Description
Summary:► This article reviews state-of-the-art technology on bioH 2 production from lignocellulosic feedstock. ► This article discusses future development on integrated bioH 2 processes leading to high H 2 yield with waste reduction and CO 2 capture. ► This article provides useful information and critical comments on the current trend of bioH 2 research. Due to the recent energy crisis and rising concern over climate change, the development of clean alternative energy sources is of significant interest. Biohydrogen produced from cellulosic feedstock, such as second generation feedstock (lignocellulosic biomass) and third generation feedstock (carbohydrate-rich microalgae), is a promising candidate as a clean, CO 2-neutral, non-polluting and high efficiency energy carrier to meet the future needs. This article reviews state-of-the-art technology on lignocellulosic biohydrogen production in terms of feedstock pretreatment, saccharification strategy, and fermentation technology. Future developments of integrated biohydrogen processes leading to efficient waste reduction, low CO 2 emission and high overall hydrogen yield is discussed.
