How Hydrogen Will Power The Green Construction Eevolution

The title of this post, is the same as that of this news item from Ryze Hydrogen.

These two paragraphs introduce the news item.

According to the International Energy Agency buildings operations and construction emissions account for more than one-third of global energy-related emissions, significantly contributing to environmental degradation, with heavy machinery and standby power solutions relying heavily on fossil fuels.

Yet here at Ryze we know the industry stands on the brink of a green revolution, as clean energy solutions lead the charge towards decarbonisation.

The news item, is a must-read for anybody involved in construction.

Recently, a gas leak killed the roadside tree outside my house. I wrote about the incident in It Looks Like The Gas Leak Has Killed The Tree Outside My House.

What I didn’t say, was that when they cleaned up the mess, I had an eight-wheeled diesel truck with a grab, working outside my house for a couple of hours, spewing fumes everywhere.

Hopefully, green construction is friendlier to the neighbours and the workers on site.

High Speed Two is using green construction for this reason in sensitive locations.

Waterbeach Station To Be Relocated

The title of this post, is the same as that of this article on Railway Gazette.

These three paragraphs, outline the project.

Cambridgeshire County Council has called tenders for an estimated £35m design and build contract for the relocation of Waterbeach station to a new site further to the north.

This would support the Waterbeach New Town development of 4 500 homes. Opening is now envisaged for 2026.

The replacement station would have two platforms, an accessible footbridge, a 200-space car park, taxi and bus drop-off, cycle storage and a new access road from Cody Road. The 24-month scheme would include the demolition of the existing station.

This Google Map shows the current station and the location of Waterbeach New Town.

Note.

Waterbeach station is at the bottom of the map, just to the right of centre.

  1. The station is on the Breckland Line between Cambridge and Norwich via Ely.
  2. The Breckland Line continues North-East to the North-East corner of the map.
  3. The village of Waterbeach is to the North of the station.
  4. North of Waterbeach is the old Waterbeach Airfield, which will be covered in the housing of the New Town.

Moving the station nearer the New Town would seem to be a sensible action.

I have some further thoughts.

The Remodelling Of Ely

Ely station is a railway bottleneck and in Are The Trains In Ely Finally To Be Sorted?, I discussed what needed to be done.

Would it help, if Waterbeach station were to be rebuilt first?

A Cambridge Metro

Once Waterbeach station has been rebuilt and Cambridge South station has been built, there will be a run of stations through Cambridge.

  • Ely
  • Waterbeach
  • Cambridge North
  • Cambridge
  • Cambridge South

Perhaps, extra trains could be added to create a frequent rail route across Cambridge.

East West Railway

Will the trains of the East West Railway stop at Waterbeach station?

Conclusion

Waterbeach could be a very useful and busy station.

Sizewell C – South Park And Ride

This document on the Planning Inspectorate web site, is a description of the Southern Park and Ride for the Sizewell C Project.

This Google Map shows the area of the Park-and-Ride site.

Note.

  1. Wickham Market is in the South-West corner of the map.
  2. The dual-carriageway is the Wickham Markey by-pass, which is part of the A12 between Ipswich and Lowestoft.
  3. Close to Lower Hacheston is the Northern junction of the by-pass which connects the B1116 and B 1078 roads to the A 12.
  4. If my memory serves me correctly, there is a small roundabout to the North of the A12, where the B 1116 and B 1078 cross, which is referred to as Fiveways Roundabout in some of the documentation.
  5. Wickham Market station is in the South-East corner of the map.

I know the area well, as I used to live less than ten miles to the West of Fiveways roundabout.

This shows the area to the North of Fiveways roundabout to a large scale.

The document on the Planning Inspectorate says this about the site.

The site comprises approximately 26.4 hectares (ha) of predominantly
agricultural land and highway land located north-east of Wickham Market.
The part of the site which would contain the parking and buildings, postal
consolidation building and Traffic Incident Management Area (TIMA) is
approximately 18ha in size, and located to the east of the B1078/B1116, to
the north of the A12. The remainder of the site encompasses a section of
the A12, and an associated slip road where highway improvements are
proposed to form the site access, and associated signage and road
markings, see Chapter 1, Figure 1.1 of this volume.

These are my thoughts.

There Is No Rail Connection

I wrote about the Northern Park-and-Ride in Sizewell C – North Park And Ride and there is one big difference.

