Germany: Holcim Deutschland has broken ground on the construction of a new kiln line and CO₂ processing unit at its Lägerdorf cement plant in Schleswig-Holstein. The line will feature an OxyFuel kiln, supplied by ThyssenKrupp. ThyssenKrupp’s OxyFuel technology will assist in the capture of 1.2Mt/yr (nearly 100%) of CO₂ from the plant. The partners described the upcoming upgraded Lägerdorf plant as one of the world's first carbon-neutral cement plants.

Holcim Deutschland CEO Thorsten Hahn said "We're laying the groundwork for a sustainable world through cement. Cement is essential for our cities, factories, homes, bridges and beyond. As we transition towards renewable energy, we must also construct the foundations and structures for wind turbines and railway tracks. With our climate-neutral cement plant, we ensure that this vital building material remains accessible without further harm to the atmosphere."

ThyssenKrupp Decarbon Technologies’ chief strategy officer Cetin Nazikkol said “It’s vital to switch to climate-friendly processes. By enriching CO₂ by means of the pure OxyFuel technology we’ve developed, we help our customers capture almost all of the CO₂ arising in the production process and so reuse it in a sustainable manner. Given that global cement production is more than 4Bnt/yr, we see enormous growth potential for our innovative technology.”

Switzerland: The Global Cement and Concrete Association (GCCA) is holding its Innovandi Global Cement and Concrete Research Network (GCCRN) Spring Week at the École polytechnique fédérale de Lausanne (EPFL) campus on 22 – 26 April 2024. 450 delegates from over 40 academic institutions will attend the event, featuring workshops, idea exchanges and progress reviews focused on the decarbonisation of cement and concrete by 2050. Topics include the use of AI, alternative materials and processes, concrete recycling, renewables, kiln electrification and carbon capture.

GCCRN industrial chair and Cemex global research development vice president and Davide Zampini said “If we are to reach our goal of net zero concrete by 2050, then we cannot do so alone. We need to explore as well as harness solutions and collaboration well beyond our industry. That’s why Spring Week is so important.”

GCCRN scientific chair Karen Scrivener said “Everyone here at EPFL is proud to be hosting this year’s Spring Week, anticipated as our largest gathering yet, marking a significant milestone in our journey toward net zero research.”

Poland: Polish cement producers are set to build carbon capture installations, supported by government policies. After a decline in production from nearly 19Mt in 2022 to about 16.5Mt in 2023, the industry is facing an increase in cheaper imports from outside the EU, particularly Ukraine, and CO₂ emission fees that account for 30% of the cost of 1t of cement, according to the Dziennik Gazeta Prawna newspaper. The EU has also introduced a carbon border adjustment mechanism (CBAM) for imports.

Despite these challenges, the Kujawy cement plant in Bielawy, owned by Holcim, is launching the large-scale implementation of carbon capture and storage (CCS) technology.

Holcim Polska's president, Maciej Sypek, said "The construction of carbon capture installations in our plants will cost between €320m and €400m. We received a €264m grant from the European Commission's Innovation Fund." According to Sypek, the project is currently in the design phase, with construction expected to start in 2025 and operations beginning in early 2028.

The implementation of CCS at the Kujawy plant could potentially lead to an industry-wide adoption of the technology, costing between US$3.7bn and US$4.9bn, according to the newspaper. Holcim Polska plans to liquefy the CO₂ and transport it by rail to a terminal in Gdańsk, where it will be shipped to the North Sea for underground storage. Cement producers are urging the Polish government to appoint a commissioner for CCS infrastructure and to enact legislative changes to support the construction of such installations. They also believe that rapid modernisation of the energy sector needs to occur to support the energy-intensive process of gas capture.

Global: The Global Cement and Concrete Association (GCCA) has received nearly 100 applications from worldwide tech start-ups for its Innovandi Open Challenge, which targets the decarbonisation of cement and concrete. This year's challenge is centred on carbon capture, utilisation and storage (CCUS) technologies.

Thomas Guillot, GCCA’s Chief Executive, said "There are already more than 100 CCUS cement industry pilots, projects and announcements in the pipeline across the world – with the world’s first commercial scale carbon capture and storage plant set to complete later this year. Innovation will help our industry to deploy this technology further and faster."

