The Versatile Substance That Is Carbon Black
I suspect very few of us think much about carbon black.
In an over fifty-year working life, I have only come across carbon black indirectly and no-one has actually shown me any carbon black.
This is the first sentence of the Wikipedia entry for carbon black.
Carbon black (with subtypes acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal tar, vegetable matter, or petroleum products, including fuel oil, fluid catalytic cracking tar, and ethylene cracking in a limited supply of air.
It doesn’t sound the most appetising of substances and the next sentence reinforces that view.
Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) polycyclic aromatic hydrocarbon (PAH) content.
The text is illustrated with what looks like a small pile of soot.
I first came across carbon black, in my first job after leaving Liverpool University at ICI Mond Division at Runcorn.
For a time, I shared an office with Peter, who was part of a number of engineers, who were trying to get a new plant, that had been purchased from BASF to make commercial quantities of acetylene. All the plant seemed to make was large quantities of soot, which it then proceeded to spread all over the town of Runcorn.
If I remember correctly, the process worked by burning ethylene in a limited supply of air and then quenching it with naphtha. The similarities between the BASF process and the method for producing carbon black lead me to believe, that ICI’s process was probably producing a lot of carbon black.
Peter was working on an instrument that measured the quantity of acetylene in the off-gas from the burners and he succeeded, but unfortunately proved that the plant was going into explosive limits. For this reason, ICI shut their process, although BASF persevered.
Ethylene is a hydrocarbon which has the formula C2H4 or two carbon and four hydrogen atoms. So if you can get them to stop tightly holding hands with no oxygen around, the hydrogen will pair off as H2 and the carbon will exist as a lot of single C atoms or carbon black.
BASF and ICI were trying to produce acetylene or C2H2, where there is a powerful triple bond between the two carbon atoms. All that energy in the acetylene makes it useful for activities like welding.
Common Uses Of Carbon Black
The Wikipedia entry for carbon black, has this summary of its uses.
The most common use (70%) of carbon black is as a pigment and reinforcing phase in automobile tires. Carbon black also helps conduct heat away from the tread and belt area of the tire, reducing thermal damage and increasing tire life. Its low cost makes it a common addition to cathodes and anodes and is considered a safe replacement to lithium metal in lithium-ion batteries. About 20% of world production goes into belts, hoses, and other non-tire rubber goods. The remaining 10% use of carbon black comes from pigment in inks, coatings, and plastics, as well as being used as a conductive additive in lithium-ion batteries.
The entry then gives a list of other uses, some of which are still being developed.
Global Production Of Carbon Black
This paragraph is from the Wikipedia entry for carbon black.
Total production was around 8,100,000 metric tons (8,900,000 short tons) in 2006. Global consumption of carbon black, estimated at 13.2 million metric tons, valued at US$13.7 billion, in 2015, is expected to reach 13.9 million metric tons, valued at US$14.4 billion in 2016.
So we have the useful paradox, that we don’t want to emit more carbon dioxide, but extra carbon black could probably be usefully used.
Conclusion
Using the HiiROC process to extract hydrogen could even give us a biproduct ; carbon black, that has uses.
Regulator Approves New Go-op Train Service Between Swindon, Taunton and Weston-super-Mare
The title of this post, is the same as that of this press release from the Office of Rail and Road.
This is the sub-heading.
The rail regulator has given the go ahead for new train services between Swindon, Taunton and Weston-super-Mare from the end of 2025. The regulator has also set conditions on its approval to ensure the new, co-operatively owned operator has sufficient finance and rolling stock in place in good time.
These paragraphs from the press release give more details.
Go-op plans to operate return weekday and weekend services between Taunton and Weston-super-Mare, Taunton and Westbury, Taunton and Swindon, and Frome and Westbury.
It will compete with Great Western Railway (GWR), a public service operator. Go-op plans to start in December 2025 at the earliest, and must do so no later than December 2026 in order to use the capacity ORR has granted.
As part of ORR’s decision, Go-op must provide evidence to ORR of the necessary finance to start operations, fund level crossing enhancements, and that the necessary rolling stock has been secured. ORR’s decision requires Go-op to do this without delay, and no later than November 2025.
