French Companies Unite On Superconducting Cable Project For Distant Offshore Wind Farms
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Air Liquide, CentraleSupélec, ITP Interpipe, Nexans, and RTE have joined forces to develop a project that connects distant offshore wind farms to shore via a High Voltage Alternating Current (HVAC) superconducting transmission system.
This introductory paragraph adds some detail.
The SupraMarine demonstrator project will study the electrical connection between offshore wind farms and the coastline using High-Temperature Superconducting (HTS) cables. Cooled by liquid nitrogen, the cables are said to transport electricity with near-zero energy loss.
Note.
- No details of the target distances are indicated.
- There is a detailed exploratory diagram.
It is certainly an ambitious project, but I feel it could have substantial uses.
I have a few thoughts and questions.
Can Sodium Metal Be Used For High Voltage Electrical Underground Cables?
Google AI answers this question as follows.
Yes, sodium metal was investigated and used in trial runs for high-voltage underground electrical cables in the late 1960s and early 1970s, as a potentially cheaper and more flexible alternative to copper and aluminum. However, it is not in common use today due to safety concerns and unfavorable lifecycle economics compared to aluminum.
When I was at ICI around 1970, they were researching the use of sodium for high voltage power cables.
- ICI had access to large amount of sodium chloride in Cheshire.
- The sodium metal can be obtained by electrolysis.
- Renewable electricity for electrolysis will be plentiful.
- Someone told me that their prototype cable was a polythene pipe with Sodium metal in the middle.
- I’ve read somewhere that sodium cables have interesting safe overload properties.
- I can understand the safety concerns and unfavorable lifecycle economics, especially where water is concerned.
Perhaps, French technology has improved in the sixty years?
Will Sodium Metal Be Used In The French Superconducting Cable?
Nothing has been disclosed!
But the office chat at ICI from those, who knew their sodium and their polythene, as they’d been working at ICI Mond Division for decades, was of the opinion that sodium/polythene cables were possible!
From The Diagram, It Looks Like Power Is Needed At Both Ends Of The Superconducting Cable
The diagram shows wind turbines at one end and the grid at the other end of the cable.
So will a battery or some other form of stabilisation be needed for when the wind isn’t blowing?
Will The French Superconducting Cable Have A High Capacity?
The basic capacity of a cable depends on three properties.
- The resistance of the cable.
- The cross-section area of the cable.
- The design of the cable must also be able too conduct away the heat generated by electricity flowing through.
Will The Technology Work For Interconnectors?
I don’t see why not!
DeepForm
On Wednesday I went to the TDAP Wave 8 Demo Day, which was organised by the Advanced Propulsion Centre.
One of the cohort of companies there was DeepForm, who were described like this.
DeepForm is transforming sheet metal pressing with its patented cold-shear press design, which reduces blank sizes by up to 45 % and trimming waste by up to 85%. This drop-in technology lowers material costs and embodied CO2 in existing press lines without compromising performance, quality or speed. Spun out of the University of Cambridge in 2022, DeepForm enables OEMs and Tier 1 suppliers to adopt the breakthrough through IP licensing, simulation and design support.
The company have an impressive web site, which deserves a very full read.
In their presentation, they showed two products, that could benefit from their innovation; a large steel component for Jaguar Land Rover and a humble aluminium drink can.
As I walked home ntoday, I saw this advert displayed on a bus stop.
The cans for BuzzBallz are also shown on the company’s web site.
But these products are are only the start.
For instance, I can see lots of small plastic items and components, that can’t be recycled, could be made from aluminium, which is easy to be recycle.
I also think companies like IKEA will love the design freedom, the technology will give.
UK Offshore Wind Farm Now Equipped With Scour Protection Doubling As Marine Life Habitat
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
RWE has installed around 75,000 reef cubes developed by the nature-inclusive technology designer ARC marine at the Rampion offshore wind farm in the UK, in what the Rampion owner says is a “global first”. The cubes are a specially eco-engineered scour protection solution for wind turbine foundations, and this represents their first full-scale deployment at an offshore wind farm.
