First Ever Gravity Green Energy Storage System Set For North Yorkshire Town
The title of this post, is the same as that of this article on the Yorkshire Post.
These paragraphs give an outline of the project.
Plans to create the UK’s first below ground gravity energy storage system have been unveiled in North Yorkshire.
Scottish energy storage firm Gravitricity is to apply to Ryedale District Council with its plan for a facility at East Knapton in Ryedale on the site of the former Knapton gas generator.
If completed, it could store up to four megawatt hours (4MWhs) of electricity – sufficient to power more than 9,000 homes for an hour.
It looks like the system will have an output of 4 MW.
This Google Map shows the two villages of West and East Knapton.
Note.
- The A64 road between Malton and Scarborough going across the map.
- Scarborough and the coast is about fifteen miles to the East.
- The Third Energy site in the North-East corner of the map.
This second Google Map shows the Third Energy site in more detail.
Note.
- The substation and a power line in the North-East corner of the map.
- The 42 MW Knapton Generating Station used to be on this site and it was powered by local gas wells.
Third Energy have now called the site Knapton Energy Park and it now has a web page, which has this mission statement.
Third Energy is developing the former Knapton Generating Station into the Knapton Energy Park. The energy park will house multiple sources of power generation and energy storage. The aim of the project is to pay a part in the development and generation of renewable energy systems in North Yorkshire, and contribute to making the UK Net Zero by 2050.
This paragraph talks about weights.
One of our technology partners has also received government funding to conduct feasibility studies for a pilot project at Knapton which would utilise suspended weights to store energy as an alternative to the traditional battery storage technologies. This project will be developed through 2022 onwards.
It looks like Gravitricity has planted an acorn in Yorkshire.
The Third Energy web site is worth an explore. This is the mission statement on the home page.
At Third Energy our aim is to be at the forefront of North Yorkshire’s transition from fossil fuels to sustainable energy. Our team are proactively playing a part in innovative energy solutions and energy development; transforming our facilities into a multi-purpose energy park and research centre.
I particularly like this page, which is entitled Plug & Abandon.
This is the outline of their P % A philosophy on the page.
As wells near the end of their life cycle they must be decommissioned and the land returned to its original state. Unfortunately, the current P&A practices of the oil and gas industry are cost prohibitive, resulting in delays to abandonment (as companies attempt to avoid the high cost), and poor abandonment practices that may be harmful to the environment.
Fortunately, there are solutions to this problem. Our ambition is to use new and innovative technologies to P&A the wells in a more effective and sustainable manner, and first to extend the period our wells may service the community by re-purposing them for geothermal energy.
Can they really convert abandoned gas wells into geothermal energy sources?
ILI Group Secures Planning Consent For 50MW Energy Storage Project
The title of this post, is the same as that of this article on Solar Power Portal.
ILI Group or Intelligent Land Investments Group to give them their full name, are a Scottish-based company, that I follow as I like their energy storage developments.
The home page of their web site, lists three main areas of activity.
The home page also has a scrolling mission statement of
- UK Energy Security
- 4GW of Energy Storage Projects
- Aligned with government policy
- Saving over 200million tonnes of CO2e
- Over £4 billion of Investment
It is very much worth reading the section of the ILI Group web site, which talks about pumped-storage hydroelectricity.
It starts with a overview of the Pump Storage Sector.
Between 2007 and 2015, the total installed capacity of renewables electricity in Scotland has more than doubled. Due to its intermittent nature, the rise in renewable generation has resulted in increased demand for flexible capacity to help meet energy balancing requirements for the national grid system.
Pumped storage hydro is considered by the Directors to be the most developed and largest capacity form of grid energy storage that currently exists. This can help reduce renewable energy curtailment and therefore promote grid stability.
It then gives an overview of how pumped-storage hydroelectricity works and the benefits of the technology.
The section finishes by noting that the company has secured planning permission for the Red John pumped-storage hydroelectric power station.
The article on the Solar Power Portal, also has this paragraph on ILI Group’s ambitions for pumped-storage hydroelectricity.
ILI Group is also responsible for the development of a 1.5GW pumped storage hydro project at Loch Awe. The Balliemeanoch project based at Dalmally in Argyll and Bute will be able to supply 1.5GW of power for up to 30 hours. It is the third and largest of ILI’s pumped storage hydro projects, with the other two being Red John at Loch Ness and Corrievarkie at Loch Ericht.
