Where’s The Plan, Rishi?
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, another 10 GW would surely be very welcome.
My post also outlined H2ercules, which is Germany’s massive project to create a hydrogen network to bring hydrogen to Southern Germany.
I also gave details of the hydrogen hub at Wilhelmshaven, which is being built by Uniper to feed H2ercules with green hydrogen from around the world.
I believe that some of this hydrogen for H2ercules will take a short trip across the North Sea from UK waters, after being created by offshore electrolysers.
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 nine 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.
Rishi also said this, in his speech.
As Putin’s invasion of Ukraine has shown, we need energy security too.
The gas-powered stations, offshore wind farms and the fleets of small modular reactors, will be part of the equation.
But I believe, we need three other components to complete our energy security.
- The upgrading of the National Grid.
- The building of four x 2 GW interconnectors between Scotland and Eastern England.
- Large amounts of energy storage.
Note.
- The Great Grid Upgrade and the four x 2 GW interconnectors are being planned.
- In Huge Boost To UK Supply Chain As National Grid Launches The Great Grid Partnership With Seven New Industry Partners, All United In The Drive To Deliver The Great Grid Upgrade, I describe how National Grid has setup the Great Grid Partnership to deliver the Great Grid Upgrade.
- In UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security, I describe how the big boys do a deal with Highview Power to create affordable batteries for the UK and the world.
- In Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, I describe how the very large Swardeston BESS is to be built near Norwich.
- In Mercia Power Response & RheEnergise Working Together To Build Long Duration Energy Storage Projects In The UK, I describe another UK-developed long duration energy storage system, which is now being planned.
- In National Grid Shares Proposals For Green Electricity Projects In Lincolnshire And West Norfolk, Needed To Boost Home-Grown Energy Supplies And Progress Towards Net Zero, I describe National Grid’s projects in the East of England.
- In UK ESO Unveils GBP 58 Billion Grid Investment Plan To Reach 86 GW of Offshore Wind By 2035, I show how we’re not that far away from 86 GW by 2035.
- In 400k For National Grid Innovation Projects As Part Of Ofgem Fund To Help Shape Britain’s Net Zero Transition, I describe how National Grid is using innovation to help target net-zero by 2035.
- In Iberdrola Preparing Two East Anglia Offshore Wind Projects For UK’s Sixth CfD Round, I describe how Iberdrola is getting 1.7 GW ready for commissioning in 2026.
- In National Grid To Accelerate Up To 20GW Of Grid Connections Across Its Transmission And Distribution Networks, I describe how National Grid are accelerating the development of the electricity networks. 10 GW of battery storage is a collateral benefit.
These ten projects, most of which are financed and/or underway, would appear to be good foundations, on which to build the Great Grid Upgrade.
It looks to me, that National Grid, RWE, Centrica, Iberdrola and others, by just doing what comes naturally have offered the next government a road to a future.
It will be interesting, what gets said before the election.
UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security
The title of this post, is the same as that of this news item from Highview Power.
This is the sub-heading.
Highview Power kickstarts its multi-billion pound renewable energy programme to accelerate the UK’s transition to net zero in Carrington, Manchester.
These three paragraphs outline the investment.
Highview Power has secured the backing of the UK Infrastructure Bank and the energy industry leader Centrica with a £300 million investment for the first commercial-scale liquid air energy storage (LAES) plant in the UK.
The £300 million funding round was led by the UK Infrastructure Bank (UKIB) and the British multinational energy and services company Centrica, alongside a syndicate of investors including Rio Tinto, Goldman Sachs, KIRKBI and Mosaic Capital.
The investment will enable the construction of one of the world’s largest long duration energy storage (LDES) facilities in Carrington, Manchester, using Highview Power’s proprietary LAES technology. Once complete, it will have a storage capacity of 300 MWh and an output power of 50 MWs per hour for six hours. Construction will begin on the site immediately, with the facility operational in early 2026, supporting over 700 jobs in construction and the supply chain.
