Abstract

Biohydrogen (Bio-H2) is widely recognized as a sustainable and environmentally friendly energy source, devoid of any detrimental impact on the environment. Lignocellulosic biomass (LB) is a readily accessible and plentiful source material that can be effectively employed as a cost-effective and sustainable substrate for Bio-H2 production. Despite the numerous challenges, the ongoing progress in LB pretreatment technology, microbial fermentation, and the integration of molecular biology techniques have the potential to enhance Bio-H2 productivity and yield. Consequently, this technology exhibits efficiency and the capacity to meet the future energy demands associated with the valorization of recalcitrant biomass. To date, several pretreatment approaches have been investigated in order to improve the digestibility of feedstock. Nevertheless, there has been a lack of comprehensive systematic studies examining the effectiveness of pretreatment methods in enhancing Bio-H2 production through dark fermentation. Additionally, there is a dearth of economic feasibility evaluations pertaining to this area of research. Thus, this review has conducted comparative studies on the technological and economic viability of current pretreatment methods. It has also examined the potential of these pretreatments in terms of carbon neutrality and circular economy principles. This review paves the way for a new opportunity to enhance Bio-H2 production with technological approaches.

利用难降解木质纤维素生物质提高生物制氢能力:最新进展、挑战和未来展望。
生物氢(BioH2)被广泛认为是一种可持续的环保能源,不会对环境造成任何有害影响。木质纤维素生物质(LB)是一种易于获取的丰富原料,可以有效地用作生产生物氢的成本效益高且可持续的基质。尽管面临诸多挑战,但枸杞预处理技术、微生物发酵和分子生物学技术的不断进步有可能提高 Bio-H2 的生产率和产量。因此,该技术不仅效率高,而且有能力满足与难分解生物质价值化相关的未来能源需求。迄今为止,已经对几种预处理方法进行了研究,以提高原料的消化率。然而,目前还缺乏全面系统的研究,来探讨预处理方法在通过黑暗发酵提高生物-H2 产量方面的有效性。此外,与这一研究领域相关的经济可行性评估也十分匮乏。因此,本综述对当前预处理方法的技术和经济可行性进行了比较研究。此外,它还从碳中和与循环经济原则的角度研究了这些预处理方法的潜力。本综述为利用技术方法提高生物-H2 产量提供了新的机遇。
