Answer: NOT GIVEN
An alternative pathway relies on Hydrogen Fuel Cell Vehicles (FCVs). These vehicles utilize a chemical process where hydrogen gas combines with oxygen from the air to generate electricity, leaving water vapor as the sole byproduct. FCVs boast a driving range comparable to conventional petrol cars and can be refueled in a matter of minutes. Despite these advantages, the commercialization of hydrogen transport faces steep economic hurdles. Constructing a nationwide hydrogen refueling infrastructure demands astronomical capital investment. Moreover, the vast majority of commercial hydrogen is currently extracted from natural gas through steam methane reforming, a process that releases substantial amounts of carbon dioxide, thereby undermining the vehicle’s environmental credentials unless "green hydrogen" produced via water electrolysis becomes commercially viable.
