At the American Nuclear Society’s Annual Conference on June 1, an executive session covered the increasingly prominent subject of nuclear applications in the civilian maritime industry.

Panelists who presented during “Advancing Nuclear Powered Maritime Shipping” highlighted the fact that the commercial shipping industry, the nuclear industry, and government agencies are looking at nuclear power as a solution for reducing greenhouse gas emissions, 3 percent of which are attributed to commercial shipping.

The American Bureau of Shipping has joined a joint development project with the HD Hyundai divisions of Korea Shipbuilding & Offshore Engineering (HD KSOE) and HD Hyundai Samho Heavy Industries (HD HSHI) to advance the conceptual design and assess the technical feasibility of a nuclear-powered electric propulsion system for large container ships.

The project, “Conceptual Design of a Nuclear-Powered Electric Propulsion System,” will focus on developing the basic design, electrical component specifications, and arrangement plans of a nuclear propulsion system for a 16,000-TEU ship (that is, a massive vessel designed to carry 16,000 20-foot-equivalent units). It would be the first nuclear-powered commercial container vessel.

In an article published on March 5, Axios reviews the ways the world’s maritime companies are trying to decarbonize. The maritime industry, “from ferries to freighters—is trying to navigate a once-in-a-century transition away from fossil fuels to new, cleaner means of propulsion,” the article explains.

Emissions from shipping: The article notes that the world’s economy relies on international shipping, with more than 90 percent of global trade traveling via maritime vessels. The issue, though, is that “the vessels burn about 4 million barrels of oil a day, accounting for almost 3 percent of the world’s carbon emissions.” The article then cites a United Nations report from 2018 that sets greenhouse gas reduction targets of 50 percent by 2050 compared to 2008 levels.
