Energy Dome To Partner With Ørsted For Energy Storage
The title of this post, is the same as that of this article on CleanTechnica.
This paragraph from the long article, gives details of the partnership.
I got a press release from Energy Dome this past week telling me that its technology has attracted interest from Ørsted, the Danish company that is a global leader in wind turbine technology. The two companies have signed a memorandum of understand that will allow them to explore the feasibility of deploying of a 20 MW/200 MWh Energy Dome facility at one or more Ørsted sites.
Is this the first deal between a major wind farm developer and a third-party non-lithium battery developer?
The article on CleanTechnica is very much a must-read and it goes into detail about the technology behind Energy Dome’s unique CO2 battery.
These are my thoughts.
Energy Dome Has A UK Office
Is this significant?
- The UK has a large need for energy storage than any other country in Europe, as we have lots of renewable energy generation, that could benefit.
- Most Italians speak good English.
- The UK government is prepared to develop innovative payment schemes for renewable energy.
- Their is a long history of Italians in the United Kingdom.
- Italians are distributed all over the UK.
- Some of the best Italian chefs are resident in the UK.
- The UK market is not biased against foreign customers.
I wouldn’t be surprised, if Energy Dome targeted the UK market.
Ørsted
Some facts about Ørsted.
- Ørsted are the largest energy company in Denmark.
- As of January 2022, the company is the world’s largest developer of offshore wind power by amount of built offshore wind farms.
- Ørsted own or have shares in fifteen offshore wind farms in the UK, which have a total capacity of 8731 MW.
- Ørsted have no interests in onshore wind in the UK.
- Ørsted divested itself of its last onshore wind farm in 2014.
The fact that Ørsted has partnered with Energy Dome is highly significant, as in my experience large powerful companies don’t partner with smaller start-ups without a lot of technical due diligence.
Use Of A 20 MW/200 MWh Energy Dome
I suspect that Ørsted will deploy their first 20 MW/200 MWh Energy Dome facility with onshore wind.
When you compare the 20 MW/200 MWh Energy Dome with the 1.5 GW/30 GWh Coire Glas pumped storage hydroelectric power station, it is only a fairly small storage system, in both terms of output and storage.
As an Electrical and Control Engineer, I suspect that will mainly be used with smaller offshore wind farms to smooth the output, rather than as serious stand-by power for a large GW-sized wind farm.
In the UK, Ørsted has three smaller wind farms, that could be suitable.
- Barrow – 90 MW
- Burbo Bank – 90 MW
- Gunfleet Sands 3 – 12W
Note.
- All are a few miles offshore.
- Gunfleet Sands 3 was built to test two l6 MW turbines.
- All the three wind farms are over twelve years old.
I think it is unlikely, that any of these three wind farms will be fitted with the Energy Dome.
I do believe though, that a 20 MW/200 MWh Energy Dome facility could work well with the Barrow wind farm, as it is a simple farm not connected to any others.
Are The Tories Bluffing About Fracking?
I’ve just listened to a Treasury Minister (Chris Philp (?)) on the BBC and he didn’t mention fracking.
But he did mention more oil and gas in the North Sea, where there is a project agreed between the British and Scottish governments called INTOG, which aims to innovatively cut carbon emissions in the North Sea and possibly extract smaller amounts of gas and oil from existing wells.
As you know, I think fracking is irrelevant. It will take a few years to deliver substantial amounts of gas and we can extract more from the North Sea and by repurposing existing wells.
We might even find one or two existing wells, that could be converted to much-needed gas storage.
I also believe that the cash flow in taxes and leases from offshore wind will be astronomic and it can be used to finance borrowing. We did the same with Artemis to finance the company against future sales. But we were only borrowing millions. We used to parcel up all our leases from companies like Shell, NASA and BP and effectively sell them to Lloyds Bank at a discount.
I’m sure that a clever banker could find a mechanism, that converts future income from offshore wind into a magic money tree for today. Is that what Kwasi Kwarteng has done, in order to cut taxes?
The one problem with offshore wind with the public, is that putting in the cables arouses the NIMBYs. It should also be born in mind, that a lot of the grid connections, go through Tory seats, where NIMBYs are very much against more cables.
