RheEnergise To Build First-Of-A-Kind Hydro Storage System

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

This is the sub-heading.

A demonstrator of the company’s long-duration hydro-energy storage system will be constructed at Sibelco’s Devon mine.

These are the first two paragraphs.

UK hydro-energy storage company RheEnergise is to build a first-of-a-kind demonstrator of its long-duration hydro-energy storage system at Sibelco’s mining operations at Cornwood, near Plymouth, Devon. The construction of the demonstrator will start soon, with commissioning scheduled in September.

The power generated by RheEnergise’s HD Hydro demonstrator, which has a peak power production of 500kW, will support Sibelco’s mining operations at times of high energy demand and help the company decarbonise its operations. The Cornwood site produces kaolin, mainly for sanitary ware, ceramics, tiles and industrial applications.

I have some thoughts.

A Short Construction Time

If RheEnergise’s timescale is correct and it is the same in RheEnergise’s original press release, then I can draw the following conclusions.

  • Five months is a short construction time.
  • I would suspect that the system can be built from readily available components.
  • RheEnergise’s HD Hydro system, which uses a fluid with a specific gravity of 2.5 can work with standard pipes and turbines.

I wouldn’t be surprised, that the only difference between RheEnergise’s system and a standard water-based hydro system is the fluid and a few settings on the control system.

It might even be possible to check that the system works by using water as the storage fluid.

But that would of course shorten the testing time.

Could An Existing Pumped Storage System Be Uprated With RheEnergise’s Fluid?

Consider

  • There are only a few small pumped hydro systems.
  • The RheEnergise system needs to be sealed.
  • The storage capacity would be raised by 2.5 times.

It is an interesting idea, but could be possible in some cases.

What Will Be The Storage Capacity Of The Sibelco System?

This is not stated, but typically a battery system has a duration of two hours.

So that would give a capacity of 1 MWh.

Could RheEnergise’s HD Hydro System Back Up A Wind Or Solar Farm?

Consider.

  • Batteries are always a good addition to a wind or solar farm, as they stabilise the output.
  • A lot would depend on the possible size of the RheEnergise system battery.
  • The location of the wind farm is probably important.

An onshore wind farm on top of a hill might be an ideal candidate.

Conclusion

RheEnergise could be installed in a lot of sites.

Octopus Energy Invests In Floating Offshore Wind Tech Company

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

This is the sub-heading.

Octopus Energy’s generation arm has invested in US-headquartered Ocergy to boost the development of floating offshore wind farms globally.

These are the first three paragraphs.

According to Octopus, Ocergy has an innovative approach to designing and manufacturing floating foundations, reducing the time and cost of building them.

Ocergy is pioneering a hyper-local supply chain approach, working with local manufacturers and creating green jobs in the areas where the wind turbines are installed, said the company.

Further efficiencies are unlocked through Ocergy’s lighter and modular designs which make the turbine foundations easy to transport and assemble at their final destination, according to the press release.

This page on the Ocergy web site contains the press release, mentioned in the article.

These are some sentences from the press release.

  • Ocergy, which is headquartered in the US and has operations in France, is pioneering a hyper-local supply chain approach, working with local manufacturers and creating green jobs in the areas where the turbines are installed.
  • Further efficiencies are unlocked through Ocergy’s lighter and modular designs which make the turbine foundations easy to transport and assemble at their final destination.
  • Floating foundations are used in areas with coastlines that are too deep for foundations that are fixed to the seabed. Around 80% of global offshore wind resources are located in deep waters, underscoring this technology’s vast untapped potential.
  • It comes as governments across the globe have set ambitious targets for floating offshore wind. The UK alone is targeting 5 GW of floating offshore wind capacity by 2030.

I certainly like their approach.

believe that innovative designs and streamlined manufacturing will play a large part in installing the large amount of floating wind, that is planned by governments worldwide.

I also believe that because of the repetitive nature of the building of these floating structures, innovative project management software and systems will be developed.

I certainly have my own ideas for that!

National Grid Shares Proposals For Green Electricity Projects In Lincolnshire And West Norfolk, Needed To Boost Home-Grown Energy Supplies And Progress Towards Net Zero

The title of this post, is the same as that of this press release from National Grid.

These four bullet points, act as sub-headings.

