Could Centrica Build An Alternative Grid For The UK?
Andy Burnham’s Speech In Liverpool Introduced The Great British Grid
This extract is what he said on energy and the grid.
One of the biggest barriers to growth in the UK is the cost of energy. British businesses and billpayers pay some of the highest energy costs in Europe.
Within 10 years, I want those costs to be in line with our neighbours.
This means reforming a broken energy market so it better serves the public interest.
We are already taking more control of our electricity prices with a massive expansion of home-grown renewables and nuclear. I have asked Miatta to speed up the breaking of the link between what we pay for power at home and the international gas market, to get bills down.
And we will be pragmatic in relation to the North Sea as we build a bridge to a clean energy future and face the climate crisis.
But it’s not just the price. The system needs to work better too. You would not believe how many businesses complain to me they can’t get going because they can’t get connected to the grid.
It pushes costs up. It drags growth down. And it holds Britain back. We won’t get the growth and inward investment we need if we don’t fix it.
So, for the first time, we will have a national energy plan and we will bring back local democratic control through a stronger role for mayors and local leaders.
But we must go further. Today I can announce our plan for Great British Grid. A new branch of Great British Energy. A publicly-owned company that will challenge the private sector operators.
But is Andy Burnham’s plan realisable?
The Great Grid Upgrade From Norwich To Tilbury
National Grid are aiming to replace the grid between Norwich and Tilbury to add extra capacity and the details of the project are on this web site.
This is a map of the route.
To ascertain the level of objections, I asked Google AI “Norwich to Tilbury grid objections” and received this reply.
Local councils, residents, and organizations object to National Grid’s Norwich to Tilbury Project primarily due to the visual and ecological damage of using 50-meter overhead pylons instead of offshore or underground alternatives.
Key Objections and Concerns
Overhead Pylons vs. Alternatives: Opposition to roughly 100 miles (159–183 km) of towering onshore overground lines. Objectors demand fully costed offshore high-voltage direct current (HVDC) or underground cabling options.
Environmental & Landscape Harm: Severe impact on protected and valued landscapes, including the Dedham Vale national landscape and Waveney Valley, alongside extensive tree loss and disruption to local wildlife habitats.
Heritage & Property Impacts: Damage to the settings of historic buildings and significant property or land devaluation, including negative impacts on planned developments like the Dunton Hills Garden Village in Brentwood.
Unrealistic Delivery Timeline: Concern that the targeted 2030/2031 completion deadline is overly ambitious, forcing rushed implementation without proper scrutiny of cumulative effects from multiple East Anglian energy projects.
Community Disruption: Strain on local highways, disruptive weekend and bank holiday working hours, agricultural disruption, and a lack of adequate community compensation or tangible social value.
The Nimbys don’t seem very keen on more and bigger overhead power lines.
Conclusion
I believe building a second set of power lines across the country will be very difficult, if not impossible.
The Investment Of Centrica And Others In innovative Energy Technology
I think we’ll see innovation from the likes of Centrica, Octopus, National Grid and others, as to how we get our energy delivered.
Centrica and others, who include the UK Government, have backed four British companies, that I’m sure will be used in the grid of 2030.
- Ceres have developed a fuel cell that runs on hydrogen, biomethane or natural gas. It was thought it would be used to power data centres, but it could be used to provide power anywhere there is a gas supply, like a big factory or a new housing estate.
- Heata was developed by British Gas Research and is part of a data centre, which sits in a domestic hot water tank and the waste heat gives you affordable hot water.
- Highview Power make liquid-air batteries up to 300 MW/3.2 GWh. Significantly, Andy Burnham performed the groundbreaking for a 50 MW/300 MWh battery in Manchester, when he was Mayor of Greater Manchester.
- HiiROC from Hull University have a way to make hydrogen that uses only a fifth of the electricity. Cemex are using HiiROC to make low-carbon cement at Rugby. I also think Jim Ratcliffe has plans for HiiROC, as he is an investor with Centrica and others.
Could Centrica build an innovative Great British Grid from their investments?
I don’t think so because of the problem I indicated earlier with Norwich to Tilbury of putting up more overhead cables.
But all of these four companies can provide support and enhancement to the existing grid.
