Clean Coal Power Initiative, US
The PurGen One Project, being developed by SCS Energy LLC, proposed a 750MW IGCC power plant plus a manufacturing facility producing hydrogen commodities at the site of a former chemical plant in Linden, New Jersey. The $5.2 billion, privately developed project planned to capture and transport 10 million tonnes of CO2 a year, and claimed access to geologic storage for around 1 trillion tonnes of CO2.
The project was to use integrated gasification combined cycle technology, with coal - to be delivered by rail or barge - being converted to a synthetic gas. After removal of CO2 and other gases, the remaining gas would have been used to produce hydrogen commodities, such as urea, which is used for pollution control in cars, industrial plants and for fertilizer, and to power a combined cycle power plant.
The project, which was subject to intense local opposition, had expected extensive regulatory scrutiny by federal, state, and local agencies.
No longer under development.
The offshore repository selected for PurGen One, seventy miles off New Jersey's coast, has been extensively characterized in the course of offshore oil and gas exploration and is nearly identical to the geology of the Sleipner field in the North Sea. A major difference is that the formation where PurGen One's carbon dioxide would have been stored is deeper and covered by a thicker and more dependable cap rock than the formation successfully used at Sleipner. Captured CO2 from the plant would have been stored in a geologic repository 8000 feet below the ocean floor and more than seventy miles from shore.
