US: Brimstone is negotiating a US$189m Federal award with the Department of Energy to finance the construction of a new decarbonised cement plant. This plant will produce up to 140,000t/yr of Ordinary Portland Cement and supplementary cementitious materials, reducing CO₂ emissions by 120,000t/yr.
Brimstone's process uses carbon-free calcium silicate rocks, reducing its CO₂ footprint. In July 2023, Brimstone's cement met ASTM C150 standards, confirming the effectiveness of its decarbonised process. The company is preparing to construct a pilot plant near Reno, Nevada.
