UK: C-Capture has initiated a carbon capture trial at Heidelberg Materials’ Ketton cement works in Rutland, as part of its national 'XLR8 CCS' project aimed at accelerating low-cost carbon capture solutions in industries like cement and glass. The trial utilises C-Capture’s technology, which employs a solvent to selectively capture CO₂ from emissions. According to the company, this process does not rely on the use of amines, therefore requiring 40% less energy than conventional methods and reduces costs. The carbon capture solvent compatibility unit designed by C-Capture and partner Wood will test the effectiveness of this technology in removing CO₂ from flue gas emissions produced during the cement manufacturing process.

XLR8 CCS is funded with €2m from the Department of Energy Security and Net Zero’s €1.2bn Net Zero Innovation Portfolio. The funding is part of the €23m Carbon Capture, Usage and Storage (CCUS) Innovation 2.0 programme aimed at accelerating the deployment of next-generation CCUS technology in the UK. Additional private sector contributions support a €3.1m total.

C-Capture CEO Tom White said "Decarbonising industry is one of the most pressing global issues. C-Capture’s XLR8 CCS project is a critical step in the race to net zero as we work with our innovative technology and leading industry partners to demonstrate that an affordable carbon capture solution is a reality – even for industries that are difficult to decarbonise. We are incredibly proud to be working with our project partners which have strong commitments to decarbonisation and are early adopters of novel carbon capture technology."

Simon Willis, CEO of Heidelberg Materials UK said “Carbon capture is a critical part of our strategy to decarbonise cement production and essential if we are to reach net zero and help our customers achieve their own decarbonisation goals. Our venture with C-Capture is another example of our commitment to developing new technologies and, if successful, has the potential to be rolled out at other sites across the Heidelberg Materials Group.”

Germany: Buzzi subsidiary Deuna Zement plans to invest €350m to install a carbon capture system at its cement plant in Deuna, having completed two feasibility studies. The Thüringer Allgemeine newspaper has reported that, when operational in 2029, the system will capture 620,000t/yr of CO₂. This will make the Deuna cement plant carbon neutral. The company has applied for government funding for the project.

Buzzi Unicem said that its subsidiary is ‘Doing pioneering work on the path to decarbonising the cement industry.’ It added “The system will be efficient and take all relevant environmental considerations into account.”

Spain: The Spanish cement manufacturers' association, Oficemen, and Siemens Energy have signed a two-year collaboration agreement to develop decarbonisation techniques and solutions for Spain's cement industry. The agreement was signed by Siemens Energy's Industrial Sales Director for Southwest Europe, Angel Cillerruelo, and Oficemen's General Director, Aniceto Zaragoza.

Zaragoza said "The Spanish cement industry's commitment to climate neutrality by 2050, outlined in our roadmap, includes exploring the most effective levers for emission reduction, such as the decarbonisation of energy sources or the comprehensive energy management of industrial processes."

Global: The Global Cement and Concrete Association (GCCA) has announced new collaborations between global cement manufacturers and technology start-ups, focusing on the development of low carbon concrete. Four start-ups—EnviCore in Canada, Queens Carbon and Chement, both in the US and NeoCrete in New Zealand—were part of the 2023 GCCA Innovandi Open Challenge and have now partnered with cement manufacturers. These partnerships aim to reduce the carbon footprint of concrete.

The startups will receive access to industry plants, labs and networks to fast-track their technologies. They will also demonstrate their progress on 6th June 2024 in Bangkok, Thailand, during the GCCA's CEO and Leaders Conference. The association continues its efforts under the 2050 Net Zero Concrete Roadmap, with 29 new start-ups shortlisted this year to work on carbon capture, utilisation and storage (CCUS) technology.

UK: Seratech has developed a process using olivine, a mineral abundant in Earth's mantle, to produce ‘carbon-negative’ cement. The company's method involves replacing some of the clinker with silica extracted from olivine. Magnesium sulphate derived from the olivine reacts with CO₂ to form nesquehonite, a mineral that sequesters CO₂. This method uses CO₂ captured from emissions sources or directly from the air.

Sam Draper, CEO, explained the process: “The researchers extracted these compounds by dissolving powdered olivine in sulphuric acid. After separating the silica and magnesium sulphate, they bubbled CO₂ through the magnesium slurry to form nesquehonite.”

According to Draper, replacing 35% of regular cement with this silica would yield carbon-neutral results, while a 40% substitution could achieve carbon negativity. Current building standards allow up to 55% of cement to be replaced by this material, although robust testing has yet to be conducted.

