Featuring high caloric value, clean-burning, and renewability, hydrogen is a fuel believed to be able to change energy structure worldwide. Biohydrogen production technologies effectively utilize waste biomass resources and produce high-purity hydrogen. Improvements have been made in the biohydrogen production process in recent years. However, there is a lack of operational data and sustainability analysis from pilot plants to provide a reference for commercial operations. In this report, based on spectrum coupling, thermal effect, and multiphase flow properties of hydrogen production, continuous pilot-scale biohydrogen production systems (dark and photo-fermentation) are established as a research subject. Then, pilot-scale hydrogen production systems are assessed in terms of sustainability. The system being evaluated, consumes 171,530 MJ of energy and emits 9.37 t of CO eq when producing 1 t H, and has a payback period of 6.86 years. Our analysis also suggests future pathways towards effective biohydrogen production technology development and real-world implementation.
氢能具有高热量值、清洁燃烧和可再生性，被认为是能够改变全球能源结构的燃料。生物制氢技术有效地利用了废生物质资源，并生产出高纯度的氢气。近年来，生物制氢工艺得到了改进。然而，从试点工厂缺乏运行数据和可持续性分析，无法为商业运营提供参考。在本报告中，基于制氢的光谱耦合、热效应和多相流特性，建立了连续中试规模生物制氢系统（暗发酵和光发酵）作为研究课题。然后，从可持续性的角度对中试规模制氢系统进行评估。评估系统在生产 1 吨氢气时消耗 171530MJ 的能量，排放 9.37 吨 CO eq ，投资回收期为 6.86 年。我们的分析还提出了未来发展有效生物制氢技术和实际应用的途径。
