Title:
METHOD FOR PRODUCING HYDROGEN IN GROUND, AND METHOD FOR PRODUCING METHANE IN GROUND
Document Type and Number:
WIPO Patent Application WO/2015/052806
Kind Code:
A1
Abstract:
Provided is a method for producing hydrogen in the ground, which has a simple constitution and enables the highly efficient proliferation of a hydrocarbon-utilizing hydrogen-producing bacterium, which occurs in the ground, to produce hydrogen steadily. Also provided is a method for producing methane utilizing the above-mentioned method for producing hydrogen in the ground. A method for producing hydrogen in the ground, which involves an activator injection step of injecting a hydrocarbon-utilizing hydrogen-producing bacterium activator into the ground. The hydrocarbon-utilizing hydrogen-producing bacterium activator is preferably an iron (III) ion. A method for producing methane in the ground, which involves a hydrogen production step of producing hydrogen by the above-mentioned method for producing hydrogen in the ground. The method also involves: a carbon dioxide injection step of injecting carbon dioxide into the ground; and a methane collection step of collecting methane, which is generated by the microbial conversion of hydrogen and carbon dioxide, from the ground.