I must admit I’m a little surprised at the Office of Rail and Road giving approval.
There is more on the Go-op web site.
London’s New Tram-Like Buses Come Into Service
The title of this post, is the same as that of this article on the BBC.
I went to Orpington station and all I saw was several small diesel single-decker buses running around in the awful cold.
So I retreated on a warm train after a couple of hours.
One driver said that the reams were running and she looked genuinely disappointed, that they hadn’t turned up.
But from my knowledge of electric vehicles, although not Irizar ie Trams, I do wonder if the single-figure temperatures in Orpington had drained the batteries.
But I can’t imagine a company like Irizar making a mistake like that.
Although one of the station men said that Orpington can get to be a very cold station. Now that is something I’ll agree with!
In the other hand the 358 route takes an hour from end to end, so in my opinion, it might have been better to use hydrogen-powered buses.
Bord Gáis Energy Acquires Leading Irish Solar PV Installer Swyft Energy
The title of this post, is the same as that of this news item from Centrica.
This is the sub-heading.
Bord Gáis Energy today announced the acquisition of Swyft Energy, a leading solar PV provider in Ireland for an undisclosed sum.
Note.
- Bord Gáis Energy is a subsidiary of Centrica.
- Swyft Energy has this web site.
These three paragraphs give more details of the acquisition.
Bord Gáis Energy already operates in the solar PV market: directly to residential customers, and through its partnership with Irish Farmer’s Association delivering solar PV to farms across Ireland, helping farmers transition to green energy. The acquisition of Swyft Energy now brings deeper solar PV capability to residential as well as business and farming customers of Bord Gáis Energy, as the company transitions to a green energy business.
Swyft Energy, a technology-led solar PV and boiler installation company, brings over six years of experience in delivering customer-focused solutions using a digital-first platform. This acquisition enhances Bord Gáis Energy’s highly skilled workforce and strengthens its customer proposition.
With a target of 10,000 installations over the next 5 years, this will allow Bord Gáis Energy to compete better for the growing demand for solar energy in residential, commercial and agricultural sectors. Customers can save an average of 50-70% on their electricity bills with the installation of rooftop solar panels.
The deal certainly looks a good fit between two ambitious companies, who are operating in similar areas of the Irish market.
I have my thoughts and observations.
Are Bord Gáis Energy And Swyft Energy Stronger Together?
Do both companies feel, that by working together, they will be stronger from a financial point of view?
It wouldn’t be unusual for this to be a reason behind a deal like this.
Centrica Are Making Lots Of Deals At The Present Time
Centrica are also continuing, the tendency to expand, that they’ve shown in recent weeks.
These are some of the deals I have noted.
- Aberdeen’s Exceed Secures Centrica Rough Contract
- HiiROC Partners With Siemens To Boost Clean Hydrogen Production
- Centrica Strikes 200MW Lithuanian Green Power Deal
- Centrica And Coterra Energy Announce Natural Gas Sale And Purchase Agreements
- Centrica And European Energy Sign Agreement On Måde Green Hydrogen Facility
- Recurrent Energy’s Middle Road Project Sold To Centrica
- Team GB And ParalympicsGB Athletes Find New Career Pathway At Centrica
- UK Infrastructure Bank, Centrica & Partners Invest £300M in Highview Power Clean Energy Storage Programme To Boost UK’s Energy Security
Centrica certainly have been busy expanding.
Energy Storage In The Island Of Ireland
It is generally accepted, that if you have a lot of renewable energy, then you need a lot of energy storage, to bridge the gaps in wind and solar.
In the Wikipedia entry for Energy In Ireland, there is a section called Energy Storage.
It seems to me, that Ireland could be short on energy storage, so is it likely that the enlarged Bord Gáis Energy will look for possibilities for energy storage.
Recently, Centrica formed a business relationship with Highview Power, who are developing environmentally-friendly liquid-air batteries. These smaller and more affordable batteries might be suitable for the island of Ireland.
Conclusion
There’s more to this deal, than at first meets the eye.
First Commercial-Scale Seaweed Farm Between Wind Turbines Fully Operational In Netherlands
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The world’s first commercial-scale seaweed farm within the Hollandse Kust Zuid offshore wind farm in the Netherlands is fully operational.
