Nuclear technology is poised to revolutionize maritime energy, enhancing propulsion, ports, and offshore platforms, according to the American Journal of
Nuclear technology is re-emerging as a transformative force for the maritime industry, offering clean, high-density energy for propulsion, ports, fuels, and offshore platforms, reports the American Journal of Transportation.
A convergence of energy transition, regulation, and innovation is driving new investment in commercial nuclear power. Advanced reactor designs, evolving regulatory frameworks, and public-private partnerships are bringing maritime nuclear applications closer to feasibility.
Beyond propulsion, nuclear power could underpin a new offshore ecosystem. Shoreside plants may produce hydrogen and ammonia, while floating installations could support data centers, synthetic fuel platforms, and desalination systems.
The first deployments are expected to be floating nuclear power barges, supplying electricity to ports, islands, and coastal communities. Regulators may find these easier to approve due to their stationary design and controlled safety measures.
By the 2030s, commercial floating nuclear plants could stabilize renewable-heavy grids and support hydrogen production. Offshore nuclear-powered data centers could account for 10 percent of the global market by 2050, while desalination platforms could address water scarcity.
Nuclear propulsion for ships will likely begin along defined corridors between nations with mature regulatory frameworks. These corridors would provide controlled environments for early deployment and integration with energy and logistics networks.
ABS, which has been involved in maritime nuclear technology since 1962, is modernizing outdated standards with its Floating Nuclear Power Plant Code. Joint projects with Core Power and Athlos are preparing for deployment in the Mediterranean.
ABS has issued multiple approvals in principle for advanced nuclear concepts, including molten salt reactor containerships and nuclear-powered LNG carriers. Collaborations with the US Department of Energy and MIT aim to advance technology-neutral standards.
Policy incentives are aligning with industrial capability. A US-UK agreement signed in September 2025 commits both nations to civil maritime nuclear development, including a dedicated shipping corridor. Tax credits and clean energy incentives could accelerate adoption.
ABS stated that the industry now has a once-in-a-generation opportunity to lead a transformational shift. With modern standards and international collaboration, nuclear technology could redefine what is possible at sea.
