Could Norfolk And Suffolk Be Powered By Offshore Wind?
This week this article on the BBC was published, which had a title of Government Pledges £100m For Sizewell Nuclear Site.
These are the first three paragraphs.
The government is putting up £100m to support the planned Sizewell C nuclear plant in Suffolk, Business and Energy Secretary Kwasi Kwarteng has announced.
The investment marks the latest stage in efforts to build the £20bn reactor on the east coast of England.
However, it does not commit the government to approving the project, which is still subject to negotiations.
My view of the proposed Sizewell C nuclear plant is that of an engineer, who used to live within thirty minutes of the Sizewell site.
- Hinckley Point C power station, which is currently being constructed, will have a nameplate capacity of 3.26 GW.
- Sizewell C would probably be to a similar design and capacity to Hinckley Point C.
- Sizewell C would likely be completed between 2033-2036.
- Sizewell B is a 1250 MW station, which has a current closing date of 2035, that could be extended to 2055.
- East Anglia and particularly the mega Freeport East, that will develop to the South at the Ports of Felixstowe and Harwich will need more electricity.
- One of the needs of Freeport East will be a large supply of electricity to create hydrogen for the trains, trucks, ships and cargo handling equipment.
- Sizewell is a large site, with an excellent connection to the National Grid, that marches as a giant pair of overhead cables across the Suffolk countryside to Ipswich.
But.
- We still haven’t developed a comprehensive strategy for the management of nuclear waste in the UK. Like paying for the care of the elderly and road pricing, it is one of those problems, that successive governments have kept kicking down the road, as it is a big vote loser.
- I was involved writing project management software for forty years and the building of large nuclear power plants is littered with time and cost overruns.
- There wasn’t a labour problem with the building of Sizewell B, as engineers and workers were readily available. But with the development of Freeport East, I would be very surprised if Suffolk could provide enough labour for two mega-projects after Brexit.
- Nuclear power plants use a lot of steel and concrete. The production of these currently create a lot of carbon dioxide.
- There is also a large number of those objecting to the building of Sizewell C. It saddened me twenty-five years ago, that most of the most strident objectors, that I met, were second home owners, with no other connection to Suffolk.
The older I get, the more my experience says, that large nuclear power plants aren’t always a good idea.
Small Modular Nuclear Reactors
In Is Sizewell The Ideal Site For A Fleet Of Small Modular Nuclear Reactors?, I looked at building a fleet of small modular nuclear reactors at Sizewell, instead of Sizewell C.
I believe eight units would be needed in the fleet to produce the proposed 3.26 GW and advantages would include.
- Less land use.
- Less cost.
- Less need for scarce labour.
- Easier to finance.
- Manufacturing modules in a factory should improve quality.
- Electricity from the time of completion of unit 1.
But it would still be nuclear.
Wind In The Pipeline
Currently, these offshore wind farms around the East Anglian Coast are under construction, proposed or are in an exploratory phase.
- East Anglia One – 714 MW – 2021 – Finishing Construction
- East Anglia One North 800 MW – 2026 – Exploratory
- East Anglia Two – 900 MW – 2026 – Exploratory
- East Anglia Three – 1400 MW – 2026 – Exploratory
- Norfolk Vanguard – 1800 MW – Exploratory
- Norfolk Boreas – 1800 MW – Exploratory
- Sheringham Shoal/Dudgeon Extension – 719 MW – Exploratory
Note.
- The date is the possible final commissioning date.
- I have no commissioning dates for the last three wind farms.
- The East Anglia wind farms are all part of the East Anglia Array.
These total up to 8.13 GW, which is in excess of the combined capacity of Sizewell B and the proposed Sizewell C, which is only 4.51 GW.
As it is likely, that by 2033, which is the earliest date, that Sizewell C will be completed, that the East Anglia Array will be substantially completed, I suspect that East Anglia will not run out of electricity.
But I do feel that to be sure, EdF should try hard to get the twenty year extension to Sizewell B.
The East Anglia Hub
ScottishPower Renewables are developing the East Anglia Array and this page on their web site, describes the East Anglia Hub.
This is the opening paragraph.
ScottishPower Renewables is proposing to construct its future offshore windfarms, East Anglia THREE, East Anglia TWO and East Anglia ONE North, as a new ‘East Anglia Hub’.
Note.
- These three wind farms will have a total capacity of 3.1 GW.
- East Anglia ONE is already in operation.
- Power is brought ashore at Bawdsey between Felixstowe and Sizewell.
