The Anonymous Widower

Wind Farms On The East Coast Of Scotland

This map shows the proposed wind farms off the East coast of Scotland.

There are five wind farms in the map.

  • The green area is the cable corridor for Seagreen 1a
  • Inch Cape is the odd-shaped wind farm to the North and West of the green area
  • Seagreen at the top of the map, to the North of Inch Cape.
  • Marr Bank with the pink NE-SW hatching
  • Berwick Bank with the green NW-SE hatching
  • Neart Na Gaoithe is edged in blue to the South of the green area.

Berwick Bank and Marr Bank are both owned by SSE and appear to have been combined.

These are some more details on each of the now four wind farms.

Seagreen

These are details of the Seagreen wind farm.

  • Seagreen will be Scotland’s largest and the world’s deepest offshore wind farm when complete.
  • The first phase will have 114 turbines and a capacity of 1075 MW.
  • It will connect to the grid at a new substation at Tealing near Dundee.
  • The cables will run to the North of the Inch Cape wind farm.
  • It will be completed in 2023.
  • The second phase (1a), will have 36 turbines.
  • It may have larger turbines.
  • The cables will run in the green area to Cockenzie in East Lothian.

This press release from SSE is entitled Another Milestone For Scotland’s Largest Offshore Wind Farm As 4,800 Tonnes Offshore Platform Completed.

This is the first paragraph.

The topside forms the backbone of the offshore wind farm. At 40 metres long, 45 metres wide and 15 metres high, the heavyweight superstructure’s role is to collect and manage 1,075MW of power generated by the 114 Vestas wind turbines before transferring it ashore via around 60km of offshore subsea cabling.

This platform is used to connect the 114 turbines to the shore.

Inch Cape

This paragraph from the home page of the Inch Cape web site, describes the wind farm.

The Inch Cape Offshore Wind Farm, currently in late stage development, will see up to 72 turbines located 15 km off the Angus Coast and connect to the National Grid at Cockenzie, East Lothian. Once complete, it will be one of Scotland’s largest single sources of renewable energy and power up to 1 million homes with clean electricity.

The home page says it will generate up to 1 GW of electricity.

Neart Na Gaoithe

This sentence for the Wikipedia entry for the Neart Na Gaoithe web site describes the wind farm.

It is being developed by Mainstream Renewable Power at a cost of £1.4bn. Offshore work began in 2020, with completion planned for 2023.

The Wikipedia entry says it will generate up to 450 MW of electricity.

Berwick Bank

These two paragraphs from the project page of the Berwick Bank web site describes the wind farm.

Located in the North Sea, in the outer Firth of Forth, Berwick Bank Offshore Wind Farm has the potential to deliver up to 4.1 GW of installed capacity, making it one of the largest offshore opportunities in the world.

Berwick Bank Wind Farm is in the development stage and previously the project was comprised of two separate proposals, Berwick Bank Wind Farm and Marr Bank Wind Farm. Following initial rounds of consultation, it has been decided to combine our proposals into one single opportunity – Berwick Bank Wind Farm.

At 4.1 GW,  Berwick Bank is a big wind farm.

The capacity of the four farms can be summarised as follows.

  • Seagreen – 1075 MW
  • Neart Na Gaoithe – 450 MW
  • Inch Cape – 1000 MW
  • Berwick Bank – 4100 MW

This gives a total of 6625 MW.

Onshore And Offshore Wind Energy Capacity Predicted To Increase By 230% By 2030

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

The report was commissioned by Scottish Renewables to assess the effects on the supply chain in Scotland.

But it does show that Scotland is on the way to be able to supply a lot of its electricity from wind farms, which would be backed up by some of another of pumped storage schemes under development.

Norfolk Wind Farms Offer ‘Significant Benefit’ For Local Economy

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

This is a comprehensive article, which looks at the benefits of the huge Norfolk Boreas and Norfolk Vanguard wind farms will have to the economy of Norfolk.