Note these points about the Balliemeanoch project.
- It has a storage capacity of 45 GWh, which is around the total amount of electricity, the whole of the UK would use in two hours.
- It couldn’t power the UK, as it has an output of only 1.5 GW and the UK needs at least 23 GW.
- The largest pumped storage hydroelectric power station in the UK is Dinorwig power station, which has an output of 1.8 GW and a storage capacity of 9.1 GWh.
In terms of storage capacity, the Balliemeanoch project will probably be the largest in the UK.
The section of the ILI Group web site, that talks about battery storage, opens with an overview of battery storage opportunities, where this is said.
Battery storage projects provide an enticing new opportunity for landowners and investors alike. As a market that will see significant growth over the coming years (National Grid predict up to 40GW of storage could be required by 2050) we see exciting new opportunities in a sector that will be critical to meeting our climate change needs.
Whereas our pumped storage hydro projects will provide long-term storage capacity, our batteries will provide short-term services (less than 4 hours) to the electricity system. As the system decarbonises, becoming steadily more reliant on intermittent green renewable generation, storage will play a role of increasing importance in balancing the grid and ensuring security of supply.
Note.
- This is a sales pitch to landowners and investors.
- National Grid’s prediction of 40GW of storage by 2050, could be able to store as much as 1200 GWh of electricity.
- I agree with their statement that there will be a need for both pumped storage hydro and batteries.
The section finishes with a status summary of 21 battery projects that they are developing.
Conclusion
I feel that ILI Group is a company that means business and knows where it’s going.
The UK probably needs several more companies like the ILI Group.
Significant Step Forward For Keadby 3 Carbon Capture Power Station
The title of this post, is the same as that of this press release from SSE.
These three paragraphs outline the project.
A landmark project in the Humber which could become the UK’s first power station equipped with carbon capture technology has taken a major leap forward following an announcement by the UK Government today.
Keadby 3 Carbon Capture Power Station, which is being jointly developed by SSE Thermal and Equinor, has been selected to be taken forward to the due diligence stage by the Department for Business, Energy and Industry Strategy (BEIS) as part of its Cluster Sequencing Process.
This process will give the project the opportunity to receive government support, allowing it to deploy cutting edge carbon capture technology, and to connect to the shared CO2 pipelines being developed through the East Coast Cluster, with its emissions safely stored under the Southern North Sea. The common infrastructure will also supply low-carbon hydrogen to potential users across the region.
The press release also says this about the power station.
- Keadby 3 power station could have a generating capacity of up to 910MW.
- It could be operational by 2027.
- It would capture up to one and a half million tonnes of CO2 a year.
It would provide low-carbon, flexible power to back-up renewable generation.
The H2H Saltend Project
The press release also says this about the H2H Saltend project.
Equinor’s H2H Saltend project, the ‘kick-starter’ for the wider Zero Carbon Humber ambition, has also been taken to the next stage of the process by BEIS. The planned hydrogen production facility could provide a hydrogen supply to Triton Power’s Saltend Power Station as well as other local industrial users. In June, SSE Thermal and Equinor entered into an agreement to acquire the Triton Power portfolio.
I wrote about H2H Saltend and the acquisition of Triton Power in SSE Thermal And Equinor To Acquire Triton Power In Acceleration Of Low-Carbon Ambitions.
In the related post, I added up all the power stations and wind farms, that are owned by SSE Thermal and it came to a massive 9.1 GW, which should all be available by 2027.
Collaboration Between SSE Thermal And Equinor
The press release also says this about collaboration between SSE Thermal and Equinor.
The two companies are also collaborating on major hydrogen projects in the Humber. Keadby Hydrogen Power Station could be one of the world’s first 100% hydrogen-fuelled power stations, while Aldbrough Hydrogen Storage could be one of the world’s largest hydrogen storage facilities. In addition, they are developing Peterhead Carbon Capture Power Station in Aberdeenshire, which would be a major contributor to decarbonising the Scottish Cluster.
This collaboration doesn’t lack ambition.
I also think, that there will expansion of their ambitions.
Horticulture
Lincolnshire is about horticulture and it is a generally flat county, which makes it ideal for greenhouses.
I wouldn’t be surprised to see a large acreage of greenhouses built close to the Humber carbon dioxide system, so that flowers, salad vegetables, soft fruit, tomatoes and other plants can be grown to absorb the carbon dioxide.
