It is the first Indian producer to instigate sustainability target-linked financial commitments.
Update on carbon capture in cement, September 2021
22 September 2021It’s been a good week for carbon capture in cement production with new projects announced in France and Poland.
The first one is a carbon capture and utilisation (CCU) collaboration between Vicat and Hynamics, a subsidiary of energy-provider Groupe EDF. The Hynovi project will see an integrated unit for capturing CO2 and producing methanol installed at Vicat’s Montalieu-Vercieu cement plant in 2025. It aims to capture 40% of the CO2 from the kiln exhaust stack at the plant by using an oxy-fuel method and installing a 330MW electrolyser to split water into oxygen and hydrogen for different parts of the process. The CO2 will then be combined with hydrogen to produce methanol with potential markets in transport, chemicals and construction. The setup is planning to manufacture over 0.2Mt/yr of methanol or about a quarter of France’s national requirement. The project was put forward under a call for proposals by the Important Projects of Common European Interest (IPCEI) program. Pre-notification of its participation in the program has been received from the French government and it is currently being evaluated by the European Commission. Vicat’s decision to choose its Montalieu-Vercieu plant for this project is also interesting since it started using a CO2ntainer system supplied by UK-based Carbon8 Systems there on an industrial scale in November 2020. This system uses captured CO2 from the plant’s flue gas emissions to carbonate cement-plant dust and produce aggregate.
The second new project is a pilot carbon capture and storage (CCS) pilot by HeidelbergCement at its Górażdże cement plant in Poland. This project is part of the wider Project ACCSESS, a consortium led by Sintef Energi in Norway that aims to cut carbon capture, utilisation and storage (CCUS) costs and to link CO2-emitters from mainland Europe to storage fields in the North Sea. The cement plant part in Poland will test an enzyme-based capture method using waste heat at the plant. Another part of the project will look at how the captured CO2 can then be transported to the Northern Lights storage facility in Norway including the regulatory aspects of cross-border CO2 transport. ACCSESS started in May 2021 and is scheduled to end in April 2025. It has a budget of around Euro18m with Euro15m contributed by the European Union (EU) Horizon 2020 fund.
HeidelbergCement also says that the second stage of its LEILAC (Low Emissions Intensity Lime And Cement) project at the Hannover cement plant is part of ACCSESS, with both testing of the larger-scale Calix technology to capture CO2 and the connected transport logistics and bureaucracy to actually get it to below the North Sea. That last point about Calix is timely given that US-based Carbon Direct purchased a 7% stake in Calix in mid-September 2021 for around US$18m. Whilst on the topic of carbon capture and HeidelbergCement don’t forget that the group’s first full-scale carbon capture unit at Norcem’s Brevik cement plant, using Aker Solution’s amine solvent capture technology, is scheduled for commissioning in September 2024. Another carbon capture unit is planned for Cementa’s Slite plant in 2030 but the proposed capture method has not been announced.
Other recent developments in carbon capture at cement plants include Aalborg Portland Cement’s plan to capture and store CO2 as part of the Project Greensand consortium. The overall plan here is to explore the technical and commercial feasibility of sequestering CO2 in depleted oil and gas reservoirs in the Danish North Sea, starting with the Nini West Field. The project is still securing funding though, with an Energy Technology Development and Demonstration Program application to the Danish government pending. However, the Danish Parliament decided in December 2021 to set aside a special funding pool to support a CO2 storage pilot project so this initiative seems to be making progress. If the application is successful, the consortium wants to start work by the end 2021 and then proceed with an offshore injection pilot from late 2022. How and when Aalborg Portland Cement fits in is mostly unknown but a 0.45Mt/yr capture unit at its Rørdal cement plant is tentatively planned for 2027. There’s also no information on the capture method although Aker Carbon Capture is also part of the Project Greensand consortium. Finally, also in September 2021, Chart Industries subsidiary Sustainable Energy Solutions announced that it had selected FLSmidth to help adapt and commercialise its Cryogenic Carbon Capture carbon capture and storage (CCS) system for the global cement industry.
All of this tells the cynics in the audience that a large international climate change meeting is coming up very soon. Most cement companies will likely want some good news to show off when the 2021 United Nations Climate Change Conference (COP26) dominates the media agenda in November 2021. Other observations to point out include that none of the projects above are full-scale industrial carbon capture installations, most of them are consortiums of one sort of another and that they are all subsidised or want to be. While hydrogen and CO2 networks get built this seems inevitable. Yet, we’re not at the stage where cement companies just order carbon capture units from a supplier, like they might a new clinker cooler or silo, without the need for long lists of partners. When this changes then carbon capture looks set to flourish.
On a final note, the UK is currently experiencing a shortage of commercially-used CO2. The reasons for this have nothing to do with the cement industry. Yet consider the constant doom-and-gloom about record global CO2 emissions and the sheer amount of effort going into reducing this by the projects mentioned above and others. Life has a sense of humour at times.

