Prowling for Solutions To Unleash Renewable Energy
The title of this post, is the same as this article on Toolbox.
It is a good summary of the best methods of storing renewable energy without using chemical batteries.
Gravitricity, Energy Vault and Highview Power are all mentioned.
This last paragraph, explains some of the philosophy behind Vermont looking seriously at Highview Power.
Vermont may well be tempted by liquid air energy storage because of its flexibility — simply requiring a two-acre site anywhere. One possible location could be near an abandoned power station. That’s a beautiful solution because the transmission lines that once transported the electricity from the plant are built and ready to use in the renewable era.
Note that a two-acre site is slightly smaller than a football pitch.
It is rather elegant to replace a coal- or gas-fired power-station with an environmentally-friendly energy storage system on the same site, which effectively does the same job of providing energy.
The article doesn’t mention employment, but surely many of the existing workforce can be easily retrained for the new technology.
Are The British Going To Rescue Vermont?
This article on the Scientific American is entitled To Store Renewable Energy, Try Freezing Air.
This is the sub-title of the article.
Such energy storage technology could help relieve congested transmission lines in places like Vermont.
It certainly is a must read, about the possibilities of energy storage and Highview Power in particular.
What Is A Pimby?
We all know that a Nimby (Not In My Back Yard!) doesn’t want fracking, a nuclear power station or a new railway to be built or something similar near to where they live.
But I believe, we could see the rise of a new type of protestor – the Pimby or a Please In My Back Yard!
I was reading this article on CleanTechnica, which is entitled Coal-Killing Long-Duration Energy Storage For Vermont (Vermont?!?).
The article is about Highview Power’s planned energy storage facility in Vermont, which I wrote about in Encore Joins Highview To Co-Develop Liquid Air Energy Storage System In Vermont.
This paragraph is from Highview.
“Unlike competing long-duration technologies, such as pumped hydro-power or compressed air, Highview Power’s CRYOBattery™ can be sited just about anywhere. The CRYOBattery has a small footprint, even at multiple gigawatt-levels, and does not use hazardous materials.”
You could imagine a community, , perhaps miles away from the nearest power station, where jobs and economic prospects are being held back by a dodgy power supply.
So the community might start to protest not about building perhaps a gas-fired station to satisfy their electricity needs, but in favour of a Highview Power system and some renewable wind or solar power.
Pimbys might also protest in favour of a new railway station or electrification of their branch line. Providing the power for the latter would be a good use for a Highview system.
Encore Joins Highview To Co-Develop Liquid Air Energy Storage System In Vermont
The title of this post is the same as that as this article on Vermont Biz.
This is the introductory paragraph.
Northern Vermont facility will help put more renewable energy on the region’s electric grid, establish first such facility in United States
According to the article, the planned system will be able to supply 50 MW for eight hours and store up to 400 MWH of electricity.
I do think that Highview Power could have a very viable solution to storing energy.
- The system is based on well-proven process technology, that Lord Kelvin would have understood.
- No exotic or difficult to obtain materials are needed.
- In the future, I believe systems of over a a GWh will be possible.
It is the best idea, I’ve seen, that could be the Holy Grail of energy storage.
Highview Power To Build Europe’s Largest Battery Storage System
The title of this post is the same as that as this article on The Chemical Engineer.
This is the first two paragraphs.
HighView Power, the designer and developer of the CRYOBattery, is to build what it claims will be Europe’s largest battery storage system, in the North of England. The project will also be the UK’s first commercial cryogenic energy storage facility at large scale.
The 50 MW/250 MWh clean energy storage facility could help the UK to achieve its goal of decarbonising industry, heat, power, and transport, as CRYOBattery emits zero emissions and could dramatically contribute to emissions savings compared to fossil fuel plants.
I spent long hours in my past modelling chemical plants and processes for ICI and my experience tells me, that this could be the Holy Grail of energy storage.
Consider.
- All of the technology needed is proven and much would have been understood, by Victorian collossi like Brunel, Kelvin and Reynolds.
- There are no expensive rare earths, chemicals or explosive gases.
- The system is scalable.
- There is no combustion and no emissions.
- The system can be built on any suitable site, thus opening up the possibility of distributed energy storage.
