About
Fluxnium is building a domestic uranium supply by passively adsorbing dissolved uranium from seawater onto high-surface-area polymer fibers deployed on aquaculture-style longlines. The company says the approach draws on chemistry licensed from U.S. Department of Energy national labs, with yellowcake sold into the existing utility procurement supply chain and no mine tailings. Public coverage notes a seed round led by Congruent Ventures with participation from Active Impact Investments and Constellation Energy. Founder and CEO Jeff Green is a repeat founder (Stamps.com, NanoH2O, 1PointFive).
