Southeast Asia's First Industrial Heat Battery Begins Operation in Thailand

In a groundbreaking event that promises to transform the industrial energy landscape, Rondo Energy has launched Southeast Asia's first industrial heat battery at SCG's cement plant in Saraburi Province, Thailand. This project marks a significant stride towards sustainable energy solutions in the region, showcasing the potential of innovative technologies in achieving climate goals.

A Milestone in Clean Energy

On November 14, 2025, the ribbon-cutting ceremony celebrated not just the technology, but also the collaboration between Rondo Energy and SCG Cleanergy, a subsidiary of SCG focusing on renewable energy solutions. The newly operational heat battery is now generating an impressive 2.3MWth of continuous steam, harnessed from both the grid and an adjacent floating solar farm. This superheated steam is crucial for driving a steam turbine that produces clean electricity for cement production, marking a new era in industrial energy efficiency.

Eric Trusiewicz, CEO of Rondo, emphasized the significance of this achievement, stating, "Today, we are not just launching a product; we are advancing a new modular approach to heat battery technology. This is our first venture in Southeast Asia and the only system worldwide designed to provide high-pressure steam for electric power generation."

The Modular Heat Battery Design

The 33 MWh Rondo Heat Battery showcased at the event is built on a modular platform that allows for scalable solutions ranging from 33 MWh to over 1 GWh. This flexibility caters to various customer needs, from smaller installations for food and beverage sectors to larger systems serving extensive chemical plants and metal refineries.

Rondo’s modular design incorporates mass-manufactured heating elements, ensuring reliability and consistency across different deployment sizes, simplifying the installation, and accelerating project delivery.

Promoting Local Economies

One of the project's highlights is its local development approach. Rondo and SCG Cleanergy devised the heat battery entirely in Thailand, emphasizing the importance of forming robust local supply chains. By integrating local suppliers, the project not only boosts Thailand’s economy but also demonstrates how effective use of local resources can lead to efficient cost management.

The collaboration aims to develop further clean industrial heat projects powered by Rondo’s technology across Southeast Asia, signaling a commitment to sustainable development in the region.

A New Standard for Industrial Energy

The operational heat battery is pivotal as it integrates seamlessly with the cement plant's heat recovery system, driving the steam turbine in a unique way—none other currently does this worldwide. The ability of the heat battery to convert thermal energy into clean electricity showcases its potential to revolutionize how industries, such as textiles and food processing, utilize energy.

Trusiewicz pointed out the project's swiftness in execution, revealing, "It took just eight months to build this first-of-its-kind system, proving that transitioning to electric-powered industries is not only feasible but can happen rapidly."

Leading the Future of Clean Energy in Asia

As the demand for industrial decarbonization grows, Rondo and SCG are poised to scale their manufacturing and deployment efforts. Both companies are keen on establishing Thailand as a leading hub for clean heat manufacturing, aiming to inspire other regions to embrace similar technologies.

SCG Cleanergy CEO Attapong Sathitmanothum remarked, "This project signifies a turning point for Southeast Asian industry as we focus on providing clean energy solutions that align with our goals for Inclusive Green Growth."

With ambitions set towards achieving SCG's Net Zero 2050 aspirations, the partnership with Rondo marks a promising step toward sustainable and competitive industrial practices in the future.

In summary, Rondo Energy and SCG Cleanergy’s initiative in Southeast Asia not only introduces cutting-edge technology in heat storage and generation but also sets the stage for a cleaner, more sustainable industrial sector throughout the region.
