Abstract

In order to better achieve the goal of low carbon emissions from vehicles, a whole life cycle assessment of hydrogen-fueled internal combustion engine vehicles has been conducted in recent years. Based on the study of hydrogen use around the world, we studied the emission and economic performance of hydrogen-fueled internal combustion engine vehicles from the beginning of hydrogen production to the end of use (Well-to-Wheel, WTW) based on the whole life cycle evaluation method. The results show that the overall environmental impact of hydrogen production by steam reforming of natural gas is the smallest, and that the rational use of "abandoned electricity" for hydrogen production from electrolytic water in the western part of China significantly reduces the overall environmental impact and the cost of hydrogen production. In the use phase, the emissions are less, which not only can meet the National 6 emission standard, but also can reach higher emission standard after adding exhaust gas recirculation (EGR). From the whole life cycle point of view, hydrogen-fueled internal combustion engine has a very good development prospect.

基于全生命周期评价方法的氢内燃机汽车研究
为了更好地实现汽车低碳排放的目标,近年来对氢燃料内燃机汽车进行了全生命周期评估。在国内外氢气利用研究的基础上,基于全生命周期评价方法,研究了氢燃料内燃机汽车从制氢开始到使用结束(井到车轮,WTW)的排放和经济性。研究结果表明,天然气蒸汽重整制氢对环境的总体影响最小,西部地区合理利用“废电”电解水制氢可显著降低整体环境影响和制氢成本。在使用阶段,排放少,不仅可以达到国六排放标准,而且在加入废气再循环(EGR)后可以达到更高的排放标准。从全生命周期来看,氢燃料内燃机具有很好的发展前景。
