A critical review on Biohydrogen generation from biomass

Global population growth and the exponential rise in energy consumption have put immense strain on finite fossil fuel supplies and presented a danger to the environment. Waste may be converted into energy using sustainable biological method. Biohydrogen generation from lignocellulosic materials is a clean as well as environmentally friendly path for producing biofuels with a bright future. The advancement of biohydrogen advanced technologies has resulted in the emergence of new power generation, which is important for the long-term utilization of power. Due to the limited energy needs and cost involved, biohydrogen production has many benefits over photo-electrochemical or thermo-chemical methods. Although beneficial and favored, the hydrogen production from biomass and carbohydrate raw material has always been at the lab scale. The main aim of the article was to review the various biomass and biohydrogen from biomass. This paper also goes over the various methods for producing biohydrogen, including dark fermentation, photo-fermentation, combined dark and photo fermentation, bio-photolysis, and microbial electrolysis cells. Each form of production's methods, benefits and drawthe existing research, nanoparticles can play an essential role in strengthening this process in a sustainable basis, allowing for significant yields of biohydrogen to be achieved on a feasible scale. Due to this topic is still in its initial stages, further research is required to close the current gap in terms of practical applications and commercial viability.(c) 2022 Hydrogen Energy Publications LLC.
