Porterbrook Raises £250m Of New Green Private Placements
The title of this post, is the same as that of this article on Railway Gazette.
This is the sub-heading.
Porterbrook, the UK’s leading rolling stock financier and asset management company, is delighted to announce the successful closing of its £250m Private Placement.
These are the first two paragraphs.
The transaction, which includes existing and new investors, has enabled the company to extend its debt maturity profile at attractive pricing and further diversify its investor base of US, UK and Swiss institutions.
Porterbrook owns a quarter of the national passenger rail fleet, and in recent years has significantly diversified its portfolio including taking ownership of the Long Marston Rail Innovation Centre in Warwickshire, confirming a 49% stake in Brodie Engineering in Kilmarnock, and financing the redevelopment of Bletchley Depot for West Midland Trains.
We must be doing something right on the railways, if US, UK and Swiss institutions are prepared to back them financially.
But then Aviva, who were formerly Norwich Union, backed Greater Anglia’s new Swiss trains.
Conclusion
Despite what some might think, it would appear that green investments aren’t all bad.
SSE Launches £10m Hydro Community Benefit Fund
The title of this post, is the same as that of this article on Project Scotland.
This is the sub-heading.
SSE has launched a new £10 million hydro community benefit fund aimed at supporting projects within areas that host its existing hydro power infrastructure across Scotland.
These paragraphs fill in some detail.
The launch comes following the 80th anniversary of the hydro-electric development (Scotland) act of 1943, which enabled the North of Scotland Hydro-Electric Board (NoSHEB) to transform the way people lived and worked through the build of 54 power stations, 78 dams, and over 300km of underground tunnels.
SSE Renewables recently commissioned a report by Biggar Economics which found that the capital investment in hydro over the 80-year period since 1943 is £7.5 billion, supporting over 10,000 jobs annually in Scotland including 5,519 in the Highlands and Islands.
The new hydro community fund will see investment in local communities continue, with SSE Renewables having consulted with community council areas to establish key priorities.
Priorities include improvements to sustainable community transport, affordable housing, growth of small businesses and social enterprises, improvement of community assets and infrastructure, and a focus on community physical and mental well-being through community arts, culture, sports, and recreation.
If the new fund is as successful as the first, I can’t see thee being many complaints.
UK To Fund Hydro Energy Storage Projects
The title of this post, is the same as that of this article on The Times.
This is the sub-heading.
New infrastructure aims to help balance the electricity system after the rapid growth in renewables
These three paragraphs infrastructure the article.
Projects that use water to store and release energy are to be given government support, in an attempt to help manage the volatility in supply and demand as more green power enters the grid.
From next year, pumped hydro storage projects will be able to apply for government subsidies, which will be provided via a “cap and floor” mechanism. These would guarantee revenues if prices drop below a certain floor but prevent providers from charging above a ceiling when power prices are high.
Like other government support schemes, any cost will be levied on energy bills, while consumers will be paid back any money generated above the cap. It is yet to be decided precisely how the cap and floor will be set.
I feel it is reasonable to expect the system to be a success, as a similar system is used for interconnectors and this article on Offshore Energy is entitled Over $86 million To Be Split Between UK and Belgium Consumers As 1 GW Subsea Interconnector’s ‘Remarkable’ Revenues Exceed Ofgem’s Cap.
It looks like Ofgem played this right for interconnectors and the Nemo Link is making a substantial payment.
It will be interesting to see what happens when “cap and floor” contracts are assigned.
This move by Ofgem will probably have effects in two areas.
- SSE, Statera and Statkraft, who are typically developing systems at the high end with a size of about 1.5 GW/25 GWh could find money is easier to come by.
- At the lower end, companies like Highview Power, who have systems of 50 MW/300 MWh and 200 MW/2.5 GWh under development, will also benefit.
My Control Engineering thoughts are leaning towards the 200 MW/2.5 GWh systems being the popular ones. Especially as they would appear to be close to the right size to support a 1 GW wind farm for two hours.
A Highview Power Two-Hour Liquid Air Battery could fit nearly with a fleet of Two-Hour BESS.
It should be noted that CAF use a little-and-large approach to theit battery-electric trams in the West Midlands.
A large lithium-ion battery is the main storage device.
A supercapacitor handles the high-frequency response and keeps the power steady.
