UK Breakthrough Could Slash Emissions From Cement
The title of this post. is the same as that of this article on the BBC.
This is the sub-heading.
Scientists say they’ve found a way to recycle cement from demolished concrete buildings.
These five paragraphs outline, why cement is such an environmental problem.
Cement is the modern world’s most common construction material, but it is also a huge source of planet-warming gas emissions.
That is because of the chemical reactions when you heat limestone to high temperatures by burning fossil fuels.
Recycling cement would massively reduce its carbon footprint. Researchers say that if they switched to electric-powered furnaces, and used renewable energy like wind and solar rather than fossil fuels, that could mean no greenhouse gases would be released at all.
And that would be a big deal. Cement forms the foundation of the modern economy, both literally and metaphorically.
It is what binds the sand and aggregate in concrete together, and concrete is the most widely used material on the planet after water.
If cement was a country, it would be the third biggest source of emissions after China and the US, responsible for 7.5% of human-made CO2.
This article shows how by applying chemical magic to two effectively unrelated processes; the recycling of steel and the recycling of concrete to make new cement, very high rewards are possible.
Cambridge University are calling their new product electric cement.
As large amounts of electricity are used in an arc furnace, to produce the two products
These paragraphs outline the innovative Cambridge process.
Cement is made by heating limestone to up 1600 Celsius in giant kilns powered by fossil fuels.
Those emissions are just the start. The heat is used to drive carbon dioxide from the limestone, leaving a residue of cement.
Add both these sources of pollution together and it is estimated that about a tonne of carbon dioxide is produced for every tonne of cement.
The team of scientists,, has found a neat way to sidestep those emissions.
It exploits the fact that you can reactivate used cement by exposing it to high temperatures again.
The chemistry is well-established, and it has been done at scale in cement kilns.
The breakthrough is to prove it can be done by piggybacking on the heat generated by another heavy industry – steel recycling.
When you recycle steel, you add chemicals that float on the surface of the molten metal to prevent it reacting with the air and creating impurities. This is known as slag.
The Cambridge team spotted the composition of used cement is almost exactly the same as the slag used in electric arc furnaces.
They have been trialling the process at a small-scale electric arc furnace at the Materials Processing Institute in Middlesbrough.
These are my thoughts.
The Only Inputs Are Steel Scrap, Green Electricity And Used Cement
Consider.
- We probably need to increase the percentage of steel scrap we collect.
- Gigawatts of green electricity in a few years, will be available in those places like Port of Ardersier, Port Talbot, Scunthorpe and Teesside, where large amounts of steel will be needed.
- I can envisage large steel users having their own hybrid electric cement/electric arc furnace plants.
- Used cement would be collected and brought to the plants.
- Years ago, I used to live next door to an old World War II airfield. The farmer who owned the airfield, told me, that the concrete was his pension, as when he needed money, he called a company, who crushed it up for aggregate.
I can see a whole new integrated industry being created.
Conclusion
This could be one of the best inventions since sliced bread.
An Early General Election
One thing that worries me about an early election, is it gives Putin less time to plan and execute his dirty work.
So he might do something a lot more extreme!
So make sure your cybersecurity is up to date!
First US Hydrogen-Fueled Ferry Okayed For Commercial Operation
The title of this post, is the same as this of this article on OffshoreEnergy.biz.
This is the sub-heading.
US-based shipping company SWITCH Maritime has received approval from the U.S. Coast Guard for its hydrogen-powered ferry Sea Change to enter commercial operations.
This is the first paragraph.
As informed, the company was presented with the signed Certificate of Inspection (COI) by Captain Taylor Q. Lam, the U.S. Coast Guard Sector San Francisco commander and Captain of the Port, for its flagship hydrogen ferry.
This paragraph gives more details of the ferry.
Built and launched at All American Marine shipyard in Bellingham, Washington, Sea Change is a 75-passenger catamaran ferry featuring an integrated hydrogen power system from Zero Emission Industries (ZEI), with 360kW of fuel cells from Cummins and 600kW of electric motor propulsion from BAE Systems.
As the electric motor propulsion is 600 kW and there are only 360 kW of hydrogen fuel cells, I suspect there is a battery in there somewhere.
The Orkney Islands have their own hydrogen ferry project called HySeasIII.