- Once the technology is working, this type of system, will be an ideal investment for a Pension Fund or Insurance Company, to get a good long-term return
I can see systems able to store a GWh of electricity being built, that can supply 200 MW of power for five hours.
I also feel non-battery storage like this and mechanical will make chemical batteries redundant for mass energy storage for grid applications.
After all, there’s only so much lithium and other important chemicals and that will be needed for energy storage in transport, like buses, trains and planes.
The Amount Of Energy Storage Needed In The UK
This is also a paragraph from the article.
According to early findings of the Storage and Flexibility Model (SFM) launched by the Energy Systems Catapult (ESC), to achieve an 80% reduction in CO2 emissions by 2050 compared to 1990 levels by 2050 the UK would need nearly 1,400 GWh of electric and thermal storage volume.
1,400 GWh of electricity storage is a very large amount. It would probably need a large proportion of all the lithium in the world, if conventional batteries were used. Highview will need none.
When you consider that the largest energy storage facility in the UK is Electric Mountain, which can only handle 9.1 GWh, building the 1,400 GWh of energy storage will be a massive undertaking.
But building perhaps a hundred or two of larger versions of this type of system and distributing them all over the UK might be a very practical way of providing the energy storage.
Provided the UK economy is good with a healthy City of London, these systems should be easy to fund, as they are the sort of investment, that provides an adequate long-term return, that is ideal to fund pensions and insurance.
The Power Of Battery Storage
This article on Fastmarkets is entitled Neoen To Expand Li-ion Battery Capacity at Hornsdale Plant.
This is the introductory paragraph.
Australia’s Hornsdale Power Reserve, the world’s biggest lithium-ion battery plant, is set to expand capacity by 50% to 150 megawatts, according to Neoen SA, the French power producer that owns and operates the site.
If you read the article and the Wikipedia entry for Hornsdale Power Reserve (HPR), you’ll see why it is being expanded.
This paragraph is from Wikipedia.
After six months of operation, the Hornsdale Power Reserve was responsible for 55% of frequency control and ancillary services in South Australia.[11] By the end of 2018, it was estimated that the Power Reserved had saved A$40 million in costs, most in eliminating the need for a 35 MW Frequency Control Ancillary Service.
Somewhat surprisingly, the power is mainly generated by the associated Hornsdale Wind Farm.
These are some statistics and facts of the installation at Hornsale.
- There are 99 wind turbines with a total generation capacity of 315 megawatts.
- HPR is promoted as the largest lithium-ion battery in the world.
- HPR can store 129 MWh of electricity.
- HPR can discharge 100 MW into the grid.
- The main use of HPR is to provide stability to the grid.
HPR also has a nice little earner, in storing energy, when the spot price is low and selling it when it is higher.
It certainly explains why investors are putting their money in energy storage.
Wikipedia lists four energy storage projects using batteries in the UK, mainly of an experimental nature in Lilroot, Kirkwall, Leighton Buzzard and six related sites in Northern |England. One site of the six has a capacity of 5 MWh, making it one of the largest in Europe.
But then we have the massive Dinorwig power station or Electric Mountain, which can supply ,1,728-MW and has a total storage capacity of 9.1 GWh
Consider.
- Electric Mountain has seventy times the capacity of Hornsdale Power Reserve.
- Electric Mountain cost £425 million in 1984, which would be a cost of £13.5 billion today.
- Another Electric Mountain would cost about £1.6 billion per GWh of energy storage.
- Hornsdale Power Reserve cost $ 50 million or about £26 million.
- Hornsdale Power Reserve would cost about £0.2 billion per GWh of energy storage.
So it would appear that large batteries are better value for money than large pumped storage systems like Electric Mountain.
But it’s not as simple as that!
- There aren’t many places, as suitable as North Wales for large pumped storage systems.
- Omce built, it appears pumped storage system can have a long life. Electric Mountain is thirty-five years old and with updating, I wouldsn’t be surprised to see Electric Mountain in operation at the end of this century.
- Battery sites can be relatively small, so can be placed perhaps in corners of industrial premises or housing developments.
- Battery sites can be built close to where power is needed, but pumped storage can only be built where geography allows.
- Pumped strage systems can need long and expensive connections to the grid.
- I think that the UK will not build another Electric Mountain, but will build several gigawatt-sized energy storage facilities.
