Extensive effort is being made to explore renewable energy in replacing fossil fuels. Biohydrogen is a promising future fuel because of its clean and high energy content. A challenging issue in establishing hydrogen economy is sustainability. Biohydrogen has the potential for renewable biofuel, and could replace current hydrogen production through fossil fuel thermo-chemical processes. A promising source of biohydrogen is conversion from algal biomass, which is abundant, clean and renewable. Unlike other well-developed biofuels such as bioethanol and biodiesel, production of hydrogen from algal biomass is still in the early stage of development. There are a variety of technologies for algal hydrogen production, and some laboratory- and pilot-scale systems have demonstrated a good potential for full-scale implementation. This work presents an elucidation on development in biohydrogen encompassing biological pathways, bioreactor designs and operation and techno-economic evaluation. Challenges and prospects of biohydrogen production are also outlined.
正在大力探索可再生能源以替代化石燃料。由于生物氢具有清洁和高能量含量，因此是一种很有前途的未来燃料。建立氢能经济的一个具有挑战性的问题是可持续性。生物氢具有可再生生物燃料的潜力，并可能通过化石燃料热化学过程取代当前的氢气生产。生物氢的一个很有前途的来源是从藻类生物质转化而来，藻类生物质丰富、清洁且可再生。与生物乙醇和生物柴油等其他发达的生物燃料不同，从藻类生物质生产氢气仍处于发展的早期阶段。藻类制氢有多种技术，一些实验室和中试系统已经证明了在大规模实施方面具有很好的潜力。本文阐述了涵盖生物途径、生物反应器设计和操作以及技术经济评估的生物氢开发情况。还概述了生物制氢的挑战和前景。
