Company/Alliance: NRG Energy and Powerspan Corporation
Location: WA Parish plant, Houston, Texas, USA
Feedstock: Coal
Size: 125 MW. Up to 1 Mt/Yr CO2 captured.
Capture Technology: Powerspan's Post-combustion ammonia-based electrocatalytic oxidation technology (ECO2)
CO2 Fate: EOR
Timing: Operational by 2012
Motivation/Economics: Test Powerspan's new CO2 capture method ECO2 at power-plant scale. EOR will provide revenue. The technique also generates ammonia which can be sold. The ECO2 capture method is more energy efficient than conventional CO2 scrubbing of flue gases and as such it is projected to have a lower CO2 capture cost.
Comments: The NRG energy's WA Parish plant is one of the US's worst CO2 pollutants. This project will decrease the emission of pollutants of CO2 by 90% as well as SOx, NOx, mercury and particulate emissions. Powerspan's ECO2 capture technology on the pilot scale 1-5 MW range has been successful. This $150 million project will show ECO2 is capable for full scale power stations.
