underpinned by education, as this extract explains.
In support of developing West African green hydrogen production, a new master’s graduate program on clean H2 technology will begin in September. The purpose of the program will be to train local green hydrogen scientific specialists. The first three waves of the program are expected to train about 180 students attending four universities in Côte d’Ivoire, Togo, Senegal, and Niger.
Perhaps the Commonwealth should do something similar in West African countries like Gambia, Ghana, Nigeria and Sierra Leone.
After all many parts of Australia have very similar climate and population densities and probably energy generation potential to large parts of West Africa.
The Geographical Advantage
It should also be noted that geographically West Africa is close to Europe by ship.
There are no pinch points like the Suez Canal
As the European hydrogen gas network grows, the journey will get shorter.
Does anybody know how long it would take a tanker to go between say Accra in Ghana to Rotterdam?
Conclusion
I would see four main benefits coming to West Africa.
- Electricity for all.
- Employment to support the new industries.
- Hydrogen to power transport.
- The value of all those exports.
Hopefully, the standard of living of all those in West Africa would improve.
