Effects of wind-powered hydrogen fuel cell vehicles on stratospheric ozone and global climate

Converting the world's fossil-fuel onroad vehicles (FFOV) to hydrogen fuel cell vehicles (HFCV), where the H(2) is produced by wind-powered electrolysis, is estimated to reduce global fossil, biofuel, and biomass-burning emissions of CO(2) by similar to 13.4%, NO(x) similar to 23.0%, nonmethane organic gases similar to 18.9%, black carbon similar to 8% H(2) similar to 3.2% (at 3% leakage), and H(2)O similar to 0.2%. Over 10 years, such reductions were calculated to reduce tropospheric CO similar to 5%, NO(x) similar to 5-13%, most organic gases similar to 3-15%, OH similar to 4%, ozone similar to 6%, and PAN similar to 13%, but to increase tropospheric CH(4) similar to 0.25% due to the lower OH. Lower OH also increased upper tropospheric/lower stratospheric ozone, increasing its global column by similar to 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.
