US: 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.”

Greece: Heracles, part of the Holcim Group, has signed a front-end engineering design contract (FEED) with Air Liquide for CO₂ capture, liquefaction, storage and dispatch facilities at the Heracles plant in Milaki, as part of the Olympus carbon capture and storage (CCS) project. The project will enable the plant to capture and store 1Mt/yr of CO₂ and is scheduled for full operation in 2029. The captured CO₂ will be liquefied and transported by sea to the offshore sequestration facility in Prinos in the northern part of the Aegean Sea.

Germany: KHD will carry out a front-end engineering design (FEED) study for the new oxyfuel kiln at Heidelberg Materials' Geseke cement plant, part of the GeZero carbon capture and storage (CCS) project. The project will capture and store around 0.7Mt/yr of CO₂.

Matthias Mersmann, chief technology officer at KHD, said "At KHD, we have long recognised oxyfuel technology’s potential for cement decarbonisation and are well-positioned to contribute to this important flagship project.”

Germany: Capsol Technologies has signed a cooperation agreement with Holcim to deliver a CapsolGo carbon capture demonstration campaign at Holcim’s Dotternhausen plant in southern Germany. The CapsolGo campaign will test Capsol’s carbon capture technology using its hot potassium carbonate (HPC) solvent. Capsol Technologies will provide the demonstration as a turnkey solution, including testing and validation to supply critical data and insight into the technology.

Dieter Schillo, plant manager of Holcim (Süddeutschland), said “The CapsolEoP (End-of-Pipe) unit’s design, requiring no external steam supply and exhibiting low energy consumption, makes it an attractive option for our Dotternhausen plant.”

If successful, Holcim plans to deploy Capsol’s technology across multiple cement plants globally. This builds on a feasibility study conducted by Aggregate Industries UK, a Holcim subsidiary, for the Cauldon cement plant in Stoke-on-Trent. Testing at Dotternhausen will run for four months, starting in the second quarter of 2025.

US: 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.

France: Lafarge France, part of Holcim, will deploy the technology of the Swiss start-up Neustark on its Gennevilliers site. This means that around 1000t/yr of CO2 could be sequestered into recycled concrete.

Neustark’s principle consists of injecting the liquefied CO2 into recycled gravel. The gas then reacts with the calcium present and forms calcium carbonate crystals. It is thus transformed and can be stored indefinitely. Neustark has already deployed its technology at 22 sites in Europe, mainly in Switzerland and Germany.

The Gennevilliers plant already receives demolition concrete and transforms it into recycled aggregates used in ready-mix concrete gravel and road sub-bases. The site, which produces 80,000t/yr of recycled materials, will be able to transform around 1000t/yr of CO2, as Neustark's technology can store 10kg of CO2 per tonne of recycled demolished concrete.

Denmark: INEOS has announced the final investment decision to permanently store CO₂ from Danish emitters in the Nini oil field in the Danish North Sea. The company aims to begin operations by late 2025 or early 2026, creating the ‘EU’s first operational CO₂ storage facility intended to mitigate climate change.’

The project, Greensand Future, will start by storing 400,000t/yr of CO₂, with a potential to scale up to 8Mt/yr by 2030. CO₂ will be captured from Danish biomethane plants, liquified, transported to Esbjerg port and shipped to the Nini oil field for permanent storage. Investments will exceed US$150m to scale storage capacity.

Mads Gade, head of INEOS Energy Denmark, said “Last year we were the first in the world to succeed in developing a value chain for safe and efficient capture, transport and storage of CO₂ across national borders. Now we are proud to take the next step, building on the learnings from the pilot and aiming to deliver a fully operational commercial project by the end of 2025/early 2026.”

UK: Nuada and Carbfix have signed a memorandum of understanding to deliver integrated carbon capture and storage (CCS) solutions targeting emissions reduction in the cement, lime, steel, waste-to-energy and bioenergy sectors. The partnership combines Nuada’s carbon capture technology with Carbfix’s underground CO₂ mineralisation method.

Nuada’s technology uses solid sorbents, metal organic frameworks, and vacuum pressure swing adsorption to capture CO₂ from the source while addressing barriers like energy consumption and cost. Carbfix’s storage method accelerates the mineralisation process by injecting CO₂ into basaltic rock, where it reportedly transforms permanently into stone within two years.

Germany: Fluor has signed a front-end engineering and design (FEED) contract with Heidelberg Materials for its GeZero project to integrate an industrial-scale CO₂ capture and storage solution into its cement production facility in Geseke. Fluor will recognise the undisclosed contract value in the fourth quarter of 2024. It will be responsible for design integration of several decarbonisation technologies at the Geseke cement production facility. Construction is planned to start in 2026, with commissioning three years later.

Norway: SLB Capturi has reached mechanical completion of the carbon capture unit at Heidelberg Materials' cement plant in Brevik. The unit includes the carbon capture system, compression system, heat integration system, intermediate storage, and loadout facilities. The plant is now ready for testing and commissioning. The carbon capture plant is designed to capture up to 0.4Mt/yr of CO₂ from one production line at the cement plant. When operational, this world-first commercial-scale carbon capture plant at a cement plant will enable production of an amount of net-zero cement, without compromising on the product strength or quality. SLB Capturi is a joint venture between SLB and Aker Carbon Capture.

"Reaching this milestone is a testament to the power of working together and the collective determination to make a positive climate impact," said Egil Fagerland, CEO of SLB Capturi. "We look forward to continuing these collaborative efforts as we move toward the commissioning and operational phases of the project. The Brevik CCS plant sets a precedent for future carbon capture initiatives, where learnings and insights from this groundbreaking project enable others to follow."

"The mechanical completion of the Brevik CCS project is a landmark achievement in the decarbonisation journey of the cement industry,” said Giv Brantenberg, general manager Northern Europe, Heidelberg Materials. “This project exemplifies our commitment to innovation, collaboration, and the pursuit of solutions that address the pressing issue of climate change. We are immensely proud of the dedication and hard work of our teams and partners who have made this possible."
