European Company To Make All Wind Turbine Blades 100 % Recyclable, Plans To Build Six Recycling Factories
The title of this post, is the same as that, of this article on offshoreWIND.biz.
This sub-heading outlines what the company plans to do.
A Denmark-based company Continuum plans to make all wind turbine blades fully recyclable and stop landfilling and their emissions-intensive processing into cement with six industrial-scale recycling factories across Europe, backed by investment from the Danish venture capital firm Climentum Capital and a grant from the UK’s Offshore Wind Growth Partnership (OWGP).
Other points in the article include.
- Continuum plan six factories.
- The first factory will open at Esbjerg in Denmark in 2024 and will be able to accept end-of-life blades this year.
- The second factory will be in the UK and it will be followed by others in France, Germany, Spain, and Turkey.
- Each factory will have the capacity to recycle a minimum of 36,000 tonnes of end-of-life turbine blades per year.
This paragraph describes, what will happen to the recycled turbine blades.
The company will recycle wind turbine blades into composite panels for the construction industry and the manufacture of day-to-day products such as facades, industrial doors, and kitchen countertops.
Looking at their description of their mechanical separation process, I suspect that they could recycle other products and manufacture lots of others.
GeoPura’s Construction World First
On the GeoPura web site there is a case study, which is entitled Construction World First.
These two paragraphs outline what was done.
Working in partnership with Siemens Energy our hydrogen fuel cell system, has provided off grid power and heat to National Grid’s UK Viking Link construction site.
The fuel cell system removes the need for diesel generators and provides innovative, sustainable, low carbon energy to the Viking Link interconnector project site.
The interesting thing, is that the heat that the hydrogen fuel cell gives out is collected and used to heat the remote site.
This last paragraph, explains the need for off grid power.
Off grid power is needed as this site didn’t have a grid connection for at least six to eight months, and the fuel cell system provided enough heat and power for the construction village during that time, removing the need for diesel generators.
There’s more in this Siemens Energy report.
Lithuanian Gas Pipeline Hit By Large Explosion
The title of this post, is the same as that of this article on the BBC.
This is the sub heading.
A large blast has hit a gas pipeline in the Pasvalys region of northern Lithuania, near the Latvian border.
This Google Map shows the location of the explosion.
Note.
- Country borders are marked as white lines.
- The site of the explosion at Pasvalis Vienkiemii, is marked with a red arrow.
- Pasvalis Vienkiemii is about a hundred miles from Vilnius.
- About a hundred miles to the East of Pasvalis Vienkiemii, is the point, where Belarus, Latvia and Lithuania meet.
- Russian territory is about a hundred miles further to the East.
I have experience of the quality of borders in that area.
South-West of Lithuania and lying between that country and Poland, there is the small Russian enclave of Kaliningrad.
These pictures show the border between Poland and the Kaliningrad enclave of Russia.
If the borders between Belarus, Latvia and Lithuania are as secure as this, they are almost an open invitation to saboteurs to enter and do damage.
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.
Zero-Carbon Lighting Of Large Spaces
In Cockfosters Train Depot – 12th January 2023, I took a series of pictures of Cockfosters Train Depot, of which these are a selection.
Note, the lamp clusters on top of tall poles to light the area.
You see lots of these lights to illuminate play areas, car parks, rail sidings and truck depots.
Could a SeaTwirl or another vertical wind turbine be placed as high as possible up the pole, that supports the lights?
- A battery would be needed for when the wind doesn’t blow.
- A control system would be used to use the lights, when they are needed.
- The poles would be able to be laid down, like many lights can be, for servicing from the ground.
Cockfosters would be an excellent location for a test, as the wind is always blowing and the site has an altitude of nearly a hundred metres.
National Grid Goes Carbon-Free With Hydrogen-Powered Substation Trial
The title of this post, is the same as that of this press release from National Grid.
These are the main bullet points.
- Hydrogen powered unit (HPU) quietly provided carbon-free electricity to National Grid’s Deeside Centre for Innovation
- Only emission is water
- HPUs could save an estimated 500,000 kg of carbon across all National Grid substation sites
I am an Electrical Engineer and I had never realised that all those electricity substations around the country need a backup electricity generator.
These four paragraphs describe the trial and the generator used.
