Fifty-five million years ago the world's climate was catastrophically changed when volcanoes melted natural gas frozen in the seabed. Now Japan plans to drill for the same icy crystals to end its reliance on imported energy. Billions of tons of methane hydrate, frozen chunks of chemical-laced water buried in sediment some 3,000 feet under the Pacific Ocean floor, may help Japan win energy independence from the Middle East and Indonesia.
Japanese engineers have found enough "flammable ice" to meet its gas use demands for 14 years. The trick is extracting it without damaging the environment. Japan is joining the U.S. and Canada in test drilling for methane even as scientists express concerns about any uncontrolled release of the frozen chemical. Some researchers blame the greenhouse gas for triggering a global firestorm that helped wipe out the dinosaurs.
"Methane hydrate was a key cause of the global warming that led to one of the largest extinctions in the earth's history," says Ryo Matsumoto, a University of Tokyo scientist who has studied frozen gas since 1987. . . Read more from BLOOMBERG
