Fluxnium Develops Seawater Uranium Extraction Technology for Long-Term Nuclear Fuel Supply

#clean tech #uranium #startups #nuclear power #climate

Fluxnium developed a seawater uranium extraction method using polymer fibers that reduces costs below $200 per pound, potentially solving nuclear fuel supply challenges. The technology could enable 50,000 years of nuclear fuel from ocean uranium reserves, addressing geopolitical risks in uranium sourcing.

Fluxnium's fibers can extract uranium directly from seawater, which has enough of the nuclear fuel to power thousands of generations.