So I do wonder, if Moggy has announced the start of fracking to give the NIMBYs a target, so they allow the efficiency of offshore oil and gas to be improved and offshore wind farms to be built without hindrance.
Perhaps Moggy should concentrate on the most important thing that our offshore wind industry needs. This is an innovative pricing mechanism for energy storage, that does the following.
- Allows investors to get a similar return on energy storage to that that they get for offshore wind farms, onshore solar farms and interconnectors.
- Encourages the building of more energy storage.
- Assists in the development of novel energy storage ideas.
As one estimate says we need 600 GWh of energy storage in the UK, sorting this pricing mechanism, can’t come soon enough.
The previous government was talking about this, as I wrote in Ministerial Roundtable Seeks To Unlock Investment In UK Energy Storage.
So continue the conversation, Moggy!
Thoughts On The Mini-Budget
This article on the BBC is entitled At A Glance: What’s In The Mini-Budget?.
If nothing else KK has whipped up a storm, with the most tax-cutting budget in decades.
But!
According to my calculations in Will We Run Out Of Power This Winter?, the planned offshore wind that will be installed between 2022 and 2027 will be at least 19 GW. About 3 GW of this offshore wind is already producing electricity.
To this must be added 3.26 GW for Hinckley Point C, 2 GW for solar and 0.9 GW for onshore wind in Scotland, which will be developed by 2027.
So we have 25.2 GW for starters.
Following on from this is the 27.1 GW from ScotWind, about 4 GW from the Celtic Sea, 3 GW from Morecambe Bay and 10 GW from Aker’s Northern Horizons. All of these are firm projects and some are already being planned in detail.
These wind and solar farms are the collateral for KK’s borrowing.
The corporate tax changes will hopefully attract world class energy and manufacturing companies to set up UK-domiciled subsidiaries to develop more offshore wind farms and manufacture the turbines and the electrical gubbins close to where they will be installed.
As more wind farms are built, many GW of electricity and tonnes of hydrogen will be exported to Europe.
Note that 1 GW for a day costs around £ 960,000 and for a year costs £350.4 million.
A big benefit of all this electricity, will be that we won’t need to frack.
Technologies like green hydrogen, that will be created by electrolysis will reduce our need for gas.
We might develop a gas field like Jackdaw, to give us gas for a backup with a few gas-fired power stations, for when the wind doesn’t blow, but gas will only have a minor roll.
The force of the maths is with KK!
Have We Missed The Boat On Fracking?
I have just re-read my post from October 2019, which was entitled Fracking Hell…Is It The End?, where these were my conclusions.
- Fracking for hydrocarbons is a technique that could be past its sell-by date.
- The use of natural gas will decline.
- INEOS could see hydrogen as a way of reducing their carbon footprint.
- The heating on all new buildings should be zero carbon, which could include using hydrogen from a zero-carbon source.
- There are reasons to think, that electricity from wind-farms creating hydrogen by electrolysis could replace some of our natural gas usage.
So will the Government’s lifting on the ban on fracking make any difference?
The announcement is detailed in this article on the BBC, which is entitled Fracking Ban Lifted, Government Announces.
These are my thoughts.
Fracking Is Not A Quick Fix
My personal view is that to achieve any significant amounts of gas from fracking will take some years, so it is not something that will be available in the short term.
Opposition To Fracking Won’t Help
There are very few inhabitants of the UK, who are enthusiastic about fracking.
Opposition to fracking will make it less likely to be the feasible short term fix we need in the UK.
Suppose There Was An Earthquake Near To A Fracking Site
Fracking also has the problem, that if there were to be a small earthquake near to a site, even if it was very likely to have not been caused by fracking, it would result in massive public uproar, which would shut down all fracking in the UK.
This to me is a big risk!
Would The Jackdaw Oil And Gas Field Be A Medium Term Solution?
- In Shell’s Jackdaw Gas Field Given Go-Ahead By Regulators, I wrote about Shell’s Jackdaw field, which has been given the go-ahead.
- It could be able to provide 6 % of North Sea gas production.
- It should be fully operational by 2025.
