Abstract

This study evaluates the fuel economy and emission ratios of C-segment cars comparatively concerning the consumed fuel types. The energy required for specific driving conditions is calculated, and corresponding emission ratios and fuel costs are investigated. Aerodynamic and performance characteristics that are considered in the analysis are presented in detail. In the comparative analysis, diesel and gasoline fuels are included, and biomethane, battery electric, and hydrogen are evaluated for cleaner and economically feasible road transportation options. In all scenarios, hydrogen fuel cell vehicles are evaluated as the lowest well-to-wheel greenhouse gas emitting options, followed by battery electric and biomethane. In terms of fuel economy comparisons in US$, battery electric vehicles offer the lowest fuel cost corresponding to $2.34 for C-segment cars per 100 km of driving range. It is observed that hydrogen is a cost competitive option compared to conventional fuel types as long as the targeted green hydrogen production cost of $6/kg H₂ is accomplished, which is set as a very near-future goal for green hydrogen economy.

使用氢等替代燃料的各种乘用车的比较评估

本研究针对c级轿车所消耗的燃料类型，对其燃油经济性和排放率进行了比较评价。计算了特定工况下所需的能量，并研究了相应的排放比和燃油成本。详细介绍了分析中所考虑的气动特性和性能特性。在比较分析中，柴油和汽油燃料被包括在内，生物甲烷、电池电和氢被评估为更清洁和经济上可行的道路运输选择。在所有情况下，氢燃料电池汽车被评为从油井到车轮温室气体排放最低的选择，其次是电池电动汽车和生物甲烷汽车。在燃油经济性方面，以美元为单位进行比较，纯电动汽车的燃油成本最低，相当于c级车每百公里行驶里程2.34美元。可以观察到，与传统燃料类型相比，氢气是一种具有成本竞争力的选择，只要实现绿色氢气生产成本为6美元/公斤氢气的目标，这是绿色氢经济在不久的将来的目标。
