A week ago, there were two fully-financed cement plant carbon capture, utilisation and storage (CCUS) projects underway in the US.¹ Now, there aren’t.

Projects to decarbonise National Cement Company’s Lebec, California, plant and Heidelberg Materials North America’s Mitchell, Indiana, plant were each set to receive up to US$500m in US Department of Energy (DoE) funding on a one-for-one basis with private investments. The projects were to include eventual 950,000t/yr (Lebec) and 2Mt/yr (Mitchell) carbon capture installations. Additionally, the Lebec plant was to transition to limestone calcined clay cement (LC3) production and the use of alternative fuels (AF), including pistachio shells. Both were beneficiaries of the DoE’s US$6bn Industrial Demonstrations Program (IDP), touted by former US Secretary of Energy Jennifer Granholm as ‘Spurring on the next generation of decarbonisation technologies in key industries [to] keep America the most competitive nation on Earth.’ Disbursement of funding under the programme was frozen by executive order of President Trump in January 2025.^{2, 3}

On 30 May 2025, Trump’s Secretary of Energy announced that the government in which Granholm served had approved spending on industrial decarbonisation without a ‘thorough financial review.’ He cancelled remaining project funding in signature Trumpian style, in list form.⁴ Among 24 de-funded projects, Lebec and Mitchell accounted for US$1bn (27%) of a total US$3.73bn in allocated funds that have now been withdrawn.

It's hard not to feel sorry for the management of the Lebec and Mitchell plant and the teams that had been working to deliver these projects. Heidelberg Materials has yet to comment, though CEO Dominik von Achten was in North America in late May 2025. National Cement Company parent Vicat, meanwhile, conceded the setback with a strong statement of its commitment to CO₂ reduction, to 497kg/t of cementitious product globally.⁵ There was a diplomatic edge to the statement too, however. Echoing the Secretary of Energy, Vicat said that its target remains ‘solely based on existing proven technologies, including energy efficiency, AF substitution and clinker rate reduction’ – as opposed to ‘any technological breakthroughs’ like carbon capture. There are currently no public details of possible back-up financing arrangements for these projects; for now, the best guess at their status is ‘uncertain.’

Alongside these group’s local subsidiaries, another organisation that has to do business daily with the DoE is the American Cement Association (ACA). President and CEO Mike Ireland has continually acknowledged the complex needs of the government, while stating the association’s case for keeping support in place. With regard to these funding cuts, Ireland’s emphasis fell on the latter side: “Today’s announcement is candidly a missed opportunity for both America’s cement manufacturers and this administration, as CCS projects have long been supported by bipartisan members in Congress and bipartisan administrations.”⁶ He reasserted the ACA’s understanding that carbon capture aligns with the administration’s strategy to bolster domestic manufacturing and innovation.

The early 2020s heyday of US carbon capture was founded on gradual, consensus-based politics – unlike its demise. Table 1 (below) gives a non-exhaustive account of recent and on-going front-end engineering design (FEED) studies and the funding they received:

Additionally, MTR Carbon Capture, which is executing a carbon capture pilot at St Marys Cement’s Charlevoix plant in Michigan, previously received US$1.5m in Fossil Energy Research and Development funding towards a total US$3.7m for an unspecified cement plant carbon capture study.¹⁰

Market researcher Greenlight Insights valued industrial decarbonisation initiatives under the Office of Clean Energy Demonstrations (ODEC – the now defunct DoE office responsible, among other things, for the IDP) at US$65.9bn in cumulative returns in April 2025.¹¹ The government has yet to publish any account of how it might replace this growth, or the 291,000 anticipated new jobs that would have come with it. Given all this (along with the extensive financial and technical submissions that accompanied each project), the issues raised by the DoE are presumably budgetary, or else founded in a perception of CCUS as essentially uneconomical.

Carbon capture is very, very expensive. A fatuous reply is that so is climate change, just with a few more ‘verys.’ Hurricane Ian in September 2022 cost US$120bn, more than enough to fund carbon capture installations at all 91 US cement plants, along the lines of the former Lebac and Mitchell agreements.¹² Unlike climate change, however, carbon capture remains unproven. Advocates need to continually justify taxpayer involvement in such a high-risk venture.

At its Redding cement plant in California, Lehigh Hanson successfully delivered a funding-free FEED study, with its partner Fortera raising US$85m in a Series C funding. This presents an alternative vision of innovation as fully-privatised, in which the government might still have the role of shaping demand. This is borne out in the IMPACT Act, a bill which ‘sailed through’ the lower legislature in March 2025.¹³ If enacted, it will empower state and municipal transport departments to pledge to buy future outputs of nascent reduced-CO₂ cements and concretes.

