Abstract :
[en] Hydrogen (H2) is being considered as an ideal and clean energy carrier since the utilization of hydrogen, either via combustion or via fuel cells, results in pure water. However, currently its production relies mainly (i.e. 95%) on fossil fuels. The recent advances to produce biohydrogen from renewable sources such as biomass and particularly by fermentation of carbohydrate-rich substrates from agriculture and agro-industries appear promising. Such a process called “dark fermentation” enables both organic waste treatment and renewable energy production to be coupled. The soluble metabolites, mainly acetate and butyrate, contained in the spent medium of the dark fermentation bioreactor may be efficiently converted to methane in a second anaerobic digester treating other carbon sources. The paper reviews the state-of-the art on the challenges and prospective applications of dark fermentation as a first step of anaerobic digestion of municipal solid wastes to produce H2 and CH4.
