Greece: The IFESTOS carbon capture project at Titan Group's Kamari cement plant was among eight CO₂ emissions-reducing projects chosen for funding following the latest EU Innovation Fund call for projects. IFESTOS consists of a planned 1.9Mt/yr carbon capture installation at the Kamari plant. Titan Group says that it has concluded necessary memoranda of understanding (MoUs) with suppliers. The IFESTOS project will receive a share of a funding pot worth a total Euro3.6bn.

Chair Marcel Cobuz said "We are truly excited that the European Commission has chosen to support our large-scale, highly innovative project. IFESTOS is a cornerstone of our accelerated decarbonisation roadmap to net-zero. In line with EU climate policy, together with our technology partners, we are pioneering an innovative carbon capture project, the largest in Europe, with a highly positive impact. The group has strong capabilities and is committed to executing this project fast over the next few years, decarbonising production and offering green growth opportunities to our customers in Europe. We embrace the opportunity to widely share our knowledge and expertise and promote green cements as modern materials for infrastructure and housing.”

Germany: The EU Innovation Fund has granted funding to the GeZero carbon capture project at Heidelberg Materials' Geseke cement plant in North Rhine-Westphalia. The project consists of a 700,000t/yr carbon capture system and an oxyfuel kiln upgrade. A captive solar power plant will provide energy for the new systems. CO₂ storage partner Wintershall Dea will receive purified liquefied CO₂ from the capture system via its Wilhelmshaven distribution hub for storage under the North Sea.

Heidelberg Materials Germany general manager Christian Knell said “This project sets an important milestone for the cement industry and for effective carbon management in Germany. We are now counting on the tailwind of Germany’s future Carbon Management Strategy and the regulatory framework to come.”

CEO Dominik von Achten added “With GeZero, we will once again show how Heidelberg Materials’ pioneering spirit is paving the way for the decarbonisation of our industry. We will be the first to realise a full CCS chain for the capture, transport and permanent storage of all CO₂ emissions from an inland location in Germany. I appreciate the support of the EU Innovation Fund, which expresses both an important recognition and the required backing from the political side.”

Norway: Capsol Technologies has been awarded a feasibility study for the CapsolEoP (end-of-pipe) carbon capture product at an unnamed cement plant in Northern Europe. The study is for a plant aiming to capture more than 1Mt/yr of CO₂. The award is Capsol Technologies’ first paid engineering study on a cement plant. The company says it is seeing an increasing amount of request and sales engineering work in the cement sector and it expects more engineering studies to be awarded going forward.

Jan Kielland, the chief executive officer of Capsol Technologies, said “The fact that the CapsolEoP carbon capture technology is easy to integrate without disrupting the operations of the host plant is an attractive value proposition to these types of facilities. In addition, the emission from a cement plant has a high concentration of CO₂ making it especially beneficial for the CapsolEoP technology relative to competing technologies, bringing down the cost per unit CO₂ captured.”

Norway-based Capsol Technologies is promoting a solvent/scrubbing-based approach to carbon capture using hot potassium carbonate (HPC). It was awarded a technology licensing agreement for the Stockholm Exergi BEECS (Bioenergy Carbon Capture and Storage) project in July 2022. It has also received orders for its CapsolGo carbon capture demonstration unit in Sweden and Germany.

France: Heidelberg Materials, Lafarge France, Lhoist and utilities provider TotalEnergies launched the GO CO₂ carbon capture and storage project at the port of Nantes-Saint-Nazaire on 10 July 2023. The Le Marin newspaper has reported that the Euro1.7bn project will treat and liquefy captured CO₂ for underwater storage. The initial participating plants will be Lafarge France’s Saint-Pierre-la-Cour cement plant and Lhoist’s Neau lime plant.

Preliminary studies will commence later in 2023, with an investment decision to be taken in 2027, for commissioning of the project in 2030. The consortium will initially process 2.6Mt/yr of captured CO₂, rising to 4Mt/yr in 2050.

