China’s Jiangnan Shipyard has detailed a 14,000 TEU nuclear-powered container ship equipped with a 200 MW thorium molten salt reactor. The design, developed under China State Shipbuilding Corporation, follows successful operation of a thorium reactor prototype in the Gobi Desert. The sealed modular system requires no refueling for ten years and operates at low pressure without water cooling, minimizing safety risks.

This vessel advances maritime decarbonization. Global shipping contributes 3 percent of CO2 emissions, and IMO regulations mandate net-zero by 2050. Thorium propulsion enables transoceanic voyages with near-zero emissions and 30 to 50 percent lower fuel costs compared to conventional vessels. China’s abundant thorium reserves support long-term scalability.

U.S. shipbuilders and operators face both competition and opportunity. Domestic expertise in naval nuclear systems, such as those in Seawolf-class submarines, positions firms to adapt thorium technology for commercial use. Regulatory approval and public acceptance remain hurdles, but pilot projects under ARPA-E or Jones Act compliance could accelerate adoption.

Strategic expansion is essential. China offers component supply and testing partnerships, while Brazil’s growing demand for efficient bulk transport aligns with thorium applications. A targeted presence in Santos, supported by Brazil’s investor visa requiring minimal residency, enables market entry and risk diversification.

China’s prototype targets trials by 2027. U.S. firms must evaluate thorium integration, secure funding, and establish international footholds to maintain competitiveness in next-generation maritime technology.