The Orkney ferry uses 600 kW of Ballard fuel cells.
There is no news this year about what is happening to the Orkney project.
Redevelopment Of Scottish Port Begins As Owner Secures GBP 400 Million For Offshore Wind Upgrade
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Haventus, the owner of the Ardersier Port in the Moray Firth, Scotland, has taken a final investment decision and kicked off construction work on redeveloping the port to serve both fixed-bottom and floating offshore wind projects. The revamped port is expected to open in the second half of 2025.
These are the first two paragraphs.
This month, Haventus was granted a GBP 100 million (approximately 117 million) joint credit facility from the Scottish National Investment Bank and UK Infrastructure Bank with GBP 50 million (approx. EUR 58.5 million) investment from each.
This follows a GBP 300 million (approx. 351 million) investment commitment by the energy investment firm Quantum Capital Group in 2023 when Haventus began the redevelopment of Ardersier Port.
This page on the Haventus web site, gives more details of the Port of Ardersier.
Included are.
- Access channel width – 160 m.
- Access channel depth – 12.4 m.
- Landside area – 350 acres.
- 420m main quay.
- 80 m Ro/Ro capable berth.
- People-friendly midges
- Green Freeport tax site designation
- More space is available if required.
There is also an informative video.
Haventus say they are delivering a world-leading energy transition facility. I can go along with that!
These are my thoughts.
The Location Of The Port of Ardersier
This Google Map shows the location of the Port of Ardersier.
Note.
- The large expanse of water in the middle of the map is Moray Firth.
- The blue arrow at the bottom of the map indicates Inverness Airport.
- Inverness Airport, has a railway station on the Aberdeen and Inverness Line.
- The village of Ardersier is on the the Eastern bank of the Moray Firth
- The Port of Ardersier is in the North-East corner of the map.
The city of Inverness, with a population of around 48,000, is a few miles South-West of the South-West corner of the map.
Which Windfarms Will Be Built And Serviced From The Port Of Ardersier?
This map shows the various ScotWind leases, around the North of Scotland.
The numbers are Scotwind’s lease number in their documents.
These are the Scotwind wind farms to the North-East of Scotland, that could reasonably be assumed to be built and served from the Port of Ardersier.
- 7 – DEME Concessions Wind – 200 km² – 1.0 GW – Floating
- 8 – Falck Renewables Wind – 256 km² – 1.0 GW – Floating
- 9 – Ocean Winds – 429 km² – 1.0 GW – Fixed
- 10 – Falck Renewables Wind – 134 km² – 0.5 GW – Floating
- 11 – Scottish Power Renewables – 684 km² – 3.0 GW – Floating
- 12 – BayWa r.e. UK – 330 km² – 1.0 GW – Floating
These are the Scotwind wind farms to the North-West of Scotland, that could reasonably be assumed to be built and served from the Port of Ardersier.
- 13 – Offshore Wind Power – 657 km² – 2.0 GW – Fixed or Floating
- 14 – Northland Power – 390 km² – 1.5 GW – Floating
- 15 – Magnora – 103 km² – 0.5 GW – Floating
- 16 – Northland Power – 161 km² – 0.8 GW – Floating
These ten wind farms add up to 12.3 GW.
Transport
Consider.
- Obviously, heavy components will be brought in by sea, using the Ro/Ro capable berth or using a crane to unload a barge.
- Personnel will be able to fly in for the day.
- Will some visitors rom London use the Caledonian Sleeper to and from Inverness station to get a full day on site and a good night’s sleep, whilst travelling.
But I do see a problem with local traffic to and from the site.
Hydrogen Buses
This page on the Sizewell C web site, discusses how they will use hydrogen buses.
I could see the Port of Ardersier taking a leaf out of Sizewell C’s book and run hydrogen buses to Inverness, Inverness Airport and other nearby towns.
The North of Scotland certainly won’t be short of green hydrogen to power the buses.
Hydrogen
Conclusion
If you thought that the only useful wind-driven thing to come out of Scotland was bagpipes, you had better think again.
The Port of Ardersier will be the factory and operation and maintenance port for one of the largest offshore wind industries in the world.
Dr. David Owen And The NHS Infected Blood Scandal
I am writing this post, mainly using Dr. David Owen’s Wikipedia entry.
