U.S. industrial innovator is in Oklahoma meeting with local and state officials, potential business partners as it homes in on the site for its first-of-a-kind plant
Advancing several key policy priorities for the Trump Administration, Brimstone's commercial-scale facility will use U.S.-mined rocks to produce cement and alumina, clearing a "mine-to-metal" path for U.S. aluminum production, onshoring the U.S. critical mineral supply chain, and creating jobs
OKLAHOMA CITY, Oklahoma — Brimstone, a U.S. leader in industrial innovation, met with state and local officials in Oklahoma this week as the company nears a siting decision for its first-of-a-kind plant. Brimstone’s plant would represent the first new, domestic source of alumina in a generation—a critical step in onshoring U.S. manufacturing and clearing a "mine to metal" pathway for domestic aluminum production.
"As part of a comprehensive review of potential U.S. locations, we are excited by the potential of making Oklahoma home to our commercial-scale production facility," said Cody Finke, co-founder and CEO of Brimstone. "Oklahoma checks so many of our boxes – with great potential partners, strong logistical resources, and an excellent business environment. As Brimstone enters the final phases of our process, we look forward to exploring potential construction sites and meeting with state and local leaders about the job creation, economic growth, and value that Brimstone will bring both locally and nationally."
Brimstone and the U.S. Department of Energy Office of Clean Energy Demonstrations finalized negotiations earlier this year for an award of up to $189 million, and a total project investment of up to $378 million, for its commercial demonstration plant. The plant will co-produce smelter grade alumina alongside two other co-products: portland cement and supplementary cementitious materials (SCM), another concrete ingredient.
As the essential feedstock in aluminum—a critical material (see, e.g., 2023 Final Critical Materials List) and the world's second-most consumed metal—alumina is vital to defense, aerospace, transportation, construction, technology, consumer goods, and clean energy industries. China currently dominates both the alumina and aluminum markets, while the U.S. is home to just one operational alumina refinery today. As the first domestic source of smelter-grade alumina in more than 50 years, Brimstone's plant clears a pathway to secure the entire U.S. aluminum supply chain, from mine to end metal, achieving a key U.S. policy priority.
Unlike conventional alumina production, which relies on bauxite—an ore found in certain tropical and subtropical regions overseas—Brimstone produces alumina from feed rocks that are highly abundant across the U.S. The widespread availability of Brimstone's rocks reduces the dependence of the U.S. alumina industry on imported bauxite, unlocking the ability to produce alumina efficiently and sustainably, virtually anywhere.
The company is actively engaging with potential customers and partners about its cement, SCM, and alumina. Brimstone is hiring across departments. See open roles and apply here.