I would assume that East Anglia Hub and East Anglia ONE will use the same connection.
Norfolk Boreas and Norfolk Vanguard
These two wind farms will be to the East of Great Yarmouth.
This map from Vattenfall web site, shows the position of the two wind farms.
Note.
- Norfolk Boreas is outlined in blue.
- Norfolk Vanguard is outlined in orange.
- I assume the grey areas are where the cables will be laid.
- I estimate that the two farms are about fifty miles offshore.
This second map shows the landfall between Eccles-on-Sea and Happisburgh.
Note the underground cable goes half-way across Norfolk to Necton.
Electricity And Norfolk And Suffolk
This Google Map shows Norfolk and Suffolk.
Note.
- The red arrow in the North-West corner marks the Bicker Fen substation that connects to the Viking Link to Denmark.
- The East Anglia Array connects to the grid at Bawdsey in the South-East corner of the map.
- Sizewell is South of Aldeburgh in the South-East corner of the map.
- The only ports are Lowestoft and Yarmouth in the East and Kings Lynn in the North-West.
There are few large towns or cities and little heavy industry.
- Electricity usage could be lower than the UK average.
- There are three small onshore wind farms in Norfolk and none in Suffolk.
- There is virtually no high ground suitable for pumped storage.
- There are lots of areas, where there are very few buildings to the square mile.
As I write this at around midday on a Saturday at the end of January, 49 % of electricity in Eastern England comes from wind, 20 % from nuclear and 8 % from solar. That last figure surprised me.
I believe that the wind developments I listed earlier could provide Norfolk and Suffolk with all the electricity they need.
The Use Of Batteries
Earlier, I talked of a maximum of over 7 GW of offshore wind around the cost of Norfolk and Suffolk, but there is still clear water in the sea to be filled between the existing and planned wind farms.
Batteries will become inevitable to smooth the gaps between the electricity produced and the electricity used.
Here are a few numbers.
- East Anglian Offshore Wind Capacity – 8 GW
- Off-Peak Hours – Midnight to 0700.
- Typical Capacity Factor Of A Windfarm – 20 % but improving.
- Overnight Electricity Produced at 20 % Capacity Factor – 11.2 GWh
- Sizewell B Output – 1.25 GW
- Proposed Sizewell C Output – 3.26 GW
- Largest Electrolyser – 24 MW
- World’s Largest Lithium-Ion Battery at Moss Landing – 3 GWh
- Storage at Electric Mountain – 9.1 GWh
- Storage at Cruachan Power Station – 7.1 GWh
Just putting these large numbers in a table tells me that some serious mathematical modelling will need to be performed to size the batteries that will probably be needed in East Anglia.
In the 1970s, I was involved in three calculations of a similar nature.
- In one, I sized the vessels for a proposed polypropylene plant for ICI.
- In another for ICI, I sized an effluent treatment system for a chemical plant, using an analogue computer.
- I also helped program an analysis of water resources in the South of England. So if you have a water shortage in your area caused by a wrong-sized reservoir, it could be my fault.
My rough estimate is that the East Anglian battery would need to be at least a few GWh and capable of supplying up to the output of Sizewell B.
It also doesn’t have to be a single battery. One solution would probably be to calculate what size battery is needed in the various towns and cities of East Anglia, to give everyone a stable and reliable power supply.
I could see a large battery built at Sizewell and smaller batteries all over Norfolk and Suffolk.
But why stop there? We probably need appropriately-sized batteries all over the UK, with very sophisticated control systems using artificial intelligent working out, where the electricity is best stored.
Note that in this post, by batteries, I’m using that in the loosest possible way. So the smaller ones could be lithium-ion and largest ones could be based on some of the more promising technologies that are under development.
- Highview Power have an order for a 50 MW/500 MWh battery for Chile, that I wrote about in The Power Of Solar With A Large Battery.
- East Anglia is an area, where digging deep holes is easy and some of Gravitricity’s ideas might suit.
- I also think that eventually someone will come up with a method of storing energy using sea cliffs.
All these developments don’t require large amounts of land.
East Anglia Needs More Heavy Consumers Of Electricity
I am certainly coming to this conclusion.
Probably, the biggest use of electricity in East Anglia is the Port of Felixstowe, which will be expanding as it becomes Freeport East in partnership with the Port of Harwich.
One other obvious use could be in large data centres.
But East Anglia has never been known for industries that use a lot of electricity, like aluminium smelting.
