UK, Netherlands To Connect Grids via Nederwiek 3 Offshore Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Dutch Climate and Green Growth Minister Sophie Hermans has included LionLink, said to be the first direct-current hybrid interconnector, in the country’s latest Offshore Wind Energy Development Framework. LionLink will use the offshore grid connection of Nederwiek 3 offshore wind farm in the Netherlands to connect to both the Dutch and the UK onshore high-voltage grids.
These are points from the article.
- The interconnector can also be used as an additional high-voltage link to exchange electricity between the countries.
- With LionLink now added to the offshore wind development framework, TenneT may now make investments in the project, which the Dutch transmission system operator (TSO) is realising in close cooperation with UK partner National Grid Ventures (NGV).
- Nederwiek 3 is planned to be launched in 2026.
The offshore grid between the UK and Europe is on its way.
Lakeside Facility Connects To Grid And Becomes UK’s Largest Transmission Connected Battery
The title of this post, is the same as that of this press release from National Grid.
These three bullet points, act as sub-headings.
- National Grid plugs TagEnergy’s 100MW battery project in at its Drax substation.
- Following energisation, the facility in North Yorkshire is the UK’s largest transmission connected battery energy storage system (BESS).
- The facility is supporting Britain’s clean energy transition, and helping to ensure secure operation of the electricity system.
This paragraph introduces the project.
A battery storage project developed by TagEnergy is now connected and energised on the electricity transmission network, following work by National Grid to plug the facility into its 132kV Drax substation in North Yorkshire.
- Lakeside Energy Park’s 100MW/200MWh facility is now the largest transmission connected BESS project in the UK following energisation.
- The new facility will boost the capacity and flexibility of the network, helping to balance the system by soaking up surplus clean electricity and discharging it back when the grid needs it.
- To ensure a safe connection, National Grid, working with its contractor Omexom, upgraded its Drax 132kV substation to accommodate the additional clean power.
- Works included extending the busbars – which enable power flows from generation source on to power lines – upgrading busbar protection and substation control systems, and installing an operational tripping scheme, all of which helps keep the network stable and operating securely.
Owned and operated by TagEnergy – with Tesla, Habitat Energy and RES as project partners – the newly-connected battery will help exploit the clean electricity potential of renewable projects in the region, storing and releasing green energy to power homes and businesses and also helping to relieve any system constraints.
National Grid’s adjacent Drax 400kV substation already hosts the connection for Drax power station – the UK’s largest biomass facility – and will also connect the Eastern Green Link 2 electrical superhighway when it starts importing clean energy from Scotland in 2029.
Drax power station seems to be growing into a large node with several gigawatts of electricity, the UK’s largest BESS, a large biomass power station and the Eastern Green Link 2 electrical superhighway which will import clean energy from Scotland from 2029.
Drax appears to be transforming from the dirty man of the UK into a Jolly Green Giant.
I can see further power stations and sources, storage devices and technology joining the party at Drax.
This Google Map shows the Drax site.
Note.
- The cooling towers can be picked out in the South-East quarter of the map.
- The site is rail and road connected, with the River Ouse nearby.
- There is a lot of space.
Surely, Drax would have a big enough space, with a high quality and high capacity electrical connection for Ørsted and Highview Power to put one of their three 200 MW/2.5 GWh batteries, that I talked about in Centrica Business Solutions And Highview Power.
What Are Offshore Hybrid Assets?
The title of this post is the same as that of a story explaining energy from National Grid.
This is the sub-heading.
Offshore Hybrid Assets or OHAs (formerly known as multi-purpose interconnectors) are a new generation of subsea technology that will connect clusters of offshore wind farms to multiple countries.
This is the first paragraph.
OHAs will help to speed up the connection of offshore wind and maximise the use of wind generation. They will also reduce the impact on local communities by reducing the amount of connection points and onshore infrastructure required to connect this clean energy to the shore.
The story goes on to discuss OHAs and how they are being developed.
It is very much a must read.
Energy In – Hydrogen And Carbon Dioxide Out
This article was inspired by this article in the Sunday Times, which is entitled ‘It’s A Slog’: Life Inside Britain’s Last Coal Power Station.
The article is about Ratcliffe-on-Soar power station, which is next to East Midlands Parkway station.
This is the first paragraph of the station’s Wikipedia entry.
Ratcliffe-on-Soar Power Station is a coal-fired power station owned and operated by Uniper at Ratcliffe-on-Soar in Nottinghamshire, England. Commissioned in 1968 by the Central Electricity Generating Board, the station has a capacity of 2,000 MW. It is the last remaining operational coal-fired power station in the UK, and is scheduled to close in September 2024.
I took these pictures of the power station in 2019.
Ratcliffe-on-Soar is the last of a number of large coal-fired power stations, that were built in the area, mainly along the River Trent.
- Rugeley – 600 MW – 1961
- Drakelow – 1630 MW – 1964
- Willington – 800 MW – 1962
- Castle Donington – 600 MW – 1958
- Ratcliffe-on-Soar – 2000 MW – 1968
- High Marnham – 1000 MW – 1959
- Cottam – 2000 MW – 1968
- West Burton – 2000 MW – 1968
Note.