These four paragraphs add more details.
The solution is designed to protect the energy infrastructure from strong currents in the subsea environment, while creating new and extending existing living marine habitats, RWE says.
The reef cubes, ranging in size from 15 to 35 centimetres, were installed over the last few days at the base of one of the Rampion turbines by the project’s contractor Rohde Nielsen. It is the first real-world deployment of ARC marine’s patented Reef cubes as scour protection at an operational wind farm, according to RWE.
The developer says that at just one of the Rampion turbines, the reef cubes are providing a habitat surface area of 25,000 square metres.
The deployment is part of the Reef Enhancement for Scour Protection (RESP) pilot that RWE and ARC marine announced in July this year.
ARC marine’s reef cubes have their own comprehensive web site, which show all aspects of this fascinating technology.
Unlocking Efficiency With Cryogenic Cooling Of GaN Traction Inverters
The title of this post, is the same as this insight on the Ricardo web site.
This is the introduction.
As the mobility sector accelerates toward zero-carbon propulsion, hydrogen fuel cell systems (HFCS) are emerging as a cornerstone technology for aviation, marine, and long-haul road transport. Among the most promising innovations in this space is the use of liquid hydrogen (LH₂) not only as a fuel source but also as a cryogenic coolant for electric powertrains. This dual-purpose approach offers transformative potential in system efficiency, packaging, and weight reduction—especially when paired with Gallium Nitride (GaN) semiconductors.
It is a very simple concept, but it appears to give worthwhile efficiency gains.
This was the article’s conclusion.
Ricardo’s cryogenic GaN inverter concept represents a bold leap toward ultra-efficient, lightweight, and integrated hydrogen propulsion systems. While challenges remain in materials, packaging, and reliability, the experimental results are compelling. With efficiencies nearing 99.8% and mass reductions over 50%, cryogenic cooling could redefine the future of electric mobility.
As the hydrogen economy matures, innovations like this will be pivotal in delivering clean, scalable, and high-performance solutions across all mobility sectors.
I very much suggest, that you take the time to read the whole insight.
Using The Concept In a Liquid Hydrogen Carrier
This Wikipedia entry describes the design and operation of an ocean-going liquid hydrogen carrier.
This is a paragraph.
Similar to an LNG carrier the boil off gas can be used for propulsion of the ship.
Ricardo’s concept would appear to be advantageous in the design of liquid hydrogen carriers and I would expect, it could also be applied to the design of LNG carriers.
I would not be surprised to see liquid hydrogen and LNG carriers were the first application of Ricardo’s concept.
This Wikipedia entry describes the Suiso Frontier, which is the world’s only liquid hydrogen carrier.
I believe that Ricardo’s concept could lead to the construction of a more of these ships. Will they mean that liquid hydrogen carriers will deliver hydrogen from sunny climes to places like Europe, Japan, Korea and Canada.
The concept would also enable efficient small liquid hydrogen carriers, that could deliver hydrogen on routes like the North of Scotland to Germany.
Using The Concept In A Railway Locomotive
I could see freight locomotives being designed as a large liquid hydrogen tank with appropriately-sized fuel cells and added electrical gubbins.
- They would be self-powered and would not require any electrification.
- They would be much quieter than current diesels.
- They could pull the heaviest freight trains, between Europe and Asia.
- They could even pull passenger trains, if an electrical hotel supply were to be arranged.
- They could be designed with very long ranges.
But above all they would be zero-carbon.
Note that I’ve written about long freight routes before.
- China, Russia And The EU’s Intermarium Bloc
- How To Move 100,000 Containers A Year Between Germany And China
- Georgia, Azerbaijan and Iran Discuss New Freight Corridor To link India And Europe
- Finland And Norway To Explore Building Arctic Rail Link
- A New Gateway To China: Europe Prepares For The Launch Of Baku–Tbilisi–Kars Railway
I believe that a long-distance liquid-hydrogen locomotive, that was based on the Ricardo concept, would be ideal for some of these routes.
