The U.S. Department of Energy Office of Clean Energy Demonstrations (OCED) has named four portland cement producers and two alternative binder start-ups as candidates for $1.6 billion in funds steered to projects lowering the carbon footprint of finished concrete. Heidelberg Materials and National Cement Company of California lead the way with their respective projects, Mitchell Cement Plant Decarbonization and Lebec Net Zero Cement Plant, each eligible for $500 million awards pending negotiations with OCED officials. The former project entails an ambitious carbon capture, storage and use (CCUS) facility planned for Heidelberg Materials’ Mitchell, Ind. cement plant. The National Cement undertaking combines CCUS infrastructure plus limestone calcined clay cement (LC3) production ramp up at the producer’s mill above Los Angeles.
Roanoke Cement Co. and Summit Materials Inc. are likewise eyeing LC3 capacity through their respective projects: Limestone Calcined Clay Cement Production, with a potential $61.7 award, and Low-Carbon Calcined Clay Cement Demonstration, with a potential $215.6 million award. The other two Cement and Concrete projects under the OCED Industrial Demonstrations Program, Deeply Decarbonized Cement and First Commercial Electrochemical Cement Manufacturing, involve Brimstone Energy Inc. and Sublime Systems Inc., with potential awards of $189 million and $86.9 million.
