Amid growing global concerns over climate change impacts and increasingly stringent environmental regulations, significant technological advancements have been achieved in​​marine green power systems​​ in recent years. Concurrently, there is an escalating operational demand for systematic evaluation and selection of these sustainable propulsion solutions. This study proposes an innovative multi-objective optimization-based methodology for optimal selection of ​​marine green power systems​​. A comprehensive technical database encompassing both existing and emerging technologies (including low-carbon fuel engines, fuel cell systems, battery systems, and hybrid configurations) has been established. This is integrated with an analytical framework evaluating five critical performance indicators: lifecycle economic efficiency, environmental emissions performance (covering greenhouse gases and air pollutants), operational safety, global fuel availability and infrastructure readiness, and technology readiness levels (TRL). The developed integrated approach yields a scientifically rigorous yet operationally practical multi-criteria evaluation system. This system provides accurate, data-driven decision support for shipowners and maritime stakeholders, facilitating informed choices in fleet renewal and decarbonization strategies.

摘要

Amid growing global concerns over climate change impacts and increasingly stringent environmental regulations, significant technological advancements have been achieved in​​marine green power systems​​ in recent years. Concurrently, there is an escalating operational demand for systematic evaluation and selection of these sustainable propulsion solutions. This study proposes an innovative multi-objective optimization-based methodology for optimal selection of ​​marine green power systems​​. A comprehensive technical database encompassing both existing and emerging technologies (including low-carbon fuel engines, fuel cell systems, battery systems, and hybrid configurations) has been established. This is integrated with an analytical framework evaluating five critical performance indicators: lifecycle economic efficiency, environmental emissions performance (covering greenhouse gases and air pollutants), operational safety, global fuel availability and infrastructure readiness, and technology readiness levels (TRL). The developed integrated approach yields a scientifically rigorous yet operationally practical multi-criteria evaluation system. This system provides accurate, data-driven decision support for shipowners and maritime stakeholders, facilitating informed choices in fleet renewal and decarbonization strategies.
