Rondo Energy, Siam Cement Group expand battery production capacity to 90GWh

Rondo Energy Inc (Rondo), the manufacturer of Rondo Heat Batteries on Monday (June 26) announced plans to expand the production capacity of Rondo Heat Battery storage at the Siam Cement Group (SCG) facility to 90GWh per year.

Rondo heat batteries store electric power as high-temperature heat in refractory brick, without the use of combustibles or critical minerals. Through Rando's battery technology by harnessing renewable energy we can get continuous zero-carbon industrial heat which can be made available for industrial use.

"SCG has been a phenomenal partner," said Rondo CEO John O'Donnell. "We found we had a common vision and uniquely complementary capabilities to bring this technology to world scale to address the greatest challenge of our times. With the technology now in commercial operation, Rondo's next milestone is creating the delivery capacity to meet the growing needs of projects worldwide."

SCG, through its subsidiary Siam Refractory Industry Co. (SRIC), produces refractory bricks of advanced quality and scale. By bringing their technology and capabilities together, the two companies will mass produce with a capacity of 2.4 GWh per year already online.

"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," said SCG's Executive Vice President, Thammasak Sethaudom.

"We also realized that we can leverage our 70 years of technical expertise in the refractory business and supply chain to support Rondo's mission to decarbonize industrial process heat, and we are happy to increase our capacity to meet market demand."

Rondo Energy was the Storage Innovations finalist of the Energy Storage Innovation Prize announced by the U.S. Department of Energy's Office of Electricity. 

Rando Energy's heat batteries are currently operating at an ethanol plant in California, serving an industrial customer with the world's highest temperature, and highest efficiency energy storage of any kind.