Note.
- The backers are of a high quality.
- The Carrington LDES appears to be a 50 MW/300 MWh battery.
It finally looks like Highview Power is on its way.
These are my thoughts on the rest of news item.
Centrica’s Involvement
This paragraph talks about Centrica’s involvement.
Energy leader Centrica comes on board as Highview Power’s strategic partner and a key player in the UK’s energy transition, supporting Carrington and the accelerated roll-out of the technology in the UK through a £70 million investment. The programme will set the bar for storage energy systems around the world, positioning the UK as the global leader in energy storage and flexibility.
I suspect that Centrica have an application in mind.
In Centrica Business Solutions Begins Work On 20MW Hydrogen-Ready Peaker In Redditch, I talk about how Centrica is updating an old peaker plant.
In the related post I refer to this news item from Centrica Business Systems.
This paragraph in the Centrica Business Systems news item, outlines Centrica’s plans.
The Redditch peaking plant is part of Centrica’s plans to deliver around 1GW of flexible energy assets, that includes the redevelopment of several legacy-owned power stations, including the transformation of the former Brigg Power Station in Lincolnshire into a battery storage asset and the first plant in the UK to be part fuelled by hydrogen.
As Redditch power station is only 20 MW, Centrica could be thinking of around fifty assets of a similar size.
It seems to me, that some of these assets could be Highview Power’s LDES batteries of an appropriate size. They may even be paired with a wind or solar farm.
Larger Systems
Highview Power’s news item, also has this paragraph.
Highview Power will now also commence planning on the next four larger scale 2.5 GWh facilities (with a total anticipated investment of £3 billion). Located at strategic sites across the UK, these will ensure a fast roll-out of the technology to align with UK LDES support mechanisms and enable the ESO’s Future Energy Scenario Plans.
Elsewhere on their web site, Highview Power say this about their 2.5 GWh facilities.
Highview Power’s next projects will be located in Scotland and the North East and each will be 200MW/2.5GWh capacity. 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.
So will the four larger systems have a 200MW/2.5GWh capacity?
They could, but 200 MW may not be an appropriate output for the location. Or a longer duration may be needed.
Highview Power’s design gives the flexibility to design a system, that meets each application.
Working With National Grid
Highview Power’s news item, also has this sentence.
Highview Power’s technology will also provide stability services to the National Grid, which will allow for the long-term replacement of fossil fuel-based power plants for system support.
Highview Power’s technology is also an alternative to Battery Energy Storage Systems (BESS) of a similar capacity.
How does Highview Power’s technology compare with the best lithium-ion systems on price, performance and reliability?
Curtailment Of Wind Farms
Highview Power’s news item, also has these two paragraphs.
This storage will help reduce curtailment costs – which is significant as Britain spent £800m in 2023 to turn off wind farms.
Highview Power aims to accelerate the roll-out of its larger facilities across the UK by 2035 in line with one of National Grid’s target scenario forecasts of a 2 GW requirement from LAES, which would represent nearly 20% of the UK’s long duration energy storage needs. By capturing and storing excess renewable energy, which is now the cheapest form of electricity, storage can help keep energy costs from spiralling, and power Britain’s homes with 24/7 renewable clean energy.
I can see several wind farms, that are regularly curtailed would have a Highview Power battery installed at their onshore substation.
Receently, I wrote Grid Powers Up With One Of Europe’s Biggest Battery Storage Sites, which described how Ørsted are installing a 300 MW/600 MWh Battery Energy Storage Systems (BESS) at Swardeston substation, where Hornsea Three connects to the grid.
I would suspect that the purpose of the battery is to avoid turning off the wind farm.
Would a Highview Power battery be better value?
What’s In It For Rio Tinto?
I can understand, why most companies are investing, but Rio Tinto are a mining company. My only thought is that they have a lot of redundant holes in the ground, that cost them a lot of money and by the use of Highview Power’s technology, they can be turned into productive assets.
