Methane hydrates have been known about for years, but cost and technical difficulties have so far been barriers to exploiting them on any kind of scale. Claims that they could ‘flood the atmosphere with climate-changing greenhouse gases’ are the usual over-the-top propaganda.

Commercial development of the globe’s huge reserves of a frozen fossil fuel known as “combustible ice” has moved closer to reality after Japan and China successfully extracted the material from the seafloor off their coastlines, says Phys.org.

But experts said Friday that large-scale production remains many years away—and if not done properly could flood the atmosphere with climate-changing greenhouse gases.

Combustible ice is a frozen mixture of water and concentrated natural gas. Technically known as methane hydrate, it can be lit on fire in its frozen state and is believed to comprise one of the world’s most abundant fossil fuels.


The official Chinese news agency Xinhua reported that the fuel was successfully mined by a drilling rig operating in the South China Sea on Thursday. Chinese Minister of Land and Resources Jiang Daming declared the event a breakthrough moment heralding a potential “global energy revolution.”

A drilling crew in Japan reported a similar successful operation two weeks earlier, on May 4 offshore the Shima Peninsula.For Japan, methane hydrate offers the chance to reduce its heavy reliance of imported fuels if it can tap into reserves off its coastline.

In China, it could serve as a cleaner substitute for coal-burning power plants and steel factories that have polluted much of the country with lung-damaging smog.
. . .
Estimates of worldwide reserves range from 280 trillion cubic meters (10,000 trillion cubic feet) up to 2,800 trillion cubic meters (100,000 trillion cubic feet), according to the U.S. Energy Information Administration. By comparison, total worldwide production of natural gas was 3.5 billion cubic meters (124 billion cubic feet) in 2015, the most recent year available.

That means methane hydrate reserves could meet global gas demands for 80 to 800 years at current consumption rates.
