The Kemper County energy facility is an electric power plant using an integrated gasification combined cycle (IGCC) design called TRIG™ technology.
TRIG™ was developed over the last two decades at the Power Systems Development Facility (PSDF) in Wilsonville, Alabama - a research facility for the Department of Energy and Southern Company.
A unique feature of the TRIG™ technology is the high-efficiency design that sends lignite not converted to gas in the initial process back for a second round of gasification. This allows a high rate of lignite-to-gas conversion to take place at a lower temperature — and thus lower cost — than what's possible with other available gasification technologies.
TRIG™ produces gas that can be used to generate electricity while making it easier to remove emissions, such as carbon dioxide, that otherwise would end up in the atmosphere.
