Global Offshore Wind To Top 520 GW By 2040, Floating Wind To Play Major Role – Rystad Energy

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

This is the sub-heading.

According to Rystad Energy, global offshore wind capacity will surpass 520 GW by 2040, with floating wind installations nearing 90 GW by that time

These are the first three paragraphs.

In 2023, the offshore wind sector saw a seven per cent increase in new capacity additions compared to the previous year, said Rystad Energy. This momentum is expected to accelerate this year, with new capacity additions expected to grow by nine per cent to over 11 GW by the end of the year.

By 2040, Europe is expected to account for more than 70 per cent of global floating wind installations. Although some project delays beyond 2030 are anticipated, there will likely be a strong push to accelerate deployment, according to Rystad Energy.

As a result, floating wind capacity is projected to approach 90 GW by 2040, led by the UK, France, and Portugal, with Asia (excluding mainland China) expected to account for 20 per cent of global installations.

Note, that Rystad Energy is an independent energy research and business intelligence company headquartered in Oslo, Norway.

Implications For Energy Storage

In Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, I talk about how the 2.9 GW Hornsea Three wind farm will have a connection to the grid, that incorporates a 300 MW/600 MWh battery.

With 520 GW of offshore wind to be installed by 2040, I suspect that energy storage companies and funds will do well.

If the 520 GW of offshore wind were fitted with batteries like the 2.9 GW Hornsea Three wind farm, there would be a need for around 60 GW of battery output, with a capacity of around 120 GWh.

I doubt, there would be enough lithium for all those batteries.

Some countries like Norway, the United States, Australia, France, Spain, Japan, India, China and others will be able to develop large pumped storage hydroelectricity systems, but others will have to rely on newer, developing technologies.

The UK will be well-placed with around 80 GWh of pumped storage hydroelectricity under development and several promising developing storage technologies.

‘World’s First’ O&M Campaign Using Heavy-Lift Cargo Drones Underway At Dutch Offshore Wind Farm

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

This is the sub-heading.

Ørsted has deployed heavy-lift cargo drones (HLCDs) for maintenance work at the Borssele 1&2 offshore wind farm in the Netherlands. This is the first time heavy-lift cargo drones are being used in an operational campaign, according to the company which tested the concept in 2023 at its Hornsea One offshore wind farm in the UK.

These are the first two paragraphs.

At the 752 MW Dutch offshore wind farm that has been in operation since 2020, the 70-kilogram drones will transport cargo of up to 100 kilograms from a vessel to all 94 wind turbines. The campaign now underway at Borssele 1&2 is being performed to update some critical evacuation and safety equipment in each of the turbines.

A drone can complete a task that typically takes several hours in minutes, according to Ørsted.

Note.

  1. The article claims, a lot of time is saved.
  2. I suspect we’ll be seeing the use of drones for multiple deliveries, a lot more in the future.

I like the concept, where deliveries to a number of sites are made by drone, rather than in a traditional way perhaps by a ship or truck with a crane.

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.

  1. The date is the commissioning date.
  2. That is 10,630 MW of electricity.
  3. There are also a few large gas-fired power stations along the river, that are still operating.
  4. 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.

  1. The date is the commissioning date.
  2. That is 3,393 MW of electricity.
  3. Keadby 2 is the most efficient CCGT in the world.
  4. Keadby 3 will be fitted with carbon capture.
  5. Keadby 2 has been designed to be retrofitted with carbon capture.
  6. 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.

  1. Most of the route is underwater.
  2. It is funded by National Grid.
  3. Contracts have been signed, as I talk about in Contracts Signed For Eastern Green Link 2 Cable And Converter Stations.
  4. 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.

  1. The river crossing the South-West corner of the map is the Humber.
  2. Salt End with its power station and chemical works is on the North Bank of the Humber, where the river leaves the map.
  3. Aldbrough Gas Storage is marked by the red arrow at the top of the map.
  4. Easington Gas Terminal is in the South-East corner of the map.
  5. 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.

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.

  1. The thick white line running North-West/South-East is the spine of AquaVentus, that delivers hydrogen to Germany.
  2. There is a link to Denmark.
  3. There appears to be an undeveloped link to Norway.
  4. There appears to be an undeveloped  link to Peterhead in Scotland.
  5. There appears to be a link to just North of the Humber in England.
  6. Just North of the Humber are the two massive gas storage sites of Aldbrough owned by SSE and Brough owned by Centrica.
  7. 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.

