DOE Selects Tampa Electric Site for Carbon Capture Project Grant

LCG, July 20, 2010--The Department of Energy (DOE) selected Tampa Electric's Big Bend Station for a carbon capture project that will receive an $8.9 million grant. This pilot plant was one of ten selected by the DOE to improve efficiencies and lower costs for carbon capture technologies employed at coal-fired power plants.

The project will demonstrate new POSTCAP technology that uses an amino acid salt as a solvent for CO2 absorption. Siemens Energy will design, install, and operate a pilot plant to capture 90 percent of the CO2 from a slipstream (1 MW equivalent) of the post-combustion exhaust gas. The flue gas will be extracted downstream of an existing Siemens Wet FGD system. A benefit of using the non-toxic, biodegradable solvent is a more environmentally friendly process.

The pilot project is scheduled to commence operations in 2013. Siemens began operations of its first pilot CO2 capture plant for coal-fired power plants at the Staudinger power plant in Germany in September 2009.
