UK: HeidelbergCement subsidiary Hanson has installed a solar and wind-powered hydrogen generation demonstration unit at its Port Talbot Regen ground granulated blast furnace slag (GGBFS) plant in Port Talbot in Neath Port Talbot. The company says that the project is part of a collaboration with Swansea University’s Energy Safety Research Institute under the European Research and Development Fund’s Reducing Industrial Carbon Emissions initiative. The hydrogen generated by the installation will replace natural gas in the GGBFS plant’s burners.

Head of sustainability Marian Garfield said, “It is estimated that cement is the source of just under 2% of UK CO₂ emissions. With demand for cement and cement replacement products predicted to increase by 25% by 2030, researchers and industry are working hard to reduce the level of CO₂ emissions associated with production. As a leading manufacturer, we take our responsibility very seriously. In the UK we have already achieved a 30% reduction in CO₂ emissions since 1990 across the business and have set an ambitious new target of a 50% reduction by 2030 from the same baseline. We are constantly looking to improve energy efficiency and carbon reduction at our cement and Regen GGBFS plants, so we are delighted to be involved with this innovative research project.”

The European Union (EU) Emissions Trading Scheme (ETS) looked like it might be about to hit Euro40/t this week. It still might. You can blame it on the current cold front bringing snow to much of Northern Europe and the bedding into of the fourth phase of the ETS that started in January 2021. In early 2020 analysts were generally predicting an average price of around Euro30/t by 2030 bolstered by volatility in the price due to the start of the coronavirus pandemic. Yet the price recovered and so did the European Commission’s resolve to push through its European Green Deal. By mid-December 2020 the price had shot past Euro30/t and analysts were forecasting average prices of well over Euro50/t by 2030. Depending on one’s disposition this is the rate at which either serious decarbonisation attempts will begin to be viable for commercial companies, or the point at which more plants simply close.

One group which is well aware of the EU ETS and its consequences upon the cement industry is Cembureau, the European cement association. Some of its current lobbying efforts have been directed at trying to shape how the Carbon Border Adjustment Mechanisms (CBAM) will appear in legislation proposals in June 2021. Its argument boils down to protecting its members from carbon leakage both in and out of the EU’s borders and maintaining free allocation until 2030 to ease the transition to a lower carbon economy. The former should find common ground. However, calls for a CO₂ charge exemption for EU exporters may perplex environmentalists, who might wonder how this could possibly encourage third party countries to introduce their own carbon pricing schemes. The latter is clearly pragmatism for an industry saying that it is facing change at a pace that may be too rapid for it to cope with. Concrete products do carry sustainability advantages over other building materials. Wiping out swathes of the region’s production base, simply because one knows exactly how much CO₂ they emit compared to rival building materials that one doesn’t, may not help the EU reach its climate commitments by 2050. As if to underline this fear, another European clinker line was earmarked for closure this week when Lafarge France announced the planned conversion of the Contes cement plant into a terminal.

Figure 2 above puts the situation into a global perspective, showing that Cembureau’s members were responsible for below 7% of cement production in 2018. China produced an estimated 55% of global cement production in the same year. In terms of overall CO₂ emissions across all sources, the International Energy Agency (IEA) estimated that China produced 30% of CO₂ emissions in 2018.

It seems odd then that the introduction of an interim ETS in China at the start of February 2021 didn’t receive more global news coverage. The new scheme covers 2225 power companies across the country. It follows pilot regional schemes that have run since 2011, covering seven provinces and cities including Beijing, Shanghai and Guangdong. Previously, the country’s largest local carbon market, the China Emissions Exchange (Guangzhou), was based in Guangdong province and it included power generation, cement, steel, and petrochemical sectors. State news agency Xinhua reports that this scheme reduced carbon emissions from these industries by 12% from 2013 to 2019. The new national ETS is expected to include cement and other industries at a later stage.

Commentators in the European press have pointed out that the Chinese national ETS is actually planning to make an effort on transparency and to force companies to publish their pollution data publicly. Yet, they’ve also said that the data may be inaccurate anyway, echoing the usual Western fears about Chinese figures. Other concerns include the method of giving out pollution permits rather than allocating them by auction as in other cap and trade systems, which could reduce the incentive to reduce emissions. It’s also worth pointing out that carbon was priced at US$6/t under the Chinese system compared to around US$35/t in the EU and US$17/t in California, US at the end of 2020. At this price it seems unlikely that the Chinese national ETS will encourage much change without other measures.

The EU and Chinese ETS are at different stages but the differences in scale are stark. When or if the Chinese one goes national across those eight core industries it will likely leapfrog over the EU ETS and become the world’s largest with an estimated 13,235MtCO₂e under its purview. By contrast, the EU ETS manages 1816MtC0₂e according to World Bank data. The kind of dilemmas Cembureau and others are tackling with the EU ETS such as carbon leakage and how fast to tighten the system against heavy emitters are illustrative to other schemes in China and elsewhere.

Europe/North America: Switzerland-based LafargeHolcim and US-based Schlumberger plan to study the feasibility of carbon capture and storage (CCS) systems at two cement plants in Europe and North America. The companies say that the partnership is intended to as a precursor towards the deployment of large-scale CCS solutions.

LafargeHolcim’s chief sustainability officer Magali Anderson said, “Today’s announcement is further proof of LafargeHolcim’s environmental leadership and commitment to pioneer new solutions to reduce carbon emissions on our journey to become a net zero company. Our partnership with Schlumberger, the world’s leading provider of technology to the global energy industry, will bring new advances in storage that could be replicated at scale across our sites.”

US: The US Department of Energy has awarded a grant to Cemex USA, UK-based carbon capture and storage (CCS) specialist Carbon Clean and Oak Ridge National Laboratory. The grant covers the implementation of a CCS system at Cemex USA’s Victorville cement plant in California, in addition to the development of a commercially viable carbon utilisation solution. The producer says that the study is due to last 30 months.