It should also be noted that one of the ingredients of Quorn is carbon dioxide from a fertiliser plant, that also feeds a large tomato greenhouse.
We would have our carbon dioxide and eat it.
Other Uses Of Carbon Dioxide
Storing carbon dioxide in depleted gas fields in the North Sea will probably work, but it’s a bit like putting your rubbish in the shed.
Eventually, you run out of space.
The idea I like comes from an Australian company called Mineral Carbonation International.
- I wrote about their success at COP26 in Mineral Carbonation International Win COP26 Clean Energy Pitch Battle.
- The company has developed the technology to convert carbon dioxide into building products like blocks and plasterboard.
- Their mission is to remove a billion tonnes of CO2 by 2040 safely and permanently.
We would have our carbon dioxide and live in it.
I also think other major uses will be developed.
A Large Battery
There is the hydrogen storage at Aldbrough, but that is indirect energy storage.
There needs to be a large battery to smooth everything out.
In Highview Power’s Second Commercial System In Yorkshire, I talk about Highview Power’s proposal for a 200MW/2.5GWh CRYOBattery.
This technology would be ideal, as would several other technologies.
Conclusion
Humberside will get a giant zero-carbon power station.
Equinor Is Counting On Tax Breaks With Plans For North Sea Oilfield
The title of this post, is the same as that, of this article in The Times.
These paragraphs outline the project.
Norway’s state-owned oil company is pushing ahead with plans to develop Britain’s biggest untapped oilfield after confirming that it stands to benefit from “helpful” tax breaks introduced alongside the windfall levy.
Equinor could lower its windfall tax bill by as much as £800 million in the years to come thanks to investment relief if it develops the Rosebank field, according to Uplift, a campaign group.
Rosebank, to the west of Shetland, could cost £4.1 billion to develop and may account for about 8 per cent of British oil output in the second half of this decade, producing 300 million barrels of oil by 2050.
Equinor said yesterday that it hoped to take a final investment decision on the field by next year and to start production by 2026. It has applied for environmental approval from the government.
Needless to say Greenpeace are not amused.
We Have Both Long Term And Short Term Energy Problems
In the UK, energy is generally used as electricity or gas and to power industry and transport.
Electricity
In the long term, we need to decarbonise our electricity production, so that all our electricity is produced from zero-carbon sources like nuclear, solar, tidal, wave and wind.
- As I write this, our electricity production is around 26.8 GW of which 62 % is coming from renewable sources.
- Surprisingly around 45 % of the renewables is coming from solar. Who’d have ever thought that in an predominantly-grey UK?
- As we have committed to around 50 GW of wind power by 2030 and the 3.26 GW Hinckley Point C will be on stream by the end of the decade, the long term future of electricity production looks to be fairly secure.
- It would be even more secure, if we added around 600 GWh of storage, as proposed in Highview Power’s Plan To Add Energy Storage To The UK Power Network, which would be used as backup when the sun doesn’t shine and the wind doesn’t blow.
It looks to me, that our long term electricity problem is capable of being solved.
For the next few years, we will need to rely on our existing gas-fired power stations until the renewables come on stream.
Gas
Gas could be more of a problem.
- I wouldn’t be surprised to see a lot of resistance to the replacement of natural gas for heating, cooking and industrial processes.
- Natural gas is becoming increasingly difficult to source.
- As I said in the previous section, we will still need some gas for electricity generation, until the massive wind farms are completed.
On the other hand, there is HyDeploy.
I like the HyDeploy concept, where up to 20 % of hydrogen is blended with natural gas.
- Using a blend of hydrogen and natural gas doesn’t require any changes to boilers, appliances or industrial processes.
- The hydrogen blend would make the most of our existing world class gas network.
- Customers do not require disruptive and expensive changes in their homes.
- Enormous environmental benefits can be realised through blending low carbon hydrogen with fossil gas.
- The hydrogen blending could happen, where the natural gas enters the network at terminals which receive gas from the UK continental shelf or where liquified natural gas is imported.
- Alternatively, it may be possible to surround a gas production platform with an offshore wind farm. This could enable hydrogen production and blending to be performed offshore.
The amount of gas we need would drop by twenty percent.
