How can Ammonia make coal plants cleaner?



  1. 0 Votes

    A pilot project in Wisconsin has reduced the amount of CO2 emitted from a coal power plant using a patented chilled ammonia process. Considered a carbon-capture technology, this process has the potential to decrease carbon dioxide emissions from a coal plant by 90% (based on test in the U.S.) through use of chilled ammonia. When CO2 comes in contact with the chilled ammonia, it is absorbed and pumped into a regeneration system, where pure CO2 is produced. In tests, about 90% of this pure CO2 was able to be captured and stored underground. Through this process, coal plants are made cleaner through the reduction of CO2 emissions.