- Is there enough lithium and other elements for all these batteries?
- Electric Mountain is well-placed in Snowdonia for some wind farms, but many are in the North Sea on the other side of the country.
In my view what is needed is a series of half-gigawatt storage facilities, spread all over the country.
Highview Power looks to be promising and I wrote about it in British Start-Up Beats World To Holy Grail Of Cheap Energy Storage For Wind And Solar.
But there will be lots of other good ideas!
British Start-Up Beats World To Holy Grail Of Cheap Energy Storage For Wind And Solar
The title of this post is the same as that of this article on the Daily Telegraph.
If you think it sounds too good to be true, then watch this video from the company behind the technology; Highview Power.
The basic principle is very simple.
- Electricity is used to turn air into liquefied air using refrigeration technology, that has been around for donkeys years.
- This is stored in tanks under pressure.
- To retrieve the energy, the liquid air is allowed to evaporate and creates electricity through a turbine and generator.
These engineers have taken several pieces of readily available industrial equipment, put it together in a novel way. to create an energy storage system.
I believe that this could be the Holy Grail of energy storage!
Why?
In World’s Largest Wind Farm Attracts Huge Backing From Insurance Giant, I discussed how Aviva have invested a billion pounds in wind farms, as it gives them the sort of long-term return they need to provide pensions and pay out insurance claims.
But if you own a Gigawatt-sized wind farm in the North Sea, one thing is missing; the ability to store that energy in an affordable way.
So by investing in this type of energy storage and coupling it with their own wind farms, Aviva can control the output of the wind farms to what the National Grid needs.
All it needs is some more money, that needs a home. And Aviva have lots of that!
It’s also an investment with an ethical and green profile.
- No polluting technology.
- Proven technology.
- Zero-carbon technology.
- Non-toxic technology.
- No use of exotic and scant resources.
- No expensive or dangerous fuel
- Affordable technology
Systems can also be distributed to where they are needed or where there is surplus electricity.
If you want to know more, watch the video and then look at other videos for Highview Power.
How Much Energy Can Highview Power’s Systems Store?
The biggest energy storage system in the UK is Electric Mountain, which has a power output of 1,728 MW and an energy storage capacity of 9.1 GWh.
That is some battery and it was built in the 1970s for a cost of £425 million, which would be £1.3billion today.
In a video it is claimed that Highview Power are designing a storage system, which has a power output of 200 MW and an energy storage capacity of 1.2 GWh.
You would only need to build nine and you’ve got another Electric Mountain!
Perhaps to maximise security of supply and obtain a fast response, the systems could be placed in Cumbria, Essex, Humberside, Kent, Merseyside, Norfolk, Suffolk, Thurso and Yorkshire.
Would We Need Nuclear Power?
Probably not!
For the same amount of money as a large nuclear power station, you’d get an awful lot of offshore wind farms and the storage thrown in.
Conclusion
This technology could solve the world’s energy problems.

SA Zinc Mine To Be Converted To Compressed Air Energy Storage Facility
The title of this post, is the same as that of this article on Energy News Biulletin.
This is the first paragraph.
The Australian Renewable Energy Agency has announced a $6 million spend for company Hydrostar Australia to progress the nation’s first energy storage project using compressed air, with another $3 million provided by the South Australian government’s renewable energy fund.
There are other articles about energy storage in Australia, but then I suppose the country, can create lots of solar energy during the day and storing some of it is important.Using compressed air to store energy underground, seems increasing to be mentioned in the media.
Seabed Rocks Could Act As Green Energy Stores
The title of this post is the same as that of this press release from the University of Strathclyde.
This is the first four paragraphs.
Rocks in the seabed off the UK coast could provide long-term storage locations for renewable energy production, new research suggests.
An advanced technique could be used to trap compressed air in porous rock formations found in the North Sea using electricity from renewable technologies.
The pressurised air could later be released to drive a turbine to generate large amounts of electricity.
Using the technique on a large scale could store enough compressed air to meet the UK’s electricity needs during winter, when demand is highest, the study found.
I read about this in today’s copy of The Times, which also says the following.
- There are suitable areas in the North and Irish Seas that can be used.
- The rocks could store fifty percent more energy than we used January and February.
As similar technology is being used in salt caverns in Germany and the United States, I feel that the idea has possibilities.
