Ørsted, Simply Blue, Subsea7 Submit Application For 100 MW Scottish Floating Wind Farm

The title of this post, is the same as that of this article on offshoreWIND.biz.

This is the sub-heading.

Ørsted, Simply Blue Group and Subsea7, through their joint venture partnership in Scotland, have submitted an offshore consent application for the proposed 100 MW Salamander floating offshore wind farm, one of the 13 projects selected in Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round.

The article starts with a map that shows the location of the Salamander floating offshore wind farm and it shows how the sea is getting very crowded 35 kilometres off Peterhead.

This map shows the various ScotWind leases, around the North of Scotland.

 

The numbers are Scotwind’s lease number in their documents.

These are the Scotwind wind farms to the North-East of Scotland.

  • 1 – BP Alternative Energy Investments – 859 km² – 2.9 GW – Fixed
  • 2 – SSE Renewables – 859 km² – 2.6 GW – Floating
  • 3 – Falck Renewables Wind – 280 km² – 1.2 GW – Floating
  • 4 – Shell – 860 km² – 2.0 GW – Floating
  • 5 – Vattenfall – 200 km² – 0.8 GW – Floating
  • 6 – DEME – 187 km² – 1.0 GW – Fixed
  • 9 – Ocean Winds – 429 km² – 1.0 GW – Fixed
  • 10 – Falck Renewables Wind – 134 km² – 0.5 GW – Floating
  • 11 – Scottish Power Renewables – 684 km² – 3.0 GW – Floating
  • 12 – BayWa r.e. UK  – 330 km² – 1.0 GW – Floating

Note.

  1. Salamander is located to the South of wind farms 10, 11 and 12 and to the North-West of wind farm 5.
  2. These windfarms total up to 16 GW.
  3. 4.9 GW are fixed foundation wind farms.
  4. 11.1 GW are floating wind farms.

These are my thoughts.

The Salamander Project

In the big scheme of things, the 100 MW Salamander wind farm, is rather a tiddler of a wind farm.

On the Salamander wind farm web site, a section gives the Project Goals.

  1. Our innovative pre-commercial stepping-stone concept will use novel floating foundations to (i) maximise Scottish content, (ii) enable the Scottish supply chain to gear up for the future floating offshore wind commercial opportunities in ScotWind and (iii) reduce the financial, environmental and technology risks of floating offshore wind.
  2. The Salamander project will contribute to the Scottish Government and UK Government net-zero targets. The project can contribute to the Scottish government’s target of 11 GW of installed offshore wind by 2030, as well as the UK government’s target of 5 GW of operational floating offshore wind by the same date.
  3. We are dedicated to developing a sustainable and transformative project, working with the oceans, and enabling communities to benefit from Project Salamander. Therefore, we commit to having a continuous and strong stakeholder and community engagement.

It appears to me, that the Salamander project will be a pathfinder for the 11.1 GW of floating wind farms to be built off Peterhead.

Bringing The Electricity South

National Grid are building four interconnectors between Eastern Scotland and Eastern England.

  • Eastern Green Link 1 – Torness and Hawthorn Pit
  • Eastern Green Link 2 – Peterhead and Drax
  • Eastern Green Link 3 – Westfield and Lincolnshire
  • Eastern Green Link 4 – Peterhead and Lincolnshire

Note.

  1. All interconnectors are 2 GW.
  2. All interconnectors are offshore for a long part of their route.
  3. It also appears that National Grid are burying much of the onshore sections.

But the 4 GW of interconnectors will only be able to bring a quarter of the offshore electricity generated in the Peterhead area to the South.

What Will Happen To The Excess Electricity?

Consider.

  • There could be 16 GW of planned offshore wind power around Peterhead and North-East Scotland.
  • There is only 4 GW of interconnector capacity between Peterhead and Eastern England.
  • There is another 6.8 GW of electricity around North-West Scotland.
  • There is 2.8 GW of electricity being developed to the East of Shetland.
  • The Crown Estate is thinking of increasing the size of some offshore wind farms.

It is likely, that other wind farms will be built in the seas around the North of Scotland.

It appears that the North of Scotland could have at least 20 GW of excess electricity.

Possible solutions would include.

  • Developing energy intensive industries like metal refining.
  • More interconnectors to Denmark, England, Ireland and Norway.
  • Storage of the electricity in giant pumped storage hydroelectric power stations.
  • Creation of green hydrogen for export.

Note.