Pairing a Highview Power Two-Hour Liquid Air Battery and a Two-Hour BESS could achieve the same performance and possibly result in some cost savings.
Equinor Acquires Minority Stake In Ørsted, Becomes Second-Largest Shareholder
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Norway-headquartered Equinor has acquired a 9.8 per cent minority stake in Denmark’s Ørsted, making it the second-largest shareholder behind the Danish state, which holds a controlling stake in the company.
These are the first two paragraphs.
According to Equinor, the company is supportive of Ørsted’s strategy and management and is not seeking board representation.
“Equinor has a long-term perspective and will be a supportive owner in Ørsted. This is a counter-cyclical investment in a leading developer, and a premium portfolio of operating offshore wind assets”, said Anders Opedal, CEO of Equinor.
Could it also be two Scandinavian companies getting together to put up a stronger front to outside interests?
Are they frightened of the actions that might be taken by Great British Energy and by the Germans with their massive thirst for hydrogen?
Norway Plans EUR 3 Billion Subsidy For Floating Offshore Wind
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Norwegian government has proposed NOK 35 billion (approximately EUR 3 billion) for a support scheme dedicated towards the first commercial floating offshore wind tender within the Vestavind F and Vestavind B areas.
These are the first two paragraphs.
According to the press release, the government is making progress in following up on its ambitious plan to allocate project areas for 30 GW of offshore wind by 2040.
Norway plans to conduct the next tendering round for offshore wind in 2025. After that, the government intends to hold regularly scheduled tendering rounds and state aid competitions leading up to 2040.
The original press release is called A Responsible Approach To Floating Offshore Wind.
Some politicians and green sceptics might not call three billion euros responsible.
I do suspect that Great British Energy will have to deal in this size of numbers to be able to compete with the Norwegians.
We’ll have to work hard to meet our target of 100 GW by 2040.
But at least as the UK’s target is higher, does that mean that the target should be easier. Or do we have more suitable sea?
There Are Only Three Large Offshore Wind Farms In Contracts for Difference Allocation Round 6
This document from the Department of Business, Industry and Industrial Strategy lists all the Contracts for Difference Allocation Round 6 results for the supply of zero-carbon electricity.
The wind farms are.
- Green Volt – 400 MW – Floating – Claims to be “The first commercial-scale floating offshore windfarm in Europe”.
- Hornsea Four – 2,400 MW – Fixed – Ørsted
- East Anglia Two – 963 MW – Fixed – Iberdrola
Is this what misgovernment expected, when they raised the budget in July 2024, as I wrote about in UK Boosts Sixth CfD Auction Budget, Earmarks GBP 1.1 Billion For Offshore Wind.
Perhaps, some developers held back until government policy is clearer?
Funding Awarded For Study On Hydrogen Storage Potential In The East Midlands
The title of this post, is the same as that of this article on the British Geological Survey.
This is the sub-heading.
A new study has been awarded funding to explore the underground hydrogen storage potential in the East Midlands.
These are the first three paragraphs.
East Midlands Storage (EMstor), a consortium led by Cadent and partnered with BGS, Star Energy Group, Net Zero Strategy and the University of Edinburgh, has been awarded discovery funding by Ofgem’s Strategic Innovation Fund to undertake a new study to evaluate geological storage potential in the East Midlands.
The EMstor study is the first of its kind in the region. It will undertake a feasibility assessment of the East Midlands’ geology to evaluate its potential to host storage technologies, allowing expansion of Cadent’s proposed 100 per cent hydrogen pipeline.
The East Midlands has numerous depleted oil reservoirs, which may have potential to store hydrogen. The study will characterise the potential geological reservoir to establish if it is suitable for hydrogen storage at scale in the local area.
The oilfields of the East Midlands Oil Province have their own Wikipedia entry, which gives full details of the dozens of small oil fields in the area.
- It may not be the world’s largest oil resource, but it certainly helped us during the Second World War.
- Experienced Texan oil-men were even imported, to help boost production.
- It used to be possible to spot the occasional lonely nodding donkey, as you passed through the area.
Surely, if some of the oilfields can be converted to hydrogen stores, this would be very useful.
‘Windiest Part Of The UK’ Could Power Nearly 500,000 Homes
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Power is flowing from the Shetland Isles to mainland Britain for the first time as the UK’s most productive onshore windfarm comes on stream.
These are the first two paragraphs.
