Ice-liked gas hydrate trapped within rock deep below the Earth's surface may hold promise for new energy sources. The ice-like substance called gas hydrate (methane gas) is trapped within rock three-quarters of a mile below. Alaska and Canada's frozen tundra, and in offshore locations scattered around America's coastline. In early 2002, PNNL researcher will obtain frozen core samples from the MacKenzie Delta in Canada that contains methane gas. These 'rock Gas' samples from the Mallik Research Well may unlock future U.S. energy independence if a safe and economic harvesting process can be perfected. Pacific Northwest National Laboratory researchers have joined with leading scientists worldwide in a collaborative effort to pursue a massive energy reserve that, by itself could keep America powered into the next century.
