Germany: Holcim Deutschland announced a planned upgrade to its Lägerdorf cement plant’s kiln on 14 July 2022. The producer will install a second generation oxyfuel kiln, which uses an air separation unit to supply oxygen directly, emitting CO₂-rich flue gas. A new carbon capture system will supply captured CO₂ to a synthetic hydrocarbons plant, which will produce methanol for other industrial applications. The upgrade will result in the capture of 1.2Mt/yr
of CO₂ emissions and make Lägerdorf one of the world’s first carbon neutral cement plants, according to Holcim Deutschland.

The project, called Carbon2Business, was among four cement plant projects and 13 other EU-wide projects to win a share of a US$1.81bn EU Innovation Fund funding pot. CEO Thorsten Hahn acknowledged that the awarding of funds was ‘good news for Holcim and all partners working with us to decarbonise cement.’ He said “Climate change means cement change.”

Bulgaria/Poland: The EU Innovation Fund has awarded funding to Devnya Cement’s ANRAV carbon capture, utilisation and storage (CCUS) project in Bulgaria and Lafarge Polska’s Go4ECOPlanet CCUS project in Poland.

ANRAV is a full-chain CCUS project connecting Devnya Cement’s Devnya cement plant in Varna Province over 30km to the Black Sea for storage. Go4ECOPlanet applies a similar model to the capture and storage of CO₂ from Lafarge Polska’s Kujawy cement plant offshore in the North Sea. The Kujawy cement plant is situated 200km inland in Kuyavian-Pomeranian Voivodeship. The plan is part of Lafarge Polska’s strategy to realise carbon neutrality at the Kujawy cement plant by 2027.

Regarding the ANRAV project, Mihail Polendakov, Bulgaria, Greece and Albania managing director at Devnya Cement’s parent company HeidelbergCement said “Our vision in the ANRAV consortium is to realise an economically viable CCUS cluster for Bulgaria and the neighbouring regions.” He continued “Subject to regulatory and permissions aspects, it could start operation as early as 2028, with a capture capacity of 800,000t/yr of CO₂.

US: A team from the University of Colorado Boulder (UCB) has developed a carbon-neutral alternative cement from biogenic limestone. The limestone comes from farmed cocolitophores, which capture CO₂ as they grow.

The UCB scientists collaborated with colleagues from the University of Carolina at Wilmington and the National Renewable Energy Laboratory on the project. Their work has received US$3.2m in US Department of Energy funding.

UK: Karbonite UK has developed a new supplementary cementitious material consisting of mineral feedstock, geopolymers and waste biomass. The process also involves CO₂ sequestration and liquid-infused CO₂ absorption within the mineral structure. The material, called Karbonite, is activated at 750 – 850°C, releasing water, which is captured for recycling. Its CO2 emissions are 2.7kg/t, according to Karbonite UK. The developer says that Karbonite ground with 50% clinker yields a cement of equal compressive strength to ordinary Portland cement (OPC).

Karbonite UK is currently preparing a final report on the product for a major cement producer.

Managing director Rajeev Sood said “Karbonite offers a wealth of potential to an industry targeting net zero. We are excited to talk to cement and concrete producers about how they could integrate Karbonite technology into their existing process.”

UK: The UK Department for Business, Energy and Industrial Strategy (BEIS) has granted Carbon Clean Euro701,000 under its Carbon Capture, Utilisation and Storage (CCUS) Innovation 2.0 programme. Carbon Clean says that it will partner with energy engineering company Doosan Babcock and Newcastle University to develop carbon capture systems which apply non-aqueous solvent (NAS) and rotating packed bed (RPB) technology together for the first time. The partners seek to overcome the challenges of scale and cost in order to advance the widespread deployment of CCUS systems.

The CCUS Innovation 2.0 programme is part of the UK government’s Euro1.17bn Net Zero Innovation Portfolio scheme.

Germany: ThyssenKrupp Industrial Solutions’ Polysius division says that it has been commissioned by Buzzi Unicem, HeidelbergCement, Schwenk Zement and Vicat to build a pure oxyfuel kiln system at the Mergelstetten cement plant as part of the Cement Innovation for Climate (CI4C) project. No dates of the start of construction or final project commissioning of the industrial trial have been disclosed. CI4C was originally formed in 2019.