SSE says its 103-turbine project, known as Viking, can generate 443 megawatts (MW) of electricity, enough to power nearly 500,000 homes.
Shetland is the windiest part of the UK, which means it will be rare for the blades, which reach a massive 155m at their tip, not to be spinning.
Note.
- SSE has built a 160-mile long undersea cable to carry the power from Viking to Noss Head, near Wick, on the Scottish mainland.
- The company said it has invested more than £1bn in the windfarm and cable projects.
- SSE plans to plough another £20bn into renewables by the end of the decade.
Companies don’t invest billions and banks don’t lend billions, unless they know they’ll get a return, so the finance for this billion pound project must be sound.
A simple calculation, shows why they do.
- According to Google, the electricity for the average house costs £1926.24 per year.
- 500,000 houses would spend £963,120,000 per year.
Google says this about the life of a wind farm.
The average operational lifespan of a wind turbine is 20–25 years, but some turbines can last up to 30 years.
If the wind farm lasts 25 years, then it will generate something like £24 billion over its lifetime.
It looks to me, that SSE have borrowed a billion and will get almost as much as that back every year.
SSE also have the experience to keep the turbines turning and the distribution network sending electricity to the Scottish mainland.
I have some further thoughts.
What Happens If Scotland Can Get Cheaper Electricity From Its Own Wind Farms?
Shetland’s turbines can be switched off, but that is effectively throwing away electricity that can be generated.
Any spare electricity can also be diverted to an electrolyser, so that the following is produced.
- Hydrogen for transport, rocket fuel for SaxaVord Spaceport and to decarbonise houses and businesses.
- Oxygen for rocket fuel for SaxaVord Spaceport and for fish farms.
Hydrogen may also be exported to those that need it.
Project Orion
Project Orion is Shetland’s master plan to bring all the energy in and around the Shetland Islands together.
This document on the APSE web site is entitled Future Hydrogen Production In Shetland.
This diagram from the report shows the flow of electricity and hydrogen around the islands, terminals and platforms.
Note these points about what the Shetlanders call the Orion Project.
- Offshore installations are electrified.
- There are wind turbines on the islands
- Hydrogen is provided for local energy uses like transport and shipping.
- Oxygen is provided for the fish farms and a future space centre.
- There is tidal power between the islands.
- There are armadas of floating wind turbines to the East of the islands.
- Repurposed oil platforms are used to generate hydrogen.
- Hydrogen can be exported by pipeline to St. Fergus near Aberdeen, which is a distance of about 200 miles.
- Hydrogen can be exported by pipeline to Rotterdam, which is a distance of about 600 miles.
- Hydrogen can be exported by tanker to Rotterdam and other parts of Europe.
It looks a very comprehensive plan, which will turn the islands into a massive hydrogen producer.
Orion And AquaVentus
This video shows the structure of AquaVentus, which is the German North Sea network to collect hydrogen for H2ercules.
I clipped this map from the video.
Note.
- There is a link to Denmark.
- There appears to be a undeveloped link to Norway.
- There appears to be a link to Peterhead in Scotland.
- There appears to be a link to just North of the Humber in England.
- Just North of the Humber are the two massive gas storage sites of Aldbrough owned by SSE and Rough owned by Centrica.
- There appear to be small ships sailing up and down the East Coast of the UK. Are these small coastal tankers 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.
This map is only the start and I feel, there would be nothing to stop the connection of the Orion and AquaVentus networks.
SaxaVord Spaceport
SaxaVord Spaceport is now a reality, in that it licensed and tests are being undertaken.
Energy In – Hydrogen And Carbon Dioxide Out
This article was inspired by this article in the Sunday Times, which is entitled ‘It’s A Slog’: Life Inside Britain’s Last Coal Power Station.
The article is about Ratcliffe-on-Soar power station, which is next to East Midlands Parkway station.
This is the first paragraph of the station’s Wikipedia entry.
Ratcliffe-on-Soar Power Station is a coal-fired power station owned and operated by Uniper at Ratcliffe-on-Soar in Nottinghamshire, England. Commissioned in 1968 by the Central Electricity Generating Board, the station has a capacity of 2,000 MW. It is the last remaining operational coal-fired power station in the UK, and is scheduled to close in September 2024.
I took these pictures of the power station in 2019.
Ratcliffe-on-Soar is the last of a number of large coal-fired power stations, that were built in the area, mainly along the River Trent.
