Brimstone Advances Oklahoma Plans to Build First New U.S. Alumina Plant in 50+ Years
Brimstone, a U.S. leader in industrial innovation, announced it has signed a letter of intent with Oklahoma’s Dolese Bros. Co., to supply materials for its planned Rock Refinery—a commercial-scale plant producing portland cement, supplementary cementitious materials (SCM), and smelter grade alumina, the essential material for producing aluminum. Brimstone selected Dolese Bros. Co. following a competitive selection process that evaluated over 23,000 quarries across the United States.
Industrial Breakthrough: Brimstone to Produce Alumina, Bolstering U.S. Aluminum Supply Chain
Brimstone, a U.S. leader in industrial innovation, announced today that its deeply decarbonized cement manufacturing process will also produce smelter grade alumina—marking a major industrial milestone in the United States with direct implications for national security, domestic supply chains, and the economy. The Brimstone plant could represent the first new, domestic source of smelter grade alumina in a generation, entering a market currently led by China.
Industrial Demonstrations Program Selects Brimstone for Transformational $189 Million Federal Investment to Decarbonize Cement Industry
The Department of Energy (DOE) Office of Clean Energy Demonstrations (OCED) today announced that Brimstone, a leader in industrial decarbonization, was selected to negotiate a $189 million federal award to finance the construction of the first commercial-scale plant deploying Brimstone's deeply decarbonized process for producing cement.
Climate Breakthrough: Brimstone’s Decarbonized Portland Cement First to Meet Essential Building Industry Standard, Unlocking the Potential of Net-Zero Construction
Brimstone, a leader in industrial decarbonization, has received third-party certification that its cement meets or exceeds ASTM C150 standards for ordinary portland cement, becoming the first ultra-low carbon, carbon-neutral or carbon-negative cement to meet this critical and universally accepted industry requirement. This achievement validates that the cement Brimstone produces is ordinary portland cement, the type of cement used in virtually all construction today.
Brimstone to Produce the World’s First Carbon-Negative Portland Cement
Brimstone makes Ordinary Portland Cement, chemically and physically identical to conventionally manufactured cement, but without releasing CO2. At scale, Brimstone’s breakthrough will produce cement at or below market prices, solving the problems of both emissions and scarcity of raw materials, and without increasing cost or risk for customers. At scale, Brimstone’s process will be able to supply organizations and governments that want to construct new buildings or replace aging infrastructure but want to use tried and true building materials at an affordable price while also sequestering carbon.