Collateral Benefits
Highview Power’s news item, also has this paragraph.
Beyond contributing to the UK’s energy security by reducing the intermittency of renewables, Highview Power’s infrastructure programme will make a major contribution to the UK economy, requiring in excess of £9 billion investment in energy storage infrastructure over the next 10 years – with the potential to support over 6,000 jobs and generate billions of pounds in value add to the economy. It will also contribute materially to increasing utilisation of green energy generation, reducing energy bills for consumers and providing significantly improved energy stability and security.
If Highview Power can do that for the UK, what can it do for other countries?
No wonder companies of the quality of Centrica, Rio Tinto and Goldman Sachs are investing.
Highview Power, Ørsted Find Value In Integrating Offshore Wind With Liquid Air Energy Storage
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Highview Power and Ørsted have completed their joint investigation into how combining the technologies of Liquid Air Energy Storage (LAES) and offshore wind could unlock greater value for investors and consumers.
These three paragraphs outline the findings.
The results show that there is value in combining offshore wind with LAES to support reducing wind curtailment, increasing productivity, and helping the move to a more flexible, resilient zero-carbon grid, according to Higher Power.
The two companies have carried out analysis of technical performance, route to planning approval, and route to market with a regulatory and economic assessment.
As a result of this study, the companies believe a project can be developed and built aligned with the timeline of an offshore wind farm.
I feel very strongly, that putting the two technologies together is a good idea.
In the simplest cases, the storage could be built into the offshore sub-station.
Could LAES Be Used With Hornsea 4 Wind Farm?
The Wikipedia entry for the Hornsea Wind Farm says this about Hornsea 4.
In July 2023, British government officials gave the final approval for Hornsea Four, the fourth phase of the wind project. Hornsea Four is expected to generate 2.6GW, have 180 giant wind turbines, and has the capability to generate enough renewable energy to power 1 million homes in Britain.
The Wikipedia entry also says this about Hornsea 3.
Project 3 will be to the east of Projects 1 and 2, with an estimated maximum capacity of 2.4 GW over 696 square kilometres (269 sq mi). DONG Energy (which in November 2017 changed its name to Ørsted) began consultation on the project’s development in May 2016. Ørsted submitted a Development consent application in 2018 and consent was granted on 31 December 2020.[69] In early 2023, consent was also given to a battery storage power station at Swardeston. The project is expected to begin construction in 2022, and be completed by 2025.
If Ørsted are adding a battery to the 2.4 GW Hornsea 3 wind farm, I would feel, that Ørsted would think about a battery on the 2.6 GW Hornsea 4 wind farm.
The Energy Storage The UK Needs
This is the last paragraph of the article.
The UK will need up to 100 GWh of energy storage by 2050 according to the estimates from National Grid ESO’s Future Energy Systems Scenario.
SSE Renewables are planning two large pumped-storage hydroelectric power stations in Scotland.
- Coire Glas – 1.5 GW/30 GWh – Possible completion in 2031.
- Loch Sloy – 152.5 MW/25 GWh – See SSE Unveils Redevelopment Plans For Sloy Hydro-Electric Power Station.
A quick calculation, says we’d need seven pumped-storage hydroelectric power stations, which need a lot of space and a handy mountain.
I don’t think pumped-storage hydroelectric would be feasible.
Highview Power say this about their next projects on this page of their web site.
Highview Power’s next projects will be located in Scotland and the North East and each will be 200MW/2.5GWh capacity. 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.
Note.
- This is more like the size.
- Work is now underway at Carrington – a 50MW / 300MWh plant at Trafford Energy Park near Manchester.
- Highview’s technology uses liquid air to store energy and well-proven turbo-machinery.
They are a definite possibility, as only eighteen 200MW/2.5GWh systems would be needed.
National Grid To Accelerate Up To 20GW Of Grid Connections Across Its Transmission And Distribution Networks
The title of this post, is the same as that of this press release from National Grid.