- Rugeley – 600 MW – 1961
- Drakelow – 1630 MW – 1964
- Willington – 800 MW – 1962
- Castle Donington – 600 MW – 1958
- Ratcliffe-on-Soar – 2000 MW – 1968
- High Marnham – 1000 MW – 1959
- Cottam – 2000 MW – 1968
- West Burton – 2000 MW – 1968
Note.
- The date is the commissioning date.
- That is 10,630 MW of electricity.
- There are also a few large gas-fired power stations along the river, that are still operating.
- Both coal and gas-fired stations use the water from the River Trent for cooling.
At the mouth of the river, there is the Keadby cluster of gas-fired power stations.
- Keadby 1 – 734 MW – 1996
- Keadby 2 – 849 MW – 2023
- Keadby 3 – 910 MW – 2027
- Keadby Hydrogen – 900 MW – 2030
Note.
- The date is the commissioning date.
- That is 3,393 MW of electricity.
- Keadby 2 is the most efficient CCGT in the world.
- Keadby 3 will be fitted with carbon capture.
- Keadby 2 has been designed to be retrofitted with carbon capture.
- Keadby Hydrogen will be fuelled by zero-carbon hydrogen.
As the years progress, I can see the Keadby cluster of power stations becoming a large zero-carbon power station to back-up wind farms in the North Sea.
- Hydrogen power stations will emit no carbon dioxide.
- Carbon dioxide from all gas-fired stations will be captured.
- Some carbon dioxide will be sold on, to companies who can use it, in industries like construction, agriculture and chemical manufacture.
- The remaining carbon dioxide will be stored in depleted gas fields.
As technology improves, more carbon dioxide will be used rather than stored.
Other Power Sources In The Humberside Area
In the next few sub-sections, I will list the other major power sources in the Humberside area.
Drax Power Station
Drax power station is a shadow of its former self, when it was one of the power stations fed by the newly discovered Selby coalfield.
These days it is a 2,595 MW biomass-fired power station.
Eastern Green Link 2
Eastern Green Link 2 will be a 2 GW interconnector between Peterhead in Scotland and Drax.
It is shown in this map.
Note.
- Most of the route is underwater.
- It is funded by National Grid.
- Contracts have been signed, as I talk about in Contracts Signed For Eastern Green Link 2 Cable And Converter Stations.
- It is scheduled to be completed by 2029.
This interconnector will bring up to 2 GW of Scottish wind-generated electricity to Drax and Humberside.
Drax has the substations and other electrical gubbins to distribute the electricity efficiently to where it is needed.
2 GW could also reduce the amount of biomass used at Drax.
In the long term, if the concept of the four Eastern Green Links is successful, I could see another Eastern Green Link to Drax to replace imported biomass at Drax.
I also, don’t see why a smaller Drax can’t be run on locally-sourced biomass.
Solar Farms And Batteries Along The River Trent
As the coal-fired power stations along the River Trent are demolished, solar farm developers have moved in to develop large solar farms.
Salt End Power Station And Chemical Works
These two paragraphs from the Wikipedia entry for Salt End describes the hamlet and its power station and chemical works.
Salt End or Saltend is a hamlet in the East Riding of Yorkshire, England, in an area known as Holderness. It is situated on the north bank of the Humber Estuary just outside the Hull eastern boundary on the A1033 road. It forms part of the civil parish of Preston.
Salt End is dominated by a chemical park owned by PX group, and a gas-fired power station owned by Triton Power. Chemicals produced at Salt End include acetic acid, acetic anhydride, ammonia, bio-butanol, bio-ethanol, ethyl acetate (ETAC) and ethylene-vinyl alcohol copolymer (EVOH) with animal feed also being produced on site.
I wonder, if running the complex on hydrogen would give cost and marketing advantages.
Aldbrough Hydrogen Storage Facility
This page on the SSE Thermal web site is entitled Plans For World-Leading Hydrogen Storage Facility At Aldbrough.
This is the most significant paragraph of the page, that is definitely a must-read.
With an initial expected capacity of at least 320GWh, Aldbrough Hydrogen Storage would be significantly larger than any hydrogen storage facility in operation in the world today. The Aldbrough site is ideally located to store the low-carbon hydrogen set to be produced and used in the Humber region.
This is a hydrogen storage facility for a much wider area than Humberside.