In The Mathematics Of Blending Twenty Percent Of Hydrogen Into The UK Gas Grid, I calculated that 148.2 tonnes per hour of hydrogen would be needed, to blend twenty per cent of hydrogen into UK natural gas supplies.
I also said this about the electricity needed.
To create 148.2 tonnes per hour of hydrogen would need 8,180.64 MW of electricity or just under 8.2 GW.
I also calculated the effect of the hydrogen on carbon dioxide emissions.
As twenty percent will be replaced by hydrogen, carbon dioxide emission savings will be 24,120,569.99 tonnes.
I believe that generating the 8.2 GW of electricity and delivering the 148.2 tonnes per hour of hydrogen is feasible.
I also believe that HyDeploy could be a valuable way to reduce our demand for natural gas by twenty per cent.
Transport
Not every vehicle, ship, aircraft and train can be powered by electricity, although batteries will help.
Hydrogen will help, but we must also develop our capability for sustainable fuels made from rubbish diverted from landfill and biologically-derived ingredients like used cooking oil.
Summing Up Our Long Term And Short Term Energy Problems
We obviously have got the problem of creating enough renewable energy for the future, but there is also the problem of how we keep everything going in the interim.
We will need gas, diesel, petrol and other fossil fuel derived products for the next few years.
Is Rosebank Our Short Term Solution?
This page on the Equinor web site is entitled Rosebank Oil And Gas Field.
This introductory paragraph described the field.
Rosebank is an oil and gas field 130 kilometres off the coast of the Shetland Islands. Equinor acquired the operatorship in 2019 and has since then been working to optimise and mature a development solution for the field together with our partners.
Could the field with its resources of oil and gas, be just the sort of field to tide us over in the next few difficult years.
But given the position, it will surely not be an easy field to develop.
These two paragraphs set out Equinor’s strategy in developing the field.
Equinor believes the field can be developed as part of the UK Government North Sea Transition deal, bringing much needed energy security and investment in the UK while supporting the UKs net zero target. According to a socioeconomic study (see link below) based on data and analysis by Wood Mackenzie and Voar Energy, if sanctioned Rosebank is estimated to create GBP 8.1 billion of direct investment, of which GBP 6.3 billion is likely to be invested in UK-based businesses. Over the lifetime of the project, Rosebank will generate a total of GBP 24.1 billion of gross value add (GVA), comprised of direct, indirect and induced economic impacts.
Equinor together with our partners are working with the supply chain to ensure that a substantial part of investment comes to Scotland and the UK. A supplier day was held in Aberdeen in partnership with EIC in order to increase the number of local suppliers to tender.
Note.
- The sums that could accrue to the UK economy are worthwhile.
- The Government North Sea Transition Deal is worth a read.
- A lot of the deal is about converting oil and gas skills to those of a renewable energy economy.
Planned properly, we should get all the oil and gas we need to get through difficult years.
I particularly like these two paragraphs, which are towards the end of the Government North Sea Transition Deal.
Through the Deal, the UK’s oil and gas sector and the government will work together to deliver
the skills, innovation and new infrastructure required to decarbonise North Sea oil and gas
production as well as other carbon intensive industries. Not only will it transform the sector in
preparation for a net zero future, but it will also catalyse growth throughout the UK economy.
Delivering large-scale decarbonisation solutions will strengthen the position of the existing UK
energy sector supply chain in a net zero world, securing new high-value jobs in the UK,
supporting the development of regional economies and competing in clean energy export
markets.
By creating the North Sea Transition Deal, the government and the UK’s oil and gas sector are
ambitiously seeking to tackle the challenges of reaching net zero, while repositioning the UK’s
capabilities to serve the global energy industry. The Deal will take the UKCS through to
maturity and help the sector pivot towards new opportunities to keep the UK at the forefront of
the changing 21st century energy landscape.
I believe that developing Rosebank could enable the following.
- The oil and gas we need in the next few years would be obtained.
- The economic situation of the UK would be improved.
- The skills and techniques we need to decarbonise the UK would be delivered.
- Net-zero would be reached in the required time.
- Jobs will be created.
- The export of surplus oil and gas.
I strongly believe that developing the Rosebank field would be worthwhile to the UK.
I have some other thoughts.
Electrification Of Platforms
This page on the Equinor web site is entitled Electrification Of Platforms.
This paragraph explains what that means.
