New-Age Battery Pioneer Zinc8 Ties Up With Indian Transformer-Maker For Global Push
The title of this post, is the same as that of this article on Recharge.
I think, it shows the way the energy storage market is going, where alliances are being formed to exploit the new technologies.
A transformer maker and a battery storage company must be a good match.
Conclusion
I still very much feel that Zinc8, will be a success.
Preliminary Sampling Indicate Significant Lithium Grades In Geothermal Waters At United Downs Project, Cornwall
The title of this post, is the same as that of this article on Think Geoenergy.
This is the introductory paragraph.
Cornish Lithium releases announcement on finding “globally significant” lithium grades in geothermal waters at the United Downs Deep Geothermal Power Project in Cornwall, UK and is now preparing for work on a pilot plant.
The article gives a full explanation.
There is more on this press release on the Cornish Lithium web site.
Siemens To Build One Of Europe’s Largest Energy Storage Systems
The title of this post, is the same as that of this article on Smart Energy International.
This is the introductory paragraph.
Siemens Smart Infrastructure and Fluence have been awarded a contract by the Portuguese energy provider EDA – Electricidade dos Açores to build a battery-based energy storage system on Terceira.
Read the article, as it shows how battery storage and advanced methods of generation, can transform the electricity systems of islands and other remote places.
We will be seeing many systems like this, all over the world.
Lightweight Green Supercapacitors Could Quickly Charge Devices
The title of this post is the same as that of this article on Texas A & M Today.
This is the sub-title.
Texas A&M researchers have designed a new energy storage device that can store a charge up to 900 times greater than state-of-the-art supercapacitors.
It appears what they have developed is plant-based.
They appear to use lignin and potassium permanganate to create the electrodes for a supercapacitor.
It looks to be interesting research.
Energy Storage Takes On Weird New Forms As Sparkling Green Future Takes Shape
The title of this post, is the same as that of this article on CleanTechnica.
The first section is entitled Gravity-Enabled Energy Storage Tested By Scotland’s Gravitricity and explains it well.
It then writes an interesting aside about pairing a Gravitricity system, with an idea from GE, in a section, which is entitled A Wind Power & Energy Storage Twofer, Maybe.
GE were proposing a lattice-style wind-turbine tower, so why not put a Gravitricity system inside?
Hence the maybe in the section title!
I can imagine an office or residential tower with a Gravitricity system built into the lift core in the centre of the building. Top the building with solar panels or wind turbines and you’re going some way towards a building that could be self-sufficient in energy.
Putting two and two together, so they add up to five, is the best way to improve efficiency.
The last section is entitled How To Do Energy Storage Without Any Energy Storage.
As I have never played a computer game, I don’t understand it, but it is based on research at two reputable universities; Delft University of Technology (TU Delft) in the Netherlands and Northwestern University in the US.
Conclusion
We will be seeing weirder and weirder ideas for energy generation and storage in the future.
Generating Clean Energy From The Coal Mines
The title of this post, is the same as that of this article on The Engineer.
This is the introductory paragraph.
With a number of the UK’s abandoned coal mines being repurposed for green energy projects, Jon Excell asks whether the legacy of Britain’s polluting industrial past could hold the key to its low carbon future?
A few points from this must-read article.
- We spend £2.4 billion every year dealing with the water in abandoned mines.
- The huge volumes of mine water – heated by geological processes to temperatures as high as 40˚C – could actually help power the UK’s shift to a zero-carbon economy.
- The Coal Authority now has around thirty different projects.
- there is an estimated 2.2 million GWh of annually renewing zero carbon geothermal energy held within the mines.
- Heat can be extracted using boreholes, heat pumps and heat exchangers.
- The mines can be used to store energy as waste heat.
- I particularly liked the use of a mine shaft as a thermal flask, which is being developed at Shawfair in Scotland.
The article then talks about Gravitricity.
This is an extract.
According to Gravitricity project development manager Chris Yendell, the potential for the technology is huge.
Research carried out for the company by KPMG identified 60,000 vertical shafts of 200m or greater in Germany alone. Indeed, many of these shafts as deep as 1000m. Meanwhile, following discussions with the Coal Authority, the team believes that in the UK there are at least 100 potentially viable deep vertical mineshafts. “Based on that you could look at a future portfolio in the UK of 2.4GWh of capacity, based on a 10MW peak system with a capacity of 24MWh” said Yendell.
The article finishes on an optimistic note, by outlining how in the former mining areas, there is lots of expertise to maintain and run these new green energy systems, that will replace coal’s black hole.
Conclusion
Coal could be the future! But not as we know it!
Rolls-Royce To Expand Battery Production Capacity To Meet Demand For Microgrids
The title of this post, is the same as that of this article on Mucrogrid Knowledge.
It does appear, that they are taking the fight to their problems.
Vivarail Targets Overseas Markets
The title of this post, is the same as that of this article on Rail Magazine.
This is an extract from the article.
Shooter told RAIL: “We are at the moment putting together a bid for an operator – not in this country – where the routes would be up to 500 miles long, to be provided totally with battery trains using this device.
“This bid we are putting together contemplates trains that are running for several hours – 60 to 70 miles between charging stations, but possibly going twice that far in emergency if the charging station should go down.”
By this device I suspect they mean their Fast Charge device, which is described in this press release from Vivarail.
This extract describes how it works.
The concept is simple – at the terminus 4 short sections of 3rd and 4th rail are installed and connected to the electronic control unit and the battery bank. Whilst the train is in service the battery bank trickle charges itself from the national grid – the benefit of this is that there is a continuous low-level draw such as an EMU would use rather than a one-off huge demand for power.
The train pulls into the station as normal and the shoegear connects with the sections of charging rail. The driver need do nothing other than stop in the correct place as per normal and the rail is not live until the train is in place.
