Germany: Cemex Deutschland has partnered with recycling service provider Alba to construct a new biochar production facility at its Rüdersdorf cement plant in Brandenburg. Named ALCE, the project will utilise biogenic waste to produce biochar, aiming to reduce greenhouse gas emissions from cement production. This initiative is part of the Carbon Neutral Alliance, targeting carbon neutral cement production at Rüdersdorf by 2030.

Both Limak Çimento and Cemento Yura revealed plans to work with hydrogen this week. Additionally, Lhyfe and Fives signed a deal to sell decarbonised products and services to industries, including cement, covering hydrogen production to combustion.

Türkiye-based Limak Çimento said that it had successfully conducted a hydrogen-enhanced alternative fuel test at its integrated Anka plant near Ankara. As part of the project it blended hydrogen with an alternative carbon-neutral fuel and then operated the plant’s kiln at a 50% substitution rate. The cement company says that the trial achieved a world first by feeding the hydrogen-enhanced fuel directly into the calciner instead of the main burner in the rotary kiln. According to local press, Air Liquide supplied grey hydrogen for the test, although this could be switched to green hydrogen in the future. As a reminder, ‘green’ hydrogen is produced by the electrolysis of water using renewable energy sources. ‘Grey’ hydrogen is made from steam reforming using fossil fuels.

Limak’s wider ambition is to use hydrogen-blended alternative fuels at all of its cement plants by 2030. By doing so it aspires to reduce its CO₂ emissions by 700,000t/yr. Its CEO Erkam Kocakerim remarked in mid-2023 that focusing on the carbon risks that energy-intensive industries might face exporting to the European Union (EU) paled in comparison to the potential payback from the green energy transition. At a climate change summit in mid-2023 organised by the United Nations and the Turkish government, he called for the Turkish Emission Trading System to be put into action as soon as possible, the creation of an updated renewable energy roadmap with renewable hydrogen, CCUS and renewable fuels, and the publication of a hydrogen and CO₂ country atlas. At the same time, he stated that the local cement sector could meet the EU’s 2030 emissions targets through the increased uptake of alternative fuels and blended cements.

Meanwhile in Peru this week Juan Carlos Burga, the general manager of Grupo Gloria subsidiary Cemento Yura, told the Gestión newspaper that its cement plant near Arequipa is preparing to start a green hydrogen trial in 2025. The catalyst for this is a solar power unit at the site that is currently scheduled for commissioning in early 2025. Once it is ready then the plant’s hydrogen project can use the renewable energy source to manufacture hydrogen and inject small quantities of it to stabilise the burning process and reduce the amount of coal used.

By contrast the memorandum of understanding that Lhyfe and Fives announced this week looks like the pair are marking their territory in the hydrogen supply and equipment chain for heavy industry. As part of the agreement the companies are targeting the metals, glass and cement industries and some other selected industrial heating processes and applications in Europe and North America. France-based Lhyfe develops, builds and runs green hydrogen production plants both for external clients and itself. It operates one plant at Bouin in France and is building other plants in France and Germany. However, the output of these sites is low. In spite of this, it says it is set to become the largest producer of renewable hydrogen in France in 2024. Fives, well known as a cement equipment supplier, says it has been a “technological leader in hydrogen for over 50 years” and that it sells “the widest range of hydrogen-proven burners available on the market to serve all industries.” The Lhyfe-Fives agreement follows a similar deal between Air Products and ThyssenKrupp Uhde Chlorine Engineers in 2020.

Projects in West Asia and South America such as those discussed by Limak Çimento and Cemento Yura are not necessarily where one might expect them to be. Typically all the sustainability news in the cement sector tends to be dominated by companies in Europe and North America. This is reflected in the continents that Lhyfe and Fives have targeted this week. Yet, the focus by Limak and Yura on hydrogen suggests that these companies are hunting for decarbonisation options that are cost effective ahead of potential legislative enforcement. Both appear to be using hydrogen as a fuel enhancer or additive rather than on its own.

We have reported upon a steady stream of hydrogen projects for the cement sector in the last year. These include Heidelberg Materials' study looking at using ammonia as a hydrogen source for fuelling cement kilns at its Ribblesdale cement plant in the UK, Fives work with Holcim at the La Malle plant in France and much work by Cemex such as the increase of its stake in green hydrogen production technology developer HiiROC in late 2023. As with Global Cement Weekly’s previous reporting on hydrogen, the jury is still out on whether it is a ‘goer’ for heavy industry at scale. An executive at Mitsubishi Heavy Industries told a conference in March 2024 that the infrastructure investment to support the use of hydrogen would cost over US$1Tn in the US and Europe alone. The head of Saudi Aramco then pointed out at the same event that oil and gas, for now at least, cost far less than hydrogen. Despite this, the projects keep coming.

