Gravitricity Explores Czech Coal Mine For MW-Scale Storage
The title of this post, is the same as that as this article on renews.biz.
This is the first paragraph.
Scottish energy storage outfit Gravitricity is exploring the potential to transform a former Czech coal mine into an energy storage plant with a capacity of up to 8MW.
It all sounds like a good use for a disused coal mine.
According to the article, future systems with multiple weights could store up to 25 MWh.
Fortescue Unveils Green Investment Framework
The title of this post, is the same as that of this article on Mining Weekly.
This is the first paragraph.
Iron-ore major Fortescue Metals this week launched its Sustainability Financing Framework, enabling the future issuance of green and social debt instruments that will support investments in eligible green and social projects.
I have to admit, that I thought something like this might happen, after seeing all the Fortescue Future Industries publicity on a bus, which I wrote about in Green Hydrogen Can Save Us. But Waiting For It Won’t.
I did say this in that post.
Andrew Forrest is intending to get his message across to the City.
But I didn’t take any action.
I can see other companies and investment trusts following Andrew Forrest’s lead.
Harmony Energy Income Trust Eyes IPO To Develop 213.5MW Of Tesla Battery Storage
The title of this post, is the same as that of this article on Solar Power Portal.
The article is a very detailed look at Harmony and their development of energy storage, using Tesla hardware and software.
It also has things to say about the energy storage market in general.
This is a paragraph.
Paul Mason, managing director of the Investment Adviser, said battery energy storage offers exciting growth potential, with an expected requirement of up to 43GW by 2050 from just 1.2GW now.
It is certainly looking that companies like Harmony Energy Income Trust will be important in funding this extreme growth of energy storage.
‘Unique’ Solar-Storage Solution Providers Plot 300MW / 3.6GWh Australia Project
The title of this post, is the same as that of this article on Energy Storage News.
The first two paragraphs outline the system.
A 1,200 hectare site in South Australia has been secured by a developer hoping to use it to build a 300MW solar power site with 3.6GWh of energy storage, based on a novel technology solution.
Europe-headquartered renewables company Photon Energy is working to roll out the technology created by Australian company RayGen. It combines a kind of concentrating solar power (CSP) + solar photovoltaics (PV) hybrid that RayGen calls ‘PV Ultra’, paired to a long-duration energy storage tech dubbed ‘thermal hydro’.
Thermal hydro appears to be an interesting concept, which uses hot and cold water reservoirs to store energy. Electricity is retrieved using a Rankin cycle engine and the claimed roundtrip efficiency is seventy percent.
This power plant might seem to be very futuristic, but a 4MW solar with 3MW / 50MWh of energy storage project is already under construction and should go on-line in the middle of next year.
The developer; Photon Energy hopes to get the giga-plant ready-to-build by the end of 2023.
This concept could be a very useful one, where there is enough sun for concentrating solar power.
Hydrophilic Polymers: The Key To A Green Future
The title of this post, is the same as that of this article on Tech Xplore.
This is the first paragraph.
Researchers from the University of Surrey and the University of Bristol are working on innovative devices to tame and store carbon-free renewable energy from unpredictable sources such as wind and solar.
That got me interested and I read the whole article.
This abstract on SpringerLink gives a definition of hydrophilic polymers.
Hydrophilic polymers are those polymers which dissolve in, or are swollen by, water. Many compounds of major technical and economic importance fall within this definition, including many polymers of natural origin. Many foodstuffs—containing substantial amounts of carbohydrate and protein— can be classified as hydrophilic polymers, and some have important technical and industrial uses, apart from their nutritional value. For example, although over 95% of the starches produced from corn (maize), wheat, potato, tapioca, and other vegetable sources are used as foods (human or animal), the remaining quantity represents an important part of the technical polymer market. In fact, more than two-thirds of hydrophilic or water-soluble polymers used in industry are derived from polymers of natural origin, so coming from renewable resources (harvested crops, trees, waste animal products and so on), rather than petrochemical sources of finite availability.
This paragraph from the Tech Xplore article describes the research.
The Chemistry Department at Surrey is working with collaborators at Bristol, Professors Ian Hamerton and David Fermin, and Superdielectrics Ltd., an innovative British Research Company located at the Surrey Research Park to transform simple hydrophilic polymers which were originally developed for use as contact lenses, to realize a second critical energy storage process.
This could lead to the next generation of supercapacitors.
Conclusion
This is fascinating technology and it could save the world.
Long Duration Energy Storage Council — A New Global Industry Body — Launched At COP26
The title of this post, is the same as that of this article on Recharge News.
This is the first paragraph.
The CEO-led organisation aims to ensure that fossil-fuel back-up is replaced with long-lasting zero-carbon alternatives by 2040.
The membership includes major players in energy and energy storage.
Hopefully, they’ll ensure the world has enough energy storage.

Financial Incentive Needed To Drive UK Energy Storage
The title of this post, is the same as that of this article on pv Magazine.
This is the first paragraph.