- The date is the commissioning date.
- That is 10,630 MW of electricity.
- There are also a few large gas-fired power stations along the river, that are still operating.
- Both coal and gas-fired stations use the water from the River Trent for cooling.
At the mouth of the river, there is the Keadby cluster of gas-fired power stations.
- Keadby 1 – 734 MW – 1996
- Keadby 2 – 849 MW – 2023
- Keadby 3 – 910 MW – 2027
- Keadby Hydrogen – 900 MW – 2030
Note.
- The date is the commissioning date.
- That is 3,393 MW of electricity.
- Keadby 2 is the most efficient CCGT in the world.
- Keadby 3 will be fitted with carbon capture.
- Keadby 2 has been designed to be retrofitted with carbon capture.
- Keadby Hydrogen will be fuelled by zero-carbon hydrogen.
As the years progress, I can see the Keadby cluster of power stations becoming a large zero-carbon power station to back-up wind farms in the North Sea.
- Hydrogen power stations will emit no carbon dioxide.
- Carbon dioxide from all gas-fired stations will be captured.
- Some carbon dioxide will be sold on, to companies who can use it, in industries like construction, agriculture and chemical manufacture.
- The remaining carbon dioxide will be stored in depleted gas fields.
As technology improves, more carbon dioxide will be used rather than stored.
Other Power Sources In The Humberside Area
In the next few sub-sections, I will list the other major power sources in the Humberside area.
Drax Power Station
Drax power station is a shadow of its former self, when it was one of the power stations fed by the newly discovered Selby coalfield.
These days it is a 2,595 MW biomass-fired power station.
Eastern Green Link 2
Eastern Green Link 2 will be a 2 GW interconnector between Peterhead in Scotland and Drax.
It is shown in this map.
Note.
- Most of the route is underwater.
- It is funded by National Grid.
- Contracts have been signed, as I talk about in Contracts Signed For Eastern Green Link 2 Cable And Converter Stations.
- It is scheduled to be completed by 2029.
This interconnector will bring up to 2 GW of Scottish wind-generated electricity to Drax and Humberside.
Drax has the substations and other electrical gubbins to distribute the electricity efficiently to where it is needed.
2 GW could also reduce the amount of biomass used at Drax.
In the long term, if the concept of the four Eastern Green Links is successful, I could see another Eastern Green Link to Drax to replace imported biomass at Drax.
I also, don’t see why a smaller Drax can’t be run on locally-sourced biomass.
Solar Farms And Batteries Along The River Trent
As the coal-fired power stations along the River Trent are demolished, solar farm developers have moved in to develop large solar farms.
Salt End Power Station And Chemical Works
These two paragraphs from the Wikipedia entry for Salt End describes the hamlet and its power station and chemical works.
Salt End or Saltend is a hamlet in the East Riding of Yorkshire, England, in an area known as Holderness. It is situated on the north bank of the Humber Estuary just outside the Hull eastern boundary on the A1033 road. It forms part of the civil parish of Preston.
Salt End is dominated by a chemical park owned by PX group, and a gas-fired power station owned by Triton Power. Chemicals produced at Salt End include acetic acid, acetic anhydride, ammonia, bio-butanol, bio-ethanol, ethyl acetate (ETAC) and ethylene-vinyl alcohol copolymer (EVOH) with animal feed also being produced on site.
I wonder, if running the complex on hydrogen would give cost and marketing advantages.
Aldbrough Hydrogen Storage Facility
This page on the SSE Thermal web site is entitled Plans For World-Leading Hydrogen Storage Facility At Aldbrough.
This is the most significant paragraph of the page, that is definitely a must-read.
With an initial expected capacity of at least 320GWh, Aldbrough Hydrogen Storage would be significantly larger than any hydrogen storage facility in operation in the world today. The Aldbrough site is ideally located to store the low-carbon hydrogen set to be produced and used in the Humber region.
This is a hydrogen storage facility for a much wider area than Humberside.
Rough Gas Storage Facility
This is the first paragraph of the Wikipedia entry for the Rough Gas Storage Facility.
Rough is a natural gas storage facility under the North Sea off the east coast of England. It is capable of storing 100 billion cubic feet of gas, nearly double the storage capacities in operation in Great Britain in 2021.
In Wood To Optimise Hydrogen Storage For Centrica’s Rough Field, I describe Centrica’s plans to convert the Rough gas storage into a massive hydrogen storage.
The Location Of Aldbrough Gas Storage, Rough Gas Storage, Salt End And Easington Gas Terminal
This Google Map shows between Salt End and the coast.
Note.
- The river crossing the South-West corner of the map is the Humber.
- Salt End with its power station and chemical works is on the North Bank of the Humber, where the river leaves the map.
- Aldbrough Gas Storage is marked by the red arrow at the top of the map.
- Easington Gas Terminal is in the South-East corner of the map.
- According to Wikipedia, gas flows into and out of the Rough Gas Storage are managed from Easington.
Looking at the map, I feel that the following should be possible.
- The two gas storage sites could be run together.
- Salt End power station and the related chemical works could run on hydrogen.
- Salt End will always have a reliable source of hydrogen.
- This hydrogen could be green if required.