These four bullet points, act as sub-headings.
- Connection dates of 10GW of battery projects accelerated at transmission level, and 10GW of capacity unlocked at distribution level, both part of the Electricity System Operator (ESO)’s connections five-point plan.
- Battery energy storage projects connecting to the transmission network to be offered new connection dates averaging four years earlier than their current agreement.
- The accelerated 20GW equates to the capacity of six Hinkley Point C nuclear power stations.
- Work is part of ongoing collaborative industry efforts, together with Ofgem and government, to speed up and reform connections.
This is the opening paragraph.
National Grid is accelerating the connection of up to 20GW of clean energy projects to its electricity transmission and distribution networks in England and Wales as part of ongoing collaborative work across industry.
As I write this, the UK is generating 38.5 GW of electricity, so another 20 GW will be a large increase in capacity.
I shall look at what National Grid are proposing in sections.
10 GW Of Battery Power
These two paragraphs, outline the plan for 10 GW of battery power.
On its transmission network, 19 battery energy storage projects worth around 10GW will be offered dates to plug in averaging four years earlier than their current agreement, based on a new approach which removes the need for non-essential engineering works prior to connecting storage.
The new policy is part of National Grid’s connections reform initiative targeting transmission capacity, spearheaded by the ESO – which owns the contractual relationship with connecting projects – and actioned jointly with National Grid Electricity Transmission (ET), the part of the business which designs and builds the transmission infrastructure needed in England and Wales to plug projects in.
It looks to me that someone has been doing some serious mathematical modelling of the UK’s electricity network.
Fifty years ago, I provided the differential equation solving software, that enabled the Water Resources Board to plan, where reservoirs and pipelines were to be built. I have no idea how successful it was, but we don’t seem to have any serious water supply problems, except when there is equipment failures or serious drought.
But modelling water and electrical networks is mathematically similar, with rainfall, pipelines and reservoirs in the water network and power generation, transmission lines and batteries and pumped storage hydroelectricity in the electricity network.
I’d be interesting to know what software was used to solve the mathematical model.
I certainly agree with the solution.
Two of our modern sources of renewable energy; solar and wind are not very predictable, but cost a lot of capital investment to build.
So it is very wrong not to do something positive with any excess electricity generated. And what better place to put it than in a battery, so it can be retrieved later.
The earlier, the batteries come on stream, the earlier, the batteries can save all the excess electricity.
So moving the plug in dates for battery storage four years earlier is a very positive thing to do.
A simple calculation shows that for 10 GW, we would need nineteen batteries of about 526 MW.
Ideally, like power stations, they would be spread around the country.
Could Pumped-Storage Hydroelectricity Be Used?
The largest battery in the UK is the Dinorwig pumped-storage hydroelectric power station, which is commonly known as Electric Mountain or Mynydd Gwefru if you’re Welsh.
- It opened in 1984, after a ten years of construction.
- It has a power output of 1.8 GW.
- The energy storage capacity of the station is around 9.1 GWh.
Roughly, every gigawatt of output is backed up by 5 GWh of storage.
If the proposed nineteen new batteries have the same power to storage ratio as Electric Mountain, then each battery will have a storage capacity of 2.63 GWh
SSE Renewables are planning two large pumped-storage hydroelectric power stations in Scotland.
- Coire Glas – 1.5 GW/30 GWh – Possible completion in 2031.
- Loch Sloy – 152.5 MW/25 GWh – See SSE Unveils Redevelopment Plans For Sloy Hydro-Electric Power Station.
A quick calculation, says we’d need seven pumped-storage hydroelectric power stations, which need a lot of space and a handy mountain.
I don’t think pumped-storage hydroelectric would be feasible.
Could Lithium-Ion Batteries Be Used?
My mathematical jottings have shown we need nineteen batteries with this specification.
- An output of about 526 MW.
