Boralex Commissions BESS At Wind Farm In France In EU-Supported Demonstration Project
The title of this post, is the same as that of this article on Energy Storage News.
These two paragraphs outline the project.
Canada-based renewable energy firm Boralex has turned on a 3.3MWh battery storage unit attached to a wind farm in France.
The battery storage project has been installed at the site of the Plouguin wind farm, an 8MW generating facility in the Finistere department of Brittany, northwest France.
Note.
- The project was co-financed by the European Union through its European Regional Development Fund (ERDF).
- The project was launched to demonstrate the technical feasibility of a hybrid wind-plus-storage project.
- Boralex added in its announcement that the project will contribute to the stability of the French electricity grid.
There will be a lot of projects like this in the future.
This paragraph makes an interesting point about using batteries with solar and wind power.
Wind farms are less frequently hybridised with energy storage than solar PV because of the larger minimum project size and less predictable variability, with sharper peaks meaning heavier battery cycling and potentially faster degradation.
My control engineering knowledge and experience says that larger power sources and those that are highly variable will need batteries with more capacity for the same stability and quality of power output.
This sounds to me like a very good reason for developing larger and more affordable batteries, like those of Cheesecake Energy, Energy Dome, Gravitricity and Highview Power.
It also probably means that to stabilise several gigawatts of wind power, you need a very large amount of storage, that can only be provided by pumped storage hydroelectricity.
Conclusion
A very large amount energy storage is going to be needed.
Projects like these are essential to make sure we use them to their full possibilities.
Highview Power And Ørsted Collaborate To Unlock Greater Value From The Next Generation Of Wind Farms
The title of this post, is the same as that of this press release from Ørsted.
This is the sub-heading.
Highview Power and Ørsted have signed a Memorandum of Understanding aiming to prove the feasibility and economic value of co-locating long duration energy storage with offshore wind.
This first paragraph indicates how the two companies will work together.
The two companies will carry out detailed technical analysis and an economic assessment during 2023 that will investigate how combining Ørsted’s wind technology with Highview Power’s liquid air energy storage can deliver a stronger investment case for future offshore wind projects by reducing wind curtailment, increasing productivity, and helping the move to a more flexible, resilient zero carbon grid.
This all good stuff and as a Control Engineer, I know, there is a very good chance, it will bring forward worthwhile benefits.
Diversifying A US$200 billion Market: The Alternatives To Li-ion Batteries For Grid-Scale Energy Storage
The title of this post, is the same as that of this article on Energy Storage News.
This is the introductory paragraph.
The global need for grid-scale energy storage will rise rapidly in the coming years as the transition away from fossil fuels accelerates. Energy storage can help meet the need for reliability and resilience on the grid, but lithium-ion is not the only option, writes Oliver Warren of climate and ESG-focused investment bank and advisory group DAI Magister.
Oliver starts by saying we need to ramp up capacity.
According to the International Energy Agency (IEA), to decarbonise electricity globally the world’s energy storage capacity must increase by a factor of 40x+ by 2030, reaching a total of 700 GW, or around 25% of global electricity usage (23,000TWh per annum). For comparison, this would be like swelling the size of the UK’s land to that of the USA.
Similar to how “nobody ever gets fired for buying IBM”, lithium-ion holds a similar place in grid scale electrical storage today.
And just as IBM did in the last decades of the last century, the builders of lithium-ion will fight back.
He then lists the problems of grid-scale lithium-ion batteries.
- Shortage of cobalt.
- Toxic and polluting extraction of some much needed metals and rare earths from unstable countries.
- Lack of capacity to load follow.
- Limited lifespan.
He does suggest vehicle-to-grid can provide 7TWh of storage by 2030, but it has similar problems to lithium-ion grid scale batteries.
Finally, he covers these what he considers several viable methods of energy storage in detail.
He introduces them with this paragraph.
No single killer application or technology exists to get the job done. Diversification is key with success dependent on the wide-scale adoption of multiple grid-scale energy storage solutions.
- Energy Dome – Italy – Stylish Use of CO2
- Augwind Energy – Israel – Stores Energy As Compressed Air Underground
- Cheesecake Energy – UK – Stores Energy As Heat And Compressed Air
- Highview Power – UK – Stores Energy As Liquefied Air
- Ocean Grazer – Netherlands – Ocean Battery
- RheEnergise – UK – High Density Hydro
- Lumenion – Germany/Japan – Stores Energy As Heat
- Energy Vault – Switzerland – Raising And Lowering Of Weights
Note.