I believe that with other gas field developments and imports, Jackdaw could keep us supplied with enough gas until the end of the decade.
Future Renewable Electricity Production
In Will We Run Out Of Power This Winter?, I summarised the likely yearly additions to our offshore wind power capacity in the next few years.
- 2022 – 3200 MW
- 2023 – 1500 MW
- 3024 – 2400 MW
- 2025 – 6576 MW
- 2026 – 1705 MW
- 2027 – 7061 GW
Note.
- Ignoring 2022 as it’s going, this totals to 19.2 GW.
- Hopefully, by the end of 2027, Hinckley Point C will add another 3.26 GW
- According to Wikipedia, there are currently 32 active gas fired combined cycle power plants operating in the United Kingdom, which have a total generating capacity of 28.0 GW.
I think it is not unreasonable to assume that some of the electricity will enable some of our gas-fired power stations to be stood down and/or mothballed.
Gas consumption would be reduced and some power stations would be held in reserve for when the wind was on strike!
Using Hydrogen To Eke Out Our Gas
Consider.
- In Lime Kiln Fuelled By Hydrogen Shown To Be Viable, I wrote about how hydrogen can be used instead of or with natural gas to fuel a lime kiln.
- There are other processes, where hydrogen can be used instead of or with natural gas.
- Using more hydrogen will reduce the amount of carbon dioxide emitted.
Perhaps we should strategically build a few huge hydrogen electrolysers, so that some large industrial users can cut back on their natural gas.
Will Energy Storage Help?
Energy storage’s main use is to mop up all the surplus electricity when demand is low at a low price and sell it back, when demand is high.
If we waste less energy, we will use less gas.
Will District Heating Schemes Help?
Consider.
- In Eden Project: Geothermal Heat Project ‘Promising’, I wrote about the Eden Project’s plan to extract heat from a borehole.
- In ‘World-First’ As Bunhill 2 Launches Using Tube Heat To Warm 1,350 Homes, I wrote about a district heating scheme in Islington, that uses heat from the London Underground.
- In Exciting Renewable Energy Project for Spennymoor, I wrote about a district heating scheme, that uses heat from abandoned coal mines.
More schemes like this should be developed, where there is a readily-available source of heat or electricity
Conclusion
As we add more renewables to our energy generation, it appears to me, that our gas usage will decline.
If we were to go fracking, we should have done it a lot earlier, so we can bridge the short term gap.
How To Store Excess Wind Power Underwater
The title of this post, is the same as that of this article on the BBC.
The article talks why batteries are needed and then describes the Ocean Battery.
But one firm, which won a 2022 Best of Innovation award at the CES technology show earlier this year, believes it has the solution.
Dutch startup, Ocean Grazer, has developed the Ocean Battery, which stores energy below the wind farm.
When there is excess electricity the system pumps water from an underground reservoir into tough, flexible bladders that sit on the sea bed. You could think of them like big bicycle inner tubes.
The water in those tubes is under pressure, so when it is released the water flows quickly and is directed through turbines, also on the sea bed, generating electricity when needed.
“The Ocean Battery, is effectively based on the same technology as hydro storage, where water is pumped back through a dam in a river, though we have transformed it into something you can deploy on the sea bed,” says chief executive Frits Bliek.
There is a visualisation of the system and a picture of their prototype.
UK Cleantech Consortium Awarded Funding For Energy Storage Technology Integrated With Floating Wind
The title of this post, is the same as that of this page on the UK Government’s Catapult Offshore Renewable Energy Web Site.
This is the introductory paragraph.
STORE, a UK-based cleantech consortium led by RCAM Technologies Limited, has been awarded £150,000 of funding to develop an advanced subsea energy storage technology manufactured using 3D printed concrete that could help offshore wind farms produce a steady and predictable energy output to the electricity grid.
This paragraph talks of the concept of Marine Pumped Hydro.
STORE is assessing the feasibility of integrating Marine Pumped Hydro (MPH) technology, which stores energy using hollow concrete spheres fitted with a hydraulic turbine and pump, with floating offshore wind plants in UK waters. In addition, the project advances the design of MPH systems and plans a prototype demonstration in the UK.
