Energy chief envisions nuclear reactors powering future global shipping fleet

During an International Atomic Energy Agency event on sea-based atomic technologies, Energy Secretary Chris Wright argued that nuclear power will soon power the world’s shipping industry, offering a carbon-free source that could dramatically reduce trade costs. He described a future where ships need refueling only every few years, allowing faster voyages and greater cargo loads while eliminating dependence on oil or gas.

The Trump administration has formalized interest in offshore nuclear through a memorandum of understanding between the Interior Department’s Marine Minerals Administration and the Nuclear Regulatory Commission, targeting the outer continental shelf. Critics point out that offshore projects are expensive, citing offshore wind costs as an example, and suggest small modular reactors will more likely be placed on vessels, ports, refineries, or offshore platforms.

Nano Nuclear CEO James Walker echoed this view, noting niche possibilities for floating reactors in regions where land-based nuclear faces barriers. Wright also hinted that maritime nuclear could deliver power to nations lacking domestic nuclear capacity, though a timeline for deployment remains unclear.
