Can Highview Power’s CRYOBattery Compete With Pumped Storage Hydroelectricity?
In this article on the Telegraph, Rupert Pearce, who is Highview’s chief executive and ex-head of the satellite company Inmarsat, discloses this.
Highview is well beyond the pilot phase and is developing its first large UK plant in Humberside, today Britain’s top hub for North Sea wind. It will offer 2.5GW for over 12 hours, or 0.5GW for over 60 hours, and so forth, and should be up and running by late 2024.
The Humberside plant is new to me, as it has not been previously announced by Highview Power.
- If it is built it will be megahuge with a storage capacity of 30 GWh and a maximum output of 2.5 GW.
- Humberside with its connections to North Sea Wind, will be an ideal location for a huge CRYOBattery.
- The world’s largest pumped storage hydroelectric power station is Fengning Pumped Storage Power Station in China and it is 40 GWh.
Pumped storage hydroelectric power stations are the gold standard of energy storage.
In the UK we have four pumped storage hydroelectric power stations.
- Cruachan Power Station – 7.1 GWh
- Dinorwig Power Station (Electric Mountain) – 9.1 GWh
- Falls of Foyers – 10 GWh
- Ffestiniog Power Station 1 GWh
With two more under construction.
- Coire Glas Power Station – 30 GWh
- Red John Power Station – 2.8 GWh
As energy is agnostic, 30 GWh of pumped storage hydroelectric power at Coire Glas is the equivalent of 30 GWh in Highview Power’s proposed Humberside CRYOBattery.
Advantages Of CRYOBatteries Over Pumped Storage Hydroelectric Power
I can think of these advantages.
- Cost
- Could be build on the flat lands of East Anglia or Lincolnshire
- Factory-built
- NIMBYs won’t have much to argue about
- No dams
- No flooding of valleys
- No massive construction sites.
- No mountains required
- No tunnels
- Small footprint
I suspect that a large CRYOBattery could be built well within a year of starting construction.
Rupert Pearce’s Dream
The Telegraph article says this and I suspect it’s a quote from Rupert Pearce.
Further projects will be built at a breakneck speed of two to three a year during the 2020s, with a target of 20 sites able to provide almost 6GW of back-up electricity for four days at a time, or whatever time/power mix is optimal.
6 GW for four days is 576 GWh, which if it were spread around twenty sites is 28.8 GWh per site, which is just under the 30 GWh of the proposed Humberside CRYOBattery.
Conclusion
You can just imagine the headlines in The Sun!
Man In Bishop’s Stortford Shed Saves The World!
This story on the BBC, which is entitled Meet The British Inventor Who Came Up With A Green Way Of Generating Electricity From Air – In His Shed, explains my suggested headline.
Now that’s what I call success!
How Will Highview Power Affect The Lithium-Ion Grid Battery Market?
In this article on the Telegraph, Rupert Pearce, who is Highview’s chief executive and ex-head of the satellite company Inmarsat, discloses this.
Highview is well beyond the pilot phase and is developing its first large UK plant in Humberside, today Britain’s top hub for North Sea wind. It will offer 2.5GW for over 12 hours, or 0.5GW for over 60 hours, and so forth, and should be up and running by late 2024.
The Humberside plant is new to me, as it has not been previously announced by Highview Power.
- If it is built it will be megahuge with a storage capacity of 30 GWh and a maximum output of 2.5 GW.
- Humberside with its connections to North Sea Wind, will be an ideal location for a huge CRYOBattery.
- The world’s largest battery is at Ouarzazate Solar Power Station in Morocco and it is 3 GWh.
- The world’s largest pumped storage power station is Fengning Pumped Storage Power Station in China and it is 40 GWh.
The proposed Humberside battery also has a smaller sibling under construction at Carrington in Manchester.
This will have a storage capacity of 250 MWh and a maximum output of 50 MW.
Factors Affecting The Choice
Several factors will affect the choice between lithium-ion batteries and Highview Power’s CRYOBattery.
Reliability
Reliability is paramount and whilst lithium-ion batteries batteries have a high level of reliability, there probably needs to be more development and quality assurance before CRYOBatteries have a similar level of reliability.
Size
The largest lithium-ion battery, that has been proposed in the UK, is the 320 MW/640 MWh battery that will be installed at the Gateway Energy Centre in Essex.
