Global: Policymakers, including those from the governments of Canada, the UAE and Thailand, are meeting cement industry CEOs in Bangkok to discuss how to further advance the decarbonisation of the cement industry. Thailand’s Minister of Industry, Pimphattra Wichaikul, opened the conference.

Wichaikul said “Thailand is one of the first countries in the word with a credible national roadmap for delivering on the cement industry’s net zero commitments. Key to success is innovation, cross-sectorial cooperation, strong leadership with clear targets and international collaboration to drive policy and implementation.”

Fernando González, CEO of Cemex and President of the GCCA, said “We have strong commitments and are already delivering the goal of building a more sustainable industry, and by working with governments, policymakers, built environment experts and other key players we have the opportunity to accelerate our progress in this important ‘decade to deliver’.”

The UN’s Industrial Development Organization (UNIDO) also unveiled a new package of investment, technical and other support, to help Thailand decarbonise its own cement industry.

Thailand: B.Grimm Power has partnered with Siam City Cement (SCCC) to establish a joint venture named ‘Insee B.Grimm Solar.’ This collaboration aims to develop a solar rooftop project and a ground-mounted solar photovoltaic (PV) project within SCCC’s plant located in Saraburi province.

This project is expected to contribute to Thailand’s clean energy goals by reducing reliance on fossil fuels and integrating renewable energy sources into industrial operations. Specific details regarding the project’s capacity and timeline are not yet available.

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 City Cement has appointed Ranjan Sachdeva as its Group CEO from the start of May 2024. He succeeded the previous CEO, Aidan Lynam, on an acting basis in January 2024. He will also continue to work as the Group Chief Financial Officer until a replacement is found.

Sachdeva has worked for Siam City Cement since 2017, first as the Group Head Internal Audit and Compliance and then as the Group Chief Financial Officer, from April 2023. Prior to this he worked in procurement and audit roles for Holcim in India. He has also spent time at Vedanta and Nestle during his career. He holds a bachelor of engineering from the Thapar Institute of Engineering & Technology and a master of business administration (MBA) degree from the University of Leicester, among other qualifications.

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.

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: Saraburi, which houses Thailand’s key cement plants, is expected to start converting waste to energy in a project led by the Thai Cement Manufacturers Association (TCMA). TCMA has developed a pilot project to create ‘ignitable waste pallets’, which will replace imported coal in cement production, according to TCMA chair Dr Chana Poomee. The process involves using waste from mining, cement plants and local communities to produce fuel, focusing on waste that cannot be reused or recycled.

Seven cement plants are located in the Tan Diao subdistrict due to its proximity to limestone mountains essential for cement production. The province is facing a growing waste management problem, owing to urbanisation and the expansion of agribusiness in the area. ‘Saraburi Sandbox’ project, a public-private-people partnership (PPP), seeks to address these issues.

Kittipong Promwong, president of the National Higher Education, Science, Research and Innovation Office, believes the Saraburi Sandbox is crucial to the government's commitment to lowering CO₂ emissions.

Thailand: Chair of the Thai Cement Manufacturers Association (TCMA), Dr Chana Poomee, announced the company’s new strategy, called 'TCMA Synergising the Actions toward Net Zero 2050'. This strategy aims to drive the cement industry towards clean energy transition, connect with global green funds and address climate change.

The vision involves four key missions for 2024-2026, including developing low-carbon cement, enhancing resource-efficient mining practices, building an integrated waste-to-value ecosystem, and transitioning to clean energy.

The TCMA also aims to reduce its CO₂ emissions by 6.9Mt/yr by 2030. Collaborations with various partners, including the Thailand Fellowship Cement Manufacturers and the Thai Bankers Association, are planned to leverage innovation and government policy support.

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.