US: In 2022, Fortera began building a 15,000t/yr-capacity plant to produce its low-carbon cementitious material, Fortera Reactive Calcium Carbonate (RCC), at CalPortland's Redding cement plant in California. The commercial-scale plant will produce a reactive form of calcium carbonate using CO₂ from the kiln of the 600,000t/yr cement plant. Fortera's process converts 1t of limestone into 1t of Fortera RCC by capturing and mineralising CO₂ from the cement plant's kiln. Fortera cement production emits 60% less CO₂ than ordinary Portland cement (OPC). The 15,000t/yr plant will operate at 20 times the scale of previous pilot tests. The Redding Record newspaper has reported that 15 workers will be employed at the site.

Former Redding cement plant owner Lehigh Hanson formed an agreement with Fortera to collaborate on the low-carbon cement plant project in March 2021. The plant subsequently switched ownership to Martin Marietta Materials in October 2021, before CalPortland bought it in July 2022.

China: Asia Cement has launched its 2050 decarbonisation strategy, entitled 'Net-Zero Carbon Emissions By 2050 - Asia Cement Advanced Deployment.' The strategy consists of multiple pillars, namely 'alternative fuels,' 'reducing cement's clinker factor,' 'increasing renewable energy reliance' and 'carbon capture.'

During 2022, Asia Cement reduced its limestone, clay, iron and sand consumption by 266,000t, its coal consumption by 17,000t and its gypsum consumption by 56,000t year-on-year. This eliminated 95,100t of CO₂ emissions throughout the year, according to the producer.

Spain: Cementos Tudela Veguín plans to spend more than Euro62.5m on sustainability-enhancing upgrades to its three cement plants in Asturias and one in León. The plans consist of upgrades to fuelling systems that will enable the plants to use biofuels and hydrogen, as well as efficiency upgrades. The La Nueva España newspaper has reported that the producer is seeking to secure European Union (EU) funding for the project. The region of Asturias is eligible for Euro263m-worth of regional decarbonisation funding under the EU's Strategic Project for Economic Recovery and Transformation.

A planned second phase of upgrades will consist of the installation of carbon capture systems at the plants. They emitted 1.67Mt CO₂ in 2022. 1.12Mt (67%) arose from the decarbonisation of limestone and 0.55Mt (33%) came from the combustion of fuel.

Cemex highlighted its Clyngas project at its Alicante cement plant in Spain this week. The project will produce synthesis gas (syngas) from different types of waste for direct injection into the burner at the plant during the combustion process. It is being run in conjunction with Waste to Energy Advanced Solutions (WTEnergy), a company that Cemex invested in at the end of 2022. It is also receiving Euro4.4m in funding from the European Commission (EC) as part of its innovation fund for small scale projects. The initiative estimates that it will save over 400,000t of equivalent CO₂ during the first 10 years of the project's life by replacing petroleum coke with syngas.

Clyngas is another example of Cemex’s innovation with alternative fuels for cement and lime. It follows on from the group’s work with hydrogen injection into cement kilns. As presented at the 15th Global CemFuels Conference 2022 it has been using hydrogen in low volumes as a combustion enhancer in more than 20 plants worldwide. However, it was also looking into using hydrogen more directly as a fuel and as a feedstock for other alternative fuels. WTEnergy’s gasification process could potentially link up to this as it converts waste streams such as wood chips, agricultural waste, refuse derived fuel (RDF), solid recovered fuel (SRF), dry sewage sludge, meat and bone meal, poultry litter and plastics into syngas. WTEnergy then proposes that its gasification process and/or the syngas can be used for power generation and thermal applications. In the case of the Clyngas project it will be the latter, as the gasification process will be used to boost the burnability characteristics of RDF with a high biomass content. One part of this to note is that the syngas can potentially be used to manufacture hydrogen. This would be a useful capability for a cement company, for example, that was already using alternative fuels and was now considering further decarbonisation by switching to using hydrogen.