This paragraph describes Dr. Owen’s early days as a minister in Harold Wilson’s first government and the early days of Harold Wilson’s second government
From 1968 to 1970, Owen served as Parliamentary Under Secretary of State for the Navy in Harold Wilson’s first government. After Labour’s defeat in the 1970 general election, he became the party’s Junior Defence Spokesman until 1972 when he resigned with Roy Jenkins over Labour’s opposition to the European Community. On Labour’s return to government in March 1974, he became Parliamentary Under-Secretary for Health before being promoted to Minister of State for Health in July 1974.
There is also this paragraph describing his involvement as Minister of State for Health in the NHS Infected Blood Scandal.
As Minister of State for Health he encouraged Britain to become “self-sufficient” in blood products such as Factor VIII, a recommendation also promoted by the World Health Organisation. This was principally due to the risk of Hepatitis infection from high-risk blood donors overseas who were often paid and from “skid-row” locations. David Owen has been outspoken that his policy of “Self-Sufficiency” was not put into place (although he was, himself, Minister of Health) and gave rise to the Tainted Blood Scandal which saw 5,000 British Haemophiliacs infected with Hepatitis C, 1,200 of those were also infected with HIV. It was later described in the House of Lords as “the worst treatment disaster in the history of the National Health Service”.
So why did Dr. Owen’s and the World Health Organisation’s view of making the UK “self-sufficient” in blood products such as Factor VIII not prevail?
Did Sir Brian Langstaff and his team go through minutes of cabinet meetings, when Dr. David Owen was Minister of State for Health?
Did Harold Wilson or the Chancellor; Denis Healey overrule David Owen’s view, as they needed what little money we had for other purposes?
I must admit, that if I had been in Dr. Owen’s position in 1974 and the Government were proposing to something against, my engineering experience, I would have resigned. Note that Dr. Owen did resign in 1972, over Labour’s opposition to the European Community.
If any doctors are reading this, who were qualified at the time, I’d like to hear their views.
Conclusion
One way to ascertain the truth, would be to charge Dr. Owen with something serious and led the Law decide.
Thoughts On The NHS Infected Blood Scandal
In the early 1970s, I was working with the Chief Management Accountant of a retail bank, writing a computer system to analyse and compare the performance and costs of all their branches.
We used scatter diagrams and other graphical techniques to show all the branches on single sheets produced by line printers on a powerful time-shared computer. It would be so much easier today.
Any branch not following the rules was often found sitting alone away from the mass of branches on the graphs.
I remember one branch had costs, that were much higher than expected. It turned out it was the Stevenage Branch, where the premises were rented rather than owned freehold.
Expanding The System To Other Industries
The Accountant, who had also been Chief Accountant of a FTSE 500 company, felt that the techniques we had developed had other applications in the management and auditing of large companies and organisations.
Sadly my partner in crime, died of cancer and I went on to other things.
From my own generally good family experiences of the NHS, I feel that this sort of analysis used rigorously could give early warning of some of the scandals we’ve seen in the NHS.
Around the turn of the century, I used similar techniques to improve the manufacturing quality in a diesel engine factory.
Conclusion
Perhaps we need an independent Office of NHS Responsibility?
Fifth Hydro Project Proposed At Loch Ness
The title of this post. is the same as that of this article on the BBC.
This is the sub-heading.
The local community is to be asked for its views next week on plans for a new hydro-electric scheme at Loch Ness.
These three paragraphs introduce the new scheme.
Glen Earrach Energy’s, external (GEE) pumped storage hydro project is the fifth hydro scheme proposed for the Loch Ness area.
The company said its project on Balmacaan Estate would create clean energy while protecting the environment, and create 600 on-site jobs.
But concerns have been raised about the number of planned schemes, with Ness District Salmon Fishery Board worried about the effect on wild fish.
The project has a web site, which has a section entitled About The Project, where this is said.
Glen Earrach Energy, which means “Valley of Spring” in Gaelic, stands at the forefront of energy innovation. The Pumped Storage Hydro (PSH) project, located at Balmacaan Estate, Scotland, is a critical component for achieving a net-zero grid by 2030.