Electrification means replacing a fossil-based power supply with renewable energy, enabling a reduction in greenhouse gas emissions. Equinor is fully committed to reducing emissions from our offshore oil & gas production.
Note.
- Typically, platforms use gas turbine engines running on natural gas to provide the electricity needed on the platform.
- Platforms in the future will get their electricity from renewable sources like wind and will have an electricity cable to the shore.
- Rosebank will be powered in this way.
This document on the Equinor web site is entitled Rosebank: Investing In Energy Security And Powering A Just Transition, which has a section called How Is Rosebank Different?, where this is said.
The key difference of Rosebank compared to other oil fields is that it
aims to draw on new technology applications to help reduce carbon
emissions from its production, through FPSO electrification.Building offshore installations that can be powered by electricity reduces
reliance on gas powered generators which are the biggest source
of production emissions. The electrification of UKCS assets is vital to
meeting the North Sea Transition Deal’s target of reducing production
emissions by 50% by 2030, with a view to being net zero by 2050.Electrification of Rosebank is a long-term investment that will drastically
cut the carbon emissions caused by using the FPSO’s gas turbines for
power. Using electricity as a power source on Rosebank results in a
reduction in emissions equivalent to taking over 650,000 cars off the
road for a year compared with importing 300 million barrels of oil from
international sources.
Note.
- An FPSO is a Floating Production Storage And Offloading Unit, which is the method of production, that Equinor have chosen for the Rosebank field.
- If we are going to extract fossil fuels then we must extract them in a manner, that doesn’t add to the problem by emitting extra carbon dioxide.
- We will probably extract fossil fuels for some years yet, as they are the easiest route to some important chemicals.
- I also believe that we will increasingly find uses for any carbon dioxide captured in combustion and chemical processes.
I already know of a farmer, who heats greenhouses using a gas-powered combined heat and power unit, who pipes the carbon dioxide to the tomatoes in the greenhouses.
Despite what Greenpeace and others say, carbon dioxide is not all bad.
Energy Security
The last page of this document on the Equinor web site is entitled Rosebank: Investing In Energy Security And Powering A Just Transition, is entitled Energy Security.
Look at the numbers.
- £8.1 billion – Total field investment with 78% of this being spent in the UK
- 1600 – Estimated peak number of direct FTE jobs
- £24.1 billion – Estimated gross value add
- 8 % – Of UK oil production from Rosebank to 2030
- 39 million cubic feet per day – Average daily gas production over the first 10 years of field life, equivalent to almost twice Aberdeen’s daily gas consumption
- 250kt CO2 – Carbon avoided by reusing existing FPSO
And if you have time read it fully.
Could The Rosebank FPSO Be Powered By Floating Offshore Wind?
Floating wind turbines are now being installed around the world.
- They can use the largest turbines.
- Some designs perform in the roughest of seas.
- They have a high capacity factor.
- They are generally brought into a suitable port for servicing and updating.
- Floating wind farms can be connected to floating substations
There is at least 20 GW of floating wind turbines planned for UK waters.
So could an appropriately-sized floating wind farm be placed near the Rosebank FPSO to provide it with electricity?
I don’t see why not, if there were some energy storage in the system, for when the wind wasn’t blowing.
Floating Offshore Wind Close To The Rosebank FPSO Would Be Challenging
Rosebank is an oil and gas field 130 kilometres off the West coast of the Shetland Islands.
That would be a challenging location for floating wind turbines.
But solving the installation problems would set precedents for floating wind farms all over the world.
Could The Rosebank FPSO Handle Hydrogen From Floating Offshore Wind?
It would surely be possible to put an electrolyser in the system somewhere, so that hydrogen was also stored in the tanks of the FPSO.
I also don’t think it unfeasible, that twenty percent of hydrogen could be blended into the natural gas to create the low-carbon natural gas, that has been proposed by the HyDeploy project.
Long Duration Energy Storage Would Reduce The UK’d Gas Usage By 10 Megatonnes By 2035
The title of this post, is the same as that of this press release on the Highview Power web site.
The press release gives these three bullet points.
- UK has wasted over 1,300 GWh of wind since the start of the energy crisis in September 2021 due to an inability to store excess generation – enough to power 500,000 homes a day.
- A new survey from YouGov, commissioned by Highview Power, reveals that 43% of UK adults think the UK imports too much gas, rising to 54% among Conservative voters at the 2019 General Election.
