Biohydrogen is a clean and renewable source of energy. It can be produced by using technologies similar as thermochemical, electrolysis, print electrochemical and natural etc. Among these technologies, the natural system (dark fermentation) is considered more sustainable and ecofriendly. Dark turmoil involves anaerobic microbes which degrade carbohydrate rich substrate and produce hydrogen. Lignocellulose biomass is an abundantly available raw material and can be employed as profitable and renewable substrate for biohydrogen product. Although there are numerous hurdles, nonstop advancements in lignocellulose biomass pretreatment technology, microbial fermentation (mixed substrate and co-culture fermentation), the involvement of molecular biology ways, and understanding of colorful factors (pH, T, addition of nanomaterial’s) effect on biohydrogen productivity and yield render this technology effective and able to meet unborn energy demands. Farther integration of biohydrogen product technology with other products similar as bio-alcohol, Unpredictable adipose acids and methane have the eventuality to ameliorate the effectiveness and economics of the overall process. In this composition, colorful styles used for lignocellulose biomass pretreatment, technologies in trends to produce and ameliorate biohydrogen product, a coproduction of other energy coffers, and techno- profitable analysis of biohydrogen Product from lignocellulose biomass are reviewed.
