Abstract:

The hydrogen fuel cell heavy-duty commercial vehicle (FCHCV) is one of the ideal solutions to address energy security and greenhouse gas emissions. However, the full life cycle energy consumption and emissions of FCHCVs under key parameter scenario simulations are still unclear. This study evaluates a domestic FCHCV based on the life cycle assessment method, with a focus on analyzing the life cycle energy consumption and emissions results of FCHCV under four hydrogen production paths, which are coal gasification, methane reforming, mixed power electrolysis, and photovoltaic electrolysis. Uncertainty analyses are conducted on the fuel cell stack degradation, hydrogen consumption per hundred kilometers, and vehicle lifespan. The results show that the FCHCV using photovoltaic electrolysis has the lowest life cycle energy consumption and carbon emissions. Improving fuel economy and vehicle lifespan, and delaying fuel cell stack degradation can effectively improve the environmental impact of FCHCV during the life cycle.
