Two recent projects to capture and store carbon emissions from large coal-fired powerplants have had very different outcomes: One was completed this spring and is undergoing testing and commissioning; the other is months behind schedule and way over budget.
The Boundary Dam project in Saskatchewan went up relatively smoothly, although there were challenges during the construction phase, says SaskPower President and CEO Robert Watson. But the Kemper County carbon capture and storage (CCS) project in Mississippi has been plagued with problems and setbacks; most recently, this spring, Southern Co., the owner, announced the plant would likely not be operational until the first quarter of 2015.