  1. There is a total of 10.3 GW.
  2. 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?
  3. 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.

Site Investigations Underway At RWE’s Three Norfolk Offshore Wind Project Sites

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

This is the sub-heading.

RWE has kicked off geophysical and geotechnical site investigations at the Norfolk Boreas, Norfolk Vanguard East, and Norfolk Vanguard West offshore wind project sites in the UK, rights to which the German company acquired from Vattenfall earlier this year.

All three projects in RWE’s 4.14 GW wind farm off the Norfolk coast, at last seem to be making progress.

According to the Wikipedia entry for the List Of Offshore Wind Farms In The United Kingdom, this is the last status.

Norfolk Boreas

Owner: RWE

Turbines: Vestas

Status: Contract for Difference – Round 4

Commissioning Date: 2027

Norfolk Vanguard East

Owner: RWE

Turbines: Vestas

Status: Early Planning

Commissioning Date: Before 2030

Norfolk Vanguard West

Owner: RWE

Turbines: Vestas V236-15.0 MW

Status: Early Planning

Commissioning Date: Before 2030

Note.

  1. All three Norfolk wind arms, will be using Vestas turbines.
  2. The data for Norfolk Vanguard West shows that Vestas V236-15.0 MW turbines will be used.
  3. In SeAH To Deliver Monopiles For Vattenfall’s 2.8 GW Norfolk Vanguard Offshore Wind Project, I discussed the monopiles for the Norfolk wind farms. Will these be standardised across the Norfolk wind farms?
  4. In RWE Orders 15 MW Nordseecluster Offshore Wind Turbines At Vestas, I speculated that RWE had standardised on these large turbines for their North Sea wind farms, which would surely be a sensible action to take.

Using the same large turbines and monopiles for a number of wind farms, will surely give advantages in manufacture, installation, operation and and servicing for RWE, SeAH Wind and Vestas.

The finances should also be more beneficial.

These are my thoughts.

Will The Norfolk Wind Farms Produce Hydrogen For Germany?

Consider.

  • As Hornsea 4 wind farm makes landfall in Norfolk, Norfolk should have enough renewable electricity.
  • The Norfolk Nimbies will object to more electricity transmission lines across Norfolk.
  • H2ercules, which is the large German hydrogen network will need lots of green hydrogen.
  • Wilhelmshaven, which will be the main hydrogen feed point for H2ercules, is just across the North Sea at Wilhelmshaven.
  • There are no Houthis roaming the North Sea.
  • Hydrogen could be transported from the Norfolk wind farms to Wilhelmshaven by pipeline or coastal tanker.
  • German companies are building the Norfolk wind farms.

I believe that there is a good chance, that the Norfolk wind farms will produce hydrogen for Germany.

This will have the following benefits.

  • Germany will get the hydrogen it needs.
  • The hydrogen link will improve energy security in Europe.
  • The UK government will receive a nice cash flow.

The only losers will be the dictators, who supply Europe with energy.

Centrica Business Solutions And Highview Power

Centrica Business Solutions is one of Centrica’s business units.

It has its own web page, with this sub heading.

Helping Organisations Balance Planet And Profit

This is followed by this mission statement.

Centrica Business Solutions helps organisations to balance the demands of planet and profit, by delivering integrated energy solutions that help you save money and become a sustainable business.

Several pictures show some of the solutions, that Centrica Business Solutions can provide.

Centrica Business Solutions In Numbers

These numbers are given about the customers of Centrica Business Solutions.

  • Customer Sites Globally – 7000
  • Solar PV Installations Delivered Worldwide – 16,380+
  • Solar PV Installations Delivered Power – 240 MW
  • CHP Units Operated And Maintained Globally – 700 MW+
  • Energy Data Points Collected Each Month Globally  – 29 billion

Theses are large numbers.

How Would Centrica Business Solutions Use Highview Power’s Batteries?

The obvious use of Highview Power’s batteries is to connect them between a solar or wind farm and the grid, for when the sun isn’t shining or when the wind isn’t blowing.

Currently, there are three sizes of Highview Power batteries, either working on under development.

5MW/15 MWh

This is the demonstration system, which is described on this page of the Highview web site.

