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!
EDF Developing Offshore Wind-Powered Hydrogen Production Project In French EEZ
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
EDF Power Solutions has invited applications for a tender for Environmental Impact Assessment (EIA) services and hazard studies as part of a project to develop an offshore hydrogen production station in France’s Exclusive Economic Zone (EEZ).
This is the first paragraph.
The project, dubbed HYODE (HYdrogen Offshore DunkerquE), will produce green hydrogen by coupling offshore wind farms with an offshore electrolyser near Dunkirk, France, and is planned to also include storage and transport by ship to port, forming what EDF describes as an “innovative solution” to help scale green hydrogen production.
I asked Google AI, if there are any operational offshore hydrogen electrolysers and received this answer.
Yes, there are operational offshore electrolyser projects, though large-scale, dedicated offshore hydrogen platforms are still in development. The first operational offshore production on an existing gas platform is planned for late 2024 with the PosHYdon project. Additionally, a pilot project in the UK is testing the full integration of a hydrogen electrolyser onto an existing offshore wind turbine, with another project in the Netherlands installing an offshore hydrogen production and storage platform.
But, I did get this page on page on the Ramboll web site, which is entitled The Rise Of Offshore Hydrogen Production At Scale, which has this introductory paragraph.
The stage is set for producing green hydrogen from offshore wind and desalinated seawater. Building on existing and proven technology, offshore wind farms have the potential to become future production hubs for green hydrogen production at scale to meet increasing demand.
That sounds very promising, especially, if proven technology is borrowed from the offshore oil and gas industry.

UK, French, And Irish Ports Join Hands In Global Floating Wind Collaboration
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The UK’s Associated British Ports (ABP) has teamed up with France’s BrestPort and Ireland’s Shannon Foynes Port to establish the Global Floating Offshore Wind Ports Alliance (FLOW Ports Alliance) to help bring together major floating offshore wind ports across the world and unlock the technology’s full potential.
These first two paragraphs add more detail.
The FLOW Ports Alliance aims to recruit ports in Europe to collaborate on FLOW port design, standardisation, and best operational practices.
It plans to strengthen and accelerate compliant knowledge and experience exchange between ports, share best practices as they emerge through demonstration projects, and share innovations to the benefit of the global FLOW network.
Surely, a global network of ports that can handle construction, operation and maintenance of a range of floating wind platforms, is an excellent idea.
ENGIE And CDPQ To Invest Up To £1bn In UK Pumped Storage Hydro Assets
The title of this post, is the same as a news item from ENGIE.
These four bullet points act as sub-headings.
- Refurbishment programme to extend life of plants at Dinorwig and Ffestiniog will ensure the UK’s security of supply and support the transition to a low carbon energy future
- ENGIE owns 75% of the plants via First Hydro Company, a 75:25 joint venture with Canadian investment group CDPQ
- The two pumped storage hydro plants are the UK’s leading provider of power storage and flexibility, with 2.1GW of installed capacity
- They represent 5% of the UK’s total installed power generation capacity and 74% of the UK’s pumped storage hydro capacity
These three paragraphs give more details.
The preparation of a 10-year project of refurbishment at *ENGIE’s Dinorwig pumped storage station has begun, following an 8-year refurbishment at Ffestiniog, enabling the delivery of clean energy whenever needed.
These flexible generation assets, based in North Wales, are essential to the UK Government’s accelerated target of achieving a net zero carbon power grid by 2030. Together they help keep the national electricity system balanced, offering instant system flexibility at short notice. The plants are reaching end of life and replanting will ensure clean energy can continue to flow into the next few decades.
Re-planting could see the complete refurbishment of up to all six generating units at Dinorwig – a final investment decision is still to be made on the number of units to replace – while the re-planting at Ffestiniog will be completed at the end of 2025. The program also involves the replacement of main inlet valves – with full drain down of the stations – and detailed inspections of the water shafts.