The Northern Park-and-Ride is an easy walk from Darsham station.

  • Darsham station has an hourly four-car train to Lowestoft and Ipswich.
  • Some or all trains could be doubled in capacity as Greater Anglia has enough stock to do this.
  • If required, trains could be run to and from London and intermediate stations.
  • In the past, Network Rail have developed plans to extend the service as far as Yarmouth.

I believe that a rail connection at the Southern Park-and-Ride could have added flexibility for workers in Ipswich travelling to the Sizewell site.

Bus Routes

The frequency and timing of park and ride buses would depend on the
working patterns adopted during construction of the Sizewell C main
development site, and the number of workers to be moved during the shift
changeover periods. More frequent services would operate during staff
changeover and shift start/end periods. It is anticipated that there would be
three to nine buses from the proposed development per hour during shift
changeover period, and an hourly service outside shift changeover periods.

There would be a maximum of 100 daily bus arrivals and 100 daily bus
departures from the proposed development to the Sizewell C main
development site. These buses would use the A12, two village bypass and
Sizewell link road once operational to travel to and from the Sizewell C main development site.

This Google Map shows the A 12 between the South Park-and-Ride site and Yoxford.

Note.

  1. Yoxford is in the North-East corner of the map.
  2. Wickham Market is in the South-West corner of the map.
  3. The A 12 is the cream road linking the two villages.
  4. The Southern Park-and-Ride will be to the North-East of Wickham Market.
  5. The Northern Park-and-Ride is a couple of miles North of Yoxford.
  6. Yoxford and Wickham Market are 11.8 miles apart.

This third Google Map shows the route between Yoxford and Sizewell.

Note.

  1. Yoxford is in the North-West corner of the map.
  2. Sizewell is in the South-East corner of the map.
  3. Leiston Abbey is indicated by the arrow to the North of Leiston.

The B 1122 can be picked out through Middleton Moor and Theberton and then as it skirts Leiston Abbey.

It appears that both Park-and-Ride sites, use the same connection between the A 12 and Sizewell C.

Objections To The Park-and-Ride

This petition on change.org is entitled Stop Sizewell C Park and Ride at Wickham Market.

The petitioner is objecting on the following grounds.

  • The size of the site.
  • Spoiling of views.
  • Disturbance to walkers and horse riders.
  • Terrestrial ecology and ornithology will be affected by the site.
  • Increase in traffic.

This was the petitioner’s conclusion.

In conclusion I oppose the Sizewell C southern park and ride site at Wickham Market and believe it should be sited further south on the A12 away from residential areas and near the A14.

The Ipswich Northern By-Pass

There is another large project scheduled for Ipswich in the next few years; the Ipswich Northern By-Pass.

This map clipped from the Ipswich Borough Council web site shows possible routes.

Note.

  1. Wickham Market is in the North-East corner of the map.
  2. One of the aims of the Northern by-pass is to open up land for housing.
  3. The railway between Ipswich and Darsham stations goes via Westerfield, Wiidbridge, Melton andWickham Market.
  4. Perhaps by phasing the developments, an area could be used for a Park-and-Ride, which has a road connection to the A 12.
  5. When the need for Park-and-Ride for Sizewell has decreased, the site could be handed over to housing.

It would certainly help, if the route of the Northern by-pass was settled soon.

Sizewell C – Where Will The Workers Live?

I have now written about, where the two Park-and-Ride sites are to be built.

  • The Northern Park-and-Ride is proposed for Darsham.
  • The Southern Park-and-Ride is proposed for Wickham Market.

I can now write about where the workers could be billeted.

I suspect there could be a Bibby Stockholm solution, where accommodation barges are used.

This Google Map shows the centre of Ipswich.

Note.

  1. There is a lot of space on the River Orwell.
  2. Ipswich station is in the North-West corner of the map.
  3. There could be a shuttle bus between the barge and the station.
  4. Trains could take workers to Darsham for buses to Sizewell.

There could even be direct buses to Sizewell.

This Google Map shows the centre of Lowestoft.

Note.

  1. The Bibby Stockholm is 100 metres long with a beam of 30 metres.
  2. Lowestoft station is close to the port.

Workers could take the train direct to the Northern Park-and-Ride for Sizewell C.

Sizewell C – North Park And Ride

This document on the Planning Inspectorate web site, is a description of the Northern Park-and-Ride for the Sizewell C Project.

