The goal of this work was to study the assessment of the life cycle of hydrogen production from biomass for transportation purposes concerning greenhouse gas emissions, emissions with an acidification potential and the fossil energy demand. As feedstocks woody biomass from forestry or short rotation coppice, herbaceous biomass (i.e., straw), energy crops (mainly maize and grain), bio-waste and organic by-products (e.g., glycerol) were considered and their potential in Germany assessed. The results showed that hydrogen produced from woody biomass emitted the least emissions due to the low emissions caused by the provision of the biomass. Regarding the cumulative fossil energy demand biomass from short rotation coppice showed the lowest values. The highest biomass potential for hydrogen production could be identified for woody biomass from forests as well as from short rotation coppice.
这项工作的目的是研究评估生物质制氢用于交通的生命周期，包括温室气体排放、酸化潜力排放和化石能源需求。作为原料，考虑了林业或短轮伐期的木质生物质、草本生物质（如秸秆）、能源作物（主要是玉米和谷物）、生物废物和有机副产品（如甘油），并评估了它们在德国的潜力。结果表明，由于生物质供应产生的低排放，木质生物质生产的氢气排放最少。就累积化石能源需求而言，短轮伐期的生物质显示出最低的数值。从森林和短轮伐期的木质生物质中可以获得生产氢气的最大生物质潜力。
