All You Want To Know About Highview Power
This article on Power is entitled Market Prospects Heating Up for Cryogenic Energy Storage.
It talks in detail about the technology, financing and market prospects for Highview Power and their CRYOBattery.
- Their batteries store energy by liquifying air and storing it in large tanks.
- To recover the energy, the air is encouraged to go to a gaseous phase and put through an air turbine.
- Their first commercial system is being built at Carrington near Manchester.
- The Carrington system will have an output of 50 MW and be able to store up to 250 MWh.
- Other systems are under development for Vermont and Spain.
- The systems are built like Leho from readily available components from the oil and gas industry.
One of my regrets in life, is that I missed the crowdfunding for this company!
Read the article as you might find one of Highview Power’s CRYOBatteries coming to a site near you.
Power’s article is the best yet on describing the technology.
How Siemens Gamesa Could Give Coal Plants a Second Life
This article on Greentech Media is a must-read as it makes you think. This is the sub-title.
The ETES thermal battery can offer coal plants a new life as heat and power storage hubs. The first customer for a full-size version could be on-board as early as next year.
It talks about the philosophy of reusing coal-fired power station sites and some of their equipment like turbines.
It is an idea much more applicable to countries like the US and Germany rather than the UK, as they still have lots of operational coal-fired power stations and and we only have a few.
I first came across this idea, when Highview Power were talking about their 50/MW/400 MWh installation in Vermont, which was to be built on the site of a demolished coal-fired power station. The utility company and Highview were in that case just reusing the grid connection.
But then I’ve heard of other energy storage systems using old power station sites.
And not to forget that Highview Power’s installation at Carrington is close to a gas-fired power station.
Highview Power Unveils $1bn Of Liquid-Air Energy Storage Projects In Spain
The title of this post, is the same as that of this article on Recharge Magazine.
The article is based on this press release from Highview Power, which is entitled Highview Power Developing 2 GWh of Liquid Air Long Duration Energy Storage Projects in Spain.
This is the introductory paragraph from the press release.
Highview Power, a global leader in long duration energy storage solutions, announced today it is developing up to 2 GWh of long duration, liquid air energy storage projects across Spain for an estimated investment of around $1 billion. These projects will enable several Spanish regions to move towards their net zero emissions target.
The press release also says this about location and size.
Highview Power is planning to develop up to seven CRYOBattery™ projects ranging from 50 MW/300 MWh in Asturias, Cantabria, Castilla y Leon, and the Canary Islands.
Three of these areas are in Northern Spain and the other is a group of islands.
As Spain has at least two large pumped storage systems, perhaps geography rules this proven technology out in these areas.
System Modularity
According to the Wikipedia entry for Highview Power, the two current CRYOBatteries under development are sized as follows.
- Carrington, Manchester, UK – 50 MW/250 MWh – Under construction
- Vermont, USA – 50 MW/400 MWh – Under development
Do the figures indicate that several systems will share the same 50 MW core power system, with a number of liquid air tanks to give the appropriate capacity?
I have extensively modelled chemical plants in my past to see, how different sizes work and I am fairly certain, that Highview Power have developed a design, that is extremely flexible.
It looks like if initial calculations show that a system capable of supplying 50 MW for five hours is needed, but operation proves that a capacity of six hours would be better, that all Highview Power need to do is add another 50 MWh tank.
This is surely an operator’s dream, as if say a developer builds a thousand dwellings and/or a windfarm nearby and more energy storage is needed, an appropriate number of extra tanks can be added.
Sourcing The 50 MW Core Power System
I talked about how the first system at Carrington will use a system from MAN Energy Solutions in MAN Energy Partners With Highview Power On Liquid-Air Energy-Storage Project.
This surely is an approach that minimises risk.
Sourcing The Storage Tanks
I have been searching the Internet for manufacturers of cryogenic gas tanks and I’ve found them in countries like Australia, Brazil, Germany, India, South Africa, Spain, the UK and the US.
But then most hospitals have one for their liquid oxygen.

They are not difficult to find.
Spain And Renewable Energy
Spain is a large producer of renewable energy and also a leader in wind and solar power technology.
See Renewable Energy in Spain on Wikipedia for more details.
Siemens Gamesa, which was created by a merger of a German and a Spanish company and is headquartered at Zamudio in Spain, have also developed the Siemens Gamesa ETES, which is a volcanic rock-based energy storage system about the same size of Highview Power’s CRYOBattery.
Conclusion
It looks to me, that Highview Power have closed a good sale.
Albannach Island: Multi-Million Pound Green Energy Plans Would Create 300 Construction Jobs
The title of this post, is the same as that of this article on the Aberdeen Press and Journal.
This is the introductory paragraphs.
A multi-million pound green energy power venture – called Albannach Island – would give a much-needed jobs boost to Caithness.
Highview Power is behind the plans to build a liquid air energy storage plant in a disused part of a quarry in Spittal, adjoining the most northerly stretch of the A9.
