Brimstone Commercial, LLC (BRIMSTONE) will construct and operate a new plant to commercialize a deeply decarbonized process for making ordinary Portland cement (OPC) and co-products, including supplementary cementitious materials (SCM) and smelter-grade alumina (SGA).

Brimstone will develop a transformative technology that applies a chemical-based process for making cement that eliminates process carbon dioxide (CO2) emissions associated with limestone processing.

The process also includes the production of SCM from siliceous residues to reduce emissions associated with concrete production and has the ability to incorporate direct air capture of atmospheric CO2 from magnesium-bearing waste residue.

This project will produce OPC and SCMs from carbon-free calcium silicate rock using a closed acid beneficiation cycle.

The new plant’s success, by demonstrating a pathway for achieving positive unit economics for Brimstone’s decarbonized cement production process, will de-risk the business model and support net-zero goals while increasing supply resiliency in the cement and aluminum industries.

This project plans to provide tangible benefits to the community by creating up to 100 family-sustaining operations jobs with comprehensive benefits, engaging with labor unions and supporting the use of negotiated agreements for the construction and operation of the facility.

This project will establish early two-way engagement with community members through a community advisory council, develop a local workforce development program, and ensure equitable access to benefits through partnerships with minority serving institutions and businesses majority-owned or controlled by underrepresented persons or groups of underrepresented persons.

THE U.S. DEPARTMENT OF ENERGY (DOE) RELEASED THIS FUNDING OPPORTUNITY ANNOUNCEMENT (FOA) TO SOLICIT APPLICATIONS IN ACCORDANCE WITH THE INFRASTRUCTURE INVESTMENT AND JOBS ACT (IIJA), ALSO KNOWN AS THE BIPARTISAN INFRASTRUCTURE LAW (BIL), AND THE INFLATION REDUCTION ACT OF 2022 (IRA). WHEN COMBINED WITH PRIVATE SECTOR COST SHARE, THIS FOA REPRESENTS A MORE THAN $12 BILLION OPPORTUNITY TO CATALYZE HIGH-IMPACT, LARGE-SCALE, TRANSFORMATIONAL ADVANCED INDUSTRIAL FACILITIES TO SIGNIFICANTLY REDUCE GREENHOUSE GAS (GHG) EMISSIONS IN ENERGY-INTENSIVE INDUSTRIAL SUBSECTORS. U.S. INDUSTRY IS A BACKBONE OF THE NATION’S ECONOMY, PRODUCING THE GOODS CRITICAL TO EVERYDAY LIFE, EMPLOYING MILLIONS OF AMERICANS IN HIGH-QUALITY JOBS, AND PROVIDING AN ECONOMIC ANCHOR FOR THOUSANDS OF COMMUNITIES. YET THE ENERGY- AND CARBON-INTENSITY OF THE SECTOR, WHICH CONTRIBUTES NEARLY ONE THIRD OF THE NATION’S PRIMARY ENERGY-RELATED CARBON DIOXIDE EMISSIONS, POSES A SIGNIFICANT CHALLENGE AS THE ECONOMY TRANSITIONS TOWARDS NET-ZERO. THIS FOA OFFERED A CRITICAL OPPORTUNITY TO SOLIDIFY A “FIRST-MOVER” ADVANTAGE FOR U.S. INDUSTRY, BOLSTERING ITS COMPETITIVENESS GLOBALLY FOR DECADES INTO THE FUTURE. ACTIVITIES FUNDED UNDER THIS FOA ARE FURTHER EXPECTED TO CREATE GOOD-PAYING JOBS FOR AMERICAN WORKERS, OFFER OPPORTUNITIES FOR BROADLY SHARED PROSPERITY IN COMMUNITIES, AND ENABLE A CLEAN, MORE EQUITABLE FUTURE FOR ALL AMERICANS. DEMONSTRATING THE TECHNICAL AND COMMERCIAL VIABILITY OF INDUSTRIAL DECARBONIZATION APPROACHES WILL PROMOTE WIDESPREAD TECHNOLOGY IMPLEMENTATION AND DRIVE A U.S. EDGE IN LOW- AND NET-ZERO CARBON MANUFACTURING WHILE HELPING TO SUBSTANTIATE A MARKET FOR LOW-CARBON PRODUCTS.
