Methane hydrates could become energy source
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 be substantial in size, was found about 15 miles off the coast at a depth of about 2,600 feet, at the summit of an undersea mud volcano.
Scientists were conducting an unrelated study when they came across the volcano, which sits on top of an active fault zone in the Santa Monica Basin.