Surely, if a system of this size is very useful for Viridor, there may be other applications and customers out there.

This system will provide 5 MW for three hours.

50MW/300MWh

This is the Carrington system, which is described on this page of the Highview web site.

The Highview web site says this about output potential and connectivity.

The facility will store enough clean, renewable energy to serve the needs of 480,000 homes, as well as providing essential grid stabilisation services. The site will use existing substation and transmission infrastructure.

This system will provide 50 MW for six hours.

200MW/2.5GWh

This is the larger system for Scotland and the North East, which is under development and described on this page of the Highview web site.

The Highview web site says this about output their use.

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.

This system will provide 200 MW for 12.5 hours.

In Rio Tinto Punts On British Start-Up To Plug Renewables Gap, I said this.

In Britain, Highview hopes to be putting four 2.5-gigawatt assets into planning this year – one in Scotland, three with Orsted in England.

This sentence was originally published in this article on the Australian Financial Review.

I believe that Centrica could find applications for all three sizes of Highview’s batteries.

Suppose, though Centrica find that an application needs say a 100 MW/1 GWh battery.

From the mathematics, I did at ICI in the 1970s, when looking at the scaling of chemical plants, I believe that Highview’s battery design could be scalable, by just using appropriately-sized turbomachinery, matched to the right number of tanks.

So the customer would get the battery size they needed!

How Much Electricity Could One Of Highview’s Batteries Store?

This image shows large LNG tanks at Milford Haven.

In Could A Highview Power CRYOBattery Use A LNG Tank For Liquid Air Storage?, I did a rough calculation and found that the largest LNG tanks could hold enough liquid air, that would be the equivalent of around one GWh.

So the image above could be a 5 GWh battery.

This image clipped from Highview’s web site, shows large tanks for liquified gas storage.

With tanks like these, Highview could be building batteries with storage to rival the smaller pumped storage hydroelectric power stations.

In Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, I talked about how Ørsted were planning the Swardeston BESS, where the 2852 MW Hornsea Three wind farm connects to the grid.

The chosen battery will be from Tessla with an output of 300 MW and a capacity of 600 MWh.

I suspect Ørsted couldn’t wait for Highview, but circumstances might have changed now, with the financing deal for the Carrington battery!

Are Combined Heat And Power Units And Highview’s Batteries Interchangeable And Complementary Technologies?

According to the Centrica Business Systems web site, they have deployed over 700 MW of CHP systems globally.

I wonder how many of these systems could have used a standard Highview battery?

Perhaps, Centrica Business Systems have done a survey and found that it could be quite a few.

So, perhaps if Centrica Business Systems had access to Highview’s technology, it would increase their sales.

In addition how many of Centrica Business Systems existing CHP systems, would be improved with the addition of a Highview battery?

It appears to me, that if Centrica Business Systems were to develop a series of standard solutions based on Highview’s technology, they could substantially increase their sales.

What Could Centrica Business Systems Do For Highview Power?

Centrica Business Systems could probably develop several standard applications with Hoghview’s technology, which would be to the benefit of both companies.

But, I believe that as Centrica Business Systems are supporting large number of systems globally, that they are in a good place to help develop and possibly run Highview Power’s support network.

Conclusion

I can see Centrica Business Systems and Highview Power having a long and profitable relationship.

Norway’s Sovereign Wealth Fund Acquires Stake In 573 MW Race Bank Offshore Wind Farm

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

This is the sub-heading.

A consortium made up of investment funds belonging to Australia-headquartered Macquarie Asset Management and Spring Infrastructure Capital has reached an agreement to divest a 37.5 per cent stake in the 573 MW Race Bank offshore wind farm in the UK to Norges Bank Investment Management.

These four paragraphs give more details of the deal.

The stake was sold to the Norwegian sovereign wealth fund for approximately GBP 330 million (about EUR 390.6 million).

According to Norges Bank Investment Management, the fund acquired Macquarie European Infrastructure Fund 5’s 25 per cent stake and Spring Infrastructure 1 Investment Limited Partnership’s 12.5 per cent interest in the Race Bank offshore wind farm.

A Macquarie Capital and Macquarie European Infrastructure Fund 5 consortium acquired a 50 per cent stake in Race Bank during the construction phase in 2016. Macquarie Capital divested its 25 per cent stake in the wind farm in 2017.