This size of CRYOBattery should be possible, but this size is probably in range of both lithium-ion and CRYOBatteries.
Safety
The Wikipedia entry for Battery Storage Power Station has this to say about Safety.
Some batteries operating at high temperatures (sodium–sulfur battery) or using corrosive components are subject to calendar ageing, or failure even if not used. Other technologies suffer from cycle ageing, or deterioration caused by charge-discharge cycles. This deterioration is generally higher at high charging rates. These two types of ageing cause a loss of performance (capacity or voltage decrease), overheating, and may eventually lead to critical failure (electrolyte leaks, fire, explosion).
An example of the latter was a Tesla Megapack in Geelong which caught fire, fire and subsequent explosion of battery farm in Arizona, fire of Moss Landing battery farm. Concerns about possible fire and explosion of a battery module were also raised during residential protests against Cleve Hill solar farm in United Kingdom. Battery fire in Illinois resulted in “thousands of residents” being evacuated, and there were 23 battery farm fires in South Korea over the period of two years. Battery fires may release a number of dangerous gases, including highly corrosive and toxic hydrogen fluoride.
The long term safety of a CRYOBattery is probably not yet known in detail, but I suspect in some applications, CRYOBatteries could be safer than chemical batteries.
Environmental Factors
I suspect that CRYOBatteries can be built without any hard-to-mine or environmentally-unfriendly materials like lithium.
Cost
The article in The Telegraph, says this about costs.
Mr Pearce said Highview’s levelised cost of energy (LCOE) would start at $140-$150, below lithium, and then slide on a “glide path” to $100 with over time.
It does look that the all important factor of cost could be the clincher in the choice between the two systems.
For larger batteries, the CRYOBattery will probably have a larger advantage.
Conclusion
I can see Highview Power and their CRYOBatteries putting up a good fight against lithium-ion batteries, especially with larger batteries, where they have a larger cost advantage.
In the UK, we will know they have won an advantage, if the two big battery-storage funds; Gore Street and Gresham House, start to install CRYOBatteries.
Britain Will Soon Have A Glut Of Cheap Power, And World-Leading Batteries To Store It
The title of this post, is the same as that of this article on the Telegraph.
This is the first four paragraphs.
Today’s electricity price shock is the last crisis of the old order. Britain will soon have far more power at times of peak production than it can absorb. The logistical headache will be abundance.
Wind and solar provided almost 60pc of the UK’s power for substantial stretches last weekend, briefly peaking at 66pc. This is not to make a propaganda point about green energy, although this home-made power is self-evidently displacing liquefied natural gas (LNG) imported right now at nosebleed prices.
It is a point about the mathematical implications of the UK’s gargantuan push for renewables. Offshore wind capacity is going to increase from 11 to 50 gigawatts (GW) by 2030 under the Government’s latest fast-track plans.
RenewableUK says this country currently has a total of 86GW in the project pipeline. This the most ambitious rollout of offshore wind in the world, ahead of China at 78GW, and the US at 48GW.
The article goes on to give a comprehensive account of where we are with renewables, where we are going and how we will handle things, when the wind doesn’t blow.
Dogger Bank
The article says this about the Dogger Bank wind farm, which is being developed by SSE.
The giant hi-tech turbines to be erected on the Dogger Bank, where wind conditions are superb, bear no resemblance to the low-tech, low-yield dwarves of yesteryear. The “capacity factor” is approaching 60pc, which entirely changes the energy equation.
A capacity factor of 60 % seems a bit high to me and is what can be expected with the latest floating turbines. But these are fixed to the sea floor.
The Wikipedia entry for the Dogger Bank wind farm, says this about the building of the the first two sections of the massive wind farm.
On 21 September 2020, it was announced that Dogger Bank A and B will use 190 GE Haliade-X 13 MW offshore wind turbines over both sites, meaning that 95 turbines will be used on each site.[19] The availability of upgraded Haliade-X turbines rated at 13 MW rather than 12 MW means that each site will be capable of generating up to 1.235 GW, for a total of 2.47 GW. Turbines will be pre-assembled at Able Seaton Port in Hartlepool, an activity that will lead to the creation of 120 skilled jobs at the port during construction. Turbine installation is expected to commence in 2023 at Dogger Bank A.[20] Power Purchase Agreements (PPA) for 15 years were signed in November 2020. Offshore cable laying started in April 2022. Installation of the turbine foundations was started in July 2022.
