New Coal-Oil Technique - A "Gold Mine" or Bust for TN?

June 13, 2007

Knoxville, TN - In the search of oil production alternatives, some in Tennessee see liquid coal as another way to cash in on the state's Appalachian coal reserves. However, a new report from the Natural Resources Defense Council points out at least one big downside to liquid coal: the process produces twice as much greenhouse gas pollution as traditional oil drilling.

Study author Deron Lovaas has researched the liquid coal method, as well as oil shale and tar sands production, and is anything but optimistic about the pollution they would generate.

"Things get much worse with all three of these alternatives, and liquid coal is the worst of the bunch. You get about twice the global warming pollution from liquid coal as you get from conventional gasoline."

Oil companies are looking for price guarantees and tax breaks to develop alternative oil, touting it as a way to reduce America's dependence on foreign oil. Lovaas argues that production pollution is just one reason for concern, and that there's more to be done to control car and truck tailpipe pollution.

"Boost efficiency, and that means cars with higher fuel economy; and look at low-polluting alternatives such as ethanol and electricity."