With the deal, Arjun Infrastructure Partners will remain co-investor for 12.5 per cent of the wind farm and Ørsted will remain a 50 per cent owner and operator of Race Bank.

These are my thoughts.

The Location of Race Bank Wind Farm

This map from the Outer Dowsing Web Site, shows Race Bank and all the other wind farms off the South Yorkshire, Lincolnshire and Norfolk coasts.

From North to South, wind farm sizes and owners are as follows.

  • Hornsea 1 – 1218 MW – Ørsted, Global Infrastructure Partners
  • Hornsea 2 – 1386 MW – Ørsted,Global Infrastructure Partners
  • Hornsea 3 – 2852 MW – Ørsted
  • Hornsea 4 – 2600 MW – Ørsted
  • Westernmost Rough – 210 MW – Ørsted and Partners
  • Humber Gateway – 219 MW – E.ON
  • Triton Knoll – 857 MW – RWE
  • Outer Dowsing – 1500 MW – Corio Generation, TotalEnergies
  • Race Bank – 573 MW – Ørsted,
  • Dudgeon – 402 MW – Equinor, Statkraft
  • Lincs – 270 MW – Centrica, Siemens, Ørsted
  • Lynn and Inner Dowsing – 194 MW – Centrica, TCW
  • Sheringham Shoal – 317 MW – Equinor, Statkraft
  • Norfolk Vanguard West – 1380 MW – RWE

Note.

  1. There is certainly a large amount of wind power on the map.
  2. Hornsea 1, 2 and 3 supply Humberside.
  3. Hornsea 4 will supply Norwich and North Norfolk.
  4. Norfolk Vanguard West would probably act with the other two wind farms in RWE’ Norfolk cluster.
  5. Ignoring Hornsea and Norfolk Vanguard West gives a total around 4.5 GW.
  6. There are also two 2 GW interconnectors to Scotland (Eastern Green Link 3 and Eastern Green Link 4) and the 1.4 GW Viking Link to Denmark.

I wouldn’t be surprised to see a large offshore electrolyser being built in the East Lincolnshire/West Norfolk area.

The primary purpose would be to mop up any spare wind electricity to avoid curtailing the wind turbines.

The hydrogen would have these uses.

  • Provide hydrogen for small, backup and peaker power stations.
  • Provide hydrogen for local industry, transport and agriculture,
  • Provide hydrogen for off-gas-grid heating.
  • Provide methanol for coastal shipping.

Any spare hydrogen would be exported by coastal tanker to Germany to feed H2ercules.

Do We Need Wind-Driven Hydrogen Electrolysers About Every Fifty Miles Or so Along The Coast?

I can certainly see a string along the East Coast between Humberside and Kent.

I can see others at possibly Freeport East and London Gateway.

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.

  1. There is also a visualisation and a map.
  2. Tesla batteries will be used.
  3. The The battery will have an output of 300 MW, with a capacity of 600 MWh. So it is another two-hour BESS.
  4. It should be operational in 2026.
  5. The battery is on a 35-acre site.
  6. 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.

  1. The East-West road is the A 47 Norwich by-pass.
  2. Norwich is to the North of the by-pass.
  3. 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.
  4. 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.

  1. The Swardeston substation is on a substantial site.
  2. The Norwich to Tilbury transmission line will have its Northern end at Swardeston substation.
  3. 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.

H2ercules

H2ercules is a project that will create the German hydrogen network.

The H2ercules web site, introduces the project with these two paragraphs.

A faster ramp-up of the hydrogen economy in Germany is more important than ever in order to drive forward the decarbonisation programme, put the German energy system on a more robust footing, and thus contribute towards a green security of supply. What this needs is a geographical realignment of the infrastructure for energy in gas form: Instead of flowing from the east of Germany to the west and south of the country, the gas – natural gas now, hydrogen in the future – will have to make its way in future from generation locations in the north-west to centres of consumption located mainly in the west and south. That also means that new sources will have to be connected, and gaps in existing pipeline networks will have to be closed. To speed up this vital process, OGE and RWE have developed the national infrastructure project “H2ercules”, which is intended to supply consumers in Germany’s south and west with domestically produced green hydrogen from the north of the country, in addition to imported sources. This will involve connecting up the electrolyser capacities that are currently being planned and developing more besides. RWE wants to create up to 1 GW of additional electrolyser capacity as part of the H2ercules project. For the connection component, OGE is planning to put 1,500 km of pipelines in place. For the most part, this will mean converting pipelines from the existing natural gas network to hydrogen, supplemented by newly constructed facilities. Converting natural gas pipelines is not only the more cost-efficient solution, but it also allows for a faster schedule. The system is expected to be supplemented by the planned hydrogen storages of RWE.

