Good Energy’s Juliet Davenport Joins Gravitricity
The title of this post, is the same as that of this article on Solar Power Portal.
Taking the title of this article at face value, it is probably good practice for a company like Gravitricity to take on someone like Juliet Davenport, as they move to the next phase of their business.
The article also mentions Gravitricity’s developments in the storage of hydrogen and heat.
This paragraph also mentions a new development.
Gravitricity is now developing plans for a full-scale energy storage project at a recently closed coal mine in mainland Europe, in what will be the start of a pipeline of projects worldwide.
That does seem to be good news.
Note that it is recently closed coal mine. This is surely for the best, as who knows what the state of long-disused mine will be? My project management and engineering knowledge, says that an orderly handover can reduce the cost of the installation.
Could The Morocco-UK Power Project Be Developed Into A Western Europe And Africa Interconnector?
This page on the Xlinks web site, describes the Morocco-UK Power Project, which is proposed to generate solar and wind power in Morocco and deliver it to the UK.
- The plan envisages 10.5 GW of electricity being generated.
- There will be a 5GW/20GWh battery in Morocco.
- They will export 3.6 GW of electricity to the UK for at least twenty hours per day.
- The electricity will be exported to the UK by an Interconnector that skirts to the West of Spain, Portugal and France.
- The interconnector will be 3,800 kilometres long.
I described the project in detail in Moroccan Solar-Plus-Wind To Be Linked To GB In ‘Ground-Breaking’ Xlinks Project.
This Google Map shows Western Europe And North Africa.
Note.
- The light blue of the Continental Shelf
- The darker blue of deeper water.
- The Southern end of the Morocco and the UK interconnector will at Guelmim Oued Noun in the South of Morocco, which is indicated by the red arrow.
- The UK end of the cable will be at Alverdiscott between Barnstaple and Bideford in North Devon.
- Southern Morocco and Algeria look to be mainly in the Sahara Desert.
If we look at the route of the cable, it connects a lot of possible renewable energy sources.
- Morocco – Solar and wind
- Spain – Solar and wind
- Portugal – Solar and wind
- France – Nuclear, tidal and wind
- UK – Nuclear and wind.
Could the UK and Morocco interconnector be developed into a bigger power project?
- Solar and wind power from Algeria could be added.
- Tidal power from a Severn Barrage could be added.
- Connections could be added to Gibraltar, the Irish Republic and Wales.
I believe that there could be a large amount of electricity developed on the Western costs of Europe and Africa.
An interconnector would move it to where it is needed.
Quinbrook To Build The UKs Largest Consented Solar + Battery Storage Project
The title of this post, is the same as that article on Financial Buzz.
This is the first paragraph.
Quinbrook Infrastructure Partners (“Quinbrook”), a specialist global investment manager focused exclusively on renewables, storage and grid support infrastructure investment, today announced that it has acquired a consented 350MW Solar + Battery storage project, located in Kent, UK (“Project Fortress”). Quinbrook expects to commence construction of the project in the first half of 2022.
I have also read about Quinbrook on their web site.
A section on the site is entitled Our Industry Pedigree, where this is said.
Quinbrook is led and managed by a senior team of power industry professionals who have collectively invested over US$ 8.2 billion in energy infrastructure assets since the early 1990’s, representing over 19.5GW of power supply capacity. Our team brings an industrial perspective to investing in low carbon and renewables infrastructure.
Could companies like this be one of the keys to get more renewable power sources delivered?
How Clean Energy And Jobs Can Flow From Morocco to The UK
The title of this post, is the same as that of this article in The Times.
- The article has been written by Simon Morrish, who is the founder and CEO of Xlinks.
- The article is about his plans to build a 10.5 GW solar and wind power complex in Morocco and connect it to the UK, by an undersea power cable running up the coasts of Morocco, Spain, Portugal and France.
- This page on the Xlinks web site gives details of the project.
These are some points from the article.
Relationship With The Exchequer
He makes these points about the projects relationship with the Exchequer.
- The company will be a net contributor.
- The project will not require government subsidy of finance.
