| dc.description.abstractEN | The paper comprehensively analyzes the technological, economic and regulatory parameters that affect the transition of bulk carriers towards decarbonization, with an emphasis on technologies such as LNG, ammonia (NH₃), hydrogen (H₂) and nuclear Small Modular Reactors (SMR) on Supramax/Ultramax type ships. In particular, critical variables such as CAPEX/OPEX, ETS compliance costs, ROI and payback period, operational impacts on TCE, technological maturity and infrastructure availability and risks (legal, insurance, social) are examined and a comparative analysis of scenarios with LNG, ammonia, hydrogen and SMR fuels is carried out, recording advantages/disadvantages per scenario, technological maturity and financial performance. Each technology is evaluated based on the size and type of ship and the nature of the cargo, providing targeted strategies for shipowners, while the sensitivity of the scenarios to the increase in fuel price (+50%) is also presented, calculating the impact on TCE and on the payback period. In conclusion, it is argued that there is no one technology that fits all. Shipowners should adopt differentiated strategies based on the economic viability of each option, regulatory stability and their commercial needs, adopting models such as LNG retrofit, Ammonia-ready newbuilds and SMR-transferable in the long term. | el |
