News Siam Cement Group to upgrade Rondo heat battery unit in Thailand

Siam Cement Group to upgrade Rondo heat battery unit in Thailand

Written by Global Cement staff 04 July 2023

Thailand: US-based Rondo Energy and Siam Cement Group (SCG) plan to expand the production capacity of a heat battery storage unit at a SCG plant to 90GWh/yr. Once complete the site will reportedly have a production capacity larger than any current heat battery-supported manufacturing facility worldwide and will save up to 12Mt/yr of CO2. The SCG site already has a capacity of 2.4GWh/yr.

SCG’s executive vice president Thammasak Sethaudom said “Rondo offers an innovative solution to reduce the carbon emissions from industrial process heat used in factories worldwide. SCG can use Rondo’s technology to lower our own carbon emissions and SCG Cleanergy can partner with Rondo to help our customers cut emissions.” He added “We also realised that we can leverage our 70 years of technical expertise in the refractory business and supply chain.”

Rondo heat batteries consist of refractory bricks capable of storing renewable energy as heat. The heat energy can then be returned to an industrial process as hot air or steam. SCG invested in Rondo Energy in 2022.

This story was amended on 4 July 2023, after a previous version erroneously stated the location of the plant as Ukraine. Global Cement apologises for this error.
