Abstract

Renewable energy demand is increasing globally. Fossil fuel source depletion and releasing of toxic gases into the environment further increase this response. Renewable energy is of different types; however gaseous biofuels are the promising option. Anaerobic digestion is a well know process for the production of gaseous biofuels. Among the gaseous biofuels, biohydrogen are recently the efficient and high energy yielding gaseous fuel. Therefore, this review article highlights the biohydrogen demand and utility. The review introduces different aspects of anaerobic digestion, dark fermentation, biohydrogen production, compositional of lignocellulosic biomass, factors influencing bioH2 yield, pre-treatment methods to improve hydrolysis and increasing bioH2 production, selection of robust microbial flora as an inoculum source for efficient bioH2 yield are also discussed. The paper highlights ideas and future plans to improve bioH2 production before gets implemented in industrial scale development.