A separate aspect of the funding cancellation that appears decidedly cruel is the targeted removal of grants to start-ups. Two alternative building materials developers – Brimstone and Sublime Systems – were listed for a combined US$276m of now vapourised liquidity. Both are commercially viable without the funding, but the effect of this reversal – including on the next generation of US innovators who hoped to follow in their footsteps – can only be chilling. As non-governmental organisation Industrious Labs said of the anticipated closure of the ODEC in April 2025: “We may see companies based in other geographies start to pull ahead.”

Heidelberg Materials’s Brevik carbon capture plant came online in June 2025, 54 months after the producer secured approval for the project. The term of a presidency is 48 months. This probably means that producers in the US will no longer see CCUS as a viable investment, even under sympathetic administrations.

Even as government funding for CCS flickers from ‘dormant’ to ‘extinct,’ the sun is rising on other US projects. Monarch Cement Company commissioned a 20MW solar power plant at its Humboldt cement plant in Kansas on 27 May 2025. The global momentum is behind decarbonisation, even if economics determines that it will only take the form of smaller-scale mitigation measures at US cement plants into the medium-term future. We can hope that these, at least, might include the AF and LC3 aspects of National Cement Company’s plans at Lebec.

US: The Trump administration has cancelled a US$500m grant awarded in December 2024 to National Cement in California for the conversion of its Lebec cement plant into the state’s first net-zero cement facility. The project, valued at US$891m, aimed to switch to limestone calcined clay cement and use agricultural waste as fuel, with CO₂ captured for permanent underground storage, according to the Bakersfield Californian newspaper. It was expected to create 20 - 25 permanent jobs. The US Department of Energy (DOE) said the project was among 24 grants worth US$3.7bn cancelled due to failure “to advance the energy needs of the American people,” and cited economic infeasibility and poor return on taxpayer investment.

US Secretary of Energy Chris Wright said that the previous administration “failed to conduct a thorough financial review before signing away billions of taxpayer dollars.”

Executive director Steven Nadel of the American Council for an Energy-Efficient Economy said “Choosing to cancel these awards is shortsighted, and I think we're going to look back at this moment with regret.”

The project was one of 33 cement, steel and aluminium decarbonisation projects awarded DOE grants in 2023. The project turned up on an April 2025 list of 39 projects the DOE's Office of Clean Energy Demonstrations was considering terminating.

US: It is rumoured that the Trump administration is ‘rethinking’ a US$500m subsidy awarded to National Cement’s Lebec plant in California for a carbon capture and storage project, which had formerly been awarded by the previous Biden administration. The plans intend to make the plant California’s ‘first net zero cement plant’ in line with a 2021 state law to make all cement used in California be net-zero by 2045. It is expected to create 20-25 jobs.

"No final decisions have been made and multiple plans are still being considered," wrote government spokeswoman Andrea Woods in an email to press. She did not mention the cement plant project specifically, nor question the authenticity of a series of spreadsheets, reported on by the US press, which appear to show federal grants for decarbonisation projects that may be being reconsidered.

President Trump has expressed scepticism over his predecessor's focus on addressing climate change, including the use of public funds. National Cement says that it has not been contacted by the government about the project.

Rwanda: Kenya-based National Cement subsidiary Cimerwa has announced the appointment of Mangesh Verma as its CEO. He succeeds James Oduor, who oversaw the company’s acquisition by National Cement and its acquisition of Prime Cement.

Verma previously served as general manager commercial and operations for Kenya-based food producer United Millers. He previously occupied management positions in various companies in Kenya and India. He has an MBA from Dr RML Avadh University and a bachelor’s in Botany, Zoology and Chemistry from the University of Allahabad, both in India.

Kenya-based East African Portland Cement (EAPCC) made the news this week with the reopening of the company’s Athi River cement plant after a month-long shutdown. The closure was conspicuous because the company is gradually working towards increasing the integrated plant’s production capacity. The first phase of the maintenance and upgrade project saw the replacement of the production line’s kiln shell in September 2022. The current aim is to increase the unit’s cement production capacity to 1Mt/yr by mid-2026. The recent shutdown appears to have been a more normal annual renewal and repair job but EAPCC has used it as a promotional opportunity. Notably, a spokesperson for EAPCC described clinker as the “new gold” in a recent video explaining what was going on.

It’s an improvement on the financial trouble EAPC found itself stuck within in the late 2010s before the government ended up taking a controlling share in the cement producer. On this front local media reported in July 2023 that the government had found a 'strategic investor' to buy a 30% stake in the company. Nothing more has been said on this topic since then though.

