China discovers combustible ice in land-based regions
China has successfully excavated combustible ice, a kind of natural gas hydrate, in permanent tundra in the south margin of the country’s northwestern Qilian Mountains, the Ministry of Land and Resources said Friday.
Samples of combustible ice were collected in the area in November 2008, making China the first country to collect the gas hydrate in tundra in the medium and low latitudes, according to the ministry. It also shows that China has become the third country successfully excavating gas hydrate from a land-based area in the world after Canada and the United States, the ministry said. Preliminary research shows that the prospective volume of natural gas hydrate in the country's frozen earth regions is estimated to reach 35 billion tonnes of oil equivalent. China successfully excavated combustible ice from below the floor of the South China Sea in May 2007.
Combustible ice has been found in high altitude frozen plateaus as well as underwater in marine sediments. Natural gas hydrates are essentially just frozen methane and water and can literally be lit on fire bringing a whole new meaning to fire and ice. Researchers still need to get a better understanding of how best to handle the fuel, for it to be commercially exploited. The US DOE is looking into it as well and researchers expect that the hydrate will have to go through a phase change and melt it into methane and water before it can be efficiently combusted. If left to melt on its own as the earth warms though, methane could be released into the atmosphere, and it could cause even more damage than if it were just burned.
One cubic meter of combustible ice contains 164 cubic meters of regular natural gas and is considered to have few impurities, meaning it can burn cleaner with less pollutants. While reserves of combustible ice have been found around the world, China’s discovery is big and estimates say that there is enough energy frozen in the tundra to provide the country with energy for 90 years. Natural gas, which is not a zero emission fuel, can only be considered a “cleaner” energy source compared to oil, but given the alternative of it just being released from melting, it might be wise to continue research on this new energy source.
