COAL-TO-LIQUID fuel is being touted in the Senate energy debate as a key to overcoming America's dependence on foreign fuel. The argument is understandable, considering that the United States sits atop the largest coal reserves in the world, by one estimate a 200- to 450-year supply. But unanswered questions and environmental concerns raise the prospect that the price for this brand of energy independence may be too high.
To turn coal into liquid fuel it must be fired up to 1,000 degrees and mixed with water. Then the gas that's created is transformed into fuel that can be used in cars and jets. Unfortunately, creating CTL, as it is known, is a very intensive process requiring coal, water and cash. To wean the United States off of just 1 million barrels of the 21 million barrels of crude oil consumed daily, an estimated 120 million tons of coal would need to be mined each year. The process requires vast amounts of water, particularly a concern in the parched West. And the price of a plant is estimated at $4 billion.
