Brazil: Companhia Siderúrgica Nacional (CSN), Huaxin Cement and Votorantim Cimentos have all bid for InterCement’s Brazilian business, Valor Online News has reported. The source stated that Votorantim Cimentos is leading a consortium alongside Italy-based Buzzi and concrete producer Polimix Concreto, however the Brazilian cement market leader denied this, stating that its offer is ‘individual and independent.’ Both Votorantim Cimentos and CSN Cimentos are reportedly considering making initial public offerings (IPOs).

Votorantim Cimentos said “The company clarifies that it is not part of nor leads any consortium within the auction process. To date, its offer remains under evaluation by the respective seller and, therefore, no documents have been signed with any counterparty that generate an obligation or firm commitment for the acquisition of the assets that were the subject of the offer.”

India: UltraTech Cement has commissioned 1.8Mt/yr of new cement capacity at its Kotputli cement plant in Rajasthan. The expanded plant will help the producer to serve markets in Rajasthan and the National Capital Region. Projects Today News has reported that the expansion is part of a 22.6Mt/yr capacity growth drive, first announced in June 2022. The latest commissioning has raised UltraTech Cement’s all-India capacity by 1.3% to 137Mt/yr, and that in Rajasthan by 11% to 18.9Mt/yr.

Saudi Arabia: Sinoma Overseas Development completed start-up testing and hand-over of new grinding mills at Arabian Cement Company’s Rabigh cement on 21 February 2024. The supplier said that the delivery was in accordance with the terms of the original contract between its parent company, China National Building Material (CNBM), and the producer.

Sinoma Overseas Development attributed deviations from the project’s previously announced schedule to the need for discussions with CNBM about remaining project works, equipment operation plans, procurement schedules and acceptance tests. As provided for in the contract, the work will be subject to a 5% delay penalty.

Germany: Heidelberg Materials reported sales growth of 0.4% in 2023, to €21.2bn. The group saw its profits grow by 21%, from €1.72bn to €2.09bn. During the year, the company reduced its specific CO₂ emissions per tonne of cementitious material by 3% from 551kg to 534kg and lowered its clinker factor from 72% to 70%.

Chair Dominik von Achten said "In the 150th year of our company's history, we have once again shown that we can deal with change and crises. I am extremely proud of our teams around the world, who have remained firmly focused on our targets and have once again done an extraordinary job." He added "We are entering 2024 with optimism. Although the general economic conditions in the construction sector remain challenging, we anticipate growth in revenue and earnings also in the current year. Our shareholders are benefitting from this growth thanks to the progressive dividend and the new, comprehensive share buyback programme.”

Argentina: Camargo Correa Group’s auctioneer JP Morgan will receive offers from bidders for Loma Negra later in February 2024. The La Nación newspaper has reported that Loma Negra may attract a price of over US$700m. Private investors Marcelo Mindlin and Daniel Sielecki will bid together, against anticipated corporate bidders from Brazil and China. Mindlin and Sielecki are joint owners of utilities provider Transportadora Gas del Sur.

Colombia: Cementos Argos recorded a 30% year-on-year rise in its earnings before interest, taxation, depreciation and amortisation (EBITDA) to US$620m in 2023. This came despite a 3% drop in the producer’s cement sales, to 15.7Mt. Its profit rose by 83% to US$74m. The producer attributed the growth to favourable price dynamics, cost efficiencies and productivity improvements.

Cementos Argos had an installed cement capacity of 24Mt/yr at the end of 2023.

India: JK Cement Ltd has completed the acquisition of a 100% stake in Toshali Cements. The parties concluded their agreement in June 2023, at which time the value of the deal was reportedly US$19m.

Toshali Cements operates a 200,000t/yr cement plant and a 435,000t/yr grinding plant, both in Odisha.

US: Eagle Materials has outlined its climate change mitigation successes in its 2023 Sustainability Report. During 2023, the company increased its production of blended cement products, including Portland Limestone Cement (PLC). It commenced a major CO2 reduction study with the US Department of Energy, and established a Greenhouse Gas Reduction Team to explore new clean technologies. Eagle Materials says that it is currently working to increase the use of alternative fuels at three of its cement plants.

Valentine’s Day last week included some ‘hot’ news for the cement sector with the announcement that Electrified Thermal Solutions is preparing to build the first commercial-scale pilot of its Joule Hive thermal battery (JHTB) in San Antonio, Texas. The company is working with the Southwest Research Institute on the project along with Buzzi Unicem USA, 3M and Amy’s Kitchen as industrial partners. Advisors include Imerys. The project update follows the award of a US$5m grant from the US Department of Energy (DOE) in late January 2024.

The funding description from the DOE’s Industrial Efficiency & Decarbonization Office reports that the end goal is to “turn intermittent renewable electricity into constant industrial grade heat” that can replace fossil fuel usage. Electrified Thermal Solutions aims to test its JHTB thermal energy storage system, which uses electrically conductive refractory bricks, to convert and store electricity as heat at temperatures higher than 1700°C. The JHTB power ranges between 1 - 200MW of thermal output, with duration up to tens of hours, enabling ‘very affordable’ high temperature energy storage and on-demand heat. Notably, it can charge and discharge simultaneously, allowing a continuous heat supply.

Electrified Thermal Solutions is not alone in targeting the cement sector. As Global Cement Weekly has covered previously energy storage is a growing topic of interest with a few large-scale electrical battery units running at cement plants in Pakistan and Taiwan. The other big name in thermal batteries for cement production is Rondo Energy. Both Electrified Thermal Solutions and Rondo Energy are using modular three-dimensional arrays of refractory bricks to store thermal energy and then release it, although they are likely to have key proprietary differences. However, Rondo Energy appears to be further along the industrial adoption process so far. Titan Cement and Siam Cement Group (SCG) invested in Rondo Energy in 2022. Then in July 2023 SCG and Rondo Energy said that they were planning to expand the production capacity of a heat battery storage unit at an SCG plant from 2.4 GWh/yr in mid-2023 to 90GWh/yr. For more information on Rondo Energy read the feature by CEO John O’Donnell in the January 2023 issue of Global Cement Magazine.

The reason that this matters, as partly explained above, is that fossil fuels contribute about one third of the CO₂ emissions created by heating up the kiln in cement production to make clinker. This is dropping globally due to the uptake of alternative fuels, but burning alternative fuels emits gross CO₂, however you account for the emissions. Mass adoption of thermal batteries by the sector could potentially cut out this double-accounting and reduce that third down to the carbon footprint of the refractory bricks used. This would then create knock-on issues concerning what to do with the waste streams instead but that is not a problem for the cement sector. These are worries for another day, as we first need to see how thermal batteries work at scale at a cement plant.

A recent feature in the Economist considered whether the mass adoption of electrical power from renewable sources might be an increasingly viable path to decarbonising industry. Geopolitics, faster-than-expected growth in renewables and new technology are all doing their bit to make this possible. As with so much of the carbon agenda it may alter the very concept of the traditional cement production line or at least the speed of change. Just imagine how a future cement plant might look, decked out with a electrical micro-grid, a heat battery, an oxy-fuel kiln, a carbon capture unit and either a chemical plant or gas pipeline junction. Will it happen? Who knows… but it is an exciting time for the cement sector.