All the chemical works at Salt End, could be run on a zero-carbon basis. Would this mean premium product prices? Just like organic does?
Enter The Germans
The Germans have a huge decarbonisation problem, with all their coal-fired power stations and other industry.
Three massive projects will convert much of the country and industry to hydrogen.
- H2ercules, which is a project of OGE and RWE, will create a hydrogen network to bring hydrogen, to where it is needed.
- In Uniper To Make Wilhelmshaven German Hub For Green Hydrogen; Green Ammonia Import Terminal, I describe how Uniper are going to build a hydrogen import terminal at Wilhelmshaven.
- AquaVentus is an RWE project that will use 10.3 GW of offshore wind power in German territorial waters to create a million tonnes per year of green hydrogen.
These would appear to be three of Europe’s largest hydrogen projects, that few have ever heard of.
AquaVentus And The UK
This video shows the structure of AquaVentus.
I clipped this map from the video.
Note.
- The thick white line running North-West/South-East is the spine of AquaVentus, that delivers hydrogen to Germany.
- There is a link to Denmark.
- There appears to be an undeveloped link to Norway.
- There appears to be an undeveloped link to Peterhead in Scotland.
- There appears to be a link to just North of the Humber in England.
- Just North of the Humber are the two massive gas storage sites of Aldbrough owned by SSE and Brough owned by Centrica.
- There appear to be small ships sailing up and down the East Coast of the UK. Are these small coastal tankers, that are distributing the hydrogen to where it is needed?
In the last century, the oil industry, built a substantial oil and gas network in the North Sea.
It appears now the Germans are leading the building of a substantial hydrogen network in the North Sea.
These are my thoughts about development of the AquaVentus network.
Hydrogen Production And AquaVentus
This RWE graphic shows the layout of the wind farms feeding AquaVentus.
Note.
- There is a total of 10.3 GW.
- Is one of the 2 GW web sites on the UK-side of AquaVentus, the 3 GW Dogger Bank South wind farm, which is being developed by RWE?
- Is the 0.3 GW wind farm, RWE’s Norfolk wind farm cluster, which is also being developed by RWE?
Connecting wind farms using hydrogen pipelines to Europe, must surely mitigate the pylon opposition problem from Nimbys in the East of England.
As the AquaVentus spine pipeline could eventually connect to Peterhead, there will be other opportunities to add more hydrogen to AquaVentus.
Hydrogen Storage And AquaVentus
For AquaVentus to work efficiently and supply a large continuous flow of hydrogen to all users, there would need to be storage built into the system.
As AquaVentus is around 200 kilometres in length and natural gas pipelines can be up to 150 centimetres in diameter, don’t underestimate how much hydrogen can be stored in the pipeline system itself.
This page on the Uniper web site is entitled Green Wilhelmshaven: To New Horizons.
This is a sentence on the page.
Access to local hydrogen underground storage at the Etzel salt cavern site.
An Internet search gives the information, that Etzel gas storage could be developed to hold 1 TWh of hydrogen.
That would be enough hydrogen to supply 10 GW for a hundred hours.
Note that the UK branch of AquaVentus reaches the UK, just to the South of the massive hydrogen storage facilities at Aldbrough and Rough.
It would appear that both Germany and the UK are connected to AquaVentus through substantial storage.
I am certain, that all country connections to AquaVentus will have substantial storage at the country’s hydrogen terminal.
AquaDuctus
This would appear to be the first part of the AquaVentus network and has its own web site.
The web site is entitled Nucleus Of A Offshore Hydrogen Backbone.
These are the first two paragraphs.
The project partners are focusing on a scalable, demand-driven infrastructure: By 2030, AquaDuctus will connect the first large hydrogen wind farm site, SEN-1, with a generation capacity of approximately one gigawatt. SEN-1 is located in the German EEZ in the northwest of Helgoland. The pipeline will transport at a length of approx. 200 km green hydrogen produced from offshore wind to the German mainland and from there to European consumers via the onshore hydrogen infrastructure.
In the next project stage, AquaDuctus will be extended to the remote areas of the German exclusive economic zone towards the tip of the so-called duck’s bill. By that, additional future hydrogen wind farm sites will be connected. Along its way AquaDuctus will provide interconnection points with the opportunity for linking of adjacent national offshore hydrogen infrastructures originating from Denmark, Norway, the Netherlands, Belgium and United Kingdom which opens the door for Europe-wide offshore hydrogen transport by pipeline.
There is also an interactive map, that gives more details.
This paragraph explains, why the Germans have chosen to bring the energy ashore using hydrogen, rather than traditional cables.
Recent studies show that offshore hydrogen production and transport via pipelines is faster, cheaper, and more environmentally friendly than onshore electrolysis with a corresponding connection of offshore wind turbines via power cables. The German federal government has also recognized this advantage and has clearly expressed its intention to promote offshore hydrogen production in the North Sea.
I suspect, that some UK offshore wind farms will use the same techniques.
Hydrogen Production For The UK
Electrolysers will probably be built along the East Coast between Peterhead and Humberside and these will feed hydrogen into the network.
- Some electrolysers will be offshore and others onshore.