This GE data sheet about the Haliade-X offshore wind turbine, says this about capacity factor.
it also features a 60-64% capacity factor above industry standard. Capacity factor compares how much energy was generated against the maximum that could have been produced at continuous full power operation during a specific period of time.
A 60-64% capacity factor is exceptional.
Current plans for Dogger Bank indicate that 3.6 GW will be installed and operational by 2024/25.
Could that mean that Dogger Bank will be able to deliver 2.16 GW almost continuously, on GE’s figures? Sizewell B is only 1.25 GW.
Sofia Wind Farm
There was going to be a fourth section to Dogger Bank, but this is now the separate Sofia wind farm.
- It is being developed by RWE.
- The first phase of three has a capacity of 1.4 MW. Does that mean Sofia will eventually be a 4.2 GW wind farm?
- RWE seem to be putting in a very large offshore substation. Could this support a lot more turbines?
- The wind farm seems to be using high-specification SiemensGamesa 14MW SG 14-222 DD wind turbines, which have a Power Boost facility to deliver up to 15 MW.
- I can’t find anything about capacity factor.
Wikipedia gives a delivery date of 2023 for the first phase of Sofia.
Storing Electricity
The article says this about storing electricity.
Much of the power will have to be stored for days or weeks at a time. Lithium batteries cannot do the job: their sweet spot is two hours, and they are expensive. You need “long duration” storage at a cost that must ultimately fall below $100 (£82) per megawatt hour (MWh), the global benchmark of commercial viability.
That is now in sight, and one of the world leaders is a British start-up. Highview Power has refined a beautifully simple technology using liquid air stored in insulated steel towers at low pressure.
I have had Highview Power on my radar for some time.
Highview Power
What is there not to like about Highview Power?
- The original idea was developed in a shed in Bishop’s Stortford, by a lone inventor.
- Sumitomo are one of their backers.
- They are also backed by English Universities and the UK Government.
- They have run a successful pilot plant in Bury.
- They are now building their first full-size 50 MW/250 MWh commercial plant at Carrington near Manchester.
- Much of the equipment they use to build their batteries is standard equipment from world-class companies like MAN.
- There are no exotic and expensive materials used.
The writer of the article has obviously had a long chat with Rupert Pearce, who is Highview’s chief executive and ex-head of the satellite company Inmarsat.
Pearce happily discloses this monster.
Highview is well beyond the pilot phase and is developing its first large UK plant in Humberside, today Britain’s top hub for North Sea wind. It will offer 2.5GW for over 12 hours, or 0.5GW for over 60 hours, and so forth, and should be up and running by late 2024.
Note.
- The world’s largest battery is at Ouarzazate Solar Power Station in Morocco and it is 3 GWh.
- Highview’s Humberside battery is megahuge at 30 GWh.
- The world’s largest pumped storage power station is Fengning Pumped Storage Power Station in China and it is 40 GWh.
- My experience of doing the calculations for large reaction vessels and other structures, tells me, that Highview should be able to construct huge systems.
I suspect that it will be easier and more affordable to build the Humberside battery.
This is another pair of paragraphs.
Mr Pearce said Highview’s levelised cost of energy (LCOE) would start at $140-$150, below lithium, and then slide on a “glide path” to $100 with over time. The company has parallel projects in Spain and Australia but Britain is the showroom.
“The UK is a fantastic place to do this. It has one of the most innovative grids in the world and an open, fair, liquid, market mechanism with absolute visibility,” he said.
It looks to me, that Rupert Pearce has taken Highview Power to a different level, in his short tenure at the company.
The world will soon be very familiar with the name of Highview Power.
SolarDuck & RWE Will Build A Floating Solar Park In The North Sea
The title of this post, is the same as that of this article on CleanTechnica.
This is the sub-title.
SolarDuck and RWE will work together on an offshore floating solar project in the North Sea that will include battery storage.
These two paragraphs explain the concept.
Offshore wind is poised to provide a significant proportion of Europe’s electrical energy in the near future. But those towers and turbines have to be spaced fairly far apart to avoid interfering with each other. That leaves a lot of open ocean in between them, ocean that has sunlight falling on it all day long.
