In the 1960s, nuclear-powered merchant ships like the U.S. "Savannah" and the German ore carrier "Otto Hahn" were celebrated as technological innovations. Despite their technical feasibility, these projects failed economically due to high costs. Today, amid increasing pressure to reduce CO₂ emissions and fluctuating energy prices, the option of nuclear propulsion is being discussed again.
Last Thursday, the U.S. government announced a formal initiative to develop small modular reactors (SMRs) for commercial shipping. Donald Trump instructed the Maritime Administration (MARAD) to discuss with industry and researchers how nuclear propulsion could be implemented on a large scale in American fleets.
This initiative could revolutionize the shipping industry by providing a more environmentally friendly alternative to conventional fossil fuels. Experts emphasize that the development of compact reactors will be crucial in addressing the challenges of today's energy prices and climate goals.
The return to nuclear-powered ships could not only reduce emissions but also decrease dependence on fossil fuels. The discussion around this technology highlights how priorities in shipping are changing to meet the demands of the energy transition.
