Southeast Asia’s first industrial heat battery has been launched in Thailand, marking a significant step toward decarbonizing industrial heat applications in the region and offering a blueprint for heavy industries worldwide.
Partnership for Sustainable Energy with Thailand heat battery
The new system is a groundbreaking collaboration between the US-based thermal storage company Rondo Energy and SCG Cleanergy, the clean energy subsidiary of the Siam Cement Group (SCG). This initiative provides a powerful clean energy solution for the cement industry, which is known for its high carbon emissions and intense energy requirements.
The 33 MWh Rondo Heat Battery (RHB) has been installed and is now operational at SCG’s cement plant in Saraburi Province, Thailand. It is ingeniously designed to capture and store intermittent renewable energy—primarily from a nearby solar farm and the grid—when it is abundant and low-cost. This energy is converted into high-temperature heat and stored within bricks made from specialized raw materials. On demand, the battery releases this heat to produce high-temperature steam, which powers a turbine for industrial electricity generation.
This technology provides a reliable, 24-hour source of zero-carbon energy, directly replacing the fossil fuels traditionally used in the cement production process. It showcases a practical application of the basics of solar panel manufacturing by creating a method to store the energy produced by solar installations for industrial use around the clock.
Cutting Carbon Emissions with the Thailand heat battery
The heat battery system is projected to cut carbon emissions by up to 85% compared to traditional fossil-fuel-based heating methods. By converting surplus renewable electricity into heat at temperatures up to 1,500 degrees Celsius, the system is versatile enough for the most demanding industrial applications.
This project is a cornerstone of a broader effort to position Thailand as a leader in renewable energy adoption in Southeast Asia. The country has set an ambitious target to increase its share of renewable energy in the national energy mix to 30% by 2036, supported by government policies that encourage investment through tax incentives and subsidies.
For homeowners and tenants in Germany, this development in Thailand is surprisingly relevant. Germany’s own “Energiewende” (energy transition) and “Wärmewende” (heat transition) face similar challenges, particularly in decarbonizing heavy industries like steel, chemicals, and glass. Technologies like the Rondo Heat Battery offer a viable pathway to replace natural gas with renewable heat, enhancing energy security and helping to stabilize industrial energy costs, which can ultimately impact consumer prices. The entire manufacturing process for many essential goods could become cleaner and more sustainable with such innovations.
Future Prospects for the Thailand heat battery
The successful launch of this heat battery is a major milestone in the region’s energy transition. It is expected to serve as a model for other industrial sectors in Thailand and across Southeast Asia. The technology’s potential extends well beyond cement to other high-temperature industries, such as steel and glass manufacturing, which are also seeking effective decarbonization strategies.
The modular design of these batteries, assembled using advanced manufacturing machines, allows for scalability and customization to meet the specific needs of different facilities. By enabling industries to store cheap renewable energy for later use, this technology not only reduces emissions but also offers significant economic advantages, helping to lower operational expenses in a way that is analogous to understanding the solar panel manufacturing plant cost breakdown for large-scale energy projects.
Thailand’s first industrial heat battery is a significant advancement in the global effort to reduce industrial carbon emissions. The project powerfully demonstrates the potential of thermal energy storage to provide a clean, efficient, and cost-effective solution for industrial heat. As the technology continues to evolve, it will play a crucial role in helping Thailand and other nations achieve their renewable energy and climate goals.
