ABSTRACT:

Nowadays, energy is the basic need for social life. Bioenergy is the powerful renewable substitution of fossil fuels. Hydrogen is a clean fluid that can be easily provided with the help of certain biomass. Hydrogen production can be produced by various techniques such as electrolysis, steam-methane reforming process, and biological process. The majority of the countries produced biohydrogen as bioenergy because it is carbon-free fuel and it is eco-friendly and it does not contribute to ozone depletion or greenhouse emissions. Waste (sewage water, industrial waste, domestic waste) can be used as an alternative source. Hydrogen production from the various biological process, such as dark fermentation some of the bacteria (Enterobacter and clostridium) involved in hydrogen production are yield very high energy. In this article, we can discuss the advanced techniques, parameters affecting biohydrogen production during the fermentation process, limitations, and importance.
