Abstract
COintroduced into the ground reacts with water in the moisture present in the surroundings to convert to hydrocarbon, suppressing leakage of COabove ground. The method for producing hydrocarbon has an introduction step for introducing COinto a storage site in the ground where moisture and a catalytic metal are present, the pressure is 5 MPa or higher, and the temperature is 40° C. or higher, to bring the COinto a subcritical state or a supercritical state, and a synthesis step for reacting the water in the moisture with the subcritical or supercritical COin the storage site to synthesize hydrocarbon. The storage site is preferably a site from 800 m to 1200 m below ground. The pressure of the storage site is preferably 8 MPa or higher.