Note.
- The hollow concrete spheres are 3D-printed in concrete using the technology of RCAM Technologies.
- Spheres are structurally very strong.
- 3D printing of concrete is now mainstream technology and has been extensively used on the Elizabeth Line as I wrote about in The Story Behind The Concrete Panels On The Elizabeth Line.
- There is a visualisation on the Catapult web page, which shows several floating turbines, a floating sub station and several concrete hemispheres sitting on the seabed.
- The energy storage medium is sea water and air, which must be environmentally-friendly.
The technology is described in detail on this page of the STORE consortium web site.
- The spheres are fifteen metres across.
- The spheres can be installed at depths between 150 and 2000 metres.
- The system has a round-trip efficiency is up to 70%, which is similar to pumped storage hydro.
- The design life is 50 to 80 years.
I think that this system has possibilities.
This last paragraph in the Catapult web page gives a look into the future.
As well as improving the reliability and predictability of energy to the electricity grid, the project will support the cross sector transfer of UK offshore expertise and port infrastructure for use in renewable energy and create high-value UK jobs in engineering, construction, and operations and maintenance. This energy storage solution is ideally suited to coupling with floating wind plants and for powering offshore oil and gas assets from renewable energy. The 3D printed concrete also facilitates localized manufacturing and enables low cost fabrication of new and complex shapes that were previously not practical.
I also feel that if the concrete sphere energy storage can be made to successfully work, then the technology can surely be fitted to any offshore wind farm, by just adding the right number of spheres and connecting them to the offshore sub station.
The STORE Consortium
The STORE consortium has a web site, which has a heading of Innovative Subsea Energy Storage.
It describes the technology in this paragraph.
STORE is advancing a subsea energy storage technology called Marine Pumped Hydro (MPH). MPH uses large hollow concrete spheres on the seafloor to store mechanical energy in the form of pressure. MPH charges when seawater is pumped out of the spheres and releases energy to the grid when high-pressure water flows back into the spheres through a turbine. MPH features a patent-pending multi-sphere pod to increase the amount of energy stored and uses efficient 3D concrete printing to reduce manufacturing costs.
It sounds like an engineer with children, has been playing with them and their plastic toys in a bath and has had an Archimedes moment.
The project and its funding is described in this paragraph.
STORE was awarded £150,000 from the Department for Business, Energy & Industrial Strategy Longer Duration Energy Storage Demonstration (LODES) competition. Phase 1 will deliver a Feasibility Study focused on the design and analyses for the UK. Phase 2, if awarded, will design, manufacture, and operate a prototype system at TRL 6.
Note that TRL 6 is Technology Readiness Level 6 and is fully defined on this NASA web page, as having a fully functional prototype or representational model.
There is also an interesting link to the ScotWind N3 wind farm. that I wrote about in ScotWind N3 Offshore Wind Farm.
- This is an unusual floating wind farm with a floating substation.
- Technip and Loch Kishorn port are involved in both the wind farm and STORE.
- Loch Kishorn has a history of building immense concrete structures.
I wouldn’t be surprised if this wind farm would be the location of the prototype system.
Conclusion
This is a brilliant concept.
- It is the ideal energy storage system for offshore wind, as it can turn a wind farm with a variable output into one with a much more constant output.
- It can be retrofitted to existing offshore wind farms.
- It will work with both fixed and floating wind farms.
- The concrete storage spheres can be fully assembled with all their electrical gubbins on shore and towed out, before sinking in the required position.
It also looks like the Department for Business, Energy & Industrial Strategy have got involved and helped with the funding. Someone there seems to know a good idea, when they see it!
RCAM Technologies
Wouldn’t it be a good idea to have a wind turbine with built-in energy storage?
This article on Power Engineering, is entitled Five Long-Duration Energy Storage Projects Get Funding In New York.
One of the projects, from RCAM Technologies is described like this.
To develop a 3D concrete-printed marine pumped hydroelectric storage system that integrates directly with offshore wind development in support of grid resiliency and reduced reliance on fossil fuel plants to meet periods of peak electric demand.
That sounds like an offshore wind turbine with built-in energy storage, that is 3D-printed in concrete.
