Millions of railcars leave the Powder River Basin every year, carrying hundreds of millions of tons of coal. Those are big numbers, but the coal we mine is just a small fraction of what’s underground. Most of the basin’s coal reserves are buried too deep for conventional mining.
An Australian company called Linc Energy wants to use a technology known as underground coal gasification to tap those deep coal reserves and turn them into fuel. But as Wyoming Public Radio’s Stephanie Joyce reports, that might come at the peril of another valuable resource: water.
