U.S.-based energy technology company EnergyX has announced the development of a new platform aimed at producing nuclear-grade lithium isotopes, marking a significant step toward supplying advanced materials for next-generation nuclear energy systems. The initiative, called NUKE-it™, focuses on the production of high-purity lithium compounds and enriched lithium isotopes that are essential for both fusion and advanced fission reactors.
Lithium isotopes play a critical role in nuclear technologies. In particular, lithium-6 (⁶Li) is widely used in fusion systems to produce tritium, a key fuel for deuterium–tritium fusion reactions, while lithium-7 (⁷Li) is required in molten salt reactors due to its low neutron absorption and high chemical stability. By targeting approximately 15% enriched lithium-6 and ultra-high-purity lithium-7, EnergyX aims to address a growing supply gap for reactor-grade materials needed in emerging nuclear energy systems.
The company’s approach builds on its existing lithium extraction expertise, particularly the proprietary GET-Lit™ direct lithium extraction (DLE) platform, which integrates extraction, purification, and material conversion technologies. According to the company, several of these separation and purification techniques can be adapted for lithium isotope production, potentially enabling more efficient and scalable manufacturing of nuclear-grade lithium materials.
EnergyX plans to begin isotope separation pilot operations in 2026, followed by partner validation by 2027 and a pre-commercial production facility by 2028. A full commercial nuclear materials hub is targeted by the end of the decade.
The announcement highlights the increasing convergence between critical minerals processing and nuclear energy technologies. As interest in fusion reactors and advanced fission systems grows globally, the availability of high-purity lithium isotopes is becoming an important strategic issue for energy security and clean power development.
