AEP Begins Sequestration of Carbon Dioxide at Mountaineer Plant

Carbon sequestration took another step forward as American Electric Power began a pilot program for storing carbon dioxide underground. The CO2, generated by AEP's Mountaineer plant, is a small part of that generated by the plant, but it's a start toward understanding how CO2 reacts to being stored underground. Here's a story from the Gazette about the project.
Here's some more information about carbon sequestration in its broadest form, from Wikipedia.
