Decarbonising in the US
04 June 2025A 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projects, Lebec and Mitchell accounted for US$1bn (27%) of a total US$3.73bn in allocated funds that have now been withdrawn.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: The US Department of Energy may end the Industrial Demonstrations Program that aims to decarbonise hard-to-abate industries like cement, placing up to US$6bn in federal grants at risk, according to Canary Media. This includes an eventual US$500m in Heidelberg Materials North America’s Mitchell cement plant carbon capture project in Indiana. The project is reportedly at risk after 'significant' staff cuts at the Department of Energy.
The senior vice president of sustainability and public affairs for Heidelberg Materials North America, David Perkins, said that the company was ‘uncertain’ and that ‘coordination and communications [had] changed’. He added that the company is still submitting reports for the grant to the Department of Energy and exploring alternative funding sources.
Terra CO2 raises US$82m to scale sustainable cement technology
20 February 2025US: Terra CO2 has raised US$82m in Series B funding from investors including Eagle Materials, GenZero and Just Climate. The company will build its first commercial facility in Dallas-Fort Worth, Texas, in partnership with Asher Materials.
With the help of Eagle Materials, the company will establish multiple 240,000t/yr plants across North America. The US Department of Energy has also awarded Terra CO2 with a grant of US$52.6m for a second commercial facility. The producer has begun concrete trials of its Opus Zero cement-free product, designed to completely replace ordinary Portland cement in concrete. It will complete a second funding round in the first quarter of 2025.
“This strategic funding from the world’s leading climate funds and industry partners validates our approach to practical cement decarbonisation at commercial scale,” said Bill Yearsley, CEO of Terra. “As we break ground on our first full-scale plant in Texas, their support enables us to accelerate deployment across North America and establish an early footprint in Europe.”
US: The US Department of Energy's (DOE) Office of Fossil Energy and Carbon Management has selected Cemex's Knoxville cement plant in Tennessee as the site for a carbon capture, removal and conversion test centre. The project is part of a US$101m initiative shared among five projects that aim to decarbonise cement plants and power facilities.
Cemex, in collaboration with the University of Illinois Urbana-Champaign (UIUC) and a coalition of US cement producers, will develop the conceptual design, business, technical and managerial frameworks for the test centre under Phase 1. Phase 2 will involve constructing and operating the centre to evaluate advanced carbon management systems.
Jaime Muguiro, president of Cemex US, said “While we are making steady progress, the cement industry has the opportunity to accelerate the pace of our decarbonisation even more. I am excited that our Knoxville cement plant has been selected as the host site for the carbon capture test centre. Through collaboration and continuous innovation with the University of Illinois and industry peers, Cemex is committed to advancing decarbonisation solutions.”
US: The Department of Energy’s (DOE) Office of Fossil Energy and Carbon Management has announced US$101m in funding for five projects to establish carbon capture, removal, and conversion test centres for cement plants and power facilities. The test centres aim to cost-effectively research and evaluate technologies to capture and convert CO₂ into products from utility and industrial sources, or by removing CO2 from the atmosphere. The initiative aims to reduce CO₂ emissions, promote sustainable technologies and create job opportunities.
Notable projects include the University of Illinois in Urbana, which plans to design a test centre to evaluate carbon management technologies for the cement industry, and Holcim US, which intends to establish a Cement Carbon Management Innovation Centre at its Hagerstown facility in Maryland.
Brad Crabtree, assistant secretary for Fossil Energy and Carbon Management, said “Carbon management technologies such as carbon capture can significantly reduce emissions from fossil energy use and key industrial processes, like cement production. By investing in test centres, we are helping reduce barriers to commercial-scale deployment of carbon capture, conversion and removal technologies that will ultimately help reduce pollution and create jobs.”
Calix’s Leilac projects secure DOE funding
10 January 2025US: The US Department of Energy (DOE) has awarded funding for two Leilac projects to conduct preliminary front-end engineering design (pre-FEED) studies, subject to final negotiations.
A project at Roanoke Cement Company in Virginia, led by Titan Group in partnership with Leilac, Amazon and Virginia Tech, received US$1.49m. It aims to capture over 500,000t/yr of CO₂ from cement Scope 1 emissions using Leilac’s technology.
A project at Mississippi Lime Company in St Louis, Missouri, in partnership with Leilac, Industrial Ally and Nuada, received US$1.5m. It seeks to achieve net-zero lime manufacturing by integrating Leilac’s CO₂ capture technology with Nuada’s carbon capture system for combustion emissions.
Calix CEO Phil Hodgson said “We look forward to concluding the grant agreements and developing these exciting projects that have the potential to demonstrate industry-leading solutions to produce both low-carbon cement and lime at commercial scale.”
Portland Cement Association asks US Department of Energy to consider alternative fuels
23 December 2024US: The Portland Cement Association (PCA) has asked the US Department of Energy to add alternative fuels to its Material Circularity Framework. It said that alternative fuels in the cement manufacturing process are better for the environment than the use of traditional fuels and that it diverted a significant amount of materials from landfill. The PCA said that the DOE’s Framework “…should address how to promote circularity through alternative fuels and replacement of raw materials to promote reducing greenhouse gases emissions.”
The DOE released its draft strategic framework ‘Circularity for Secure and Sustainable Products and Materials’ in October 2024. It asked for feedback from stakeholders by mid-December 2024. The framework is intended to identify opportunities and challenges to use circularity to decarbonise industry, secure supply chains, benefit communities and create jobs. The draft mentions recycling concrete and generating secondary cementitious materials from recovered material streams.
Vicat subsidiary to develop Lebec Net Zero project with DOE funding
16 December 2024US: Vicat subsidiary National Cement Company of California has signed a cooperative agreement with the US Department of Energy (DOE) Office of Clean Energy Demonstrations to develop the Lebec Net Zero (LNZ) project at its Lebec cement plant in California.
The agreement commits up to US$500m, covering up to 50% of the Phase one cost. The project includes constructing a CO₂ sequestration facility with a 0.95Mt/yr capacity, enabling the plant to capture ‘almost all’ of the plant’s emissions. It will also increase alternative fuel use from locally sourced biomass and reduce the plant’s clinker factor by producing calcined clay-based cement. The plant will reportedly produce carbon-neutral cement.
The first step will be to conduct a preliminary engineering study and establish a community advisory body in charge of relations with local communities. Phase one will run through the first quarter of 2026.
US: Sublime Systems has completed negotiations with the US Department of Energy for a US$87m grant to build a ‘clean’ cement manufacturing plant in Holyoke, Massachusetts. The company will now commence site engineering, design and permitting. The Holyoke plant will demonstrate full-scale operations of its cement manufacturing process when production begins in 2026. Sublime Systems expects to create 70 - 90 jobs once its new plant is operational.
