Nuclear Energy Supply Chain Gets Boost as Molten Salt Solutions Secures $7M for Lithium Isotope Production

## Nuclear Energy Supply Chain Gets Boost as Molten Salt Solutions Secures $7M for Lithium Isotope Production Molten Salt Solutions, Inc. (MSS), a Santa Fe, New Mexico-based energy technology company, has secured $7 million in funding to accelerate pilot-scale production of lithium-6 and lithium-7 isotopes — materials considered essential to the development of advanced nuclear reactor technologies, according to a PR Newswire release dated August 31, 2026. The funding round is intended to strengthen domestic supply chains for next-generation nuclear energy, a sector that has attracted growing interest from heavy industry stakeholders, including segments of the maritime community exploring low- and zero-emission propulsion alternatives. ### Why This Matters for Maritime While MSS operates outside the maritime sector directly, the broader nuclear energy landscape is increasingly relevant to shipping. Advanced small modular reactors (SMRs) and molten salt reactor concepts have been cited by researchers and regulators as potential long-horizon solutions for decarbonising deep-sea shipping — a segment where battery-electric and hydrogen solutions face significant energy density challenges on extended voyages. Lithium-7, one of the isotopes MSS is targeting for scaled production, is a key coolant material in certain molten salt reactor designs. A reliable domestic supply of such materials could reduce barriers to commercialising reactor technologies that may one day find application in large vessel propulsion or shore-based bunkering infrastructure powered by advanced nuclear generation. ### Domestic Supply Chain Focus The investment reflects a wider strategic push in the United States to reduce dependence on foreign sources for critical energy materials. MSS states that the capital will be deployed toward pilot-scale production capabilities, moving the company beyond laboratory-stage operations. The maritime industry's energy transition continues to draw investment across a broad spectrum of technologies — from green ammonia and methanol to wind-assisted propulsion and, increasingly, nuclear alternatives. Developments in upstream supply chains, such as isotope enrichment, form part of the foundational infrastructure that will determine which technologies ultimately reach commercial viability at sea. *Source: PR Newswire*