The current plan is to complete the project in three stages between 2026 and 2030, in order to connect industries to the hydrogen supply as soon as possible. The aim of this collaboration across multiple value levels is to resolve the chicken-and-egg problem on a super-sized scale and also smooth the way forward for other projects.

Note.

There will be a lot of conversion of the existing natural gas network to hydrogen.

RWE wants to create up to 1 GW of additional electrolyser capacity as part of the H2ercules project.

The second paragraph indicates to me, that they want to move fast.

This map from the H2ercules web site, indicate the proposed size of the network in 2030.

These three paragraphs describe how H2ercules will be developed.

OGE and RWE are both strong companies that aim to combine forces as part of the H2ercules project in order to overcome this Herculean task. While the task for OGE will be to convert the required gas pipelines to hydrogen and construct new pipelines, RWE will expand its electrolyser capacity and import green hydrogen in addition. Gas-fired power stations with a capacity of at least 2 GW will be converted to hydrogen, and new H2 -storages as well as H2-storages repurposed from gas storages on the Dutch border will be connected to the hydrogen supply system.

H2ercules also opens up new opportunities to connect Germany’s future centres of hydrogen consumption to key import routes, first via pipelines from Belgium and the Netherlands, and later via Norway and also from southern and eastern Europe, with the added prospects of import terminals for green molecules in Germany’s north. The project is thus contributing significantly to the creation of a European hydrogen market.

The first additional companies and organisations have already indicated their interest in this project, and it is expected that in the future smaller businesses will benefit in addition to large-scale customers, as the entire industry is guided towards a decarbonised future.

These are my thoughts.

Why Is It Called H2ercules?

I suspect, it’s nothing more, than the Germans wanted a recognisable and catchy name.

  • Name selection is not helped by the German for hydrogen, which is wasserstoff.
  • Hercules is Herkules in German, which doesn’t really help.
  • Projekt Wasserstoff isn’t as memorable as H2ercules, which at least isn’t English.

It looks to me, that the Germans have come up with a good acceptable compromise.

The Wilhemshaven Hydrogen Import Terminal

German energy company; Uniper is building a hydrogen import terminal at Wilhemshaven to feed H2ercules and 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.

Wilhelmshaven and Great Yarmouth are 272 miles or 438 kilometres apart, so a pipeline or a tanker link would be feasible to export hydrogen from Notfolk to Germany.

I suspect RWE  will 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.

RWE’s Norfolk Wind Farms

What is interesting me, is what Germany company; RWE is up to. Note 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, I wrote about the purchase in RWE And Vattenfall Complete Multi-Gigawatt Offshore Wind Transaction In UK.

This map from RWE shows the three wind farms, with respect to the Norfolk coast.

Could it be, that RWE intend to build a giant offshore electrolyser to the East of Great Yarmouth?

  • The planning permission for an electrolyser, which is eighty kilometres offshore, would be far easier, than for one onshore.
  • The hydrogen pipeline between Norfolk and Germany  would be less than 400 kilometres.
  • Hydrogen could also be brought ashore in Norfolk, if the price was right.
  • The Bacton gas terminal is only a few miles North of Great Yarmouth.

But the big advantage, is that the only onshore construction could be restricted to the Bacton gas terminal.

Adding More Wind Farms To The Electrolyser

Looking at the RWE map, the following should be noted.

South of Norfolk Vanguard East, there is the East Anglian Array wind farm, which by the end of 2026, will consist of these wind farms.

  • East Anglia One – 714 MW – 2020
  • East Anglia One North – 800 MW – 2026
  • East Anglia Two – 900 MW – 2026
  • East Anglia Three – 1372 MW – 2026

Note.

  1. The date is the commissioning date.
  2. There is a total capacity of 3786 MW
  3. All wind farms are owned by Iberdrola.
  4. There may be space to add other sections to the East Anglian Array.