- Energy will be delivered under the Contract for Difference (CfD) price of £48/MWh.
- This compares with a CfD price of £92/MWh for Hinckley Point C.
Simon Morrish also claims they will be energised before Hinckley Point C.
That sounds good to me.
Finance
I wonder if at the CfD price quoted in the article, could this mean that this is a project that could be financed in the City of London or from a Sovereign Wealth Fund?
As Simon is confident the project can be completed before Hinckley Point C, I suspect that the finance might be in place, even if it hasn’t been signed off.
The 20GWh/5GW Battery
Simon says this about the battery.
Alongside the consistent output from its solar panels and wind turbines, a 20GWh/5GW battery facility will ensure power generated can be delivered every day, resulting in a dedicated, near-constant source of flexible and predictable renewable energy, designed to complement renewable energy generated in the UK.
In Moroccan Solar-Plus-Wind To Be Linked To GB In ‘Ground-Breaking’ Xlinks Project, I forecast that the battery would be from Highview Power, but given the delivery date before Hinckley Point C, I would suspect that Xlinks have a battery supplier in mind.
Employment Benefits
Simon says this about employment benefits.
Thousands of jobs will be created in Morocco and also at home.
If the project goes ahead, given its size, I don’t think many would disagree with that.
Simon also claims the project will create 1350 permanent jobs by 2024. Sites mentioned include Hunterston, Port Talbot and the North East of England.
Simon’s Conclusion
This is Simon’s conclusion about the project.
I love the idea of clean electricity flowing, all the way from Morocco to the UK. I hope it may inspire other ambitious renewable energy projects too — which, together, will provide clean, secure and stable energy, at affordable prices, for businesses and households to rely on and help to protect this special planet.
If you can, I suggest you read the full article on The Times.
Conclusion
The more I read about this project, the more I tilt towards it being feasble
Engineering is the science of the possible, whereas politics is dreads of the impossible.
Moroccan Solar-Plus-Wind To Be Linked To GB In ‘Ground-Breaking’ Xlinks Project
The title of this post, is the same as that of this article on Current News.
This is the first paragraph.
New solar and wind under development in Morocco is to be linked with Britain, with developer Xlinks also seeking to develop a cable manufacturing industry.
It looks to be a very challenging project.
- The HVDC cable will be 3,800 km long.
- The plan envisages 10.5 GW of electricity being generated.
- There will be a 5GW/20GWh battery in Morocco.
- They will export 3.6 GW of electricity to the UK for at least twenty hours per day.
- The electricity will be exported to the UK by a cable that skirts to the West of Spain, Portugal and France.
- The UK end of the cable will be at Alverdiscott in Devon.
All except the last are pushing current technology to the limit.
There is more information on the Morocco-UK Power Project page on the Xlinks web site.
- The company claims, that it can supply renewable energy, that acts like baseload power.
- When complete, it could supply eight percent of the UK’s energy needs.
These are my thoughts.
The 3,800 km. HVDC Link
This paragraph on the project web page describes the HVDC link.
Four cables, each 3,800km long form the twin 1.8GW HVDC subsea cable systems that will follow the shallow water route from the Moroccan site to a grid location in Great Britain, passing Spain, Portugal, and France.
It appears that would be 15200 kilometres of cable.
The longest HVDC link in the world is 2375 km. It’s overland and it’s in Brazil.
I can’t think otherwise, than that this will be a very challenging part of the project.
This Google map shows the area of Morocco, where the energy will be generated.
Note.
- Guelmim Oued Noun is outlined in red.
- The Canary Islands are just off the map to the West.
At least the project will be able to have convenient access to the sea.
This second Google Map shows the <Moroccan, Portuguese and Spanish coasts from Guelmim Oued Noun to the Bay of Biscay.

- There are other large cities on the route in Morocco, Portugal and Spain.
This third Google Map shows the Bay of Biscay.
Note.
- The light blue of the Continental Shelf

- There are a series of islands off the Spanish and French coasts.
- Could these islands be used as stepping stones for the cable?

