UK: Heidelberg Materials' Ribblesdale cement works in Lancashire is participating in a pioneering study to assess the use of ammonia as a hydrogen source for fuelling cement kilns. This 12-month feasibility project, conducted in collaboration with engineering consultants Stopford and Cranfield University, has received funding from Innovate UK through its UK Research and Innovation fund.
The research aims to investigate ammonia as a potentially energy-dense, cost-effective hydrogen carrier for cement manufacturing and other industries. Building on Ribblesdale's successful demonstration of using hydrogen in a net-zero fuel mix for a cement kiln, the new project will focus on the most efficient methods for on-site 'cracking' of ammonia to release hydrogen as kiln fuel.
Marian Garfield, Sustainability Director at Heidelberg Materials UK, said “We have already proved the success of using hydrogen as part of a lower carbon fuel mix, but its storage and transportation are currently technically challenging and expensive. Ammonia could offer a more viable hydrogen source that enhances fuel usage and reduces CO2 emissions. If successful, this project will pave the way for further investigations into the commercial viability of using ammonia as a hydrogen carrier for combustion in cement production and beyond.”
France: Fives Group has partnered with Holcim to decarbonise its cement production processes. Fives conducted successful hydrogen tests at the La Malle site in France, achieving over 50% hydrogen substitution in cement production. This result also enabled a significant increase in the use of alternative fuels while still maintaining cement quality. The group has also developed a digital model to tailor this process to each cement plant's unique requirements.
Germany: Rohrdorfer Zement has fired up a pilot clay tempering unit at its Rohrdorf cement plant in Bavaria. The project has received Euro8.65m in funding from the German Federal Ministry for Economic Affairs and Climate Action and the EU. It is one of a number of industrial projects under the EU’s Euro800bn NextGenerationEU post-Covid-19 economic recovery instrument. Sources of heat for the pilot unit at the Rohrdorf cement plant include waste heat from the plant’s clinker line. If the pilot succeeds, the introduction of tempered clay into cement production at the site will follow. This will entail the construction of an on-site full-scale clay tempering plant. Rohrdorfer Zement says that this would reduce the plant’s CO2 emissions by 16 – 18%, or by 30% if it achieves carbon neutral clay tempering through the use of green hydrogen.
Rohrdorfer’s dedicated Net Zero Emissions Labs team is working to turn the Rohrdorf cement plant carbon neutral by 2038. Other initiatives include the installation of carbon capture systems at the Rohrdorf plant and another in Austria, and participation in the H2-Reallabor Burghausen hydrogen partnership.
Regarding the latest pilot, Rohrdorf Net Zero Emissions Labs project leader Helmut Leibinger said “As a cement component, tempered clays make a significant contribution to CO2 mitigation. With the pilot project of process-integrated tempered clay, we are taking not just a step in our decarbonisation roadmap, but a leap.”
Spain: Cemex España has announced its participation in the HYIELD consortium, which plans to build a waste-to-hydrogen demonstration plant at the producer’s Alcanar cement plant in Catalonia. The demonstration plant will process a total of 2000t of biogenic waste to produce 400t of green hydrogen for use as fuel, fertiliser and for other applications. The trial commands Euro10m in funding from the EU’s research and innovation funding programme Horizon Europe. Parent company Cemex believes that the technology being demonstrated at Alcanar has the potential to process 300Mt/yr of waste across Europe and produce 30Mt/yr of hydrogen.
Cemex’s Europe, Middle East and Africa regional president Sergio Menendez said “As part of its drive towards reaching net zero by 2050, Cemex is committed to partnering with like-minded organisations to explore the very latest innovations in more sustainable technology that can support the cement production process. We are proud to provide one of our cement plants in Spain as the location for the HYIELD trial and excited to see the outcomes from this research and development project.”
Cemex Ventures raises stake in HiiROC
20 December 2023UK: Cemex’s corporate venture capital and open innovation unit Cemex Ventures has increased its stake in green hydrogen production technology developer HiiROC. Cemex Ventures described hydrogen as a ‘breakthrough approach’ to CO2 reduction in the cement sector.
Head of Cemex Ventures Gonzalo Galindo said "This news comes at a critical moment, when COP28 has brought the world together to address and refocus the climate agenda and buckle down on the responsibility of governments and private corporations to deliver on their decarbonisation objectives ahead of 2030. With our increased investment in HiiROC, we are especially proud to be number one in the use of hydrogen in the cement sector and are committed to keep scouting new ways to deploy hydrogen at a grand scale at Cemex’s 60 cement and grinding plants.”
Holcim Mexico to trial hydrogen injection in cement kilns
18 December 2023Mexico: Holcim Mexico has concluded a deal to set up a trial of hydrogen injection in kilns at one or more of its seven cement plants in Mexico. The producer says that the technology will optimise combustion processes and facilitate the increased substitution of alternative fuel.
Cemex raises European reduced-CO2 cement volumes to 20% of sales
11 December 2023Europe: Cemex says that sales of reduced-CO2 cement from its Vertua range comprised 20% of its sales in Europe by volume in November 2023. The range includes Vertua Supreme cement, which offers 55% lower CO2 emissions than ordinary Portland cement (OPC). Cemex attributed its success in developing Vertua Supreme cement to advances in product design and manufacturing technology, including the use of hydrogen in its cement kilns.
US: Summit Materials has entered into a memorandum of understanding (MOU) with hydrogen producer PCC Hydrogen (PCCH2). The MOU establishes an alliance to develop a fuel replacement strategy for Summit Materials’ cement production. PCCH2 will build a hydrogen plant to supply green hydrogen at a cement plant belonging to Summit Materials subsidiary Continental Cement.
Continental Cement president David Loomes said "Continental Cement has a longstanding commitment to environmental stewardship, seeking out opportunities to develop innovative practices and differentiated solutions to build a better tomorrow. Our company has signed on to the Portland Cement Association (PCA)'s Roadmap to Carbon Neutrality, with a goal of achieving carbon neutrality across the value chain by 2050. By coupling PCCH2's hydrogen production process with our cement manufacturing know-how, we are taking a bold stride towards achieving that goal, while continuing the push to cost-effective decarbonisation of cement manufacturing."
India: A report by the Council on Energy, Environment and Water (CEEW), funded by power provider BP, has estimated that India’s cement and steel sectors will require capital expenditure (CAPEX) investments of US$627bn in order to reach net zero CO2 emissions. The report stated that waste heat recovery (WHR) and other efficiency-enhancing upgrades to cement plants can immediately reduce the industry’s emissions by 32%.
United News of India has reported that CEEW CEO Arunabha Ghosh said "Incentivising renewable energy will play a pivotal role in decarbonisation, through lower or no transmission charges at central and state levels. The government of India should develop a policy for and expedite the establishment of a carbon capture, utilisation and storage ecosystem to abate more than half of the emissions from the existing steel and cement plants.” Ghosh added “Since hydrogen will play a key role in its implementation, the next phase of the National Green Hydrogen Mission should focus on this agenda."
Spain: Switzerland-based Synhelion and Cemex España plan to build a new clinker plant near Madrid. The plant will use Synhelion’s synthetic fuel to produce clinker from clay and crushed sand at 1200°C. The fuel consists of a gas produced from green hydrogen and captured CO2, using solar heat. La Tribune de Genève Online News has reported that Synhelion’s thermochemical reactor further helps to capture CO2 emissions from clinker production. A study by the Swiss Federal Institute of Technology Lausanne indicated that this can halve the cost of carbon capture at cement plants, to below Euro85/t.
