Lifecycle climate change impacts of battery- and fuel cell electric vehicles: Effects of driving range and fuel chains-Presented at EVS 31 EVTeC 2018, Kobe, Japan, October 1 - 3, 2018

摘要

The factors that affect the climate change impact of mid-sized battery electric vehicles (BEVs) and fuel cell electric vehicles (FCEVs) are investigated using lifecycle assessment. For BEVs, these factors are different battery sizes, which influence single-charge driving range, and charging electricity sources. For FCEVs, different hydrogen production pathways are investigated to account for the uncertainty of future technology development. We find that in most scenarios, FCEVs have lower climate impacts than BEVs. Exceptions include the case of hydrogen produced via electrolysis using the average European grid mix, and BEVs charged with electricity from wind-power.