The last section is devoted to Norfolk Nimby; Raymond Pearce.

This is the section.

Following the re-approval of the decision by the government, Mr Pearce says he is considering a new appeal over what he calls “a very poor decision”.

He is also sceptical of claims the two new wind farms will bring the economic gains promised by Vattenfall.

“It’s renewable energy at any cost and the cost here is to the environment in Norfolk,” he says.

“I don’t blame them for being positive about it, it’s their industry but they’re not looking at it holistically.”

He says he is not against renewable energy but thinks a better plan is needed to connect the offshore windfarms and minimise the number of cables and substations onshore.

It’s his money if he appeals, but we do need more wind, solar and other zero-carbon energy to combat global warming and its effects like the encroachment of the sea around Norfolk.

I believe, that building wind farms off the coast of Essex, Suffolk and Norfolk is a good move, as in the future, if we have spare electricity, it will be easy to export energy to Europe, through existing interconnectors.

But I do agree with him, that a better plan is needed to connect the offshore windfarms and minimise the number of cables and substations onshore.

A Norfolk Powerhouse

This map from Vattenfall, the developer of the two wind farms, shows the position of the farms and the route of the cable to the shore.

Note.

  1. The purple line appears to be the UK’s ten mile limit.
  2. Norfolk Boreas is outlined in blue.
  3. Norfolk Vanguard is outlined in orange.
  4. Cables will be run in the grey areas.
  5. Both wind farms are planned to have a capacity of 1.8 GW

Landfall will be just a few miles to the South of the Bacton gas terminal.

Bacton Gas Terminal

Bacton gas terminal is much more than a simple gas terminal.

With the need to decarbonise, I can’t help feeling that the Bacton gas terminal is very much on the decline and the site will need to be repurposed in the next few years.

Blending Hydrogen With Natural Gas

If you blend a proportion of hydrogen into natural gas, this has two beneficial effects.

  • Gas used in domestic and industrial situations will emit less carbon dioxide.
  • In the near future we will be replacing imported natural gas with hydrogen.

The hydrogen could be produced by a giant electrolyser at Bacton powered by the electricity from the two Norfolk wind farms.

At the present time, a research project call HyDeploy is underway, which is investigating the blending of hydrogen into the natural gas supply.

  • Partners include Cadent, Northern Gas Networks, the Health and Safety Executive, Keele University and ITM Power and Progessive Energy.
  • A first trial at Keele University has been hailed as a success.
  • It showed up to twenty percent of hydrogen by volume can be added to the gas network without the need to change any appliances or boilers.

Larger trials are now underway.

A Giant Electrolyser At Bacton

If hydrogen were to be produced at Bacton by a giant electrolyser, it could be used or distributed in one of the following ways.

  • Blended with natural gas for gas customers in Southern England.
  • Stored in a depleted gas field off the coast at Bacton. Both Baird and Deborah gas fields have been or are being converted to gas storage facilities, connected to Bacton.
  • Distributed by truck to hydrogen filling stations and bus and truck garages.
  • Greater Anglia might like a hydrogen feed to convert their Class 755 trains to hydrogen power.
  • Sent by a short pipeline to the Port of Great Yarmouth and possibly the Port of Lowestoft.
  • Exported to Europe, through one of the interconnectors.

Note.

  1. If the electrolyser were to be able to handle the 3.6 GW of the two wind farms, it would be the largest in the world.
  2. The size of the electrolyser could be increased over a few years to match the output of the wind farms as more turbines are installed offshore.
  3. There is no reason, why the electrical connection between Bacton and the landfall of the wind farm cable couldn’t be offshore.

If ITM Power were to supply the electrolyser, it would be built in the largest electrolyser factory in the World, which is in Sheffield in Yorkshire.

A Rail Connection To The Bacton Gas Terminal

This Google Map shows the area between North Walsham and the coast.

Note.