- Turning off windfarms will become a thing of the past, as all surplus electricity will be used to make hydrogen for the UK or export to Europe.
- Until needed the hydrogen will be stored in Albrough and Rough.
Backup for wind farms, will be provided using hydrogen-fired power stations like Keadby Hydrogen power station.
Financial Implications
I reported on Rishi Sunak’s Manifesto Speech, which he made on June 11th. This is an extract
This document on the Policy Mogul web site is entitled Rishi Sunak – Conservative Party Manifesto Speech – Jun 11.
These are three paragraphs from the speech.
We don’t just need military and border security. As Putin’s invasion of Ukraine has shown, we need energy security too. It is only by having reliable, home-grown sources of energy that we can deny dictators the ability to send our bills soaring. So, in our approach to energy policy we will put security and your family finances ahead of unaffordable eco zealotry.
Unlike Labour we don’t believe that we will achieve that energy security via a state-controlled energy company that doesn’t in fact produce any energy. That will only increase costs, and as Penny said on Friday there’s only one thing that GB in Starmer and Miliband’s GB Energy stands for, and that’s giant bills.
Our clear plan is to achieve energy security through new gas-powered stations, trebling our offshore wind capacity and by having new fleets of small modular reactors. These will make the UK a net exporter of electricity, giving us greater energy independence and security from the aggressive actions of dictators . Now let me just reiterate that, with our plan, we will produce enough electricity to both meet our domestic needs and export to our neighbours. Look at that. A clear, Conservative plan not only generating security, but also prosperity for our country.
I can’t remember any reports about an energy security policy, which he outlined in the last paragraph of my extract from his speech.
He also said we would have sufficient electricity to export to our neighbours. As I said earlier some of this energy will be in the form of hydrogen, which has been created by offshore electrolysers.
If we are exporting electricity and hydrogen to Europe, this is likely to have three effects.
- An improvement in Europe’s energy security.
- H2ercules will improve and decarbonise German industry, using UK hydrogen.
- The finances of UK plc will improve.
It looks like there would be winners all round.
Rishi Sunak had the cards and he played them very badly.
It is now up to Keir Starmer, Great British Energy and Jürgen Maier to play those cards to link the energy systems of the UK and Germany to ensure security and prosperity for Europe.
Where’s The Plan, Rishi?
In RWE Goes For An Additional 10 GW Of Offshore Wind In UK Waters In 2030, I detailed how RWE intended to add an extra 10 GW of offshore wind to the seas around the UK.
As our current offshore wind capacity is around 15 GW, another 10 GW would surely be very welcome.
My post also outlined H2ercules, which is Germany’s massive project to create a hydrogen network to bring hydrogen to Southern Germany.
I also gave details of the hydrogen hub at Wilhelmshaven, which is being built by Uniper to feed H2ercules with green hydrogen from around the world.
I believe that some of this hydrogen for H2ercules will take a short trip across the North Sea from UK waters, after being created by offshore electrolysers.
Rishi Sunak’s Manifesto Speech – June 11
I also reported on Rishi Sunak’s Manifesto Speech, which he made on June 11th. This is an extract
This document on the Policy Mogul web site is entitled Rishi Sunak – Conservative Party Manifesto Speech – Jun 11.

A clear, Conservative plan not only generating security, but also prosperity for our country.
It is now nine days since Rishi made that speech and I can’t remember any reports about an energy security policy, which he outlined in the last paragraph of my extract from his speech.
He particularly mentioned.
- New gas-powered stations
- Trebling our offshore wind capacity
- Having new fleets of small modular reactors.
He also said we would have sufficient electricity to export to our neighbours. As I said earlier some of this energy will be in the form of hydrogen, which has been created by offshore electrolysers.

- The finances of UK plc will improve.
It looks like there will be winners all round.
Rishi also said this, in his speech.
As Putin’s invasion of Ukraine has shown, we need energy security too.
The gas-powered stations, offshore wind farms and the fleets of small modular reactors, will be part of the equation.
But I believe, we need three other components to complete our energy security.
- The upgrading of the National Grid.
- The building of four x 2 GW interconnectors between Scotland and Eastern England.
- Large amounts of energy storage.
Note.
- The Great Grid Upgrade and the four x 2 GW interconnectors are being planned.
- In Huge Boost To UK Supply Chain As National Grid Launches The Great Grid Partnership With Seven New Industry Partners, All United In The Drive To Deliver The Great Grid Upgrade, I describe how National Grid has setup the Great Grid Partnership to deliver the Great Grid Upgrade.
- In UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security, I describe how the big boys do a deal with Highview Power to create affordable batteries for the UK and the world.
- In Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, I describe how the very large Swardeston BESS is to be built near Norwich.
- In Mercia Power Response & RheEnergise Working Together To Build Long Duration Energy Storage Projects In The UK, I describe another UK-developed long duration energy storage system, which is now being planned.
- In 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, I describe National Grid’s projects in the East of England.
- In UK ESO Unveils GBP 58 Billion Grid Investment Plan To Reach 86 GW of Offshore Wind By 2035, I show how we’re not that far away from 86 GW by 2035.