- A storage capacity of around 2.63 GWh
This Wikipedia entry gives a list of the world’s largest battery power stations.
The current largest is Vistra Moss Landing battery in California, which has this specification.
- An output of 750 MW.
- A storage capacity of 3 GWh
Reading the Wikipedia entry for Vistra Moss Landing, it appears to have taken five years to construct.
I believe that nineteen lithium-ion batteries could handle National Grid’s need and they could be built in a reasonable time.
Could Any Other Batteries Be Used?
Rounding the battery size, I feel it would be better have twenty batteries with this specification.
- An output of 500 MW.
- A storage capacity of 2.5 GWh
Are there any companies that could produce a battery of that size?
Form Energy
Form Energy are well-backed with an MIT heritage, but their largest proposed battery is only 10 MW/1 GWh.
They could be a possibility, but I feel it’s only a small chance.
Highview Power
Highview Power say this about their next projects on this page of their web site.
Highview Power’s next projects will be located in Scotland and the North East and each will be 200MW/2.5GWh capacity. 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.
Note.
- This is more like the size.
- Work is now underway at Carrington – a 50MW / 300MWh plant at Trafford Energy Park near Manchester.
- Highview’s technology uses liquid air to store energy and well-proven turbo-machinery.
- Highview have a co-operation agreement with Ørsted
They are a definite possibility.
10 GW Of Extra Unlocked Capacity
These two paragraphs, outline the plan for 10 GW of extra unlocked capacity.
On its distribution network in the Midlands, South West of England and South Wales, the additional 10GW of unlocked capacity announced recently is set to accelerate the connection of scores of low carbon technology projects, bringing forward some ‘shovel ready’ schemes by up to five years.
National Grid has already been in contact with more than 200 projects interested in fast tracking their distribution connection dates in the first wave of the capacity release, with 16 expressing an interest in connecting in the next 12 months and another 180 looking to connect within two to five years.
This page from National Grid ESO, lists the actions that were taken to release the extra grid capacity.
Conclusion
This looks to be a very good plan from National Grid.
Carlton Power Secures Planning Consent For World’s Largest Battery Energy Storage Scheme
The title of this post, is the same as that of this news story from Carlton Power.
This is the sub-heading.
£750m 1GW Battery Project To Be Built At Carlton Power’s Trafford Low Carbon Energy Park In Greater Manchester
These three paragraphs outline the project.
Carlton Power, the UK independent energy infrastructure development company, has secured planning permission for the world’s largest battery energy storage scheme (BESS), a 1GW (1040MW / 2080MWh) project located at the Trafford Low Carbon Energy Park in Greater Manchester. The £750m BESS scheme will strengthen the security and resilience of the energy system in the North West of England, and support the energy transition and the growth of renewable power generation in the region.
Planning permission for the BESS was granted by Trafford Council, the local planning authority.
Subject to a final investment decision, construction of the battery storage scheme is expected to begin in the first quarter of next year (2024) with it entering commercial operation in the final quarter of 2025. Carlton Power is in advanced talks with companies to finance, build and operate the Trafford BESS.
I have a few thoughts.
It’s A Monster
This Wikipedia entry, lists the World’s Largest Grid Batteries.
- The current largest is Vistra Moss Landing battery in the United States, which has a capacity of 1600 MWh and an output of 400 MW.
- The Trafford BESS will have a capacity of 2080 MWh and an output of 1040 MW.
By both measures the Trafford BESS is larger.
Where Will It Get The Energy?
Consider.
- In Liverpool and Morecambe Bays there is over 5 GW of offshore wind farms either operational, under construction or planned.
- Carrington gas-fired power station has a capacity of 884 MW.
- The Western HVDC Link is a 2250 MW link between Scotland and Connah’s Quay in North Wales.
- I wrote about the proposed Mersey Barrage in Mersey Tidal Project And Where It Is Up To Now.
