It’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.

Mexico: Cemex has signed the Business Ambition for 1.5°C commitment led by the We Mean Business Coalition in partnership with the Science Based Targets initiative and the United Nations (UN) Global Compact. With this commitment in place the company has also joined the Race to Zero campaign of the UN Framework Convention on Climate Change. All members of the Race to Zero coalition pledge to reach net-zero emissions by 2050 at the latest, in line with global efforts in limiting global warming to 1.5°C. Cemex says that these objectives align with its Future in Action programme to reduce its carbon footprint by delivering net-zero concrete globally by 2050.

“Cemex’s commitment to Climate Action runs deep and we are excited to partner with prominent global organisations to deliver on this challenge. Implementing climate solutions require active collaboration between industry, governments, non-governmental organisations and multilateral agencies, and we intend to continue to play an active role in these efforts. We encourage others to join us in this important challenge”, said Fernando A. González, the chief executive officer of Cemex.

In addition, Cemex has submitted its new 2030 target of below 475Kg CO₂/t of cementitious product for validation to the Science-Based Targets initiative as part of its commitment to fulfil its ambition of carbon neutrality by 2050.

Germany: HeidelbergCement has signed the Science-Based Targets Initiative’s (SBTi) Business Ambition for 1.5°C commitment and joined the United Nations (UN) Framework Convention on Climate Change Race to Zero campaign. The former entails a commitment to limiting global warming to 1.5°C and achieving net zero carbon emissions by 2050. Race to Zero membership entails a positive commitment to beginning the transition to a decarbonised economy before the UN Climate Change Conference of the Parties in November 2021.

Chair Dominik von Achten said “As one of the world's leading building materials producers, we are continuously increasing our efforts in the global fight against climate change. We are working on all levels to reach climate neutrality – within our operations as well as through associations and initiatives such as the Race To Zero campaign. Every effort brings us closer to our goal.”

Cameroon: Two cement trucks masquerading as belonging to a United Nations agency have been seized by customs officials. The smugglers were pretending to be transporting food and pharmaceutical products in transit to Chad, according the Ecofin Agency. The cement is believed to have originated from Nigeria. The operation by customs authorities was part of the ongoing Halcomi (halte au commerce illicite) initiative.

Switzerland: LafargeHolcim has committed to accelerate the impact across its United Nation (UN) Sustainable Development Goal (SDG) activities, and disclose its progress.

Chief Sustainability Officer (CSO) Magali Anderson said, “As we celebrate the fifth anniversary of the Paris Agreement, it is more important now than ever for companies and governments to unite around climate action and the SDGs. That’s why we set ourselves the most ambitious 2030 climate targets in our industry, joining the Business Ambition for 1.5°C. Decarbonising business is vital, but it’s not enough. We are accelerating our overall commitment to the SDGs to build a world that works for people and the planet.”

Cemex last week. HeidelbergCement and LafargeHolcim this week. China yesterday. One can’t seem to move for major building materials companies (or their owners) issuing carbon neutral strategies at the moment. This week HeidelbergCement first launched its ‘Beyond 2020’ plan, a mixture of financial, portfolio and sustainability goals. Then, LafargeHolcim said that it had signed a pledge with Science-Based Targets (SBT) towards meeting intermediate targets by 2030. Last night, President Xi Jinping told the United Nations (UN) General Assembly in New York that China was aiming to hit peak emissions before 2030 and carbon neutrality by 2060.

The timing of these various sustainability goals are directly or indirectly linked to Climate Week NYC, a notable annual event on the climate change calendar that is taking place at the moment. So it’s a good time for large-scale industrial CO₂ emitters, like building material producers, to have something positive to say.

China’s announcement steals the limelight given that the country produces around half of the world’s cement and holds a higher share of clinker production capacity. Western media has pointed out the geopolitical implications of Xi’s statement that was delivered shortly after a speech by US president Donald Trump, a notable climate change sceptic. Xi’s speech didn’t contain any details so it may simply have been an attempt to demonstrate global leadership. Yet if the Chinese government makes a go of it, the effect could be profound. Data from the Centre for International Climate and Environmental Research (CICERO) shows that the Chinese cement industry emitted an estimated 782Mt CO₂ in 2018 compared to 1.50Gt CO₂ from the cement industry globally and 37.1Gt CO₂ from all human-related sources. In other words, the Chinese cement industry was responsible for 2% of all CO₂ emissions in 2018. And this industry is mostly owned by a government that has just publicly declared a carbon neutral target.

In some ways the other announcements, by the western-based multinational building material companies, are even more radical since these producers are subject to market forces. These companies don’t have to do this. They also contain more specifics than Xi’s words so far.

HeidelbergCement says it has brought forward its CO₂ emissions target for 2030 of 525kg CO₂/t (specific net CO₂ emissions per tonne of cementitious material) to 2025. That’s a 30% decrease from 752kg CO₂/t in 1990. Its new goal for 2030 is below 500kg CO₂/t. The main emission reduction methods it outlines include: increased use of alternative raw materials and fuels; increased use of secondary cementitious materials to reduce the clinker factor of cement; investment in plant efficiency and CO₂ reduction at the plant level; and increased share of low-carbon concrete products.

Chart 1 above outlines HeidelbergCement’s thinking post-2030 with further reductions to CO₂ emissions mainly achieved through circular economy methods and different carbon capture techniques. Two points to hold in mind here. One: note the current uncertainty about which route will provide the biggest share of the reduction. Two: this chart considers concrete, not cement.