A GeoPura 250kW hydrogen power unit (HPU) contained within a transportable shipping container measuring 7.2 m by 2.5 m was installed at DCI and produced the energy to power low-voltage equipment needed for National Grid’s innovation testing projects and site operations. The trial tested the capabilities and feasibility of HPUs as direct replacements for backup diesel generators across more than 250 National Grid substation sites, the data will now be analysed and shared later this year.
National Grid currently use diesel generators alongside batteries to provide backup power to a substation for key activities such as cooling fans, pumps, and lighting, enabling it to continue to perform its crucial role in the electricity transmission system.
These backup generators are rarely used and have less than a 1% chance of operating per year, however, on the rare occasion that backup power is required, changing from diesel to low-carbon emission alternatives have the potential to reduce carbon intensity by 90%* and save over 500,000 kg of carbon emissions.
The HPU at Deeside has power capabilities of up to 100 kW in continuous operation mode and up to 250 kW for 45 minutes and uses 100% green hydrogen. The unit is quieter and the hydrogen cannisters used to fuel the generators can be safely stored on site.
I have some thoughts.
Deeside Centre For Innovation
The Deeside Centre for Innovation (DCI), a state-of-the-art testing facility hosting a 400 kV modified substation, designed as a unique environment for development and trial of innovative technologies and practices.
I think there’s something rather cunning about the DCI, as it means that anybody with a good idea will probably approach National Grid for help with the testing.
Visit Deeside Centre for Innovation for more information.
GeoPura
GeoPura has a totally zero-emissions answer to how we’re going to generate, store and distribute the vast amount of energy required to decarbonise our global economies. Or so their web site says!
This page on GeoPura’s web site, gives several case studies of how they work.
They would appear to provide zero-carbon power in widespread locations for Winterwatch, Springwatch etc. for the BBC.
Wind Generation Sets New Record In UK Surpassing 21 GW
The eye-catching title of this post, is the same as that of this article on Renewables Now.
I regard anything over 20 GW as very good, as the UK’s average daily consumption is typically around 23 GW, so surely we can find a couple of gigawatts of biomass, gas, hydro or nuclear.
The Renewables Now article says this about UK electricity generation.
According to National Grid ESO, on Monday, January 9, wind accounted for 50.2% of British electricity, nuclear for 15.9%, gas for 13.1%, imports for 10%, biomass for 4.8%, hydro for 3.8%, solar for 1.3% and coal for 1.1%. Tuesday’s wind record may undergo slight adjustments in expectation of all data for yesterday.
I shall be following these figures.
- Especially, as Wikipedia says another 3 GW will be installed this year.
But it does seem that we’re getting there with renewable electricity.
A Thought On Energy Storage
I also think that if we are generating large amounts of electricity at times, which are more than we need, then we had better crack on and build lots of energy storage.
If we don’t need the energy and Europe or Ireland doesn’t want it, then we must store it, so that if the wind isn’t blowing we can recover it for a useful purpose, even if it is only selling it to the Germans to make hydrogen, which is used to replenish their stores.
Giant Solar Farm Project In Doubt After Disagreement Between Mike Cannon-Brookes And Andrew Forrest
The title of this post, is the same as that of this article on the Guardian.
This is the sub-heading.
Australian billionaires had backed $30bn Sun Cable venture designed to help power Darwin, Indonesia and Singapore but the company has gone into voluntary administration.
It does look like the administrators will be able to continue the project and look for more funding.
Qatar must be in the frame, as this link will probably cut some of their gas sales.
I wrote about this monster project in Sun Cable’s Australia-Asia PowerLink.
I wonder if this administration will have any effects on the prospects of the other giant intercontinental interconnectors?
- EuroAfrica Interconnector – See The EuroAfrica Interconnector
- EuroAsia Interconnector – See The EuroAsia Interconnector
- Morroco-UK Power Project – See Moroccan Solar-Plus-Wind To Be Linked To GB In ‘Ground-Breaking’ Xlinks Project
- TransPacific Interconnector – See Chile Wants To Export Solar Energy To Asia Via 15,000km Submarine Cable
The economics will decide. But I do think, the last one could be a bit ambitious.
Would A Solar Roof With Added Vertical Turbines Work?
This picture shows Oakwood station on the Piccadilly Line.