Malaysia: Heidelberg Materials has announced its acquisition of ACE Group, a supplier of pulverised fly ash, effective 1 May 2024. Reusing fly ash from energy generation contributes to reducing the CO₂ intensity of composite cement. When used as an additive, fly ash can replace part of the energy-intensive clinker and thus reduce the CO₂ intensity of the cement.

The acquisition includes ACE Greencemt Venture, ASAS Asia and AGP Logistics, with the leadership team from ACE Group continuing to manage the operations post-acquisition. Both parties have agreed not to disclose the financial terms of the transaction.

Germany: Holcim Deutschland has broken ground on the construction of a new kiln line and CO₂ processing unit at its Lägerdorf cement plant in Schleswig-Holstein. The line will feature an OxyFuel kiln, supplied by ThyssenKrupp. ThyssenKrupp’s OxyFuel technology will assist in the capture of 1.2Mt/yr (nearly 100%) of CO₂ from the plant. The partners described the upcoming upgraded Lägerdorf plant as one of the world's first carbon-neutral cement plants.

Holcim Deutschland CEO Thorsten Hahn said "We're laying the groundwork for a sustainable world through cement. Cement is essential for our cities, factories, homes, bridges and beyond. As we transition towards renewable energy, we must also construct the foundations and structures for wind turbines and railway tracks. With our climate-neutral cement plant, we ensure that this vital building material remains accessible without further harm to the atmosphere."

ThyssenKrupp Decarbon Technologies’ chief strategy officer Cetin Nazikkol said “It’s vital to switch to climate-friendly processes. By enriching CO₂ by means of the pure OxyFuel technology we’ve developed, we help our customers capture almost all of the CO₂ arising in the production process and so reuse it in a sustainable manner. Given that global cement production is more than 4Bnt/yr, we see enormous growth potential for our innovative technology.”

Switzerland: The Global Cement and Concrete Association (GCCA) is holding its Innovandi Global Cement and Concrete Research Network (GCCRN) Spring Week at the École polytechnique fédérale de Lausanne (EPFL) campus on 22 – 26 April 2024. 450 delegates from over 40 academic institutions will attend the event, featuring workshops, idea exchanges and progress reviews focused on the decarbonisation of cement and concrete by 2050. Topics include the use of AI, alternative materials and processes, concrete recycling, renewables, kiln electrification and carbon capture.

GCCRN industrial chair and Cemex global research development vice president and Davide Zampini said “If we are to reach our goal of net zero concrete by 2050, then we cannot do so alone. We need to explore as well as harness solutions and collaboration well beyond our industry. That’s why Spring Week is so important.”

GCCRN scientific chair Karen Scrivener said “Everyone here at EPFL is proud to be hosting this year’s Spring Week, anticipated as our largest gathering yet, marking a significant milestone in our journey toward net zero research.”

Taiwan: Taiwan Transport and Storage unveiled its first electric truck, manufactured by Volvo Trucks, at a ceremony in Taipei. The unit will transport cement for Taiwan Cement, marking the first use of electric vehicles for construction material transport in Taiwan, according to the Taipei Times.

The electric truck unit will help to reduce aggregate carbon emissions by 32%, according to TTS chairman Koo Kung-yi. "We believe that Taiwanese companies can effectively reduce Category III CO₂ emissions through the use of electric commercial vehicles," Kung-yi said.

Poland: Polish cement producers are set to build carbon capture installations, supported by government policies. After a decline in production from nearly 19Mt in 2022 to about 16.5Mt in 2023, the industry is facing an increase in cheaper imports from outside the EU, particularly Ukraine, and CO₂ emission fees that account for 30% of the cost of 1t of cement, according to the Dziennik Gazeta Prawna newspaper. The EU has also introduced a carbon border adjustment mechanism (CBAM) for imports.

Despite these challenges, the Kujawy cement plant in Bielawy, owned by Holcim, is launching the large-scale implementation of carbon capture and storage (CCS) technology.

Holcim Polska's president, Maciej Sypek, said "The construction of carbon capture installations in our plants will cost between €320m and €400m. We received a €264m grant from the European Commission's Innovation Fund." According to Sypek, the project is currently in the design phase, with construction expected to start in 2025 and operations beginning in early 2028.

The implementation of CCS at the Kujawy plant could potentially lead to an industry-wide adoption of the technology, costing between US$3.7bn and US$4.9bn, according to the newspaper. Holcim Polska plans to liquefy the CO₂ and transport it by rail to a terminal in Gdańsk, where it will be shipped to the North Sea for underground storage. Cement producers are urging the Polish government to appoint a commissioner for CCS infrastructure and to enact legislative changes to support the construction of such installations. They also believe that rapid modernisation of the energy sector needs to occur to support the energy-intensive process of gas capture.
