The Vice President of NRG energy gave a press conference at the Petra Nova plant in Texas to mark six months of operations.
The project has captured more than 700,000 tons of carbon dioxide since it began working.
Petra Nova is the largest retrofit of a coal fired power plant and will capture 1.6 million tons of carbon dioxide per year.
It captures roughly 5,200 tons of carbon dioxide a day and 94% of the carbon dioxide from the flue gas.
NRG’s vice president, David Greeson, said that the project is progressing “so far, so good”.
The project has not been 100% operational because it is in its initial period. “Probably by now, if we’d been running continuously, we’d be over a million tons captured,” Greeson said.
The project is also using the carbon dioxide to stimulate oil production in the nearby West Ranch oil field. Prior to the start of Petra Nova’s operations the field produced less than 300 barrels per day but now according to Greeson the field produces over 4000 barrels per day. It is hoped that the field’s production will rise to 15,000 barrels per day.
This week NRG energy’s stocks reached a year high of $24.12.
The US energy secretary Rick Perry has praised Petra Nova, saying: “The Petra Nova project will certainly benefit Texas, it also demonstrates that clean coal technologies can have a meaningful and positive impact on the nation’s energy security and economic growth.”
