Hydrogen has become a research highlight by virtue of its clean energy production technology and high energy content. The technology of biohydrogen production from biological waste via fermentation has lower costs, provides environment-friendly methods regarding energy balance, and creates a pathway for sustainable utilization of massive agricultural waste. However, biohydrogen production is generally limited by lower productivity. Many studies have been conducted aimed at improving biohydrogen production efficiency. Hence, this review is intended to describe improving routes for biohydrogen production from agricultural waste and highlights recent advances in these approaches. In addition, the critical factors affecting biohydrogen production, including the pretreatment method, substrate resource, fermentation conditions, and bioreactor design, were also comprehensively discussed along with challenges and future prospects.
氢能因其清洁能源生产技术和高能量含量而成为研究热点。通过发酵从生物废物中生产生物氢能的技术成本较低,在能源平衡方面提供了环保方法,并为大规模农业废物的可持续利用创造了途径。然而,生物制氢的生产力普遍较低。许多研究旨在提高生物制氢的效率。因此,本综述旨在描述从农业废物中提高生物制氢效率的途径,并重点介绍这些方法的最新进展。此外,还全面讨论了影响生物制氢的关键因素,包括预处理方法、底物资源、发酵条件和生物反应器设计,并探讨了挑战和未来前景。