It also looks like the complete refurbishment at Dinorwig will take ten years, as it seems they want to keep as much of the capacity available as possible.
When the replanting is complete, the two power plants will be good for twenty-five years.
Hopefully, by the time Dinorwig has been replanted, some of the next generation of pumped storage hydroelectric power stations are nearing completion.
The news item says this about Dinorwig.
Dinorwig, the largest and fastest-acting pumped storage station in Europe, followed in 1984 and was regarded as one of the world’s most imaginative engineering and environmental projects.
Dinorwig must be good, if a French company uses those words about British engineering of the 1980s.
DESNZ Launches Call For Evidence For Solar Carports In The UK
The title of this post is the same as this article on Solar Power Portal.
These three paragraphs introduce the article.
The UK Department for Energy Security and Net Zero (DESNZ) has launched a call for evidence to help increase the number of solar-powered carports in England, Wales, and Northern Ireland.
The likely result of this will be a mandate that car parks have a solar PV installation, as has been the case in France for some time.
Mandating solar on car parks has multiple benefits, which DESNZ is keen to emphasise. It says that a mandate would be a “better deal for motorists and businesses”
I may not be a fan of electric cars, but I’m certainly no fan of spreading solar panels over large areas of quality farmland.
There are some interesting statements.
Take this one.
DESNZ cites estimates that supermarkets, retail parks and offices could save up to £28,000 annually by installing solar carports (this figure calculated for an 80-space car park—the size that France mandates must be covered by solar PV) if all of the electricity generated by the solar array was used onsite.
£28,000 a year is not to be sneezed at!
And this one.
Earlier this year, Norwich-based RenEnergy, a solar carport provider, revealed that installing solar carports in more than half a million suitable parking spaces owned by UK businesses could generate 1.57GW of solar energy.
They do suggest that this figure only scratches the surface.
And then there’s this story from Bentley.
In 2019, Bentley Motors installed a solar car park at its headquarters in Crewe. The site’s 10,000 solar PV modules have a capacity of 2.7MW and cover an area of 16,426m². Along with other installed solar arrays and 6.6MW of battery energy storage, the car park enables all of Bentley’s manufacturing operations to be powered by solar or certified green energy.
How many other businesses could do that?
This Google Map shows the Bentley Motors site at Crewe.
Note.
- It appears to be a large site.
- Bentley employs over 4,000 employees at Crewe.
- In 2023, Bentley delivered 13, 560 cars.
- The solar car ports appear to be at the Western end of the site.
- There would appear to be a lot of scope to add more solar car ports at the Eastern end of the site.
Running along the Southern edge of the site is the North Wales Coast Line, which runs between Crewe and Chester and then on to North Wales.
I would have thought, that a case could be made out to have a station at the Bentley site for employees and visitors.
There also doesn’t seem to be the infrastructure, so that cars to some destinations can be delivered by train, like these from Toyota, which I photographed at Denmark Hill station, which were on the way to Europe, through the Channel Tunnel.
Perhaps sending luxury cars to their future owners by train is the wrong image.
France’s First And Only Operational Floating Wind Turbine Gets Lifetime Extension
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Floatgen, the demonstration floating wind turbine installed at the SEM-REV offshore test site in France, has completed its planned five-year run but will operate for another five years as the demo project was decided to get a lifetime extension.
These are the first three paragraphs.
The floater, which consists of a 2 MW Vestas V80 wind turbine mounted on BW Ideol’s Damping Pool foundation, reached electricity production milestones several times since going into full operation in September 2018.
According to BW Ideol, Floatgen’s cumulated production has now surpassed 30 GWh, which the company ascribes to “the hydrodynamic properties and excellent sea-keeping capabilities” of its floating foundation.
Floatgen’s availability averaged 92.18 per cent between January 2021 and January 2024, with December 2023 standing out with a monthly production record of 922.026 MWh and a 61.96 per cent capacity factor, BW Ideol says.
