UK: Heidelberg Materials UK has secured planning permission to build a carbon capture plant at its Padeswood cement works in north Wales. The facility will capture up to 800,000t/yr of CO₂ for storage via the HyNet North West pipeline under Liverpool Bay.

The project is expected to create around 50 new full-time jobs, and up to 500 additional jobs during construction. Once operational, the Padeswood facility will capture ‘almost all’ of the CO₂ produced at the cement works and enable the production of evoZero cement by 2029.

UK: Drax Power has entered a 20-year joint venture agreement with Power Minerals to build a new facility to process pulverised fuel ash into supplementary cementitious material (SCM) for cement.

The facility will be located adjacent to Drax Power site and will produce 400,000t/yr of SCM for use in lower-carbon cement. Power Minerals will construct, own and operate the plant. Drax will supply ash, power and water, as well as share profits from SCM sales. There is no capital investment required by Drax.

Operations will begin by the end of 2026. Drax expects the project to generate incremental adjusted earnings by interest, taxation, depreciation and amortisation (EBITDA) of €6m annually between 2027 and 2046.

UK: The University of Sheffield, the Sellafield power station, the Nuclear Decommissioning Authority and the UK National Nuclear Laboratory have launched a €1.2m research partnership to explore the use of limestone calcined clay cement (LC3) in nuclear waste encapsulation. The project will study how characteristics and amounts of calcined clays can produce cement encapsulants that support safe and reliable nuclear waste conditioning and disposal at Sellafield.

Head of the Sheffield research team Brant Walkley said “This partnership will enhance our overall programme of work focused on development of new cement technologies for the nuclear sector, and will enable our cross-sector team based at both the University of Sheffield and Sellafield to further strengthen its position as a global leader in cement science and engineering.”

UK: Cemex has announced the construction of a mortar plant in Swindon, Wiltshire as part of its strategy to supply more alternative and sustainable materials to growing urban centres. The Mexico-based group said the plant will begin operations in the second half of 2025.

The new plant will produce Cemex's Vertua low-carbon mortars, with a CO2 footprint at least 30% lower than that of standard mortars. It will also feature a drying system designed to minimise heat consumption and significantly reduce fossil fuel consumption throughout the production process.

"As part of our growth strategy, we make strategic acquisitions and build new plants in advanced markets," said Fernando A Gonzalez, Cemex's CEO. "This strategically-located plant will enhance our production capacity in the country, advance our decarbonisation goals and allow us to offer a better experience to our customers in the region."

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.

UK: Cimpor is expanding into the UK following a change in ownership in 2024 and new capital investment. Cimpor registered Cimpor UK Limited in April 2024 with an office in Cheadle and has invested €20-25m in a terminal at the port of Bristol. It plans to expand its product range in the UK in the coming years.

Cimpor Global chief technology officer Berkan Fidan said “With the ports and terminals we own and operate, we leverage our export globally, strengthening our supply chain and continuing to explore new market opportunities.”

UK: Union officials have raised concerns over 41 job losses at Tarmac’s Dunbar cement plant in East Lothian, which represents about a third of its workforce. The plant has been described as ‘critically important to the Scottish economy,’ according to The Scotsman newspaper. Trade union GMB Scotland has called on the Scottish government to intervene, warning that the cuts would harm local communities and Scotland’s manufacturing base. The 0.7Mt/yr plant has reportedly entered talks with workers over the potential job cuts, but questioned have been raised over whether production levels can be maintained after job losses.

GMB Scotland organiser Stephen McGhee said “This may be the first step in deindustrialising the site with work, skills and taxes going elsewhere. With the widespread use of concrete, this would be another blow to Scotland’s manufacturing base and workforce.”

UK: Breedon has replaced the Traylor primary gyratory crusher at its Hope Cement Works after 72 years of operation. According to a post on Facebook by Breedon, the original crusher had been in service since 1952, crushing over 110Mt of minerals during its 72-year lifespan. FLSmidth supplied the new 1250t/hr primary gyratory crusher, which was successfully commissioned in October 2024.