A few other cement companies have been looking at synthetic fuels too, but this has generally been as a by-product of carbon capture and utilisation. This week Lafarge France, for example, said it had signed a memorandum of understanding with Axens, EDF and IFP Energies Nouvelles for a synthetic fuel production trial. Its plan is to build a unit that will produce synthetic kerosene using captured CO₂ from a carbon capture installation at Lafarge France's Saint-Pierre-La-Cour cement plant. The kerosene will then be sold to airlines. Other examples of cement companies looking at using captured CO₂ to manufacture synthetic fuels include Finnsementti’s pre-engineering study with Aker Carbon Capture to consider producing methanol as a fuel for transport, Holcim’s and TotalEnergies’ various plans of what to do with the CO₂ captured from the-to-be upgraded Obourg cement plant and Cemex Deutschland’s ambitions for its Rüdersdorf plant.

As can be seen above there are different types of synthetic fuels and cement companies are at the research and pilot stages. Although there isn’t a commonly accepted definition of what a synthetic fuel is, the general meaning is that of a fuel made from feedstock using a chemical reaction as opposed to, say, a refining process. The wide variety of potential synthetic fuels puts the confusion over the different types of hydrogen into perspective. However, this may be a problem for a later date if usage by cement companies becomes more serious.

What is a problem, though, has been the EC’s planned legislation to phase out the use of industrial CO₂ in synthetic fuels by 2041. Cembureau, the European cement industry association, warned in late 2022 of the issues this would pose for industries trying to find a way to utilise their CO₂ emissions where storage was too difficult or expensive. Its view was that while synthetic fuels using industrial CO₂ are not fully net-zero, as the captured CO₂ is later released into the atmosphere, it is a necessary short to medium term step for sectors trying to make the transition. Companies trying to build industrial-scale chemical plants for synthetic fuels need running periods of 20 to 30 years to achieve payback. As of March 2023 Cembureau was still concerned about the implication of proposed regulations, specifically with regards to the proposed criteria for which synthetic fuels could be used, based on their greenhouse gas emissions savings (at least 70% compared to the regular fuels being replaced). It directly linked this to synthetic fuels projects being launched by the cement sector that might be adversely affected by the new rules. The EC published the legislation in late June 2023 and it is set to become legal in mid-July 2023.

Using synthetic fuels either as a fuel or a by-product from cement production is an area of interest currently with the projects detailed above and others in progress. One vision for their use in Europe, at least, is that they might offer a route for carbon capture for cement plants without access to the logistic networks necessary for sequestration. Whether they find a place in cement manufacture either on a transitional basis or over a longer term should become clearer over the coming decade. Yet the EC’s new rules are likely to slow this process down as at least some of the planned pilots may become unviable in Europe. Other jurisdictions around the world take note.

Canada: Heidelberg Materials North America has appointed engineering firm WSP to carry out design, engineering and implementation of a planned 1Mt/yr carbon capture installation at its Edmonton cement plant in Alberta. Construction will begin in late 2024 and reach completion in late 2027. Through the project, Heidelberg Materials North America aims to realise net zero CO₂ cement production at the 1.4Mt/yr Edmonton plant.

Heidelberg Materials’ vice president of cement Joerg Nixdorf said "WSP’s proven track record of delivering high-quality and sustainable engineering solutions aligns perfectly with our vision of driving decarbonisation in the cement industry. Together, we will push the boundaries of what's possible and create a truly transformative project."

France: Vicat says that it will commission its planned 100% carbon capture system at its Montalieu-Vercieu cement plant ‘before 2030,’ and possibly as soon as 2027. The Les Echos newspaper has reported that the system will have a capture capacity of 1Mt/yr of CO₂, although the plant’s emissions are currently 800,000t/yr. Captured CO₂ may then be transported by barge, train or pipeline to the port of Fos-sur-Mer.

When commissioned, the upcoming carbon capture system will reduce the CO₂ emissions of cement produced at the Montalieu-Vercieu plant by 94% to 40kg/t.