Note.
- A three-year availability average of 92.18 % is surely very good.
- A 61.96 % capacity factor is better than most other floating wind farms, which are generally in the fifties.
With those figures, I suspect BW Ideol will be expecting, some orders soon.
This video shows a Floatgen being constructed.
Europe Installs Record-Breaking 4.2 GW Of Offshore Wind In 2023
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Europe’s offshore wind industry brought online a record 4.2 GW of new capacity in 2023 and is expected to build around 5 GW of offshore wind annually over the next three years, according to WindEurope data. However, this is still not enough to meet the continent’s 2030 climate and energy security targets, WindEurope added.
These are the first two paragraphs.
The overall offshore wind capacity installed in 2023 was 40 per cent higher than in 2022. Of the 4.2 GW of new capacity, 3 GW was in the EU, an increase of 2.1 GW year on year, WindEurope said.
The Netherlands, France, and the UK installed the most new capacity, including the 1.5 GW Hollandse Kust Zuid offshore wind project in the Netherlands, according to the organisation.
But where are the Germans?
They’ve got plenty of steel and sea, Siemens make a lot of wind turbines and they certainly need the electricity.
In 2023, Germany generated their electricity as follows.
- Brown coal (17.7%)
- Hard coal (8.3%)
- Natural gas (10.5%)
- Wind (32.0%)
- Solar (12.2%)
- Biomass (9.7%)
- Nuclear (1.5%)
- Hydro (4.5%)
- Oil (0.7%)
- Other (2.9%)
By comparison the UK’s figures were.
- Coal (1%)
- Natural gas (32%)
- Wind (29.4%)
- Solar (4.9%)
- Biomass (5%)
- Nuclear (14.2%)
- Hydro (1.8%)
- Storage (1%)
- Imports (10.7%)
Note.
- The Germans use a lot of coal.
- The UK uses a lot more natural gas.
- Despite the much-criticised Drax, the Germans use twice as much biomass as we do.
- The UK uses tens times more nuclear.
The Wikipedia entries for German and UK wind power make interesting reading.
1 GW Wind Farm Proposed Offshore Jersey
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Jersey’s Council of Ministers has proposed to build a 1 GW offshore wind farm in the southwest of the island’s territorial waters that would produce enough electricity to meet its needs, with the remainder to be exported.
This first paragraph gives more details.
It is proposed that the offshore wind farm should be privately funded and designed, and delivered by a consortium with substantial experience of similar development elsewhere, according to the government.
I would have thought that Jersey would have been one of those places, that would have been too conservative for offshore wind.
But then, this is the last paragraph of the article.
In a 2019 Island Plan consultation, 85 per cent of respondents agreed or strongly agreed the plan should continue to encourage the development of offshore wind and tidal energy, according to the government.
But as the wind farm will export the surplus surplus, it could be a nice little earner.
This Google Map shows the Channel Islands.
This article on the BBC is entitled Islands Could Work Together On Wind Farm Plans.
These three bullet points sum up the article.
-
Guernsey and Jersey may work together to create a wind farm
-
Both States are hoping to create the wind farm off Jersey’s south-west coast
-
It could generate enough energy for both islands.
This looks like a sound way to reap the wind!
Teen’s Killing Raises A French Policing Issue That Dare Not Be Named
The title of this post, is the same as that of this article on France24.
This is the sub-heading.
The killing of 17-year-old Nahel M. during a police traffic stop this week was a depressingly familiar addition to France’s list of police brutality cases. But when the UN called on the government to address racial discrimination in its police force, the official reaction was just as familiar and depressing for France’s minorities.
These are the first five paragraphs.
On Friday, just a few days after a French police officer shot dead a teenager during a traffic stop in a Paris suburb, the UN Human Rights Office urged France to tackle racial discrimination.
