Brimstone Company Profile

Background

Brimstone, founded in 2019 and headquartered in Oakland, California, is dedicated to transforming heavy industry by developing deeply decarbonized processes for producing essential materials such as portland cement, supplementary cementitious materials (SCM), and smelter-grade alumina. The company's mission is to mitigate the significant carbon emissions associated with traditional cement and alumina manufacturing, sectors responsible for approximately 8% of global CO₂ emissions.

Key Strategic Focus

Brimstone's strategic focus centers on:

Decarbonizing Cement Production: Utilizing a novel process that replaces limestone with carbon-free calcium silicate rock, eliminating process emissions while producing ASTM C150-compliant portland cement.

Co-Production of Industrial Materials: Simultaneously producing portland cement, SCM, and smelter-grade alumina from abundant, domestically sourced feedstocks, enhancing cost-effectiveness and sustainability.

Strengthening the U.S. Aluminum Supply Chain: Establishing the first new American source of alumina in over 50 years, reducing reliance on imports and bolstering national security.

Financials and Funding

Brimstone has secured significant funding to advance its initiatives:

Series A Funding: Raised $55 million in March 2022 from leading climate investors, including Breakthrough Energy Ventures, DCVC, Collaborative Fund, Fifth Wall, S2G Ventures, Amazon Climate Pledge, Acceler8, Gatemore, Impact Science Ventures, Osage University Partners, and SystemIQ.

Federal Investment: Selected for a $189 million federal investment in March 2024 through the Industrial Demonstrations Program to finance the construction of a first-of-its-kind decarbonized portland cement plant, projected to avoid 120,000 metric tons of CO₂ emissions annually.

Pipeline Development

Brimstone's key developments include:

Decarbonized Portland Cement: Achieved third-party verification that its cement meets ASTM C150 standards, ensuring compatibility with existing construction practices.

Alumina Production: Plans to establish a new alumina production facility, marking the first domestic source in over five decades, with significant implications for the U.S. aluminum industry.

Technological Platform and Innovation

Brimstone's proprietary technology involves:

Carbon-Free Feedstock Utilization: Employing calcium silicate rock instead of limestone, eliminating CO₂ emissions inherent in traditional cement production.

Co-Production Process: Simultaneously producing portland cement, SCM, and smelter-grade alumina from a single feedstock, enhancing efficiency and sustainability.
