A method of creating a carbon dioxide hydrate is disclosed. The preferred steps include supplying liquid carbon dioxide and a dissociation agent to a hydrocarbon hydrate, decomposing the hydrocarbon hydrate by the dissociation agent into a hydrocarbon gas and liquid water, and forming the carbon dioxide hydrate from the liquid carbon dioxide and the liquid water. The dissociation agent preferably is at least one of an inorganic salt, a surface active agent, a hydrate inhibitor, and an absorption solution. Furthermore, a substance composition of liquid carbon dioxide and the dissociation agent is described, which is provided for depositing carbon dioxide hydrate in a subterranean geological formation. Furthermore, a deposition device is described, which is configured for depositing carbon dioxide hydrate in a subterranean geological formation.
