Overcoming the existing environmental issues and the gradual depletion of energy sources is a priority at global level, biohydrogen can provide a sustainable and reliable energy reserve. However, the process instability and low biohydrogen yields are still hindering the adoption of biohydrogen production plants at industrial scale. In this context, membrane-based biohydrogen production technologies, and in particular fermentative membrane bioreactors (MBRs) and microbial electrolysis cells (MECs), as well as downstream membrane-based technologies such as electrodialysis (ED), are suitable options to achieve high-rate biohydrogen production. We have shed the light on the research efforts towards the development of membrane-based technologies for biohydrogen production from organic waste, with special emphasis to the reactor design and materials. Besides, techno-economic analyses have been traced to ensure the suitability of such technologies in bio-H production. Operation parameters such as pH, temperature and organic loading rate affect the performance of MBRs. MEC and ED technologies also are highly affected by the chemistry of the membrane used and anode material as well as the operation parameters. The limitations and future directions for application of membrane-based biohydrogen production technologies have been individuated. At the end, this review helps in the critical understanding of deploying membrane-based technologies for biohydrogen production, thereby encouraging future outcomes for a sustainable biohydrogen economy.
克服现有的环境问题和能源的逐渐枯竭是全球优先事项，生物氢可以提供可持续和可靠的能源储备。然而，工艺不稳定和低生物氢产率仍然阻碍了生物制氢工厂在工业规模上的采用。在这种情况下，基于膜的生物制氢技术，特别是发酵膜生物反应器（MBR）和微生物电解池（MEC），以及下游基于膜的技术，如电渗析（ED），是实现高生物氢产率的合适选择。我们已经研究了开发基于膜的技术从有机废物生产生物氢的研究工作，特别强调了反应器设计和材料。此外，还进行了技术经济分析，以确保这些技术在生物-H 生产中的适用性。操作参数，如 pH 值、温度和有机负荷率，会影响 MBR 的性能。MEC 和 ED 技术也受到所用膜的化学性质和阳极材料以及操作参数的高度影响。已经确定了基于膜的生物制氢技术应用的局限性和未来方向。最后，这篇综述有助于深入了解基于膜的技术在生物制氢中的应用，从而鼓励未来实现可持续的生物氢经济。
