From Environmental Science and Technology Online (Mercury control costs drop):
The cost of controlling mercury from coal-fired power plants can be up to 50% less than the 1999 baseline estimates, according to an economic analysis from the U.S. Department of Energy (DOE). The new report, published today on ES&T’s Research ASAP website (DOI: 10.1021/es0617340), focuses on a well-known technology, activated carbon injection (ACI), and has sparked interest from electric utilities and environmental advocates who sparred over EPA’s Clean Air Mercury Rule (CAMR) when it was released in 2005.
