Highview Power Plans To Develop 2.5GWh LDES Project In Scotland
The title of this post is the same as that of this article on Power Technology.
This is the sub-heading.
The liquid air energy storage plant at Hunterston is set to deliver a substantial increase in storage capacity
These first three paragraphs add a few more details.
Highview Power has announced plans to develop a long-duration energy storage (LDES) project in Ayrshire, Scotland, with a capacity of 2.5 gigawatt hours (GWh).
The project will be built at Peel Ports’ property at Hunterston, North Ayrshire and will provide five times the existing battery storage capacity of Scotland.
It is supported by the Scottish government and its strategic location optimises the use of renewable electricity produced in the country.
Note.
- Highview Power talks of 200MW/2.5GWh capacity batteries in Scotland on its web site, so I suspect this battery is one of those.
- This battery is as large as some pumped storage hydro systems.
- In UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security, I described the funding now behind Highview Power. The funding appears to be solid, as it includes the UK Infrastructure Bank, Centrica, Goldman Sachs and Rio Tinto.
This is a good start for Highview Power.
1.4GW Of BESS Capacity Could Be Co-Located With AR6 Winners
The title of this post, is the same as that of this article on Solar Power Portal.
These are the first two introductory paragraphs of the article.
Analysis from Modo Energy has revealed that renewable energy projects awarded contracts under the Contracts for Difference (CfD) Allocation Round 6 (AR6) could facilitate 1.4GW of co-located battery energy storage systems (BESS).
While BESS projects themselves cannot directly participate in the CfD auction, projects awarded contracts are able to co-locate with a battery. Following changes to the rules following Allocation Round 4, BESS co-location is now a far easier prospect for generators, and AR6 saw record high levels of awards for solar projects.
Modo Energy have used two rules to decide which projects will have a battery.
Modo Energy analysis suggests that 5GW of the 9.6GW of renewable energy capacity awarded contracts in AR6 could be suitable for, or has already revealed plans for, co-located battery storage. As a result, as much as 1.4GW of BESS capacity could be created as part of new renewable projects resulting from the AR6.
Using an average ratio of 60MW of BESS capacity for every 100MW of solar generation capacity, Modo Energy has calculated that 1GW of this potential BESS capacity could come from solar projects alone.
Longfield Solar Energy Farm
The article and related documents also say this about Longfield Solar Energy farm.
- This could be the largest battery to co-locate with renewables from this allocation round.
- The project does have a web site.
- The farm has a 399 MW solar array.
- The web site says that the project will store or export up to 500 MW to and from the grid.
- The project is being developed by EDF Renewables.
- The solar farm appears to be North-East of Chelmsford.
The project should be completed by 2027/28.
Conclusion
As time goes on, we’lll see more and more batteries of all kinds co-located with renewable resources.
Out Of Thin Air: Solving The Dilemma Of Long-Duration Storage
The title of this post, is the same as that of this excellent article on the Australian Financial Review.
This is the sub-heading.
Two first-of-a-kind technologies in Australia are firming up as options to crack the tough nut of energy storage that lasts much longer than batteries.
This is the first paragraph.
Two competing technologies that use different forms of air to store energy are emerging as potential solutions for the thorny problem of long-duration storage needed to smooth out Australia’s bumpy transition to low-carbon energy.
The article then compares the two competing technologies.
- Hydrostor of Canada are developing the 200 MW/1600 MWh Silver City Energy Storage Centre at Broken Hill in New South Wales.
- Highview Power of the UK are proposing a 12-hour energy store for the Northern Territory.
Australia certainly has plenty of solar power to fill the energy storage.
Global Offshore Wind To Top 520 GW By 2040, Floating Wind To Play Major Role – Rystad Energy
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
According to Rystad Energy, global offshore wind capacity will surpass 520 GW by 2040, with floating wind installations nearing 90 GW by that time
These are the first three paragraphs.
In 2023, the offshore wind sector saw a seven per cent increase in new capacity additions compared to the previous year, said Rystad Energy. This momentum is expected to accelerate this year, with new capacity additions expected to grow by nine per cent to over 11 GW by the end of the year.
By 2040, Europe is expected to account for more than 70 per cent of global floating wind installations. Although some project delays beyond 2030 are anticipated, there will likely be a strong push to accelerate deployment, according to Rystad Energy.
As a result, floating wind capacity is projected to approach 90 GW by 2040, led by the UK, France, and Portugal, with Asia (excluding mainland China) expected to account for 20 per cent of global installations.
Note, that Rystad Energy is an independent energy research and business intelligence company headquartered in Oslo, Norway.
