The utilization of “green” hydrogen in transportation areas gives rise to production- and supply infrastructure-related challenges; therefore, its wider application automotive transport would lead higher demand with cost reduction a faster expansion the refuelling network. This study presents energy environmental performance indicators analyses Nissan Qashqai J10 engine during Worldwide Harmonised Light Vehicles Test Cycle (WLTC), replacing conventional fossil gasoline dual-fuel (D-F) hydrogen. Numerical modelling was conducted using AVL Cruise™ (Version R2022.2) software, utilizing torque, fuel consumption, data HR16DE obtained through experimental testing across wide range loads speeds on an test bench. investigation carried out two stages: pure (G100); injecting additive into intake air, constituting 5% mass (G95H5). Following similar stages, numerical vehicle’s technical specifications calculate load speed throughout WLTC range. Instant consumption pollutant emissions (CO, CH, NOx) were determined for various driving modes maps. CO2 calculated considering composition consumption. By integrating instant values, total specific calculated. As result, this identified effect improving efficiency, reducing incomplete combustion products lowering greenhouse gas (CO2) under modes. Finally, results compared requirements EU standards.
