A 33 MWh thermal battery integrated with a cement plant’s heat recovery system has begun operating in Thailand. The deployment was built by U.S. thermal-energy-storage startup Rondo Energy in partnership with SCG Cleanergy. Rondo says the installation is the “world’s first commercial heat-battery system at a cement manufacturing facility,” and the company has plans to scale deployments further.
“This project shows that powering industry with clean energy is not just possible—it’s economical and fast,” said Rondo CEO Eric Trusiewicz. He added that the system was built in just eight months.
Locally manufactured system delivers 24/7 clean energy
The heat battery is now delivering 2.3 MWth of continuous steam, charged by both the grid and a nearby floating solar farm. Integrated with the cement plant’s existing heat recovery system, the unit supplies superheated steam to the facility’s steam turbine. This increases turbine output and enables the plant to generate both process heat and round-the-clock electricity.