Note.
- The station is the second most Northerly on the line.
- It opened in 1933.
- It is a classic Charles Holden design.
- It is a Grade II* Listed building.
- The station is on top of a hill and has an elevation of 71 metres above sea level.
This Google Map shows a close-up of the roof.
There might be a few aerials on the roof, but no solar panels.
Oakwood’s Location And Weather
I used to live near Oakwood station and it had its disadvantages.
- Cycling home was always up a steep hill.
- It could get very cold at times.
There even used to be a plaque at the station, which said that if you flew East, the first land you would hit would be the Urals.
Oakwood station could be an ideal renewable power station.
- The concrete and brick box of the station is probably exceedingly strong.
- Solar panels could cover the flat roof.
- SeaTwirls or other vertical turbines could be mounted around the solar panels.
- There could still be spaces for the aerials.
- I wonder what the reaction of English Heritage would be.
Should we call this mixed solar and wind power generation, hybrid renewable energy? Or do we overdo, the use of hybrid?
London Underground have other stations of a similar design including Sudbury Town and Acton Town.
The Wider Area To The West Of Oakwood Station
This Google Map shows the area to the West of Oakwood station.
Note.
- The striped roofs at the top of the map, with sidings for trains to the North, is Cockfosters Train Depot for the Piccadilly Line..
- The large building in the South-West corner is Southgate School, which I watched being built in the early 1960s, from my bedroom window in our house opposite. It is a concrete frame building typical of the period.
- Oakwood station is at the East side of the map and indicated by a London Underground roundel.
I think the possibilities for hybrid power generation in this area are good.
Cockfosters Depot
Cockfosters Depot could be an interesting site to develop as a renewable power station.
- There’s no way the site could be developed for housing, as it’s in the Green Belt.
- Road access is bad, but access for trains is good.
- I estimate that the depot is an area of at least five square kilometres.
- It’s still windy in the depot.
But it could have a solar roof and a few vertical wind turbines over the whole depot as designs and panels improve.
Southgate School
Southgate School could have a similar setup to Oakwood station.
Opportunities At Cockfosters Station
This Google Map shows a 3D image of Cockfosters station and the buildings around it.
Note.
- Cockfosters station is indicated by the roundel.
- The station is a Grade II Listed building.
- The station has an elevation of 97 metres.
- Half of the station car park is going to be turned into housing.
- Trent Park lies to the North of the station.
- The road in front of the station is Cockfosters Road, which to the North joins the M25 at Junction 24.
- The building between Cockfosters Road and the railway used to be offices, but it is now being converted into housing.
That high roof of the housing development, must be an ideal candidate for solar panels and vertical wind turbines.
Conclusion
I have tried to show the potential of just one of the small hills that ring London.
The Ultimate Bus Stop
London has very comprehensive bus stops as these pictures show.
Note.
- Most bus stops have a pole mounted roundel, that can be seen from a reasonable distance. In many cases, anybody with reasonable sight can see the roundel for the next stop.
- Where space permits, bus stops have a shelter with seats, maps and instructions on ticketing.
- Some stops have been extended into the road, so that it is a level step into and out of the bus.
- As shown in the pictures, so bus stops have displays showing the next ten buses, that will be arriving.
But I do think, they could be improved, with extra features.
Internet Connectivity
I feel strongly, that all bus stops should have good internet connectivity.
This could be 4G, 5G or just wi-fi, but I believe this could help with the safety of people on the street.
Comprehensive Lighting
To contribute to safety, I also feel that all bus stops should be well lit.
CCTV Issues
I also feel that all bus stops should have provision for CCTV, so if there was a need, it could be quickly fitted. But if the bus stop had good internet connectivity, then this shouldn’t be a problem.
Phone Charging
New buses have this feature, so why not at the stops?
Power Supply Issues
If we add all these features, we could be needed an uprated power supply.
- So could we see bus stops, with solar panels on the roof.
- Perhaps even a mini wind turbine?
- I think a vertical wind turbine, which was similar to a SeaTwirl, but smaller, could be ideal!
- Could it be called a StreeTwirl?
- A self-powered bus could be created with the addition of a battery.
Self-powered bus stops might be easier to install.
Conclusion
Bus stops will have more features in the future.
