Cemex highlighted its Clyngas project at its Alicante cement plant in Spain this week. The project will produce synthesis gas (syngas) from different types of waste for direct injection into the burner at the plant during the combustion process. It is being run in conjunction with Waste to Energy Advanced Solutions (WTEnergy), a company that Cemex invested in at the end of 2022. It is also receiving Euro4.4m in funding from the European Commission (EC) as part of its innovation fund for small scale projects. The initiative estimates that it will save over 400,000t of equivalent CO₂ during the first 10 years of the project's life by replacing petroleum coke with syngas.

Clyngas is another example of Cemex’s innovation with alternative fuels for cement and lime. It follows on from the group’s work with hydrogen injection into cement kilns. As presented at the 15th Global CemFuels Conference 2022 it has been using hydrogen in low volumes as a combustion enhancer in more than 20 plants worldwide. However, it was also looking into using hydrogen more directly as a fuel and as a feedstock for other alternative fuels. WTEnergy’s gasification process could potentially link up to this as it converts waste streams such as wood chips, agricultural waste, refuse derived fuel (RDF), solid recovered fuel (SRF), dry sewage sludge, meat and bone meal, poultry litter and plastics into syngas. WTEnergy then proposes that its gasification process and/or the syngas can be used for power generation and thermal applications. In the case of the Clyngas project it will be the latter, as the gasification process will be used to boost the burnability characteristics of RDF with a high biomass content. One part of this to note is that the syngas can potentially be used to manufacture hydrogen. This would be a useful capability for a cement company, for example, that was already using alternative fuels and was now considering further decarbonisation by switching to using hydrogen.

A few other cement companies have been looking at synthetic fuels too, but this has generally been as a by-product of carbon capture and utilisation. This week Lafarge France, for example, said it had signed a memorandum of understanding with Axens, EDF and IFP Energies Nouvelles for a synthetic fuel production trial. Its plan is to build a unit that will produce synthetic kerosene using captured CO₂ from a carbon capture installation at Lafarge France's Saint-Pierre-La-Cour cement plant. The kerosene will then be sold to airlines. Other examples of cement companies looking at using captured CO₂ to manufacture synthetic fuels include Finnsementti’s pre-engineering study with Aker Carbon Capture to consider producing methanol as a fuel for transport, Holcim’s and TotalEnergies’ various plans of what to do with the CO₂ captured from the-to-be upgraded Obourg cement plant and Cemex Deutschland’s ambitions for its Rüdersdorf plant.

As can be seen above there are different types of synthetic fuels and cement companies are at the research and pilot stages. Although there isn’t a commonly accepted definition of what a synthetic fuel is, the general meaning is that of a fuel made from feedstock using a chemical reaction as opposed to, say, a refining process. The wide variety of potential synthetic fuels puts the confusion over the different types of hydrogen into perspective. However, this may be a problem for a later date if usage by cement companies becomes more serious.

What is a problem, though, has been the EC’s planned legislation to phase out the use of industrial CO₂ in synthetic fuels by 2041. Cembureau, the European cement industry association, warned in late 2022 of the issues this would pose for industries trying to find a way to utilise their CO₂ emissions where storage was too difficult or expensive. Its view was that while synthetic fuels using industrial CO₂ are not fully net-zero, as the captured CO₂ is later released into the atmosphere, it is a necessary short to medium term step for sectors trying to make the transition. Companies trying to build industrial-scale chemical plants for synthetic fuels need running periods of 20 to 30 years to achieve payback. As of March 2023 Cembureau was still concerned about the implication of proposed regulations, specifically with regards to the proposed criteria for which synthetic fuels could be used, based on their greenhouse gas emissions savings (at least 70% compared to the regular fuels being replaced). It directly linked this to synthetic fuels projects being launched by the cement sector that might be adversely affected by the new rules. The EC published the legislation in late June 2023 and it is set to become legal in mid-July 2023.

Using synthetic fuels either as a fuel or a by-product from cement production is an area of interest currently with the projects detailed above and others in progress. One vision for their use in Europe, at least, is that they might offer a route for carbon capture for cement plants without access to the logistic networks necessary for sequestration. Whether they find a place in cement manufacture either on a transitional basis or over a longer term should become clearer over the coming decade. Yet the EC’s new rules are likely to slow this process down as at least some of the planned pilots may become unviable in Europe. Other jurisdictions around the world take note.

Belgium: Cembureau, the European Cement Association, has elected Ken McKnight as its president and Jon Morrish as vice-president. McKnight, a member of the CRH executive committee, succeeds Isidoro Miranda in the role. Morrish is the chief executive officer for Western & Southern Europe of Heidelberg Materials.

Ukraine: Buzzi has agreed to sell its business in Ukraine to Ireland-based CRH for US$109m. The assets additionally include Buzzi’s Slovakian ready-mix concrete business. The Ukrainian business is comprised of the 2Mt/yr Volyn cement plant and 1Mt/yr Nikolajev cement plants, as well as ready-mix concrete operations in Kiev, Nikolajev and Odessa.

Italy-based Buzzi retains its operations in Russia, including the 3.6Mt/yr Suchoi Log cement plant in Irkutsk Oblast and the 700,000t/yr Korkino cement plant in Chelyabinsk Oblast.

Ireland: Ecocem has appointed Jaouad Nadah as its Innovation Project Manager. He will be responsible for the coordination of the company’s ACT technology as it scales up development. This will include supporting a range of partnerships under development by Ecocem across Europe and beyond. Nadah previously worked for CRH-subsidiary Eqiom and Holcim, with a focus on innovation in the low carbon cement market. Ecocem launched ACT in late 2022. It says it is an alternative materials-based cement ingredient capable of reducing the CO₂ emissions of cement production by up to 70%.

