In Blow to ‘Clean Coal,’ Flawed Plant Will Burn Gas Instead

The Kemper County plant, built to take advantage of a strip coal mine next door, was three years behind schedule and, at a cost of about $7.5 billion, $4 billion over its projected budget. Equipment meant to turn the coal into gas and remove at least two-thirds of the carbon dioxide from it to keep it out of the atmosphere never worked as designed.

Last week, the Mississippi Public Service Commission issued an ultimatum about the troubled project, setting a deadline of July 6 to begin negotiations on its future and recommending that it run on natural gas....

The lignite coal that is mined adjacent to the Kemper County plant emits more climate-warming carbon dioxide per unit of heat than other coal, and far more than natural gas. Southern had intended the plant to demonstrate how even the dirtiest coal could be cleaned up. But in their statement last week, the state regulators referred to it as “unproven technology” that put shareholders and customers at financial risk.
