The depletion of fossil fuel reserves has resulted from their application in the industrial and energy sectors. As a result, substantial efforts have been dedicated to fostering the shift from fossil fuels to renewable energy sources via technological advancements in industrial processes. Microalgae can be used to produce biofuels such as biodiesel, hydrogen, and bioethanol. Microalgae are particularly suitable for hydrogen production due to their rapid growth rate, ability to thrive in diverse habitats, ability to resolve conflicts between fuel and food production, and capacity to capture and utilize atmospheric carbon dioxide. Therefore, microalgae-based biohydrogen production has attracted significant attention as a clean and sustainable fuel to achieve carbon neutrality and sustainability in nature. To this end, the review paper emphasizes recent information related to microalgae-based biohydrogen production, mechanisms of sustainable hydrogen production, factors affecting biohydrogen production by microalgae, bioreactor design and hydrogen production, advanced strategies to improve efficiency of biohydrogen production by microalgae, along with bottlenecks and perspectives to overcome the challenges. This review aims to collate advances and new knowledge emerged in recent years for microalgae-based biohydrogen production and promote the adoption of biohydrogen as an alternative to conventional hydrocarbon biofuels, thereby expediting the carbon neutrality target that is most advantageous to the environment.
化石燃料储量的枯竭是由于它们在工业和能源领域的应用。因此，人们做出了巨大的努力，通过工业过程中的技术进步，从化石燃料向可再生能源转变。微藻可用于生产生物燃料，如生物柴油、氢气和生物乙醇。由于微藻生长迅速、能够在各种生境中生长、能够解决燃料和粮食生产之间的冲突、以及能够捕获和利用大气中的二氧化碳，因此特别适合生产氢气。因此，基于微藻的生物制氢作为一种清洁可持续的燃料，吸引了人们的极大关注，以实现自然界的碳中和和可持续性。为此，本文强调了最近与基于微藻的生物制氢相关的信息，可持续制氢的机制，影响微藻生物制氢的因素，生物反应器设计和氢气生产，提高微藻生物制氢效率的先进策略，以及克服挑战的瓶颈和展望。本综述旨在整理近年来基于微藻的生物制氢方面的进展和新知识，促进生物制氢作为传统碳氢生物燃料的替代品，从而加快对环境最有利的碳中和目标。
