Scientific paper

Converting the world's fossil-fuel onroad vehicles (FFOV) to hydrogen fuel cell vehicles (HFCV), where the H2 is produced by wind-powered electrolysis, is estimated to reduce global fossil, biofuel, and biomass-burning emissions of CO2 by ~13.4%, NOx ~23.0%, nonmethane organic gases ~18.9%, black carbon ~8% H2 ~3.2% (at 3% leakage), and H2O ~0.2%. Over 10 years, such reductions were calculated to reduce tropospheric CO ~5%, NOx ~5-13%, most organic gases ~3-15%, OH ~4%, ozone ~6%, and PAN ~13%, but to increase tropospheric CH4 ~0.25% due to the lower OH. Lower OH also increased upper tropospheric/lower stratospheric ozone, increasing its global column by ~0.41%. WHFCV cooled the troposphere and warmed the stratosphere, reduced aerosol and cloud surface areas, and increased precipitation. Other renewable-powered HFCV or battery electric vehicles should have similar impacts.