- In 400k For National Grid Innovation Projects As Part Of Ofgem Fund To Help Shape Britain’s Net Zero Transition, I describe how National Grid is using innovation to help target net-zero by 2035.
- In Iberdrola Preparing Two East Anglia Offshore Wind Projects For UK’s Sixth CfD Round, I describe how Iberdrola is getting 1.7 GW ready for commissioning in 2026.
- In National Grid To Accelerate Up To 20GW Of Grid Connections Across Its Transmission And Distribution Networks, I describe how National Grid are accelerating the development of the electricity networks. 10 GW of battery storage is a collateral benefit.
These ten projects, most of which are financed and/or underway, would appear to be good foundations, on which to build the Great Grid Upgrade.
It looks to me, that National Grid, RWE, Centrica, Iberdrola and others, by just doing what comes naturally have offered the next government a road to a future.
It will be interesting, what gets said before the election.
UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security
The title of this post, is the same as that of this news item from Highview Power.
This is the sub-heading.
Highview Power kickstarts its multi-billion pound renewable energy programme to accelerate the UK’s transition to net zero in Carrington, Manchester.
These three paragraphs outline the investment.
Highview Power has secured the backing of the UK Infrastructure Bank and the energy industry leader Centrica with a £300 million investment for the first commercial-scale liquid air energy storage (LAES) plant in the UK.
The £300 million funding round was led by the UK Infrastructure Bank (UKIB) and the British multinational energy and services company Centrica, alongside a syndicate of investors including Rio Tinto, Goldman Sachs, KIRKBI and Mosaic Capital.
The investment will enable the construction of one of the world’s largest long duration energy storage (LDES) facilities in Carrington, Manchester, using Highview Power’s proprietary LAES technology. Once complete, it will have a storage capacity of 300 MWh and an output power of 50 MWs per hour for six hours. Construction will begin on the site immediately, with the facility operational in early 2026, supporting over 700 jobs in construction and the supply chain.
Note.
- The backers are of a high quality.
- The Carrington LDES appears to be a 50 MW/300 MWh battery.
It finally looks like Highview Power is on its way.
These are my thoughts on the rest of news item.
Centrica’s Involvement
This paragraph talks about Centrica’s involvement.
Energy leader Centrica comes on board as Highview Power’s strategic partner and a key player in the UK’s energy transition, supporting Carrington and the accelerated roll-out of the technology in the UK through a £70 million investment. The programme will set the bar for storage energy systems around the world, positioning the UK as the global leader in energy storage and flexibility.
I suspect that Centrica have an application in mind.
In Centrica Business Solutions Begins Work On 20MW Hydrogen-Ready Peaker In Redditch, I talk about how Centrica is updating an old peaker plant.
In the related post I refer to this news item from Centrica Business Systems.
This paragraph in the Centrica Business Systems news item, outlines Centrica’s plans.
The Redditch peaking plant is part of Centrica’s plans to deliver around 1GW of flexible energy assets, that includes the redevelopment of several legacy-owned power stations, including the transformation of the former Brigg Power Station in Lincolnshire into a battery storage asset and the first plant in the UK to be part fuelled by hydrogen.
As Redditch power station is only 20 MW, Centrica could be thinking of around fifty assets of a similar size.
It seems to me, that some of these assets could be Highview Power’s LDES batteries of an appropriate size. They may even be paired with a wind or solar farm.
Larger Systems
Highview Power’s news item, also has this paragraph.
Highview Power will now also commence planning on the next four larger scale 2.5 GWh facilities (with a total anticipated investment of £3 billion). Located at strategic sites across the UK, these will ensure a fast roll-out of the technology to align with UK LDES support mechanisms and enable the ESO’s Future Energy Scenario Plans.
Elsewhere on their web site, Highview Power say this about their 2.5 GWh facilities.
Highview Power’s next projects will be located in Scotland and the North East and each will be 200MW/2.5GWh capacity. These will be located on the national transmission network where the wind is being generated and therefore will enable these regions to unleash their untapped renewable energy potential and store excess wind power at scale.
So will the four larger systems have a 200MW/2.5GWh capacity?
They could, but 200 MW may not be an appropriate output for the location. Or a longer duration may be needed.
Highview Power’s design gives the flexibility to design a system, that meets each application.
Working With National Grid
Highview Power’s news item, also has this sentence.
Highview Power’s technology will also provide stability services to the National Grid, which will allow for the long-term replacement of fossil fuel-based power plants for system support.
Highview Power’s technology is also an alternative to Battery Energy Storage Systems (BESS) of a similar capacity.
How does Highview Power’s technology compare with the best lithium-ion systems on price, performance and reliability?
Curtailment Of Wind Farms
Highview Power’s news item, also has these two paragraphs.
This storage will help reduce curtailment costs – which is significant as Britain spent £800m in 2023 to turn off wind farms.
Highview Power aims to accelerate the roll-out of its larger facilities across the UK by 2035 in line with one of National Grid’s target scenario forecasts of a 2 GW requirement from LAES, which would represent nearly 20% of the UK’s long duration energy storage needs. By capturing and storing excess renewable energy, which is now the cheapest form of electricity, storage can help keep energy costs from spiralling, and power Britain’s homes with 24/7 renewable clean energy.