A Specialised Hydrogen Delivery Train
In April 2022, I wrote The TruckTrain, where this is a simple description of the concept.
The Basic Design Concept
The leaflet on their web site describes the concept.
This visualisation at the bottom of the leaflet shows four TruckTrains forming a train carrying twelve intermodal containers, each of which I suspect are 20 feet long.
I believe that the TruckTrain concept could be converted into a hydrogen delivery train.
- It would be an appropriate length.
- It would be powered by the on-board hydrogen.
- The hydrogen would be stored as liquid hydrogen.
It would be able to go most places on the UK rail network.
Conclusion
Ricardo’s concept could revolutionise the use of hydrogen.
South Eastern Railway Deploys IsoMat Thermal Technology To Keep Trains On The Tonbridge To Hastings Line Running In Hot Weather
The title of this post, is the same as that of this news item on the Network Rail web site.
This is the sub-heading.
A new type of technology is being trialled on the Tonbridge to Hastings railway line to help keep trains running in hotter weather, and more reliable journeys for passengers and freight customers.
These two paragraphs add more details.
The South Eastern Railway has partnered with UK green tech start-up Flint Engineering to combat excessive heat in railway signalling cabinets that can exceed 70°C, with a new patented system that requires no power, maintenance, or internal cabinet modifications, and can be installed in under an hour.
Flint’s innovative IsoMat technology delivers peak temperature reductions of over 21%, on the hottest days, transferring thermal energy thousands of times more efficiently than copper or aluminium alone.
This is one of those ideas, that could be filed under Too Good To Be True.
This picture shows the device in operation.
I can see this device having many uses, in the most surprising places.
Demonstration Of Commercial-Size Hydrogen Module
The title of this post, is the same as that of news item on the SunHydrogen web site.
This is the sub-heading.
SunHydrogen has successfully demonstrated live operation of its commercial-size 1.92m² hydrogen module, producing renewable hydrogen using only sunlight and water. This major milestone showcases the scalability and off-grid potential of the company’s renewable hydrogen production technology.
These first three paragraphs add more details.
SunHydrogen, developer of a breakthrough technology to produce renewable hydrogen using sunlight and water, today announced the successful live operation of its 1.92 m² (20.7 sq. ft.) hydrogen module. Conducted in an open prototype housing, the demonstration marks a pivotal milestone in the company’s path toward commercial-scale, renewable hydrogen production.
The 1.92m² hydrogen module, which uses only sunlight and water to produce hydrogen, represents the most advanced version of SunHydrogen’s proprietary hydrogen production technology. Engineered to operate independent of the electrical grid, the system integrates solar collection and hydrogen production into a single unit, offering a modular and scalable solution for distributed renewable hydrogen.
“This successful demonstration of the commercial-size reactor underscores the progress we’ve made in bringing our technology out of the lab and into the real world,” said Tim Young, CEO of SunHydrogen.
There is a video of this demonstration.
On their home page, there is a section called A Breakthrough In Clean Energy, where this is said.
SunHydrogen has developed a breakthrough technology to produce renewable hydrogen using sunlight and any source of water.
By optimizing the science of water electrolysis at the nano-level, our low-cost photoelectrochemical technology uses sunlight to separate hydrogen from water, making the process truly green from start to finish.
I will accept their word that it is truly green, but it is truly unique in that it doesn’t appear to use only sunlight to generate hydrogen.
Singapore’s First Hydrogen-Powered Data Center Launched By DayOne Using SOFC Technology
The title of this post, is the same as that of this article on Fuel Cell Works.
These two bullet points act as sub-headings.
- DayOne has broken ground on its first AI-ready hyperscale data center in Singapore, a 20MW facility set to be operational in 2026. The project integrates 100% renewable energy, SOFC-based hydrogen power generation, and cutting-edge hybrid cooling technologies.
