采用新型连续混合固定化污泥反应器，对糖蜜暗发酵制氢进行了技术经济分析。假设制氢厂建在杭州，使用寿命为10年。还考察了工作容积(10~50亿m~3)对制氢装置经济效益的影响。利用Super-Pro Designer对生物过程的质量和能量平衡进行了模拟。投资回报率从−的37.2%提高到47.3%，规模从1000万立方米增加到50亿立方米。只有40亿立方米和50亿立方米的规模才能获得正效益，回收期分别为9.7年和6.9年。40亿立方米和50亿立方米规模的内部收益率分别为0.63%和9.25%，这意味着规模较大(50亿立方米)的制氢装置在经济上更可行。
The techno-economic analysis of dark fermentative hydrogen production from molasses in a novel continuous mixed immobilized sludge reactor was performed. The hydrogen-producing plant was assumed to be built in Hangzhou with lifetime of 10 years. The effect of the working volume (10–50 m3) on the economic performance of hydrogen-producing plant was also investigated. The mass and energy balance of the bioprocess was simulated using Super-Pro Designer. The return on investments increased from −37.2% to 47.3% with scales increasing from 10 m3to 50 m3. Only the scales of 40 m3and 50 m3could get positive benefits with payback periods of 9.7 years and 6.9 years, respectively. The internal rate of return of scales of 40 m3and 50 m3were 0.63% and 9.25%, respectively, which meant the hydrogen-producing plant with higher scale (50 m3) would be more economically feasible.
