The U.S. Department of Energy's National Energy Technology Laboratory (DOE/NETL), under the Office of Fossil Energy's Innovations for Existing Plants (IEP) Program, has managed full-scale field tests of mercury (Hg) control technologies at nearly 50 U.S. coal-fired power plants over the past seven years. The high performance observed during many of these field tests, coupled with the reliability of Hg control system operations, has given coal-fired power plant operators the confidence to begin deploying technology. As of October 2007, over 10% of total U.S. coal-fired power generation capacity had placed orders for full-scale activated carbon injection (ACI) systems, a signature technology of the IEP Program. The ACI systems have the potential to remove more than 90% of the Hg in most applications, at a cost that can dip below $10,000 per pound of Hg removed.