  • National Grid is inviting communities in East Lindsey, Boston and South Holland in Lincolnshire, and King’s Lynn and West Norfolk, to view proposals for two new primarily offshore electricity infrastructure projects.
  • National Grid will consult communities from 23 April – 17 June to introduce the proposed project and ask for local peoples’ opinions.
  • Eastern Green Link 3 (EGL 3) and Eastern Green Link 4 (EGL 4) will be able to transport enough clean energy generated in Scotland to power up to four million homes in the Midlands and South of England.
  • The projects form part of The Great Grid Upgrade, the largest overhaul of the grid in generations, with new infrastructure across England and Wales helping the UK to meet its net zero ambitions, reduce its reliance on fossil fuels and contribute to lower energy bills over the long-term.

These five paragraphs outline the two projects.

National Grid is inviting communities to comment on early proposals for two green electricity infrastructure projects which will help deliver the UK’s energy security strategy and net zero targets.

The eight-week initial consultation, which begins on 23 April, shares proposals for Eastern Green Link 3 (EGL 3) and Eastern Green Link 4 (EGL 4) projects – two new, primarily subsea high voltage direct current (HVDC) electricity links, with associated infrastructure, between Scotland and England.

National Grid Electricity Transmission (NGET) is jointly developing EGL 3 with SSEN Transmission (SSEN) and EGL 4 with SP Energy Networks (SPEN).

EGL 3 would run from Peterhead, Aberdeenshire, under the North Sea via marine cables to a potential landfall location on the Lincolnshire coastline, either at Theddlethorpe or Anderby Creek. EGL 4 would run from Westfield, Fife, also via marine cables under the North Sea to the same landfall location as EGL 3.

After making landfall, both projects’ cables will run underground for approximately 100km to two proposed converter stations in the Walpole, King’s Lynn and West Norfolk, area. Underground cables would then connect the converter stations to the transmission network via a new proposed substation, also within the Walpole area.

Note.

  1. These would appear to be early proposals.
  2. National Grid appear to be planning and consulting on two interconnectors at once.
  3. There would appear to be a lot of underground cable on land. But then the cables will be dug into good Fenland soil.
  4. All the electrical gubbins seem to be in the Walpole area.

These paragraphs invite people to comment.

Throughout our initial consultation, we are holding a series of face-to-face events to consult on the electrical infrastructure required in England.

Our consultation events are being held across the project area. Information about our proposals will be on display and copies of maps and technical documents will be available to view. Members of the project team will be available to talk through our proposals and answer any questions.

National Grid have also announced dates of when public information events are being held.

  • Tuesday 30 April 2024 – 2pm-7pm – Dunes Complex, Central Promenade, Mablethorpe, LN12 1RG
  • Wednesday 1 May 2024 – 2pm-7pm – Anderby Village Hall, Sea Road, Anderby, Skegness, PE24 5YD
  • Thursday 9 May 2024 – 12:30pm – 6pm – Alford Corn Exchange, 9 Market Place, Alford, LN13 9EB
  • Monday 13 May 2024 – 2pm-7pm – Leverington Village Hall, Gorefield Rd, Leverington, Wisbech, PE13 5AT
  • Wednesday 15 May 2024 – 2pm-7pm – Eastville, Midville and New Leake Village Hall, Station Rd, Eastville, PE22 8LS
  • Thursday 16 May 2024 – 2pm-7pm – Poachers Country Hotel, Swineshead Road, Kirton Holme, PE20 1SQ
  • Monday 20 May 2024 – 2pm-7pm – Walpole Community Centre, Summer Close, Walpole St Andrew, PE14 7JW
  • Wednesday 29 May 2024 – 2pm-7pm – The Holbeach Hub, Boston Rd South, Holbeach, PE12 7LR
  • Wednesday 5 June 2024 – 2pm-7pm – Burgh le Marsh Village Hall, Jacksons Lane, Burgh le Marsh, Skegness, PE24 5LA

I would have hoped, that some of the venues would have been easier to get to by public transport.

I have some thoughts and observations.

What Will Be The Capacity Of Green Link 3 And Green Link 4?

I can find references to the capacity of Eastern Green Links 1-4 and it appears that all four have a capacity of 2 GW.

A Map Of Green Link 3 And Green Link 4

I have found this map of Green Link 3 and Green Link 4.

National Grid are going to be busy, as they’re also building Green Link 1 and Green Link 2.

Will Green Link 3 And Green Link 4 Share A Route Between The Coast And Walpole?

There is only one green HVDC onshore cable on the map. But surely laying two 2 GW cables in the same trench will cost less, than digging two cable routes.

