Holcim launches Eco2Fly carbon capture project
09 April 2025Spain: Holcim, IGNIS P2X and Exolum have launched Eco2fly, a project to convert industrial CO₂ emissions into sustainable aviation fuel at Holcim’s Villaluenga de la Sagra plant in Toledo. The facility will capture over 700,000t/yr of CO₂ from the plant’s cement production process and convert it into 100,000t/yr of sustainable aviation fuel using ‘green’ hydrogen. The remaining CO₂ will be stored in geological repositories. Over its first 10 years, the project will reportedly avoid more than 6.5Mt of CO₂ emissions.
Denmark: Air Liquide and Cementir Holding, via its Danish subsidiary Aalborg Portland, have signed the European Innovation Fund grant agreement for the ACCSION project at the Aalborg cement plant. The project aims to reduce the plant’s CO₂ emissions by 1.5Mt/yr, with the captured CO₂ transported via pipeline to onshore CO₂ storage facilities.
The value of the Innovation Fund grant is €220m, fully financed by the EU Emissions Trading System.
Cement Industry Federation urges carbon border tax
27 March 2025Australia: The Australian government’s ‘unwillingness’ to impose a carbon levy on imported cement, lime and clinker is threatening decarbonisation efforts and could cost up to 1400 jobs, according to the Financial Review.
The Cement Industry Federation, which represents local producers Adbri, Boral and Cement Australia, has said that the absence of a carbon levy on imports from countries with less robust climate commitments paved the way for the offshoring of local manufacturing, a process known as ‘carbon leakage’.
It said “Not addressing the issue of carbon leakage in a timely manner will be detrimental to Australian cement and lime manufacturing and could lead to the unnecessary loss of key Australian cement and lime facilities."
Imports currently account for over 40% of domestic clinker consumption and originate largely from southeast Asia. In 2023, an energy expert was appointed by the government to assess the feasibility of an Australian carbon border adjustment mechanism, with a final recommendation expected to be delivered in 2024. However, only an interim report was released in November 2024, with the final advice now reportedly due after the election in May 2025.
Japan: Mitsubishi UBE Cement Corporation has started a commercial-scale demonstration test using ammonia as a heat energy source in a cement kiln and calciner at Ube cement plant.
The project, supported by Yamaguchi Prefecture’s 2023 Carbon Neutral Complex Development Promotion Subsidy, follows an ammonia co-combustion test in 2023. In collaboration with UBE Corporation, a test facility for ammonia co-firing was installed.
The company has set a target of replacing 30% of its coal consumption with ammonia in the cement kiln, with similar levels targeted for the calciner by the end of the 2025 financial year. Mitsubishi UBE Cement is also planning further ammonia combustion tests with post-consumer plastics and other materials as energy sources.
Europe: 77 decarbonisation projects (including 14 for the cement sector) have signed grant agreements under the Innovation Fund 2023 Call (IF23), following the announcement of results in October 2024. The cement projects, spanning nine European countries, will begin operations between 2025 and 2029.
The funding, sourced from the EU Emissions Trading System, provides grants ranging from €4.4m to €234m, supporting projects expected to avoid 118Mt of CO₂. The total 77 projects funded have the potential to reduce emissions by around 398Mt of CO₂ equivalent over their first 10 years of operation. The projects funded in the cement industry mostly involve carbon capture and storage (CCS). Among the selected CCS projects are Carbon2Business in Germany, Olympus in Greece, Go4Zero in Belgium and Cementir’s Accsion project in Denmark.
Canada: Heidelberg Materials North America has secured government support from Innovation, Science and Economic Development Canada (ISED) for its carbon capture, utilisation and storage (CCUS) project at its Edmonton cement plant in Alberta. The project aims to capture over 1Mt/yr of CO₂.
In 2023, the Minister of Innovation, Science and Industry signed a letter of intent to contribute US$191m to the project, with US$34m already allocated for phase one. The remaining US$157m will be finalised through a phase two agreement to support the construction of the CCUS system and a combined heat and power (CHP) facility. The funding has been earmarked under the Strategic Innovation Fund (SIF) and is contingent on Heidelberg Materials making its final investment decision.
“This groundbreaking partnership with Heidelberg Materials takes us one step closer to a net-zero Canada by 2050,” Minister of Innovation, Science and Industry François-Philippe Champagne said. “By building North America’s first carbon capture system in cement, we’re driving innovation, cutting emissions and securing a sustainable future.”
National Cement and Carbon TerraVault partner for California’s first net-zero cement plant
04 March 2025US: California Resources Corporation and its carbon management subsidiary, Carbon TerraVault (CTV), have signed a memorandum of understanding (MoU) with National Cement Company of California to develop the ‘Lebec Net Zero’ project, which will produce carbon-neutral cement at National Cement’s Lebec facility in Kern County, California.
CTV will provide transportation and sequestration solutions for up to 1Mt/yr of CO₂ emissions captured from the Lebec plant. The captured CO₂ will be transported and stored in CTV’s underground storage reservoirs. The project will integrate carbon capture technology, use locally sourced biomass fuel from agricultural byproducts and produce limestone calcined clay cement (LC3).
Pending customary approvals, operations are expected to commence in 2031.
Global Cement and Concrete Association launches Innovandi Open Challenge 2025 for low-carbon concrete
21 February 2025Global: Global Cement and Concrete Association (GCCA) has launched the Innovandi Open Challenge 2025, inviting start-ups to wok together with cement manufacturers around the world in developing low carbon concrete technologies.
The Open Challenge is looking for start-ups working on next generation materials for net zero concrete, including low-carbon admixtures, supplementary cementitious materials, activators or binders. The challenge aims to find ways to reduce clinker use and incorporate new materials to lower CO₂ emissions.
The programme follows three previous Open Challenges.
Chief executive Thomas Guillot said "Advanced production methods which are decarbonising our sector are already being used in cement and concrete production in many parts of the world. Through the Innovandi Open Challenge, start-ups can bring in even newer ideas and further accelerate our industry's push."
“If you are a start-up from anywhere in the world with an innovative idea or technology, then we want to hear from you."
Start-ups can find more information and apply to take part in the Innovandi Open Challenge by going to the GCCA Open Challenge 4 webpage: Innovandi Open Challenge 4 : GCCA
Belgium: Gebr. Pfeiffer has received an order for an MVR 5000 R-4 vertical roller mill. The mill is intended for a new 4800t/day line at Holcim Belgique's Obourg cement plant, the site of the GO4ZERO decarbonisation project.
The mill will grind 370t/hr of cement raw material to a fineness of ≤15%R to 0.090mm and reduce moisture content from 4% to <0.7%. The mill is expected to reduce both emissions and specific operating costs.
Chinese contractor CBMI is managing the installation, with commissioning planned for the second half of 2025. The mill will be integrated into the plant's oxyfuel operations to achieve efficiency in the CO2 capture process.
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.”