LafargeHolcim’s announcement was that it has joined Science Based Targets initiative (SBTi) ‘Business Ambition for 1.5°C.’ It says that by doing so it has become the first global building materials company to sign the pledge with intermediate targets for 2030, validated by SBTi. This is slightly confusing given that other building materials companies have had different dealings with the SBT as it has worked towards its current scheme. Earlier this month, for example, we reported that Taiwan Cement had started an SBT project in 2019 and had some targets approved by the SBTi in June 2020. Grupo Cementos de Chihuahua (GCC) said it was joining SBTi at the start of 2020 and HeidelbergCement reported its SBTi approved targets in mid-2019. Finally, India-based Dalmia Cement is also on the SBTi ‘Business Ambition for 1.5°C’ list but it is a stretch to describe it as a ‘global’ company.

The core of LafargeHolcim’s statement is a further reduced target for CO₂ intensity in cement of 475kg CO₂/t by 2030. So far it’s decreased its CO₂ intensity by around 23% to 516 kg CO₂/t in 2019 from ~730kg CO₂/t in 1990. There’s less looking ahead after 2030 compared to HeidelbergCement but the measures outlined until then include: more use of low-carbon and carbon-neutral products; increased use of alternative raw materials and fuels; doubling waste-derived fuels in production to reach 37%; greater use of calcined clay and developing novel cements with new binders; and operating the company’s first net zero CO₂ cement production facility.

Many of the various networks and initiatives across the climate action community came together in June 2020 as part of the UN backed ‘Race To Zero Campaign,’ an attempt to align the disparate leading net zero initiatives ahead of the 26th United Nations Climate Change Conference (COP), due to take place in November 2021 in Glasgow, Scotland. This swirl of different net zero schemes also partly explains the confusion over the different organisations backing sustainability targets that companies can sign up to. So it’s a good thing to see closer collaboration here.

More cynical readers will have latched on to president Xi’s opportunity to show up President Trump in the climate change action stakes. They may also prefer news stories about activist investors prompting change at shareholder-owned companies as they increase their portfolios or stories like Morgan Stanley’s announcement this week that it has a new commitment to reach net-zero financed emissions by 2050. If the investment bank actually means it and other financiers follow suit then the fiscal incentives for net zero draw closer and the rest should follow. Moneys talks… and hopefully CO₂ stays buried in the ground.

Myanmar: Switzerland-based LafargeHolcim says it is liquidating its subsidiary in Myanmar. The group says it decided in 2017 to exit its operations in Myanmar. Subsequently, it wound the company down in 2018, with no local employees and no product sales. Its cement repacking plant in Thilawa special economic zone (SEZ) originally opened in 2014.

The announcement follows the discovery by the Sonntags Zeitung newspaper of military links (Tatmadaw) with two companies allegedly linked to a sale of the assets. In mid-2019 the United Nations (UN) recommended that multinational companies operating in the country, “should conduct heightened due diligence to ensure they are not benefiting the Tatmadaw,” following the persecution of the mainly-Muslim Rohingya in Rakhine state from mid-2017.

Nepal: Ashden Environment and the United Nations Science, Technology and Innovation Forum have awarded Build Up Nepal their respective highest awards for its low-cement disaster-resistant concrete blocks. The Nepal Time newspaper has reported that the blocks contain a mix of 10% cement, 40% clay and 50% sand, all sourced from near Build Up Nepal’s Mitra Marg, Patang plant. The company has supplied its unique building materials to projects in 300 different communities, including the construction of 4500 homes. It says that the blocks, reinforced with iron rods, have a greater earthquake resistance than concrete.

Build Up Nepal said, “Interlocking brick is a highly suitable construction technology in Nepal, reducing the cost of construction as well as the carbon footprint of building a house. With this technology Nepal's houses can be stronger, more affordable and its air cleaner.”

India: Cement producers and the World Business Council for Sustainable Development (WBCSD) have launched the Indian Cement Sector SDG Roadmap. The planning framework uses the United Nation’s (UN) sustainable development goals (SDG) to set a series of goals in energy and climate, people and communities, the circular economy and natural resource management. It is intended to contribute to the UN’s 2030 Agenda for Sustainable Development.

This initiative has been convened by nine cement companies: ACC, Ambuja Cement, CRH, Dalmia Cement (Bharat), Heidelberg Cement, Shree Cement, Orient Cement, UltraTech Cement, Votorantim Cimentos. It is also partially funded by the Swiss Agency for Development and Cooperation (SDC).

Notable goals from the roadmap include promoting railway and waterway transport networks, improving transport safety, increasing the use of blended cements and encouraging the use of alternative fuels. The framework also plans to increase the number of women in the indsutry workforce at every level from entry to board.

Mexico: Cemex has adopted the United Nations (UN) Sustainable Development Goals (SDG). It has prioritised five goals from the charter that connect with the company’s business and represent an opportunity to contribute to the UN 2030 Agenda. These five goals are focused on the promotion of decent employment and economic growth (SDG 8), innovation and infrastructure development (SDG 9), climate change mitigation (SDG 13), environmental and ecosystem conservation (SDG 15) and the advancement of sustainable cities and communities (SDG 11). Cemex plans to continue embedding the UN SDGs into its business processes to create systemic change, increase engagement, promote a sense of purpose and raise awareness among its stakeholders.