Claude Loréa, GCCA’s Cement, Innovation and ESG Director, said "It’s really encouraging to see nearly 100 applications for our Innovandi Open Challenge and from all parts of the world. As well as the US, UK and India, we’ve received applications from China, Greece and Australia for the first time. It demonstrates the high level of interest in working with our industry to make cement and concrete net zero. We’re looking forward to assessing all the applications, in detail."

The association, alongside over 50 experts from member companies, will now review and shortlist the most deployable technologies, offering shortlisted start-ups access to key industry resources and networks.

Germany: Heidelberg Materials has begun work on the GeZero project at its Milke plant in Geseke. The €500 million project will implement carbon capture and storage (CCS) technology to prevent the release of CO₂, instead capturing and storing it under the North Sea. According to the Westfälische Rundschau, the project has secured €191m in funding from the EU, with Heidelberg Materials covering the remaining amount. The company anticipates completing the plant conversion by 2029, with interim CO₂ transport via rail and potential future pipeline connections. According to the company, around 700,000t/yr of CO₂ is currently produced by the plant.

There had been potential changes in project partnerships due to the sale of BASF subsidiary Wintershall Dea, which was to provide the transport and storage solutions, to Harbour Energy. However, plant manager Steffen Gajewski expects that planning for the conversion of the plant will be completed in 2025, when the new oxyfuel kilns to capture the CO₂ will be ordered and installed.

Germany: Holcim is investing a three-figure million sum into its cement plant in Lägerdorf, Steinburg, according to the Segeberger Zeitung. The plant will employ a second-generation oxyfuel kiln line to increase the concentration of CO₂ in the flue gas during clinker production. The project aims to capture 1Mt/yr of CO₂. The new kiln line is expected to be operational by 2029.

State Secretary for Energy, Joschka Knuth, said "The decarbonisation of Holcim is a very important signal for the entire industrial location of Germany."

Canada: Heidelberg Materials North America has announced a new front end engineering design (FEED) contract for its Edmonton carbon capture, utilisation, and storage (CCUS) project. This involves MHI Low Carbon Solutions Canada (MHI-LCSC) and Kiewit Energy Group who will collaborate on the carbon capture technology at the plant. The FEED study will leverage MHI's Advanced KM CDR Process, which uses the KS-21 solvent. The Edmonton plant aims to capture 1Mt/yr of CO₂.

Vice President at Kiewit, Rob Medley, said "Heidelberg Materials is taking a major step towards decarbonising hard to abate industries by deploying innovative and effective carbon capture technology."

Heidelberg Materials announced this week that it is preparing to close its integrated cement plants at Beffes and Villiers-au-Bouin in France by October 2025. It framed the restructuring as a response to ‘a significant decline in cement sales in France’ and a plan to focus on low-carbon products. Unfortunately, local media reported that around 170 jobs will be lost at the two sites. The company says it is looking at ‘socially acceptable solutions’ including redeployment to other locations in the country.

Investment has been forthcoming from Heidelberg Materials France in recent years. It reminded everyone that it initiated a Euro400m scheme at its France-based subsidiary Ciments Calcia in late 2020. Most of this was earmarked towards a new production line at the Airvault plant, which is currently being built. Other schemes at the Beaucaire, Bussac-Forêt and Couvrot integrated plants followed. More recently, Heidelberg Materials launched a carbon capture, utilisation and storage (CCUS) project at Airvault, part of the GOCO2 initiative, with the aim of starting initial capture in 2030 with full 1Mt/yr capture planned later. What the company didn’t mention though was at the time of that 2020 investment it was also preparing to convert the integrated Gargenville plant into a grinding unit, stop white cement production at its Cruas plant with the intention of turning the site into a terminal and it wanted to reduce its workforce by around 140. To be fair to Heidelberg Materials though, it did have the same goal of reducing its specific net CO₂ emissions. The added detail this week was that the group aims to generate half of its revenue from sustainable products that are either low-carbon or circular by 2030.