  1. Aluminium refining has been developed in the North of Scotland before.
  2. More interconnectors are a possibility, especially as Scotland is developing cable manufacturing capacity.
  3. Some maps show extra interconnectors between West Scotland and Merseyside.
  4. At least 70 GWh of pumped storage hydroelectric power stations are being developed along the Great Glen.
  5. I suspect that the pumped storage hydroelectric power stations could be connected to the wind farms, by cables under the waters of Loch Ness.

But surely, production of green hydrogen for export would be a very good way to go.

  1. Extra electrolysers could be added as required.
  2. Because of the interconnectors down both East and West Coasts, electrolysers could be built in England, where there is a large need for hydrogen.
  3. Hydrogen would be exported initially by tanker ships.
  4. At some point in the future, it might be viable to build a hydrogen pipeline to connect to the growing European hydrogen network.

The giant pumped storage hydroelectric power stations and the hydrogen electrolysers would be sized to make sure, that no wind power is never wasted.

Conclusion

The 100 MW Salamander floating wind farm may only be small, but it will prove the technology, the manufacturing and the supply chains, so that Scotland can have a second energy boom from the North Sea.

But this boom will certainly last longer than a hundred years.

Europe’s Mines Look To Gravity Energy Storage For Green Future

The title of this post, is the same as that of this article on Global Mining Review.

This is the sub-heading.

Mine owners across Europe are looking at a new form of underground energy storage to offer a low carbon future as operations wind down.

These are the first four paragraphs.

Active deep mine operators in Slovenia, Germany, The Czech Republic and Finland are all examining how underground gravity energy storage – provided by Edinburgh firm Gravitricity – could offer green opportunities to mining communities facing a downturn in employment.

Gravitricity has developed a unique energy storage system, known as GraviStore, which uses heavy weights – totalling up to 12 000 t – suspended in a deep shaft by cables attached to winches.

This offers a viable alternative future to end of life mine shafts, which otherwise face costly infilling and mine decommissioning costs.

They have teamed up with energy multinational and winch specialist ABB alongside worldwide lifting specialists Huisman to commercialise the technology for mine operators.

Note.

  1. Four projects are mentioned.
  2. It appears to be less costly, than infilling.
  3. Gravitricity have teamed with ABB and Huisman, who are two of Europe’s specialist in this field.
  4. You can’t have too much energy storage.

The article is worth a full read.

Conclusion

Gravitricity’s simple idea could be a big winner.

Are Scotrail Going To Replace The Inter7City Trains With Hydrogen-Powered Trains?

This article in The Times is entitled The Caley Is Ready To Roll With New Venture Building Trains.

I feel that this is one of the most significant paragraphs in the article.

ScotRail has indicated that it wants to replace nearly two thirds of its fleet with new, low-carbon rolling stock between 2027 and 2035, comprising about 675 carriages in total, with an initial core order of 64 four and five-car units. A spokesman confirmed: “We are working on a business case that will go to the Scottish government for the procurement of a new suburban train fleet.”

The current Scotrail fleet includes.

  • 25 Inter7City trains which comprise 52 Class 43 power cars and 120 Mark 3 carriages – Diesel – 120 cars – 1975
  • 5 Class 153 trains  – Diesel – 5 cars – 1987
  • 42 Class 156 trains – Diesel – 84 cars – 1987
  • 40 Class 158 trains – Diesel – 80 cars – 1987
  • 30 Class 170 trains – Diesel – 90 cars – 1998
  • 21 Class 318 trains – Electric – 63 cars – 1985
  • 34 Class 320 trains – Electric – 66 cars – 1990
  • 40 Class 334 trains – Electric – 120 cars – 1999
  • 38 Class 380 trains – Electric – 140 cars – 2009
  • 70 Class 385 trains – Electric – 234 cars – 2015

Note the last three fields are the traction type, total number of cars and the build year of the first train.

I will split these trains into four groups.

  • Inter7City – Diesel – 25 trains – 120 cars
  • BR Diesel – Diesel – 117 trains – 259 cars
  • BR Electric – Electric – 55 trains – 129 cars
  • Modern Electric – Electric – 148 trains – 494 cars

Note.

  1. This is a grand total of 345 trains and 1002 cars.
  2. Ignoring the modern electric trains and the total is 197 trains and 508 cars.
  3. The total for diesel trains is 142 trains and 359 cars.
  4. As Great Western Railway have withdrawn their similar GWR Castles, there must be reasons for Scotrail to do the same.