These initial three paragraphs fill out the details.
According to the non-profit organisation North Sea Farmers (NSF), the final deployment step was completed one week ago by deploying the seeded substrate.
North Sea Farm 1, initiated by NSF with funding from Amazon’s Right Now Climate Fund, is a floating farm located in the open space between wind turbines where seaweed production can be tested and improved.
The seaweed farm is located within the Hollandse Kust Zuid wind farm, nearly 22 kilometres off the coast of Scheveningen. The 1.5 GW project is owned by Vattenfall, BASF, and Allianz.
I find this an interesting concept.
I can remember reading in the Meccano Magazine in the 1950s, about the production of alginates from seaweed in Scotland.
Surprisingly, Wikipedia has very little on alginates, except for this illuminating Wikipedia entry for alginic acid.
This is the opening paragraph.
Alginic acid, also called algin, is a naturally occurring, edible polysaccharide found in brown algae. It is hydrophilic and forms a viscous gum when hydrated. When the alginic acid binds with sodium and calcium ions, the resulting salts are known as alginates. Its colour ranges from white to yellowish-brown. It is sold in filamentous, granular, or powdered forms.
But it does appear that the Scottish production of alginates is very much of the past. Unless someone else can enlighten me!
Perhaps Scottish seaweed farming can be revived to produce alginates, which appear to have a surprising number of uses, as this section of the Wikipedia entry shows.
Alginates do appear to be remarkably useful.
These are a few uses.
- As of 2022 alginate had become one of the most preferred materials as an abundant natural biopolymer.
- Sodium alginate is mixed with soybean protein to make meat analogue.
- They are an ingredient of Gaviscon and other pharmaceuticals.
- Sodium alginate is used as an impression-making material in dentistry, prosthetics, lifecasting, and for creating positives for small-scale casting.
- Sodium alginate is used in reactive dye printing and as a thickener for reactive dyes in textile screen-printing.
- Calcium alginate is used in different types of medical products, including skin wound dressings to promote healing,
Alginates seem to have some rather useful properties.
Four years ago, I tripped over in my bedroom, which I wrote about in An Accident In My Bedroom. I wonder if the Royal London Hospital used calcium alginate skin dressings to restore my hand to its current condition.
Paul Daniels would have said, “It’s magic!”
In the future these dressings may be produced from UK-produced seaweed.
Marks & Spencer Get A Bit Cheeky
I bought these strawberries in Marks and Spencer on Moorgate, yesterday.
Note.
- They have a Best Before Date of Thursday.
- They were grown in West Sussex by the Summer Berry Co.
But I do think it is a bit cheeky to label them with a yellow label saying “New Season”!
Their web site gives a few answers.
Islington Socialism At Work
This picture illustrates the terrible state of Islington’s pavements.
I had just got off the 141 bus, that is pulling away from the bus stop in the picture.
Despite wearing boots, I nearly fell flat on my face because of the very wet weather and all the leaves.
Note that on the other side of the road, Hackney’s pavements are in much better state, being level and clear of leaves.
Sort your side of the road out, Islington!
Lakeside Facility Connects To Grid And Becomes UK’s Largest Transmission Connected Battery
The title of this post, is the same as that of this press release from National Grid.
These three bullet points, act as sub-headings.
- National Grid plugs TagEnergy’s 100MW battery project in at its Drax substation.
- Following energisation, the facility in North Yorkshire is the UK’s largest transmission connected battery energy storage system (BESS).
- The facility is supporting Britain’s clean energy transition, and helping to ensure secure operation of the electricity system.
This paragraph introduces the project.
A battery storage project developed by TagEnergy is now connected and energised on the electricity transmission network, following work by National Grid to plug the facility into its 132kV Drax substation in North Yorkshire.
- Lakeside Energy Park’s 100MW/200MWh facility is now the largest transmission connected BESS project in the UK following energisation.
- The new facility will boost the capacity and flexibility of the network, helping to balance the system by soaking up surplus clean electricity and discharging it back when the grid needs it.
- To ensure a safe connection, National Grid, working with its contractor Omexom, upgraded its Drax 132kV substation to accommodate the additional clean power.
