Spain: Molins has received permits from the Generalitat de Catalunya to begin operating an auxiliary hydrogen generation facility at its Sant Vicenç dels Horts cement plant in Barcelona.

The producer will install a hydrogen production module based on water electrolysis, using water from subway catchments. The system includes osmosis treatment to purify the water prior to splitting it into hydrogen and oxygen using renewable electricity. The hydrogen will be consumed directly as fuel in the clinker kiln, replacing part of the petcoke currently used to reduce CO₂ emissions.

Molins forecasts hydrogen consumption of 305t/yr and expects to cut CO₂ emissions by 3600t/yr. The company said the project supports its Sustainability Roadmap 2030, which targets a 20% reduction in emissions by 2030 compared to 2020.

Spain: A local cement manufacturer will integrate ‘green’ hydrogen into its production process using a 2MW Neptune II electrolyser from Uk-based supplier ITM Power, according to H2 View news. The electrolyser will supply hydrogen to be co-fired with natural gas in the cement kiln, expected to reduce CO₂ emissions. The method was previously demonstrated in 2021, when Hanson UK (now Heidelberg Materials) and MPA trialled hydrogen co-firing in cement production. It will be the first time that ITM has deployed the system in the cement industry.

UK: A consortium led by HydraB Group - including Hygen Energy, Ryze Power, HYCAP Group and Wrightbus -has submitted proposals to the UK government for the development of Project HySpeed. The project targets 1GW of green hydrogen production capacity by 2030. The €7.6bn project aims to develop a national network of hydrogen production hubs to fuel energy-intensive industries like steel, glass and cement production,via the gas grid.

Project HySpeed, which is also backed by a large private-sector coalition that includes Centrica (owner of British Gas), JCB, Johnson Matthey, Heidelberg Materials UK, ITM Power and National Gas, aims to cut CO2 emissions from heavy industry by 1Mt/yr.

Earlier in April 2025, the UK government shortlisted 27 electrolytic hydrogen projects to progress to the next stage of the Second Hydrogen Allocation Round (HAR2), during which the government expects to support up to 875MW. It previously allocated €2.23bn of funding for 11 large-scale green hydrogen projects under HAR1.

Spain: Holcim, IGNIS P2X and Exolum have launched Eco2fly, a project to convert industrial CO₂ emissions into sustainable aviation fuel at Holcim’s Villaluenga de la Sagra plant in Toledo. The facility will capture over 700,000t/yr of CO₂ from the plant’s cement production process and convert it into 100,000t/yr of sustainable aviation fuel using ‘green’ hydrogen. The remaining CO₂ will be stored in geological repositories. Over its first 10 years, the project will reportedly avoid more than 6.5Mt of CO₂ emissions.

UBE Mitsubishi Cement recently released an update on its commercial scale demonstration using ammonia as a fuel at its Ube plant. It is currently testing the use of ammonia in both the cement kiln and calciner at the site. It has set the aim of reaching a 30% coal substitution rate with ammonia in the cement kiln by the end of March 2025. It has described the project as a world first. Planned future work includes running ammonia combustion tests alongside post-consumer plastics.

The company announced the three-year project in mid-2023. Utilities company Chubu Electric Power has been working on it and UBE Corporation has been supplying the ammonia for the test. The scheme dates back to before Mitsubishi Materials and Ube Industries merged their cement businesses in 2022. Ube Industries previously took part in a government research project looking at the topic, running combustion tests and numerical analysis in small industrial furnaces.

Another ammonia research project in the cement sector was revealed in 2024 by Heidelberg Materials in the UK. The company was awarded just under €0.40m in funding by Innovate UK through its UK Research and Innovation (UKRI) fund, together with engineering consultants Stopford and Cranfield University. The 12-month feasibility study aimed to assess the use of ammonia as a hydrogen carrier and evaluate the most economical method of on-site ammonia cracking to generate hydrogen for use by clinker kilns. It also intended to investigate the various tiers of the UK's existing ammonia supply chain network for the suitable transportation, offloading and storage of ammonia.

The UK project explained that it was looking at ammonia as a hydrogen carrier due to its high volumetric energy density. This, potentially, makes ammonia easier and cheaper to store and transport than hydrogen. It pointed out that storing and transporting hydrogen is difficult and the chemical is expensive. It also noted that the volumetric energy density of ammonia is 45% higher than that of liquid hydrogen. The benefit of switching to a zero-carbon fuel was that it could cut CO₂ emissions by the cement and concrete sector in the UK by 16%.

The attraction of ammonia to the cement industry is similar to that of hydrogen. Both are versatile chemicals that can be produced and used in a variety of ways. The production processes and supply chains of both chemicals are linked. The Haber–Bosch process, for example, uses hydrogen to manufacture ammonia. It can also be cracked to release the hydrogen. When used as fuels neither release CO₂ emissions directly. This comes down to the method of production. Like hydrogen, there is a similar informal colour scheme indicating carbon intensity (Grey, Blue, Green and Turquoise). Despite the advantages listed above, the disadvantages of using ammonia include toxicity and NO_x emissions, as well as the fact that there is little experience of using ammonia as a fuel. The worldwide ammonia market was bigger by volume in 2023 with production of just under 200Mt compared to hydrogen production of just under 100Mt.

Back in Japan, the national government has been promoting the use of ammonia technology for the power generation sector. It added ammonia to the country’s national energy plan in the early 2020s following research on running power plants with a mixture of ammonia and coal. The ambition is to build up levels of ammonia co-firing at power plants, develop the necessary technology and grow supply chains. This, it is hoped, will broaden, diversify and decarbonise the domestic energy mix and pull together a new international market too. Unfortunately, this strategy has had criticism. One study by BloombergNEF in 2022 estimated, for example, that the electricity cost of Japan-based power stations switching to firing ammonia by 2050 would be more expensive than generation from renewables such as solar or wind.

This explains why the ammonia project by UBE Mitsubishi Cement is leading the way. The interest by a European cement company shows that others are thinking the same way too. Yet again, the potential decarbonisation solution for cement is likely to lead towards more complex industrial supply chains. The next steps to watch will be whether a cement plant in Japan actually starts to co-fire ammonia on a regular basis and if any more ammonia projects pop up elsewhere around the world.

Egypt: Arabian Cement Company (ACC) has signed a €25m loan agreement with the European Bank for Reconstruction and Development (EBRD). The loan will be used to assist the company’s decarbonisation efforts. It will finance the company’s alternative fuel capacity expansion and automation of its facilities. The company will also acquire and install a hydrogen injection system at its Ain Sokhna cement plant. This will reduce CO₂ emissions by 130,000t/yr.

CEO of Arabian Cement, Sergio Alcantarilla, said "This agreement with EBRD is a key milestone in ACC's sustainability journey, supporting our transition to cleaner technologies. The integration of the hydrogen injection at our Ain Sokhna plant will enhance operational efficiency and significantly reduce our carbon footprint."

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.