- Ceres could be used to provide extra power, where it is needed, if there is a suitable gas supply.
- Heata could be used to give a large proportion of houses and flats affordable hot water.
- Highview Power could be used to provide energy storage where too much energy is being generated at times and needs to be stored for a number of hours.
- I believe that many large wind farms will be connected to the grid, with a Highview Power battery at the sub-station.
- I also believe that we could see Highview Power batteries installed offshore to smooth wind farm output.
- HiiROC could produce hydrogen when and where it is needed.
The big problem will be that the grid will get more complicated and will be more difficult to control.
In Centrica And Return Partner To Scale Battery Flexibility In Germany, I ask Google AI if Centrica are good at optimising batteries and received this reply.
Yes, Centrica is considered a strong and established player in grid battery (BESS) optimisation.
Centrica Energy leverages over 15 years of flexible asset trading experience and has actively optimised battery energy storage systems since 2018. They currently manage over 950 MW of grid-scale batteries on contract across the UK and Europe.
It may be difficult to manage all these assets, but it does appear that Centrica have the mathematicians and engineers, who are up to the task.
The Future Of Nuclear
Consider.
- The four nuclear stations at Hartlepool, Heysham 1, Heysham 2 and Torness are to be shut down by March 2030, which will lose approximately 5 GW of zero-carbon electricity.
- Hinckley Point C will deliver 3.2 GW from the early 2030s.
- Sizewell C will deliver 3.2 GW at some time in the future.
Can we rely on solar and wind power to power the UK?
It is not a question of can, but we have to.
But Centrica have made a bold move to link up with X-energy of the US to build a fleet of small modular reactors called an Xe-100.
- I wrote about the initial deal in Centrica And X-energy Agree To Deploy UK’s First Advanced Modular Reactors.
- In Hartlepool Nuclear Reactor Moves To UK Regulatory Assessment, I talk about how the first reactor will be built at Hartlepool.
- In Centrica, X-energy Advance Nuclear Plans As UK Regulators To Begin Design Review For Xe-100, I say more about the design and the parners in the Xe-100.
- In With Federal Funding Windfall, X-energy Advances Small Nuclear Reactor, I talk about US Federal funding for X-energy.
- In TRISO-X Completes Vertical Construction Of TX-1 Fuel Fabrication Facility, I describe how they are cracking on with the fuel facility in the US.
It certainly, seems to be a project that has started with a certain degree of momentum, which says to me, they have got the project management right.
But believe that these 80 MW Xe-100 reactors, if strategically placed around the country will keep us going as older nuclear and gas power stations are retired.
The Relationship Between Andy Burnham And Chris O’Shea
I wrote about this in Have Chris O’Shea And Andy Burnham Met?
I will assume its a good relationship, until proven otherwise.
Conclusion
I wonder whether in the end, the Great British Grid is a series of extensions to the current grid we have.
Cemex To Install World-First Hydrogen Process At UK Cement Plant
The title of this post, is the same as that of this article on The Chemical Engineer from 2024.
These two paragraphs introduce the article.
CEMEX is set to trial a process developed by Hiiroc that uses plasma to produce hydrogen for greener industrial heat at its cement plant in Rugby, UK.
Cemex is finalising contract details now with UK-based process developer Hiiroc and expects to start engineering studies early next year with hydrogen production set for a “hard deadline” of January 2026. The cement major thinks the process is a better bet for producing hydrogen than water electrolysis because it requires 80% less electricity and wins out over steam methane reforming because it doesn’t produce CO2.
I believe that this process, which has its origins in Hull University, could revolutionise the manufacture of zero-carbon hydrogen.
The article describes its first big application at Cemex’s Rugby cement plant.
There are obviously issues to be solved and the article is mainly an interview with Alfredo Carrato, who is innovation advisor at Cemex Ventures.
These are some thoughts.
HiiROC Is Containerised
The article says this.
Carrato expects the changes required to integrate the process at the Rugby plant to be minimal. One or two of Hiiroc’s containerised process units will be plugged into the grid and pipes installed to carry hydrogen to the existing kiln where a new burner will be installed to combust the hydrogen producing heat to convert limestone to clinker.
It also says this.