The project prioritises environmental preservation and biodiversity enhancement while achieving outstanding efficiency in energy storage and generation.
This ensures a healthier and more sustainable balance between harnessing natural energy resources and the maintenance and reinforcement of the surrounding ecosystem.
Note.
- It doesn’t say, but it looks like Glen Earrach Energy aim to complete the project by 2030.
- Glen Earrach Energy also seem to be playing a strong environmental card.
But nothing is said about the size of the project.
This article on Business Insider, which is entitled £3 billion Loch Ness Hydro Project Plans Unveiled, does give some details.
- Potential Investment – More than £2 billion
- Output – 2 GW
- Storage Capacity – 30 GWh
- The project could create at least 600 on-site construction jobs in Scotland over a six-year period, plus many thousands more locally in the supply chain.
It is larger, than SSE’s flagship Coire Glas pumped storage hydroelectric power station, which is planned to be a 1.5 GW/30 GWh station, at the other end of the Great Glen.
I have some thoughts.
The Existing Hydro Schemes On Loch Ness
According to the BBC article, there are two existing hydro schemes on Loch Ness.
- Foyers is described on this web site and is a reasonably modern 305 MW/6.3 GWh pumped storage hydroelectric power station, that was built by SSE Renewables in the last fifty years.
- Glendoe is described on this web site and is a modern 106.5 MW conventional hydroelectric power station, that was built by SSE Renewables in the last twenty years.
Foyers and Glendoe may not be the biggest hydroelectric power stations, but they’re up there in size with most solar and onshore wind farms. Perhaps we should look for sites to develop 100 MW hydroelectric power stations?
The Proposed Hydro Schemes On Loch Ness
According to the BBC article, there are four proposed hydro schemes on Loch Ness.
- Coire Glas is described on this web site and will be a 1.5GW/30 GWh pumped storage hydroelectric power station, that is being developed by SSE Renewables.
- Fearna is described on this web site and will be a 1.8GW/37 GWh pumped storage hydroelectric power station, that is being developed by Gilkes Energy.
- Loch Kemp is described on this web site and will be a 600MW/9 GWh pumped storage hydroelectric power station, that is being developed by Statera.
- Loch Na Cathrach is described on this web site and will be a 450MW/2.8 GWh pumped storage hydroelectric power station, that is being developed by Statktaft.
In addition there is, there is the recently announced Glen Earrach.
- Glen Earrach is described on this web site and will be a 2GW/30 GWh pumped storage hydroelectric power station, that is being developed by Glen Earrach Energy.
Note.
- The total power of the seven pumped storage hydroelectric power stations is 4.76 GW.
- The total storage capacity is 85.1 GWh.
The storage capacity is enough to run all turbines flat out for nearly five hours.
Could Glendoe Be Updated To Pumped Storage?
The Wikipedia entry for the Glendoe Hydro Scheme mentions pumped storage several times.
In Glendoe Hydro Power Station, I estimate that a Glendoe pumped storage scheme could be perhaps 50 % bigger than the system at Foyers.
I feel that if more storage capacity is needed in the Highlands, then Glendoe could be converted to pumped storage.
FirstGroup’s Lumo Seeks To Launch Rochdale – London Open Access Service
The title of this post, is the same as that of this article on Railway Gazette.
These two paragraphs outline the service.
FirstGroup has applied to operate Rochdale – London open access passenger trains, more than 20 years after a short-lived through service ran between the two destinations.
On May 17 FirstGroup said that it had applied to the Office of Rail & Road to launch six Lumo-branded return journeys per day linking London Euston and Rochdale via the West Coast Main Line. The trains would call at Warrington Bank Quay, Newton-le-Willows, Eccles and Manchester Victoria.
These are my thoughts.
The Route Isn’t Fully-Electrified
The route is electrified between London Euston and Manchester Victoria stations, but the 10.4 miles between Manchester Victoria and Rochdale is not electrified.
In Extra Luggage Racks For Lumo, I also talk about the possibility of fitting traction batteries to Lumo’s Class 803 trains, so they could handle the 88.5 mile diversion on the East Coast Main Line via Lincoln.
Trains with a traction battery, with an 88.5 mile range, would be able to travel between Manchester Victoria and Rochdale and return.
How Long Would London Euston And Rochdale Take?
Consider.
