Read original articleThe International Council on Clean Transportation (ICCT) recently published a lifecycle assessment (LCA) report on road vehicle decarbonization in Europe that positions hydrogen fuel cell electric vehicles (FCEVs) as a climate-friendly alternative comparable to battery electric vehicles (BEVs). However, the report has been criticized for focusing on passenger cars in 2025—a segment where hydrogen vehicles have effectively failed in Europe—and ignoring the current market reality where electric buses and heavy goods vehicles dominate. Critics argue that including a "dead segment" like passenger FCEVs misrepresents the state of hydrogen technology and its viability compared to BEVs.
More importantly, the ICCT report is faulted for not adequately accounting for hydrogen leakage throughout the supply chain and for using the 20-year global warming potential (GWP20) metric instead of the more common 100-year metric (GWP100). Hydrogen leakage occurs at multiple stages—electrolysis, liquefaction, pipeline transmission, trucking, refueling,