- Strategic partnerships with Sembcorp and NUS will drive green energy adoption and R&D in sustainable tropical data center innovation, aligning with Singapore’s AI and digital infrastructure goals.
This data centre and the companies and the technologies behind it, are certainly ones to watch.
The R & D and innovation behind it could allow data centres to be built in more tropical places than is currently possible.
National Grid Pioneers UK-First Trial Of 3D Printed Technology For Low-Carbon Substations
The title of this post, is the same as that of this press release from National Grid.
These three bullet points act as sub-headings.
- Collaboration with Hyperion Robotics and the University of Sheffield will trial low-carbon 3D-printed concrete foundations including at National Grid’s Deeside Centre for Innovation in North Wales
- Innovation could reduce waste, carbon emissions and costs to consumers of network construction
- If rolled out across National Grid substations the technology could save up to 705 tons of concrete and 323 tons of CO2 and deliver £1.7 million in consumer savings versus traditional methods over a 10-year period
These two paragraphs give more details.
National Grid is working with Hyperion Robotics and the University of Sheffield on a UK-first trial to manufacture, install and test 3D-printed substation foundations, which have the potential to reduce construction-driven carbon emissions and reduce costs to consumers of network construction. This is part of National Grid’s commitment to leverage innovation to future-proof the network.
If the project is successful and the technology is rolled out across all National Grid substations, it is estimated it could save up to 705 tons of concrete and 323 tons of CO2 over a 10-year period, and deliver £1.7 million in consumer savings versus traditional methods.
The foundation design will deliver significant savings across the entire value chain.
- 70% reduction in concrete usage
- 80% less soil displacement
- 65% decrease in embodied carbon emissions
- 70% weight reduction compared to typical foundations
- 50% reduction in site operative hours, streamlining production
The foundations will be designed and produced in Finland by Hyperion Robotics, and tested at full-scale by the University of Sheffield. Further field testing will then be carried out at National Grid’s state-of-the-art testing facility, the Deeside Centre for Innovation in North Wales, later in 2025.
Conclusion
I like this technology and I suspect there are many other applications of 3D Concrete Printing.
Technology Behind Siemens Mobility’s British Battery Trains Hits The Tracks
This title of this post is the same as that of this news item from Siemens, which was published in December 2024.
These three bullet points introduce the news item.
- The Mireo Plus B battery train is rolled out in the East Brandenburg network, Germany, using the same technology as the British Desiro Verve project.
- The Desiro Verve would save £3.5 billion and 12 million tonnes in CO2 emissions for Britain’s railways over 35 years.
- The development marks the latest step of this technology’s journey to Britain’s railways.
No-one, including me, seemed to have spotted this news item, especially, since it is significant to both the UK and Germany.
But then parts of Siemens’s home country; Germany and Yorkshire, where they are building, a train factory to build London’s new Piccadilly Line trains have something big in common – There is a distinct shortage of electric trains and the overhead wires to power them.
So did German engineers, egged on by pints of British real ale, realise that their battery-electric technology for the Mireo Plus B battery-electric train, would turn a Desiro City multiple unit, like the Class 700, 707 or 717 into battery-electric trains.
These are three paragraphs from the Siemens news item.
The innovative technology behind Siemens Mobility’s British battery trains has been rolled out in the East Brandenburg network in Germany.
31 of the company’s Mireo Plus B trains are being phased in to the Berlin Brandenburg metropolitan region, beginning on Sunday (15 December) and is the latest proof point of the technology that underpins the Desiro Verve project in Britain. This follows the debut of this technology on 27 new trains in the Ortenau region of Germany in April, with more set to arrive in Denmark in 2025.
The British Desiro Verve trains would be assembled at Siemens Mobility’s new Train Manufacturing Facility in Goole, East Riding of Yorkshire, formally opened by the Transport Secretary and Mayor of London in October.
I’d always wondered, what Siemens would do with this factory, when it had finished making the Piccadilly Line trains.
