Methane hydrate is an ice-like solid material and it has a structure which water molecules enclose gas molecules. For low temperature and high pressure, hydrocarbon gas forms hydrate and due to this condition, it is existed in the arctic region or deep sea. Presently, the amount of methane hydrate is unpredictable, but it is assumed that the amount will be enormous. For this reason, it is expected that it will play a major role as natural gas resources in the future. However, the production technologies are stayed on the low level and the economical technology was not developed yet. Also, emission of natural gas from methane hydrate will cause global warming and thus it is considered as a critical environmental problem. In this paper, the state of the art of the production technologies and environmental effects of methane hydrate were summarized.
