  • Method for producing natural gas from hydrocarbon hydrates while simultaneously storing carbon dioxide in geological formations
    Patent number: 8590619
    Abstract: The invention relates to a method for extracting methane from methane hydrates, comprising the following steps: feeding carbon dioxide to the methane hydrate deposits; allowing the carbon dioxide to take effect on the methane hydrate to release methane and store the carbon dioxide as carbon dioxide hydrate; and removing the released methane, characterized in that the fed carbon dioxide is supercritical carbon dioxide.