The Polysius pure oxyfuel process is a new type of clinker production process in which the otherwise normal ambient air is replaced by pure oxygen in the kiln combustion process. One advantage of the technology is that atmospheric nitrogen is eliminated from the clinker burning process leading to much higher concentrations of CO₂ in the exhaust gas compared to a conventional kiln. As such the process aims to concentrate, capture and reuse almost 100% of the CO₂ produced in a cost-effective manner. The medium-term goal is to further process the captured CO₂ with the help of renewable energy into products such as kerosene for air traffic.

Sweden: HeidelbergCement says that it will establish a 1.8Mt/yr carbon capture and storage (CCS) plant at its Slite cement plant in Gotland. It aims to achieve full-scale capture of the plant’s CO₂ emissions by 2030. In conjunction with the CCS plant project, Cementa will increase the share of biomass in the Slite plant’s fuel mix.

Chair Dominik von Achten said “Just a few days ago, we published new sustainability targets, underlining the importance of carbon capture, utilisation and storage (CCUS) as one key lever to almost halve our CO₂ footprint by 2030 compared to 1990, and achieve Net Zero by 2050 at the latest.” He continued “Slite CCS is the largest CCUS project yet in our group and the cement industry, and a model for what will be achievable with CCUS also beyond 2030. As this initiative contributes considerably to the climate ambitions of Sweden, and is a unique project for us in terms of scale, we are keen to make it happen.”

Sweden: Cementa has completed its feasibility study for a carbon capture and storage (CCS) system at Slite cement plant in Gotland. The producer says that it will now proceed to the next stage of the project, with the aim of producing climate positive cement from 2030. Sister company Norcem is currently building a 400,000t/yr CCS system at its Brevik cement plant in Norway. Cementa says that its new system will have four times the capacity of that at the Brevik plant, and reduce Sweden's total CO₂ emissions by 3%. One or more of 'several storage solutions' currently under development in the North Sea will serve to store the plant's captured CO₂ emissions.

General manager Giv Brantenberg said "With the knowledge we have built up through our pioneering project at Norcem in Brevik, we now have a good picture of how to move forward in Sweden. The Nordic countries have what it takes to lead the climate transition in the construction sector."

US: The US Department of Energy has granted Solidia Technologies US$2.1m in funding for the development and testing of carbonation methods for its Solidia Cement. Solidia will research synthetic supplementary cementitious materials (SCMs) production methods using direct CO₂ capture and utilisation.

CEO Russell Hill said “We are proud to partner with the US Department of Energy to continue innovating and ultimately deliver on our mission to provide commercially viable decarbonisation technologies and sustainable solutions for the global construction and building materials industries. The funding will advance our carbon capture, utilisation and storage (CCUS) technologies and synthetic SCMs that can be easily integrated into Portland cement-based concrete formulations, offering manufacturers a solution that is sustainable environmentally and economically.”

Germany: HeidelbergCement has accelerated its specific CO₂ emissions reduction target to 2030 to 400kg CO₂/t CEM compared with 1990 levels. This represents a 30% cut compared to 2021 levels and a 47% cut compared to 1990 levels. The previous target was 33% compared to 1990 levels. The company said that in the next eight years to 2030 its CO₂ emissions are set to decrease more strongly in percentage terms than in the last three decades.

The building materials producer made the announcement as part of a new set of medium-term sustainability and financial targets entitled ‘Concrete Promises’ that were presented at its Capital Markets Day event in late May 2022. The group plans to generate half of its revenue from sustainable products by 2030. Carbon capture, utilisation, and storage (CCUS) projects that have already been launched are expected to achieve a cumulative reduction of 10Mt CO₂ by 2030. By 2025, more than 70% of its debt will be covered by sustainable financial instruments. Among other things, the group plans to use a bond programme that it says is the first in the industry to be aligned with the climate goals of the European Union taxonomy.

Dominik von Achten, chair of the managing board of HeidelbergCement, said “We have the ambition, speed, knowledge, technologies and partners to lead the necessary change process in our sector. Our focus is on expanding our portfolio of sustainable products, reducing our CO₂ emissions quickly and significantly, proving that CO₂-free products are possible on a large scale, and creating a circular economy by consistently applying the principles of circularity. Our new sustainability targets for 2030 illustrate this ambition.”