SolarDuck, a Dutch/Norwegian company, is working on floating solar technology that would float on the surface of the ocean to generate electricity to supplement the output from those offshore wind turbines. They already need to have undersea cables to carry their electricity ashore. Why not leverage that infrastructure to carry electricity from solar panels as well?
I would only worry about the economics.
I very much feel that the structures can be robust enough, given the wealth of experience with offshore oil and gas platforms and the experience in World War 2 with Lily and Clover.
The EuroAfrica Interconnector
The Wikipedia entry for the EuroAfrica Interconnector, introduces the project like this.
EuroAfrica Interconnector is a HVDC interconnector and submarine power cable between the Greek, Cypriot, and Egypt power grids.
The Wikipedia entry has a section called Technical Data, where this is said.
The EuroAfrica Interconnector will link Egypt with the Cypriot and Greek power grids through the island of Crete, with a high-voltage direct current submarine power cable of length around 1,396-kilometre (867 mi). Egypt will be connected with Cyprus with a 498-kilometre (309 mi) long cable. Cyprus will be connected with Crete with a 898-kilometre (558 mi) long cable providing a connection to the pan-European electricity grid.[1] The laying depth of cable will be up to 3,000 metres (9,800 ft) under sea level in some areas between Crete and Cyprus. It will have a capacity to transmit 2,000 megawatts of electricity in either direction. Annual transmission capacity is 17.5 TWh, much more than the annual production of the Aswan Dam.
In The EuroAsia Interconnector, I noted how Israel will be connected to Cyprus, thus when both interconnectors are complete, Cyprus, Egypt, Greece and Israel will be able to share electricity.
The EuroAsia Interconnector
The Wikipedia entry for the EuroAsia Interconnector, introduces the project like this.
The EuroAsia Interconnector is a proposed HVDC interconnector between the Greek, Cypriot, and Israeli power grids via the world’s longest submarine power cable (310 kilometres (190 mi) from Israel to Cyprus and 898 kilometres (558 mi) from Cyprus to Greece, for a total of 1,208 kilometres (751 mi)). Connecting Kofinou, Cyprus to Hadera, Israel and Korakias, Crete, Greece and stated to finish construction in 2023.
When completed it will have a capacity of 2 GW.
From Wikipedia, it appears that at least initially, Israel will export electricity produced in gas-fired power stations from their own more than adequate supplies of natural gas.
In Andrew Forrest’s Fortescue Future Industries Inks Deal With Kingdom of Jordan For Green Hydrogen Study, I published this Google Map of Jordan.
Surely, in the future, the EuroAsia interconnector could be carrying solar generated green electricity from Iraq, Jordan and Saudi Arabia to Cyprus and Greece.
As, according to Reuters, Greece covers about 40% of its annual energy needs with Russian gas, this can’t be good for Vlad the Mad and his bloodstained gas.
Will We See More Multi-Country Renewable Energy Deals?
In this blog, I have talked about various deals, where two or more countries and/or companies are getting together to generate electricity in one country and transfer it to another, either as electricity or as hydrogen
Examples include.
- The Asian Renewable Energy Hub, which I first wrote about in Vast Australian Renewable Energy Site Powers BP’s Ambitions.
- The Australia-Asia PowerLink, which I first wrote about in Sun Cable’s Australia-Asia PowerLink.
- Fortescue Future Industries will convert cattle stations in Western Australia into renewable power stations.
- The EuroAfrica Interconnector is a HVDC interconnector and submarine power cable between the Greek, Cypriot, and Egypt power grids, which I first wrote about in The EuroAfrica Interconnector.
- The EuroAsia Interconnector is a proposed HVDC interconnector between the Greek, Cypriot, and Israeli power grids via the world’s longest submarine power cable, which I first wrote about in The EuroAsia Interconnector.
- Icelink is a proposed electricity interconnector between Iceland and Great Britain, which I first wrote about in Is Iceland Part Of The Solution To The Problem Of Russia?
- The Morocco-UK Power Project, which I first wrote about in Moroccan Solar-Plus-Wind To Be Linked To GB In ‘Ground-Breaking’ Xlinks Project.
