Biohythane is a gas mixture consisting of approximately 5-10 percent
hydrogen, 50-65 percent methane and 30-40 percent carbon dioxide that can
be produced by a two-stage anaerobic digestion process: a dark fermentation
for the production of hydrogen as a first step, followed by a second step,

anaerobic digestion for the production of methane. The advantages of biohythane
include a high combustion efficiency, can be generated from biomass and
environmentally friendly. This paper discussed the biohythane production
process, the factors affecting the production of biohythane, the limitations

and use of biohythane, as well as the challenges of biohythane production in
Thailand with a focus on the production of biohythane from agricultural
biomass. These were presented in order to demonstrate the capacity to
produce renewable energy using biomass in Thailand in line with the growth

of the Bio-Circular-Green Economy (BCG Economy) to achieve Thailand
Economy 4.0.