- All systems are environmentally-friendly and use readily-available materials like air, water, sea-water, steel and concrete for their systems.
- The most exotic materials used are probably in the control computers.
- Some systems use readily-available proven turbo-machinery.
- Most systems appear to be scalable.
- All systems would appear to have a working life measured in decades.
- I would expect that most well-educated teenagers could understand how these systems worked.
Only Augwind Energy and Lumenion are new to me.
He finally sums up the economics and the market potential.
Our ability to expand energy storage capacity is one of the most pressing issues that will determine whether this defining ‘transitional’ decade is a success. But we’ll need to invest wisely into the right technologies that get the greatest bang for the buck (in terms of GWh capacity and return on capital) given the limited lifespan of Li-Ion and the decarbonisation of the grid.
At a current capital cost of US$2,000 per kW quoted by the US National Renewable Energy Laboratory (NREL) for 6-hour Li-ion battery storage, the 700GW of capacity needed by 2030 equates to around a US$1.5 trillion market over the coming decade, making it worth nearly US$200 billion a year.
The Energy Storage News article is a comprehensive must read for anyone, who is considering purchasing or investing in energy storage.
I have some further thoughts.
From My Experience Would I Add Any Other Systems?
I would add the following.
- Form Energy, because its iron-air battery is well-backed financially.
- Gravitricity, because it can use disused mine shafts to store energy and the world has lots of those.
- STORE Consortium, because its 3D-printed concrete hemispheres, that store energy using pressurised sea-water can be placed within a wind farm.
I also suspect that someone will come up with an energy storage system based on tidal range.
Finance
When we started Metier Management Systems, finance to breakout from the first initial sales was a problem. We solved the problem with good financial planning and an innovative bank manager who believed us all the way.
David, was a rogue, but he was a rogue on the side of the angels. Long after Metier, he even came to my fiftieth birthday party.
David would have found a way to fund any of these systems, as they tick all the boxes of demonstrated, environmentally-friendly, safe and understandable. They are also likely to be bought by companies, governments and organisations with a high net value, a very respectable reputation and/or large amounts of money.
I also think, that just as we did with the original Artemis project management system, some of these systems can be leased to the operators.
Second-Use Of Systems
Several of these systems could be moved on to a new location, if say they were supporting an industry that failed.
That would surely help the financing of systems.
Wind Power For 1.2m Homes Is Wasted Because Of Lack Of Storage
The title of this post, is the same as that of this article on the Daily Telegraph.
These two paragraphs outline what happened.
Enough wind power to supply 1.2m homes a day was wasted over winter because there is no capacity to store extra energy generated on gusty days, according to new research.
National Grid’s electricity system operator asked wind turbines which were expected to generate about 1.35 terawatt-hours of electricity between October and January to switch off instead because they were not needed to meet demand at the time, according to the consultancy Stonehaven.
The problem has been flagged up by Rupert Pearce of Highview Power, who in my view could have a solution with their CRYOBatteries.
Pearce is quoted as saying this.
Renewable energy storage is essential to powering a cleaner, cheaper, always-on Britain.
By capturing and storing excess renewable energy, which is now the UK’s cheapest, most secure and most abundant form of energy, we can power Britain’s homes and businesses with renewable green energy, taking millions of tonnes of carbon out of the atmosphere and ending a culture of reliance on expensive foreign imports.
He’s too bloody right! And my experience of mathematical modelling large vessels at ICI in the 1970s, says that Highview Power have one of the sensible solutions to large scale energy storage.
First Offtake Deal Signed For 500MW/4,000MWh Advanced Compressed Air Energy Storage Project In California
The title of this post, is the same as that of this article on Energy Storage News.
These three paragraphs explain the deal.
Advanced compressed air energy storage (A-CAES) company Hydrostor has signed a power purchase agreement (PPA) for one of its flagship large-scale projects in California.
