    The gas age is good news Published on Saturday, March 16, 2013, updated Saturday, March 16, 2013 Methane hydrate joins shale gas and deep sea gas I have the following article in the Times on 15 March:   Move over shale gas, here comes methane hydrate. (Perhaps.) On Tuesday the Japanese government’s drilling ship Chikyu started flaring off gas from a hole drilled into a solid deposit of methane and ice, 300 metres beneath the seabed under 1000 metres of water, 30 miles off the Japanese coast.   The real significance of this gas flare probably lies decades in...

    The news in early March that a Japanese company had finally successfully extracted natural gas from methane hydrate deposits under the seabed offshore Japan was hailed as a breakthrough for the energy industry around the world. There are large deposits of methane hydrate, or "ice gas", in several locations around the planet which means, if successfully exploited, they could bring to many regions around the world the low gas prices currently seen in North America as a result of the shale gas boom. Japan Oil, Gas and Metals National Corporation (JOGMEC) reported March 12 that it successfully extracted natural gas...
  • Obama administration moves ahead with sweeping rules requiring cleaner gasoline

    The Environmental Protection Agency will move ahead Friday with rules requiring cleaner gasoline and cars nationwide, despite fierce protests from the oil industry and some conservative Democrats, according to several individuals briefed on the matter. The proposed rules — which had been stuck in regulatory limbo since December 2011 in the face of intense political opposition — would cut the amount of sulfur in U.S. gasoline by two-thirds and impose fleetwide pollution limits on new vehicles by 2017. The regulation enjoys support from auto companies, state regulators, environmental groups and equipment manufacturers. But oil industry officials and their congressional allies...

    A changing Gulf Stream is warming deep waters along the eastern United States and destabilizing greenhouse gases trapped in sediments. Somewhere off the eastern coast of North Carolina, a frozen mixture of water and methane gas tucked in seabed sediments is starting to break down. Researchers blame a shifting Gulf Stream — the swift Atlantic Ocean current that flows north from the Gulf of Mexico — which is now delivering warmer waters to areas that had previously only experienced colder temperatures. “We know methane hydrates exist here and, if warming continues, it can potentially lead to less stable sediments in...
  • Natural gas supplies could be augmented with methane hydrate

    WASHINGTON – Naturally occurring methane hydrate may represent an enormous source of methane, the main component of natural gas, and could ultimately augment conventional natural gas supplies, says a new congressionally mandated report from the National Research Council. Although a number of challenges require attention before commercial production can be realized, no technical challenges have been identified as insurmountable. Moreover, the U.S. Department of Energy's Methane Hydrate Research and Development Program has made considerable progress in the past five years toward understanding and developing methane hydrate as a possible energy resource. "DOE's program and programs in the national and international...
  • Methane Bubbling Up From Undersea Permafrost?

    The East Siberian Sea is bubbling with methane, a powerful greenhouse gas, being released from underwater reserves, according to a recent expedition. This could be a sign that global warming is thawing underwater permafrost, which is releasing methane that has been locked away for many thousands of years. If these methane emissions from the Arctic speed up, it could cause "really serious climate consequences," said expedition member Igor Semiletov of the University of Alaska, Fairbanks. According to our data, more than 50 percent of the Arctic Siberian shelf is serving as a source of methane to the atmosphere," Semiletov said....

    Researchers have found alarming evidence that the frozen Arctic floor has started to thaw and release long-stored methane gas. The results could be a catastrophic warming of the earth, since methane is a far more potent greenhouse gas than carbon dioxide. But can the methane also be used as fuel? AP It's always been a disturbing what-if scenario for climate researchers: Gas hydrates -- hard clumps of ice and methane, conserved by freezing temperatures and high pressure -- could grow unstable and release massive amounts of methane into the atmosphere. Since methane is a potent greenhouse gas, the result would...
  • Taiwan discovers frozen natural gas off southwest coast

    Taiwan has found off its coast huge deposits of frozen natural gas, known as the "ice that burns" and billed as the energy source of the future, a newspaper said yesterday. Taiwanese and Japanese researchers succeeded in extracting samples of methane hydrate from the ocean floor off Taiwan's southwest coast and will publish their report in May, the Chinese-language Liberty Times (the Taipei Times' sister newspaper) reported. The team began its exploration two years ago, after US and Japanese scientists suspected methane hydrate deposits in the region through monitoring by satellite and scientific equipment. Relying on a deep-sea remote-controlled research...

    BP teamed with government agencies to drill an exploratory well this month that could help unlock a fabulous new supply of North Slope natural gas. The well probed a layer of material just beneath the permafrost, called gas hydrate. The hydrate is a solid, crystalline form of gas, usually methane, mixed in sandstone and water. A combination of cold and pressure keeps the gas as a solid. Hydrates exist in many locations around the world, including under seabeds. On the North Slope, government geologists estimate there are 450 trillion cubic feet of gas hydrate. That's a staggering volume -- more...

    AP SCIENCE WRITER LOS ANGELES -- Scientists have discovered an undersea deposit of frozen methane just off the Southern California coast, but whether it can be harnessed as a potential energy source is unknown. In recent years, there has been a growing interest in tapping methane hydrates, ice-like crystals that form at low temperatures and high pressure in seabeds and in Arctic permafrost. Scientists estimate that the methane trapped in previously known frozen reservoirs around the globe could power the world for centuries. But finding the technology to mine such deposits has proved elusive. The newly discovered deposit, believed to...