Implications For Energy Storage
In Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, I talk about how the 2.9 GW Hornsea Three wind farm will have a connection to the grid, that incorporates a 300 MW/600 MWh battery.
With 520 GW of offshore wind to be installed by 2040, I suspect that energy storage companies and funds will do well.
If the 520 GW of offshore wind were fitted with batteries like the 2.9 GW Hornsea Three wind farm, there would be a need for around 60 GW of battery output, with a capacity of around 120 GWh.
I doubt, there would be enough lithium for all those batteries.
Some countries like Norway, the United States, Australia, France, Spain, Japan, India, China and others will be able to develop large pumped storage hydroelectricity systems, but others will have to rely on newer, developing technologies.
The UK will be well-placed with around 80 GWh of pumped storage hydroelectricity under development and several promising developing storage technologies.
Welcoming GB Energy And Its Mission To Make Britain A Clean Energy Superpower
The title of this post, is the same as that of this press release from SSE.
This is the sub-heading.
Making Britain a clean energy superpower by 2030 is one of the new government’s five missions. The UK Government and Crown Estate have announced plans to join forces to create a new publicly owned energy firm. GB Energy will invest in homegrown, clean energy.
These are the first two paragraphs of SSE’s response to the announcement.
We welcome the focus of GB Energy on earlier stage technologies, such as carbon capture and storage (CCS), where the Government can de-risk projects and help accelerate the clean energy transition.
In areas such as offshore wind, where industry is already delivering mission-critical infrastructure, the biggest impact will be on delivering policies that speed up the build out of these essential projects.
It looks like SSE, see Great British Energy as a positive development.
SSE And Gilkes Energy Announce Joint Plans To Progress Loch Fearna Pumped Storage Hydro Project
The title of this post, is the same as that of this press release from SSE Renewables.
These five paragraphs from the press release outline the scheme.
SSE has announced plans to progress a new pumped storage hydropower scheme at Loch Fearna in Scotland’s Great Glen, in a 50:50 development joint venture with a consortium led by Gilkes Energy.
The proposed co-development is located at the western end of Glengarry around 25km west of Invergarry and adjoins SSE Renewables’ existing Loch Quoich reservoir in the Great Glen hydro scheme.
SSE Renewables already operates the largest fleet of hydro-electric power and pumped storage hydro assets in Scotland. It is now progressing development plans for new pumped storage hydropower projects in the Highlands to complement its existing fleet and deliver the large-scale, long-duration electricity storage (LDES) needed as part of Britain’s future energy mix.
The Fearna Pumped Storage Hydro (PSH) project envisages the development of tunnels and a new power station connecting SSE Renewables’ existing reservoir at Loch Quoich with an upper reservoir at Loch Fearna.
Under the terms of the joint venture being announced today, Gilkes Energy will lead the project’s development under a development services agreement with SSE Renewables.
I wrote about the Great Glen hydro scheme in Repurposing The Great Glen Hydro-Electric Scheme, where I included this map, from the SSE Renewables web site shows the layout of the dams and power stations.
The sizes of the power stations in the scheme are as follows.
- Ceannacroc – 20 MW
- Livishie – 15 MW
- Glenmoriston- 37 MW
- Quoich – 18 MW
- Invergarry – 20 MW
- Mucomir – 1.7 MW
This gives a total power of 112.7 MW.
This five paragraph from the press release details the size of the scheme.
It is envisaged the proposed development would be up to 1.8GW in generating capacity and capable of producing around 37GWh of stored energy capacity. The project has already secured a grid connection offer totalling 1,795MW.
The 1.8 GW/37 GWh Fearna pumped hydro scheme will dwarf the Great Glen hydro scheme.
it is now seventy years since some of these hydro-electric systems were built in Scotland.
As an engineer, I wouldn’t be surprised to a see a fair amount of updating in the Highlands to upgrade Scotland’s hydro-electricity.
ILI Group Progresses Plans For 1.5GW Pumped Storage Hydro Project
The title of this post, is the same as that of this article on Power Technology.
This is the sub-heading.
The company has submitted a Section 36 planning application to the Scottish government.
These three paragraphs give more details.
The Intelligent Land Investments (ILI) Group has submitted a Section 36 planning application to the Scottish government for its 1.5GW Balliemeanoch pumped storage hydro project in Argyll and Bute.
The initiative will boost the UK’s renewable energy capacity and supply electricity to 4.5 million homes.
With an anticipated connection date of 2031, the project is strategically aligned with the UK’s long-term energy strategy.
Note.
