Abstract
The economy of an industrialized country is greatly dependent on fossil fuels. However, these non-renewable sources of energy are nearing the brink of extinction and which have caused serious adverse impacts on the environment. Hydrogen has emerged as a promising alternative and also has the highest calorific value. Bio-hythane is a hydrogen-methane blend can be produced from different organic substrates by two sequential anaerobic stages: a dark fermentation step followed by a second an anaerobic digestion step, for hydrogen and methane production, respectively. Bio-hythane is considered to be promising approach in sustainable energy sector. The advantages of two-stage technology include; high organic removal, high energy recovery and environment friendly. However, current efforts to recover bio-hythane energy from waste are still at bench scale level. The technical constraints in the fermentation must be removed for the indispensable bio-hythane recovery from waste. This short technical note highlights the two-stage fermentation and the technical barriers to be addressed for bio-hythane scale up from waste.
