- China discovered ice in the South China Sea in 2007
- On March 28, a trial began where?16,000 cubic metres of gas was extracted daily
- Minister of Land and Resources said it was a breakthrough in energy use
The flammable ice was discovered in the South China Sea in 2007.
According to Chinese state run Xinhua, one cubic metre of combustible ice is equal to 164 cubic metres of natural regular gas.

Minister of Land and Resources Jiang Daming announced the success on May 18. The mining site was located in the Shenhu area of the South China Sea, 320 kilometres of the coast of Zhuhai City.
The trial mining started on March 28 ?at a depth of 4,153 feet. During the trial, around 16,000 cubic metres of gas was extracted each day.
The methane content was up to 99.5 percent of natural gas.

The Minister claimed that it was a major breakthrough that may lead to a global energy revolution.
The amount of predicted resources is equivalent to more than twice that of fossil fuels such as coal, oil and natural gas.

The flammable ice, a kind of natural gas hydrate was discovered in the South China Sea in 2007. ?For the past two decades China has been researching and exploring the area.
Combustible ice is found on the seabed. It can be ignited like solid ethanol. One cubic metre of combustible ice is equal to 164 cubic metres of regular natural gas.
Zhong Ziran, head of the China Geological Survey Bureau told Xinhua that combustible ice is more environmentally friendly than oil.
Qiu Haijun, director of the trial mining commanding headquarters told reporters: ‘With the advanced technology we could help resolve the energy resource problem and boost economic development and exchanges between countries.’
The US, Canada and Japan have also been researching into flammable gas. Earlier this month Japan announced it was successful at producing the natural gas on the pacific coast and will continue mining it for around three to four weeks, reports South China Morning Post.
WHAT IS FLAMMABLE ICE?

Flammable ice is made from methane and water.
It is formed when water and methane gas combine at temperatures below 10 degrees Celsius and pressures 30 times greater than normal atmospheric pressure.
The formation of the flammable ice requires a sufficiently high pressure and low temperature.
Most flammable ice is found at depths between 1,640 and 9,800 feet and is a white colour, close to that of normal water ice.
When it is released from the sea floor, the methane gas is then released and can then be ignited.
