UK: Cemex UK has announced that it will begin to use hydrogen on an industrial scale at its Rugby cement plant in Warwickshire. It will do so via HiiROC, a UK-based start-up that has received backing from Cemex Ventures. HiiROC produces carbon-neutral hydrogen using its proprietary Thermal Plasma Electrolysis (TPE) process, which requires just 20% of the electrical energy used in water electrolysis and captures carbon as a solid byproduct, avoiding CO₂ emissions. HiiROC’s modular solution can be deployed as single units to full-scale industrial plants. The hydrogen produced can be used as an alternative energy source to fuel clinker production processes, helping Cemex to achieve its decarbonisation goals.

"Our investment in this innovative project alongside HiiROC reinforces Cemex's commitment to transform the industry by working hand in hand with disruptive startups and new technologies," said Gonzalo Galindo, the head of Cemex Ventures. "Hydrogen as an alternative energy source has the ability to significantly reduce CO₂ emissions in our operations, aligning with our 2050 goal of becoming a net-zero CO₂ company and a leader in the industrial use of hydrogen."

Türkiye: Limak Çimento has carried out a month-long test on hydrogen fuel blends at its cement plant in Ankara. The company partnered with France-based Air Liquide for the supply of hydrogen, which was injected into the preheater tower. The pair previously used a 50% hydrogen blend during a test at Limak’s Polatli plant in June 2024, with ‘excellent results’, according to Hydrogen Insight.

Erkam Kocakerim, CEO of Limak Çimento, said "The purpose of this investment is to enable safe and effective use of hydrogen technologies in our cement kilns and to increase the rate of alternative fuel substitution. We aim to operate the kilns in our seven integrated cement plants with a low-carbon fuel mix between 2030 and 2035."

US: Colorado-based energy company NovoHydrogen plans to establish a hydrogen production facility at the Ash Grove Cement plant near Durkee, Oregon. Funded by the 2021 federal Bipartisan Infrastructure Act, the plant aims to start producing hydrogen fuel by 2028, according to CEO and founder Matt McMonagle. The hydrogen produced would be stored at the plant to be used to fuel trucks and other vehicles on-site, as well as potentially being used to power the plant. The construction of the plant will reportedly create 50 jobs.

Phillip Teintze, manager at the Durkee plant, said "The Ash Grove Cement Durkee plant is active in many opportunities to decarbonise our industry. Solutions for low carbon cement manufacturing are significantly challenging in terms of processes and expense. The Durkee plant is excited to see the development of NovoHydrogen’s efforts with the Department of Energy’s Pacific Northwest Hydrogen Hub. As hydrogen becomes environmentally and economically viable, we believe our facility could act as a distribution site, and potentially utilise hydrogen as a fuel to displace traditional fossil fuels.”

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.

Türkiye: Limak Çimento has received its inaugural delivery of green hydrogen from France-based Air Liquide at its Ankara cement plant. The partners say that the technology will reduce the plant’s CO₂ emissions by 180,000t/yr. ESMERK News has reported that the companies plan to commence a strategic collaboration for the development of green hydrogen ecosystems for the cement industry. Limak plans to implement net zero fuels in the kilns of all seven of its plants between 2035.

Global: Lhyfe and Fives have signed a memorandum of understanding to provide a decarbonised solution for the cement industry, covering everything from hydrogen production to combustion. This initiative is designed to accelerate the energy transition by enabling the use of hydrogen in process industries without the need to modify existing equipment.

Lhyfe will produce and supply green hydrogen, while Fives will offer optimised and safe solutions for its use in industrial combustion processes, including cement production.

Cemex announced last week that it will stop producing clinker at its Lloseta plant in Mallorca. Grinding activity at the site will continue, along with the shipment of bagged and bulk cement products. The company has framed the closure as part of its decarbonisation plans. The dismantling of the two preheater towers at the plant is scheduled to take place by the end of 2030. Cemex said that it will take this long to allow the cement plant to continue operating, as well as a neighbouring hydrogen unit and other nearby industrial units. The status of the Lloseta plant has been in question before. It was closed in early 2019 due to reduced cement demand and mounting European CO₂ emissions regulations. However, it reopened in 2021.

Readers may recall that Cemex España participated in the Power to Green Hydrogen Mallorca project. Land by the Lloseta cement plant was used to hold solar panels and a solar-powered hydrogen unit. Other partners in the project included energy suppliers Enagás and Redexis and renewable power and infrastructure company Acciona, among others. When the unit was commissioned in early 2022, it said it was the first solar power-to-green hydrogen plant in Spain. The link between Cemex and hydrogen is noteworthy given the cement company’s adoption of hydrogen injection as part of its alternative fuels strategy. Interestingly, Acciona planned to use a blockchain method to certify that hydrogen produced at the site was made using renewable energy sources. Heidelberg Materials also plans to use the same process to verify its evoZero brand of net-zero cement products in 2025. Another recent sustainability sector news story in Spain is the commissioning by Çimsa of a 7.2MW solar plant supporting its Buñol white cement plant in Valencia. The new installation is expected to supply about 18% of the plant’s energy needs.

On the corporate side of things, FCC revealed in mid-May 2024 that it was preparing to spin-off its cement and real estate subsidiaries into a new company called Inmocemento. The cement part of this is Spain-based Cementos Portland Valderrivas. The move is intended to bolster the values of the different parts of the business. The proposal will be put to FCC’s shareholders in late June 2024, with any resulting action taking place by the end of the year. The decision to separate FCC’s cement assets is reminiscent of the financial engineering Holcim has proposed with its US business. However, in this case the driver does not appear to be the disparity between the European and US stock markets.

Market data was also out this week from Oficemen, the Spanish cement association. Domestic cement consumption grew year-on-year in April 2024 but the year so far is looking weaker with consumption from January to April 2024 down by 4.5% year-on-year to 4.65Mt. This is below Oficemen’s forecast for 2024 where it expected a stagnant situation. However, there are eight more months to go. In 2023 cement consumption fell by 3% to 14.5Mt and exports declined by 7.5% to 5.2Mt. The association blamed continued underinvestment in both the public and private sectors due to economic instability since the Covid-19 pandemic. Graph 1 above shows the wider situation in the Spanish cement market over the last decade. The share of exports has declined and local consumption rebounded after 2020 but has declined since then.

These news stories provide a snapshot of what’s been happening in Spain recently in the cement sector. Oficemen’s prediction for 2024 is gloomy but local consumption has risen over the past 10 years. Exports have fallen but the cement association has started to spin the country’s decarbonsiation drive as a potential positive for the industry’s competitiveness generally. It’s hard to discern right now but there might be an advantage for an export-focused country that conforms to European standards in the future if it can hold onto its capacity. Admittedly, that’s a big if. This thinking along sustainability lines could be seen earlier in May 2024 when Cementos Molins Group rebranded itself as Molins. It described the rebranding as a bid to represent the wider range of construction products it manufactures and sells beyond cement. Oficemen has also pointed out that the local market has room for development given the relatively low cement consumption per capita in Spain compared to its peers. So, whatever happens next, there is likely to be room for improvement in the cement market.

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.”