- Long-duration energy storage (LDES) would reduce UK’s gas usage by 10 megatonnes in 2035 and save the grid around £2 billion a year, passing on savings of up to £50 a year.
In Highview Power’s Plan To Add Energy Storage To The UK Power Network, I talked about Highview Power’s possible 30 GWh CRYOBattery.
This project has not been fully revealed and I expect something will be announced before the end of this year.
Rio Tinto’s Big Energy Project Attracts Multiple Bidders
The title of this post, is the same as that of this article on Mining Technology.
The article has this subtitle.
The company seeks to offset its power consumption with a massive renewable plant.
These two paragraphs introduce the project.
British and Australian mining giant Rio Tinto has attracted multiple bids for a massive renewable power infrastructure project.
The company currently seeks suppliers to build up to 4GW of renewable generation for its alumina and aluminium operations in Queensland, Australia. Speaking to the Melbourne Mining Club, the company’s CEO of Australia, Kellie Parker, said that it had received proposals for “a lot more than 4GW”. Parker also said that construction of the project “would not be easy” due to the cost of construction for Australian projects.
In the UK, we may talk of wind farms like Hornsea, which could produce 6 GW, but the Aussies can produce similar amounts of energy from the sun.
This will be the fourth major renewable power development in Australia to be announced in the last few months.
- The Asian Renewable Energy Hub could generate up to 26 GW in Western Australia.
- I wrote about Andrew Forrest’s ambitions in Andrew Forrest Snaps Up Pilbara And Gascoyne Cattle Stations For Green Energy Production.
- The Australia-Asia Power Link will export solar power from Australia to Singapore.
Australia is certainly looking to power the world.
Energy Storage
Rio Tinto are also talking about energy storage, as other systems of this type and size do. Could this be one of a number of Australian projects mentioned on the Highview Power web site?
Could A Highview Power CRYOBattery Use A LNG Tank For Liquid Air Storage?
This Google Map shows a 3D image of liquified natural gas (LNG) tanks at South Hook LNG Terminal near Milford Haven.
Note that images of these tanks under construction on the Internet, show that there is an underground portion of the tanks.
This page on the CIMC-ENRIC web site is entitled Successful Delivery Of 5,000M3 LNG Single Containment Tank Project. The page shows the design of the LNG tank.
As the density of liquid air is 870 kg/m3, a 5,000 cubic metre tank would contain 4,350 tonnes of liquid air at −194.35 °C and atmospheric pressure.
How much energy would be needed to create 4,350 tonnes of liquid air?
In this document, this is said about compressing natural gas with an electric drive.
It is the most-energy efficient technology with 230 kWh per ton of LNG.
As air and natural gas have molecules of similar weight, would 230 kWh per tonne be applicable to liquid air.
If it is, then around a GWh of electricity will be needed to create the liquid air.
This Wikipedia entry is entitled Cryogenic Energy Storage and describes Highview Power’s CRYOBattery.
This section describes the operation of the CRYOBattery.
When it is cheaper (usually at night), electricity is used to cool air from the atmosphere to -195 °C using the Claude Cycle to the point where it liquefies. The liquid air, which takes up one-thousandth of the volume of the gas, can be kept for a long time in a large vacuum flask at atmospheric pressure. At times of high demand for electricity, the liquid air is pumped at high pressure into a heat exchanger, which acts as a boiler. Air from the atmosphere at ambient temperature, or hot water from an industrial heat source, is used to heat the liquid and turn it back into a gas. The massive increase in volume and pressure from this is used to drive a turbine to generate electricity.
Note.
- The Claude cycle is described in this Wikipedia entry.
- The liquid air takes up one-thousandth of the volume of the gas.
- Wikipedia suggests that Highview claim the process has a round trip efficiency of 70 %.
Having done calculations in the past with chemical reactions in a series of large vessels, the dynamics can be strange and I wouldn’t be surprised that as Highview learn more about the process and add more and better ways of recycling heat and coolth, efficiencies will improve.
Certainly, in the process I mathematically-modelled in the 1970s, when I worked for ICI, I remember that one large reaction vessel performed better than four or five smaller ones with the same total volume.
Hence my thought that perhaps one large containment tank could be the most efficient design.
I also think, that the design of LNG tanks must have improved significantly over the last few years, as the transport of LNG has increased in importance.
