Biohydrogen (H) is an efficient form of renewable energy generated from various biological organisms. Specifically, primitive plants such as algae which are photosynthetic organisms can produce several commercial products, including biofuels due to their simple form, short life span, efficient photosynthetic capacity, and ability to grow in non-potable water sources. But these algae are often neglected and considered waste. Several studies have revealed the importance and role of algal species in generating biofuels, especially biohydrogen. Considerable research has been conducted in order to understand hydrogen production from algal sources. This review emphasizes the photolysis of water-based hydrogen production in algae apart from the metabolites fermentation process. The influence of physico-chemical factors, including oxygen scavengers, nanoparticles, and hydrogenases, was highlighted in this review to enhance H production from algal species. Also, several algal species used for hydrogen production are summarized in detail. Overall, this review intends to summarize the developments in hydrogen production from algal species keeping in view of excellent prospects. This knowledge certainly would provide a good opportunity for the industrial production of hydrogen using algal species, which is one of the most concerned areas in the energy sector.
生物氢（H₂）是由各种生物产生的一种高效可再生能源形式。具体而言，像藻类这样的原始植物作为光合生物，由于其形态简单、寿命短、光合能力强以及能够在非饮用水源中生长，能够生产多种商业产品，包括生物燃料。但这些藻类常常被忽视并被视为废物。多项研究揭示了藻类物种在生产生物燃料，尤其是生物氢方面的重要性和作用。为了了解从藻类来源制氢，人们已经开展了大量研究。本综述着重介绍了藻类中除代谢物发酵过程之外的基于水的光解制氢。本综述强调了物理化学因素，包括氧气清除剂、纳米颗粒和氢化酶对提高藻类物种产氢量的影响。此外，还详细总结了几种用于产氢的藻类物种。总体而言，本综述旨在鉴于良好前景总结藻类物种产氢的进展情况。这一知识无疑将为利用藻类物种进行工业化制氢提供一个好机会，而这是能源领域最受关注的领域之一。
