Although the traditional use of solid fuels such as coal for electric power generation in the U.S. has declined, other uses for solid fuels and their byproducts are rapidly evolving. Internationally, construction of new generation facilities to provide electricity to previously underserved areas has kept worldwide coal demand steady. The Evolving Utilization of Solid Energy Fuels (EUSEF) project...

Carbon dioxide (CO2) can react with silicate rocks that are rich in magnesium, calcium, and iron to precipitate carbonate minerals. This process is typically referred to as carbon mineralization, which represents a potential mitigation option for rising CO2 concentrations in the atmosphere. The U.S. has pledged to reduce net greenhouse gas pollution to 50-52 percent of 2005 levels, which will...

The primary objective of this project is to provide information on the volume, quality, impacts, and possible uses of water produced during generation and development of energy resources (particularly hydrocarbons) as well as related fluids injected into reservoirs for energy development and associated waste disposal. The purpose of this work is to address scientific and societal questions...

The Geoinformatics Technology Optimization (GTO) project develops applications, databases, and other related technologies to assist Geology, Energy & Minerals Science Center (GEMSC) scientists in their research activities and distribution of their data to the public.

The United States Large-Scale Solar Photovoltaic Database (USPVDB) provides the locations and array boundaries of U.S. ground-mounted photovoltaic (PV) facilities with capacity of 1 megawatt or more. It includes corresponding PV facility information, including panel type, site type, and initial year of operation. The creation of this database was jointly funded by the U.S. Department of Energy...

The Gulf Coast Geologic Energy Assessments and Research (GEAR) project assesses and characterizes undiscovered, technically recoverable domestic petroleum resources. It focuses on the onshore and State waters portion of the Gulf Coast basin. The primary goal of this project is to meet the needs of Congress and other stakeholders for timely and robust assessments of petroleum resources in the Gulf...

A petrographic thermal index is typically an organic matter indicator in sedimentary rocks that allows for estimations of burial temperature. Petrographic thermal indices include the commonly used proxy vitrinite reflectance as well as other approaches such as solid bitumen reflectance, fluorescence, micro-Raman, and micro-Fourier transform infrared (FTIR) spectroscopies. Measurements from these...

The National Coal Resources Data System (NCRDS) began as a cooperative venture between the USGS and State geological agencies in 1975 and focused on the stratigraphy and chemistry of coal.

The National Coal Resources Data System (NCRDS) State Cooperatives project supports a publicly available database of coal knowledge that encompasses the entire United States. State-level partnering for coal resource assessment and fundamental research of energy-bearing strata improves the ability of Federal, State and local planners to make optimum policy decisions in the areas of energy...

The AGGER project’s purpose is to advance the understanding of geologic energy sources, generation, composition, movement, and production potential, including resource recovery from energy wastes.

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...

Carbon Dioxide (CO2) is utilized by industry to enhance oil recovery. Subsurface CO2 storage could significantly impact reduction of CO2 emissions to the atmosphere, but the economics and potential risks associated with the practice must be understood before implementing extensive programs or regulations. Utilization of other energy-related gases such as helium (He), if separated and concentrated...
