SuperCritical Materials Lands DOE Patent, Advancing Uranium Extraction for Sustainable Energy

**SuperCritical Materials Lands DOE Patent, Advancing Uranium Extraction for Sustainable Energy**

*Introduction*
SuperCritical Materials announced on November 2 that it has secured a U.S. Department of Energy (DOE) patent for a novel uranium‑extraction process. The breakthrough, developed at the company’s research facility in Oak Ridge, Tennessee, promises to lower the energy and chemical footprint of recovering uranium from low‑grade ores and recycled nuclear fuel. Industry analysts say the technology could revitalize domestic uranium supply chains while supporting the nation’s push toward low‑carbon electricity generation.

*Key Developments*
The patented method employs a supercritical fluid—carbon dioxide tuned to specific temperature and pressure thresholds—to selectively solubilize uranium oxides without the need for traditional acid leaching. Laboratory tests show a recovery rate of up to 92 % from ore grades as low as 0.05 % U₃O₈, a threshold that previously rendered mining uneconomical. Compared with conventional solvent‑extraction routes, the process reduces acidic waste by roughly 70 % and cuts operational energy consumption by an estimated 40 %. The DOE awarded the patent under its Advanced Manufacturing Office program, which funds technologies that enhance the competitiveness of U.S. clean‑energy sectors.

*Industry Analysis*
Uranium remains a cornerstone of the nation’s nuclear fleet, which supplies about 20 % of U.S. electricity. However, domestic production has fallen to less than 5 % of annual consumption, making the country reliant on imports from geopolitically sensitive regions. SuperCritical Materials’ innovation addresses two pressing concerns: the environmental toll of conventional mining and the strategic vulnerability of the supply chain. By enabling economic extraction from marginal deposits and reprocessed fuel, the technology could expand the viable resource base by an estimated 15 %–20 % over the next decade. Analysts at Wood Mackenzie note that if scaled, the process could reduce the levelized cost of electricity from new nuclear plants by up to 3 %, strengthening nuclear’s role in a decarbonized grid.

*Future Outlook*
SuperCritical Materials plans to pilot the supercritical extraction system at a partner site in Wyoming by mid‑2026, with the goal of demonstrating continuous operation