Conversion To Hydrogen
Although the largest current electrolyser is only 24 MW, the UK’s major electrolyser builder; ITM Power, is talking of a manufacturing capacity of 5 GW per year, so don’t rule out conversion of excess electricity into hydrogen.
Conclusion
Who needs Sizewell C?
Perhaps as a replacement for Sizewell B, but it would appear there is no pressing urgency.
Felixstowe And Harwich Ports Submit Bid For ‘Freeport’ Status
The title of this post is the same as this article on the BBC.
These are the first three paragraphs.
A bid for “freeport” status for two existing ports has been submitted after the project was approved by a council.
East Suffolk Council unanimously backed the bid for the Port of Felixstowe and Harwich International to become one of 10 freeport facilities across the UK.
Freeport East would see owners Hutchison operate a single custom zone covering both coastal ports.
I think, some will think this a bit cheeky, but I think it is a product of the characters of the counties of Essex and Suffolk.
I was conceived in Suffolk and have probably spent half my life in the county.
It’s a county that thinks big.
- Is there another woman, who as Boudica did, assembled an army of hundreds of thousands and attempted to throw an unwelcome invader out of her country?
- The history of her tribe; the Iceni is closely tied, according to some historians, to the development of the thoroughbred racehorse at New Horse Market or Newmarket as it is known today!
- Newmarket is to horse racing as St. Andrews is to golf.
- The town is home of about 3,500 horses and is a major centre for horse and animal health.
- Newmarket Heath is a Site of Special Scientific Interest and is to be the largest area of mown grass in the world.
- Suffolk sheep are one of the most numerous sheep breeds in the world, having been exported all over the world.
- Suffolk is the only county in England with its own breed of sheep, cattle (Red Poll) and horse (Suffolk Horse)
- Bury St. Edmunds Abbey was one of the largest churches in England.
When I was about seven, the Port of Felixstowe was just a small dock exporting grain and now it the busiest container port in the UK and the eighth in Europe.
It is no surprise to me, that Felixstowe and Harwich want to be a Freeport, so they can expand further.
There have already been related news and media reports.
Freeport East Web Site
The Freeport East web site is at www.freeporteast.com.
Read these sections.
It is an ambitious vision. As someone, who believes we must innovate, this paragraph from the Innovation section strikes the right tone.
Beyond the energy sector, Freeport East will also contribute to wider innovation in the technology sector. Hutchison Ports is already working with Cambridge University and Three UK to develop innovative 5G applications. Hutchison Ports is also working with the New Anglia LEP, Tech East and BT’s research centre at Adastral Park on new telecommunications infrastructure. Freeport East will embed these technological innovations at its heart and help to make the UK a world leader in technological innovation
The web site, also talks about the ports becoming major centres for the development and servicing of renewable energy in the North Sea.
A Little Help From Their Friends
I notice that in some reports, they have joined forces with the University of Cambridge. As Cambridge colleges are big local landowners, this can only be to the benefit of the concept.
A Hydrogen Freeport
This article on the Eadt Anglian Daily Times is entitled Top Ports Could Be Powered By Hydrogen In Major Project.
The project is well-described in the article with this infographic, that shows how nuclear power from Siewell and wind power from the North Sea can come together to decarbonise shipping and the port.
This paragraph sums up the hydrogen project.
At its peak, the power project, which will be delivered in partnership with Ryze-Hydrogen and EDF, developers of the proposed Sizewell C nuclear power station, will produce 1GW of hydrogen – 20% of the 5GW target in the Prime Minister’s Ten Point Plan for a Green Industrial Revolution.
Suffolk is thinking big again!
It certainly does appear, that several ports are following the hydrogen route. On this blog I have mentioned Antwerp, Holyhead and Portsmouth recently.
So what will the hydrogen be used for?
The East Anglian article says this.
The clean fuel would be used to power port equipment, ships, trucks and trains.
Port Equipment
I think the interesting one is port equipment.
- The chairman of JCB is Anthony Bamford.
- His son; Jo Bamford owns Ryze Hydrogen.
- JCB have recently released a hydrogen-powered digger.
- JCB is mentioned on the infographic.
Could we be seeing a range of hydrogen-powered port equipment, that has been developed by JCB?
Other companies like Hyster are certainly developing hydrogen-powered port equipment.
Ships
Decarbonisation of ships is difficult, as they need a lot of power and it usually comes from that most noxious of fuels; bunker oil.