I can see several wind farms, that are regularly curtailed would have a Highview Power battery installed at their onshore substation.
Receently, I wrote Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, which described how Ørsted are installing a 300 MW/600 MWh Battery Energy Storage Systems (BESS) at Swardeston substation, where Hornsea Three connects to the grid.
I would suspect that the purpose of the battery is to avoid turning off the wind farm.
Would a Highview Power battery be better value?
What’s In It For Rio Tinto?
I can understand, why most companies are investing, but Rio Tinto are a mining company. My only thought is that they have a lot of redundant holes in the ground, that cost them a lot of money and by the use of Highview Power’s technology, they can be turned into productive assets.
Collateral Benefits
Highview Power’s news item, also has this paragraph.
Beyond contributing to the UK’s energy security by reducing the intermittency of renewables, Highview Power’s infrastructure programme will make a major contribution to the UK economy, requiring in excess of £9 billion investment in energy storage infrastructure over the next 10 years – with the potential to support over 6,000 jobs and generate billions of pounds in value add to the economy. It will also contribute materially to increasing utilisation of green energy generation, reducing energy bills for consumers and providing significantly improved energy stability and security.
If Highview Power can do that for the UK, what can it do for other countries?
No wonder companies of the quality of Centrica, Rio Tinto and Goldman Sachs are investing.
Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Orsted’s huge facility in Norfolk will store energy generated by its offshore wind farm
These three paragraphs give more details of the project.
The world’s largest developer of offshore wind farms is planning to build a vast battery storage facility near Norwich.
Orsted will install the energy storage system, which will be one of the largest in Europe, on the same site as the onshore converter station for its Hornsea 3 wind farm in Swardeston, Norfolk.
The project will store energy generated by Hornsea 3 when weather conditions are windy and when electricity supply exceeds demand so that it can be discharged later to help to balance the nation’s electricity grid.
Note.
- There is also a visualisation and a map.
- Tesla batteries will be used.
- The The battery will have an output of 300 MW, with a capacity of 600 MWh. So it is another two-hour BESS.
- It should be operational in 2026.
- The battery is on a 35-acre site.
- Cost is given as £8.5 billion, but that would appear to include the 2852 MW Hornsea 3 wind farm.
The BBC is reporting that local residents are worried about fire safety.
I have some thoughts of my own.
The Location Of The Swardeston Substation
This Google Map shows the location of the Swardeston substation, which will also host the Swardeston BESS.
Note.
- The East-West road is the A 47 Norwich by-pass.
- Norwich is to the North of the by-pass.
- Just to the left-centre of the map, the main A 140 road runs between Norwich and Ipswich, which has a junction with the A 47.
- The A 140 passes through the village of Dunston, which is to the East of the National Grid sibstation, which will host the connection to the Hornsea Three wind farm.
This second Google Map shows the A 140 in detail from the junction to the A 47 to the Swardeston substation.
Note.
- The Swardeston substation is on a substantial site.
- The Norwich to Tilbury transmission line will have its Northern end at Swardeston substation.
- Once the infrastructure is complete at Swardeston substation, Hornsea Three wind farm will be connected to the electricity infrastructure around London.
There would appear to be plenty of space at the site for all National Grid’s plans.
Capital Cost Compared To Big Nuclear
Hornsea Three is a 2852 MW wind farm, that will cost with the battery and a few extras £8.5 billion or around around £ 3 billion per gigawatt.
Hinckley Point C on the other hand will cost between £ 31-35 billion or £ 9.5-10.7 billion per gigawatt.
Conclusion
National Grid would appear to be using a BESS at Swardeston substation to improve the reliability and integrity of the Hornsea Three wind farm.
How many other big batteries will be placed, where large wind farms connect to the National Grid?
As an Electrical and Control Engineer, I certainly, believe that energy storage at major substations, is a proven way to improve the grid.
Do RWE Have A Comprehensive Hydrogen Plan For Germany?
What is interesting me, is what Germany company; RWE is up to. They are one of the largest UK electricity producers.
In December 2023, they probably paid a low price, for the rights for 3 x 1.4 GW wind farms about 50 km off North-East Norfolk from in-trouble Swedish company; Vattenfall and have signed contracts to build them fairly fast.
In March 2024, wrote about the purchase in RWE And Vattenfall Complete Multi-Gigawatt Offshore Wind Transaction In UK.
Over the last couple of years, I have written several posts about these three wind farms.
March 2023 – Vattenfall Selects Norfolk Offshore Wind Zone O&M Base
November 2023 – Aker Solutions Gets Vattenfall Nod To Start Norfolk Vanguard West Offshore Platform
December 2023 – SeAH To Deliver Monopiles For Vattenfall’s 2.8 GW Norfolk Vanguard Offshore Wind Project
Then in July 2023, I wrote Vattenfall Stops Developing Major Wind Farm Offshore UK, Will Review Entire 4.2 GW Zone
Note.
- There does appear to be a bit of a mix-up at Vattenfall, judging by the dates of the reports.Only, one wind farm has a Contract for Difference.
- It is expected that the other two will be awarded contracts in Round 6, which should be by Summer 2024.