  1. North Walsham is in the South-Western corner of the map.
  2. North Walsham station on the Bittern Line is indicated by the red icon.
  3. The Bacton gas terminal is the trapezoidal-shaped area on the coast, at the top of the map.

I believe it would be possible to build a small rail terminal in the area with a short pipeline connection to Bacton, so that hydrogen could be distributed by train.

How Much Hydrogen Could Be Created By The Norfolk Wind Farms?

In The Mathematics Of Blending Twenty Percent Of Hydrogen Into The UK Gas Grid, I said the following.

Ryze Hydrogen are building the Herne Bay electrolyser.

  • It will consume 23 MW of solar and wind power.
  • It will produce ten tonnes of hydrogen per day.

The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.

Each of the Norfolk wind farms, if they were working flat out would produce 43.2 GWh  of electricity in a day.

Dividing the two figures gives a daily production rate of 782.6 tonnes of hydrogen per day.

But what happens if the wind doesn’t blow?

This is where the gas storage in the Baird, Deborah and other depleted gas fields comes in.In times of maximum wind, hydrogen is stored for use when the wind doesn’t blow.

Conclusion

I believe a plan like this, would be much better for Norfolk, the UK and the whole planet.

Using the existing gas network to carry the energy away from Norfolk, could mean that the electricity connection across Norfolk could be scaled back.

New Electricity ‘Superhighways’ Needed To Cope With Surge In Wind Power

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

This is the first two paragraphs.

Energy companies are pushing for the rapid approval of new electricity “superhighways” between Scotland and England amid fears that a lack of capacity will set back the country’s wind power revolution.

Businesses including SSE and Scottish Power are calling on the industry regulator Ofgem to approve a series of major new north-south power cables in a bid to ease congestion on the existing electricity network.

These points are mentioned in the article.

  • Current capacity is 6 GW, which even now is not enough.
  • Another 17 GW of capacity will be needed by 2033.
  • Wind farms in Scotland have been switched off and replaced by gas-fired power stations because of a lack of grid capacity.
  • Another 25 GW of wind farms could be built after leases were awarded last month.

Two North-South interconnectors are being planned.

Peterhead And Drax

This is being proposed by SSE and National Grid.

  • It will be an undersea cable.
  • It will be two cables, each with a capacity of 2 GW.
  • Peterhead and Drax power station are four hundred miles apart by road and 279 miles as the seagull flies, as a lot of the route would be over the sea. So an undersea connection would appear to be sensible.
  • Peterhead is on the coast, so connecting an undersea interconnector shouldn’t be too challenging or disruptive to the locals.
  • Drax power station is a 4 GW power station and the largest in the UK, so it must have good grid connections.

This Google Map shows the location of Drax power station in relation to Hull, Scunthorpe and the rivers in the area.

Note.

  1. Drax is marked by the red arrow in the West of the map.
  2. The large body of water in the East is the Humber Estuary.
  3. Hull is on the North Bank of the Humber.
  4. Scunthorpe, which is famous for its steel industry is South of the Humber in the middle of the map.
  5. To the West of Scunthorpe the Humber splits into the Trent and the Ouse.
  6. The Ouse leads all the way to Drax power station.

I suspect an undersea cable could go up the Humber and Ouse to Drax power station.

Is it a coincidence that both Drax power station and the proposed link to Peterhead are both around 4 GW?

Consider.

  • Drax is a biomass power station, so it is not a zero carbon power station.
  • Drax produces around six percent of the UK’s electricity.
  • Most of the biomass comes by ship from North America.
  • Protest groups regularly have protests at Drax because of its carbon emissions.
  • Drax Group are experimenting with carbon capture.
  • Drax is a big site and a large energy storage system could be built there.
  • Wind is often criticised by opponents, saying wind is useless when the wind doesn’t blow.
  • The Scots would be unlikely to send power to England, if they were short.

This is also said about Drax in Wikipedia.

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.

I take this it means it can be used to top up electricity generation to meet demand. Add in energy storage and it could be a superb load-follower.

