Hydrogen as a sustainable transportation fuel

This review examines the potential direct and indirect (synthetic fuels) uses of hydrogen in road, rail, air, and marine transportation. Key physical properties of hydrogen (e.g., energy density) are presented and contrasted against conventional fuels. The costs and emissions of current and future hydrogen production methods are characterized, and the challenges of transporting, storing, distributing, and dispensing hydrogen are highlighted. The sustainability of hydrogen use is evaluated in terms of CO 2 and other air pollutant emissions, energy efficiency and intensity, critical material use, and water consumption. Electrification is much more energy efficient than using hydrogen in transportation. Hydrogen…