The highlighting of the recent shutdown is likely to be a public relations exercise intended to project stability, but that focus on clinker is telling given that the government introduced its Export and Investment Promotion Levy in July 2023. This legislation imposed a 17.5% fee on imported clinker in order to encourage the local industry. Cement producers that rely on imported clinker - including Rai Cement, Bamburi Cement, Savannah Cement, Ndovu Cement and Riftcot - attempted to lobby against the levy but it remains in place. This business environment helps to explain EAPCC’s renewed focus on clinker production.

One company that stands to benefit from the levy is National Cement, producer of the Simba Cement brand and a subsidiary of Devki Group. It made the news at the start of April 2024 when its subsidiary Cemtech commissioned a 6000t/day clinker plant at Sebit in West Pokot. National Cement already operates an integrated plant near Athi River, south of Nairobi. However, hot on the heels of the West Pokot plant, it is already considering building another integrated plant in the north of Kitui County, to the east of Nairobi. As reported in the local press this week, Cemtech has submitted an environmental impact assessment for the project to the local authorities.

The country has two other clinker producers: Holcim subsidiary Bamburi Cement and Mombasa Cement. The former company announced at the end of 2023 that it had signed a contract to build solar plants at its integrated plant in Mombasa and its grinding plant in Nairobi. The deal was framed as a money saver but additionally it may have been in response to a less than reliable local grid. It also said that it was removing Ordinary Portland Cement (OPC) from its product line from the start of 2024. This move challenged expectations about sustainability initiatives outside of richer countries. Yet, considering how Bamburi Cement argued against the clinker levy, there might have been some commercial thinking here too in order to sell products that use less clinker. Finally, despite completing its divestment of Uganda-based subsidiary Hima Cement for US$84m in March 2024, Bamburi Cement reported a loss of US$2.99m in 2023 compared to a profit of US$1.36m in 2022. Although it reported a rise in turnover and operating profit, it appears that taxes and legal costs related to the sale of Hima dragged the company into a loss.

It’s been a difficult business environment in Kenya over the last decade given the number of companies that have faced serious financial difficulties. This list includes ARM Cement, EAPCC and Savannah Cement. The last of these companies, Savannah Cement, is currently in administration and is trying to sell its integrated plant. Yet, rolling annual cement production in Kenya has remained above 9.5Mt/yr since early 2022. The government is sticking to promoting local clinker production, and companies like Bamburi Cement, EAPCC and National Cement are making investments of varying scales. The focus, for now at least, is on clinker production in Kenya.

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.

Rwanda: South Africa-based PPC has completed the sale of its 51% stake in the Rwandan cement producer to Kenya-based Devki Group subsidiary National Cement, for US$42.5m. The divestiture advances PPC's strategic exit of Central and East Africa. As a result, the group's financial position is now cash positive. It had previously reduced its debt by 50% to US$20.3m from US$40.7m between March 2020 and September 2023.

PPC CEO Matias Cardarelli said "I am pleased with the timely completion of the sale of our stake in Cimerwa. The disposal allows us to focus on our core Southern African markets, where we see opportunities to drive improved profitability and secure a more sustainable return on capital."

Rwanda: CIMERWA increased its sales by 12% year-on-year to US$82.5m during the 2023 financial year, which ended on 30 September 2023. Its profit also grew, by 19% to US$16.1m. KT Press news has reported that the National Cement subsidiary, at that time a subsidiary of South Africa-based PCC, attributed the growth to its optimisation of production processes, cost savings initiatives and revamped route-to-market model for both the domestic and export markets.

Chief executive officer James Oduor said "We are very proud of this past year's financial performance. We remain very optimistic that the optimisation of selling prices as well as distribution channels for both domestic and export markets will translate to an even better performance in the coming year." He added "We have put in place a strategy and roadmap to guide actions around environmental, social and governance (ESG) and remain steadfast in our commitment to continually deliver superior value to our customers, shareholders and the nation as whole, all while fulfilling on our promise to continue strengthening Rwanda."

Rwanda: Kenya-based Devki Group subsidiary National Cement signed a deal to acquire CIMERWA from International Holdings Proprietary Limited, a subsidiary of South Africa-based PPC, and minority shareholders on 17 November 2023.

KTPress News has reported that CIMERWA’s chair, Regis Rugemanshuro, said “We look forward to welcoming National Cement as our new shareholder. We are confident that they have the financial and technical resources required to support CIMERWA’s growth and expansion in line with our vision and their ambitions in the region.”

Narendra Raval, chair of Devki Group, said “We are committed to a long-term strategic partnership with CIMERWA. We believe in the potential for this business and its people and are excited by the opportunity to support infrastructure development in the region in line with our strategic expansion ambitions.”
