China’s combustible ice estimated at 80 bn tonnes

Beijing, June 2 (IANS) China is estimated to have 80 billion tonnes of an oil equivalent known as "combustible ice", the Ministry of Land and Resources said Friday.

Li Jinfa, Deputy Director of the China Geological Survey, made the statement at a press conference on China's first success in mining combustible ice at sea, Xinhua news agency reported.

Beijing announced its success on May 18 in collecting samples of combustible ice in the South China Sea after nearly two decades of research and exploration, a major breakthrough that may lead to a global energy revolution.

Combustible ice usually exists in seabed or tundra areas, which have the strong pressure and low temperature necessary for its stability. It is flammable like solid ethanol.

One cubic metre of combustible ice, a natural gas hydrate, is equal to 164 cubic metres of regular natural gas. International scientific circles have predicted that the natural gas hydrate is the best replacement for oil and natural gas.

"So far, trial mining of combustible ice in the Shenhu sea, about 320 km southeast of Zhuhai city in Guangdong, has made smooth progress with an average of 8,350 cubic metres of gas with high purity extracted each day," Li said.

He said China would accelerate the exploration of potential combustible ice reserves, launch trial mining of different types of combustible ice, and continue to strengthen marine science and technology innovation.

"In addition, China will make environment protection a top priority during the trial mining and strive to achieve green exploration and exploitation."