- Namibian Green Hydrogen, which I first wrote about in Namibia Is Building A Reputation For The Cheapest Green Hydrogen.
There are also all the hydrogen deals done by Fortescue Future Industries.
Where Are There Possibilities Of More Multi-Country Renewable Energy Deals?
These are a few serious possibilities.
Argentina
This is an extract from this page on Wind Energy International, which is entitled Argentina.
Argentina has an estimated technical wind energy potential of 300 GW. In southern Patagonia (Chubut and Santa Cruz provinces), average wind speeds range between 9.0 and 11.2 m/s, whereas in the north (Neuquén and Río Negro provinces), wind speeds range from 7.2 to 8.4 m/s. The general average capacity factor for Argentina is 35% and in the Patagonia region it ranges between as much as 47% and 59%. Especially in Northwest Patagonia, locally known as the Comahue region, hydro and wind may seasonally complement each other and.benefit both technologies. One other promising region for wind power development is the Atlantic sea coast.
As I wrote in Australia’s FFI Plans $8.4 Billion Green Hydrogen Project In Argentina, it appears that Andrew Forrest and FFI are already on the ground.
Australia
There are already three major schemes based on Australia and I am certain they will be more. Especially, as Japan, Korea, Malaysia and Singapore will need the zero-carbon energy.
It would appear that except for the Australia-Asia PowerLink, the energy will be transferred as liquid hydrogen or liquid ammonia.
Bangladesh
Bangladesh wouldn’t be on the lists of many, where ideal countries for renewable energy are being discussed.
But, this report on Energy Tracker Asia is entitled The Renewable Energy Potential of Bangladesh, where this is said.
A report investigating the renewable energy technical capacity of Bangladesh found that the country could deploy up to 156 GW of utility-scale solar on 6,250 km2 of land and 150 GW of wind. Offshore wind power would account for 134 GW of this total capacity.
I wouldn’t be surprised to see Bangladesh, supplying renewable energy to the East, with international companies and organisations developing the renewable infrastructure.
I think it should be noted that international companies flock to countries, where the investment opportunities are good. That has happened in the UK, with offshore wind, where many wind farms have been developed by companies such as Equinor, Iberola, RWE and Wattenfall.
Chile
Chile has started to develop the 100,000 square kilometres of the Atacama Desert for solar power and I wrote about this in The Power Of Solar With A Large Battery.
This sentence in the Wikipedia entry for Energy In Chile, illustrates the potential of solar power in the Atacama Desert.
In 2013, Total S.A. announced the world’s largest unsubsidised solar farm would be installed with assistance from SunPower Corp into Chile’s Atacama desert.
I also wrote Chile Wants To Export Solar Energy To Asia Via 15,000km Submarine Cable, about Chile’s ambitions to supply Asia with energy.
Ethiopia
Andrew Forrest of Fortescue Future Industries is on the case, as I wrote in Fortescue Future Industries Enters Ethiopia to Produce Green Energy.
North Africa
Consider.
- The major North African countries of Morocco, Algeria, Tunisia, Libya and Egypt, all have and depend on to a certain extent on fossil fuels.
- There are gas pipelines to Spain and Italy.
- Morocco will be the Southern end of the Morocco-UK Power Project, if it gets developed.
- All five countries have some nuclear power stations.
- All five countries have lots of sun for solar power.
- Some Saharan countries to the South of Morocco, Algeria and Libya could also provide energy from the sun.
- Egypt has substantial hydro-electric power on the River Nile.
- Egypt will be connected to Greece through the EuroAfrica Interconnector.
I believe that a well-designed and co-ordinated project could generate a lot of electricity and hydrogen for Europe and bring much-needed income and employment to North Africa.
I feel that if the Morocco-UK Power Project can be successfully built, then this could create a flurry of activity all over North Africa.
Saudi Arabia
Saudi Arabia has a problem. As the rest of the world moves away from fossil fuels in the next few decades, they will see the revenues from oil and natural gas come under pressure.
But as a rich country, with 2.15 million km² of land and lots of sun, they must have some potential to generate solar electricity.
In the Wikipedia entry for Solar Power In Saudi Arabia, this is said.
