Thailand: SCG Cleanergy and US-based Rondo Energy have launched a new 33MWh thermal battery integrated with SCG’s cement plant’s heat recovery system in Saraburi province. The system delivers 2.3MWth of continuous steam to the plant’s turbine, increasing output and enabling 24/7 electricity and process-heat supply. It also stores electrical energy as high-temperature heat in refractory materials and can reach 1500°C. CEO Eric Trusiewicz said the system was built in eight months. Rondo said that the installation is the world’s first commercial heat battery at a cement plant, and that it plans to scale further.