I doubt, it would be difficult for some of Iberdrola’s megawatts to be used to generate hydrogen for Germany.

To the East of Norfolk Boreas and Norfolk Vanguard East, it’s Dutch waters, so I doubt the Norfolk cluster can expand to the East.

But looking at this map of wind farms, I suspect that around 4-5 GW of new wind farms could be squeezed in to the North-West of the the Norfolk Cluster and South of the Hornsea wind farms.

The 1.5 GW Outer Dowsing wind farm, which is being planned, will be in this area.

I can certainly see 8-10 GW of green electricity capacity being available to electrolysers to the North-East of Great Yarmouth.

Conclusion

UK offshore electricity could be the power behind H2ercules.

  • The hydrogen could be sent to Germany  by pipeline or tanker ship, as the distance is under 400 kilometers to the Wilhelmshaven hydrogen hub.
  • Extra electrolysers and wind farms could be added as needed.
  • The hydrogen won’t need to be shipped halfway round the world.

The cash flow won’t hurt the UK.

UK Energy Grid Needs £60bn Upgrade To Hit Green Target, Plan Says

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

This is the sub-heading.

The UK’s electricity network needs almost a further £60bn of upgrades to hit government decarbonisation targets by 2035, according to a new plan.

These five paragraphs explain the plan.

About 4,000 miles of undersea cables and 1,000 miles of onshore power lines are needed, said the National Grid’s Electricity Systems Operator (ESO).

The investment would add between £20 to £30 a year to customer bills, it said.

The government said the ESO’s plans were preliminary and yet to pass a “robust planning process”.

The plans were written up by the ESO, the organisation which runs the electricity network and would run the updated system it is calling for too. It is currently owned by National Grid but will transfer into government ownership later this year.

Its latest £58bn estimate is for work needed between 2030 and 2035 and comes on top of a previous £54bn estimate for work taking place between now and 2030.

These are my thoughts.

The Amount Of Undersea Cable

Edinburgh and London are roughly 400 miles apart as the train runs, so it looks like there could be the equivalent of ten underwater cables between the North of Scotland and England.

In Contracts Signed For Eastern Green Link 2 Cable And Converter Stations, I talked about the proposed 2 GW link between Peterhead in Scotland and Drax in England, which will be a double cable. So there’s the first two of these long cables.

It looks to me, that National Grid are proposing to use underwater cables wherever they can, so they avoid large expensive planning rows stirred up by Nimbies.

Monitoring The Undersea Cables

Last week Ofgem gave National Grid a £400,000 grant to develop new innovative technologies, which I wrote about in £400k For National Grid Innovation Projects As Part Of Ofgem Fund To Help Shape Britain’s Net Zero Transition.

One of the project is called HIRE – Hybrid-Network Improvement & Reliability Enhancement and will be used to check all these cables are performing as they should.

My electrical engineering experience tells me, that there must be some cunning way, that will detect that something is happening to the cable. The involvement of a technology company called Monitra in the project is a bit of a giveaway.

How Much Will It Cost Me?

Currently, UK consumers pay about £30 per year to have electricity delivered, so this will rise to between £50 and £60 per year.

That is just over a pound a week. I would pay about the same for a resident’s parking permit outside my house for an electric car and probably three times more for a petrol or diesel car.

Do We Have Enough Cable?

Two undersea cable factories are under development in Scotland and I suspect the 4,000 miles of undersea cables will be delivered on schedule and covered in saltires.

What About T-Pylons?

The latest onshore electricity transmission line between Hinckley Point C and Bristol, doesn’t use traditional pylons.

It uses T-pylons like these to connect the 3.26 GW nuclear power station.

Note that they are shorter, designed to be less intrusive, have a smaller footprint and are made from only ten parts.

I suspect they will cost less to install and maintain.

There is more on T-pylons in National Grid Energise World’s First T-Pylons.

I wouldn’t be surprised that some of the oldest traditional pylons will be replaced by T-pylons.

I am surprised that T-pylons are not mentioned in the BBC article.

I like T-pylons. How do you feel about them?

Eastern Green Link 2

This press release from National Grid, describes Eastern Green Link 2 like this.

Eastern Green Link 2 (EGL2) is a 525kV, 2GW high voltage direct current (HVDC) subsea transmission cable from Peterhead in Scotland to Drax in England delivered as a joint venture by National Grid and SSEN Transmission.

