New method could unlock vast stores of methane
In a reported world first, Japan extracted natural gas from methane hydrate, considered a next-generation energy source, in the Pacific seabed off Aichi Prefecture, the Ministry of Economy, Trade and Industry said.
“We started production of a certain amount of methane gas from around 9:30 a.m.,” a ministry official said, noting that if the gas can be extracted without any problems for about two weeks in the ongoing trial, it will be a “major step” toward future commercial development of the resource.

Japan Oil, Gas and Metals National Corp. (Jogmec) and the National Institute of Advanced Industrial Science and Technology used a method to decrease pressure of layers bearing methane hydrate to dissociate the solid substance.