I can see enough renewable energy being generated to replace Carrington gas-fired power station.
Who Will Finance, Build And Operate The Trafford BESS?
There are two major Energy Storage Funds in the UK.
- Gore Street with 27 projects totalling 1.17 GW.
- Gresham House with 17 projects totalling 425 MW.
Note.
- There are other smaller funds.
- The figures given are cumulative outputs for the portfolios.
- Sourcing the large number of batteries might be a problem.
- As the maths of these batteries are now well-known, I would expect that finance shouldn’t be too much of a problem.
- Local companies like Liverpool Victoria or Peel Holdings could even take a position.
A large American contractor backed by US money could swallow the whole project.
That happened with North Sea oil and gas in the last century.
Is Highview Power’s CRYOBattery Still Planned?
Carlton Power’s news story says this about Highview Power’s plans.
In addition to Carlton Power’s two projects, Highview Power Storage Inc. is planning to build and operate the world’s first commercial liquid air storage system – a £250m 250MWh long duration, cryogenic energy storage system – on the Trafford Low Carbon Energy Park, which was until 1991 the site of the Carrington coal-fired power station. The Low Carbon Energy Park is located close to Manchester Ship Canal and the £750m Carrington flexible gas-fired power station which entered operation in 2016.
It seems that the CRYOBattery is still planned.
Conclusion
Manchester is getting a powerful zero-carbon hub.
Japanese Companies To Invest GBP 14.2 Billion In UK’s Offshore Wind, Green Hydrogen
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Japanese giants Marubeni Corporation, Sumitomo Corporation, and Sumitomo Electric Industries have committed to investing a total of GBP 14.2 billion (approximately EUR 16.3 billion) in offshore wind and green hydrogen projects, and the offshore wind supply chain in the UK
These two paragraphs add a bit of context and flesh to the deal.
Ahead of the UK Prime Minister’s business reception in Tokyo on 18 May, the UK government announced that leading Japanese businesses have committed to invest GBP 17.7 billion (approx. EUR 20.3 billion) in businesses and projects across the UK.
Of this, GBP 14.2 billion has been committed by Marubeni, Sumitomo and Sumitomo Electric for projects in offshore wind, green hydrogen and offshore wind supply chain.
SSE’s Berwick Bank Wind Farm will have a capacity of 4.1 GW and is budgeted to cost just short of £18 billion. Doing a quick calculation, indicates that £14.2 billion would only finance £3.23 GW of offshore wind.
But the Japanese say they will invest in offshore wind, green hydrogen and offshore wind supply chain. Investing in the offshore wind supply chain, would surely attract more money as the developers placed orders for foundations, floaters, electrical gubbins and support vessels.
Note.
- In Japanese Giant Sumitomo Heavy Invests In Liquid-Air Energy Storage Pioneer, I wrote about Sumitomo’s investment in English energy storage. company; Highview Power.
- Electrolyser company; iTM Power has also sold a 1.4 MW electrolyser to Sumitomo and signed an agreement over American sales with another Japanese company.
I can see other similar co-operative deals being developed. Possible areas could be cables, transformers and support vessels.
Gresham House Energy Storage Sets GBP80 Million Fundraise
Gresham House Energy Storage Fund must be doing something right, as similar headlines are used in half-a-dozen places on the Internet and they regularly seem to be raising more money.
But then, as a Graduate Control Engineer and a previous owner of half a finance company, I’ve always thought raising money to build batteries was a good idea.
My only niggle with Gresham House, is that I would have thought by now, they would have put some money into building one of the excellent new technology batteries that are coming through.
The storage fund or some of its employees, may of course have contributed to some of the crowdfunding for these new technologies, all of which I feel have a good chance of being a success.
Note.
- Energy Dome is Italian and all the others are at least fifty percent British.
- Most of the British batteries have had backing from the UK government.
- All these batteries are environmentally-friendly.
- None of these batteries use large quantities of rare and expensive materials.
