Could nuclear-powered cargo ships be the future of clean shipping? The NS Savannah once proved it was possible — now, new reactor technologies promise safer, smaller, and more efficient vessels. With global shipping emitting nearly as much CO₂ as Japan, experts say nuclear propulsion could help meet climate goals. But outdated regulations, safety concerns, and lack of infrastructure remain major hurdles. The first modern nuclear ships may set sail in the 2030s — if the industry can overcome these challenges.