So could the similar size of the interconnector and Drax power station be deliberate to guarantee England a 4 GW feed at all states of the wind?

I don’t think it is a coincidence.

Torness And Hawthorn Pit And Torness and South Humberside

These two cables are being proposed by Scottish Power.

  • Each will be two GW.
  • Torness is the site of the 1.36 GW Torness nuclear power station, which is likely to be decommissioned before 2030.
  • Torness will have good grid connections and it is close to the sea.
  • Hawthorn Pit is a large closed coal mine to the North of Newcastle, with a large substation close to the site. I suspect it will be an ideal place to feed power into the grid for Newcastle and it is close to the sea.
  • Just South of Hawthorn Pit are the 1.32 GW Hartlepool nuclear power station, which will be decommissioned in 2024 and the landfall of the cables to the massive Dogger Bank wind farm.
  • As I showed earlier with Drax, the Humber would be an ideal estuary to bring underwater power cables into the surrounding area. So perhaps the cable will go to Scunthorpe for the steelworks.
  • As at Drax, there is backup in South Humberside, but here it is from the two Keadby gas-fired power stations.

The article in the Telegraph only gives the briefest of details of Scottish Power’s plans, but I suspect, that given the locations of the ends of the interconnectors, I suspect the cables will be underwater.

Conclusion

It strikes me that all three interconnectors have been well thought thought and they serve a variety of objectives.

  • Bring Scottish wind power, South to England.
  • Connect wind farms to the two nuclear power station sites at Hartlepool and Torness, that will close at the end of the decade.
  • Allow the big 4 GW biomass-fired station at Drax to back up wind farms and step in when needed.
  • Cut carbon emissions at Drax.
  • Use underwater cables as much as possible to transfer the power, to avoid the disruption of digging in underground cables.

It looks to be a good plan.

Norfolk Vanguard Offshore Wind Farm Re-approved By Government

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

These are the two introductory paragraphs.

An offshore wind farm capable of generating electricity for nearly two million homes has been re-approved by government after consent was previously overturned by a High Court judge.

Vattenfall’s 1.8-gigawatt Norfolk Vanguard project had been granted consent by the Department for Business, Energy and Industrial Strategy (BEIS).

Note.

  1. Norfolk Boreas and Norfolk Vanguard are a pair of 1.8 GW offshore wind farms to be developed 72 and 47 kilometres off the Norfolk coast by Swedish company; Vattenfall.
  2. Hinckley Point C will have a capacity of 3.25 GW.

This map shows the two fields in relation to the coast.

Note.

  1. The purple line appears to be the UK’s ten mile limit.
  2. Norfolk Boreas is outlined in blue.
  3. Norfolk Vsnguard is outlined in orange.
  4. Cables will be run in the grey areas.

This second map shows the onshore cable.

Note.

  1. The cables are planned to come ashore between Happisburgh and Eccles-on-Sea.
  2. Bacton is only a short distance up the coast.
  3. The onshore cable is planned to go from here across Norfolk to the Necton substation.

But the planning permission was overturned by a legal ruling.

This article on the BBC is entitled Norfolk Vanguard: Ministers Wrong Over Wind Farm Go-Ahead, Says Judge.

These are the first four paragraphs.

A High Court judge has quashed permission for one of the world’s largest offshore wind farms to be built off the east coast of England.

The Norfolk Vanguard Offshore Wind Farm was granted development consent in July by the Secretary of State for Business, Energy and Industrial Strategy (BEIS).

But Mr Justice Holgate overturned the decision following legal action from a man living near a planned cable route.

A Department for BEIS spokeswoman said it was “disappointed by the outcome”.

This is a paragraph in today’s BBC article.

Kwasi Kwarteng, Secretary of State at the Department of Business, Energy and Industrial Strategy, granted development consent for the wind farm, having re-determined the application.

So will we be back to the Law Courts?

In Is There A Need For A Norfolk-Suffolk Interconnector?, I said this.

