Stardust Power

Stardust Power Inc. is a U.S.-based developer of battery-grade lithium carbonate, positioned to serve the electric vehicle and energy storage markets. Headquartered in Greenwich, Connecticut, the company is building a central lithium refinery in Muskogee, Oklahoma, designed for an annual production capacity of up to 50,000 metric tons. The Muskogee site is intended to consolidate refining operations in a single domestic facility, reducing reliance on overseas processing.

Stardust Power sources lithium from American brine deposits and is structured around a flexible feedstock model that can accept brine from multiple regions. This approach supports the build-out of a domestic supply chain for critical EV battery materials and aligns with broader U.S. policy efforts to onshore refining capacity for strategic minerals.

The company's output targets cathode producers and battery manufacturers that require high-purity lithium carbonate for use in lithium-ion cells. By focusing exclusively on midstream refining rather than upstream extraction or downstream cell production, Stardust Power occupies a specialized position in the lithium value chain. Its operations connect U.S. brine resources with the cathode and EV manufacturing base, situating the company within the broader transition toward domestically refined battery materials and electrified transportation infrastructure.