This map from National Grid, shows the route of the Eastern Green Link 2.

The Northern landfall is at Sandford Bay and the Southern landfall is at Wilsthorpe Beach.

This Google Map shows Sandford Bay and Peterhead power station.

Note.

  1. Sandford Bay occupies the North-East corner of the map.
  2. The red arrow indicates the main 400kV sub-station at Peterhead.
  3. The 2177 MW gas-fired Peterhead power station is to the East of the sub-station marked as SSE.

This second Google Map shows the onshore route of the cable from Wilsthorpe to Drax.

Note.

  1. Flamborough Head is in the North-East corner of the map.
  2. Wilsthorpe Beach is at Bridlington a couple of miles South of Flamborough Head.
  3. The red arrow indicates Drax Power station.
  4. An onshore underground cable will be installed from landfall in Wilsthorpe to a new onshore converter station built in Drax.

The EGL2 HVDC cable connection from Scotland to England consists of 436km of submarine cable and 69km of onshore cable.

Both converter stations will be on existing power station sites and the major onshore works will be the underground cable between Wilsthorpe and Drax.

Where Does Drax Go From Here?

Currently, Drax power station is a 2595 MW biomass-fired power station.

There are now other large power sources that could replace some or all of the output of Drax power station.

  • 2GW of Scottish wind power coming to Drax on Eastern Green Link 2.
  • 6 GW of offshore wind is being developed at the Hornsea wind farms.
  • 8 GW of offshore wind is being developed at the Dogger Bank wind farms.
  • 2.5 GW from the three gas-fired power stations at Keadby, two of which are likely to be fitted with carbon capture.
  • 1.8 GW from the proposed hydrogen-fired Keadby Hydrogen power station.

Given the bad feelings many have about Drax burning biomass, with 20.3 GW of electricity, you might think that shutting down Drax would be a simple solution.

But, according to Drax’s Wikipedia entry, it has a unique property.

Despite this intent for baseload operation, it was designed with a reasonable ability for load-following, being able to ramp up or down by 5% of full power per minute within the range of 50–100% of full power.

So Drax could be very useful in balancing the grid, by ramping up and down to fill the gap between production and need.

In addition, there is good biomass. This is from the Wikipedia entry.

A 100,000 tonne pa capacity straw pelletization facility was constructed at Capitol Park, Goole in 2008.

Drax are also promoting BECCS or Bioenergy carbon-capture and storage.

There is a Wikipedia entry for Bioenergy With Carbon Capture And Storage, of which this is the first couple of sentences.

Bioenergy with carbon capture and storage (BECCS) is the process of extracting bioenergy from biomass and capturing and storing the carbon, thereby removing it from the atmosphere. BECCS can theoretically be a “negative emissions technology” (NET).

I do feel that carbon capture and storage is a bit like sweeping the dust under the carpet, when you sweep the floor around it.

But carbon capture and use could be another matter.

This Google Map shows the Drax site.

Note how it is surrounded by agricultural land.

Could the power station be the source of pure carbon dioxide to be fed in greenhouses to flowers, herbs, salad vegetables, tomatoes and other plants?

I suspect there’s productive life left in Drax power station yet!

LionLink

LionLink, that is being developed by National Grid is a new type of interconnector, called a multi-purpose interconnector, that will connect Suffolk and The Netherlands via any convenient wind farms on the way. This means that the electricity generated can go where it is needed most.

I wrote about LionLink in World’s Largest-Of-Its-Kind Power Line To Deliver Clean Power To 1.8m UK Homes And Boost Energy Security.

Other Multi-Purpose Interconnectors

I can see other multi-purpose interconnectors like LionLink being built around the UK.

  • There could be one across the Dogger Bank to link out 8 GW of Dogger Bank wind farms with those of the Dutch, Danes and Germans on their section of the bank.
  • NorthConnect could be built between Scotland and Norway via some of the wind farms being developed to the North-East of Scotland.
  • Could wind farms to the North of Ireland use a multi-purpose interconnector between Scotland and Northern Ireland.
  • I can also see one or possibly two, being built across the Celtic Sea to link Devon, South Wales and Southern Ireland via the wind farms being developed in the area.
  • Will we also see a Channel multi-purpose interconnector to transfer electricity along the South Coast of England?

