France: Vicat plans to test hydrogen electrolysis technology provided by Genvia for a pilot project at its Montalieu-Vercieu cement plant. Genvia made the announcement following a tour of its facilities by President Emmanuel Macron. It will be working with Vicat, Hynamics, a subsidiary of EDF group, and EDF Energy on the initiative. Other pilot projects have been announced with steel producers ArcelorMittal and Ugitech.

Genvia is a hydrogen production joint venture between French Alternative Energies and the Atomic Energy Commission (CEA), Schlumberger New Energy, VINCI Construction, Vicat Group and the Occitanie Region. It is developing and promoting solid oxide technology to enable industrial decarbonisation through hydrogen production, energy storage and fuel applications at scale.

Greece: Titan Cement has recorded sales of Euro1.26bn in the first nine months of 2021, up by 5% year-on-year from Euro1.2bn in the first nine months of 2020. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 4.3% to Euro220m from Euro229m, while its net profit rose by 41% to Euro81.9m from Euro58m.

During the third quarter of 2021, Titan Cement’s US low-carbon cement sales reached 50% of its total US cement sales. It also continued with hydrogen enrichment pilot studies in its cement kilns in Bulgaria and Greece.

Germany: Cool Planet Technologies and Hereon have signed a memorandum of understanding with Holcim Deutschland to deliver a carbon capture system for a carbon capture and storage (CCS) trial at the producer’s Höver cement plant in Lower Saxony. Cool Planet Technologies will install their system, which is based on Hereon’s PolyActive membrane technology. The system will have a capture capacity of 5600t/yr and operate from early 2022 to early-mid-2023. If successful, two subsequent expansions will increase the system’s capacity to 170,000t/yr, commencing operation in 2024, and 1.3Mt/yr, commencing in 2026.

The suppliers say that their membrane-based capture system is capable of reducing the energy intensity and eliminating the need for other chemical inputs in CCS.

Switzerland: Holcim Schweiz has partnered with Sweden-based Volvo Autonomous Solutions to test and develop automated electric dumpsters at its Gabenchopf quarry in the Siggenthal. The companies aim to develop a safe, efficient and sustainable dumpster for use in the cement industry.

CEO Simon Kronenberg said “We are very excited to be working with Volvo on this project. For us, this project means a further step towards realising our sustainability goals: in order to make a contribution to a sustainably built future, we continuously invest in measures to reduce our ecological footprint and look for solutions that are both innovative and sustainable."

Germany: Cemex Zement’s Rüdersdorf, Brandenburg, cement plant is to host a new 100t/day carbon capture installation. Cemex Zement will collaborate with UK-based Carbon Clean on a front-end engineering and design (FEED) study for the project. The system will combine captured CO₂ with sustainably sourced hydrogen in order to produce green synthetic hydrocarbons. The partners aim to increase the system’s CO₂ capture capacity to 300t/day by 2026, before finally scaling it up to 2000t/day.

Europe, Middle East, Africa and Asia regional president Sergio Menendez said “This project with Carbon Clean is the latest development in Cemex’s plan to achieve carbon neutrality at the Rüdersdorf cement plant by 2030, through our pioneering carbon neutral alliance with expert industrial consortiums. Carbon capture will play a fundamental role in the efforts to succeed at this goal and ensure our operations are more sustainable.”

World: A Systems Change Lab report on the state of climate change action has warned that the global cement industry is making insufficient progress towards its 2030 climate change targets and that a step-change in action is required. It recorded the carbon intensity of global cement production at 635kgCO₂/t in 2018 with the 2030 target of no more than 370kgCO₂/t. The rate of change over the previous five years was reported as being 2.9% but an annual rate of change of 22.5% would now be required to meet the 2030 target.

It also noted that emissions intensity from the cement industry had actually increased slightly in recent years. It reached this conclusion by using a different methodology from the Getting the Numbers Right (GNR) project. Instead it estimated the global emissions intensity by using global data on process emissions and energy data from the International Energy Agency and the GNR.

The report said that the cement sector would need to go beyond traditional mitigation options such as improving energy efficiency and switching fuels to meet its climate commitments. However, carbon capture utilisation and/or storage (CCUS) and novel cements were described as costly and immature. In its view, “Decarbonisation in the long term thus will depend on significant investments in research, development, and demonstration, alongside efforts to create a demand for low-carbon cements and policies to support investment in decarbonisation technologies.” It described both strategies as, “not yet fully mature in terms of technology development, costs and scaling.” The ‘critical enablers’ it identified to help the cement sector meet its target included stricter regulations, increased demand for low-carbon cement and investment in pilot and industrial scale projects looking at novel cements.

Overall, the report said that change towards averting climate change across 40 key areas in power generation, buildings, industry, transport, land use, coastal zone management and agriculture was not happening fast enough and that none were on track to meet their respective 2030 targets. Change was happening but not at the required pace. Systems Change Lab is a collaboration between the High-Level Climate Champions, Climate Action Tracker, ClimateWorks Foundation, the Bezos Earth Fund and World Resources Institute.

UK: The government has awarded funding to the planned HyNet North West low-CO₂ industrial cluster. The cluster will reduce industrial CO₂ emissions by 10Mt/yr in North Wales and North West England. It includes a planned 800,000t/yr carbon capture installation at Hanson UK’s Padeswood cement plant in Flintshire. The producer is currently carrying out a feasibility study at the plant. Parent company HeidelbergCement said that the project will play a ‘critical role’ in the UK’s transition to net zero CO₂ emissions by 2050.

Chair Dominik von Achten called the decision “A well-deserved recognition for the HyNet consortium and our colleagues working on carbon capture and storage (CCS) in the UK as part of this collaborative project. Cutting CO₂ emissions is a key priority for us, and we are delighted to add our Padeswood cement works to our growing range of CCS activities, as a key part of our pathway to reaching net zero.”

US: LafargeHolcim US and ECOncrete Tech have launched a research and development collaboration to design and manufacture a fully structural concrete scour protection unit for offshore wind turbines. The unit’s specifications include seabed stabilisation and promotion of the growth of marine organisms. The collaboration includes a large-scale pilot project to evaluate the ecological performance of units in an offshore environment. The US/Canada Binational Industrial Research and Development (BIRD) Energy programme are funding the project, which will conclude in May 2024.

LafargeHolcim US commercial excellence vice president Josep Maset said “There are many paths to achieving our net zero commitment, and most require innovative partnerships and out-of-the-box thinking. The work we’re doing with ECOncrete Tech is a notable example of searching for solutions that enable increased use of renewable energy in an environmentally responsible way.”

Spain/Norway: A team from Cartagen Polytechnic and Ostfold University College has demonstrated that Cementos La Cruz could reduce the cost of its concrete production by Euro1.45/m3, or Euro29,000/month by curing concrete with captured CO₂. EuropaPress has reported that the use of CO₂ would reduce the amount of cement required by 7 – 8%. This in turn would remove an estimated 4.6% of CO₂ from the concrete’s production.

Germany: Scientists at the University of Kassel in Hessen have launched a study into the use of ash from waste incinerators in precast concrete production. The Hessische Allgemeine newspaper has reported that a waste-to-energy plant in Kassel will provide the ash for concrete production in partnership with local companies Kimm Baustoffe and Gebäudeke Baustoff-Recycling. The study aims to produce pre-cast concrete elements containing at least 30% ash, beginning with paving slabs and noise barriers.

Project leader David Laner said that ash has the potential to help lower concrete’s carbon footprint. He said “So far, it has been put to lesser-value uses; we make a product out of it - upcycling instead of downcycling.”
