A World First:<br />
Japan says it has extracted gas from offshore<br />
deposits of methane hydrate - sometimes called<br />
''flammable ice'' - a breakthrough that officials<br />
say could be a step towards tapping a promising<br />
but still little-understood energy source.<br />
The gas, whose extraction from the undersea hydrate<br />
reservoir is thought to be a world first, could provide<br />
an alternative source of energy to known oil and gas<br />
reserves. That could be crucial for Japan, which is<br />
the world's biggest importer of liquefied natural gas<br />
and is engaged in a public debate about whether<br />
to resume its heavy reliance on nuclear power.<br />

Extracts<br />
Methane<br />
Hydrate Gas<br />
Experts estimate the carbon found in gas hydrates<br />
worldwide totals at least twice the amount of<br />
carbon in all of the earth's other fossil fuels, making<br />
it a potential game-changer for energy-poor<br />
countries such as Japan. Researchers had already<br />
extracted gas from onshore methane hydrate<br />
reservoirs but not from beneath the seabed.<br />
Methane is a greenhouse gas, and the exact properties<br />
of undersea hydrates and how they might affect<br />
the environment are poorly understood. Japan has<br />
invested hundreds of millions of dollars to explore<br />
offshore methane hydrate reserves in the Pacific and<br />
the Sea of Japan. That task has become all the more<br />
pressing after the Fukushima nuclear crisis, which has<br />
all but halted Japan's nuclear energy program and<br />
caused a sharp increase in fossil fuel imports. Japan's<br />
rising energy bill has weighed heavily on its economy,<br />
helping to push it to a trade deficit and reducing the<br />
benefits of a weaker yen to Japanese exporters.<br />