Form Energy And The UK
This article on the Telegraph, which is entitled Britain Will Soon Have A Glut Of Cheap Power, And World-Leading Batteries To Store It, is proving to be a mine of information about the development of the UK Power Network.
Reliable information about US startup; Form Energy has been hard to find.
But the Telegraph article has these three paragraphs on Form Energy.
Form Energy in Boston – backed by Jeff Bezos and Bill Gates – is working on an iron-air “rust” battery based on the reversible oxidation of iron pellets. It does not require rare and polluting minerals such as vanadium, and will have a 100-hour range.
“The modules will produce electricity for one-tenth the cost of any technology available today for grid storage,” the company told Recharge.
Form Energy has been working with National Grid to map out the economics of UK renewables with storage, and how to cope with future curtailment. And it too praises the UK as a global trailblazer, though its pilot project next year will be in Minnesota.
Note.
- Iron certainly, isn’t an exotic material.
- A hundred hour range is claimed.
- If National Grid have been working with Form Energy, is it reasonable to assume, that they have been working with Highview Power?
- Good to see that Form Energy praises the UK as a global trailblazer. I have noted several times, that the Department for Business, Energy and Industrial Strategy seems to be well-advised.
Will National Grid put in one of Form Energy’s batteries? It would be a prudent thing to do, to make sure you get the best.
Highview Power’s Second Commercial System In Yorkshire
This is all that Highview Power say about their proposed system in Yorkshire, on their web site.
Highview Power’s second commercial renewable energy power station in the UK is a 200MW/2.5GWh facility in Yorkshire. This is the first of 18 sites for UK wide deployment strategically located to benefit from the existing transmission infrastructure.
I have a few thoughts.
How Does The Size Of This System Fit With Other Systems?
According to the Highview Power web site the Manchester system is a 50MW/300MWh facility, but Wikipedia has this system as a 50MW/250MWh.
In this article on the Telegraph, which is entitled Britain Will Soon Have A Glut Of Cheap Power, And World-Leading Batteries To Store It, it is stated that they are planning a battery with this specification, location and timeline.
- 2.5 GW output
- 30 GWh of storage
- Located on Humberside
- Delivery in late 2024.
This CRYOBattery is an absolute monster.
Will The Humberside CRYOBattery Be Built At Creyke Beck Substation?
In Highview Power’s Plan To Add Energy Storage To The UK Power Network, I came to the conclusion, that the Humberside CRYOBattery will most likely be built near Creyke Beck substation, which is close to Cottingham.
- Dogger Bank A, Dogger Bank B and Hornsea 4 offshore wind farms will all be connected to the Creyke Beck substation.
- These wind farms have a total capacity of 3.4 GW.
- The Humberside CRYOBattery, now looks to have a maximum output of 2.5 GW.
- It looks like the Humberside CRYOBattery would be a well-matched backup to the three planned wind farms and perhaps even a few more turbines.
Building the Humberside CRYOBattery at Creyke Beck substation would appear to be a sensible decision.
Is Cottingham In Humberside, Yorkshire Or Both?
The Wikipedia entry for the village is named Cottingham, East Riding of Yorkshire, says this.
A golf course and leisure club on Wood Hill Way, and a major (400/275 kV AC) electricity substation “Creyke Beck”, lie just outside the formal boundaries of the parish, within Skidby civil parish.
Skidby is definitely in Yorkshire.
Where Are The Other Seventeen Sites?
The Yorkshire facility is indicated to be one of 18 sites on the Highview Power web site. Where are the other seventeen?
All we know is that they will be strategically located to benefit from the existing transmission infrastructure.
This is said in the Wikipedia entry, which is entitled High-Voltage Substations In The United Kingdom.
In 2020 there were 179 400 kV substations and 137 275 kV substations.
He who pays the money, makes the choice!
Has The Company Changed Direction?
I wrote Highview Power Names Rupert Pearce Chief Executive Officer on April 12th, 2022.
- Since then, the Vermont and Chile projects have disappeared from the web site and projects in Yorkshire and Australia have been added.
- The web site has also been improved.
- As new CEOs often do, is Rupert Pearce refocussing the company?
Are they also looking in detail at current projects?
Has The Yorkshire Project Grown Substantially?
Consider.
- National Grid are a company that has improved its image and engineering in recent years.
- It has shown it can obtain finance for infrastructure from the City of London and respected financial institutions.