This Google Map shows the area of the Park-and-Ride site.

Note.

  1. The main road running SW-NE is the A 12 between Ipswich, Felixstowe and Woodbridge in the South and Lowestoft and Great Yarmouth in the North.
  2. The East Suffolk Line runs North-South at the West side of the map.
  3. Darsham station, which is indicated by the red logo on a white background is situated, where road and railway cross.
  4. The Fox Inn is in the village of Darsham and indicated by an orange arrow.
  5. The pink arrow to the North-West of the Fox Inn indicates White House Farm.
  6. The lane going North-West from the A 12 to the North of the farm is Willow Marsh Lane.

The document on the Planning Inspectorate says this about the site.

The site comprises approximately 27.9 hectares (ha) of predominantly
agricultural land but also includes sections of the A12 and Willow Marsh Lane
towards the north of the site. It is located west of the village of Darsham and
west of the A12, to the east of the East Suffolk line, and to the north of
Darsham railway station (see Chapter 1, Figure 1.1 of this volume). Further
detail on the site and the environmental baseline is provided in Chapters 1
and 4 to 12 of this volume of the Environmental Statement.

This second Google Map shows Darsham station.

Note.

  1. Darsham station has long platforms.
  2. Crossing the line is by means of the level crossing.
  3. The Budgens store, which is indicated by the blue arrow also sells fuel.
  4. The station has a bus service.
  5. The Southern end of the Park-and-Ride site lies between the railway and the road at the North of the map.

The document on the Planning Inspectorate says this about walking between the Park-and-Ride site and the station.

There would be a pedestrian route from Darsham railway station along the
footway on the A12 to the south-east of the site. Pedestrians accessing the
site would leave the A12 and enter through a security gate provided in the
security fencing. Further details of access measures (such as key fobs,
CCTV, intercom system) would be agreed at the detailed design stage.

I could probably manage that at 76.

These are further thoughts.

The Current Rail Service

Currently, the rail service is as follows.

  1. One train per hour (tph) in both directions.
  2. |Trains are Class 755 trains, built by Stadler in Switzerland a few years ago.
  3. Each train can carry  up to 229 passengers.
  4. Up to three trains can run together.
  5. Trains going to and from Lowestoft in the North call at Oulton Broad South, Beccles, Brampton and Halesworth.
  6. Trains going to and from Ipswich in the South call at Saxmundham, Wickham Market, Melton and Woodbridge.
  7. Travellers for London Liverpool Street change at Ipswich.
  8. The first train from London Liverpool Street would get you to Darsham at 11:00.
  9. This is not a bad train service but it could be improved.

Direct Trains Between London Liverpool Street And Lowestoft

In 2016, I wrote Making Sense Of The New East Anglia Franchise.

I wrote the following about Greater Anglia’s plans to run four trains per day between London Liverpool Street and Lowestoft.

There are going to be four direct services between London and Lowestoft each day. This probably initially means two trains to London in the morning peak and two trains back in the evening one.

When, I first moved back to Suffolk in the 1970s, I regularly caught a diesel-hauled train from Wickham Market to London for the day.

This is all motherhood and apple pie for those in Lowestoft wanting to go to London, but I suspect it isn’t the easiest service for a train operator to schedule efficiently and make money.

Would a train operator really want to start a full train at Lowestoft at say six in the morning and then have it wait around all day in London before returning in the evening?

The East Suffolk Line from Ipswich to Lowestoft has the following characteristics.

  • It is fifty miles long.
  • It is not electrified.
  • It has a speed limit of 40-55 mph.
  • There are nine intermediate stations. Many are just a single platform, and car parking is fairly limited.
  • It has enough double-track and a passing loop at Beccles station to run a train in both directions at the same time.
  • As it ran long trains in the past, I suspect, that most of the stations have platforms that can handle at least six-carriage trains.
  • Trains would appear to take around ninety minutes for the whole journey

But the most important characteristic, is that every time the line is improved, more passengers come rushing out of the woodwork.

There would certainly be no problem with running bi-mode Flirts on this route, as London-Lowestoft is just the type of route for which they are designed.

  • They would use their on-board diesel engines on the East Suffolk Line.
  • As some would work along the busy lines to London, I suspect their top speed under electric power would be the same as the EMUs.
  • Services to and from London, once on the Great Eastern Main Line, would join the high-speed race to and from the capital.
  • At the start and finish of the day, the trains could use the electrified main line to position between Ipswich and Crown Point depot at around 100 mph.
  • Abellio could use either a single three- or four-car train or perhaps two trains coupled together.