But seriously, is it a good idea to dig an underground cable all the way across Norfolk or in these times build a massive overhead cable either?

Perhaps the solution is to connect the Norfolk Boreas And Norfolk Vanguard wind farms to a giant electrolyser at Bacton, which creates hydrogen.

  • The underground electricity cable across Norfolk would not be needed.
  • Bacton gas terminal is only a few miles up the coast from the cable’s landfall.
  • The UK gets another supply of gas.
  • The hydrogen is blended with natural gas for consumption in the UK or Europe.
  • A pure hydrogen feed can be used to supply hydrogen buses, trucks and other vehicles, either by tanker or pipeline.
  • Excess hydrogen could be stored in depleted gas fields.

Thye main benefit though, would be that it would transform Bacton gas terminal from a declining asset into Norfolk’s Hydrogen Powerhouse.

For more information on blending hydrogen into our natural gas supply see HyDeploy.

Dogger Bank C In UK Offshore Wind First To Provide Reactive Power Capability

The title of this post, is the same as that of this press release from the Dogger Bank wind farm.

This paragraph gives an explanation.

Dogger Bank Wind Farm has secured a UK power first by becoming the first offshore wind farm project to win a tender from National Grid ESO to provide reactive power capability. The sector-first contract will help deliver a greener grid, maintain a stable voltage power supply, and help drive down UK consumer costs by millions of pounds.

Note that the three Dogger Bank wind farms; A, B and C will each have a capacity of 1.2 GW and that Hartlepool nuclear power station has a capacity of 1.32 GW. The latter is due to be decommissioned in 2024.

So the wind farms will effectively replace the nuclear power station.

This paragraph describes the contract.

Under new £22.5m Pennines Voltage Pathfinder contracts announced today, National Grid ESO has awarded a 10-year power contract to Dogger Bank C that will see its onshore converter station at Lazenby in the North-East of England provide 200 MVAr* of reactive power capability between 2024 and 2034. This marks the first time that an offshore wind transmission asset has been awarded a contract through a reactive power tender by National Grid ESO.

I suspect that there will need to be some form of energy storage added to the system somewhere, either at Lazenby or could we see a system like one of Highview Power’s CRYOBattery installed offshore?

It should be noted that CRYOBatteries are no more complicated, than some of the equipment installed on offshore gas and oil platforms.

The Lackenby Substation

It does seem that there has been a mix-up between the two nearby villages of Lazenby and Lackenby.

I can’t find a Lazenby substation, but I can find one at Lackenby.

This Google Map shows that the location of the Lackenby substation.

This second map shows the substation in more detail.

Note.

  1. There are a lot of large chemical works on both banks of the Tees.
  2. I can find nothing on the route of the cable from Dogger Bank C to Lackenby substation.
  3. Perhaps, it’s planned to go up the River Tees or it could come ashore South of the mouth of the River Tees.

Plans must be published soon, so that the substation can be updated before the wind farm is commissioned.

Amp Wins Consent For 800MW Scots Battery Complex

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

These are the first two paragraphs.

Canadian storage player Amp Energy has revealed that its 800MW battery portfolio in Scotland has secured planning consent.

The portfolio is due to be operational in April 2024 and will comprise two 400MW battery facilities, each providing 800 megawatt-hours of energy storage capacity.

Some other points from the article.

  • The two facilities will be located at Hunterston and Kincardine.
  • They will be the two  largest grid-connected battery storage facilities in Europe.
  • The two batteries will be optimised by Amp Energy‘s proprietary software.

This Google Map shows the Hunterston area.

Note.

  1. The Hunterston A and Hunterston B nuclear power stations, which are both being decommissioned.
  2. Hunterston B only shut down on the 7th of January, this year.
  3. There is also a large brownfield site in the North-East corner of the map.

This second Google Map shows the South-East corner of the nuclear power station site.

It’s certainly got a good grid connection.

But then it had to support.

