UK: Hanson UK says that its planned installation of a carbon capture system at its Padeswood cement plant in Flintshire has proceeded to the due diligence and negotiations stage. The project aims to achieve net zero CO₂ cement production by capturing 800,000t/yr of CO₂. It is part of the HyNet North West array of projects, which combines green hydrogen and carbon capture to build a first-of-its-kind industrial decarbonisation cluster.

Hanson UK CEO Simon Willis said “I would like to thank the government and all of those that supported us in our bid to receive funding which will enable us to help decarbonise the construction industry and meet our overall ambition to become a net zero business. This global exemplar project will provide net zero construction materials for major projects across the country, from new offshore wind farms and nuclear power stations to clean transport infrastructure.”

UK: Hanson says it has become one of the first companies in the UK to be certified to the new ISO 19443 standard, for companies supplying products and services that are important to nuclear safety. The subsidiary of Germany-based Heidelberg Materials is a supplier to the nuclear sector and is currently working with three of the delivery teams on the Hinkley Point C (HPC) project.

Stewart Cameron, head of nuclear at Hanson UK said “It has taken our HPC team a year to complete the ISO 19443 process.” He added, “Although it is not a requirement for our supplies to the project, it recognises the efforts we make – and helps others understand – why nuclear needs to be different.”

UK: Heidelberg Materials subsidiary Hanson has awarded a contract to Mitsubishi Heavy Industries subsidiary MHI Engineering for installation of a planned 800,000t/yr carbon capture system at its Padeswood cement plant in Flintshire. The producer plans to store its captured CO₂ in exhausted Irish Sea natural gas fields. MHI Engineering will carry out a pre-front-end engineering design study using its Advanced KM CDR solvent-based process. The supplier developed the process jointly with fellow Japan-based company Kansai Electric Power.

The project will be MHI Engineering's third of its kind at a cement plant, following similar commissions with Lehigh Cement in Canada and Tokuyama Cement in Canada.

UK: Germany-based Heidelberg Materials has signed a deal for the acquisition of Mick George Group, the leading concrete recycling company in the East Midlands and East of England. Mick George Group’s 40 sites span bulk excavation, earthmoving and demolition services and demolition waste removal and management, as well as ready-mix concrete and aggregates distribution.

Heidelberg Materials Western and Southern Europe director Jon Morrish said “With the acquisition of Mick George, we are clearly moving towards establishing a truly circular materials and services offer in our UK business. I warmly welcome all 1000 Mick George employees to Heidelberg Materials and look forward to further developing the business together.”

Heidelberg Materials aims to offer circular alternatives for half of its products by 2050.

UK: Hanson has announced a 'carbon capture breakthrough' in its use of recycled concrete paste (RCP) in the wet scrubber of its Ribblesdale cement plant in Lancashire. In under 30 minutes, 15t of RCP was able to capture 1.5t of CO₂ from the plant's flue emissions. Carbonated RCP is suitable to replace limestone in cement production.

Hanson's sustainability director Marian Garfield said “The trial was carried out with our parent company Heidelberg Materials’ research and development team, and marks another important milestone in our carbon capture journey."

Argos Honduras revealed this week that it has been testing the injection of hydrogen into the kiln of its integrated Piedras Azules cement plant. It has completed a pilot with Portugal-based company UTIS. As part of the process it has been trialling, it has split water by electrolysis and then injected the hydrogen and oxygen directly into the kiln via the main burner. The pilot has reportedly increased clinker production and reduced petcoke consumption at the plant.

Argos is far from alone in using hydrogen in this way. At the end of August 2022 Cemex said that it was also starting to use hydrogen at its San Pedro de Macorís cement plant in the Dominican Republic. CRH UK-subsidiary Tarmac completed a trial in July 2022 using hydrogen as an alternative to natural gas at its Tunstead lime plant. HeidelbergCement UK-subsidiary Hanson also ran a successful trial using hydrogen as part of the fuel mix at its Ribblesdale cement plant in 2021. The government-funded trial used a combination of hydrogen (39%), meat and bone meal (12%) and glycerine (49%) to reach a 100% alternative fuels substitution rate. In 2021 Hanson reported that fuel switching to hydrogen could help it reduce its 2050 CO₂ emissions by about 3%, or by -35kg CO₂/t of cement product.