Looking at the three converter stations would appear to confirm that Green Link 3 and Green Link 4 share a route.

Will Landfall Be At Theddlethorpe Or Anderby Creek?

This Google Map shows the coast between Theddlethorpe and Anderby Creek.

Note.

  1. The decommissioned Theddlethorpe gas terminal is indicated by the red arrow.
  2. The seaside resort of Mablethorpe lies between the two possible landing sites.
  3. Anderby Creek  is in the South-East corner of the map.

This second Google Map shows the Theddlethorpe Gas Terminal and the North of Mablethorpe.

Note.

  1. The decommissioned Theddlethorpe gas terminal is indicated by the red arrow.
  2. Mablethorpe beach appears to be on a high quality.

Both sites would appear to be strong possibilities.

Both sites have plenty of space, but the Theddlethorpe gas terminal is a large brownfield site.

The Anderby Creek site would probably be a shorter underground cable across Lincolnshire.

The Triton Knoll Wind Farm

The Wikipedia entry for the Triton Knoll wind farm starts with these two paragraphs.

Triton Knoll Wind Farm is an 857 MW round 2 offshore wind farm 33 kilometres (21 mi) off the coast of Lincolnshire, in the North Sea, England.

RWE Npower Renewables were awarded the lease to the development area in 2003. The offshore elements of the wind farm of up to 1200MW power gained planning consent in 2013; RWE reduced the scope of the wind farm to 900MW or under in 2014, to reduce cost per MW.

Note.

  1. The wind farm was commissioned in January 2022.
  2. The wind farm cables make landfall at Anderby Creek.
  3. They then travel underground to Bicker Fen substation.

This Google Map shows Bicker Fen and Anderby Creek.

Note.

  1. Bicker Fen substation is in the South-West corner of the map and is indicated by a red arrow.
  2. Anderby Creek is in the North-East corner of the map.
  3. The cable is underground.
  4. This page on the Murphy Group website, describes the work the company did to install the cables.
  5. It appears from the Murphy document, that there are six cables between Anderby Creek and Bicker Fen.

This Google Map shows Anderby Creek.

Could the scar across the land to the West of Anderby Creek, be the connection to the offshore Triton Knoll wind farm?

I think it is! And I also think that it can carry more than just the 857 MW Triton Knoll wind farm!

I am suspicious, that one of Baldrick’s ancestors has been at work and the Triton Knoll export cable system could be used to connect Green Link 3 and Green Link 4 to Bicker Fen and Walpole substations.

This would surely allow Scottish wind power to be sold to Denmark and then sold onward to Germany.

The VikingCCS Project

The VikingCCS project is a carbon capture and storage project, that is proposed to be based at the decommissioned Theddlethorpe gas terminal.

The VikingCCS project has a web site.

Would the use of the Theddlethorpe gas terminal mean that it is more likely that Green Link 3 and Green Link 4 will make a Southern landfall at Anderby Creek?

Will There Be A Connection To Viking Link?

The Viking Link is a 1400 MW at 525 KV electricity interconnector between Bicker Fen in Lincolnshire and Revsing in Jutland, Denmark.

This Google Map, shows the location of Bicker Fen, about halfway between Boston and Sleaford.

This second map shows the position of the current Walpole substation with respect to the Wash.

Note.

  1. Bicker Fen is in the North-West corner of the map.
  2. The current Walpole substation is marked by the red arrow.
  3. King’s Lynn is in the South-East corner of the map.

I suspect, if National Grid wanted to connect Green Link 3 and Green Link 4 to the Viking Link, then this would be possible.

If the Viking Link were to be connected to Green Link 3 and Green Link 4, this would allow surplus Scottish renewable energy to be sent to Denmark and on to Germany.

Green Link 3, Green Link 4 And Viking Link Appear To Be Underground In Lincolnshire

I can’t find any trace of overhead cables for the Viking Line in Lincolnshire and the press release says this about Green Link 3 and Green Link 4.

After making landfall, both projects’ cables will run underground for approximately 100km to two proposed converter stations in the Walpole, King’s Lynn and West Norfolk, area.

The connection to the Triton Knoll wuind farm is also underground.

It does appear that National Grid, are going for a Nimby-friendly approach for cables between Walpole and the coast.

Hopefully putting the cables underground will save money in legal arguments and fees.

BW Ideol Unveils Mass Production-Ready Floating Wind Foundation

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

This is the sub-heading.

France-based BW Ideol has unveiled its standardised floating foundation product and a blueprint for mass production that could drive costs down across projects.

