Trace Elements in Energy Fuels

Science Center Objects

In this task we conduct new interpretive studies of the concentration and distribution of trace metals and mercury in coal and other energy materials. Complementary studies of coal combustion products are conducted under Task 8. Together with use of existing USGS databases, we examine the potential for reducing emissions of potentially toxic substances by coal preparation, and by optimizing coal quality parameters such as halogens that enhance mercury capture. We conduct detailed studies of the distribution of mercury and other potential contaminants in U.S. coal resources to evaluate and predict the distribution of these constituents, to determine their potential for reduction, and help support assessment work.
