Dark fermentation for hydrogen production
WebAug 19, 2024 · Biological hydrogen production from renewable biomass or waste materials by dark fermentation is a promising alternative to conventional routes since it is energy-saving and reduces environmental pollution. However, the current yield and evolution rate of fermentative hydrogen production are still low. WebMar 5, 2024 · Dark fermentation is more attractive than the other biological processes, due to the low demand for light (unlike the photosynthetic routes), capable of high biohydrogen production rate, environmentally friendly, versatile substrate utilisation and less energy intensive (Ghimire et al. 2015; Mishra et al. 2024 ).