The lack of an incentive regime for battery projects and the like – whether a fixed feed-in tariff or market-driven contracts-for-difference program – is likely to see the COP26 host miss its 100%-clean-power-by-2035 commitment, according to K2 Management.
As a Control Engineer, I would go for a market-driven contracts-for-difference program, which if properly setup should give feedback, so that eventually, storage and renewable energy production are in equilibrium with the power needed.
It’s not as if, we’re short of ideas for energy storage in the UK.
I think the breakthrough will come, when one of the big energy storage funds like Gresham House or Gore Street decides to back one of the viable environmentally-friendly energy storage concepts, that are currently under development.
I am watching energy storage, as I suspect there could be a big announcement at COP26.
Gore Street Energy Storage Fund Revenues Boosted Amid Market Volatility
Over the last few years, I have blogged about energy storage and two energy storage funds; Gore Street and Gresham House.
According to an article on Proactive Investors, with the same title as this post, Gore Street hasn’t been doing badly lately and says this about their recent performance.
Gore Street Energy Storage Fund PLC said its assets in Great Britain generated revenues two times above forecast in September and added that industry is only at the start of its growth curve.
When I saw the concept of an energy storage fund, as a Control Engineer, I liked it.
The wind doesn’t always blow and the sun doesn’t always shine, so something is needed to cover the gaps in the supply.
The obvious way to cover the gaps is to put a battery in the circuit.
- When the electricity supply is higher than the demand, the surplus electricity can be stored in a convenient battery connected to the grid.
- When the reverse is true and there is a deficit of electricity, the energy in the battery can be used to make up the difference.
The battery works with electricity, just like a bank works with money, except that batteries don’t pay interest.
- The battery owners do make money by buying electricity, when it’s cheap and selling it back at a higher price.
- Tesla and others will sell you both batteries and the controlling software.
- Some areas with perhaps high levels of wind and solar or unreliable power supplies could use batteries improve the robustness of the electricity supply.
- More wind and solar power will inevitably lead to a need for more energy storage.
- Battery technology will get cheaper in terms of the cost per MWh of storage.
- Battery-grid interface hardware will get more capable.
- Management software will get better at balancing the grid.
This all adds up to increasing opportunities at possibly lower costs for energy storage funds like Gore Street and Gresham House.
So we will inevitably see a growth of energy storage funds.
But they will change.
New Battery Technology
There are several new battery technologies, that I believe could prove to be competitive in terms of capacity, cost, efficiency and reliability when compared to lithium-ion batteries.
Some of them will also have the advantage of only using easy-to-source, environmentally-friendly materials in their manufacture.
Some battery technologies are also easier to scale up, in that your have a central unit, which is connected to several stores. So to scale up, you add another store to the central unit. Highview Power’s CRYOBattery works on this principle.
I can see energy storage funds taking off faster, when someone designs the ideal battery for their purposes.
More Energy Storage Funds
We will see more players enter the energy storage fund market, just as we saw more players enter the peer-to-peer lending market. But just as that market attracted men with silly hats, boots and horses, not all will be reputable. But there are signs that banks I might trust are entering the market.
I also think there could be a hybrid model, which is almost a cross between an energy storage fund and peer-to-peer technology.
But be prepared for financial innovation.
And always do due diligence before investing.
Local Energy Storage Funds
I can envisage sensible established players offering investment on a local basis.
So perhaps the residents of a town with a need for a battery, might like to help fund it.
Or just as Aviva with their strong connections to East Anglia helped to fund Greater Anglia’s new trains, they might fund a battery in perhaps Cromer.
Conclusion
I feel the future is very rosy for energy storage funds.
Railfreight Goes Back To Diesel As Electricity Costs Soar
The title of this post, is the same as that of this article on Railnews.
This is the first paragraph.
Some rail freight operators have abandoned electric traction, at least for now, because the price of electricity has been rising sharply. The electricity tariffs include a 40 per cent renewable energy tax, and following the latest rises diesel traction is now cheaper. The drivers’ union ASLEF is calling for the government to intervene, but Freightliner has already taken action.
This quote from the article is from ASLEF General Secretary; Mick Whelan.
Moving freight by rail rather than road is, inherently, a carbon-efficient mode of transport and an environmentally-friendly way of doing business. Electric-hauled freight services reduce emissions by 99 per cent; even moving goods by diesel traction reduces emissions by 76 per cent.
It looks to me, that a reputable and trusted environmental economist could come up with a compromise price and possibly a solution to improve the situation.
Possible solutions could include.
- Use of Biodiesel or Hydrotreated Vegetable Oil
- More energy storage.
Surely, though, the long term solution is hydrogen-powered locomotives. or dual-fuel locomotives, as I wrote about in Freightliner Secures Government Funding For Dual-Fuel Project.
ITM Power Raises £250 million
The title of this post, is the same as that of this media release from ITM Power.
There is a also a sub-title.
Manufacturing Expanded To 5GW Per Annum By 2024
ITM Power are certainly going large.
Given the number of plans for electrolysers published around the world, a 5GW annual production is by no means over ambitious.