- Energy Dome even uses carbon dioxide as the energy storage medium.
In addition, in Scotland, there is traditional pumped storage hydro-electricity.
Project Iliad
This article on renews.biz has a slightly different headline of Gresham House To Raise £80m For US Battery Buildout.
This is the first two paragraphs.
Gresham House Energy Storage Fund is seeking to raise £80m through a share placing.
The new equity raised will primarily be used to finance 160MW of solar with co-located four-hour battery projects in California, US, known as Project Iliad.
The article then gives a lot of financial details of Project Iliad and Gresham House.
Will Gresham House be backing co-located solar/battery projects in the UK?
- In Cleve Hill Solar Park, I write about a co-located solar/battery project in Kent.
- This press release from National Grid is entitled UK’s First Transmission-Connected Solar Farm Goes Live, which also describes a co-located solar/battery project, being built near Bristol.
These two projects are certainly serious and could be pathfinders for a whole host of co-located solar/battery projects.
WillGresham House back some of this new generation?
Boralex Commissions BESS At Wind Farm In France In EU-Supported Demonstration Project
The title of this post, is the same as that of this article on Energy Storage News.
These two paragraphs outline the project.
Canada-based renewable energy firm Boralex has turned on a 3.3MWh battery storage unit attached to a wind farm in France.
The battery storage project has been installed at the site of the Plouguin wind farm, an 8MW generating facility in the Finistere department of Brittany, northwest France.
Note.
- The project was co-financed by the European Union through its European Regional Development Fund (ERDF).
- The project was launched to demonstrate the technical feasibility of a hybrid wind-plus-storage project.
- Boralex added in its announcement that the project will contribute to the stability of the French electricity grid.
There will be a lot of projects like this in the future.
This paragraph makes an interesting point about using batteries with solar and wind power.
Wind farms are less frequently hybridised with energy storage than solar PV because of the larger minimum project size and less predictable variability, with sharper peaks meaning heavier battery cycling and potentially faster degradation.
My control engineering knowledge and experience says that larger power sources and those that are highly variable will need batteries with more capacity for the same stability and quality of power output.
This sounds to me like a very good reason for developing larger and more affordable batteries, like those of Cheesecake Energy, Energy Dome, Gravitricity and Highview Power.
It also probably means that to stabilise several gigawatts of wind power, you need a very large amount of storage, that can only be provided by pumped storage hydroelectricity.
Conclusion
A very large amount energy storage is going to be needed.
Projects like these are essential to make sure we use them to their full possibilities.
Highview Power And Ørsted Collaborate To Unlock Greater Value From The Next Generation Of Wind Farms
The title of this post, is the same as that of this press release from Ørsted.
This is the sub-heading.
Highview Power and Ørsted have signed a Memorandum of Understanding aiming to prove the feasibility and economic value of co-locating long duration energy storage with offshore wind.
This first paragraph indicates how the two companies will work together.
The two companies will carry out detailed technical analysis and an economic assessment during 2023 that will investigate how combining Ørsted’s wind technology with Highview Power’s liquid air energy storage can deliver a stronger investment case for future offshore wind projects by reducing wind curtailment, increasing productivity, and helping the move to a more flexible, resilient zero carbon grid.
This all good stuff and as a Control Engineer, I know, there is a very good chance, it will bring forward worthwhile benefits.
Diversifying A US$200 billion Market: The Alternatives To Li-ion Batteries For Grid-Scale Energy Storage
The title of this post, is the same as that of this article on Energy Storage News.
This is the introductory paragraph.
The global need for grid-scale energy storage will rise rapidly in the coming years as the transition away from fossil fuels accelerates. Energy storage can help meet the need for reliability and resilience on the grid, but lithium-ion is not the only option, writes Oliver Warren of climate and ESG-focused investment bank and advisory group DAI Magister.
Oliver starts by saying we need to ramp up capacity.