President Jaime Muguiro said, “Cemex is committed to being part of the solution to reduce carbon emissions globally and to deliver net-zero CO₂ concrete to all of our customers by 2050. We cannot achieve these aims without innovative technology and collaborative relationships with both public and private organizations who share a commitment to climate action. This grant gives us an excellent opportunity to further develop a new technology to help us all reach our goals.”

Colombia: LafargeHolcim subsidiary Holcim Colombia has launched Eco, a cement bag label detailing products’ CO₂ emissions reduction by comparison to Ordinary Portland Cement (OPC), on its Boyacá Súper Fuerte and Holcim Maestro cements. The La República newspaper has reported that the labels signal the company’s commitment to the Business Ambition for 1.5°C anti-climate change initiative.

Executive president Marco Maccarelli said that the launch is one more step on company’s path towards Net Zero and sustainable construction, engaging the entire value chain.

Germany: HeidelbergCement, Australia-based Calix and a European consortium have chosen the Hanover cement plant in Lower Saxony for the second phase of the LEILAC (Low Emissions Intensity Lime And Cement) carbon capture and storage (CCS) project. The installation will capture 20% of the plant’s capacity or 100,000t/yr of CO₂. The project will take place in three phases, with design completed by June 2021, a complete demonstration installation before the end of 2023 and project completion in 2025. The group previously installed a 25,000t/yr LEILAC CCS system at its Lixhe plant near Liege in Belgium, which completed its test phase in 2020.

Chair Dominik von Achten said, "The LEILAC technology has the potential to enable the cement and lime industries to efficiently capture their process emissions on an industrial scale. The pilot project in Hanover is one of several promising CO₂ capture technologies that we are currently testing at full speed within the HeidelbergCement Group."

Canada: Lehigh Cement and the International CCS Knowledge Centre are conducting a feasibility study looking at carbon capture and storage (CCS) at the Edmonton cement plant in Alberta. The project aims to find out whether capturing 90 – 95% of the CO₂ from the plant’s flue gas is viable. Completion of the study is scheduled for the autumn of 2021.

The Lehigh CCS Feasibility Study will consider an engineering design using carbon capture technology owned by Japan-based Mitsubishi Heavy Industries Engineering (MHIENG), part of MHI Group. The KM CDR process, which is being deployed at 13 commercial plants globally, will be examined for integration with Lehigh’s plant and output specifications, such as a flue gas pretreatment system and the carbon capture and compression process.

The aims of the study are to: deliver a Class 4 cost estimate; to work with a capture technology provider (MHI Group) to perform engineering design tailored to the Lehigh plant; to manage the process and engage third parties, as necessary; to complete a detailed business case; and to develop the budget for Front End Engineering Study (FEED). The project has received US$1.4m in funding from Emissions Reduction Alberta (ERA) through its Partnership Intake Program.

Canada: LafargeHolcim subsidiary Lafarge Canada, Svante and France-based Total have completed Phase 2 of the CO₂MENT carbon capture and storage (CCS) project at Lafarge Canada’s Richmond cement plant. The completed phase consisted of construction and installation of the CO₂MENT technology to capture and filter the flue gas. Lafarge Canada said that Phase 3, scheduled for construction over the next three years, will include the installation of a liquefaction unit, the development of an expansion project to further reduce emissions and a business case review for further expansion across the Lafarge network

Western Canada president and chief executive officer Brad Kohl said “This has been a turbulent year for business and people due to the Covid-19 pandemic with many large scale projects being put on hold, but the perseverance that the people working at the Richmond cement plant continue to show is evident in the success of Project CO₂MENT.” He added “To continue leading change in the building materials industry means we are always looking to partner with like-minded thought leaders such as Svante and Total. This partnership is showcasing our drive towards a net-zero future, and we are seeing this vision become a reality right now with the completion of this phase.”

France: Vicat started using a CO₂ntainer system supplied by UK-based Carbon8 Systems at its Montalieu-Vercieu cement plant in November 2020. It uses captured CO₂ from the unit’s flue gas emissions to carbonate cement-plant dust and produce aggregate, which can then be used to make products such as concrete. The system has particular relevance for a plant burning alternative fuels due to the additional chlorinated dust created compared to the use of conventional fossil fuels. The company says it is the first European cement producer to use the process at an industrial scale. Previously, Carbon8 Systems said that its CO₂ntainer would process and convert up to 12,000t of cement bypass dust in its first phase of operation.

Vicat Group scientific director Laury Barnes-Davin said, “We were drawn to Carbon8 Systems’ two-part technology: capturing the CO₂ that Montalieu emits, and using it to produce an aggregate that can be marketed in the construction industry. It opens up great potential for our operations not just in France but also in all the countries where we work across the globe.” The group hopes to reach a 100% alternative fuel substitution rate in France by 2024.

Spain: The Spanish cement association Oficemen has targeted a 43% emissions drop by 2030 across its entire value chain compared to 1990 levels. The objective has been published as part of the association’s sustainability roadmap to 2050. It is a tightening of the previous target of 27% by 2030. Oficemen intends to meet the tougher reduction by using the so-called 5C approach - clinker, cement, concrete, construction and built environment, and (re)carbonation – as detailed by Cembureau, the European Cement Association. Oficemen also revealed that it is working with the Spanish Technological Platform for CO₂ (PTECO₂) on identifying potential locations for storing captured CO₂. Hugo Morán, Secretary of State for the Environment, participated remotely with the launch event.

Oficemen also reports that Spanish cement consumption fell by 12% year-on-year to 12.2Mt in the first 11 months of 2020. Exports declined by 5%.