Some of these multi-purpose interconnectors could be key to creating a revenue stream, by exporting electricity, to countries in Europe, that have a pressing need for it.

Conclusion

National Grid’s excellent plan will lead to the end of the practice of shutting down wind turbines. The spare electricity will be exported to Europe, which will surely create a good cash-flow for the UK. This in turn will encourage developers to create more wind farms in the seas around the UK’s coasts.

Ørsted Greenlights 2.9 GW Hornsea 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.

Ørsted has taken the final investment decision (FID) on what the company says is the world’s single largest offshore wind farm, the 2.9 GW Hornsea 3, which is expected to be completed around the end of 2027.

These are the two introductory paragraphs.

In July 2022, Ørsted was awarded a contract for difference (CfD) for Hornsea 3 at an inflation-indexed strike price of GBP 37.35 per MWh in 2012 prices.

The CfD framework permits a reduction of the awarded CfD capacity. The company said it will use this flexibility to submit a share of Hornsea 3’s capacity into the UK’s upcoming allocation round 6.

With all the work, that Ørsted have done to protect kittiwakes, which I wrote about in Kittiwake Compensation, the company seems to have been taking the development of this wind farm carefully and this statement from the wonderfully-named Mads Nipper, Group President and CEO of Ørsted indicates that the UK Government has been persuasive in times, that are not totally favourable to wind farm developers.

Offshore wind is an extremely competitive global market, so we also welcome the attractive policy regime in the UK which has helped secure this investment. We look forward to constructing this landmark project, which will deliver massive amounts of green energy to UK households and businesses and will be a significant addition to the world’s largest offshore wind cluster.

But the article also has this paragraph.

According to Ørsted, most of Hornsea 3’s capital expenditure was contracted before recent inflationary pressures, securing competitive prices from the supply chain, adding that the larger wind turbines and the synergies with Hornsea 1 and 2 lead to lower operating costs.

It looks like Ørsted, may have taken advantage of Siemens well-publicised financial woes and got a good price for the over two hundred turbines.

This page on the Hitachi web site, describes their part in Hornsea 3, where this is said.

Hitachi Energy has supported Ørsted with the grid connection of Hornsea One and Hornsea Two, but Hornsea 3 will be the first phase to use HVDC application in the Hornsea cluster.

The overall HVDC system, including the offshore platform, is delivered in partnership with Aibel. Hitachi Energy will supply two HVDC Light® converter systems, while Aibel will deliver two HVDC offshore converter platforms. The platform is based on Hitachi Energy’s modular HVDC system including its advanced control and protection system, MACH™. As the HVDC offshore market grows and becomes more complex, Hitachi Energy will continue to develop solutions with its customers and partners to enable a more flexible offshore grid of the future.

Hitachi Energy is supplying four HVDC converter stations, which convert AC power to DC for transmission in the subsea cables, then reconvert it to AC for integration into the onshore grid. Two of the converter stations will be installed on offshore platforms and two at mainland grid connections.

Note.

  1. Hitachi are pushing their electrical innovation hard.
  2. Hitachi and Ørsted  have worked together on Hornsea 1 and 2.
  3. What better place is there for Hitachi to test their new modular HVDC system, than on one of the world’s largest wind farms?
  4. Hitachi appear to say, they like to develop with customers and partners.

It looks to me, that Ørsted may well have got new improved technology at an advantageous price.

This is the last paragraph of the article.

The Hornsea zone will also include the Hornsea 4 project, which could have a capacity of up to 2.6 GW. The wind farm received its development consent order from the UK government earlier in 2023 and is now eligible for forthcoming CfD allocation rounds.

So will Hornsea 4 be a slightly smaller version of Hornsea 3 using the same suppliers?

  • There could be savings in the design and manufacturing of the electrical systems, foundations, sub-stations and turbines.
  • Could for instance, Hitachi’s modular HVDC result in savings in converters and sub-stations, if the two wind farms shared infrastructure?
  • I’m sure that Siemens, Hitachi and the other suppliers will be happy to just keep rolling.
  • It would be an ideal follow-on.

It looks to me, that by using good design and management, and established suppliers, Ørsted  have managed to get the costs of Hornsea 3 and Hornsea 4 to a level, where the venture is profitable.