Cemex appears to be a leader in using hydrogen in this way. The Mexico-based company started injecting hydrogen in 2019 and retrofitted all of its European cement plants with the technology to do so in 2020. It then said it wanted to roll this out to the rest of its operations. The project in the Dominican Republic is an example of this. In February 2022 it announced an investment in HiiROC, a UK-based company that has developed a method using thermal plasma electrolysis to convert biomethane, flare gas, or natural gas into hydrogen. The stated aim of this investment was to increase Cemex's hydrogen injection capacity in its cement kilns and to increase its alternative fuel substitution rate. Back in 2020 Cemex said that it planned to use hydrogen injection to contribute 5% of its progress towards its 2030 CO₂ emissions reduction target along with other measures such as increasing its thermal substitution rate and reducing its clinker factor.

As can be seen above there are a number of examples of hydrogen injection being used in cement plants in Europe and the Americas. However, there is very little actual data available publicly at this stage on how much hydrogen that the plants are actually using. For example, Cemex may have hydrogen injection equipment installed at all of its plants in Europe but it is unclear how many plants are actually using it. This is understandable though, given how commercially sensitive the fuel mix of a cement plant is and in Cemex’s case if it wishes to maintain a leader’s advantage in using a new technology.

It is interesting to see, in what has been released so far, the focus on doing deals with companies that supply electrolysis technology such as HiiROC and UTIS. A feasibility study ahead of the Hanson trial at Ribblesdale by the MPA, Cinar and the VDZ suggested that upgrading a kiln burner and adding all the necessary hydrogen storage and pipework could cost at least Euro400,000. However, this study also pointed out that the cost of hydrogen made a big difference to the cost of the CO₂ saving from using it as an alternative fuel. Hence the focus on the technology partners. It will be interesting to see how many more hydrogen injection projects are announced in the coming months and years and, crucially, who is providing the technology to supply the hydrogen.

For more information on the use of hydrogen in cement production see the proceedings from the 15th Global CemFuels Conference & Exhibition where presentations on the topic were given by Cemex and the VDZ

UK: HeidelbergCement subsidiary Hanson’s plan for the installation of a carbon capture system at its Padeswood cement plant has proceeded to the due diligence stage for funding from the UK government’s Department for Business, Energy and Industrial Strategy. The project is one of 20 from the East Coast Cluster and HyNet North West Consortium to make the shortlist for this phase of the approval process.

If successful, Hanson will be able to capture 800,000t/yr of CO₂ and produce carbon neutral cement at the Padeswood plant by 2027. It will create 54 new skilled full-time jobs.

UK: Hanson plans to install a C-Capture solvent-based carbon capture system at its Ketton cement plant in Rutland. The producer says that the technology reduces energy requirements per tonne of CO₂ by 40% compared to other capture systems.

Chief executive officer Simon Wills said “Carbon capture is a critical part of our strategy to decarbonise cement production, and essential if we are to reach net zero carbon by 2050. If successful, the C-Capture process has the potential to be rolled-out across other sites across the HeidelbergCement Group.”

UK: Hanson has signed a memorandum of understanding with Shell to work together to explore opportunities that help the construction industry’s transition to net zero emissions.

Under the agreement the companies plan to explore: using hydrogen for transport and industrial processes; using capture utilisation and storage (CCUS) in cement production; looking at lower carbon fuels and electric vehicles; digital innovations in energy production, consumption and efficiency; improving bitumen and asphalt technology; and renewable energy sources such as solar installations and batteries to replace diesel generators. In addition, the companies say they will consider the possibility of collaborating in future business opportunities or new business models, which will create value and scope for further decarbonisation.

Hanson’s chief executive officer Simon Willis said, “We are already working together on several initiatives to decarbonise asphalt with bitumen materials and innovations which promote long life, increased use of recycled materials, low carbon products and the circular economy.” He added that “Hanson and Shell have a long-established working relationship and are committed to sharing knowledge and resources to jointly work on projects that will facilitate our transition to net zero emissions.”

UK: Road building company Hanson Contracting has begun rolling out Causeway Ermeo mobile workforce management software across its operations. The technology will replace paper forms and workflows. The software connects construction sites and offices through digital workflows, with easy-to-use reporting functions. Hanson Contracting plans to also digitise its timesheets, risk assessments, plant inspections, holiday requests and other manual processes.

Business manager Chris Harrison said “There is a lot of excitement from our business improvement team for Causeway Ermeo. We are always looking for any efficiencies and lean improvements to make in the business, and we see this solution as a key one." He added “We want data and technology to be at the heart of everything that we do. It gives us better operational and commercial performance on-site and also aligns us with our key customer’s vision for the future, in line with the National Highways Digital Roads strategy.”
