What's Happening?
Cobalt Blue Holdings, in collaboration with Glomar Minerals, is advancing its Project Infinity, which aims to establish the first commercial polymetallic nodule refinery in the United States. The company has received 25 kilograms of Clarion-Clipperton
Zone nodules at its Broken Hill Technology Centre. This marks a significant step in demonstrating their technology at scale. The project plans to process 200,000 tonnes of polymetallic nodules and 7,500 tonnes of cobalt hydroxide annually. The refinery will produce high-purity manganese sulphate and cobalt sulphate for battery markets, along with nickel and copper metal. Four potential sites in Texas, North Carolina, and Louisiana have been shortlisted for the refinery, following discussions with state economic development offices and government representatives.
Why It's Important?
The development of a polymetallic nodule refinery in the U.S. is crucial for diversifying critical mineral supply chains, particularly for the battery market. As demand for electric vehicles and renewable energy storage solutions grows, securing a domestic supply of essential minerals like cobalt, manganese, and nickel becomes increasingly important. This project positions Cobalt Blue as a leader in critical minerals processing, potentially reducing U.S. reliance on foreign sources for these materials. The initiative also aligns with broader efforts to bolster the U.S. economy by creating jobs and fostering technological advancements in mineral processing.
What's Next?
Cobalt Blue will begin bench-scale testing and characterization of the nodules to define the scope of the upcoming Prefeasibility Study. This study will further detail the technical and economic feasibility of the refinery. The selection of the final site for the refinery will depend on the outcomes of these tests and ongoing discussions with state and federal stakeholders. The project is expected to attract attention from policymakers and industry leaders interested in strengthening the U.S. position in the global battery supply chain.