The Saudi agency in charge of developing the nations renewable energy sector, Ka-care, announced in May 2012 that the nation would install 41 gigawatts (GW) of solar capacity by 2032.[2] It was projected to be composed of 25 GW of solar thermal, and 16 GW of photovoltaics. At the time of this announcement, Saudi Arabia had only 0.003 gigawatts of installed solar energy capacity. A total of 24 GW of renewable energy was expected by 2020, and 54 GW by 2032.
Wikipedia also says that Saudi Arabia also has nuclear ambitions.
I can see that Saudi Arabia will replace some of their oil and gas exports with green hydrogen.
Green Hydrogen Namibia
The title of this post, is the same as that of this web site.
This is the mission statement on the home page.
With its abundant, world-class renewable energy resources and increasing demand for green hydrogen worldwide, Namibia is quickly emerging as an early entrant in this new market and has ambitions of becoming the leading exporter of Green Hydrogen in Africa.
Namibia is serious about green hydrogen.
Rolls-Royce Chief Warren East Spies Rebound For Air Travel
The title of this post, is the same as that of this article on The Times.
It is a must-read article.
This is the first paragraph.
Warren East, the outgoing chief executive of Rolls-Royce, has sounded a bullish note on aviation’s recovery from Covid-19, reporting increased demand from the jet-engine maker’s airline customers and expressing his belief that China will gradually open up to international travel.
Certainly, with all the chaos at the Channel this weekend, people are starting to travel again.
Support For The Military
This is a paragraph in the article.
Tom Bell, head of Rolls-Royce Defence, said the company was in talks with the US and UK militaries about supplying “deployable” reactors for military bases.
I’m sure that a reactor would have advantages to a large diesel or gas-turbine generator to power a military base.
- Military bases need a lot of power.
- It would not need refuelling every day.
- It could be connected to an electrolyser, to generate hydrogen for vehicles.
- It would be a lot quieter.
- I wonder, if it could be transported in a large transport aircraft.
But I feel, it might have other applications.
- It could provide power support after a large earthquake or natural disaster.
- It could provide power in remote or difficult locations.
- If the only power station for a remote community had a catastrophic failure, a deployable reactor could be brought in.
- It could provide power for a large construction site, which would help to decarbonise the construction.
- Power would be zero-carbon at point of generation.
The reactors might even be rail-transportable, so they could be moved to where they are needed safely and quickly.
But I don’t think they would necessarily be the same size as the Rolls-Royce SMRs, which are 470 MW.
A Scalable Reactor
This is a paragraph in the article.
Rolls also has a contract with the UK Space Agency to develop a “micro reactor” for space vehicles and satellites, Bell added. “These are really exciting opportunities for us to not only perpetuate our business undersea, at sea, on land, in the air, but also to go to space,” he said. East noted the advantage of nuclear reactors in space: “You can’t have air-breathing engines on the moon.”
Note.
- East is Warren East, who is the outgoing Chief Executive of Rolls-Royce.
- Nuclear power sources have been used in space before, usually by using an isotope, that gives out heat, as it decays.
- How small is micro?
- The US deployed a 1.75 MW nuclear power plant in Antarctica under the Army Nuclear Power Program. That reactor also provided heating and hot water. It is worth reading the Wikipedia entry, especially the section about the MM-1 reactor.
It does seem that Rolls-Royce are designing a reactor that can be scaled in size, to cover a whole spectrum of applications.
UK-German Energy Link Reaches Financial Close
The title of this post, is the same as that of this article on renews.biz.
These are the three introductory paragraphs.
A multibillion-euro 725 km interconnector between the UK and Germany has reached financial close, paving the way for construction works to begin in the coming months.
The £2.4bn (€2.8bn) NeuConnect interconnector will form an “invisible energy highway” with subsea cables allowing up to 1.4GW of electricity to flow in either direction between the UK and Germany and will help deliver a more secure and resilient energy supply, particularly as more renewable generation is added.
Independent analysis shows the project will create over £1.7bn in UK consumer benefits over 25 years.
Other points about NeuConnect include.
- It has been privately funded by a consortium of over twenty national and international banks.
- It will run between the Isle of Grain and a the new Fedderwarden substation in Wilhelmshaven.
- It should be operational in 2028.
Although, it is bi-directional, it appears that one of its major uses will be to provide Germany with UK wind energy to compensate for the loss of Putin’s bloodstained gas.