- The fastest London Euston and Warrington Bank Quay services take 1 hour and 44 minutes
- The fastest Warrington Bank Quay and London Euston services take 1 hour and 47 minutes
- Northern’s Class 195 trains take between 44-51 minutes Rochdale and Warrington Bank Quay with three stops.
- Northern’s Class 195 trains take between 29-32 minutes Manchester Victoria and Warrington Bank Quay with two stops.
- I will add two minutes for the extra stop.
These are my estimates for overall journey times.
- London Euston and Manchester Victoria – 2 hours and 15 minutes
- London Euston and Rochdale – 2 hours and 29 minutes
- Manchester Victoria and London Euston – 2 hours and 21 minutes
- Rochdale and London Euston – 2 hours and 40 minutes
The fastest direct Avanti West Coast services between London Euston and Manchester Piccadilly take 2 hours and 6 minutes.
Could The Service Be Extended To Leeds?
For my timings between Rochdale and Warrington Bank Quay, I used Northern’s Leeds and Chester service.
This service goes between Manchester Victoria and Leeds calling at Rochdale, Todmorden, Hebden Bridge, Halifax, Bradford Interchange, New Pudsey and Bramley.
I estimate it would take about 3 hours 32 minutes.
When Bradford has a new through station, I wouldn’t be surprised if a train operator looked at this route between London Euston and Leeds.
As Leeds and Manchester Victoria is only 49.8 miles, Lumo’s battery electric trains, with 88.5 mile batteries sized for the Lincoln diversion on the East Coast Main Line, would have no difficulty serving Leeds, where they would charge before return.
Could Lumo Run Pairs Of Five-Car Trains Between London Euston and Manchester Victoria?
As I said in Ten-Car Hull Trains, Lumo’s sister company; Hull Trains, runs the occasional ten-car service.
Perhaps for a big football match or other event, Lumo might like to run ten-car trains between Manchester Victoria and London Euston.
I suspect they could do it if the platforms were long enough, but they wouldn’t be able to run a 260 metre ten-car train to Rochdale, as that station only has a 135 metre long platform.
Warrington Bank Quay Station Will Get Six Extra Non-Stop Trains To And From London
This would provide real competition to Avanti West Coast over this route.
Newton-le-Willows Station Is Only A Few Miles From The Town Of St. Helen’s
Newton-le-Willows station has 400 parking spaces and 32 disabled parking spaces.
Note.
- The parking is all free!
- There are regular local trains to Chester, Leeds, Liverpool Lime Street, Manchester Airport and Wigan North Western.
A six trains-per-day service to and from London, will help fill up the parking spaces.
Eccles Station Is Within Walking Distance Of Eccles Interchange
This OpenRailwayMap shows Eccles station and Eccles Interchange.
Note.
- The mauve tracks are the Manchester Metrolink.
- They terminate in the South-West at Eccles Interchange.
- The red tracks are the Liverpool-Manchester lines.
- Eccles station is a Northerly walk from Eccles Interchange.
This connection must be useful to more than a few.
I suspect if you’re going between London and Media City UK, Salford Quays or Piccadilly Gardens, you may be better to change to the Metrolink at Eccles.
Will Lumo’s Rochdale Service Run As A Flight With Avanti’s Glasgow Service?
Flighting is where two or more trains going on the same route run a few minutes apart.
- Every hour, on the half hour, an Avanti West Coast service for leaves London Euston for Glasgow Central.
- As with Lumo’s Rochdale service, the first stop is Warrington Bank Quay station.
- The Lumo service would leave London Euston a few minutes after Avanti’s Glasgow service.
- The distance between the two trains would be such, that if the first train stopped, the second train could stop safely.
- Digital signalling as is being installed on UK rail lines would make it easier to ensure safe separation.
But the benefit would be that both trains ran fast to Warrington Bank Quay station.
A Day-Trip To Manchester
If I’m right about the 2 hours and 15-21 minutes between London Euston and Manchester Victoria, then a day-trip would certainly be feasible.
Last Trains
This is a table of the last train times for Lumo between Newcastle and London.
- Weekdays – 20:27 21:35
- Saturdays – 18:27 19:22
- Sundays – 19:24 20:21
Note.
- The first time is the last Northbound departure.