  • The Hunterston A nuclear power station rated at 360 MW.
  • The Hunterston B nuclear power station rated at 1.2 GW.
  • The Western HVDC Link, which is an interconnector to Connah’s Quay in North Wales, that is rated at 2.2 GW.

I’m sure that National Grid has a suitable socket for a 400 MW battery.

This Google Map shows the Kincardine area.

Note.

  1. The Clackmannanshire Bridge down the Western side of the map.
  2. The Kincardine Substation to the East of the bridge close to the shore of the River Forth.
  3. The 760 MW Kincardine power station used to be by the substation, but was demolished by 2001.

As at Hunterston, I’m sure that National Grid could find a suitable socket for a 400 MW battery.

Amp Energy’s Philosophy

As a trained Control Engineer I like it.

  • Find a well-connected site, that can handle upwards of 400 MW in and out.
  • Put in a 800 MWh battery, that can handle 400 MW in and out.
  • Optimise the battery, so that it stores and supplies electricity as appropriate.
  • Throw in a bit of artificial intelligence.

Old power station sites would seem an ideal place to site a battery. Especially, as many demolished coal, gas and nuclear stations are around 400-600 MW.

It should be noted that Highview Power are building a 50 MW/400 MWh CRYOBattery on an old coal-fired power station site in Vermont.

The Western HVDC Link

I mentioned earlier that the Northern end of the Western HVDC Link, is at Hunterston.

The Wikipedia entry for the Western HVDC Link, says this about the link.

The Western HVDC Link is a high-voltage direct current (HVDC) undersea electrical link in the United Kingdom, between Hunterston in Western Scotland and Flintshire Bridge (Connah’s Quay) in North Wales, routed to the west of the Isle of Man.[2] It has a transmission capacity of 2,250 MW and became fully operational in 2019.

The link is 262 miles long.

This Google Map shows the Connah’s Quay area in North Wales.

Note.

  1. The red arrow indicates the Flintshire Bridge HVDC converter station, which is the Southern end of the Western HVDC Link.
  2. The Borderlands Line between Liverpool and Chester, runs North-South to the East of the convertor station.
  3. To the East of the railway are two solar farms. The Northern one is Shotwick Solar Park, which at 72 MW is the largest solar farm in the UK.
  4. To the West of the converter station, just to the East of the A 548 road, is the 498 MW Deeside power station.
  5. Follow the A548 road to the West and over the River Dee, the road passes South of the 1420 MW Connah’s Quay Power station.
  6. The two power stations burn gas from Liverpool Bay.
  7. There are a lot of wind turbines along the North Wales Coast and Liverpool Bay.

The map also shows a lot of high electricity users like Tata Steel.

I can certainly see why the Western HVDC Link was built to connect Scotland and North Wales.

  • There is a lot of renewable energy generation at both ends.
  • There are heavy electricity users at both ends.
  • The Scottish Central Belt is at the North.
  • Greater Merseyside is at the South.

The Western HVDC Link is an electricity by-pass, that must have avoided expensive and controversial construction on land.

I wouldn’t be surprised to see another 400 MW/800 MWh battery at the Southern end.

Conclusion

The Canadians seem to have bagged two of the best battery sites in Europe.

  • Both sites would appear to be able to handle 400 MW, based on past capabilities.
  • There is lots of space and extra and/or bigger batteries can probably be connected.
  • Scotland is developing several GW of wind power.

I can see Amp Energy building a series of these 400 MW sites in the UK and around Europe.

This is the big news of the day!

Why Use A Hydrogen Pipeline Rather Than A Electricity Cable To Bring Electricity Ashore From A Windfarm?

A comment to the post entitled Siemens Gamesa Partners On Offshore Wind-to-Hydrogen, was as follows.

Trying to get my head around this concept. Build an electrolysis plant in the North Sea and run a hydrogen pipeline to shore, rather than generating electricity and transferring the power by undersea cable to a shore based electrolysis plant. Can it really be better technically and economically? Someone convince me.

