Thailand/Myanmar: Siam Cement Group (SCG) has suspended the operations of two plants in Myanmar and halted any expansion plans over the next two years amid ongoing economic decline and political instability. The economic situation in Myanmar has deteriorated since the outbreak of Covid-19 and was exacerbated by the 2021 military coup and continuing conflicts between the junta government and various ethnic groups, reports The Nation newspaper.

SCG's executive vice president, Thammasak Sethaudom, stated that the company has invested over US$240m in these facilities. He said "There is no hope of resuming operations anytime soon. Myanmar has another cement plant in the north, owned by a Chinese company and guarded by the Chinese military. SCG could not do that and we would not risk our employees’ lives."

Thailand: Siam Cement has reported its results for the first half of 2024. Sales stood at US$13.9bn, slightly down from US$14bn previously. Net income declined threefold to US$340m compared to US$1.36bn a year ago.

For the quarter ending 30 June 2024, the company recorded sales of US$3.5bn compared to US$3.45bn in June 2023, and a net income of US$102m compared to US$223m.

Thailand: Siam Cement Group has awarded JGC Corporation the pre-feasibility study for a carbon capture and utilisation (CCU) facility at a cement plant in Thailand. The study will determine the technology license, assess the required production capacity for CO₂ capture facilities and evaluate the economic feasibility of constructing a CCU facility, which will capture and convert CO₂ from SCG's cement plant emissions into new chemical products.

Vietnam: Siam Cement Group (SCG) has announced the launch of a new 20% reduced CO₂ cement in Vietnam. Việt Nam News has reported that SCG achieved the reduction through technical upgrades to its cement production, alternative fuels co-processing and waste heat recovery. The producer said the move is a response to growing demand for lower-carbon alternatives in the country’s cement market.

Deputy country director for Vietnam Tanakorn Theeramankong said "For the first time, SCG has introduced a new low carbon cement to the Vietnamese market, marking a significant step forward in our journey to achieve net-zero emissions. By pursuing advanced technologies to develop low carbon cement, we not only reduce our environmental impact but also set a new standard for Vietnam’s construction industry."

Thailand: Siam Cement Group (SCG) has begun construction of a commercial heat battery supplied by Rondo Energy at its cement plant in Saraburi Province. It will be the first heat battery in Southeast Asia and the first heat battery deployed at a cement plant, according to the company. The project is a collaboration between Rondo Energy and SCG Cleanergy, a wholly owned subsidiary of SCG. Rondo Heat Batteries capture intermittent electricity and store energy as high temperature heat in bricks, to deliver continuous industrial heat and power on demand. This installation will convert local solar power into continuous zero-carbon heat and power for cement production.

President of Rondo Energy, Eric Trusiewicz, said "Electrification of cement production requires a large-scale and low-cost energy storage solution, as renewables are not available 24/7 but cement production needs to be."

Thailand: Siam Cement Group (SCG) reported first-quarter sales of US$3.36bn in 2024, down by 3% year-on-year. The group partly attributed this to a decline in its cement volumes. Nonetheless, group earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 4% to US$341m. Special items in the group’s first-quarter 2023 results precipitated an 85% year-on-year decline in net income to US$65.5m from US$446m.

SCG recorded first-quarter CO₂ emissions of 5.99Mt, outstripping the Science-Based Targets Initiative (SBTi)’s recommendation of a 2.5% annual reduction. It relied on 47% renewable energy sources in its cement production.

Indonesia: Siam Cement Group (SCG) subsidiary PT Semen Jawa used 24,000t of alternative raw materials in its cement production during the first quarter of 2024. These circular materials included bottom ash, fly ash and slag. This corresponds to 3% of its total raw material usage. Meanwhile, the producer co-processed 15,000t of alternative fuel (AF) during the quarter, representing a 20% AF substitution rate.

SCG Indonesia director Warit Jintanawan said that the developments "Not only enhance production efficiency, but also significantly reduces our carbon footprint. This is a testament to SCG's commitment to supporting Indonesia's climate goals, aiming to reduce greenhouse gas emissions by 32%, aligned with Enhanced National Determined Contributions."

Thailand: Biochar Life and Siam Cement Group (SCG) have signed a Memorandum of Understanding to jointly develop biochar-infused cement and sustainable building materials. This collaboration aims to utilise biochar in the construction industry and reduce carbon emissions.

The partnership will begin with a pilot project at Chiang Mai University, focusing on constructing biochar-infused cement roads. Biochar Life will evaluate the scalability of biochar production to meet SCG's material requirements. Both companies will engage in research and development to optimise the production and application of biochar in construction, considering environmental benefits and carbon removal credit opportunities.

SCG also plans to extend Biochar Life’s smallholder farmer program, incorporating mobile industrial units and other technologies. This joint effort is directed towards incorporating carbon-negative biochar into building materials. This will lower construction-related carbon emissions, aid in atmospheric carbon sequestration, and improve the durability and performance of these materials.

Thailand: Siam Cement Group (SCG) has introduced a new low-carbon cement, contributing to Thailand's net-zero ambitions. According to the company, SCG is Thailand's first cement manufacturer to produce this eco-friendly cement, reducing CO₂ emissions to as low as 0.05t during production. The new cement reportedly matches or is stronger than traditional Portland cement. SCG achieved this by improving its manufacturing processes, using clean energy sources and waste heat utilisation, leading to a 38% decrease in energy consumption. The company also modified raw material ratios in order to further reduce emissions.

SCG's president of the cement and green solutions department, Surachai Nimlaor, said “Since cement production consumes a considerable amount of energy and emits CO₂ during the process, we decided to find out how we could reduce this impact." He continued “With the initial low-carbon cement formula, we have reduced emissions by 15 to 20%. Moving forward, our goal is to develop new formulas that can reduce carbon emissions by up to 50%.”

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.
