Abstract：Against the backdrop of the global shipping industry's low-carbon transition， the application of clean marine fuels has become a key pathway to achieving carbon emisson reduction targets.This paper systematically reviews the technicalcharacteristics， maturity， emisionreductionpotential，andapplicationscenariosof majorclean fuels such as LNG， methanol，hydrogen，ammonia，and purebattery power. Italsoanalyzes thecurrent application status and development prospects of various clean energy sources in the Pearl River Delta region，considering its shipping structure，route characteristics，and infrastructure conditions.The study shows that the Pearl River Delta region has a solid foundation for developing a diversified clean fuel system，but still faces challenges such as insuffcient green fuel supply， inadequate infrastructure，and key technologicalbotlenecks.Inthe future，measures such as scenario-specific adaptation，accelerated infrastructure deployment，and breakthroughs inkey technologies should be promoted to build a green， low-carbon， and effcient modern shipping system.

Key words： ship emission reduction; Pearl River Delta; LNG; methanol; hydrogen energy; ammonia energy; electric vessel
