Lithuania: Capsol Technologies has commenced its first CapsolGo demonstration campaign at the Akmenės Cementas plant in Lithuania, owned by Schwenk, to evaluate its carbon capture technology.

Schwenk plans to test Capsol’s technology at two cement plants, with a combined CO₂ capture potential of 1.5Mt/yr. Following the demonstration campaign at the Akmenės plant in Lithuania, the CapsolGo unit will be transferred to Schwenk’s Brocēni cement plant in Latvia, where a feasibility study was conducted in 2024.

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.

Japan: Fortera is collaborating with Sumitomo Corporation to introduce its ReCarb technology in Asia, starting with Japan. The two companies have signed a memorandum of understanding to deploy Fortera’s bolt-on ‘low-to-zero-carbon’ cement plants across the region, focusing on the largest cement manufacturers.

Fortera’s ReCarb process converts industrial CO₂ directly from cement production into cement that is reportedly third-party verified as having 70% less embodied carbon tonne-for-tonne than ordinary Portland cement. When paired with renewable energy, Fortera can achieve zero-CO₂ cement production.

Ryan Gilliam, CEO of Fortera, said "This partnership is a pivotal moment for the future of sustainable cement production, because you can’t make a meaningful impact on the industry’s carbon emissions without partnering with major industry players in Asia, which is home to the largest cement market in the world."

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.
