Abstract
Hydrogen is a promising future fuel because of its clean and high-energy content properties. It is an ideal energy carrier to reduce greenhouse gas emissions because its conversion to energy yields only pure water. A challenging issue in establishing hydrogen as a source of energy for the future is the way it is produced. Biohydrogen produced from biological processes has the potential for renewable biofuel to replace current unsustainable hydrogen production technologies, which rely on nonrenewable fossil fuels through thermochemical processes. One of the promising biohydrogen production approaches is conversion from microalgae, which is abundant, clean, and renewable. Unlike other well-developed biofuels such as bioethanol and biodiesel, algal hydrogen production is still in the early stage of development. This review examines the perspectives and state-of-the-art of algal hydrogen research in the context of pathways of hydrogen production, bioreactor design and operation, and economic evaluation. Prospects and challenges in algal hydrogen production are also outlined. ? 2014 Elsevier B.V. All rights reserved.