Rough Gas Storage Facility
This is the first paragraph of the Wikipedia entry for the Rough Gas Storage Facility.
Rough is a natural gas storage facility under the North Sea off the east coast of England. It is capable of storing 100 billion cubic feet of gas, nearly double the storage capacities in operation in Great Britain in 2021.
In Wood To Optimise Hydrogen Storage For Centrica’s Rough Field, I describe Centrica’s plans to convert the Rough gas storage into a massive hydrogen storage.
The Location Of Aldbrough Gas Storage, Rough Gas Storage, Salt End And Easington Gas Terminal
This Google Map shows between Salt End and the coast.
Note.
- The river crossing the South-West corner of the map is the Humber.
- Salt End with its power station and chemical works is on the North Bank of the Humber, where the river leaves the map.
- Aldbrough Gas Storage is marked by the red arrow at the top of the map.
- Easington Gas Terminal is in the South-East corner of the map.
- According to Wikipedia, gas flows into and out of the Rough Gas Storage are managed from Easington.
Looking at the map, I feel that the following should be possible.
- The two gas storage sites could be run together.
- Salt End power station and the related chemical works could run on hydrogen.
- Salt End will always have a reliable source of hydrogen.
- This hydrogen could be green if required.
All the chemical works at Salt End, could be run on a zero-carbon basis. Would this mean premium product prices? Just like organic does?
Enter The Germans
The Germans have a huge decarbonisation problem, with all their coal-fired power stations and other industry.
Three massive projects will convert much of the country and industry to hydrogen.
- H2ercules, which is a project of OGE and RWE, will create a hydrogen network to bring hydrogen, to where it is needed.
- In Uniper To Make Wilhelmshaven German Hub For Green Hydrogen; Green Ammonia Import Terminal, I describe how Uniper are going to build a hydrogen import terminal at Wilhelmshaven.
- AquaVentus is an RWE project that will use 10.3 GW of offshore wind power in German territorial waters to create a million tonnes per year of green hydrogen.
These would appear to be three of Europe’s largest hydrogen projects, that few have ever heard of.
AquaVentus And The UK
This video shows the structure of AquaVentus.
I clipped this map from the video.
Note.
- The thick white line running North-West/South-East is the spine of AquaVentus, that delivers hydrogen to Germany.
- There is a link to Denmark.
- There appears to be an undeveloped link to Norway.
- There appears to be an undeveloped link to Peterhead in Scotland.
- There appears to be a link to just North of the Humber in England.
- Just North of the Humber are the two massive gas storage sites of Aldbrough owned by SSE and Brough owned by Centrica.
- There appear to be small ships sailing up and down the East Coast of the UK. Are these small coastal tankers, that are distributing the hydrogen to where it is needed?
In the last century, the oil industry, built a substantial oil and gas network in the North Sea.
It appears now the Germans are leading the building of a substantial hydrogen network in the North Sea.
These are my thoughts about development of the AquaVentus network.
Hydrogen Production And AquaVentus
This RWE graphic shows the layout of the wind farms feeding AquaVentus.
Note.
- There is a total of 10.3 GW.
- Is one of the 2 GW web sites on the UK-side of AquaVentus, the 3 GW Dogger Bank South wind farm, which is being developed by RWE?
- Is the 0.3 GW wind farm, RWE’s Norfolk wind farm cluster, which is also being developed by RWE?
Connecting wind farms using hydrogen pipelines to Europe, must surely mitigate the pylon opposition problem from Nimbys in the East of England.
As the AquaVentus spine pipeline could eventually connect to Peterhead, there will be other opportunities to add more hydrogen to AquaVentus.
Hydrogen Storage And AquaVentus
For AquaVentus to work efficiently and supply a large continuous flow of hydrogen to all users, there would need to be storage built into the system.
As AquaVentus is around 200 kilometres in length and natural gas pipelines can be up to 150 centimetres in diameter, don’t underestimate how much hydrogen can be stored in the pipeline system itself.
This page on the Uniper web site is entitled Green Wilhelmshaven: To New Horizons.
This is a sentence on the page.
Access to local hydrogen underground storage at the Etzel salt cavern site.
An Internet search gives the information, that Etzel gas storage could be developed to hold 1 TWh of hydrogen.
That would be enough hydrogen to supply 10 GW for a hundred hours.