Central Coast Community Energy, one of California’s several dozen Community Choice Aggregator (CCA) non-profit energy suppliers, has signed a 200MW/1,600MWh energy storage PPA with a 25-year term with Toronto-headquartered Hydrostor for its Willow Rock Energy Storage Center.
That’s just under half of the output and capacity of the planned 8-hour, long-duration energy storage (LDES) facility, which is designed to be 500MW/4,000MWh. This is its first offtake deal, but the company is in discussion for others to take the rest of the plant’s available resource.
The article says that Hydrostor aim to have the plant online by 2028.
This segment describes their current projects.
It is currently working on large-scale projects with around 9GWh storage capacity in total across two sites in California as well as another in Australia.
Together with Willow Rock in Kern County, Hydrostor is developing the 400MW/3,200MWh Pechos Energy Storage Center in San Luis Obispo County, California, and the 200MW/1,500MWh Silver City Energy Storage Center in Broken Hill, New South Wales, Australia.
On its UK Projects page, Highview talks about a 200MW/2.5GWh facility in Yorkshire, which puts the two companies in similar markets, with Hydrostor appearing to have slightly larger systems under development.
Conclusion
It will be interesting to see how this technology progresses and which company does best in what is a very large energy storage market.
How Liquid Air Could Solve The UK’s Energy Conundrum
The title of this post, is the same as that of this article on The Telegraph.
The article is mainly an article that described the technology and it discloses a few facts.
- The Carrington plant should be delivered in 2024.
- Carrington will be a 30 MW/30 MWh system.
- Efficiency is around 50 %, but there are possibilities to raise it to 70 %.
- Australia is mentioned as a market.
- It is likely to be paired with supercapacitors or a flywheel to have a quick start.
- It seems to me, that turning an idea into a practical system is taking a lot of work and money, and a bit of a rethink.
But hopefully, the system will eventually be developed, as it does promise to be an energy storage system, that doesn’t make high demands on the environment in terms of expensive metals and rare earths.
Is Something Happening At Highview Power?
It seems to be impossible to connect to the Highview Power web site.
I get the message, that my security is not private.
There is also no news of the company in the last month.
Highview Power In The Daily Express
This article in the Daily Express is entitled The Storage Sites Around The UK That Could Provide Cheap Power To Millions Of Homes.
Highview Power gets a large mention for its plan for twenty storage sites around the UK.
This is said about their planned sites at Carrington and on Humberside.
It is hoped that the first plant, a £250million Manchester station, will come online as early as 2024. It will have a 30megawatts capacity, able to store 300megawatt hours of electricity, enough to supply 600,000 homes with clean power for an hour.
The next plants will be even larger in scale, with four a five planned for Humberside with a 200megawatt/2.5gigwatt hour capacity. The CRYOBattery site would be able to store excess energy generated by the Dogger Bank, Hornsea and Sofia wind farms.
There is also a comprehensive map, with sites indicated at places like Aberdeen, Anglesey, Inverness, Liverpool, Montrose, Norfolk and Sizewell.
The sites seem to be following the wind, which is where excess power needs to be stored and released, when the wind is on strike.
Cryogenic Energy Plan Could Bring Jobs Boost To Largs
The title of this post, is the same as that of this article on the Largs and Millport Weekly News.
These paragraphs outline the project.
Proposals for a ground-breaking cryogenic energy storage system at Hunterston Marine Construction Yard have been unveiled..
The proposed development will generate 49.9MW of electricity – and is expected to create around ten jobs.
The cryogenic energy storage system comprises three main processes: a charging system, an energy store, and power recovery.
It turns ambient air into liquid, stores the liquid air in tanks and, when needed, expands the liquid air into a gas which generates electricity.
Highview Power are mentioned as behind the project.
As the report is dated the 21st if August 2021, is this another of Highview Power’s might-have-been projects?
UK Group Plans First Large-Scale Liquid Air Energy Storage Plant
The title of this post, is the same as that of this article on the FT.
This is the first paragraph.
Highview Power is attempting to raise £400mn to fund project with capacity to supply 600,000 homes.
Note.
- This battery will have an output of 30 MW and a storage capacity of 300 MWh.
- The battery will be built at Carrington, near Manchester.
- Highview Power hope it will be opened by the end of 2024.
- It appears that the £400 million will also be used to start the engineering for another four batteries.
The article gives a detailed history of the company.
