Hydrogen energy is essential in the transition to sustainable transportation planning, providing a clean and efficient alternative traditional fossil fuels. As versatile carrier, hydrogen facilitates decarbonization of diverse modes, including passenger vehicles, heavy-duty trucks, trains, maritime vessels. To justify clarify role this study conducts comprehensive techno-economic environmental assessment production USA, Europe, China. Utilizing Shlaer–Mellor method for policy modeling, analysis highlights regional differences offers actionable insights inform strategic decisions frameworks advancing adoption. potential was assessed from solar biomass resources, with results showing that solar-based significantly more efficient, producing 704 tons/yr/km2, compared 5.7 tons/yr/km2 biomass. A Monte Carlo simulation conducted project emissions market share gasoline vehicles 2024 2050. The indicate could achieve near-zero capture approximately 30% by 2050, while will decline 60% higher emissions. Furthermore, using USA yields per capita output 330,513 kg/yr, 6079 kg/yr concludes hydrogen, particularly renewable sources, holds significant reducing greenhouse gas emissions, China focused on addressing dependence, air pollution, technological development sector.
