ANCHORAGE, AK (AP) - Researchers are looking into frozen gas that looks like ice but burns like a candle as a possible future source of energy.

U.S. Department of Energy researchers and industry partners are analyzing data from trials on Alaska's North Slope that tested a method of extracting methane from methane hydrate. That's a lattice of ice that traps gas molecules but does not bind them chemically.

An increase in temperature or a drop in pressure releases the methane, which is the main ingredient in natural gas.

The Alaska research tested a technique developed by ConocoPhillips and the University of Bergen in Norway - injecting carbon dioxide into hydrate. In the lab, CO2 molecules swapped places with methane molecules, freeing methane to be harvested but preserving the ice.