This is the first paragraph.

With over 22 GW already awarded in Scotland, around 8 GW in the US, and several GW currently being awarded or in the tendering phase elsewhere in the world, the floating wind is now entering an industrialization phase, said BW Ideol.

It looks like the French have come up with a solution that’s needed.

These are previous posts about BW Ideol.

There is also this video of proposed serial production of BW Ideol floaters at the Port of Ardersier.

This Google Map show the area of Scotland to the North-East of Inverness Airport.

Note.

  1. Inverness Airport indicated by the red arrow.
  2. Ardersier village in the middle of the map on the bay.
  3. Fort George is at the North end of the bay.

The Port of Ardersier is the large slab of concrete in the North-East corner of the map, the Carse of Ardersier marked below it.

BW Ideol are claimining they can build one floater a week or one GW a year.

World’s First Energy Island Starts Taking Shape – Video

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

This is the sub-heading.

The first of the 23 caissons being built for Princess Elisabeth Island in Vlissingen, the Netherlands, is almost finished and will be immersed in the North Sea this summer. The artificial Belgian energy island is a world first.

Note.

  1. This web site is the web site of Belgium’s Princess Elisabeth energy island.
  2. This YouTube video describes the Princess Elisabeth island.

The video shows the importance of this project, that will have interconnectors to both the UK and Denmark, and connections to a large number of offshore wind farms.

These two paragraphs describe the roll-out of the caissons.

When the caissons are ready, a semi-submersible vessel will transport them further down the harbour, where they will be placed in the water and temporarily stored. They will then be moved to their final location in the North Sea this summer, weather permitting.

The caissons will form the outer walls of the energy island. The island itself will be created using approximately 2.3 million square metres of sand, extracted locally. The island will be finished in late 2026, when the electrical equipment can start to be installed. Contracts for this will be tendered this year.

These pictures show four Pheonix Caissons from Mulberry Harbours that are used as a museum in The Netherlands.

Nothing is new! But at least the Belgians won’t have to tow their caissons across the Channel under enemy fire.

A Video Description Of Princess Elisabeth Island

This web site is the web site of Belgium’s Princess Elisabeth energy island.

This YouTube video describes the Princess Elisabeth island.

From the video the following can be determined.

  • The Princess Elisabeth island is 45 km. from the Belgian coast.
  • An interconnector to the UK could come ashore at the site of the decommissioned Bradwell nuclear power station.
  • An interconnector to Denmark could come ashore in Southern Jutland, just North of where the Viking Link connects to Denmark.

This map clipped from the video shows the location of Princess Elisabeth island.

Note.

  1. Belgium is shown in red.
  2. Istend is in the middle of the straight Belgian coast.
  3. The red dot between Belgium and the UK is Princess Elisabeth island.
  4. The interconnector to the UK could feasibly go to Bradwell.
  5. The interconnector to Denmark could go via a wind farm, which would explain the kink.
  6. Could the kink point be at the Dogger Bank, where there could be 20 GW of wind farms?

Has Belgium made a bid to dominate European energy distribution?

This Google Map shows the Belgian and English coast lines.

Note.

  1. Bradwell is on the coast to the North-East of Southend-on-Sea.
  2. As it used to be a nuclear power station site it still has an electricity connection to the grid.
  3. The Princess Elisabeth island is 45 km. from the Belgian coast at Ostend.

I estimate that a Bradwell and Princess Elisabeth island interconnector would be about 150 miles.

Denmark Launches Massive Offshore Wind Auction

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

This is the sub-heading.

Denmark has opened a new offshore wind tender, the country’s largest ever, offering a minimum of 6 GW of new capacity spread over six wind farms, with the overplanting option allowing for 10 GW or more of new capacity to be added.

These are two paragraphs from the article.

The offshore wind farms must deliver at least 6 GW, and as a new element, there will be freedom to establish as much offshore wind as possible on the tendered areas, with the exemption of Hesselø with a maximum capacity of 1.2 GW.

If the market utilizes this freedom to optimize the usage of the areas, it could result in the construction of 10 GW offshore wind or more, the agency said.

Recently, some wind farms in the UK have been increased in size after the auction.

In Crown Estate Mulls Adding 4 GW Of Capacity From Existing Offshore Wind Projects, I note how 4 GW of overplanting could be employed to raise the total capacity from 4.6 GW to 8.6 GW.

So have the Danes decided to build expansion into the tender?

