Ship hydrogen-electric hybrid power system model and life cycle carbon emission assessment method船舶氢电混合动力系统建模与全生命周期碳排放评价
A life cycle carbon emission assessment method is proposed to comprehensively evaluate the carbon emission reduction capacity of hydrogen-electric hybrid ships.
First, an energy flow model of the power system is established using the Matlab/Simulink software platform. Hydrogen consumption and electricity consumption under actual operating conditions are then calculated, and the life cycle carbon emissions are obtained. Finally, sensitivity analysis is performed on carbon emissions from different power sources and hydrogen sources.
The results of an inland river ferry show that compared with the traditional diesel engine power system, the hydrogen-electric hybrid system can reduce carbon emissions by 30.24% in one operation cycle. The sensitivity analysis results show that the carbon emissions of the hydrogen-electric hybrid system are not necessarily better than those of the traditional diesel power system, so it is recommended to use renewable energy for hydrogen production and power generation to significantly reduce carbon emissions (up to 94.2%).
The results of this study can provide references for the power system design of green ships.
为全面评价氢电混合动力船舶的碳减排能力，提出全生命周期碳排放评价方法。
首先，基于Matlab/Simulink平台建立动力系统能量流模型；然后，计算实船营运工况下的耗氢量和耗电量，进而得出全生命周期碳排放量；最后，针对不同电能来源和氢气来源，对碳排放进行敏感性分析。
某内河渡轮的计算结果表明，相较于传统柴油动力系统，氢电混合动力系统在一个营运周期内可以减少30.24%的碳排放。敏感性分析结果表明，氢电混合动力系统的全生命周期碳排放并非必然优于传统柴油动力系统，故建议采用可再生能源进行制氢和发电，以大幅降低碳排放量（最多可减少94.2%）。
研究成果可为绿色船舶的动力系统设计提供参考。