If successful, the Rugby plant could see eight or nine of Hiiroc’s modules installed at the site, Carrato said.
There could be a lot of low-carbon cement coming out of Rugby.
But containerisation also means that any factory using natural gas for a lot of heat, can plug in a number of Hiiroc’s containerised process units and decarbonise.
Worldwide Expansion
The article says this.
“We do have plans to expand this across our operations worldwide for a number of reasons. Hydrogen certainly is a relevant vector that we are considering to decarbonise our operations. And second, the modularity of the solution allows for a quick deployment.”
Cemex Aim To Be Net Zero By 2050
The article says this.
Cemex has set itself a target of becoming net zero by 2050. The Hiiroc process can make use of biomethane so could allow Cemex to replace its use of fossil fuel natural gas. It could also use renewable electricity to power its plasma burners. In terms of output, the process produces carbon black which can be used as an additive in its cement-making operations or sold for use in tyres, rubbers, plastics, inks, and toners.
“Because of the stoichiometry, the volume of carbon black is pretty significant, meaning we are not able to take the entirety of what is produced. So, we need to figure out how to also monetise it.”
Hiiroc is searching for alternative markets too. It has partnered with researchers in Europe and the US to investigate how the carbon black from its process could be used in other applications including filters, soil enhancers, and animal feed.
Note.
- The process can run on biomethane, as well as natural gas and chemical plant flare gas.
- The carbon black could be a long-term problem, but I suspect a use will be found.
Having worked in integrated chemical plants, I believe innovative uses for both feedstocks and what to do with the carbon black will be found.
Water Stress
The article says this.
Carrato said: “We’re looking at not only the carbon footprint, but also the stress on water. Water electrolysis has a lot of water demand, whereas technology such as Hiiroc has none. In regions where there’s a lot of water scarcity, we believe that Hiiroc can move the needle [for industrial decarbonisation] way better than water electrolysis.”
Any water problems seem soluble.
Conclusion
Alfredo Carrato of Cemex Ventures seems to be enthusiastic about his charge.
Cummins To Cease New Electrolyser Activity Amid Worsening Market
The title of this post, is the same as that of this article on Renewables Now.
These are the first three paragraphs.
Cummins Inc has decided to stop new commercial activity in the electrolysers space following a strategic review of the segment launched last year, citing deteriorating market conditions and weakening customer demand.
The decision is linked to USD 458 million (EUR 388.4m) of charges for the full-year 2025 related to the electrolyser business within the company’s zero-emission technologies arm, Accelera, of which USD 415 million were non-cash charges.
The company noted that it will continue to fulfil existing customer commitments before winding down new commercial activity in the segment.
Although, I am in favour of using hydrogen as a fuel, I recognise, that traditional electrolysis is not the most efficient process.
These methods are more efficient.
HiiROC
- HiiROC use a process, that they call Thermal Plasma Electrolysis to split any hydrocarbon gas into hydrogen and carbon black.
- HiiROC originated in the University of Hull.
- Typical gases that can be used are chemical plant off-gas, biomethane and methane.
- I like the ability to use chemical plant off-gas, as some of this is particularly nasty and HiiROC may offer safe disposal.
But the big advantage is that the HiiROC process is five times more energy efficient than traditional electrolysis.
The carbon black is no useless by-product, but has several valuable uses in its own right, which are detailed in its Wikipedia entry.
These two paragraphs from Wikipedia, give a summary of the more common uses of carbon black.
The most common use (70%) of carbon black is as a 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.
Carbon black is added to polypropylene because it absorbs ultraviolet radiation, which otherwise causes the material to degrade. Carbon black particles are also employed in some radar absorbent materials, in photocopier and laser printer toner, and in other inks and paints. The high tinting strength and stability of carbon black has also provided use in coloring of resins and films. Carbon black has been used in various applications for electronics. A good conductor of electricity, carbon black is used as a filler mixed in plastics, elastomer, films, adhesives, and paints. It is used as an antistatic additive agent in automobile fuel caps and pipes.
It can also be used as a soil improver in agriculture.
HiiROC would appear to be five times more energy efficient than traditional electrolysis.
I would also rate the range of their investors as a particular strength.