In December 2023, I then wrote RWE Acquires 4.2-Gigawatt UK Offshore Wind Development Portfolio From Vattenfall.
It appears that RWE paid £963 million for the three wind farms.
I suspect too, they paid for all the work Vattenfall had done.
This transaction will give RWE 4.2 GW of electricity in an area with very bad connections to the National Grid and the Norfolk Nimbies will fight the building of more pylons.
So have the Germans bought a pup?
I don’t think so!
Where Is Wilhemshaven?
This Google Map shows the location of Wilhemshaven.
Note.
- Heligoland is the island at the top of the map.
- The Germans call this area the Wdden Sea.
- The estuaries lead to Wilhelmshaven and Bremerhaven.
- Cuxhaven is the port for Heligoland, which is connected to Hamburg by hydrogen trains.
This second map shows between Bremerhaven and Wilhelmshaven.
Note.
- Wilhelmshaven is to the West.
- Bremerhaven is in the East.
- The River Weser runs North-South past Bremerhaven.
I’ve explored the area by both car and train and it is certainly worth a visit.
The Wilhemshaven Hydrogen Import Terminal
German energy company; Uniper is building a hydrogen import terminal at Wilhemshaven to feed German industry with hydrogen from places like Australia, Namibia and the Middle East. I wrote about this hydrogen import terminal in Uniper To Make Wilhelmshaven German Hub For Green Hydrogen; Green Ammonia Import Terminal.
I suspect RWE could build a giant offshore electrolyser close to the Norfolk wind farms and the hydrogen will be exported by tanker or pipeline to Germany or to anybody else who pays the right price.
All this infrastructure will be installed and serviced from Great Yarmouth, so we’re not out of the deal.
Dogger Bank South Wind Farm
To make matters better, RWE have also signed to develop the 3 GW Dogger Bank South wind farm.
This could have another giant electrolyser to feed German companies. The wind farm will not need an electricity connection to the shore.
The Germans appear to be taking the hydrogen route to bringing electricity ashore.
Energy Security
Surely, a short trip across the North Sea, rather than a long trip from Australia will be much more secure and on my many trips between the Haven Ports and The Netherlands, I haven’t yet seen any armed Houthi pirates.
RWE And Hydrogen
On this page on their web site, RWE has a lot on hydrogen.
Very Interesting!
H2ercules
This web site describes H2ercules.
The goal of the H2ercules initiative is to create the heart of a super-sized hydrogen infrastructure for Germany by 2030. To make this happen, RWE, OGE and, prospectively, other partners are working across various steps of the value chain to enable a swift supply of hydrogen from the north of Germany to consumers in the southern and western areas of the country. In addition to producing hydrogen at a gigawatt scale, the plan is also to open up import routes for green hydrogen. The transport process will involve a pipeline network of about 1,500 km, most of which will consist of converted gas pipelines.
Where’s the UK’s H2ercules?
Conclusion
The Germans have got there first and will be buying up all of our hydrogen to feed H2ercules.
Ameresco And Envision Energy To Deploy 624MWh UK BESS For Atlantic Green
The title of this post, is the same as that of this article on Energy Storage News.
These three paragraphs describe the project.
Developer-operator Atlantic Green has enlisted system integrator Ameresco and clean energy manufacturer Envision Energy for a 300MW/624MWh BESS project in the UK.
The Cellarhead battery energy storage system (BESS) project will be connected to National Grid’s Cellarhead substation in the West Midlands and have a maximum energy capacity of 624MWh. Construction is expected to begin this year, with final connection to the grid slated for the end of 2026.
The deal between the parties is worth £196.5 million (US$250 million). Ameresco will build the project via an engineering, procurement and construction (EPC) and operation & maintenance (O&M) agreement while Envision Energy will supply the BESS units.
Note.
- It is another battery, that can provide full power for two hours.
- It is another battery, that is located near to one of National Grid’s substations.
As batteries seem to be made by different companies, it looks to me, that National Grid are possibly checking out, which batteries are best.
RWE And the Norfolk Wind Farms
In March 2024, I wrote RWE And Vattenfall Complete Multi-Gigawatt Offshore Wind Transaction In UK, which described how Vattenfall had sold 4.2 GW of offshore wind farms, situated off North-East Norfolk to RWE.
This map from RWE shows the wind farms.
Note.
- The Norfolk Zone consists of three wind farms; Norfolk Vanguard West, Norfolk Boreas and Norfolk Vanguard East.
- The three wind farms are 1.4 GW fixed-foundation wind farms.
- In Vattenfall Selects Norfolk Offshore Wind Zone O&M Base, I describe how the Port of Great Yarmouth had been selected as the O & M base.
- Great Yarmouth and nearby Lowestoft are both ports, with a long history of supporting shipbuilding and offshore engineering.
The wind farms and the operational port are all close together, which probably makes things convenient.
So why did Vattenfall sell the development rights of the three wind farms to RWE?
Too Much Wind?
East Anglia is fringed with wind farms all the way between the Wash and the Thames Estuary.
