Trapping Carbon, Freeing Coal: BLOG: SciAm Observations
The idea is to burn the coal but capture the carbon that the burning produces and pump it back underground.
It sounds simple. But millions of dollars have been spent–with the promise of billions more–in the thus far vain pursuit of a technology that can capture a diffuse gas (carbon dioxide), concentrate it and render it suitable for transport. Now the R.E. Burger Plant in Shadyside, Ohio, stands on the threshold of becoming the first coal-fired power plant to test both the capture and storage of the leading greenhouse gas.