- Works included extending the busbars – which enable power flows from generation source on to power lines – upgrading busbar protection and substation control systems, and installing an operational tripping scheme, all of which helps keep the network stable and operating securely.
Owned and operated by TagEnergy – with Tesla, Habitat Energy and RES as project partners – the newly-connected battery will help exploit the clean electricity potential of renewable projects in the region, storing and releasing green energy to power homes and businesses and also helping to relieve any system constraints.
National Grid’s adjacent Drax 400kV substation already hosts the connection for Drax power station – the UK’s largest biomass facility – and will also connect the Eastern Green Link 2 electrical superhighway when it starts importing clean energy from Scotland in 2029.
Drax power station seems to be growing into a large node with several gigawatts of electricity, the UK’s largest BESS, a large biomass power station and the Eastern Green Link 2 electrical superhighway which will import clean energy from Scotland from 2029.
Drax appears to be transforming from the dirty man of the UK into a Jolly Green Giant.
I can see further power stations and sources, storage devices and technology joining the party at Drax.
This Google Map shows the Drax site.
Note.
- The cooling towers can be picked out in the South-East quarter of the map.
- The site is rail and road connected, with the River Ouse nearby.
- There is a lot of space.
Surely, Drax would have a big enough space, with a high quality and high capacity electrical connection for Ørsted and Highview Power to put one of their three 200 MW/2.5 GWh batteries, that I talked about in Centrica Business Solutions And Highview Power.
Porterbrook Raises £250m Of New Green Private Placements
The title of this post, is the same as that of this article on Railway Gazette.
This is the sub-heading.
Porterbrook, the UK’s leading rolling stock financier and asset management company, is delighted to announce the successful closing of its £250m Private Placement.
These are the first two paragraphs.
The transaction, which includes existing and new investors, has enabled the company to extend its debt maturity profile at attractive pricing and further diversify its investor base of US, UK and Swiss institutions.
Porterbrook owns a quarter of the national passenger rail fleet, and in recent years has significantly diversified its portfolio including taking ownership of the Long Marston Rail Innovation Centre in Warwickshire, confirming a 49% stake in Brodie Engineering in Kilmarnock, and financing the redevelopment of Bletchley Depot for West Midland Trains.
We must be doing something right on the railways, if US, UK and Swiss institutions are prepared to back them financially.
But then Aviva, who were formerly Norwich Union, backed Greater Anglia’s new Swiss trains.
Conclusion
Despite what some might think, it would appear that green investments aren’t all bad.
Ill Wind For Renewable Energy In US To Boost UK Projects
The title of this post, is the same as that of this article on The Times.
This is the sub-heading.
SSE boss Alistair Phillips-Davies says Trump is expected to put oil and gas ahead of renewables, easing supply chain shortages for UK wind power shortages
These are the first two paragraphs.
A likely push towards more oil and gas drilling under President Trump could help ease supply chain shortages that have hampered a faster rollout of renewables on the UK system, but weaken the availability of parts for gas-fired plants, the boss of electricity supplier SSE has said.
Donald Trump’s election win is expected to boost the American oil and gas industries and diminish the buildout of renewables, which had been accelerated by President Biden’s $369 billion stimulus package for clean power and transport.
SSE’s offshore wind farms under construction or planning in the UK, that are likely to be delivered before the end of Trump’s second term are.
- Dogger Bank A – 1235 MW – GE-Haliade X – 2025
- Dogger Bank B – 1235 MW – GE-Haliade X – 2025
- Dogger Bank C – 1218 MW – GE-Haliade X – 2025
- Dogger Bank D – 1320 MW
- Berwick Bank 4100 MW – 2028
- Seagreen Phase 1A – 500 MW
Note.
- The date is the expected commissioning date.
- GE is an American company, that are heavily into renewables and electrical gubbins to connect them to the grid.
- Trump is unlikely to have much effect on the delivery of Dogger Bank A-C.
- If Trump is stopping US wind farm projects, then if SSE has the finance, they will surely be able to take advantage of a lack of turbine orders.
- If you could handle a 4100 MW order, it would keep your company going for at least three years.
Given that SSE are investing billions in renewable energy and because of their past record, I would expect that the SSE boss has called this one right.