- Lincs – 270 MW
- Lynn and Inner Dowsing – 194 MW
- Race Bank – 580 MW
- Triton Knoll – 857 MW
- Sheringham Shoal – 317 MW
- Dudgeon – 402 MW
- Hornsea 3 – 2852 MW *
- Scroby Sands – 60 MW
- East Anglia One North – 800 MW *
- East Anglia Two – 900 MW *
- East Anglia Three – 1372 MW *
- Greater Gabbard – 504 MW
- Galloper – 353 MW
- Five Estuaries – 353 MW *
- North Falls – 504 MW *
- Gunfleet Sands – 172 MW
- London Array – 630 MW
Note.
- Wind farms marked with an * are under development or under construction.
- There is 4339 MW of operational wind farms between the Wash and the Thames Estuary.
- An extra 6781 MW is also under development.
If all goes well, East Anglia will have over 11 GW of operational wind farms or over 15 GW, if the three Norfolk wind farms are built.
East Anglia is noted more for its agriculture and not for its heavy industries consuming large amounts of electricity, so did Vattenfall decide, that there would be difficulties selling the electricity?
East Anglia’s Nimbies
East Anglia’s Nimbies seem to have started a campaign against new overground cables and all these new wind farms will need a large capacity increase between the main substations of the National Grid and the coast.
So did the extra costs of burying the cable make Vattenfall think twice about developing these wind farms?
East Anglia and Kent’s Interconnectors
East Anglia and Kent already has several interconnectors to Europe
- Viking Link – Bicker Fen and Jutland – 1.4 GW
- LionLink – Suffolk and the Netherlands – 1.8 GW – In Planning
- Nautilus – Suffolk or Isle of Grain and Belgium – 1.4 GW – In Planning
- BritNed – Isle of Grain and Maasvlakte – 1.0 GW
- NeuConnect – Isle of Grain and Wilhelmshaven – 1.4 GW – Under Construction
- GridLink Interconnector – Kingsnorth and Warande – 1.4 GW – Proposed
- HVDC Cross-Channel – Sellinge and Bonningues-lès-Calais – 2.0 GW
- ElecLink – Folkestone and Peuplingues – 1.0 GW
- Nemo Link – Richborough and Zeebrugge – 1.0 GW
Note.
- Five interconnectors with a capacity of 6.4 GW.
- A further four interconnectors with a capacity of 6 GW are on their way.
At 12.4 GW, the future capacity of the interconnectors between South-East England and Europe, is nor far short of South-East English wind power.
There are also two gas pipelines from the Bacton gas terminal between Cromer and Great Yarmouth to Europe.
The Wikipedia entry for the Bacton gas terminal gives these descriptions of the two gas pipelines.
Interconnector UK – This can import gas from, or export gas to, Zeebrugge, Belgium via a 235 km pipeline operating at up to 147 bar. There is a 30-inch direct access line from the SEAL pipeline. The Interconnector was commissioned in 1998.
BBL (Bacton–Balgzand line) – This receives gas from the compressor station in Anna Paulowna in the Netherlands. The BBL Pipeline is 235 km long and was commissioned in December 2006.
It would appear that East Anglia and Kent are well connected to the Benelux countries, with both electricity and gas links, but with the exception of the Viking Link, there is no connection to the Scandinavian countries.
Did this lack of connection to Sweden make convincing the Swedish government, reluctant to support Vattenfall in their plans?
Bringing The Energy From The Norfolk Wind Farms To Market
It looks to me, that distributing up to 4.2 GW from the Norfolk wind farms will not be a simple exercise.
- Other wind farms like the 2852 MW Hornsea 3 wind farm, may need a grid connection on the North Norfolk coast.
- The Nimbies will not like a South-Western route to the National Grid at the West of Norwich.
- An interconnector to Denmark or Germany from North Norfolk would probably help.
But at least there are two gas pipelines to Belgium and the Netherlands.
RWE, who now own the rights to the Norfolk wind farms, have a large amount of interests in the UK.
- RWE are the largest power producer in the UK.
- They supply 15 % of UK electricity.
- They have interest in twelve offshore wind farms in the UK. When fully-developed, they will have a capacity of almost 12 GW.
- RWE are developing the Pembroke Net Zero Centre, which includes a hydrogen electrolyser.
RWE expects to invest up to £15 billion in the UK by 2030 in new and existing green technologies and infrastructure as part of this.
Could this be RWE’s plan?
As the Norfolk wind farms are badly placed to provide electricity to the UK grid could RWE have decided to use the three Norfolk wind farms to produce hydrogen instead.
- The electrolyser could be placed onshore or offshore.
- If placed onshore, it could be placed near to the Bacton gas terminal.
- There are even depleted gas fields, where hydrogen could be stored.
How will the hydrogen be distributed and/or used?
It could be delivered by tanker ship or tanker truck to anyone who needs it.
In Developing A Rural Hydrogen Network, I describe how a rural hydrogen network could be developed, that decarbonises the countryside.
There are three major gas pipelines leading away from the Bacton gas terminal.
- The connection to the UK gas network.
- Interconnector UK to Belgium.
- BBL to The Netherlands.
These pipelines could be used to distribute hydrogen as a hydrogen blend with natural gas.
In UK – Hydrogen To Be Added To Britain’s Gas Supply By 2025, I describe the effects of adding hydrogen to the UK’s natural gas network.
