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.”

US: 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: 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.

US: 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.”

Europe: Sweden-based SaltX has signed a letter of intent with German engineering firm thyssenkrupp Polysius to collaborate on establishing 100% electric cement production facilities in Europe. The facilities will combine SaltX’s electric arc calciner (EAC) technology with thyssenkrupp Polysius’ material handling solutions.

CEO of SaltX Lina Jorheden said "Strong partnerships are essential for us to effectively implement our technology and reduce millions of tonnes of CO₂ emissions from the industrial sector. Our collaboration with thyssenkrupp Polysius is crucial for developing complementary systems to the EAC technology and building electrified facilities for our customers."

Sweden: Heidelberg Materials has successfully operated a 300kW plasma-heated cement kiln at its Slite cement plant, which it claims is the first of its kind. The producer has achieved 54 hours of continuous operation, with 60% CO₂ concentration in the flue gas. The aim is to reach 99%.

The kiln is part of the ELECTRA project, which aims to replace traditional combustion processes with electricity-based solutions, like plasma. The project consists of 17 partners from 8 countries.

Project manager Bodil Wilhelmsson said "It looks very promising. We started the tests at the end of last year and can now say with certainty that this is the right way to go: we will be able to produce clinker with plasma."

Fuel-related CO₂ emissions from cement production are eliminated because no fuel needs to be used in the production process. Instead, CO₂ is heated to over 5000°C, where it becomes a plasma jet that heats the material in the kiln.

Wilhelmsson added "The absence of fuel in the process means that there is no ash in the product. This means that a parameter that could affect the quality of the product if it fluctuates is no longer considered. So, it looks like the quality of the clinker can actually be slightly higher in this process."

Heidelberg Materials plans to build a 1MW kiln in Skövde cement plant in 2026, where further tests will continue.

Spain: Molins and Enagás have formalised an agreement to promote their Mosusol netCO₂ carbon capture and storage (CCS) project for EU Innovation Fund backing. The project will capture 1Mt/yr of CO₂ at Molins’ cement plant in Sant Vicenç dels Horts, near Barcelona, to be transported by Enagás for storage. The project will cost an estimated €590m.

Molins CEO Marcos Cela said "The Mosusol netCO₂ Project is an example of our firm commitment to the decarbonisation of the construction sector. Our goal is to achieve carbon neutrality at our Sant Vicenç dels Horts plant by 2031."

Egypt: Arabian Cement Company (ACC) has signed a €25m loan agreement with the European Bank for Reconstruction and Development (EBRD). The loan will be used to assist the company’s decarbonisation efforts. It will finance the company’s alternative fuel capacity expansion and automation of its facilities. The company will also acquire and install a hydrogen injection system at its Ain Sokhna cement plant. This will reduce CO₂ emissions by 130,000t/yr.

CEO of Arabian Cement, Sergio Alcantarilla, said "This agreement with EBRD is a key milestone in ACC's sustainability journey, supporting our transition to cleaner technologies. The integration of the hydrogen injection at our Ain Sokhna plant will enhance operational efficiency and significantly reduce our carbon footprint."
