Biohydrogen has the potential to replace current hydrogen production technologies relying heavily on fossil fuels through electricity generation. While biohydrogen research is still immature, extensive work on laboratory- and pilot-scale systems with promising prospects has been reported. This work presents a review of advances in biohydrogen production focusing on production pathways, microbiology, as well as bioreactor configuration and operation. Challenges and prospects of biohydrogen production are also outlined. ? 2012, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.
