Abstract

To compare the environmental impact and carbon footprint of gray hydrogen, blue hydrogen, and green hydrogen, inventories were obtained through literature research. Some inventories that were not available in China were obtained through foreign inventories combined with localized power conversion. The localized end-point destructive life cycle impact assessment method was used to calculate the environmental impact potential of the raw material acquisition, transportation, and hydrogen production stages of five hydrogen products. The carbon footprint was calculated, and the sensitivity analysis and uncertainty analysis were carried out and compared with the ReCiPe method. The results showed that: ① The environmental impact from large to small was: gray hydrogen (coal) (1 203 mPt·kg-1) > blue hydrogen (coal) (876 mPt·kg-1) > gray hydrogen (gas) (492 mPt·kg-1) > green hydrogen (323 mPt·kg-1) > blue hydrogen (gas) (252 mPt·kg-1). The environmental impacts of gray hydrogen and blue hydrogen were mainly concentrated in climate change, fine particulate matter formation, and fossil fuels. The environmental impacts of green hydrogen were mainly concentrated in climate change, fine particulate matter formation, fossil fuels, and mineral resources. ② The carbon footprint from large to small was: gray hydrogen (coal) (23.79 kg·kg-1, measured by CO2eq, the same below) > blue hydrogen (coal) (11.07 kg·kg-1) > gray hydrogen (gas) (10.97 kg·kg-1) > blue hydrogen (gas) (3.47 kg·kg-1) > green hydrogen (1.97 kg·kg-1). Direct carbon emissions in the production process of gray hydrogen and blue hydrogen accounted for the largest proportion, whereas that of green hydrogen accounted for a large proportion of power input. ③ Measures to reduce environmental impact and carbon emissions include reducing direct emissions of pollutants and greenhouse gases, reducing power consumption, and strengthening raw material substitution and reduction.

[典型氢能源产品的生命周期评估和碳足迹比较]。
为了比较灰氢、蓝氢和绿氢对环境的影响和碳足迹,我们通过文献研究获得了相关清单。一些中国没有的清单则通过国外清单结合本地化动力转换获得。采用本地化终端破坏性生命周期影响评估方法,计算了五种氢气产品在原材料获取、运输和制氢阶段的环境影响潜力。计算了碳足迹,进行了敏感性分析和不确定性分析,并与 ReCiPe 方法进行了比较。结果表明: ① 对环境的影响由大到小依次为:灰氢(煤)(1 203 mPt-kg-1)>;蓝氢(煤)(876mPt-kg-1)。>;灰色氢气(气体)(492毫帕-千克-1)gt;绿色氢气(323 mPt-kg-1)。>;蓝氢(气体)(252 mPt-kg-1)。灰色氢气和蓝色氢气对环境的影响主要集中在气候变化、细颗粒物形成和化石燃料方面。绿色氢气的环境影响主要集中在气候变化、细颗粒物形成、化石燃料和矿产资源。碳足迹从大到小依次为:灰氢(煤)23.79千克-千克-1,用二氧化碳当量表示,下同);蓝色氢气(煤)(23.79千克-千克-1,用二氧化碳当量表示,下同)。>;蓝氢(煤)(11.07 kg-kg-1)>;灰色氢气(气体)(10.97千克-千克-1)>;蓝色氢气(气体)(3.47千克-千克-1)gt;绿色氢气(1.97 kg-kg-1)。灰色氢气和蓝色氢气生产过程中直接碳排放占比最大,而绿色氢气生产过程中直接碳排放占电力输入的比例较大。减少环境影响和碳排放的措施包括减少污染物和温室气体的直接排放、降低能耗、加强原材料替代和减量化。
