Summary:

There is a large amount of combustible ice for high-quality energy that is efficient, clean, and low-carbon, and has been seen a potential alternative energy source for the future. There is a nearly 50-year history of the development of combustible ice in foreign countries. In 2012, the US succeeded in replacing methane with carbon dioxide on the continental slope of Alaska and, a year later, Japan managed to exploit combustible ice in a trough of its southern sea area. And then major countries with combustible ice began paying greater attention to the exploitation of this resource. But, even though China made a breakthrough in exploitation in the South China Sea, in 2013, it encountered many problems in its backward technology and laws and regulations. Major countries with combustible ice have placed more importance on combustible ice exploitation, by improving laws and regulations, formulating development plans, doing R&D on key technologies, and increasing support and government investment, giving them valuable experience, which China could learn from.