Heidelberg Materials France is not alone with its ambitions for low-carbon products. Holcim notably opened in early 2023 what it said was the first calcined clay unit in Europe at its Saint-Pierre-la-Cour cement plant. Heidelberg Materials then followed in May 2023 with the announcement of a calcined clay project at its Bussac-Forêt cement plant. Other clay projects from Vicat, NeoCem and Neo-Eco have been reported since then. The other prominent France-based blended cement producer that has steadily been building its business in recent years is Hoffmann Green Cement. More general plant upgrade projects that are also worth mentioning include Eqiom’s (CRH) upgrade to its Lumbres plant in February 2024 and the ignition of a new kiln at Lafarge France’s Martres-Tolosane plant in October 2023. Both of these projects have been framed as driving sustainability.

Heidelberg Materials’ assessment about the poor state of the cement market has been confirmed by local media. Sales reportedly started falling in 2022, were down by 6% year-on-year in 2023 and further downward pressure is expected in 2024. Production data shown in Graph 1 above released by France Ciment, the national cement association, doesn’t really show what has been happening with sales. Over the last 20 years production hit a high of around 22Mt in the mid-2000s before settling around 16 - 17Mt/yr from 2015 onwards. The more telling trend, perhaps, has been the increase in CEM II blended cements from 50% in 2012 to 64% in 2022. Cement production may have stayed roughly the same over the last decade but it is using less clinker than it used to. Hence the pressure on companies like Ciments Calcia to reduce clinker capacity.

A further cost pressure facing cement producers in France is the impending end to the price cap on electricity scheduled by the end of 2025. The government enacted the scheme in late 2021 at the end of the Covid-19 pandemic, but then carried on as energy prices spiked following the Russian invasion of Ukraine. France Ciment lobbied in August 2023 for further protection for the sector using the argument that decarbonisation was not possible without electricity available for a reasonable price. It added that decarbonising the cement sector in France with carbon capture would cost around Euro3.5bn. Electricity prices started rising in February 2024 as part of the government’s phase out of the scheme.

Finally, 17 people were arrested on 5 April 2024 in connection with a demonstration at Lafarge France’s Val-de-Reuil ready-mixed concrete plant in Eure. Environmental activists reportedly trespassed on the site, according to local press, causing an estimated Euro450,000 in damages with acts such as spraying foam into machinery, ripping up bags of cement, breaking windows and more. The activists presented their actions as a response to both the environmental impact of cement and concrete production and the ongoing legal allegations about Lafarge’s actions in Syria in the early 2010s. Lafarge France’s La Malle integrated plant was also similarly targeted in December 2022 when around 200 activists stormed the site and caused damage to machinery and property. Lafarge’s response at the time was to remark that there was a feeling of misunderstanding given that the La Malle plant was piloting various decarbonisation methods.
All of this presents a febrile picture of the cement sector in France. Sales are down, electricity costs are set to go up and producers are switching to low-carbon cement products. Alongside this they are also closing clinker production plants but are also investing in new decarbonisation projects. At the same time environmental protestors have also been targeting cement and concrete plants and Lafarge’s association with its former actions in Syria appear to have made it more of a target than the other manufacturers. It is unsurprising then that Holcim, the parent company of Lafarge France, has raised the risk of damage to the group’s reputation, with both the general public and investors, should it fail to meet its targets. Reaching net zero was never going to be easy but setting unrealistic targets is increasingly not an option.

The US Department of Energy (DOE) announced a US$1.6bn investment in the cement sector this week. The funding was part of a total of US$6bn for 33 projects in over 20 states to decarbonise energy-intensive industries also including chemicals and refining, iron and steel, aluminium and metals, food and beverages, glass, process heat applications and pulp and paper. The DOE was keen to link the money to “the President’s Bipartisan Infrastructure Law and Inflation Reduction Act.” Politics is never far away it seems! The projects are part of the Industrial Demonstrations Program, managed by DOE’s Office of Clean Energy Demonstrations (OCED).