This service would pass through Darsham station, so it could provide a direct link between London and the Park-and-Ride.

It might also stop at stations like Manningtree, Colchester, Chelmsford and Stratford.

I am fairly certain, that a London Liverpool Street and Lowestoft services, that stopped at Darsham station, would improve labour availability and construction efficiency at Sizewell C.

A Connection To Yarmouth

There used to be a direct Yarmouth to Lowestoft Line, but now it is possible to use the Wherry Lines, with a reverse at Reedham station.

So will we be seeing the direct London-Lowestoft trains being extended to Yarmouth?

As Yarmouth hasn’t had a direct connection to London for years and there are lots of fast, capable new trains, I wouldn’t be surprised.

Especially, as Network Rail are talking about reinstating the Reedham Chord to create a more direct route between East Anglia’s largest North-Eastern towns. This is said about the Reedham Chord in Direct Yarmouth Services in the Wikipedia entry for Lowestoft station.

In January 2015, a Network Rail study proposed the reintroduction of direct services between Lowestoft and Yarmouth by reinstating a spur at Reedham. Services could once again travel between two East Coast towns, with an estimated journey time of 33 minutes, via a reconstructed 34-chain (680 m) north-to-south arm of the former triangular junction at Reedham, which had been removed in c. 1880. The plans also involve relocating Reedham station nearer the junction, an idea which attracted criticism.

If we take these current approximate timings.

  • Ipswich to Lowestoft takes 90 minutes.
  • Lowestoft to Reedham takes 27 minutes.
  • Reedham to Yarmouth takes 16 minutes.

That means the service today would take 133 minutes, with a train reverse at Reedham station.

Note.

  1. Modern three-car bi-mode Flirt trains, with better speed, acceleration and braking than the current Class 170 trains.
  2. The short-cut along the Reedham Chord, which could save as much as ten minutes.
  3. A few selective improvements to save a minute here and there.
  4. Lowestoft station is redeveloped forty metres to the West and eighty metres to the South, as detailed in Wikipedia under Relocation Of The Station.
  5. I think it would be possible for an Ipswich-Yarmouth service to do the trip in around two hours.

The service would have the following characteristics.

  • It would be timetabled for under the all-important two hours.
  • Trains would turnround efficiently in a few minutes at either end of the line.
  • It could be hourly with four trains or two-hourly with just two, used to run the service.
  • All stops would be at the same minutes past each hour at each station.
  • Trains would always leave Ipswich and Yarmouth at the same number of minutes past the hour.
  • Lowestoft and Yarmouth get a regular hourly direct train service in just thirty-three minutes.
  • Intriguingly if the trains left Ipswich and Yarmouth at the same time, they would pass each other at Beccles station, which incorporates a passing loop.
  • As Beccles and its passing loop, fits so well into this schedule, I suspect that it was designed with the Reedham Chord and this type of service in mind.
  • There would be no prizes for guessing the beer, that should be served on a train on this route.

I don’t think any better than an hourly service, could be run, without some extra passing loops or double-track.

This extension would make commuting between Sizewell and Yarmouth easier.

Bus Route Between Darsham And Sizewell

The document on the Planning Inspectorate says this about the buses and the route.

There would be a maximum of 100 daily bus arrivals and 100 daily bus
departures from the proposed development to the Sizewell C main
development site.

Bus services between the proposed development and the Sizewell C main
development site would travel south on the A12 and use the new A12/B1122
roundabout (Yoxford Roundabout – see Volume 7 of the ES) to access the
B1122 and the Sizewell link road (once operational – see Volume 6 of the
ES) towards the Sizewell C main development site.

This Google Map shows Darsham station and the Sizewell site, as it exists today.

Note.

  1. The Sizewell site is in the South-East corner of the map.
  2. Darsham station is in the North-West corner of the map.

This second Google Map shows the A 12 between Darsham station and Yoxford.

Note.

  1. Darsham station is at the top of the map on the A 12.
  2. The village of Yoxford is on an S-bend of the A 12.
  3. A B& B is marked by a pink arrow.

The B 1122 connects Yoxford to the South-East corner of the map.

This third Google Map shows the route between Yoxford and Sizewell.

Note.