The plant appears to be a 50MW/250 MWh CRYOBattery, that is probably similar in size to the one currently being built by Highview Power at Carrington, near Manchester.
This Google map of the North-East corner of Scotland, shows the location.
Note.
- John O’Groats is in the North-East corner of the map.
- The red arrow shows the location of the A & D Sutherland quarry, where the Highview Power’s CRYOBattery will be located.
This second Google map shows the location in more detail.
Note.
- The A & D Sutherland quarry is in the South-East corner of the map.
- The CRYOBattery will use five acres at the North of the quarry site.
- In the North-West corner of the map is the Spittal sub-station.
The Spital sub-station is described like this on the Scottish and Southern Electricity Networks web site.
Spittal is a new electricity convertor station and is part of the £1.1bn Caithness-Moray project which represents the largest investment in the north of Scotland’s electricity network since the hydro development era of the 1950s and is the largest capital investment project undertaken by the SSE Group to date. It is also the largest Living Wage contract ever awarded in the UK, demonstrating SSEN’s strong commitment to ensure all employees working on its sites get a fair day’s pay for a fair day’s work.
It looks like the CRYOBattery will be the cherry on top of the very billion pound cake of the Caithness-Moray Link.
Conclusion
We’ll be seeing more battery installations like this to stabilise power.
Nothing is said in the article, about who is paying for the battery. The only clue is it talks about Highview as a London-based conglomerate.
I wonder, if the company has formed a partnership with one of the energy trusts or a battery site developer.
Bring Africa Out Of The Dark
The title of this post, is the same as that of this article on the Zimbabwean.
The article has been written by Humphrey Kariuki, who is a Kenyan businessman, who is on a mission to bring electricity to Africa.
He has teamed up with Highview Power to do it using batteries.
Read the article.
Alternative Energy Storage Technologies To Challenge Electrochemistry
The title of this post, is the same as that of this article on Battery and Energy Storage Magazine.
It gives a good summary of two energy storage system; Highview Power and Gravitricity, that I rate highly promising.
It also gives details of a Danish system called Stiesdal Storage Technologies, which is developing a hot rocks energy storage system.
The article says this about the system.
The pumped-heat ESS uses pea-sized crushed basalt, rock in insulated steel tanks with the stored energy released by turbine.
SST CEO Peder Riis Nickelsen said: “The cost of crushed stone is at a totally different level per unit of energy than practically any other material for energy storage. Our charging and discharging system can utilise well-known technologies that have been applied for a century within other industries and are well-suited for mass production.”
The cost of materials is estimated to be €10 ($12) per kWh.
The first demonstration project, a 1-2MW, 24h capacity unit, will be installed at a power plant in Denmark next year, and will operate commercially.
This page on the Striesdal web site, explains the technology.
It sounds like the system uses very similar principles to Siemens Gamesa ETES, with a different heat storage medium.
Conclusion
At my last count, there now appears to be upwards of half-a-dozen viable alternatives to chemical batteries and traditional pumped storage. Some of the technologies are also backed, by large companies, organisations and countries, who can afford to take a long-term view.
I hope those, who claim that renewables will never power the world, have at least got the recipe for the cooking of humble pie ready.
Form Energy Discloses A Small Amount
Form Energy has been a bit mysterious, but this article on Energy Storage News, which is entitled Renewables As Baseload Energy: Form Energy’s Multi-Day |Storage Seeks To Replace Gas And Coal.
Form Energy certainly have large ambitions, backing from organisations like Bill Gates’ Breakthrough Energy Ventures and an order for a 1 MW/150 MWh pilot for Great River Energy in Minnesota, and I suspect this is probably enough to ensure success in the mid-size market sector, which they share with the UK’s Highview Power, who are building their first grid-scale 50 MW/ 250 MWh at Carrington to the South of Manchester.
The article is certainly an interesting insight into one of the new energy storage ventures.
MAN Energy Partners With Highview Power On Liquid-Air Energy-Storage Project
The title of this post, is the same as that of this article on Renewable Energy Magazine.
This is the introductory paragraph.
Highview Power, a leader in long duration energy storage solutions, has selected MAN Energy Solutions to provide its LAES turbomachinery solution to Highview Power for its CRYOBattery™ facility, a 50 MW liquid-air, energy-storage facility – with a minimum of 250MWh – located in Carrington Village, Greater Manchester , U.K.
The article is almost a word-for-word copy of this press release from MAN Energy Solutions, which has a similar title to this post and the Renewable Energy Magazine article.
As an Electrical Engineer who has done a lot of work in Project Management, I find these two paragraphs significant.
Construction will proceed in two phases. Phase 1 will involve the installation of a ‘stability island’, to provide near-instantaneous energy grid stabilisation. This will be achieved using a generator and flywheel, among other components. Enabling short-term stabilisation will provide the basis for Phase 2 and the completion of the more complex liquid air energy storage system that includes various compressors, air expanders and cryogenic equipment.
