Abstract
Biohydrogen is the cleanest form of renewable energy. It can be produced by thermochemical and biological processes from agro-industry biomass. Production of biohydrogen from agro-industry waste has the double advantage of reducing waste biomass together with greenhouse gas emissions. Biological processes for biohydrogen production are limited due to a lower yield of hydrogen from agro-industry waste. Various factors such as feedstock content, nutrients, pH, temperature, hydraulic retention time (HRT), and hydrogen partial pressure (HPP) affects the yield of biohydrogen. Various reactor configurations have been devised to enhance the biohydrogen yield. The integration of changing the reactor configurations accompanied with other reactor processes has been noticed as a promising pathway for biological hydrogen production. Reactor configurations of microbial fuel cell and dark fermentation show the great potential of biohydrogen enhancement from agro-industry waste. The bulk generation of agro-industry waste driven by a growing population is an opportunity for green hydrogen production and promotes a circular bioeconomy.
