"China is speeding up its pace in natural gas hydrate exploration and utilization," said Che Changbo, deputy director of the geological exploration department under the Ministry of Land and Resources.
"Commercial production of the resource will begin in China's tundra around 2020, and underwater around 2030," Che said, adding commercial production will help ease the country's dependence on oil and coal.
Besides China, many countries, including Canada, Japan, US and Norway, are accelerating preparation for commercial production of natural gas hydrates.
A Japanese energy company announced in February it had extracted natural gas from offshore flammable ice deposits, becoming the first in the world to do so, and expected to achieve commercial production within six years.
"It means commercial production of flammable ice is feasible," said Zhang Haiqi, chief scientist with the China Geological Survey.
Scientists say natural gas hydrates exist under hundreds of meters of sedimentary stone under the sea or in tundra, from about 200 to 2,000 meters underground.
Promising reserves of the resource have been detected at the bottom of many of the world's seas and oceans, including the South China Sea, the Arctic Ocean, the Indian Ocean, and waters surrounding Antarctica and Australia.
China started flammable ice research in 1995 and the country collected its first natural gas hydrate samples in the South China Sea in 2007, making China the fourth country to confirm such underwater findings, after the United States, Japan and India.