I will now look at replacement strategies, based on this statement from Scotrail.

ScotRail has indicated that it wants to replace nearly two thirds of its fleet with new, low-carbon rolling stock between 2027 and 2035, comprising about 675 carriages in total, with an initial core order of 64 four and five-car units.

I would expect 675 carriages would be about 232 trains, if the current average train length of just under three cars is carried over.

The Effect Of 675 New Carriages

Assuming that no modern electric trains were replaced, this would create a fleet size of at least 1169 carriages.

This would be a sixteen percent increase in carriages, which would be welcome news for some rail users.

The Initial Core Order Of 64 Four And Five-Car Units

All we know of this order, is the number of trains and that they will be new and low-carbon, according to indications from Scotrail.

Low-carbon would mean one of these traction options.

  • Electric trains with full electrification.
  • Battery-electric trains with partial-electrification.
  • Hydrogen-powered trains.

Note.

  1. The heritage Taliban would object violently to full electrification of some historic routes.
  2. UNESCO would probably remove the World Heritable Site status to the Forth Bridge if it were to be electrified.
  3. Scotland is developing a hydrogen infrastructure.
  4. Hydrogen-powered trains have long ranges in the order of a thousand kilometres.
  5. Hydrogen-powered trains are essentially electric trains with a hydrogen fuel-cell to provide electricity as needed.
  6. Hydrogen-powered trains would need very little new infrastructure, except for a network of refuelling points across Scotland.
  7. Well-designed battery-electric and hydrogen-electric trains, should be very quiet and comfortable for passengers.

As an engineer, I would choose hydrogen-power for the initial core order.

Where would the initial core order be deployed?

Twenty-five would be used to replace the carbon-emitting elderly Inter7City trains.

These routes could probably handle the other forty.

  • Aberdeen and Inverness
  • Edinburgh/Glasgow and Aberdeen.
  • Edinburgh/Glasgow and Inverness.
  • Glasgow and South Western Line
  • West Highland Line.

Note.

  1. A lot of diesel trains would be retired.
  2. Trains could be designed, for tourists with proper cycle spaces.
  3. The West Highland Line would get the five-car trains it needs.

This would be a good start.

Conclusion

It looks to me, that the Inter7City trains will be going and will be replaced by new trains.

But will Scotland take the great leap forward and power the new trains by Scottish hydrogen?

Blackwall Tunnel Southbound Route To Close For Four More Weekends

The title of this post, is the same as that of this article on the BBC.

This is the sub-heading.

Part of the Blackwall Tunnel will close this weekend as work continues on the Silvertown Tunnel.

These three paragraphs detail the closures.

The southbound route will be closed from 00:01 BST Saturday until 05:00 Monday and on three further weekends.

The 57-year-old crossing is also due to shut on 1-3 June, 8-10 June and 29 June-1 July, as resurfacing and landscaping work is undertaken.

The Silvertown Tunnel is due to open in 2025, after which drivers using both tunnels will pay to cross the Thames.

At least the works to create the Silvertown Tunnel, seem to be progressing as planned.

But then London’s tunnels have generally been completed on time.

Aura Power Secures £10 Million Funding From Novuna

The title of this post, is the same as that of this article on Solar Power Portal.

These two paragraphs introduce the deal.

Aura Power has announced the successful closing of a £10 million debt facility with Novuna Business Finance. Novuna is a part of Mitsubishi HC Capital UK PLC, designed to support projects from early development through to the operational phase.

Bristol-based Aura Power is developing an active pipeline of utility-scale solar PV and battery energy storage of about 12GW in the UK, Europe and North America. The funding will help progress global development for Aura, covering expenditures like grid payments, planning fees and legal land costs.

These two paragraphs describe some of Aura’s projects.

In December 2023, Aura was granted planning permission for a 100MW/400MWh battery energy storage (BESS) project in Capenhurst, Cheshire. It was the third UK project to receive planning permission last year, alongside Aura’s 49.9MW Horton Solar Farm located in East Devon and its 49.9MW Hawthorn Pit Solar Farm in Durham.

Aura has been active within the solar and battery industries, with a pipeline in development in excess of 20GW. Last week (2 May), following an appeal, the developer secured planning permission for an Essex solar farm that will have an export capacity of 30 MW.

Nearly, forty years ago, I started a finance company in Ipswich with a friend. Our financing was mainly directed towards truck leasing for companies moving containers to and from the Port of Felixstowe.