That’s it!
That sounds simple to me.
Where Would This Possible Order Be From?
I have ridden in a Vivarail battery train, as I wrote in Battery Class 230 Train Demonstration At Bo’ness And Kinneil Railway.
I have also ridden the diesel variant, as I wrote in A First Ride In A Revenue-Earning Class 230 Train.
I very much feel, I can list a few of the good qualities of the trains.
Big Windows
The big windows give a good view, so I wonder if the trains would work well on a railway noted for its scenery.
Quietness
I have ridden in two battery trains.
The other was Bombardier’s Class 379 BEMU, that I wrote about in Is The Battery Electric Multiple Unit (BEMU) A Big Innovation In Train Design?.
Both were extremely quiet.
No Infrastructure Required
Except for the charging stations, no infrastructure is required.
Sturdy Engineering
Although the trains were only originally built for the London Underground, they are sturdily-built trains, as they used to share tracks with full-size trains.
I suspect, they are certified to share tracks with freight trains, as they do on the Marston Vale Line.
A Range Of Interiors And Customer Facilities
Although the trains tend to use the old London Underground seat frames, they have a range of interiors, which seem to be well-designed and comfortable.
I have been on Class 230 trains, with tables, a single toilet, onboard Wi-Fi, and electrical charging points.
Zero-Carbon
The trains are probably as near to zero-carbon, as any! Especially, if all the Fast Charge stations are powered by renewable electricity.
Remote Servicing
The trains have been designed for remote servicing.
Conclusion
All of these qualities lead me to think, that an ideal line in the UK could be the Far North Line, between Inverness and Wick and Thurso.
Although the train ticks a lot of boxes, it could well be too slow, It is also only a 160 mile route and not five-hundred
But there must be quite a few long, scenic lines in countries, where a passenger service needs to be added to a freight line, that perhaps serves a remote mining town.
Sweden and Norway are surely possibilities, but Finland is ruled out because it is Russian gauge.
Could the trains end up in parts of Africa, Canada and the United States?
Who knows?
Flywheel-Lithium Battery Hybrid Energy Storage System Joining Dutch Grid Services Markets
The title of this post, is the same as that of this article on Energy Storage News.
This is the introductory paragraph.
A hybrid energy storage system combining lithium-ion batteries with mechanical energy storage in the form of flywheels has gone into operation in the Netherlands, from technology providers Leclanché and S4 Energy.
These are some points from the article.
- The system contains 8.8MW / 7.12MWh of lithium-ion batteries.
- Six flywheels add up to 3MW of power.
- The 5,000kg KINEXT flywheel operates at 92% efficiency.
- The flywheels do not suffer from long-term degradation.
The article finishes with a discussion about the pros and cons of flywheel storage.
In the 1960s, when I worked at Enfield Rolling Mills, I heard stories of their 97-tonne flywheel on their main rolling mill for reducing copper wirebars to coils of wire for drawing into electrical wire for use in its myriad applications.
- Copper wirebars, were bars of refined copper about a metre long and perhaps ten centimetres square, which arrived at Enfield by barge from the London docks up the River Lea.
- The main rolling mill had arrived in Enfield, as reparations after the First World War. It had the Krupp trademark of three interlocked railway tyres all over it. It was probably built just after the start of the Twentieth Century.
- The flywheel was spun by an electric motor and the rolling mill itself, where wirebars snaked through a series of rollers of diminishing size, was driven from the flywheel.
- The arrangement meant that continuous power was supplied by the motor rather than intermittent power.
It was a fascinating process to watch, as the wire snaked through and was turned at each mill by an operator called a catcher, with a large pair of tongs. That was not a job for weaklings. The section I worked for, were always dreaming of automating the catching process. But I don’t think they ever did!
The flywheel was the source of legendary stories, many of which which have probably been exaggerated over the years.
One concerned its installation, where it was realised that there was no crane big enough to lift it from where it was delivered to the mill.
So the chief engineer, an Austrian Jew called Schimmatovich, devised a plan where men were used to roll it in to place. Like with the pyramids or in a concentration camp, where Shimmy had been incarcerated, as he said at the time.
It was successfully done on a Sunday morning, and after it was successfully secured, the Managing Director, who was called something like Freddy Pluety, suggested everybody join him in the Sports and Social Club for a drink.
So Freddy led a crocodile of perhaps a hundred across the road and walked into the Club, where the steward was just shutting up. Freddy ordered the drinks, but was told No! So Freddy picked him up and sat him on the bar. Freddy then noticed there were two very large and thirsty men on either side, so he said to them, “Are you going to hit him first or am I?”
They all got their drinks.
There must be many legendary industrial stories like this, that have been forgotten.
Gresham House Energy Storage Fund Has Staying Power
The title of this post, is the same as that of this article in the Tempus column of The Times.
It is a good explanation of how energy storage funds like Gresham House work.
I believe they are very much the future.
Some of the new forms of energy storage, that I talk about on this blog tick all of the boxes and may even satisfy an extreme supporter of Extinction Rebellion.
- Extremely environmentally friendly.
- Higher energy-density than lithium-ion
- Lower cost per GWh, than lithium-ion
- Much longer life than lithium-ion.
- Safe to install in built up areas.
- GWh-scale storage in a football pitch space or smaller.
The UK’s largest battery is the 9.1 GWh Electric Mountain pumped storage system in Snowdonia and there is talk about over 100 GW of offshore wind turbines in UK waters. There will be masses of energy storage built in the UK in the next forty years to support these wind turbines.
Conclusion
Companies like Gresham House Energy Fund seem to have developed a model, that could provide the necessary energy storage and a safe reliable home for the billions of pounds in the UK, that is invested in pension funds.
Lithium-ion batteries will be reserved for mobile applications.