“We are concerned by the killing of a 17-year-old of North African descent by police in France,” UN human rights office spokeswoman Ravina Shamdasani told a press briefing in Geneva.
“This is a moment for the country to seriously address the deep issues of racism and discrimination in law enforcement,” she added.
Shamdasani’s comments echoed innumerable statements released over the past few years by international rights groups, such as Amnesty International and Human Rights Watch, calling on the French state to address “systematic discrimination” particularly “the use of ethnic profiling” during identity checks.
If the UN human rights office believed the police killing of the teenager of Algerian descent, named Nahel M., could be the “moment” for an official French reckoning, it proved to be mistaken.
These are a few choice paragraphs.
Many Cases
Nahel’s killing in the western Paris suburb of Nanterre was the latest in a string of cases of police violence in France’s deprived, multi-ethnic banlieues, or suburbs. These include high-profile cases, such as the 2005 deaths of two young men in Clichy-sous-Bois, a Paris suburb, and the 2016 death of Adama Traoré in Val d’Oise, a banlieue further north. The victims were all non-white young males.
France And America
“Of course France and America are very different countries, but they have a common enemy: racism,” a demonstrator told FRANCE 24 at a June 2020 “Justice for Adama Traoré” protest. “Nothing will ever change until people are educated about racism. Starting with the police.”
One Bad Apple, Not The Orchard
Several French officials and security experts conceded that the video footage appeared to show the policeman acting in breach of procedures. But they insist it’s a case of one bad apple, not a rot in the orchard.
French Police And Military Voting
A July 2019 study by the left-leaning Fondation Jean-Jaurès found that more than 50% of French military and law enforcement personnel said they voted for far-right politician Marine Le Pen’s party in recent elections.
In the first round of the 2022 presidential election, 39% of police and military personnel voted for Le Pen while 25% voted for another far-right candidate, Éric Zemmour, according to polling institute Cluster17.
France Police Union Tweet
“Congratulations to the colleagues who opened fire on a young 17-year-old criminal. By neutralising his vehicle, they protected their lives and those of other drivers. The only ones responsible for this thug’s death are his parents, who were incapable of educating their son,” it read.
France’s “Licence To Shoot” Law
The law, which was passed following a spate of terror attacks in France, has been slammed as a “licence to shoot” legislation. In 2022 alone, 13 people were shot and killed by police in cases of non-compliance. While French authorities have not released the racial or ethnic identities of the victims, sociologist Sebastien Roche told a local French daily that there was an “overrepresentation of ethnic minorities among those killed during refusals to obey” police traffic stops.
The article is worth a full read.
Run Larger, Multi-Site Offshore Wind Tenders, French Energy Commission Recommends To Gov’t
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The French Energy Regulatory Commission (CRE) has recommended that the government conducts larger offshore wind tenders, inviting bids for several sites. This is according to the latest update from CRE, which has now published specifications for the country’s AO5 tender for a floating wind farm in southern Brittany.
Looking at the building of large numbers of wind turbines and their fixed or floating foundations, I am drawn to the conclusion, that it might be better if all were as identical as possible.
I should also note, that we were very successful selling Artemis project management systems in France. Our manager in the country, said it was because all the country’s top managers had been to the same schools and universities and passed the best solutions around themselves.
So perhaps a standard solution appeals to the French psyche?
In the UK, BP are currently designing and planning these fixed foundation wind farms.
- Mona – 1500 MW – 35 m. depth – 30 km. offshore
- Morgan – 1500 MW – 35 m. depth – 30 km. offshore
- Morven – 2907 MW – 65-75 m. depth – 60 km. offshore
Given that Mona and Morgan are in the Irish Sea and Morven is North-East of Aberdeen, I wouldn’t be surprised to find that BP treat these three projects as two separate 3 GW projects, which could share the same turbine design and fixed foundation designs, that were very similar.
I’m sure BP would save money, if they used a similar design philosophy on all three projects.
