Power Lunch Lecture - The 2014 Renewable Energy Date Book - Trends and Key Statisitics in Renewable Energy

Phillip Beiter, Analyst at NREL's Strategic Energy Analysis Center

Date: February 17, 2016, 12:00-1:00pm

Location: NREL Education Center, 15013 Denver West Parkway, Golden CO 80401

Summary:

The Renewable Energy Data Book offers facts and figures on energy and electricity use, renewable electricity in the United States, global renewable energy development, wind power, solar power, geothermal power, biopower, hydropower, marine and hydrokinetic power, hydrogen, renewable fuels, and clean energy investment. The newly released book illustrates United States and global energy statistics, including renewable electricity generation, renewable energy development, clean energy investments, and technology-specific data and trends. During this Power Lunch Lecture Philipp will provide an overview of the key statistics and trends represented in the 2014 Renewable Energy Data Book.

Lecture: Geochemical and Microbial Tracers of Natural Gas Formation and Transport in the Environment

Van Tuyl Lecture by Dr. Jennifer McIntosh - University of Arizona, Associate Professor, Hydrology and Water Resources

Date: February 25, 2016, 4:00 PM

Location: Colorado School of Mines, Berthoud Hall, BE 241

Summary:

Understanding the mechanisms of natural gas formation and transport in the environment is particularly timely and important given recent concern about fugitive gas emissions (e.g. related to hydraulic fracturing and shale gas production; underground gas storage facilities), and the need to transition to lower carbon emitting energy resources and store anthropogenic CO2 to mitigate climate change.  Approximately 20% of all natural gas was generated by microbes that degrade complex organic matter (e.g. oil, shale, coal) in the subsurface and produce methane.  Microbial communities may be stimulated in-situ to generate “new” methane resources, increasing the lifetime of natural gas wells and potentially converting oil to lower carbon emitting methane.  These microbial communities may also be present in near surface environments leading to natural accumulations of methane in shallow aquifers.  Distinguishing this “background” methane from fugitive gases released during natural gas drilling or storage activities, for example, is critical to address any contamination issues.  This talk presents recent hydrogeochemical and microbial results of field-based studies in the Powder River and Appalachian basins to: (1) investigate controls on the origin and distribution of natural gas (and associated water quality) in shallow aquifers in a shale-gas bearing region prior to any commercial shale gas production; and (2) determine the mechanisms of microbial coalbed methane generation and potential methods for stimulation.