Table 1: Summary of US Department of Energy funding announced on March 2024 to decarbonise cement and concrete production

Table 1 above shows the main approaches each of the projects aim to use. The two most expensive ones involve carbon capture and sequestration (CCS) at Heidelberg Materials US’ Mitchell cement plant in Indiana and National Cement’s Lebec plant in California respectively. In a complimentary press release Chris Ward, the CEO of Heidelberg Materials North America, said “This substantial federal funding investment will help create the first full-scale deployment of carbon capture and storage on a cement plant in the US.” The proposed CCS unit at the plant will capture around 2Mt/yr of CO₂ from 2030. If Ward’s forecast is accurate (and no one beats them to it), then Heidelberg Materials will likely have set up the first full-scale CCS units at cement plants in both North America and Europe. This will be a significant achievement. The National Cement project, by contrast, is a mixed bag of approaches to decarbonising cement production that follows the multi-lever approach advocated for in many of the industry net-zero roadmaps. It intends to use agricultural by-products such as pistachio shells, as alternatives fuels to lower the fuel-based emissions, calcined clay to lower the clinker factor and CCS to capture the remaining 950,000t/yr of CO₂ emissions.

The other projects either involve using calcined clay or substituting limestone with calcium silicate. The Summit Materials proposal is noteworthy because it aims to build four clay calcination units in locations in Maryland, Georgia and Texas. None of these appear to be near Summit’s (or Cementos Argos’) cement plants. This suggests that the company may be intending to use calcined clay in ready-mixed concrete production. The Roanoke Cement Company calcined clay project will be baseEuropead at its cement plant in Troutville, Virginia.

The remaining two grant recipients, Brimstone and Sublime Systems, will both test the companies’ different methods of manufacturing cement by using calcium silicate instead of limestone. Brimstone’s method produces ordinary Portland cement (OPC) and supplementary cementitious materials (SCM). The company said in July 2023 that its OPC met the ASTM C150 standards. However, the company has released less information about its actual process. Sublime Systems’ uses an electrolysis approach to create its ASTM C1157-compliant cement. It calls this ‘ambient temperature electrochemical calcination.’

Investment on the same scale of the DOE has also been happening in Europe. In July 2023, for example, the European Commission announced an investment of Euro3.6bn in clean tech projects to be funded from the proceeds of the European Union emissions trading scheme (ETS). This was the third call for large-scale projects following previous announcements of recipients in 2021 and 2022. Euro1.6bn of the third call funding went towards cement and refining projects including five cement and lime projects in Belgium, Croatia, Germany and Greece. The money granted for each of these schemes was in the region of Euro115 - 235m.

Both the US and Europe are throwing serious finance at the cement industry to try and kickstart the various pathways towards net zero. They are also doing it in different ways, with the US aiming to boost its economy by onshoring sustainable industry, and Europe hoping to fund its approach via carbon taxation. Government-driven decarbonisation investment for cement in other large countries and regions around the world appears to be lagging behind the US and Europe but these may spring up as net zero targets are set, roadmaps drawn up and government policy formulated. These places could also benefit from watching what works and does not work elsewhere first. Back in the US and Europe the next tricky part of this process will be bridging the gap between government subsidy and commercial viability.

US: The US Department of Energy has selected four cement producers to receive funding under the Bipartisan Infrastructure Law and the Inflation Reduction Act.

Heidelberg Materials US secured up to US$500m for its planned 2Mt/yr carbon capture project at the Mitchell cement plant in Indiana. National Cement also received up to US$500m, for its Lebec Net Zero limestone calcined clay cement (LC3) project in California. Summit Materials received up to US$216m for a series of clay calcination projects in Georgia, Maryland and Texas. Lastly, Roanoke Cement will receive up to US$61.7m for an LC3 project at its Troutville cement plant in Virginia.  These projects also involve developing a training, education and certification consortium in the cement sector.

Portland Cement Association (PCA) president and CEO Mike Ireland said "This funding is a welcome acknowledgement from the government that America's cement manufacturers are taking ambitious and significant steps toward reaching carbon neutrality. This will move the needle closer to achieving what industry considers the 'heavyweight' of carbon solutions: carbon capture utilisation and storage (CCUS). Once established nationwide, CCUS will greatly accelerate cement manufacturers' charge toward net zero."

Senior vice president of government affairs Sean O'Neill added “From passage of the Bipartisan Energy Act of 2020 to securing funding through the Inflation Reduction Act and the Infrastructure Investment and Jobs Act, today's announcement is another major milestone in the cement industry's decarbonisation efforts. The PCA is committed to continuing to work with policymakers to ensure the regulatory environment facilitates rather than impedes these and future investments.
