METHOD FOR PRODUCING AND USING HYDROGEN

摘要

PROBLEM TO BE SOLVED: To provide a new method for producing and using hydrogen which efficiently produces hydrogen by hydrogen fermentation using biomass as a raw material and reduces carbon dioxide discharged from the whole system.

SOLUTION: The method for producing and using hydrogen includes a hydrogen fermentation step for producing a biogas containing hydrogen and carbon dioxide by hydrogen fermentation using biomass as a raw material and a separation step for separating carbon dioxide from a gas derived from the biogas. Consequently, so-called carbon negative method is achieved.
