Trace Elements in Energy Fuels
Completed
By Geology, Energy & Minerals Science Center
November 13, 2018
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.

Geochemistry of Energy Fuels Project
Since its establishment in 1879, USGS geoscientists have investigated the geochemistry of energy resources. Research conducted in the Geochemistry of Energy Fuels project continues this tradition. Goals include 1) understanding the geologic, geochemical, microbiological, and other factors that control production, quality, and composition of coal, petroleum, and nuclear fuels, and 2) predicting the...
Geochemistry of Energy Fuels Task
Geologic and geochemical processes that impact fuel quality, quantity, and availability can be best understood by utilizing a range of approaches, including, but not limited to isotopic signatures, inorganic and organic analyses, and neutron scattering techniques. Current work focuses on using neutron scattering to understand how fluids are stored and flow through tight continuous reservoirs and...
Molecular Fingerprinting of Energy Materials
The chemical composition of complex solid organic matter (OM) from sedimentary reservoirs is a key parameter in the generation of hydrocarbon fuels. Vibrational spectroscopies such as Fourier transform infrared (FTIR) and Raman have been widely applied to understand the molecular make-up of these hydrocarbon precursors, as well as provide links to their thermal histories via correlation to proven...
Byproducts of Energy Fuels
This task provides detailed information on the use and resource potential of energy by-products, as well as controls on the potential mobility of contaminants resulting from transport, storage, and disposal of these byproducts. Specific topics investigated include 1) transport and fate of organic and inorganic contaminants during storage and disposal of waste coal and coal combustion byproducts...
NORM Byproducts of Energy Resources
Naturally Occurring Radioactive Material (NORM) is found in waste produced during the extraction of uranium, phosphate, rare earth elements (REE), coal, oil and gas resources. The focus of this effort is to understand the potential for byproduct recovery of U-235 and Th-232, the fissionable isotopes used to generate nuclear energy from wastes produced during energy resource development. The NORM...
Microbial Methanogenesis and Strategies for Enhancements
Microbial (biogenic) natural gas is present in shale, coal and petroleum reservoirs and is estimated to account for 20% of the world’s natural gas resources. We provide hydrological, geochemical and microbial information related to the production of biogenic natural gas and new methods to monitor and enhance the production of this energy resource. Generating microbial methane at a faster rate from...
Maps of Energy Occurrence
The primary objective of this task is to produce digital maps coal-bearing areas and related energy sources and materials of the U.S., and internationally. The approach for creating GIS representations of energy sources of the U.S. and the world is to use existing geologic GIS data where possible, supplemented by data on location, rank and age from published maps and reports. Each GIS database...
Controls on Unconventional Oil and Gas Production
This scoping task incorporates insights from new approaches to production of unconventional resources and currently focuses on conducting a pilot assessment of biogenic natural gas resources in the Permian Basin. For the pilot assessment to occur, we are developing a database that will host geochemical parameters known to be suggestive of microbial methanogenesis mined to the reservoir level for...
