tippet from what I read I understand that methane hydrates are just frozen methane with 100% content of methane similar to dry ice - (frozen carbon dioxide). As to extraction cost is deposited on the sea floor and as to the US on the Atlantic shelf and in Gulf of Mexico. The main problem as I understand it is that by bringing the methane hydrate up it "melts" into methane gas and there the difficulty - no intermediate liquid stage. source at - netl.doe.gov marine.usgs.gov llnl.gov lpi.usra.edu gsfc.nasa.gov sps.esd.ornl.gov woodshole.er.usgs.gov Gas hydrates are stable at the temperatures and pressures that occur in ocean-floor sediments at water depths greater than about 500 meters, and at these pressures they are stable at temperatures above those for ice stability. Gas hydrates also are stable in association with permafrost in the polar regions, both in offshore and onshore sediments. Gas hydrates bind immense amounts of methane in sea-floor sediments. Hydrate is a gas concentrator; the breakdown of a unit volume of methane hydrate at a pressure of one atmosphere produces about 160 unit volumes of gas. The worldwide amount of methane in gas hydrates is considered to contain at least 1x104 gigatons of carbon in a very conservative estimate). This is about twice the amount of carbon held in all fossil fuels on earth. as to fuel cells methane is a very good feed gas for producing hydrogen, with pure carbon residual. Several fuel cell generators operating today have methane as imput fuel. One such company is in Danbury CT I think
