The Canadian and Japanese team will describe how they got the hydrates to release gas, like bubbles out of champagne. In a world first, the team got a production well to generate a steady flow of gas for six days, fuelling a flame in the Arctic darkness.

“The message is quite clear, you can produce gas hydrates using conventional techniques,” says Scott Dallimore, a senior scientist at Natural Resources Canada, who co-led the project in the Mackenzie Delta. Over two winters the researchers drilled down more than a kilometre into a 150-metre-thick layer on the edge of the Beaufort Sea at Mallik — the most concentrated known deposit of the frozen fuel in the world.
