Consortium Explores Installing Nuclear Fusion Reactor on Ship
A joint industry project led by the American Bureau of Shipping (ABS) is studying the feasibility of installing a nuclear fusion reactor onboard a vessel.
The proposed vessel would be a 71.4-m DP2 anchor-handling power barge supply vessel powered by two 8,000 kWe steam generators driven by a compact fusion reactor, as per an ABS presentation at Posidonia 2026 shared with Ship & Bunker.
Battery systems would provide up to six hours of backup power.
The project brings together ABS, fusion technology developer nT-Tao, Siemens Energy, P&P Marine Consultants and TEMISTh to evaluate the technical, safety and regulatory requirements for a fusion-powered offshore power barge.
The study will examine vessel integration, safety risks, economics and regulatory requirements.
One key challenge is that no classification framework currently exists for a fusion reactor on a marine vessel.
The goal is to have a commercial prototype ready by approximately 2032.
While nuclear energy has been used in naval vessels, its adoption in commercial shipping has been hindered by regulatory and safety concerns.
ABS has already been involved in various projects to promote the use of nuclear technology in shipping, including a joint project with HD Hyundai to study the conceptual design of a nuclear-powered electric propulsion system for container ships.
