Current Situation of Gas Hydrates Resarch and Challenges for Future

Natural gas hydrate as a potential natural fuel resource, which occur worldwide in the polar regions, mostly associated with onshore and offshore permafrost, and in sediment of out continental and insular margins will provide human enormous energy in the coming 21 century. Three aspects of gas hydrates are important: their fossil fuel resource potential, their role as a submarine geologic hazard and their effects on global climate change. Gas hydrates have become the focus of intense international interest over the past few years because of their abundance and their potential role as a fuel, which could mitigate global climate change. Natural gas hydrate future face to challenges.
