Maritime transportation, responsible for over 80% of global freight movement, is a major contributor to environmental emissions, making the development of effective emission reduction strategies crucial for the protection of marine ecosystems. As regulatory pressures, environmental concerns, and resource efficiency take center stage, alternative fuels such as hydrogen, LPG, am-monia, LNG and biofuels, along with nuclear power, have gained significant attention in the maritime industry. Nuclear energy, in particular, has emerged as promising alternative for reducing carbon emissions in marine vessels, aligning with the International Mar-itime Organization’s (IMO) decarbonization and fuel efficiency targets. While nuclear-powered vessels have been deployed in ice-breaker, naval, and supply sectors, their use remains limited, primarily due to restricted operational ranges. This paper offers a thorough analysis of nuclear-powered cargo ship generation methods, reactor technologies, and safety protocols. Strengthening collaboration between regulatory bodies, pilot projects, and stakeholders is essential for refining safety standards and ensuring regulatory compliance. Public acceptance is another key factor, requiring transparent environmental impact assessments and proactive communication to foster trust and align nuclear-powered vessels with global sustainability objectives. Despite existing challenges, nuclear propulsion presents opportunities for innovation and international cooperation. By addressing regulatory and societal barriers through coordinated efforts and policies, nuclear power could become a cornerstone of the maritime industry's transition to a sustainable, efficient, and technolog-ically advanced future. Its successful implementation would play a vital role in advancing low-carbon shipping and contributing to the broader global energy transition.
Abstract
Maritime transportation, responsible for over 80% of global freight movement, is a major contributor to environmental emissions, making the development of effective emission reduction strategies crucial for the protection of marine ecosystems.
