Stardust Power has received an air-quality construction permit from the Oklahoma Department of Environmental Quality for its planned lithium carbonate refinery in Muskogee, Oklahoma. The permit completes the facility’s construction and commissioning approvals, reducing regulatory risk ahead of final investment and financing decisions.
From an electric vehicle (EV) supply-chain perspective, the project addresses a key upstream bottleneck: domestic production of battery-grade lithium carbonate.
The permitted refinery is designed to operate as a minor emissions source under state and federal regulations and incorporates closed-loop water processing with no industrial wastewater discharge. The permitting review covered emissions control technologies, monitoring systems, and compliance with applicable air quality standards.
Once operational, the facility is expected to produce up to 50,000 metric tons per year of battery-grade lithium carbonate, supporting North American lithium-ion battery manufacturing for EV and energy storage applications.
The project reflects broader efforts to localize critical materials processing as EV production scales in the US.
