摘　　要：长江大保护和双碳战略对长江船舶的绿色低碳发展提出了很高的要求。以长江液货船为研究对象,研究替代燃料动力系统在全生命周期内的碳足迹。分析低碳和零碳替代燃料的应用现状,针对目标船的动力参数开展液化天然气(LNG)、化石氨和绿氨燃料替代燃料动力系统方案设计,并从全生命周期的角度计算柴油、LNG、化石氨和绿氨动力系统碳足迹。研究结果表明,LNG动力系统的碳足迹相比柴油动力系统低35.11%,绿氨相比化石氨具有更好的减碳潜力。此外,采用不确定性分析方法对替代燃料动力系统生命周期碳足迹结果的可靠性进行评估,为科学、全面地评估替代燃料动力系统的环境友好性提供参考。The protection of the Yangtze River and the strategy of Carbon Peak Carbon Neutrality put forward high requirements for the green and low-carbon development of ships in the Yangtze River. Taking a Yangtze River tanker as the research object, the carbon footprint of alternative power system in the whole life cycle is studied. The application status of low-carbon and zero carbon alternative fuels are analyzed. According to the parameters of the target ship, the alternative power system scheme using LNG, fossil ammonia and green ammonia are designed, then the carbon footprint of diesel, LNG, fossil ammonia and green ammonia power system is calculated from the perspective of whole life cycle. The research results show that the carbon footprint of LNG power system is 35.11% lower than that of diesel power system. Compared with fossil ammonia, green ammonia has better carbon reduction potential. In addition, the uncertainty analysis method is used to evaluate the reliability of the carbon footprint results of the life cycle of the alternative fuel power system, providing a reference for scientific and comprehensive evaluation of the environmental friendliness of the alternative fuel power system.