Google AI lists these companies as investors.
HiiROC, a UK-based developer of plasma torch technology for “turquoise” hydrogen production, is backed by a consortium of industrial and strategic investors. Key investors include Centrica, Melrose Industries, Hyundai Motor Company, Kia, HydrogenOne Capital, CEMEX Ventures, Wintershall Dea, and VNG.
Note.
- CEMEX must be going to decarbonise cement making.
- Melrose describe themselves as an industry-leading aerospace technology provider.
- Will we be seeing hydrogen cars from Korean manufacturers?
- Wintershall Dea is Europe’s leading independent gas and oil company.
HiiROC has an impressive list of investors.
Bloom Energy
I wrote about Bloom Energy’s process in Westinghouse And Bloom Energy To Team Up For Pink Hydrogen.
This method also looks promising.
- Westinghouse Electric Company is an American builder of nuclear power stations.
- Bloom Energy Corporation make a solid-oxide electrolyser.
- Pink hydrogen is green hydrogen produced using nuclear power.
It uses electrolysis at a higher temperature, which speeds it up.
Desert Bloom
This is an Australian process, that I wrote about in 10GW Green Hydrogen Project Aims To Electrolyze Water Drawn From Desert Air.
Conclusion
You can understand, why Cummins are getting jumpy!
But you have to remember that when I worked in a hydrogen plant in the 1960s, the hydrogen was an unwanted by-product and it was mixed with coal gas and sent down the power station to raise steam, so that it could be used to do something useful.
Hydrogen Deployment Milestone For Cemex And HiiROC
The title of this post, is the same as that of this article on Agg-Net.
This is the sub-heading.
Cemex kick-start first-of-a-kind low-carbon hydrogen project using thermal plasma electrolysis in cement production
These first two paragraphs add more detail.
CEMEX Ventures, Cemex’s corporate venture capital (CVC) and open innovation unit, announced today an initial hydrogen deployment at industrial scale with HiiROC, the pioneering British hydrogen company that produces affordable, clean hydrogen, at their Rugby cement plant in the UK.
Hydrogen has emerged as a low-carbon energy source within the construction industry’s decarbonization roadmap and offers potential as an energy solution to help reduce the sector’s reliance on fossil fuels and lower CO2 emissions. This venture marks a significant milestone for Cemex, as it represents the beginning of a large-scale strategic project plan with the aim to further lower their carbon emissions in cement production.
These third paragraph is a good outline of HiiROC and how it can be deployed.
HiiROC produce carbon-neutral hydrogen using their proprietary Thermal Plasma Electrolysis (TPE) process, which requires just one-fifth of the electrical energy used in water electrolysis and captures carbon as a solid by-product, avoiding CO2 emissions – a game-changer for the industry. HiiROC’s modular solution can be deployed as single units to full-scale industrial plants, and the hydrogen produced can be used as an alternative energy source to fuel clinker production processes, helping Cemex to achieve their decarbonization goals.
Centrica, Cemex, Hyundai, Kia and others are investors in HiiROC.
I asked Google AI, what percentage of carbon emissions came from cement production and got this answer.
Cement production accounts for roughly 8% of global carbon dioxide (CO2) emissions, according to think tank Chatham House. This makes it a significant contributor to climate change, with the industry’s emissions comparable to the total emissions of some countries.
If HiiROC can take a big bite out of carbon emissions, by reducing cement production’s 8 % share, they would be on a winner.
What Is The Collective Noun For Cement Mixer Trucks?
I took these pictures on Eldon Street and Moorgate this morning.
Note.
- There was obviously a big pour going on in the rebuilding of Broadgate.
- I suspect those outside the hotel in the street restaurant, we’re too amused by the cabaret.
- Cemex were providing the concrete.
Perhaps in view of the location, the collective noun is a pollution of cement mixer trucks.
In Cummins Agrees To Integrate Its Hydrogen ICE Technology Into Terex® Advance Trucks, I describe the latest design of cement mixer trucks from the United States.
This is the European-sized member of the range.
Note.
- Front is to the right.
- The engine is in the pod at the other end.
- The engine can be one of Cummins’s hydrogen internal combustion engines.
These trucks would be much more city-friendly.