- It will have a storage capacity of 45 GWh.
- It will be by far, the largest pumped storage hydroelectric power station in the UK. The under development Coire Glas pumped storage system is 24 GWh.
When the UK or Europe needs more power after completion of Balliemeanoch and Coire Glas, the Highlands of Scotland will provide the power.
Gresham House Energy Storage Reaches 1 Gigawatt Of Capacity
The title of this post, announcing a major milestone for Gresham House Energy Storage Fund appears on several web pages.
Many grid batteries are designed to give full power for two hours, so applying that rule to the Gresham House Energy Storage fleet, will mean that the total fleet would be a 1 GW/2 GWh battery.
Consider.
- In Centrica Business Solutions And Highview Power, I showed how Highview Power’s batteries could be used, instead of lithium-ion batteries.
- Highview Power’s largest battery is 200 MW/2.5 GWh, which compares well with the largest lithium-ion batteries, in the UK fleet.
- The Ffestiniog Power Station is a 360 MW/1.44 GWh pumped-storage hydroelectric power station in Wales. It is slightly smaller than Highview Power’s largest battery.
- Moss Landing Power Plant in California is proposing to have a 1,500 MW / 6,000 MWh lithium-ion battery.
- Other GWh-scale systems are under trial.
It would appear that battery systems are widening the sizes of where they can be employed.
This hopefully, will mean more competition and keener prices for battery systems.
Wood To Optimise Hydrogen Storage For Centrica’s Rough Field
The title of this post, is the same as that of this press release from Wood plc.
These are the first three paragraphs.
Wood, a global leader in consulting and engineering, has been awarded a contract by Centrica Energy Storage (CES) for the redevelopment of the UK’s Rough field in readiness for future hydrogen storage.
The Rough reservoir, located in the Southern North Sea, has been used to store natural gas safely for over thirty years and has the potential to provide over half of the UK’s hydrogen storage requirements.
The front-end engineering design (FEED) contract, awarded to Wood, entails new pipelines, a new unmanned installation, as well as onshore injection facilities at the Easington Gas Terminal, is the first step in making the field hydrogen ready.
Offshore Magazine has this article about the deal, which is entitled Wood Assessing Hydrogen Storage Needs For North Sea Rough Reservoir.
This is a paragraph from the Offshore Magazine article.
Centrica aims to position the Rough Field as the world’s largest long-duration hydrogen storage facility, although FID on the redevelopment project would depend on government support.
It would be a very important project.
Why would Centrica be planning for this massive increase in hydrogen storage?
There could only be one reason.
There is going to be a massive increase in hydrogen production and use.
In Where’s The Plan, Rishi?, I laid out what I believe will happen in the next few years.
- In RWE Goes For An Additional 10 GW Of Offshore Wind In UK Waters In 2030, I detailed how RWE intended to add an extra 10 GW of offshore wind to the seas around the UK.
- As our current offshore wind capacity is around 15 GW, so another 10 GW would surely be very welcome.
- The Germans will develop H2ercules, which is their massive project to create a hydrogen network to bring hydrogen to Southern Germany.
- A hydrogen hub at Wilhelmshaven is being built by Uniper to feed H2ercules with green hydrogen from around the world.
But would it not be better, if instead of feeding H2ercules with hydrogen from around the world, some came from the UK, a few hundred miles across the North Sea?
- RWE are developing the 3 GW Dogger Bank South wind farm, which is not in the best place for a cable to the UK. So could this wind farm have an offshore electrolyser and send the hydrogen to Wilhelmshaven, by pipeline or coastal tanker?
- RWE are also developing the 4.2 GW Norfolk cluster of wind farms to the North-East of Great Yarmouth. It might be better, if the output of these wind farms took a hydrogen route to Wilhelmshaven.
- I also believe that a third offshore electrolyser might be situated North of the Wash to bring more hydrogen to Germany.
- Hydrogen could also be sent from the Rough facility to Wilhelmshaven.
The coastal tanker route gives flexibility, so green hydrogen could be sent as required to the UK mainland.
Rishi Sunak’s Manifesto Speech – June 11
I also 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.
It is now nineteen days since Rishi made that speech and 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 particularly mentioned.
- New gas-powered stations
- Trebling our offshore wind capacity
- Having new fleets of small modular reactors.
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 will be winners all round.
Conclusion
Centrica’s plan for a massive hydrogen store at Rough, close to SSE’s existing gas storage in the salt caverns at Aldbrough, would appear to make sense, if the UK’s excess of offshore wind is converted into green hydrogen, which is then stored and distributed as needed.
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.