Phase 2 will represent the integration of stability services with a full-scale long-duration energy storage system, and in doing so promote the full integration of renewable energy. The Carrington project will offer a blueprint for future projects and cement the partnership between MAN Energy Solutions and Highview Power.
I first became acquainted with the use of flywheels to stabilise energy, when I was working in Enfield Rolling Mills as a vacation job at sixteen.
The centerpiece of their factory was a rolling mill, which took heated copper wirebars about two metres long amd ten centimetres square and rolled them into thick copper wire just a few millimetres in diameter. The mill was driven by a powerful electric motor, to which it was connected with a 97 tonne flywheel perhaps four metres in diameter in between. The flywheel spun at probably 3000 revolutions per minute.
The wirebar used to meander through the rolling mill several times and at each turn, the head would be caught by a man with a pair of tongs and turned back through the mill.
Each time the wire-bar went through a new pair of rolls the energy needed increased, as there was more rolling to do. So this extra energy was taken from the flywheel!
The rolling mill incidentally had been built by Krupp before the First World War. It still had the Krupp trademark of three interlocked railway tyres all over it. It had ended up in Enfield as reparations after the First World War. Enfield Rolling Mills added a fourth ring to create their own trademark.
It would appear that the kinetic energy of that flywheel could be as high as 1.6 MWh. Flywheels also react very fast.
Flywheel energy storage would appear to be a feasible intermediate energy store for this type of application.
I always remember Shimatovitch, who was the Chief Engineer of the company had jokingly once said that if the flywheel came off its bearings, it would have ended up a couple of miles away and would have demolished all the houses in its path. But he was a man with a dark sense of humour, who had spent most of the Second World War in a Nazi concentration camp.
Could it be that Phase 1 is the installation of a similar system to that I saw working in the 1960s, but upgraded with modern electronics, which exchanges power with the grid to create the stability island referred to in the press release.
In Phase 2 electricity can be passed to and from the CRYOBattery.
Looking at the MAN Energy Solutions web site, I suspect that they don’t care what sort of energy store they connect to the grid.
They would appear to be an excellent choice of engineering partner for Highview Power.
I also wonder how many other applications and customers, they will bring into the partnership.
Conclusion
This looks like a very sensible and low-risk strategy to connect the CRYOBattery to the grid.
Highview Power Introduces Revolutionary Cryogenic Energy Storage Technology To The African Market
The title of this post, is the same as that of this article on the African Review.
This is the first paragraph.
Javier Cavada, CEO and President of Highview Power spoke to African Review about the company’s cryogenic (air liquefaction) battery storage solutions and why they are a perfect fit for the continent
It appears to me, that the story, which started in a garage in Bishops Stortford, is going to have a happy ending for the world.
The article is a must read and I particularly liked this paragraph.
Cavada also noted how cryogenic technology complemented this transition. He added, “The main energy companies call our technology ‘pumped hydro in a box’ and that is how we have been making it. You can deploy over 1GWh without geographical constraints. There is no combustion, no emissions and no rare materials needed. All it comprises is some piping work, compressors and a generator, so it is pretty simple. Our mission is to enable a world that is grid powered by solar and wind, not fossil fuels, and this technology will help us achieve this.”
This is the brightest shade of green!
Malta Inc Energy Storage Explained
Malta Inc first came to my notice in 2018 and I wrote Gates Among Billionaires Backing Alphabet Energy Spinoff.
But I couldn’t find much information at the time, but they now have a web site that gives a good explanation.
This page on the web site is entitled Our Solution.
This infographic from the web page, lays out the key features.
This sentence outlines the method of operation.
The Malta energy storage system takes electricity, converts and stores that electricity as heat, and then converts it back to electricity to be redistributed on the electric grid. In charge mode, the system operates as a heat pump, storing electricity as heat in molten salt. In discharge mode, the system operates as a heat engine, using the stored heat to produce electricity.
The operation is explained in five stages.
- Collects – Energy is gathered from wind, solar, or fossil generators on the grid as electrical energy and sent to Malta’s energy storage system.
- Converts – The electricity drives a heat pump, which converts electrical energy into thermal energy by creating a temperature difference.
- Stores – The heat is then stored in molten salt, while the cold is stored in a chilled liquid.
- Reconverts – The temperature difference is converted back to electrical energy with a heat engine.
- Distributes – Electricity is sent back to the grid when it is needed.
Note.
- The operation of the system is based on well-understood thermodynamic principles.
- Entergy is stored as both heat and cold.
- It provides several hours of energy storage.
- Systems are built using standard components, that are readily available.
In some ways the Malta Inc PHES is based on similar principles to Highview Power’s CRYOBattery and Siemens Gamesa’s ETES.
Conclusion
This is a company to watch, as they seem to have got the technology right.