According to the International Energy Agency (IEA), to decarbonise electricity globally the world’s energy storage capacity must increase by a factor of 40x+ by 2030, reaching a total of 700 GW, or around 25% of global electricity usage (23,000TWh per annum). For comparison, this would be like swelling the size of the UK’s land to that of the USA.
Similar to how “nobody ever gets fired for buying IBM”, lithium-ion holds a similar place in grid scale electrical storage today.
And just as IBM did in the last decades of the last century, the builders of lithium-ion will fight back.
He then lists the problems of grid-scale lithium-ion batteries.
- Shortage of cobalt.
- Toxic and polluting extraction of some much needed metals and rare earths from unstable countries.
- Lack of capacity to load follow.
- Limited lifespan.
He does suggest vehicle-to-grid can provide 7TWh of storage by 2030, but it has similar problems to lithium-ion grid scale batteries.
Finally, he covers these what he considers several viable methods of energy storage in detail.
He introduces them with this paragraph.
No single killer application or technology exists to get the job done. Diversification is key with success dependent on the wide-scale adoption of multiple grid-scale energy storage solutions.
- Energy Dome – Italy – Stylish Use of CO2
- Augwind Energy – Israel – Stores Energy As Compressed Air Underground
- Cheesecake Energy – UK – Stores Energy As Heat And Compressed Air
- Highview Power – UK – Stores Energy As Liquefied Air
- Ocean Grazer – Netherlands – Ocean Battery
- RheEnergise – UK – High Density Hydro
- Lumenion – Germany/Japan – Stores Energy As Heat
- Energy Vault – Switzerland – Raising And Lowering Of Weights
Note.
- All systems are environmentally-friendly and use readily-available materials like air, water, sea-water, steel and concrete for their systems.
- The most exotic materials used are probably in the control computers.
- Some systems use readily-available proven turbo-machinery.
- Most systems appear to be scalable.
- All systems would appear to have a working life measured in decades.
- I would expect that most well-educated teenagers could understand how these systems worked.
Only Augwind Energy and Lumenion are new to me.
He finally sums up the economics and the market potential.
Our ability to expand energy storage capacity is one of the most pressing issues that will determine whether this defining ‘transitional’ decade is a success. But we’ll need to invest wisely into the right technologies that get the greatest bang for the buck (in terms of GWh capacity and return on capital) given the limited lifespan of Li-Ion and the decarbonisation of the grid.
At a current capital cost of US$2,000 per kW quoted by the US National Renewable Energy Laboratory (NREL) for 6-hour Li-ion battery storage, the 700GW of capacity needed by 2030 equates to around a US$1.5 trillion market over the coming decade, making it worth nearly US$200 billion a year.
The Energy Storage News article is a comprehensive must read for anyone, who is considering purchasing or investing in energy storage.
I have some further thoughts.
From My Experience Would I Add Any Other Systems?
I would add the following.
- Form Energy, because its iron-air battery is well-backed financially.
- Gravitricity, because it can use disused mine shafts to store energy and the world has lots of those.
- STORE Consortium, because its 3D-printed concrete hemispheres, that store energy using pressurised sea-water can be placed within a wind farm.
I also suspect that someone will come up with an energy storage system based on tidal range.
Finance
When we started Metier Management Systems, finance to breakout from the first initial sales was a problem. We solved the problem with good financial planning and an innovative bank manager who believed us all the way.
David, was a rogue, but he was a rogue on the side of the angels. Long after Metier, he even came to my fiftieth birthday party.
David would have found a way to fund any of these systems, as they tick all the boxes of demonstrated, environmentally-friendly, safe and understandable. They are also likely to be bought by companies, governments and organisations with a high net value, a very respectable reputation and/or large amounts of money.
I also think, that just as we did with the original Artemis project management system, some of these systems can be leased to the operators.
Second-Use Of Systems
Several of these systems could be moved on to a new location, if say they were supporting an industry that failed.
That would surely help the financing of systems.
