An $8 million pilot project in Wisconsin successfully showed that carbon dioxide can be captured and kept from being released from the smokestacks of coal-fired power plants, We Energies and two partners said Thursday.
An $8 million pilot project in Wisconsin successfully showed that carbon dioxide can be captured and kept from being released from the smokestacks of coal-fired power plants, We Energies and two partners said Thursday.
The project was the first real-life demonstration of technology that uses chilled ammonia to act as a magnet to capture the greenhouse gas and purify it for possible shipment into underground geological formations instead of into the air.

The Wisconsin project, at the Pleasant Prairie Power Plant, was able to grab at least 90% of the greenhouse gas, officials said, and the French company Alstom that developed the technology is optimistic its next test will capture even more carbon dioxide.
Testing at the Milwaukee electric utility's power plant has continued since September 2008, the companies said.
The test is scheduled to be completed at the end of this month.
