Champions of coal say the superabundant fossil fuel can be made environmentally friendlier by refining it with chemicals – a “clean coal” technology backed by a billion dollars in U.S. government tax subsidies annually.

But refined coal has a dirty secret. It regularly fails to deliver on its environmental promises, as electric giant Duke Energy Corp found.
