Recently, the employment of sustainable energy origins for generating biohydrogen has gained … Status: Completed PDF version Investigators. Feed Stock for Biohydrogen Production Glucose is the ideal substrate, but it is too costly at present. Dark fermentation has become one of the well-known technologies for biohydrogen production, which enables the microorganisms to produce H 2 in a dark anaerobic condition [].However, with the formation of many by-products, the low H 2 yield on substrates is a major disadvantage. Buitrón G(1), Prato-Garcia D(1), Zhang A(1). Of course, it is too premature to be able to exactly define what might be a practical level for biohydrogen production, but a rough State of the Art and Progress in Production of Biohydrogen. However, overall process efficien-cies and hydrogen production rates have previously been low. of biohydrogen production from lignocellulosic biomass and its sustainability on the basis of a life cycle assessment (LCA). production and discusses the drivers behind design choices.