- National Grid probably have extensive computer models of their electricity network.
- National Grid knows it must add energy storage to their electricity network.
- National Grid pays almost a billion pounds a year to wind farm operators to shut them down.
Eventually saving up to a billion pounds would be a good reason to have a small bet on promising technology.
Did Rupert Pearce ask his engineers to design the largest CRYOBattery they can?
Did National Grid have a count up sand find that twenty CRYOBatteries would cover all the strategic points on their transmission infrastructure?
According to the figures on the Highview Power web site (200 MW/2.5 GWh), eighteen systems like the one proposed for Yorkshire would have.
- A total output of 3.6 GW
- A total storage capacity of 45 GWh
The figures given in the article in the Telegraph (2.5 GW/30 GWh) for the very large system, would mean that twenty systems would have.
- A total output of 50 GW
- A total storage capacity of 600 GWh
These figures are between thirteen and fourteen times larger than those originally proposed.
Building The System
The Highview Power web site, says this about the deployment of eighteen systems.
UK wide deployment strategically located to benefit from the existing transmission infrastructure.

Could 30 GWh of liquid-air storage be accommodated on the site?
I can see a large insulated sphere, partly buried in the ground being used.
Designing, building and testing the first system will probably be the most difficult part of the project.
- But once the first system is successfully working reliably, the roll-out of other systems can be started.
- The biggest problem will probably be planning permissions, so the systems must be designed to be sympathetic to the local environment.
I can certainly see, twenty of these systems in the UK, but how many others will we see worldwide?

Highview Power’s Plan To Add Energy Storage To The UK Power Network
The plan was disclosed in this article on the Telegraph, which is entitled Britain Will Soon Have A Glut Of Cheap Power, And World-Leading Batteries To Store It, by Rupert Pearce, who is Highview’s chief executive.
His plan is to build twenty of Highview Power’s CRYOBatteries around the country.
- Each CRYOBattery will be able to store 30 GWh.
- Each CRYOBattery will be one of the largest batteries in the world.
- They will have three times the storage of the pumped storage hydroelectric power station at Dinorwig.
- They will be able to supply 2.5 GW for twelve hours, which is more output than Sizewell B nuclear power station.
The first 30 GWh CRYOBattery is planned to be operational by late 2024.
- It will be built on Humberside.
- Humberside is or will be closely connected to the Dogger Bank, Hornsea and Sofia wind farms.
- When fully developed, I believe these wind farms could be producing upwards of 8 GW.
The Telegraph quotes Rupert Pearce as saying this.
We can take power when the grid can’t handle it, and fill our tanks with wasted wind (curtailment). At the moment the grid has to pay companies £1bn a year not to produce, which is grotesque.
I certainly agree with what he says about it being a grotesque practice.
It sounds to me, that Rupert’s plan would see Highview Power in the waste electricity management business.
- The wasted wind would just be switched to the Humberside CRYOBattery, if there was too much power in the area.
- The CRYOBattery might be conveniently located, where the wind farm cables join the grid.
- Dogger Bank A and B wind farms are connected to Creyke Beck substation, which is North of the Humber.
- Hornsea 1 and Hornsea 2 wind farm are connected to Killingholme substation, which is South of the Humber.
- Hornsea 3 wind farm will be connected to Norfolk.
- Hornsea 4 wind farms will be connected to Creyke Beck substation
- It looks like the combined capacity of Dogger Bank A, Dogger Bank B and Hornsea 4 could be around 3.4 GW.
- Sofia wind farm will be connected to Lazenby substation near Redcar.
- As the CRYOBattery is buying, selling and storing electricity, I would assume that there’s money to be made.
This Google Map shows Creyke Beck substation.
Note.
- It is a large site.
- Creyke Beck Storage have built a 49.99 MW lithium-ion storage battery on the site.
- The Northern part of the site is used to store caravans.
- It looks like the combined capacity of Dogger Bank A, Dogger Bank B and Hornsea 4 could be around 3.4 GW.
It looks like a 30 GWh CRYOBattery with a maximum output of 2.5 GW would be an ideal companion for the three wind farms connected to Creyke Back substation.
The combination could probably supply upwards of 2.5 GW to the grid at all times to provide a strong baseload for Humberside.
Conclusion
Will the income from the Humberside CRYOBattery be used to fund the next CRYOBattery?
I very much think so as it’s very sensible financial management!
