Methane Production from Natural Gas Hydrates via Carbon Dioxide Fixation

Natural gas hydrate (NGH) is an ice like solid compound containing hydrocarbon that is present in marine and permafrost environments. Thermal stimulation, depressurization or a combination of both these methods are the approaches to recover natural gas. One innovative and promising solution to secure the future energy needs and mitigate carbon dioxide emissions simultaneously is to replace CH4 trapped in the gas hydrate deposits with carbon dioxide. In this short review, the state of the art experimental work in the CH4 production from natural gas hydrates via carbon dioxide fixation is summarized and future directions and challenges are highlighted.