The RCAM Technologies web site is all about 3D-printed concrete.
- It looks like they can build taller wind farm towers, than you can make with steel.
- It appears offshore wind turbine tower with integrated foundations can be built on-site.
- Material can be 100 % locally-sourced.
- The next step could be to build some form of pumped storage into the tower.
- They are experimenting with storing energy as pressure in 3D-printed concrete spheres. The New York grant will help fund this.
- High Speed Two is using 3D-printing of concrete, as I wrote about in HS2 Utilising UK-First Pioneering 3D Concrete Printing On Project.
The company has offices in Colorado, California and Edinburgh.
Conclusion
This technology could be on the right track. Read their web site.
Five Long-Duration Energy Storage Projects Get Funding In New York
The title of this post, is the same as that of this article on Power Engineering.
These are the two opening paragraphs, which outline the state’s ambitions.
New York awarded $16.6 million in funding for five long-duration energy storage projects and made another $17 million available for projects that advance development of long-duration energy storage technologies, including hydrogen.
The state’s larger goal is to install 3,000 MW of energy storage by 2030 to help integrate renewables. New York wants to eventually develop 6,000 MW.
The article then lists the projects, which I will look at in separate posts.
Can We Move The Equilibrium Point Of The Energy Market?
Equilibrium In Systems
As a Control Engineer, I believe that most systems eventually end up in a state of equilibrium.
How many football batches have you watched between two evenly-matched teams that have ended, where the statistics are even and the match has ended in a nil-nil draw or a win by one goal.
Now suppose one manager makes an inspired substitution, one important player gets injured or one player gets sent off.
One team will have an advantage, the statistics will no longer be even and one team will probably win.
The equilibrium point will have been shifted.
Zopa’s Stable Peer-to-Peer Lending System
I used Zopa’s peer-to-peer lending system for several years and found it a very stable system, that over the years paid a steady return of between four and five percent before tax.
I even developed a method to maximise my savings income, which I wrote about in The Concept Of Hybrid Banking.
It was a sad day for me, when Zopa closed its ground-breaking peer-to-peer lending system.
As a Control Engineer, I believe that Zopa’s strength was a well-written computerised algorithm, that matched lenders and borrowers and spread the risk.
- There was no bias in the system, introduced by personal prejudices.
- The algorithm was agnostic and judged all borrowers on their profiles and credit ratings alone.
- Money was allocated under fair rules for borrowers.
- I never borrowed from Zopa, but from my experience of owning half of a finance company, their terms were the most customer-friendly I’ve ever seen.
Someone will go back to the basics of peer-to-peer lending and it can’t be soon enough for both savers and borrowers.
Zopa In Troubled Times
Over the years that I invested in Zopa, my returns stayed very much the same, as the algorithm seemed to be able to maintain sufficient difference between lenders’ returns and borrowers’ rates. I also suspect the dynamics of savvy lenders and borrowers helped to stabilise both the system and the difference between rates.
It even worked through the Banking Crisis of 2008 and other mini-hiccups along the way.
My Conclusion About Zopa
As someone, who knows computing well, I would rate Zopa, one of the best computer systems, I’ve ever seen.
But it showed how a large transactional system can work well.
One of the keys to its success and smooth operation was that the computer was totally in control and it took all transaction decisions without direct human intervention.
The Energy Market
The energy market is a network of energy providers and users.
It is controlled by complicated rules and it has settled into an equilibrium, which involves.
- Importation of energy, which I suspect is not at a low price
- Some high priced energy generators, based on gas, which has a high-price, due to Putin’s war.
- Waste of wind energy due to lack of energy storage.
- The intermittency of renewable sources.
- A lack of gas storage, means that we probably get the wrong end of fluctuations in the gas price.
This results in a high price to consumers.
Can We Move The Equilibrium Point Of The Energy Market?
And we also need to move it quickly to a more favourable place, which benefits everybody!
As a Control Engineer, I believe that there are five ways to move the equilibrium point.
- Stop Putin’s war.
- Increase gas storage.
- Generate more low-cost electricity.
- Increase electricity storage.
- Improve the control algorithm.