The reasons probably all come down to saving money and hassle.

Reusing Existing Infrastructure

Supposing, you have an offshore gas field, which is on the point of being worked out.

  • It has a well-maintained platform on top.
  • It has a pipe to an onshore terminal that handles the natural gas and distributes it to end-users.

Supposing the following are possible.

  • Building a large wind farm in the vicinity of the platform.
  • Using the gas field for hydrogen storage.
  • Converting the gas terminal from natural gas to hydrogen.
  • The end-users can convert to hydrogen.

In some cases the end-users might even prefer hydrogen to natural gas, to help their own decarbonisation.

I would suspect that there will be a sound economic case to use hydrogen, where wind farms are developed, in the same areas as worked-out gas fields.

  • Platform demolition costs are deferred.
  • No HVDC link is needed, with an expensive converter station at the shore end.
  • The new system comes with energy storage.

The only extra cost might be that an offshore electrolyser is more expensive than an onshore one.

Engineering Resources

The engineering resources needed for a gas pipeline are different to those needed for an electrical system.

But because gas pipelines are a declining industry, they will be readily available.

Less Planning Hassle

There have been some objections to the development of wind farm terminals by Nimbies.

If a terminal is converted from natural gas to hydrogen, I suspect there will be fewer objections.

Better Control Of Wind Farms

There have been stories of wind farms having to be switched off because there is no-one to buy the electricity.

If some form of offshore hydrogen storage is possible, then the electricity can be used to generate hydrogen, which can be piped ashore, when it is needed.

It Won’t Be One Type Fits All

I suspect we’ll see some hybrid systems and other innovative engineering.

Conclusion

I believe that in a drive to cut costs, we’ll see a lot of energy brought ashore as hydrogen gas.

Future Offshore Wind Power Capacity In The UK

I am building this table, so that I can get a feel for the electricity needs of the UK.

According to Wikipedia, on February 2020, there were thirty six offshore wind farms consisting of 2180 turbines with a combined capacity of 8113 megawatts or 8.113 gigawatts.

Currently, these offshore wind farms are under construction, proposed or are in an exploratory phase.

  • Triton Knoll – 857 MW – 2021 – Under Construction
  • Hornsea Two – 1386 MW – 2022 – Under Construction
  • Moray East – 960 MW – 2022 – Under Construction
  • Neart Na Gaoithe – 450 MW – 2023 – Under Construction
  • Seagreen Phase 1 – 1075 MW – 2023 – Under Construction
  • Dogger Bank A – 1200 MW – 2023/24 – Proposed
  • Dogger Bank B – 1200 MW – 2024/25 – Proposed
  • Dogger Bank C – 1200 MW – 2024/25 – Proposed
  • Moray West – 1200 MW – 2024/25  – Exploratory
  • Hornsea Three – 2400 MW – 2025 – Proposed
  • East Anglia One North 800 MW – 2026 – Exploratory
  • East Anglia Two – 900 MW – 2026 – Exploratory
  • East Anglia Three – 1400 MW – 2026 – Exploratory
  • Sofia Offshore Wind Farm Phase 1 – 1400 MW – 2023/2026 – Under Construction
  • Hornsea Four – 1000 MW (?) – 2027 – Exploratory
  • Rampion Two Extension – 1200 MW – Exploratory
  • Norfolk Vanguard – 1800 MW – Exploratory
  • Norfolk Boreas – 1800 MW – Exploratory

Note.

  1. The date is the possible final commissioning date.
  2. I have no commissioning dates for the last three wind farms.
  3. Wikipedia says that the Hornsea Four capacity is unknown by Ørsted due to the ever increasing size of available wind turbines for the project.

I can total up these wind farms by commissioning date.

  • 2021 – 857 MW
  • 2022 – 2346 MW
  • 2023 – 1525 MW
  • 2024 – 1200 MW
  • 2025 – 6000 MW
  • 2026 – 4500 MW
  • Others – 5800 MW

I can draw these conclusions.