Note.
- Bideford is in the North-West corner of the map.
- The red arrow indicates the Alverdiscott substation.
- The River Torridge runs through the town of Bideford.
Could the river be used to bring the cables from Morocco to the substation?
This seventh Google Map shows the Alverdiscott substation
Note the solar farm to the South of the substation.
HVDC Cable
The article also says that they may be building their own cable-manufacturing facility. Does this indicate that there is a shortage of HVDC cable?
Judging by the number of proposed interconnectors proposed for UK waters, it might be a prudent move to improve cable-manufacturing capacity.
10.5 GW Of Zero-Carbon Electricity
This sentence on the project web page describes the power generation.
This “first of a kind” project will generate 10.5GW of zero carbon electricity from the sun and wind to deliver 3.6GW of reliable energy for an average of 20+ hours a day.
It appears that they will be providing a baseload of 3.6 GW to the UK for over twenty hours per day.
Consider.
- Hinckley Point C has an output of 3.2 GW.
- As I write this around midnight, the UK is generating 22.2 GW of electricity.
This paragraph from their web site describes the advantages of Morocco.
Most importantly, Morocco benefits from ideal solar and wind resources, required to develop renewable projects that could guarantee suitable power production throughout the year. It has the third highest Global Horizontal Irradiance (GHI) in North Africa, which is 20% greater than Spain’s GHI and over twice that of the UK. Furthermore, the shortest winter day still offers more than 10 hours of sunlight. This helps in providing production profiles that address the needs of the UK power market, especially during periods of low offshore wind production.
It is not a small power station in the wrong place.
The 5GW/20GWh Battery
That is a massive battery.
The world’s largest lithium-ion battery is Gateway Energy Storage in California. It has a capacity of 250 megawatts for one hour.
The proposed battery in Morocco is eighty times as large.
If I was choosing a battery for this application, I believe the only one that has been demonstrated and might work is Highview Power’s CRYOBattery.
I wrote about Highview’s similar type of application to Morocco in Chile in The Power Of Solar With A Large Battery.
But that installation only will only have storage of half a GWh.
But I believe Highview and their partner; MAN Energy Solutions can do it.
Conclusion
I wish the company well, but I have a feeling that there’s a chance, that this will join the large pile of dead mega-projects.
But I do feel that the solar and wind power station in Morocco will be developed.
And like the project in Chile it will have a large Highview CRYOBattery.
Battersea Power Station From The South
I took these pictures of Battersea Power Station, as I walked back to Battersea Power Station station.
It seems to be coming on!
But will it all end it tears? It’s already bankrupted a couple of companies to get this far!
Could Drax Power Station Solve The Carbon Dioxide Shortage?
Drax Power station is the largest power station in the UK, with a 2.6 GW capacity when burning biomass.
It has also been a regular target of environmental activists complaining of the power station’s carbon dioxide and other emissions.
But could it be an unlikely saviour to replace the carbon dioxide that comes from two fertiliser plants run by the CF Industries, that have been shut down by high gas prices?
I wrote about the shortage in Food Shortages Looming After Factory Closures Hit Production.
Two and a half years ago I wrote Drax Becomes First Wood-Burning Power Plant To Capture Carbon, which was based on an article in the Financial Times.
I said this about the report.
This news has been treated in a more sensationalist way by other news media and sites, but the FT gives it very straight.
Drax power station is running an experiment, that removes a tonne of carbon dioxide a day.
But that is only the start of the process and most of it is released to the atmosphere.
They are currently, looking for profitable and environmentally-friendly ways of disposal, including selling it to beer manufacturers.
Didn’t we have a carbon-dioxide shortage a few months ago?
Now is probably a good time to dig a little deeper into what Drax is doing.
The Wikipedia entry for Drax power station has a section called Carbon Capture And Storage.
This is the last paragraph of the section.