- The second time is the last Southbound departure.
- Are these late enough for football matches?
I shall be interested to see the proposed last train times for the Manchester route.
- Will they be timed so you can get a tram from the Etihad or Old Trafford stadium after an evening match, that allowed you to get the last train back to London from Manchester Victoria?
- Taylor Swift gave the Manchester Arena a lot of favours with her concerts. Would you have been able to see her concert and get the last train back to London?
A few extra full trains wouldn’t hurt Lumo’s finances.
Conclusion
It looks like, this could be a very worthwhile service.
It’s All Happening In Jamshedpur!
When I read this article on Hydrogen Fuel News, which is entitled Cummins And Tata Motors Ignite Change With H2 Internal Combustion Engines, I couldn’t resist using the jokey headline, which was inspired by the sub-heading.
The manufacturing has started in Jamshedpur, India at a new state-of-the-art facility
These two paragraphs give some more details.
The hydrogen internal combustion engines continuing to be produced at the facility are being integrated into Tata Motors trucks. This technology is being viewed as a promising zero- or low-carbon alternative to diesel power because of its powerful performance and substantial operating range.
Cummins’ B6.7H engines have notable similarities to current natural gas and diesel engines, particularly in terms of the components they contain. Moreover, they can fit in standard engine vehicles and require similar refueling times.
I first wrote about the Cummins B 6.7H engines in Cummins Shows Hydrogen Internal Combustion-Engined Concept Truck At IAA Transportation Exhibition, which I posted in September 2022.
I have these further thoughts.
Cummins B Series Engine
The Wikipedia entry for the Cummins B Series Engine, starts with these two paragraphs.
The Cummins B Series is a family of diesel engines produced by American manufacturer Cummins. In production since 1984, the B series engine family is intended for multiple applications on and off-highway, light-duty, and medium-duty. In the automotive industry, it is best known for its use in school buses, public service buses (most commonly the Dennis Dart and the Alexander Dennis Enviro400) in the United Kingdom, and Dodge/Ram pickup trucks.
Since its introduction, three generations of the B series engine have been produced, offered in both inline-four and inline-six configurations in multiple displacements.
Note.
- Cummins B Series is used in a wide variety of vehicles.
- It is available in both four and six cylinder versions.
But what Wikipedia doesn’t say, is that any Cummins’ customer will get the engine he wants for his application, even if it means creating a special version of the engine. Thirty years ago, I did a small data analysis job for Cummins in Darlington and on a tour of the works, I was given full details on how they treated customers. Cummins are not your average US company.
London’s Routemaster Buses
These buses are powered by a small four-cylinder version of the B-series engine, called a 4.5L ISB, which is described like this in Wikipedia.
The 4.5L ISB is essentially a four-cylinder, two-thirds version of the 6.7L ISB rated at 185 hp (138 kW), used in the New Routemaster, a series hybrid diesel-electric double-decker bus in London.
Note.
- Some diesel Range-Rovers, have more power, than these buses, but then they’re not hybrids.
- The engine also needs to be smaller, as it’s mounted under the back stairs.
Did Cummins’ special engine. allow the unique design of London’s Routemaster Buses?
Could London’s Routemaster Buses Be Converted To Hydrogen?
As an engineer and with my knowledge of Cummins’ design and manufacturing methods, I am fairly certain, if Cummins can manufacture six-cylinder versions of the B-Series engines, then four-cylinder hydrogen-powered engines are not far behind.
If London were to convert the thousand New Routemaster buses to hydrogen, there would be winners all round.
- Cummins would love the publicity and would probably benefit from increased sales of their hydrogen engines in vehicles like refuse trucks and small buses.
- It would surely give a route to convert older vehicles to hydrogen.
- The air in cities will improve.
But London has a problem, It is one of the few large cities in the world without readily-available hydrogen.
As this post illustrates and my Google searches show, India has a more advanced and scientifically-correct view on the usefulness of hydrogen.
Will Jaguar Land Rover Switch To Cummins’ Hydrogen Engines?
If Tata Motors make a success of hydrogen in India, it must make them think about adding hydrogen engines to Jaguar Land Rover products, specially as other manufacturers are getting serious about hydrogen.
Conclusion
Cummins will change the world for the better.