  • Total wind farm capacity commissioned each year is increasing.
  • It looks like there will be a capacity to install up to 5000 or 6000 MW every year from about 2025.
  • If we add my figures for 2021-2026 to the 8113 MW currently installed we get 24541 MW.
  • Adding in 6000 MW for each of the four years from 2027-2030 gives a total of 48541 MW or 48.5 GW.

As I write this on a Sunday afternoon, wind power (onshore and offshore) is supplying 13 GW or forty-four percent of our electricity needs.

I have further thoughts.

Parallels With North Sea Oil And Gas

I was very much involved in the development of North Sea oil and gas, as my software was used on a large number of the projects. I had many discussions with those managing these projects and what was crucial in shortening project times was the increasing availability of bigger rigs, platforms and equipment.

Big certainly was better.

I believe that as we get more experienced, we’ll see bigger and better equipment speeding the building of offshore wind farms.

Reuse of Redundant North Sea Oil And Gas Platforms

Don’t underestimate the ability of engineers to repurpose redundant oil and gas platforms for use with windfarms.

Electrolysers on the platforms can convert the electricity into hydrogen and use redundant gas pipes to bring it ashore.

Some processes like steelmaking could use a lot of hydrogen.

Platforms can be used as sub-stations to collect electricity from windfarms and distribute it to the various countries around the North Sea.

Hydrogen

Some processes like steelmaking could use a lot of hydrogen. And I don’t think steelmakers would be happy, if the supply was intermittent.

So why not produce it with giant electrolysers on redundant oil and gas platforms and store it in redundant gas fields under the sea?

A large store of hydrogen under the sea could have the following uses.

  • Steelmaking.
  • Feedstock for chemical manufacture.
  • Transport
  • Power generation in a gas-fired power station, that can run on hydrogen.

It would just need a large enough hydrogen store.

Energy Storage

This large amount of wind power will need a large amount of energy storage to cover for when the wind doesn’t blow.

Some of this storage may even be provided by using hydrogen, as I indicated previously.

But ideas for energy storage are coming thick and fast.

The North Sea Link To Norway

The North Sea Link is much more important than an interconnector between Blyth in Northumberland and Norway.

  • At the Norwegian end the link is connected to a vast pumped storage energy system in the mountains of Norway.
  • This pumped storage system is filled in two ways; Norwegian rain and snow and UK wind power through the interconnector.
  • In times of need, we can draw electricity through the interconnector from Norway.
  • It has a capacity of 1.4 GW.
  • It was delivered on time for a cost of around €2 billion.

It can almost be thought of as an international bank of electricity and is probably one of the most significant pieces of European infrastructure built in recent years.

There are also plans to build NorthConnect, that would connect Peterhead in Scotland to Norway.

Conclusion

It looks like we’ll be able to reap the wind. And possibly 50 GW of it!

Singapore-Based Enterprize To Build $10bn Wind Farm Off Irish Coast

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

This is the first paragraph.

A Singapore-based offshore wind developer has signed an agreement to build a huge $10 billion (€8.88 billion) wind farm off the coast of Ireland to power a green hydrogen facility.

This is certainly a large investment.

  • The windfarm will have a capacity of 4 GW.
  • Hydrogen will be produced for the Irish market and some will be converted to ammonia for export.
  • The hydrogen will be produced at the Green Marlin hydrogen facility at Bantry Bay.
  • I’ve not heard of Enterprize before, but the company  is also developing a 3.4 gigawatt offshore wind farm in Vietnam and is looking at Brazil.

Enterprize Energy are obviously very ambitious.

This article on Fuel Cell Works, which is entitled Zenith Energy And EI-H2 Announce Joint Venture For Green Facility At Bantry Bay, gives more details of the Green Marlin project.

Conclusion

There are some big companies investing billions of pounds, dollars and euros in hydrogen.