It also should be noted, that the boss of Siemens UK, when the Goole factory was planned was Jürgen Maier, who according to his Wikipedia entry has Austrian, British and German citizenship and is now the boss of Great British Energy.
I believe that Siemens have big plans for the Goole factory.
One thing it has, that at the present time could be a problem in Germany, is large amounts of renewable electricity and hydrogen, so will energy-intensive components for trains be made at Goole?
It will be interesting to see how the Goole factory develops.
The Desiro Verve Train For The UK and Ireland
In the Siemens news item, their Joint CEO for the UK and Ireland; Sambit Banerjee, says this.
The Desiro Verve would be assembled at our state-of-the-art Goole Rail Village in Yorkshire and offers an integrated solution to replace Britain’s aging diesel trains without having to electrify hundreds of miles of track, saving the country £3.5 billion over 35 years and providing a practical path to decarbonising British railways.”
In June, Siemens Mobility identified how the Desiro Verve could save Britain’s railways £3.5 billion over 35 years compared with using diesel-battery-electric ‘tri-mode’ trains. This would support the Government’s aim of removing diesel-only trains from Britain’s railways by 2040.
The British trains would be powered by overhead wires on already electrified routes, then switch to battery power where there are no wires. That means only small sections of the routes and/or particular stations have to be electrified with overhead line equipment (OLE), making it much quicker and less disruptive to replace diesel trains compared to full electrification.
I agree with his philosophy.
The Rail Charging Converter
When I wrote Cameron Bridge Station – 15th May 2025, I described how a short length of overhead electrification could be erected at the station to charge passing trains, using their pantographs.
Cameron Bridge station is lucky in that there is already a 132,000 KVAC electricity connection to the distillery next door.
But at other places, where there is no connection, you could wait as long as seven years to be connected to the grid.
So Siemens have come up with the Rail Charging Converter, that provides a local electricity supply to support the charger.
It is described in this paragraph from the news item.
This OLE can also be installed much more quickly using Siemens Mobility’s innovative Rail Charging Converter (RCC), which makes it possible to plug directly into the domestic grid – potentially cutting delivery times for OLE from seven years to as little as 18 months.
This Siemens visualisation shows a Verve train and an RCC.
This arrangement could be used in sensitive countryside or close to historic buildings.
Modern Railways – June 2025
There is an article about the Siemens technology in the June 2025 Edition of Modern Railways.
It is called The Battery Revolution Starts In Long Marston for which this is part of the sub-heading.
New technology being installed by Siemens Mobility at Porterbrook’s test facility paves the way for widespread use of battery trains in the UK.
The article is a must-read.
Conclusion
Siemens appear to have the technology with their Rail Charging Converter and battery-electric trains like the Verve and the Mireo Plus B, to be able to decarbonise lines without electrification all over the world.
Would larger gauge trains be delivered from Germany and smaller gauge ones from Goole?
I wouldn’t be surprised that a version for a German S-Bahn could share more characteristics, with a small British train, than a large German one.
I can also see an underground railway, that was built without power in the tunnels. So if you were building the Waterloo and City Line today, would it be battery-electric and charged at each end of the line using a pantograph?
Surgeon Invents Plastic-Reducing Urine Collection Pot
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A hospital specialist has invented a new product that manages to reduce plastic and simplify the process of testing urine.
These three introductory paragraphs, add more detail.
Consultant urologist Dr Nick Burns-Cox has been working on his own innovation, the Pee-In-Pot (PiP) for 10 years.
Made from bamboo and sugar cane, it removes four items from the current urine collection process, three of them plastic.
Mr Burns-Cox, who works at Musgrove Park Hospital in Taunton, said he hoped it would cut down the use of single-use plastic in the NHS and reduce the chance of errors.
I like the design of this simple device.
But, personally, I hope it becomes universal, as I have trouble giving urine samples.
I had my stroke in Hong Kong and the Chinese nurses, were so aggressive, when it came to taking urine samples, they have given me an aversion to them.
In my view the device could help the patient psychologically, at what could be a difficult time.
