Stardust Power is developing a $1.2 billion lithium refinery on a 66-acre site in Muskogee County, Oklahoma. The facility is planned in phases, with public materials targeting roughly 25,000 tonnes per year in Phase 1 and about 50,000 tonnes per year at full build-out to produce battery-grade lithium products for domestic markets.
Key project milestones include a groundbreaking ceremony held on January 22, 2025, followed by the start of initial on-site construction activities. By May 5, 2025, Stardust Power reported progress on early commercial and infrastructure agreements, including a preliminary off-take engagement with Sumitomo for part of its initial lithium output and a power infrastructure agreement with Oklahoma Gas & Electric (OG&E). Under this arrangement, OG&E will design and build the electrical infrastructure needed to supply up to 40 megawatts (MW) of power to the facility.
In December 2024, the company purchased a 66-acre property near the Port of Muskogee following a thorough environmental assessment in 2023 that confirmed the site was viable for the refinery. This location presents multiple construction and operational positives: proximity to the largest inland waterway system in the country, good road and rail access, and an oil and gas-experienced labor force.
The site also has room for future growth, as it is adjacent to a 40-acre plot in which Stardust Power has a right of first refusal.
According to Stardust Power’s CEO, Roshan Pujari, the refinery will help develop better security and supply chains within the country as it is the largest in the U.S. “By returning critical mineral manufacturing to the U.S., we’re helping to strengthen America’s energy leadership. We are excited to start construction now that the land and permits are secured,” he said.
Lieutenant Governor Pinnell emphasized, “The start of this lithium refinery in Muskogee is a big step for Oklahoma, continuing to strengthen both our mineral supply chains and national security.”
Construction Phases
Construction will be done in two phases. Phase one will include a production line with the capacity for 25,000 tonnes annually, while the second will add another line and raise total capacity to 50,000 tonnes.
Once complete, the refinery will create hundreds of jobs in engineering, manufacturing, and operations. The construction phase is expected to generate many more job opportunities in construction and support services.
The refinery is part of a broader wave of U.S. projects aimed at strengthening domestic lithium production and refining capacity. In Nevada, American Battery Technology Company is advancing its Tonopah Flats Lithium Project, which recently cleared key federal environmental studies — another sign of progress toward a fully domestic battery materials supply chain.
