Decarbonising the cement sector in the US, March 2024
27 March 2024The 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).
Company | State | Funding | Scale | Method |
Heidelberg Materials US | Indiana | US$500m | Full | CCS |
National Cement | California | US$500m | Full | Alternative fuels, calcined clay, CCS |
Summit Materials | Georgia, Maryland, Texas | US$216m | Demonstration | Calcined clay |
Brimstone Energy | TBD | US$189m | Commercial | Raw material substitution |
Sublime Systems | Massachusetts | US$87m | Commercial | Raw material substitution |
Roanoke Cement | Virginia | US$62m | Demonstration | Calcined clay |
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.

Fujairah Cement faces losses
27 March 2024UAE: Fujairah Cement has reported accumulated losses reaching over a third of its capital, primarily due to inflation and decreased revenue, according to Zawya. The total accumulated losses for the 2023 financial year stood at US$35.5m, equating to 36.68% of the company's capital, as disclosed on the Abu Dhabi Securities Exchange.
The company attributes the increase in losses to various factors, including the rising cost of coal and energy, lower clinker selling prices, a decline in revenue, and higher logistics and finance costs. The company is currently in advanced talks to appoint a renowned financial advisor for assistance in restructuring and exploring other potential options to mitigate these losses.
A separate disclosure highlighted that the major challenge faced during the year was the escalated production costs, primarily driven by increased coal and fuel prices.
Ecocem launches low-carbon ACT cement range
27 March 2024France: Ecocem has launched a new low-carbon advanced cement technology (ACT) cement, aiming for widespread adoption in European construction projects. The ACT range promises a clinker concentration of 20%, lower than the current norm of 35% minimum.
Jean-Christophe Trassard, Director, Marketing of Sustainable Innovation, said "We achieve competitive rates by controlling granularity, the fineness of grinding and admixtures. We have also greatly developed our thinking on the addition of additives in our formulations, which required more than fifteen years of R&D and the filing of six patents."
This product contains locally sourced additives, with the capability to adapt mixes to regional availability. The ACT cement is expected to reduce water usage by one-third compared to conventional concrete. An ACT-based concrete reportedly emits 198kg CO₂/t, a substantial reduction from the 614kg CO₂/t for standard concrete in France.
Gaining market entry for ACT required European technical evaluation and European assessment document certification, currently pending in the EU Official Journal. Trassard added, "As we are dealing with clinker rates below the standards, we had to go through this certification, which gives us a very good passport for the European markets. However, local administrative variations will have to be carried out subsequently."
In France, Ecocem has already applied for ATEX certification to facilitate deployment of the ACT range, expected later in 2024. Ecocem aims to include the ACT range in standard norms by 2026.
Afghan government targets 4.5Mt/yr capacity across Injil, Jabal Saraj and Shur Andam cement plants
27 March 2024Afghanistan: The government says that contracts worth US$450m have been concluded for the expansion of three Afghan cement plants to 1.5Mt/yr capacity each. Local companies will carry out the expansions, at the Injil cement plant in Herat and the Shur Andam cement plant in Kandahar, while a Qatar-based company will carry out the Jabal Saraj cement plant in Parwan. TRT World News has reported that the Afghan Ministry of Mines and Petroleum expects Afghanistan to become self-sufficient for cement after the new capacity joins existing capacity at the Jabal Saraj cement plant and the Ghori cement plant in Baghlan. These two plants reportedly produce 330,000t/yr of cement, less than 10% of domestic demand.
CRH sells UK lime business
27 March 2024Ireland: CRH says that it has completed the sale of its UK lime business. The sale concludes the second phase of the group’s divestment of its lime operations in Europe, first announced in November 2023. The total sale value of CRH’s European lime business is US$1.1bn.
Caribbean Cement Company to expand production
27 March 2024Jamaica: Caribbean Cement Company's first phase of its expansion project is set for completion in 2025. The expansion will increase cement production by 30%.
Managing director Jorge Martinez said "When completed, this project will further reduce our CO₂ emissions and deliver increased output from 2600 to 2850t/day of clinker to meet the increased local demand for cement. We will also have the capacity to explore options for exporting to other countries within the Caribbean community. These exports will benefit Jamaica’s economy through foreign currency income."
The US$40m plant expansion in Rockfort, Kingston is financed by the company, with 150 workers already on the project. The expansion was announced in 2022 and aims to strengthen Jamaica's cement industry, reduce import reliance and support the regional construction sector. It will also support parent company Cemex's sustainability targets, including CO₂ emission reduction and optimisation of heat consumption in cement production, as part of its Future in Action programme.
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.
