摘要：Fuel cell vehicles are regarded as the ultimate goal of new energy vehicles because of their high energy conversion efficiency and clean product emissions. This study is based on China's localized industrial and transportation data, combined with the "Life Cycle Assessment (LCA)" approach, and the use of the GREET model for the analysis of the WTW phase of the hydrogen energy system. Sensitivity analysis of hydrogen source system solutions by defining sensitivity factors. This study believes that the overall environmental benefits of natural gas reforming hydrogen production + high-pressure hydrogen gas + pipeline transportation plan are the best, and the relatively flexible and manoeuvrable ground high-pressure hydrogen trailer transportation method can be used as a supplementary solution for hydrogen energy transportation. When the ratio of coal to electricity is reduced below 40%, the environmental benefits of hydrogen production from electrolyzed water are expected to decrease to the same level as current level of hydrogen production from coal gasification.