Before, I committed my money to that venture, I built a large mathematical model of the proposed business. I found, that there were some unique financial properties to leasing quality trucks, that meant losing large sums of money were difficult.

I wouldn’t be surprised that leasing battery energy storage (BESS) systems have a lot of things going for them, if you have the right contract.

This may explain, why there a large number of companies in the market of providing grid batteries.

  • At the top end; Centrica, Rolls-Royce and SSE will supply you with one.
  • Funds like Gore Street and Gresham House and others allow you to invest in batteries.
  • At the other end of the market are companies like Aura Power.

I suspect, that as with truck-leasing company, the financial flows are very stable and investor-friendly, if you get the model right.

Northern Lights Stun UK In Spectacular Display

The title of this post, is the same as that of this article on the BBC.

This is the sub-heading.

The Northern Lights have made a rare appearance across the UK, delighting sky watchers up and down the country.

These three paragraphs add more detail.

Excited onlookers shared pictures of the lights, also known as aurora borealis, visible right across the country, including the south coast of England – and if you missed it you are likely to have a chance to see it again on Saturday night.

They could be seen after one of the strongest geomagnetic storms for years hit Earth, with the US National Oceanic and Atmospheric Administration (NOAA) issuing a rare solar storm warning.

Such storms increase people’s chances of seeing the lights.

But how did the weather effect me?

  • Yesterday, my INR was 2.4.
  • I then had a terrible night, as I tossed and turned.
  • I even had to get up twice in the middle of the night to remake the bed.
  • This is so unlike me.
  • In the morning my INR was 2.2.

Was the reduction because low pressure sucked the water out of my body?

That is nnot in itself dangerous, but I do think, that there will have been a lot of strokes last night.

I wrote about this in Do Thunderstorms Cause Strokes?.

C-Capture Launches Innovative Carbon Capture Trial For Cement Industry 

The title of this post, is the same as that of this news item from C-Capture.

This is the sub-heading.

C-Capture, developers of next generation technology for carbon dioxide removal, has launched a new carbon capture trial in the cement manufacturing sector in partnership with Heidelberg Materials.

This is the first paragraph.

The trial, which utilises C-Capture’s innovative solution for industrial decarbonisation, is taking place at Heidelberg Material’s cement manufacturing plant in Ketton. It forms part of C-Capture’s national project, ‘XLR8 CCS – Accelerating the Deployment of a Low-Cost Carbon Capture Solution for Hard-to-Abate Industries’. Working with project partners across the UK, C-Capture’s XLR8 CCS project will demonstrate that a low-cost carbon capture solution is a reality for difficult-to-decarbonise industries in the race to net zero.

I wrote about C-Capture’s technology in Could Drax Power Station Solve The Carbon Dioxide Shortage?

The technology appears to have been spun out of Leeds University.

BP and Drax are investors.

This page on the C-Capture web site is called Technology and has a very neat interactive guide to how the technology works.

Conclusion

I have high hopes for this company and its technology.

Gluten Sensitivity And Epilepsy: A Systematic Review

Yesterday, The Times published this article, which was entitled ‘Game-Changing’ NHS Laser Therapy To Prevent Epileptic Seizures.

One reader had made this comment.

Be ace too if they can tweak to help migraine.

I used to suffer from something like migraine about thirty years ago. But after being found to be coeliac and going gluten-free, what ever it was seemed to disappear from my life.

Type “Coeliac Disease and Migraine” into Dr. Google and there are lots of references.

This indicates to me that serious scientists and doctors, must believe there could be a link.

There certainly is with me and going gluten-free eased my migraine-like symptoms.

I then typed “Coeliac Disease and Epilepsy” into Dr. Google and found this paper, which was entitled Gluten Sensitivity And Epilepsy: A Systematic Review.

This information is from the Abstract of the paper

Objective

The aim of this systematic review was to establish the prevalence of epilepsy in patients with coeliac disease (CD) or gluten sensitivity (GS) and vice versa and to characterise the phenomenology of the epileptic syndromes that these patients present with.

Methodology

A systematic computer-based literature search was conducted on the PubMed database. Information regarding prevalence, demographics and epilepsy phenomenology was extracted.