  1. Yoxford is in the North-West corner of the map.
  2. Sizewell is in the South-East corner of the map.
  3. Leiston Abbey is indicated by the arrow to the North of Leiston.

The B 1122 can be picked out through Middleton Moor and Theberton and then as it skirts Leiston Abbey.

Sizewell C seem to have made a good effort to get the workers to the site.

Why Isn’t A Passenger Train Run Between Ipswich And The Sizewell Site?

In Network Rail Prepares To Send Four Trains A Night Through Suffolk To Sizewell, I came to this conclusion.

I am fairly certain, that it is possible to move four freight trains in and out of the Sizewell site during the night, without doing any major works to the East Suffolk Line between Ipswich and Saxmundham junction.

  • Adding extra track at Wickham Market would probably cause major disruption.
  • Some level crossings will probably be improved.

But without a full double track between Ipswich and Saxmundham junction, I doubt there could be any increase in passenger services.

But with those track works, it might be possible to run an hourly service between Ipswich and Aldeburgh with calls at Westerfield, Woodbridge, Wickham Market, Saxmundham, Sizewell and Leiston.

This would give a two tph service between Saxmundham and Ipswich.

Objections To The Park-and-Ride

This document from Darsham Parish Council is entitled Consultation Response To Sizewell C.

This is the first paragraph.

Darsham Parish Council (Darsham PC) continues to oppose the proposed location of the Northern Park and Ride (NPR). We believe its location on an already busy single carriageway section of the A12 just north of the level crossing at Darsham Station, coupled with proposed roundabouts at Willow Marsh Lane and the A1120 junction in Yoxford are a recipe for traffic chaos extending northwards up the A12. We have no confidence in the traffic estimates submitted by EDF, which we believe underestimate the amount of local, through, agricultural and tourist traffic. This will be exacerbated by the proposed motel and further proposed development south of the station. We believe that traffic congestion on this main artery into Suffolk will adversely impact tourism throughout the AONB, which generates more than £360 million pa to the local economy (2018 figure). Further, we believe these volumes of traffic will generate excessive noise, vibration and pollution with serious negative impacts on those living alongside or close to the A12. Most significantly, Darsham PC has been advised that location of the NPR on this site could pose a significant flood risk to the railway (see below).

The Parish Council is also worried about flood risk to the railway.

The site of the NPR slopes down from Willow Marsh Lane towards the railway. A consulting engineer has advised us that the heavy clay soil here could pose a drainage and flood risk problem when compacted during the construction period. An appropriate sustainable semi-permeable surface could be utilised for car parking spaces to reduce run-off, with suitable drainage and reservoir capacity at the southern end to protect the railway from flooding. We submitted this evidence to EDF during the consultation period, but it has been ignored.

I suspect as with the opposition to Sizewell B, the opposition is led by second home owners, worried about the value of their investment.

TCP Is Using Hydrogen To Create Cleaner Construction Sites

The title of this post, is the same as that of this article on the Eastern Daily Press.

This is the sub-heading.

Air and noise pollution are challenges for every construction project. For green energy infrastructure developers especially, cutting emissions is a pressing conundrum.

These are the first four paragraphs.

Large-scale construction demands diesel-guzzling heavy plant and noisy diesel generators powering off-grid site work for years before a project generates its first clean energy.

Back in 2012, Andrew Barker identified hydrogen as a fuel of the future and a solution to pollution issues during construction projects in his Essex-based family business, Taylor Construction Plant (TCP Group).

His concerns about health issues caused by carbon emissions, combined with a drive to make a difference, led to game changing inventions using hydrogen to transform power for site operations – making sites better neighbours, with fewer health dangers to site workers and helping the drive against climate change.

He developed his first hydrogen powered product more than a decade ago – mobile lighting towers that are the flagship product for the business and first choice for building and maintenance projects across the UK on the mission to net zero.

It appears now Andrew Barker has a strong business, which can be found at this web site.

First Massive ‘Lego Block’ Beams Lifted For HS2’s Pioneering Thame Valley Viaduct

The title of this post, is the same as that of this press release from High Speed Two.

HS2 has begun lifting the first of 72 huge beams that will support the deck of the Thame Valley Viaduct – the first of its kind in the UK to have all major elements manufactured off site.

HS2 Bicester viaduct beam placement.

These paragraphs describe the building of the viaduct.