In May 2018, Drax announced a new carbon capture and storage pilot scheme that it would undertake in conjunction with the Leeds-based firm, C-Capture. The focus of this pilot will be on capturing carbon post combustion from the biomass burners as opposed to the coal burners. Drax will invest £400,000 into the project. The company, C-Capture, is a side company of the Department of Chemistry established at the University of Leeds. This would yield about 1-tonne (1.1-ton) of CO2 stored per day from the process, which could be sold on for use in the drinks industry. The pilot scheme was launched in February 2019. The capture of carbon from biomas burners is known as Bio Energy with Carbon Capture and Storage (BECCS).
Who are C-Capture?
Their web site is very informative and this page is called Our Story, which explains the project at Drax.
We designed, built, and installed a pilot plant and have been operating it on site, with real flue gas, since early 2019. The data gathered from this trial is feeding directly into the design process for a full-scale plant, with a target of 10,000 tonnes of CO2 per day captured from one of Drax’s four biomass fired boilers. A recent development has been the installation of equipment to bottle the captured CO2 to allow other organisations to test their own developing technologies with genuine Drax derived CO2.
That looks like a result to me for C-Capture.
This page is called Technology and has a very neat interactive guide to how the technology works.
Conclusion
This company has some very special technology, that has a lot of applications.
It is also significant that Drax and BP have taken a shareholding in C-Capture.
Is Carbon Dioxide Not Totally Bad?
To listen to some environmentalists, there views on carbon dioxide are a bit like a variant of George Orwell’s famous phrase Four legs good, two legs bad from Animal Farm, with carbon dioxide the villain of the piece.
I have just read the Wikipedia entry for carbon dioxide.
For a start, we mustn’t forget how carbon dioxide, water and sunlight is converted by photosynthesis in plants and algae to carbohydrates, with oxygen given off as waste. Animals like us then breathe the oxygen in and breathe carbon dioxide out.
Various web sites give the following information.
- The average human breathes out 2.3 pounds of carbon dioxide per day.
- As of 2020, the world population was 7.8 billion.
This means humans breathe out 17.94 billion pounds of CO2 per day
This equates to 6548.1 billion pounds per year or 2.97 billion tonnes per year.
And I haven’t counted all the other animals like buffalo, cattle, elephants and rhinos, to name just a few large ones.
Wikipedia also lists some of the Applications of carbon dioxide.
- Precursor To Chemicals – Carbon dioxide can be one of the base chemicals used to make other important chemicals like urea and methanol.
- Foods – Carbon dioxide has applications in the food industry.
- Beverages – Carbon dioxide is the fizz in fizzy drinks.
- Winemaking – Carbon dioxide has specialist uses in winemaking.
- Stunning Animals – Carbon dioxide can be used to ‘stun’ animals before slaughter.
- Inert Gas – carbon dioxide has several uses, as it is an inert gas.
- Fire Extinguisher – Carbon dioxide is regularly used in fire extinguishers and fire protection systems.
- Bio Transformation Into Fuel – It has been proposed to convert carbon dioxide from power stations into biodiesel using a route based on algae.
- Refrigerant – Carbon dioxide can be used as a refrigerant. It was used before CFCs were developed and I know of a large Victorian refrigeration system on a farm in Suffolk, used on a store for apples, that still is in regular use that uses carbon dioxide.
- Dry Ice – The solid form of carbon dioxide has lots of applications, where cooling is needed.
Other important applications are under development.
- Agriculture – Carbon dioxide is piped to greenhouses to promote growth of crops. It is also used at higher concentrations to eliminate pests.
- Low Carbon Building Products – Companies like Mineral Carbonation International are developing ways of creating building products from carbon dioxide.
- Synthetic Rubber – Research is ongoing to create replacements for synthetic rubber.
I can only assume, that the demand for gaseous carbon dioxide will increase, as scientists and engineers get more innovative about using the gas.
Solving A Shortage Of Carbon Dioxide
At the present time, there is shortage of carbon dioxide, that I wrote about in Food Shortages Looming After Factory Closures Hit Production.
In the related post, I said this.
Perhaps we should fit carbon capture to a handy gas-fired power station, like SSE are planning to do at Keadby and use this carbon dioxide.
Consider.