Federbeton publishes cement industry decarbonisation strategy
22 September 2021Italy: The Italian cement association Federbeton has launched its comprehensive plan for cement industry decarbonisation in line with the EU’s European Green Deal target of a 55% reduction in CO2 emissions between 1990 and 2030 and carbon neutrality by 2050. The strategy entails Euro4.2bn of total new investments andEuro1.4m/yr of extra operating costs across the industry. This will cover the adoption of transition technologies and the large-scale application of carbon capture and storage (CCS). The association says that while some such actions, such as alternative fuel (AF) substitution,are immediately available, others require further development. The sector’s primary fuel is petcoke, mainly imported from the Gulf of Mexico. As such, Federbeton has identified the 100% replacement of all fossil fuels with ‘low-carbon impact’ alternatives as a means of reducing the industry’s carbon footprint by 12% achievable in the short term. Renewable green hydrogen use can cut a further 3% of CO2 emissions, an energy transition to renewable sources can cut 5%, clinker factor reduction can cut 10%, alternative raw materials in clinker can cut 6%, CCS can cut 43%, supply chain and logistics changes can cut 16% and the optimisation of construction can cut the remaining 5%.
President Roberto Callieri said “The cement and concrete supply chain wants to be one of the protagonists of the ecological transition.” He added “Only with adequate and immediate support tools will it be possible to prevent the impoverishment of the industrial fabric, preserve the competitiveness of the supply chain and prevent relocation. Last but not least, a new environmental culture must be shared, based on dialogue and no longer on the preconceived opposition to any choice of industry.”
Vicat and Hynamics to produce methanol from captured CO2 at Montalieu-Vercieu cement plant
16 September 2021France: Vicat’s Montalieu-Vercieu cement plant will host a carbon capture and storage (CCS) installation and methanol plant under a joint project by Vicat and Groupe EDF subsidiary Hynamics known as Hynovi. The project aims to achieve 40% carbon capture at the plant. A 330MW electrolyser will convert captured CO2 to methanol through oxycombustion. Commisioning of the entire system is scheduled for 2025. The partners said that Hynovi may subsequently be taken up by cement plants globally.

The company expressed its commitment to reducing its carbon footprint and fossil fuel dependence.
Cemex UK relaunches pallet recovery service
09 September 2021UK: Cemex UK has relaunched its used pallet collection service. The scheme aims to reduce timber waste in its supply chain, according to the company. It forms part of its Future in Action – Committed to Net Zero CO2 climate action strategy. Its partner ELM will collect stockists’ pallets free of charge for refurbishment and return to Cemex UK. It will reuse all repaired pallets and recycle those damaged beyond repair.
Packed cement sales manager Graeme Barton said “We want to make life easier for our merchants to work with us to reduce waste. We’d like to make pallet recovery part of the standard delivery process, as many pallets still end up in landfill. It is increasingly costly to dispose of pallet waste and there is far greater value to be gained by recycling and reuse. Rising timber costs, combined with pallet shortages, means there is a heightened need to conserve and maintain pallets throughout the supply chain. Recovery is considerably more cost effective than buying new replacements.” He added “Pallets are a standard format in transporting building products and contribute a significant financial and environmental cost which needs to be captured by the user. We saw a similar situation with supermarkets and plastic bags, but we’d rather not wait for legislation to enforce this; we’d really like to make a difference now with preventative action. The pallet recovery service is regenerative by design and aims to support the key principals of the circular economy to benefit business, society and the environment. If we all pull together it will have a significant impact across the whole supply chain.”
Anhui Conch signs CO2 trading agreement with Shanghai Environmental Energy Exchange
08 September 2021China: Anhui Conch has signed a CO2 trading agreement with Shanghai Environmental Energy Exchange (SEEE). The deal takes place within the context of Shanghai’s CO2 trading pilot scheme. Anhui Conch says that it will not only facilitate the promotion of carbon allowance asset scheduling and carbon asset market transactions, but also provide accreditation and CO2 management system certification. It says that SEEE will help it to better assume the role of a leading enterprise in the ‘dual-carbon’ field of the cement industry.
Anhui Conch says that it is focusing on developing a full-process carbon footprint monitoring system. It has begun researching the utilisation possibilities of captured carbon with academic partners.
Cemex launches sustainability-linked financing framework
08 September 2021Mexico: Cemex has launched a sustainability-linked financing framework. It says that it is the ‘most comprehensive’ such framework in the building materials sector. The framework further aligns Cemex’s corporate sustainability commitments to its financing strategy, as part of its ‘Future in Action’ program. It establishes Cemex’s guiding principles when issuing new sustainability-linked financing instruments, including public bonds, private placements, loans, derivatives, working capital solutions and other financing instruments. Sustainalytics, an independent company that specialises in providing environmental, social and corporate governance research, ratings and data to institutional investors and companies, validated the framework’s alignment with the Sustainability-Linked Bond Principles, the International Capital Market Association’s Climate Transition Finance Handbook and the Loan Market Association’s Sustainability-Linked Loan Principles.
“Climate change is one of the biggest challenges of our time, and we will continue to address it as a fundamental component of our business strategy,” said Maher Al-Haffar, Cemex's chief financial officer. “Cemex is committed to increasing the role sustainable finance plays in its capital structure by potentially linking the cost of financial instruments to the achievement of targets, directly aligning our corporate finance strategy to sustainability commitments and further contributing to a low-carbon future.”
Cemex has included three key performance indicators in the framework: net CO2 emissions per tonne of cementitious product, clean electricity consumption and alternative fuels rate. All of them were qualified by Sustainalytics and deemed aligned with the company’s climate action strategy. Cemex currently has a 2030 target of reaching below 475kg/t of CO2 for cementitious products.
