Latest Clathrate hydrate Stories
Computer simulations revealing how methane and hydrogen pack into gas hydrates could enlighten alternative fuel production and carbon dioxide storage industries For some time, researchers have explored flammable ice for low-carbon or alternative fuel or as a place to store carbon dioxide. Now, a computer analysis of the ice and gas compound, known as a gas hydrate, reveals key details of its structure. The results show that hydrates can hold hydrogen at an optimal capacity of 5...
Rice researchers show ocean could have contained enough methane to cause drastic climate change The release of massive amounts of carbon from methane hydrate frozen under the seafloor 56 million years ago has been linked to the greatest change in global climate since a dinosaur-killing asteroid presumably hit Earth 9 million years earlier. New calculations by researchers at Rice University show that this long-controversial scenario is quite possible. Nobody knows for sure what started...
New study goes deeper in proving simple technique to pinpoint valuable energy source Their critics weren't convinced the first time, but Rice University researchers didn't give up on the "ice that burns." A paper by a Rice team expands upon previous research to locate and quantify the amount of methane hydrates -- a potentially vast source of energy -- that may be trapped under the seabed by analyzing shallow core samples. The paper published this week by the Journal of Geophysical...
Two scientists describe their research on the fate of massive methane releases from the Gulf oil spill during the summer and fall of 2010Methane, a potent greenhouse gas, seeps naturally from the seafloor in many places around the planet, including in the Gulf of Mexico.Scientists know that some of the Gulf's naturally released methane is eaten by microbes, but researchers are still trying to determine how much of this released methane ever reaches the atmosphere, where it may influence...
Researchers develop technique to measure methane gas from cattleMethane is an extremely potent greenhouse gas. Wetlands, gas hydrates, permafrost, termites, oceans, freshwater bodies, non-wetland soils, are all natural sources of atmospheric methane; however, the majority of methane presence ca n be accredited to human-related activities. These activities include: such as fossil fuel production, biomass burning, waste management and animal husbandry. The release of methane into the atmosphere...
Paper has implications for oxygen depletion, provides photographic evidence of plumesA new University of Georgia study that is the first to examine comprehensively the magnitude of hydrocarbon gases released during the Deepwater Horizon Gulf of Mexico oil discharge has found that up to 500,000 tons of gaseous hydrocarbons were emitted into the deep ocean. The authors conclude that such a large gas discharge"”which generated concentrations 75,000 times the norm"”could result in small-scale...
An unusual substance known as "dry water," which resembles powdered sugar, could provide a new way to absorb and store carbon dioxide, the major greenhouse gas that contributes to global warming, scientists reported August 25th at the 240th National Meeting of the American Chemical Society.The powder shows bright promise for a number of other uses, they said. It may, for instance, be a greener, more energy-efficient way of jumpstarting the chemical reactions used to make hundreds of...
The captain of one of two Russian-owned submarines said that the vessels would be able to cap the oil leak in the Gulf of Mexico. The captain was speaking as two of the subs started a campaign of exploration at the bottom of Lake Baikal in Siberia. He said that there was still time for the subs to help BP with the environmental disaster. The subs are searching for gas hydrates on the bed of Baikal. Hydrates are a potential alternative fuel source. Yevgenii Chernyaev told BBC News that the...
A series of newly discovered pits in the bottom of the Hudson Canyon, 100 miles southeast of New York Harbor, may be a key ingredient for the abundant and diverse marine ecosystem in and around the canyon, according to research by scientists from Rutgers University and the National Oceanic and Atmospheric Administration (NOAA).Peter Rona, professor of marine science at Rutgers' Institute of Marine and Coastal Sciences, and Vincent Guida, a research fisheries biologist at the NOAA Northeast...
Scientists from the Marine Biogeochemistry and Geology and Geophysics sections of the Naval Research Laboratory (NRL) organized and led a team of university and government scientists on an Arctic expedition to initiate methane hydrate exploration in the Beaufort Sea and determine the spatial variation of sediment contribution to Arctic climate change.Utilizing the U.S. Coast Guard Cutter Polar Sea as a research platform, three cross-shelf transects were surveyed and sampled off Alaska's North...
