Hydrogen Fuel cell vehicle for Mexico City 2020-01-1169

The search for alternative fuel for transport vehicles and also replacement of internal combustion engines in order to reduce the harmful emissions have been forcing the vehicle manufacturers to develop, design and propose technology solutions for meeting the stringent legislative targets. Mexico’s commitment for de-carbonisation of transportation sector and meeting the environmental goals is shaping its policy towards this sector and favours the move towards electrification of the vehicles. Therefore, as an interim solution, the presence of hybrid vehicle is increasing in Mexico City. The aim of the present work is to numerically evaluate the possibility of replacing the internal combustion engines in the existing hybrid vehicles with the Hydrogen fuel cell. This work numerically modelled a Hydrogen fuel cell vehicle based on Toyota MIRAI and validated the fuel economy performance of the vehicle using experimental data. This validated model was used to estimate the fuel economy for real-world drive cycles generated in 2019 from Mexico City. It considered three different drive cycles representing real-world driving in the Metropolitan Area of the Valley of Mexico. This study estimated the amount of reduction in CO2 and other pollutants for the year 2020, and up to 2050 if the internal combustion engine in the electric hybrid vehicles are replaced with the Hydrogen fuel cell. The study also estimated the amount of Hydrogen fuel required for replacing the internal combustion engines with the Hydrogen fuel cell for moving towards electrification of light duty vehicles. Acknowledgments The development of driving cycles in Mexico City was supported by UNAM, with the PAPIIT IG 181010 project.
