Location: Kemper County, Mississippi, United States of America

Proponent: Mississippi Power (Southern Company)

Technical aspects

• 582 MW net coal-based integrated gasification combined cycle (IGCC) power plant.
• 3.5 million tonnes per annum of carbon dioxide (CO₂) is expected to be captured.
• The project would utilise two transport integrated gasifier trains, each with its own coal feed and ash handling systems.
• CO₂ is transported via pipeline for onshore enhanced oil recovery.

Key Deliverables

• Financial investment decision taken in May 2010.
• Construction commenced June 2010.
• Operation expected in 2014.
• This project was one of two selected in the second round of the US Department of Energy's Clean Coal Power Initiative. It received US$270 million in funding to demonstrate advanced power generation systems using IGCC technology.

This project highlights a technology - the transport gasifier - that has been used successfully for over 50 years in the petroleum refining industry. The transport gasifier is air-blown and has a fuel-flexible design projected to have higher efficiency and lower capital and operating costs than the currently available oxygen-blown entrained-flow gasifiers. The demonstration plant will generate electricity using Mississippi lignite.
