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.”

Global: The World Cement Association has released a white paper titled ‘Long-Term Forecast for Cement and Clinker Demand’, authored by CEO Ian Riley. The paper predicts a global decline in cement demand to 3Bnt/yr by 2050, with clinker demand dropping to 1.5Bnt/yr.

The report attributes the decline to decarbonisation, technological advancements and market dynamics, with the need for carbon capture and storage consequently reduced.

Ian Riley said “The cement industry is undergoing an unprecedented transformation. As we move towards a decarbonised future, understanding the true demand for cement and clinker is critical to ensuring that policies, technologies and investments align with reality. This white paper aims to provide industry leaders and policymakers with the clarity needed to plan effectively and sustainably.”

The analysis also explores disruptive factors such as alternative materials, supply chain optimisation and clinker-free technologies, presenting three scenarios to guide stakeholders in adapting to industry changes and fostering innovation.

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.

Suvo Strategic Minerals said this week that it had made moves towards establishing a joint-venture between a subsidiary and the Huadi Bantaeng Industry Park (HBIP). The plan is to manufacture and sell low-carbon cement and concrete products that contain nickel slag and other byproducts. This news story is noteworthy because of the location of HBIP in South Sulawesi, Indonesia.

In a release to the Australian Securities Exchange Suvo explained that HBIP is the managing company of the Bantaeng Industrial Park, where ‘significant’ quantities of nickel slag are stockpiled as part of the local nickel pig iron operations. HBIP will supply the nickel slag to the joint-venture. It will also give it access to infrastructure such as land, port facilities and utilities. Suvo subsidiary Climate Tech Cement, for its part, will supply the low carbon cement and or concrete mixtures and/or formulations. This follows the signing of a memorandum of understanding in September 2024, in which the companies agreed to process the nickel slag into geopolymer cement and precast concrete materials.

At first glance Indonesia seems like an unlikely place to market a low-carbon cement or concrete product, given the large cement production overcapacity in the country. The Indonesian Cement Association (ASI) reported a production capacity of just under 120Mt/yr in 2024 and forecast a utilisation rate of 57% in November 2024. However, the government seems serious about reaching net zero by 2060 as the country’s economy develops. The ASI updated its decarbonisation roadmap in 2024 and the draft is currently under review with the Ministry of Industry and consultants from the Bandung Institute of Technology (ITB).

In the latest roadmap, carbon capture is at least a decade away, with the first large-scale capture tentatively anticipated from 2035 onwards. Although Indonesia launched its carbon trading scheme in 2023, it is not expected to start affecting the industrial sector until the late 2020s. Instead, the short-to-medium term Scope 1 reduction methods include increasing the use of alternative fuels, reducing the clinker factor of cement and reducing and/or optimising the specific thermal energy consumption of clinker. Initiatives such as Suvo’s joint-venture in South Sulawesi tie into that middle strand. Separately, over the summer of 2024 the government and producers said that they were working together to introduce and promote the use of Portland composite cement (PCC) and Portland pozzolana cement (PPC). At this time the ASI reckoned that a complete change could cut cement sector emissions by just over a quarter. In June 2024 local media also reported that ASI members were planning to supply low-carbon cement for the Nusantara capital city project to help it realise its aims as a ‘green city.’

Semen Indonesia, the country’s largest producer, reported a clinker factor of 69% in 2023 for all of its cement products, down from 71% in 2021. Limestone was the biggest substitute followed by trass and gypsum. It is currently aiming for a clinker factor of 61% by 2030. In its Sustainability Report for 2023 it said that it was promoting the use of non-OPC (Ordinary Portland Cement) cement “...according to the needs of construction applications.” It added that non-OPC products also had a “...5 - 15% more economical price.” However, the company has not said how its current sales are split between OPC and other products.

One of the surprises at the 26th Technical Symposium & Exhibition of the ASEAN Federation of Cement Manufacturers (AFCM), that took place in Kuala Lumpur in November 2024, was the sheer amount of work that has been going on outside of Europe and North America towards decarbonising building materials. The cement associations of Indonesia, Malaysia and Thailand all presented progress and targets towards this aim at the event. Suvo Strategic Minerals’ joint-venture plans in South Sulawesi are another example of this trend.

Closing points to note about the Suvo project are firstly that it is away from Indonesia’s main cement production area in Java. Secondly, the presumption is that the low-carbon cement and concrete products manufactured by the project will either be cheaper than the competition or benefit from green procurement rules. Finally, nickel slag reserves seem insufficient to reshape the entire national cement market. Yet a general move towards using more supplementary cementitious materials could. Watch this space for more developments.

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.”

Portugal: Cimpor plans to invest €1.4bn in its Portuguese cement assets by 2030, focusing on infrastructure, technology and new products to address decarbonisation, described as the ‘number one challenge’ by CEO Cevat Mert, according to Noticias Financieras news.

In October 2024, Cimpor announced an investment of €360m in decarbonisation and innovation projects by 2026, including €180m allocated to its Alhandra plant in Lisbon. The company also aims to expand into more markets beyond the 14 it currently serves. It has invested €20-25m in a terminal at the port of Bristol in the UK, and has plans for France and the US. Ignacio Gomez, Cimpor’s commercial manager, cited this shift towards Europe and the US due to stricter environmental requirements.

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.

Belgium: Holcim has selected the joint venture between BESIX and DENYS as the main contractor for the civil works of the upgrade at its Obour, Mons, plant. The GO4ZERO project will produce nearly 2.3Mt/yr of carbon-neutral cementitious materials by 2029. In a separate contract, BESIX’s subsidiary Franki Foundations is handling the deep foundations. Work began in August 2024 and will conclude in February 2025.

Azerbaijan: Cemex has won the Net-Zero Industries Award for its clinker decarbonisation process using concentrated solar power. The award was presented at COP29 in Baku. Cemex’s solar clinker project is a collaboration with cleantech company Synhelion, which developed the high-temperature solar heat technology it uses. Cemex and Synhelion partnered in 2019 and achieved the first successful production of solar clinker in 2022.

Davide Zampini, vice president of Global R&D at Cemex, said "Together with Synhelion, we are pioneering solar-powered clinker production, a breakthrough process that can contribute to decarbonising cement manufacturing."