Note that the UK branch of AquaVentus reaches the UK, just to the South of the massive hydrogen storage facilities at Aldbrough and Rough.
It would appear that both Germany and the UK are connected to AquaVentus through substantial storage.
I am certain, that all country connections to AquaVentus will have substantial storage at the country’s hydrogen terminal.
AquaDuctus
This would appear to be the first part of the AquaVentus network and has its own web site.
The web site is entitled Nucleus Of A Offshore Hydrogen Backbone.
These are the first two paragraphs.
The project partners are focusing on a scalable, demand-driven infrastructure: By 2030, AquaDuctus will connect the first large hydrogen wind farm site, SEN-1, with a generation capacity of approximately one gigawatt. SEN-1 is located in the German EEZ in the northwest of Helgoland. The pipeline will transport at a length of approx. 200 km green hydrogen produced from offshore wind to the German mainland and from there to European consumers via the onshore hydrogen infrastructure.
In the next project stage, AquaDuctus will be extended to the remote areas of the German exclusive economic zone towards the tip of the so-called duck’s bill. By that, additional future hydrogen wind farm sites will be connected. Along its way AquaDuctus will provide interconnection points with the opportunity for linking of adjacent national offshore hydrogen infrastructures originating from Denmark, Norway, the Netherlands, Belgium and United Kingdom which opens the door for Europe-wide offshore hydrogen transport by pipeline.
There is also an interactive map, that gives more details.
This paragraph explains, why the Germans have chosen to bring the energy ashore using hydrogen, rather than traditional cables.
Recent studies show that offshore hydrogen production and transport via pipelines is faster, cheaper, and more environmentally friendly than onshore electrolysis with a corresponding connection of offshore wind turbines via power cables. The German federal government has also recognized this advantage and has clearly expressed its intention to promote offshore hydrogen production in the North Sea.
I suspect, that some UK offshore wind farms will use the same techniques.
Hydrogen Production For The UK
Electrolysers will probably be built along the East Coast between Peterhead and Humberside and these will feed hydrogen into the network.
- Some electrolysers will be offshore and others onshore.
- Turning off windfarms will become a thing of the past, as all surplus electricity will be used to make hydrogen for the UK or export to Europe.
- Until needed the hydrogen will be stored in Albrough and Rough.
Backup for wind farms, will be provided using hydrogen-fired power stations like Keadby Hydrogen power station.
Financial Implications
I reported on Rishi Sunak’s Manifesto Speech, which he made on June 11th. This is an extract
This document on the Policy Mogul web site is entitled Rishi Sunak – Conservative Party Manifesto Speech – Jun 11.
These are three paragraphs from the speech.
We don’t just need military and border security. As Putin’s invasion of Ukraine has shown, we need energy security too. It is only by having reliable, home-grown sources of energy that we can deny dictators the ability to send our bills soaring. So, in our approach to energy policy we will put security and your family finances ahead of unaffordable eco zealotry.
Unlike Labour we don’t believe that we will achieve that energy security via a state-controlled energy company that doesn’t in fact produce any energy. That will only increase costs, and as Penny said on Friday there’s only one thing that GB in Starmer and Miliband’s GB Energy stands for, and that’s giant bills.
Our clear plan is to achieve energy security through new gas-powered stations, trebling our offshore wind capacity and by having new fleets of small modular reactors. These will make the UK a net exporter of electricity, giving us greater energy independence and security from the aggressive actions of dictators . Now let me just reiterate that, with our plan, we will produce enough electricity to both meet our domestic needs and export to our neighbours. Look at that. A clear, Conservative plan not only generating security, but also prosperity for our country.
I can’t remember any reports about an energy security policy, which he outlined in the last paragraph of my extract from his speech.
He also said we would have sufficient electricity to export to our neighbours. As I said earlier some of this energy will be in the form of hydrogen, which has been created by offshore electrolysers.
If we are exporting electricity and hydrogen to Europe, this is likely to have three effects.
- An improvement in Europe’s energy security.
- H2ercules will improve and decarbonise German industry, using UK hydrogen.
- The finances of UK plc will improve.
It looks like there would be winners all round.
Rishi Sunak had the cards and he played them very badly.
It is now up to Keir Starmer, Great British Energy and Jürgen Maier to play those cards to link the energy systems of the UK and Germany to ensure security and prosperity for Europe.
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.