I will now look at each in more detail.
Stopping Putin’s War
Giving in to Putin’s ambitions, would be an easy way to solve our energy crisis. But at what cost?
My parents generation, watched as Nazi Germany took over Austria and Czechoslovakia, whilst the world did nothing.
- We mustn’t repeat that mistake.
- We must not flinch in our support of the Ukraine.
- We must be ready to support Moldova, Finland and the Baltic States if Putin expands his ambitions.
I do wonder, if Boris will turn up with Churchillian-style anti-Putin rhetoric all over Eastern Europe.
Increasing Gas Storage
The major gas storage facility is Rough, which is handily close to the Easington gas terminal.
The facility needs maintenance and this paragraph from the Wikipedia entry gives the current status.
In May 2022, the Secretary of State for Business, Energy and Industrial Strategy, Kwasi Kwarteng, began talks with the site’s owners with a view to reopening the site to help ease the ongoing cost-of-living crisis in the United Kingdom. In June 2022, owners Centrica submitted an application to the North Sea Transition Authority (NSTA), the licencing authority for the UK Government, to reopen the facility. Approval was granted in July. Subsequently, Centrica indicated that they are working hard to restore storage operations at Rough which would depend on securing subsidies from the British government. Centrica was aiming to have some capacity available for the winter of 2022/23 against an overall plan to increase storage capacity gradually over time.
Note.
- Rough can store around 2832 million cubic metres of gas.
- This article on Energy Live News is entitled Reopening Of Rough Storage Gets The All-Clear.
Less well-known is SSE and Equinor’s Aldborough Gas Storage.
These three paragraphs from SSE web site, describe the gas storage.
The Aldbrough Gas Storage facility, in East Yorkshire, officially opened in June 2011. The last of the nine caverns entered commercial operation in November 2012.
The facility, which is a joint venture between SSE Thermal (66%) and Equinor, has the capacity to store around 330 million cubic metres (mcm) of gas.
SSE Thermal and Equinor have consent to increase the storage capacity at the Aldbrough site (Aldbrough Phase 2) and during the last couple of years have been working to involve the local community where appropriate to refine aspects of this project, which has not been progressed to date due to market conditions.
Future plans for the facility, may include converting it to one of the world’s largest hydrogen stores.
In the grand scheme of things, Rough and Aldborough, when you consider that the UK uses 211 million cubic metres of gas every day, will only keep us going for a few days.
But it should be noted, that the Easington gas terminal is connected to the Norwegian gas fields, by the Langeled pipeline.
So Yorkshire and Humberside will be alright.
Generating More Low-Cost Electricity
The only low-cost electricity of any size to come on stream will be wind-power.
This article on Renewables Now is entitled UK Hits 25.5 GW Of Wind Power Capacity.
These wind farms seem to be coming on stream soon or have been commissioned recently.
- Dogger Bank A – 1200 MW – Commissioning 2023 expected
- Dogger Bank B – 1200 MW – Commissioning 2024/25 expected
- Dogger Bank C – 1200 MW – Commissioning 2024/25 expected
- Hornsea Two – 1386 MW – Commissioned 2022
- Moray East – 950 MW – Commissioning 2022 expected
- Neart Na Gaoithe – 450 MW – Commissioning 2024 expected
- Seagreen – 1075 MW – Commissioning 2023 expected
- Triton Knoll – 857 MW – Commissioning 2022 expected
That is expected to be over 5 GW of offshore wind by the end of 2023.
In case there is some double counting, I’ll only say that wind power capacity could be near to 30 GW by December 2023, with perhaps another 3 GW by December 2024.
Other large wind farms in the future include.
- Berwick Bank – 4100 MW – Commissioning 2028 expected
- East Anglia Two – 900 MW – Commissioning 2026 expected
- East Anglia Three – 1400 MW – Commissioning 2027 expected
- Inch Cape Phase 1 – 1080 MW – Commissioning 2027 expected
- Hornsea Three – 2800 MW – Commissioning 2027 expected
- Moray West – 294 MW – Commissioning 2027 expected
- Morgan and Mona – 3000 MW – Commissioning for 2028 expected
- Morven – 2900 MW – Commissioning for 2028 expected
- Norfolk Boreas – 1400 MW – Commissioning 2027 expected
- Norfolk Vanguard – 1400 MW – Construction start planned for 2023
- Sofia – 1400 MW – Commissioning 2026 expected
That is over 14 GW of wind power.