- The Keadby complex of gas-fired power stations is close to a lot of depleted gas fields, some of which are in Lincolnshire and some are off-shore.
- Some gas fields are already being used to store natural gas imported from Norway.
- SSE plan to fit the later power stations with carbon capture.
I talk about SSE’s plans in Energy In North-East Lincolnshire.
If SSE were to build four large gas-fired power stations at Keadby, I calculated that they would produce 5.4 million tonnes of carbon dioxide per year.
It could be used or stored in depleted gas fields according to demand.
But the complex at Keadby would not release any carbon emissions.
Could Carbon Capture Be A Nice Little Earner?
If demand for carbon dioxide continues to rise, I could see power companies installing carbon capture on gas-fired power stations to generate an extra income stream.
Incidentally, there are 55 operational gas-fired power stations in the UK, that can generate a total of 30 GW, which are owned by perhaps ten different companies.
Development of carbon capture systems could be helped by Government subsidy.
Conclusion
I have long forgotten all the calculations I did with gases, but I do know that when one molecule of methane combusts it produces two molecules of water and one of carbon dioxide.
So I am fairly convinced that if you took X cubic kilometres of natural gas out of a gas field, after combustion there wouldn’t be anything like as much volume of carbon dioxide to put back, specially if a proportion could be used profitably in other processes.
If we are going to use gas to generate zero-carbon power, we probably need to do it with gas fields under our control either onshore or in the seas around our coasts. This is because the depleted gas fields can be used to store the carbon.
Gas-fired power stations with carbon capture supporting industries that need supplies of carbon dioxide will become a large part of our energy economy.
Food Shortages Looming After Factory Closures Hit Production
The title of this post, is the same as that of this article on The Times.
This is the first paragraph.
Acute food shortages were feared last night after high gas prices forced most of Britain’s commercial production of carbon dioxide to shut down.
In some ways, this is rather ironic, when on the one hand we are trying to stop the emission of carbon dioxide and on the other we haven’t got enough for important uses in the food industry.
Perhaps we should fit carbon capture to a handy gas-fired power station, like SSE are planning to do at Keadby and use this carbon dioxide.
If the shortage continues, there’ll be no dry ice for the pantomimes this Christmas.
FLXdrive ‘Electrifies’ Pittsburgh
The title of this post, is the same as that of this article on Railway Age.
The article describes Wabtec’s FLXdrive locomotive, as “the world’s first 100% battery, heavy-haul locomotive”
It is well worth a read, as it describes some of the design philosophy.
In addition, this page on the Wabtec web site gives some details of the locomotive.
It is powered by lithium-ion batteries.
- There are around 20,000 battery cells
- The batteries have their own air-conditioning
- There is a sophisticated battery-management system.
- The total battery size is 2.4 MWh
- Power output is 4400 HP or 3.24 MW
- Locomotive will run for 30-40 minutes at full power.
- The locomotive has regenerative braking.
- Operating speed is 75 mph
Note that running at 75 mph for 40 minutes would cover fifty miles.
The Railway age article has this paragraph, which describes a partnership between Carnegie-Mellon University (CMU), Genesee & Wyoming and Wabtec to create the Freight Rail Innovation Institute.
CMU, Genesee & Wyoming and Wabtec also hope to create the Freight Rail Innovation Institute, described as “the first-of-its-kind effort to create zero-emission locomotives, develop technology that increases freight rail utilization and improve safety by 50%, and create 250,000 jobs by 2030.” G&W’s Buffalo & Pittsburgh Railroad will pilot technologies developed by the Freight Rail Innovation Institute, including a zero-emissions battery and hydrogen-powered train that is planned for revenue operation on 200 miles of track between Pittsburgh and Buffalo, N.Y. within the next three years.
Note.
- The paragraph is very much a mission statement.
- Genesee & Wyoming are the parent of Freightliner in the UK, who are developing a dual-fuel locomotive, that I wrote about in Freightliner Secures Government Funding For Dual-Fuel Project.
It strikes me CMU, Genesee & Wyoming and Wabtec are on the right track.