The Wikipedia entry for bunker oil, has a section called Environmental Issues, where this is said.
Emissions from bunker fuel burning in ships contribute to air pollution levels in many port cities, especially where the emissions from industry and road traffic have been controlled. The switch of auxiliary engines from heavy fuel oil to diesel oil at berth can result in large emission reductions, especially for SO2 and PM. CO2 emissions from bunker fuels sold are not added to national GHG emissions. For small countries with large international ports, there is an important difference between the emissions in territorial waters and the total emissions of the fuel sold.
A lot of work is being done to power ships with hydrogen.
Provide refuelling for hydrogen-powered ships and you’ll get the business.
Trucks
Diesel trucks hauling goods to and from ports contribute to the pollution in the port, but if they are powered by hydrogen, the pollution for workers and neighbours is less.
I can see some freight terminals adopting a policy of No Hydrogen – No Load, with hauliers.
In Holyhead Hydrogen Hub Planned For Wales, I talked about a hydrogen hub at Holyhead. Will the ports of Dover, Felixstowe and Immingham need to have hydrogen refuelling facilities to handle hydrogen trucks hauling goods between the island of Ireland and Europe?
Trains
It is my belief, that hydrogen freight locomotives will be developed, so Felixstowe will need facilities to fuel the trains.
Imagine two highly-automated ports at Felixstowe and Holyhead, both with large supplies of hydrogen.
- A hydrogen-powered freight train would link the two ports.
- Hydrogen-powered handling equipment would load and unload the containers.
How many trucks would that take off the roads between Holyhead and Felixstowe?
Conclusion
The Port of Felixstowe is going to use hydrogen to become more efficient and zero-carbon, and make it more attractive to shippers wanting to pay more than lip-service to decarbonisation.
The EU have constantly accused Boris of turning the UK into Singapore-on-Thames!
But here we are creating Singaport-on-the-Haven.
The EU has freeports, so I guess it’s OK.
Is Sizewell The Ideal Site For A Fleet Of Small Modular Nuclear Reactors?
As someone who spent forty years in project management, the Small Modular Nuclear Reactor or SMR could be a project manager’s dream.
Suppose you were putting a fleet of SMRs alongside Sizewell B.
This Google Map shows the current Sizewell site.
Sizewell A power station, with Sizewell B to its North, is on the coast.
This second Google Map shows the power stations to an enlarged scale.
Note the white dome in the middle of Sizewell B.
Sizewell A
Sizewell A power station was shut down at the end of 2006 and is still being decommissioned, according to this extract from Wikipedia.
The power station was shut down on 31 December 2006. The Nuclear Decommissioning Authority (NDA) is responsible for placing contracts for the decommissioning of Sizewell A, at a budgeted cost of £1.2 billion. Defuelling and removal of most buildings is expected to take until 2034, followed by a care and maintenance phase from 2034 to 2092. Demolition of reactor buildings and final site clearance is planned for 2088 to 2098.
Only a few of those, reading this post, will be around to see the final end of Sizewell A.
Note that the size of the Sizewell A site is 245 acres.
It appears to me, that if any power station will be able to be built on the cleared site of Sizewell A, until the late 2080s or 2090s.
Sizewell B
Sizewell B power station opened in 1995 and was originally planned to close in 2035. The owner; EDF Energy, has applied for a twenty-year extension to 2055.
Sizewell C
Sizewell C power station is currently under discussion.
- It will be built by the French, with the help of Chinese money.
- It will have an output of 3260 MW or 3.26 GW.
- It will cost £18 billion.
- It will take twelve years to build.
This Google Map shows Sizewell B and the are to the North.
I would assume it will be built in this area.
A Fleet Of Small Modular Nuclear Reactors
These are my thoughts on building a fleet of SMRs at Sizewell instead of the proposed Sizewell C.
Land Use
In Rolls-Royce signs MoU With Exelon For Compact Nuclear Power Stations, I gave these details of the Rolls-Royce design of SMR.
- A Rolls-Royce SMR has an output of 440 MW.
- The target cost is £1.8 billion for the fifth unit built
- Each SMR will occupy 10 acres.
- Eight SMRs would need to be built to match the output of Hinckley Point C, which will occupy 430 acres.
It looks on a simple calculation, that even if the SMRs needed fifteen acres, the amount of land needed would be a lot less.
Connection To The National Grid
The transmission line to the National Grid is already in place.
This Google Map shows the sub-station, which is to the South-West of Sizewell A.
