Emerald Nuclear's marine reactor project wins $2.15M Norwegian grant
What's the deal? The Research Council of NorwayDealroom has a profile for this one. Try Dealroom → has awarded a grant of US$2.42M to the Marine Nuclear Propulsion System (MarNuPS) project, led by the Norwegian subsidiary of US reactor startup Emerald NuclearDealroom has a profile for this one. Try Dealroom →. The grant supports the first phase of research into a full-scale, integrated nuclear propulsion system for ships.
What's the endgame? Emerald Nuclear is a microreactor startup focused on ship and barge applications. Its "GEM" concept, a 5MW electric reactor, would run on TRISO-coated uranium fuel pellets, with refueling via reactor swap-out every five to 15 years. Its business plan is based on leasing reactors rather than selling them.
Who else is involved? Partners include offshore operator Island Offshore — Emerald's first commercial customer — FincantieriDealroom has a profile for this one. Try Dealroom →-owned shipbuilder VARD and Vard Electro, research center NTNU, Imperial College London, and machinery-monitoring firm Maskindynamikk. VARD handles ship design and system integration; Vard Electro covers energy management and automation.
Why now? The grant moves the program from design and analysis toward building and testing. A full-scale test facility is planned for 2027 in Stette, near Ålesund, with the first system test using electric heating rather than nuclear fuel to simulate the reactor's heat source. The consortium targets deployment on a vessel in 2031–2032.
By the numbers: The $2.15 million grant is a modest share of a first phase expected to cost roughly $15.6 million. "This award is evidence of validation and momentum rather than the scale of the ambition," said Hallgeir Juliebø, Emerald's co-founder and chief commercial officer.
The signal: The timing matters. The International Maritime Organization is revising its 1981 nuclear-ship safety code and SOLAS provisions, with a framework targeted for adoption by 2030 — close to the project's deployment goal. The grant is early validation and testing support, not a sign that commercial nuclear shipping is imminent.
