Beschreibung:
<jats:p>Converting the world's fossil‐fuel onroad vehicles (FFOV) to hydrogen fuel cell vehicles (HFCV), where the H<jats:sub>2</jats:sub> is produced by wind‐powered electrolysis, is estimated to reduce global fossil, biofuel, and biomass‐burning emissions of CO<jats:sub>2</jats:sub> by ∼13.4%, NO<jats:sub>x</jats:sub> ∼23.0%, nonmethane organic gases ∼18.9%, black carbon ∼8% H<jats:sub>2</jats:sub> ∼3.2% (at 3% leakage), and H<jats:sub>2</jats:sub>O ∼0.2%. Over 10 years, such reductions were calculated to reduce tropospheric CO ∼5%, NO<jats:sub>x</jats:sub> ∼5–13%, most organic gases ∼3–15%, OH ∼4%, ozone ∼6%, and PAN ∼13%, but to increase tropospheric CH<jats:sub>4</jats:sub> ∼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.</jats:p>