Engineers at the site near Aylesbury used two massive cranes to lift the beams – 25 metres long and weighing 90 tonnes each – into position on top of the viaduct piers, like giant Lego blocks.

Instead of using a more traditional approach, with multiple smaller beams for each span, the design team opted for a simple structural solution with just two larger hollow u-shaped beams per span, which allows for a lighter structure and simpler construction.

The lighter-weight design, inspired by viaducts on the Spanish high speed rail network, also reduces the amount of carbon-intensive concrete and steel in the structure – cutting its carbon footprint by around a third.

It doesn’t say, if they are using low-carbon concrete for the beams, but High Speed Two have used this material before.

Seratech’s Technology Explained

I first wrote about Seratech in Carbon-Neutral Concrete Prototype Wins €100k Architecture Prize For UK Scientists, after reading about this carbon-neutral concrete in the Architect’s Journal.

I have just received Seratech’s October 2023 Newsletter, which contains two must-read articles.

Olivine In The Age Of Climate Crisis

I’d never heard of olivine until I read about the architecture prize, that was won by Seratech.

This is the Wikipedia entry for olivine.

These are the first three paragraphs of Seratech’s article.

On the west coast of Norway, a few kilometres from the village of Åheim, is an open excavation pit – home to the largest commercial olivine deposit in the world.

This seaside quarry, run by Belgian industrial minerals company, Sibelco, works to extract olivine from the earth’s crust by drilling, blasting and crushing. A single blast (used to break up the rocks) removes up to 40,000 tonnes of olivine.

The site is predominantly powered by hydroelectricity and boasts a 4km conveyor system for transport which limits the need for heavy vehicle or double-handling of materials in a bid to reduce emissions.

This is Sibelco’s video of their impressive mining process.

Note.

The mining operation is fully-integrated with its own ort.

  1. The video does the mining operation justice.
  2. Sibelco aim to make the mining of olivine carbon-neutral.

Olivine has this Wikipedia entry, which gives more information.

This Google Map shows the port complex at Åheim.

It looks like mine, processing and port all on one site.

The Big Interview With Mike Eberlin

This is the sub-heading.

Former Managing Director of Tarmac Cement & Lime and chair of MPA Cement, Mike Eberlin, became Seratech’s business advisor in June this year. He was intrigued by the novel technology Sam Draper and Barney Shanks had uncovered

These paragraphs are a summary of what Mike Eberlin said.

As we begin to talk, Mike is quick to point out there are two big advantages to Seratech: “They are using magnesium silicate as a starting material which produces silica as a cement replacement and magnesium oxide which can then absorb CO2”.

The CO2 absorption is what fascinates Mike as the type of magnesium carbonate Seratech produces is a “slightly unstable” version which when cured, becomes stable and reverts to the rock-like substance you would find in nature. “This came as a surprise because the chemistry wouldn’t indicate that was possible,” he explains.

Following this discovery, and as Seratech’s research progressed, it soon became apparent that the magnesium carbonate lends itself well as a binder and can be used in applications like building blocks and plasterboard: “It’s effectively carbon capture and use, not carbon capture and storage because you are mineralising the CO2 into a product.

“We end up in this clever situation whereby it’s not that we don’t emit the CO2, it’s better than that, we absorb CO2 and create two binders that replace cement”.

That’s what I call an endorsement.

Conclusion

I have this feeling that Seratech will be a very significant company in a couple of years.

Low-Carbon Concrete: Separating Greenwash From Reality

The title of this post is the same as that of this article from Construction Management.

This is the sub-heading.

Tales of low-carbon concrete abound, but what exactly does that mean? Kristina Smith looks at what’s in the mix.

This is a paragraph, which shows the scale of the problem.

The oft-quoted statistic is that cement contributes to 7% of the world’s carbon emissions. However, MPA says that in the UK concrete and cement account for just 1.5% of emissions. “From 1990 we have reduced our absolute emissions by 53%, which is faster than the overall economy, mainly by improving energy efficiency at the plants,” says Khosravi.

Noushin Khosravi, is sustainable construction manager at the Concrete Centre, which is part of Mineral Products Association (MPA).

 

Companies mentioned include.

I find the Seratech process amazing as it takes carbon dioxide straight from flues to make the cement.

Could we fit a Seratech cement process on the back of a gas-fired power station?

The article is a must-read summary of where the technology is with respect to low-carbon concrete.
