燃料电池汽车氢源生命周期分析

运用生命周期评价方法对使用不同氢源的燃料电池汽车进行了分析.经过目的与范围的确定、清单分析、影响评价和结果解释,表明电解制氢方案的污染排放明显高于甲醇重整和汽油重整方案,而甲醇重整和汽油重整方案又高于天然气制氢和煤制氢方案,对于相同的制氢方案,液氢方案的排放略高于气氢方案. 

Life Cycle Assessment of Hydrogen Sources of Fuel Cell Vehicles

Life cycle assessment is used to analyze the fuel cell vehicles using different hydrogen sources.After goal and scope definition,inventory analysis,impact assessment and interpretation,it is showed that the emitted pollutants of vehicles using hydrogen produced by water electrolyzer are more than those of methanol reformer vehicles and gasoline reformer vehicles,and the emitted pollutants of methanol reformer vehicles and gasoline reformer vehicles are more than those of vehicles using hydrogen produced by natural gas reformer or coal gasification.For vehicles using the same hydrogen production method,the study showed that the emitted pollutants of liquid hydrogen method are a little more than those of gas hydrogen method.