Results

Epilepsy is 1.8 times more prevalent in patients with CD, compared to the general population. CD is over 2 times more prevalent in patients with epilepsy compared to the general population. Further studies are necessary to assess the prevalence of GS in epilepsy. The data indicate that the prevalence of CD or GS is higher amongst particular epileptic presentations including in childhood partial epilepsy with occipital paroxysms, in adult patients with fixation off sensitivity (FOS) and in those with temporal lobe epilepsy (TLE) with hippocampal sclerosis. A particularly interesting presentation of epilepsy in the context of gluten-related disorders is a syndrome of coeliac disease, epilepsy and cerebral calcification (CEC syndrome) which is frequently described in the literature. Gluten-free diet (GFD) is effective in the management of epilepsy in 53% of cases, either reducing seizure frequency, enabling reduced doses of antiepileptic drugs or even stopping antiepileptic drugs.

Conclusion

Patients with epilepsy of unknown aetiology should be investigated for serological markers of gluten sensitivity as such patients may benefit from a GFD.

My Thoughts

These are my thoughts.

Coeliacs Prior To 1960

Consider.

  • Even if my excellent GP; Doctor Egerton White, felt I was coeliac, there was no test until 1960 for coeliac disease.
  • And the test that was developed using endoscopy wasn’t anywhere near to the endoscopies of the present day.
  • My late wife, who was a family barrister, likened the test to child abuse on a young child.
  • I have heard some terrible horror stories of doctors looking for coeliac disease in young children in the 1950s.
  • But there were some successes. A friend of mine, who is in her eighties, was successfully diagnosed by her parents using food elimination. But they were both GPs.
  • Recently, I’ve met two elderly ladies, who only in the last couple of years have been diagnosed as coeliacs.

Luckily, I was never tested until 1997 and I was diagnosed in 48 hours, by gene testing.

Methodology

The methodology was based on a systematic computer-based literature search of the PubMed database.

This has these advantages.

  • The rules for the search can be published and peer-reviewed.
  • Its Wikipedia entry says PubMed is a free database including primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics.
  • The technique can surely be applied repeatedly, to see how results are changing with time.
  • The search can be modified to analyse any topic, drug or condition, that appears in the PubMed database.
  • The analysis could surely be applied to other databases.

As a writer of data analysis software, developing this sort of software, would be really enjoyable.

Excitement Brewing for Gateshead FC Away At Wembley

The title of this post, is the same as that of this news item on Lumo.

This is the sub-heading.

Lumo, the Open Access rail operator, has teamed up with local Gateshead brewery Black Storm to offer Gateshead FC fans a special commemorative beer onboard its trains.

These first two paragraphs add a few more details.

Hot on the heels of Tyneside based Lumo, the Open Access rail operator, announcing an extra train on Saturday 11th May to get Gateshead FC fans back from London as part of the club’s huge achievement of a second Wembley FA cup final in as many years, they’ve teamed up with local Gateshead brewery Black Storm to offer fans and travellers a special commemorative beer onboard its trains.

The appropriately named’ Whistle Stop’ is a 5% ABV Helles Lager featuring special commemorative Gateshead FC Wembley 2024 and Lumo branding on the can and will be available to purchase on the LumoEats at seat trolley service on all Lumo trains from this week, including on its specially named ‘Heed Army Express’ trains on Saturday 11th (running from Newcastle to London at 07:12 and 10:22, and returning at 20:26).

Surely, rail companies should do more deals like this to support local teams and suppliers.

BaroMar Appoints Jacobs To Design First Large-Scale Project

The title of this post, is the same as that of this article on Energy Storage News.

These three paragraphs outline the project.

LDES technology BaroMar has enlisted consultancy Jacobs to develop the preliminary design for an underwater, large-scale pilot project with 4MWh of energy storage capacity using its technology off the coast of Cyprus.

The 4MWh project would store compressed air in large rigid tanks ballasted on the seabed, making it a form of compressed air energy storage (CAES), one of the more commercial mature LDES technologies.

BaroMar claims that the underwater nature of its solution gets around the main regulatory and geographical constraints of conventional CAES on land.

Note.

  1. BaroMar claim ‘Unmatchable low construction costs.’
  2. They also claim there is little underwater maintenance.
  3. BaroMat’s web site has this explanatory video.

The video says the following.

  • The system works in between 200 and 700 metres of water.
  • Installation costs are about $80 per kWh.
  • This means that the 4 MWh system in Cyprus would cost around $320,000.

I like the technology, which is a clever use of water to create pressure, to recover the stored energy.

Conclusion

I can see the technology being used to handle several different problems, with some being in the powering of offshore equipment.