I should also take note of solar and onshore wind power detailed in this document from the Department of Business, Industry and Industrial Strategy that lists all the Contracts for Difference Allocation Round 4 results for the supply of zero-carbon electricity.
It gives these figures and dates.
- Solar – 251 MW – Commissioning 2023/24 expected
- Solar – 1958 MW – Commissioning 2024/25 expected
- Onshore Wind – 888 MW – Commissioning 2024/25 expected
I can now build a yearly table of renewables likely to be commissioned in each year.
- 2022 – 3193 MW
- 2023 – 2275 MW
- 2024 – 701 MW
- 2025 – 5246 MW
- 2026 – 2300 MW
- 2027 – 6974 MW
- 2028 – 11400 MW
Note.
- Where a double date has been given, I’m taking the latter date.
- I have assumed that Norfolk Vanguard will be commissioned in 2028.
- I have ignored Hinckley Point C, which should add 3.26 GW in mid-2027.
- I have only taken into account one of the Scotwind wind farms in Scotland, some of which could be commissioned by 2028.
- I have assumed that BP’s Mona, Morgan and Morven will all be commissioned by 2028.
This is a total of 32 GW or an average of nearly 5 GW per year.
Increasing Electricity Storage
Big schemes like the 1.5 GW/ 30 GWh Coire Glas and 600 MW Cruachan 2 will help, but with 32 GW of renewable energy to be installed before 2028 and energy prices rocketing, we need substantial energy storage in the next couple of years.
One feasible plan that has been put forward is that of Highview Power’s CEO; Rupert Pearce,, that I wrote about in Highview Power’s Plan To Add Energy Storage To The UK Power Network.
The 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.
Note.
- The first 30 GWh CRYOBattery is planned to be operational by late 2024.
- 600 GWh distributed around the country would probably be sufficient.
I believe that as these batteries are made from standard proven components, they could be built fairly quickly.
Paying For The Energy Storage
This press release from Highview Power is entitled New Analysis Reveals Extent Of UK Renewable Energy Waste, which makes these three bullet points.
- Enough renewable energy to power 500,000 homes a day wasted since the energy crisis began.
- 8 out of 10 Britons want more investment in boosting Britain’s energy resilience.
- UK spent £390 million turning off wind farms and using gas since September 2021.
Note.
- As the press release was published in July 2022, was the £390 million for ten months.
- Will this level of spend continue, as we’re not creating any electricity storage or building any factories that will start in a year or so, that will need large amounts of electricity?
- The Germans are at least building the NeuConnect interconnector between the Isle of Grain and Wilhelmshaven.
- As we’re adding up to 5 GW per year to our renewable energy systems, this problem will surely get worse and we’ll spend more money switching off wind turbines.
We have the money to build a very large amount of energy storage.
Improving The Control Algorithm
A better control algorithm would always help and politicians should only be allowed to set objectives.
Conclusion
There is a chance we’ll have an oversupply of electricity, but this will have effects in the UK.
- Gas-fired power-stations will be retired from front-line service to produce electricity.
- Some will question the need for nuclear power.
- Gas may even be used selectively to provide carbon dioxide for agricultural, scientific and industrial processes.
- Industries that need a lot of electricity may build factories in the UK.
- We will have a large supply of green hydrogen.
But it should bring the price of electricity down.
Energy Storage Will Deliver ‘Tens Of Billions Of Pounds A Year’
The title of this post, is the same as that of this article on Energy Live News.
This is the first paragraph.
This week’s Net Hero Podcast delves into how energy storage is being underappreciated as a key to cutting costs on our energy bills.
I have listened to the half-hour podcast and it is a fascinating interview with Rupert Pearce, who is the CEO of Highview Power.
He talks about.
- Green stability services
- Power stations in a box
- Vehicle-to-grid storage
- How Highview Power is location agnostic.
