Cummins Enters Collaboration To Demonstrate Hydrogen Ecosystem
The title of this post, is the same as that of this article from Rental Management.
This is the first three paragraphs.
Cummins®, Columbus, Ind., has signed a Memorandum of Understanding (MoU) with Terex® Advance Mixer, Fort Wayne, Ind., a subsidiary of Terex Corp.; Edge Materials, Cloverdale, Ind.; and PCC Hydrogen, Louisville, Ky., to produce, trial and prove concrete mixer trucks powered by Cummins’ zero-carbon, hydrogen-fueled internal combustion engines.
The project aims to develop a full hydrogen ecosystem together with a hydrogen producer, vehicle manufacturer and end user. It is the first MoU of its kind signed by Cummins.
he four companies will unite their efforts, which will see Cummins’ X15H hydrogen internal combustion engines integrated into the Terex Advance Commander Series of front-discharge concrete mixer trucks. Edge Materials, a ready-mix concrete provider and Terex Advance customers will operate the hydrogen-powered trucks in challenging real-world environments including on construction sites and critical infrastructure projects. PCC Hydrogen, an ultra-low carbon intensity hydrogen producer, will supply the hydrogen fuel as well as stationary storage and dispensing services.
Note.
- The X15H engine also comes in diesel and natural gas versions.
- Cummins also make electrolysers, that can produce hydrogen.
- It looks like the collaboration has all bases covered.
- I suspect similar deals could be done all over the world and with other types of trucks.
It all sounds like a sensible way to go to me.
Silvertown Tunnel: Cracks In Mayoral Policies
The title of this post is the same as that of this article on the BBC.
This is the sub-heading.
It is an infrastructure project that is well-underway with the boring almost completed — but it has a very low profile.
These are the first three paragraphs.
Every step of the Crossrail tunnelling, the media were invited along. Not so with this project.
This is Silvertown Tunnel. It is more than 1km long and will be London’s first road tunnel in over 30 years.
Perhaps one of the reasons it isn’t being pushed publicity-wise, is it is very controversial.
Tom Edwards gives a detailed outline of why the tunnel is controversial.
Under a heading of HGVs Using Bus Lanes, this is said.
Instead of using the Dartford Crossing, larger HGVs will be able to use the tunnel — and its bus lane.
Campaigners said that will mean more HGVs going through Newham and Greenwich.
I’ve also never heard this before.
Sheila Keeble, of the Greenwich Society, said the tunnel “will be magnet for bigger traffic than we’ve got at the moment”.
“One of the issues we have is all the developers are now looking at building distribution centres,” she said.
“At the moment the Blackwall Tunnel protects us from bigger traffic… Silvertown won’t.”
That is all very logical and I suspect we’ll see larger trucks in Hackney and Waltham Forest too!
There was also this bit of nonsense from Transport for London.
TfL says the tunnel will lead to an overall improvement in air quality.
How will all those trucks through the two tunnels reduce pollution?
In 2024, London must vote for a Mayor, who understands hydrogen, mathematics and science!
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.
- Capital Concrete with their Earth Friendly Concrete.
- CarbonCure Technologies, which I wrote about in Mote – World’s First Carbon Removal Plant Converting Wood Waste To Hydrogen.
- Seratech, which I wrote about in Carbon-Neutral Concrete Prototype Wins €100k Architecture Prize For UK Scientists.
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.
Should Hydrogen-Powered Trucks Pay A Lower Charge In The Silvertown And Blackwall Tunnels?
London has a lot of heavy diesel trucks, which include.
Cement mixer trucks.
Large eight-wheeler trucks transporting aggregate, building materials and construction spoil to and from construction sites.
Council refuse trucks.
Skip trucks.
Supermarket delivery trucks.
They are large polluters and the only way they will be made zero-carbon, will be to use hydrogen.
In Cummins Agrees To Integrate Its Hydrogen ICE Technology Into Terex® Advance Trucks, I write about how Cummins and Terex are going to be building hydrogen-powered cement mixers.
This picture shows the baby of the range, which could be ideal for a smaller country like the UK.
Note how it is the other way round to traditional cement mixer trucks.
As companies are now selling low-carbon concrete in the UK, I suspect, it won’t be long before they will be delivering it in a hydrogen-powered zero-carbon truck.
If hydrogen-powered trucks could be given an economic boost, by lowering their charges for the Silvertown And Blackwall Tunnels, this might increase their uptake by owners of large trucks, which would in turn reduce pollution.
But this would need the election of a London Mayor, who had a hydrogen policy other than ignore it and hope it goes away.
