HS2 To Trial New Building Method Which Could Provide Carbon-Free Energy
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is the first three paragraphs.
Part of HS2’s Innovation programme, an HS2 building site in London is to become a test bed for a new building method which could ultimately provide carbon-free energy to stations on the new high speed route.
The new approach will be trialled by contractors Mace Dragados at the project’s Euston station site in London and will draw ground heat up through the foundations of a newly-built construction site office.
Developed by Keltbray, the innovative new technology is estimated to harness enough energy to supply 80% of the building’s heating and hot water needs.
It’s an incredibly simple, but extremely powerful idea, that revolutionises heating, cooling and hot water in buildings.
Read the article and then read the brochure on the Keltbray web site.
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.
Expansion Plan To Take World’s Biggest Battery Storage Project To 3GWh Capacity
The title of this post, is the same as that of this article on Energy Storage News.
These are the first two paragraphs.
Plans to nearly double the output and capacity of the world’s biggest battery energy storage system (BESS) project to date have been announced by its owner, Vistra Energy.
The Texas-headquartered integrated utility and power generation company said it wants to add another 350MW/1,400MWh BESS to the Moss Landing Energy Storage Facility in California’s Monterey Bay.
The project is based at the Moss Landing Power Plant, which was once the largest power plant in the state of California, with a generation capacity of 2560 MW.
There appear to be three phases.
- Phase 1 is 300MW/1,200MWh and went online at the end of 2020
- Phase 2 is 100MW/400MWh and went online in August 2021.
- Phase 3 will be 350MW/1,400MWh.
This gives a maximum power output of 750 MW and prospective total capacity of 3 GWh. At full power, the battery could supply 750 MW for four hours.
For comparison, the two Scottish batteries I talked about in Amp Wins Consent For 800MW Scots Battery Complex, have a combined output of 800 MW and a total capacity of 1600 MWh, which would give a full power run of two hours.
Could the difference be that Scotland has 9.3 GW of installed windpower, whereas the much larger California has only 6 GW?
Both Scotland and California also have some pumped storage power stations.
- Drax Group who own the 7.1 GWh Cruachan power station, plan to increase its generating capacity from 440MW to 1040MW.
- California has two larger stations at Castaic and Helms.
- After writing about the Western HVDC Link in Amp Wins Consent For 800MW Scots Battery Complex, I wonder if when the wind is blowing in Scotland and it isn’t in Wales, that electricity can be exported from Scotland to Wales for storage.
This all shows the complex integrated nature of electricity networks.
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.
- The Hunterston A and Hunterston B nuclear power stations, which are both being decommissioned.
- Hunterston B only shut down on the 7th of January, this year.
- 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.
- The Clackmannanshire Bridge down the Western side of the map.
- The Kincardine Substation to the East of the bridge close to the shore of the River Forth.
- 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.
- The red arrow indicates the Flintshire Bridge HVDC converter station, which is the Southern end of the Western HVDC Link.
- The Borderlands Line between Liverpool and Chester, runs North-South to the East of the convertor station.
- 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.
- To the West of the converter station, just to the East of the A 548 road, is the 498 MW Deeside power station.
- 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.
- The two power stations burn gas from Liverpool Bay.
- 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!
BHP To Trial Battery Locos On Pilbara Iron Ore Network
The title of this post, is the same as that of this article on Railway Gazette.
The article summarised all the battery-electric locomotives ordered to bring the iron ore to the coast by mining companies; BHP, Fortescue, Rio Tinto and Roy Hill.
The article indicates some of the innovative operations that will be tried. This is a sentence from the article.
A key element will be to assess the potential for capturing regenerated braking energy on the loaded downhill runs, and storing it to power empty trains back uphill to the mines.
I would hope that the South Wales Metro, the Buxton branch and the East Kilbride branch will use similar energy conservation techniques.
Spanish Consortium Forms For $4.4 Billion Green Hydrogen Investment
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This paragraph outlines the project.
A thirty-three company consortium, called the Spanish Hydrogen Network (Shyne) will be investing into a spectrum of green hydrogen technologies, including the installation of 500 megawatts of renewable H2 capacity by 2025. From there, the capacity will increase to 2 gigawatts by 2030. This represents half of the Spanish government’s goal for the entire country by that year, which is 4 gigawatts of capacity.
The article says this about the creation of hydrogen hubs.
The green hydrogen project’s goal is to “generate an ecosystem that connects” three H2 hubs.
The goal of the project is to develop an ecosystem in which three planned industrial H2 hubs in the Murcia, Catalonia and Basque regions will be connected. The project is also meant to support the development of two new innovation hubs in Castile-La Mancha and Madrid and will target the development of solid-oxide electrolyzers and photoelectrocatalysis.
Note that photoelectrocatalysis is the direct production of hydrogen from solar energy.
Exploring Germany Under The Latest Travel Rules
Because of the lack of travel brought about by the Covids, I’ve built up a list of places that I want to visit in Germany.
- Hamburg to see the Siemens Gamesa ETES energy storage and see how the Alstom Coradia iLint hydrogen train is getting on.
- Karlsruhe to see the newly-opened tram-tunnel in the city.
- Stuttgart to see how the construction work for Stuttgart 21 is faring and Alstom’s new battery trains.
- The Lake Constance Belt Railway.
The latest rules mean that travelling back to the UK is easy, so if I chose a route that allowed me to visit all the places I want from say a hotel in somewhere worth visiting like Stuttgart, would it be possible to book an appropriate stay there as a package?
Would this mean all the paperwork going to Germany would be handled by someone else, so if a mistake was made, it’s not my fault?
How Defunct Coal Mines Could Heat UK Homes
The title of this post, is the same as that of this article on Mining Technology.
This is the introductory paragraph.
In a country with no operational coal mines, the UK Coal Authority has proposed to once again turn these operations to heating homes and businesses. But this time, they will not provide coal for burning. The plan, to take warm water from flooded mines, would turn an environmental problem into a community solution, and the idea is spreading.
The reason, I’m posting this is two-fold.
There was a report on this edition of Countryfile, which should be available until the end of 2022. The relevant section starts at 38.5 minutes into the program.
Charlotte Adams is featured in this report and the Countryfile program. I first came across Charlotte and her fascinating work at a lecture in 2018, which I wrote about in Can Abandoned Mines Heat Our Future?
Energy Storage Could Emerge As The Hottest Market Of 2022
The title of this post, is the same as that of this article on Nasdaq.
This is the introductory paragraph.
A few years ago, battery energy storage began drawing attention as what one industry executive at the time called the Holy Grail of renewable energy. In the years since, EVs have stolen the spotlight but now battery storage is back, larger than life and, quite likely, twice as expensive.
I would wholeheartedly agree.
Although, I do think, that some of the major players over the next few years will not be based on lithium-ion batteries.
I have invested in Gravitricity and Rheenergise and would have invested in Highview Power, if I had had the chance.
My stockbroker has also invested some of my pension in energy storage and battery funds.
Lithium In A California Lake Could Help U.S. Gain Energy Autonomy
The title of this post, is the same as that of this article on NBC News.
This is the introductory paragraph.
The ingredient crucial to electric car batteries is found in the brine of the Salton Sea, a once-busy recreation spot that fell into decay because of toxic runoff.
So where is the Salton Sea?
This Google Map shows the Salton Sea in the middle of the Californian desert.
It looks like a rather bleak hot place to me.
But if we can extract lithium out of little Cornwall, surely the Yanks can extract it from a dying lake.