From Sizewell, there is a massive twin overhead line to Ipswich.
This Google Map shows the overhead line as it crosses Junction 53 of the A14 to the West of Ipswich.
The pylons are in the centre of the map, with the wires going across.
The line has been built for a massive amount of nuclear power at Sizewell.
The Sizewell Railhead
This Google Map shows the railhead at Sizewell.
It can also be picked out in the South West corner of the first map.
- The railhead is used to take out spent fuel for processing.
- In the past, it brought in construction materials.
- Wikipedia suggests if the Sizewell C is built, the might be a new railhead closer to the site.
- If a fleet of SMRs were to be built, as the modules are transportable by truck, surely they could be move in by rail to avoid the roads in the area.
- I am an advocate of reinstating the railway from Saxmundham to Aldeburgh, as this would be a way of doubling the frequency on the Southern section of the East Suffolk Line between Saxmundham and Ipswich stations.
I hope that whatever is built at Sizewell, that the rail lines in the area is developed to ease construction, get workers to the site and improve rail services on the East Suffolk Line.
Building A Fleet Of SMRs
One of the disadvantages of a large nuclear power station, is that you can’t get any power from the system until it is complete.
This of course applies to each of the individual units, but because they are smaller and created from a series of modules built in a factory, construction of each member of the fleet should be much quicker.
- Rolls-Royce are aiming for a construction time of 500 days, from the fifth unit off the production line.
- That would mean, that from Day 501, it could be producing power and earning money to pay for its siblings.
- If the eight units were built in series, that would take eleven years to build a fleet of eight.
But as anybody, who has built anything even as humble as a garden shed knows, you build anything in a series of tasks, starting with the foundations.
I suspect that if a fleet were being built, that construction and assembly would overlap, so the total construction time could be reduced.
That’s one of the reasons, I said that building a fleet could be a project manager’s dream.
I suspect that if the project management was top-class, then a build time for a fleet of eight reactors could be nine years or less.
Resources are often a big problem in large projects.
But in a phased program, with the eight units assembled in turn over a number of years, I think things could be a lot easier.
Financing A Fleet Of SMRs
I think that this could be a big advantage of a fleet of SMRs over a large conventional large nuclear power station.
Consider
- I said earlier, that as each unit was completed, it could be producing power and earning money to pay for its siblings.
- Hinckley Point C is budgeted to cost £18 billion.
- Eight Rolls-Royce SMRs could cost only £14.4 billion.
I very much feel that, as you would get a cash-flow from Day 500 and the fleet costs less, that the fleet of smaller stations is easier to finance.
Safety
SMRs will be built to the same safety standards as all the other UK reactors.
In this section on Wikipedia this is said about the Rolls-Royce SMR.
Rolls-Royce is preparing a close-coupled three-loop PWR design, sometimes called the UK SMR.
PWRs or pressurised water reactors are the most common nuclear reactors in the world and their regulation and safety is well-understood.
This is from the History section of their Wikipedia entry.
Several hundred PWRs are used for marine propulsion in aircraft carriers, nuclear submarines and ice breakers. In the US, they were originally designed at the Oak Ridge National Laboratory for use as a nuclear submarine power plant with a fully operational submarine power plant located at the Idaho National Laboratory. Follow-on work was conducted by Westinghouse Bettis Atomic Power Laboratory.
Rolls-Royce have a long history of building PWRs, and Rolls-Royce PWRs have been installed in all the Royal Navy’s nuclear submarines except the first. The Royal Navy’s second nuclear submarine; HMS Valiant, which entered service in 1966, was the first to be powered by a Rolls-Royce PWR.
How much of the design and experience of the nuclear submarine powerplant is carried over into the design of the Rolls-Royce SMR?
I don’t know much about the safety of nuclear power plants, but I would expect that if there was a very serious accident in a small reactor, it would be less serious than a similar accident in a large one.
Also, as the reactors in a fleet would probably be independent of each other, it is unlikely that a fault in one reactor should affect its siblings.
Local Reaction
I lived in the area, when Sizewell B was built and I also went over Sizewell A, whilst it was working.
From personal experience, I believe that many in Suffolk would welcome a fleet of SMRs.
- Sizewell B brought a lot of employment to the area.
- House prices rose!
- Both Sizewell A and B have been well-run incident-free plants
Like me, some would doubt the wisdom of having a Chinese-funded Sizewell C.
Conclusion
Big nuclear has been out-performed by Rolls-Royce