Germany: Alcemy, manufacturer of low-carbon ‘Cem X’ cement, has raised US$10m to scale up its cement decarbonisation solution. The funding round will support research and development and Alcemy's entry into new markets, including the US, in 2024.

CEO Leopold Spenner said "With this additional nearly US$10m in funding and support from Norrsken VC, in addition to our first-round investors, we're paving the way to a low-carbon construction industry, one project at a time."

Germany: Berlin-based AI startup Alcemy, in partnership with German cement producer Spenner, has produced a commercially viable low-carbon cement alternative named ‘CEM X’. This product reportedly reduces carbon emissions by 65% and has less than 30% clinker content, according to the company. The composition incorporates a blend of 33% granulated blast furnace slag and 37% limestone.

Alcemy CEO Leopold Spenner said "With 'CEM X,' we have reached a significant milestone on our journey to decarbonising the cement industry.”

Germany: Heidelberg Materials, in partnership with Linde, is constructing a large-scale carbon capture and utilisation (CCU) facility at its Lengfurt cement plant, set to start operating in 2025. According to the company, it will be the first of its kind. The project is named Capture-to-Use (CAP2U) and will capture 70,000t/yr of CO₂.

Christian Knell, general manager of Heidelberg Materials Germany, said "With the amine scrubbing technology applied here in Lengfurt, we are demonstrating the capture and utilisation of CO₂ on an industrial scale for the first time in the cement industry in Germany.”

Germany: Heidelberg Materials has appointed Katharina Beumelburg as its Chief Sustainability & New Technologies Officer. She succeeds Nicola Kimm, who will leave the company on 31 August 2024. Beumelburg will take up her position on 1 October 2024.

Beumelburg joins Heidelberg Materials from SLB (formerly Schlumberger), where she has worked as the Chief Strategy and Sustainability Officer since May 2021. Previously, she spent over 15 years at Siemens, Siemens Energy, and Hydrogen Europe, focusing on business strategy and excellence as well as energy systems. She has studied Industrial Engineering and Mechanical Engineering and holds a PhD in Robotics and Automation from the University of Stuttgart.

Germany: Rohrdorfer has started operation of a new photovoltaic (PV) unit at its Rohrdorf cement plant near Rosenheim in Upper Bavaria. The rooftop PV installation comprises 1000 modules, covers around 2000m2 and has a peak output of 400kW. The construction time of the solar panels took five weeks. Modules supplied by Hecker Solar were installed by Elektro Ecker.

The cement plant has produced around one third of its electricity requirements via a waste heat recovery unit since 2011. Rohrdorf Group aims to generate 30% of its electricity from renewable sources as a whole by 2033.

Germany: Calix's subsidiary Leilac and Heidelberg Materials have formed a joint venture to build the Leilac-2 low emission cement demonstration plant at Heidelberg's Ennigerloh facility. Construction is set to begin in 2025, with the plant's commissioning scheduled for mid-2026. The Leilac-2 plant will showcase a module capable of capturing up to 100,000t/yr of CO₂ emissions from cement and lime production. Following construction and commissioning, Leilac-2 will be operated for up to three years to test the performance of the technology.

The project benefits from €16m in funding from the EU's Horizons 2020 programme and contributions from partner cement companies. Following construction, Heidelberg Materials may repay Leilac's capital contribution, and the partners will consider a full-scale commercial installation of Leilac technology at a Heidelberg plant. Plans for Leilac-3 envisage a significantly increased capture capacity, potentially capturing 0.5–1Mt/yr of CO₂.

Leilac CEO Daniel Rennie said "The formation of a joint venture with Heidelberg Materials for the Leilac-2 plant marks another important milestone for commercialisation of the Leilac technology. We look forward to continuing to collaborate with Heidelberg Materials to demonstrate and deploy cost-effective solutions to decarbonise cement production at commercial scale.”

China: KHD’s management team met in Nanjing in May 2024 to strategise on advancing decarbonisation in the cement industry. The meeting focused on industry needs and sustainable practices.

CEO Jianlong Shen said "We were pleased to welcome members of KHD leadership from around the world to Nanjing. Everyone who attended had the opportunity to take part in the discussion and share their ideas and suggestions for our next steps. We look forward to sharing more about our direction in due course as we continue on our collective journey to cement beyond carbon."
