根据加拿大四个主要省份的相关情况，对氢燃料电池乘用车进行了全面的生命周期评价。结果提供了三种替代制氢方法，即电解，热化学水裂解，和天然气的蒸汽甲烷重整，并与传统的汽油车作为参考案例进行比较。在所有四个省，除了阿尔伯塔的电解法外，预计所有三种制氢方法都会显著减少温室气体和标准空气污染物排放，因为阿尔伯塔省的大部分电力都是由化石燃料产生的。由于可再生废热的潜在利用，热化学制氢在所有省份显示出最有利的结果，其次是魁北克和不列颠哥伦比亚省的可再生水力发电电解。当用于生产的可再生能源与用于压缩和分配的低排放电力来源相结合时，例如通过利用安大略核电的废热和废电，可以获得生命周期减排方面的最佳点。预计由天然气生产的氢气的燃料成本最低，天然气在加拿大储量丰富，可以在所有省份的FCV实施中在减排和经济效益之间提供合理的平衡。版权所有（C）2015，氢能出版物有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
A comprehensive life cycle assessment of hydrogen fuel cell passenger vehicles (FCVs) is conducted based on relevant conditions for four major Canadian provinces. Results are provided for three alternative hydrogen production methods, namely electrolysis, thermochemical water splitting, and steam methane reforming of natural gas, and compared against conventional gasoline vehicles as a reference case. Significant reductions in greenhouse gas and criteria air contaminant emissions are predicted from all three hydrogen production methods in all four provinces, except for electrolysis in Alberta where most electricity is generated from fossil fuels. Thermochemical hydrogen production shows the most favorable results in all provinces due to the prospective use of renewable waste heat, followed by electrolysis from renewable hydroelectric power in Quebec and British Columbia. The sweet spot in terms of life cycle emission reductions is obtained when a renewable energy source for production is combined with a low-emission electricity source for compression and distribution, for example by utilizing waste heat and electricity from nuclear power in Ontario. The lowest fuel costs are predicted for hydrogen produced from natural gas, which is abundant in Canada and can provide a reasonable balance between emission reductions and economic benefits for FCV implementation across all provinces.