US: Ash Grove Cement has won funding for a US$15.2m front-end engineering design (FEED) study for a carbon capture installation at its 2Mt/yr Foreman cement plant in Arkansas. Parent company CRH said that the study will run for 24 months from its date of commencement. The project team also includes consultancy and research firms Advanced Resources International and Crescent Resource Information, as well as non-profit interstate policy organisation Southern States Energy Board. Equipment suppliers will include France-based industrial gases company Air Liquide and energy company Sargent & Lundy, while electricity provider Talos will participate as an energy sector stakeholder.

The Foreman cement plant carbon capture FEED study is one of eight projects selected by the US Department of Energy to receive part of a US$189m funding pot for carbon capture demonstrations across US industry.

Ireland/US: Shareholders have approved Ireland-based CRH's board recommendation to transition to a US primary listing on the New York Stock Exchange. The company says that it will effect its transition on or around 25 September 2023. This will entail delisting shares from Ireland's Euronext Dublin, while retaining a standard listing on the UK's London Stock Exchange (LSE).

CRH derived 75% of earnings from North America in 2022. It expects the US market to be a key driver of future growth due to the country's growing populace and construction needs.

CEO Albert Manifold said "We are pleased to see such strong shareholder support for the listing transition, as it marks an important milestone in our development and will enable CRH to fully participate in the significant growth opportunities that lie ahead.”

Finland: Finnsementti is carrying out upgrades to its two integrated cement plants as part of its sustainability targets to 2030. The subsidiary of Ireland-based CRH is installing new main burner equipment at its Lappeenranta plant with completion scheduled for mid-2023. The project is intended to allow the plant to increase its use of alternative fuels. The company’s Parainen plant is replacing its satellite coolers with a grate cooler with completion scheduled for the spring of 2024. This work is expected to decrease the plant’s emissions by 10%. Overall the group is preparing to decrease its CO₂ emissions by 30% by 2030 compared to 2021 levels.

UK: Aggregate Industries, Breedon, Lhoist and Tarmac have announced the launch of the Peak Cluster, a carbon capture and storage cluster of cement and lime plants. The partners aim to eliminate 3Mt/yr of emissions from operations across their plants in Cheshire, Derbyshire and Staffordshire by capturing 100% of their CO₂ emissions. Progressive Energy will oversee the capture and transportation of CO₂ from the plants for storage below the Irish Sea. Possible storage partners for the cluster are Liverpool Bay CCS or the upcoming Morecambe Net Zero storage project. When operational, the Peak Cluster will eliminate 40% of emissions from UK cement and lime production. Participating cement plants are Aggregate Industries' 1Mt/yr Cauldon cement plant in Staffordshire, Breedon's 1.5Mt/yr Hope plant in Derbyshire and Tarmac's 0.8Mt/yr Tunstead plant in Derbyshire.

Mineral Products Association (MPA) energy and climate change director Diana Casey said “The launch of the Peak Cluster is an exciting and vital step forward in the journey of the cement and lime sectors towards net zero. The region is a historic heartland for cement and lime production providing highly skilled jobs for local communities, and a secure supply of essential materials to the UK economy." She concluded "The UK Concrete and Cement Industry Roadmap to Beyond Net Zero highlighted the importance of carbon capture for the decarbonisation of the cement and concrete supply chain, and the Peak Cluster is an essential part of that transition. This launch demonstrates the commitment of cement and lime producers to transition to net zero to secure the future of these important industries, and the vital products they produce, in a net zero world.”

Ireland/US: Albert Manifold, the chief executive officer of CRH, has described the company as a ‘de facto’ American company at it its annual general meeting. "This is a golden age of construction in the US," said Manifold, according to the Irish Times newspaper. He added that moving the group's main stock market listing to the US made it "more of an American company, which de facto we actually are". He also noted comments by US president Joe Biden in February 2023 that the country was planning “to buy American” as part of its infrastructure spending. North America accounted for 75% of the group’s earnings before interest, taxation, depreciation and amortisation (EBITDA) in 2022 compared to around a half in the early 2010s.

CRH said in March 2023 that it was preparing to move its primary listing of shares to a US-based stock exchange.

Ireland: CRH has reported a ‘positive’ start to 2023, with first quarter sales and earnings before interest, tax, depreciation and amortisation (EBITDA) ahead of its own expectations.

In a trading update chief executive officer Albert Manifold said “We had a positive start to the year in a seasonally quiet trading period. While some adverse weather conditions were experienced in the first quarter, sales and EBITDA were ahead, underpinned by the continued execution of our integrated solutions strategy and further commercial progress across our markets.”

In its Americas Materials Solutions business unit, CRH’s sales were 10% ahead of the first quarter of 2022, driven by robust pricing which more than offset the impact of unfavourable weather on activity levels in certain markets during this seasonally less significant quarter.

In Europe, like-for-like sales were 6% ahead of the first quarter of 2022 due to strong pricing momentum across all products and regions. Activity levels were impacted by less favourable weather conditions compared to the same period in 2022. Unfavourable currency exchange effects resulted in total sales being 1% behind 2022.

Manifold added, “Looking ahead, despite some ongoing macroeconomic uncertainties and an inflationary cost environment, we expect first-half sales, EBITDA and margin to be ahead of the prior year period.”