One of the wind farms in the auction is called Nordsøen I.

  1. It will be about 50 km. from the West Coast of Denmark.
  2. It appears it will have a capacity of at least 1 GW.
  3. It could connect to the shore, not far from where the Viking Link between Lincolnshire and Denmark connects to the Danish grid.
  4. There is a 700 MW interconnector between the area and Eemshaven in The Netherlands.
  5. There is 1.5 GW of overland transmission lines to Germany.

All these connections, increase energy security for Denmark, Germany, the Netherlands and the UK.

Could the Danes be building the Nordsøen I, so it could work with the all the connections in Southern Jutland and improve energy security?

New National Grid Substation Fully Operational, Transmitting Clean Power To 1.5 Million Homes

he title of this post, is the same as that of this press release from National Grid.

These three bullet points act as sub-headings.

  • National Grid’s new Littlebrook 400kV substation in Dartford, Kent is now fully energised.
  • The facility enables the transmission of 2GW of low carbon and renewable energy from interconnectors and offshore wind farms off the coast of Kent to power around 1.5 million homes.
  • New technology deployed to reduce emissions at the site.

This is the first three paragraphs, which outline the project.

National Grid has successfully commissioned a new, state-of-the-art substation, in Dartford, Kent, enabling 2 gigawatts (GW) of low carbon and renewable energy to power around 1.5 million homes.

National Grid and its contractors Balfour Beatty and GE Vernova’s Grid Solutions have been working since June 2019 to build a replacement for Littlebrook 400kV substation.

The new facility will help to reduce the use of sulphur hexafluoride (SF₆), a gas commonly used in the electrical industry to prevent short circuits and to keep the network safe and reliable.

These two paragraphs explain how the new substation fits in with National Grid’s SF₆ policy.

Engineers are using GE Vernova Grid Solutions’ innovative g3 gas-insulated busbar equipment which is SF6- free. A total of 5.6 tonnes of SF₆ gas has been saved, forming part of National Grid’s ambition to reduce its SF₆ emissions by 50% by 2030 and removing all SF₆ gas from electrical assets by 2050.

Teams have also deployed net zero construction methods throughout the project to reduce the environmental impact of the works, including steel manufactured in Britain, solar powered electrics, electric vehicle charging points, biodiversity net gain plan for the local area and an onsite biodigester to manage wastewater, all saving 5229 tonnes of CO₂ emissions during construction.

National Grid have this page on their web site, which is entitled What Is SF6? Sulphur Hexafluoride Explained, where this is the first paragraph.

Sulphur hexafluoride – also known as SF6 – is a ‘greenhouse gas’ that has long played a part in global warming, similar to that of carbon dioxide (CO2).

Hence the need for its removal.

Conclusion

Removal of sulphur hexafluoride from the world’s electricity substations and switchgear will be a very large task.

BW Ideol And Holcim To Explore Use of Low-Carbon Concrete In Floating Offshore Wind

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

This is the sub-heading.

BW Ideol and Holcim have signed a Memorandum of Understanding (MoU) for a feasibility study on supplying beneficial low-carbon concrete for the floating offshore wind industry, with particular reference to Scotland.

These are the first three paragraphs.

BW Ideol and Holcim aim to collaborate on optimising the supply of the innovative concrete needed for the intended mass production of BW Ideol’s floaters in the Port of Ardersier.

Low-carbon concrete’s advantages as a building material for offshore wind farms include its durability in marine environments, its local availability and its comparatively lower carbon emissions, the companies said.

The collaboration includes developing specific durable maritime low-carbon concrete mixes with enhanced mechanical performance perfectly suited to slipform application.

This is surely a good development.

Europe’s First Commercial-Scale Floating Offshore Wind Farm Secures All Planning Approvals

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

This is the sub-heading.

Flotation Energy and Vårgrønn, a joint venture between Plenitude (Eni) and HitecVision, have obtained the offshore planning approval for the Green Volt floating wind farm offshore Scotland.

This is the first paragraph.

With onshore consent announced earlier this month, Green Volt has now received all its planning approvals and remains on track to be the first commercial-scale floating offshore wind farm in Europe.

Note.

  1. This is the Green Volt web site.
  2. Capacity will be between 300 and 560 MW.
  3. It should be fully operational by 2029.
  4. It is an INTOG wind farm designed to decarbonise offshore oil and gas fields.

It will also have the side effect of bringing more gas ashore in the UK, instead of burning it to power the platforms.
