Back in June the US Department of Energy announced that it would be investing $90 million into research advancing Enhanced Geothermal Systems— a geothermal power technology which could expand the already considerable geothermal power potential of the United States. Well the DOE has announced the lucky winners. There are 21 awardees who will be receiving a total of $43.1 million over the next four years; with the cost-sharing provisions of the Funding Opportunity Announcement, the total awards amount to $78 million. Presumably there will be another announcement for the rest of the previously announced funding. Here’s who’s receiving some federal cash and what they’re working on:What’s an Enhanced Geothermal System Anyway?
Before we do that though, and so everyone’s on the same page, this is what Enhanced Geothermal Systems are about (the video is from Google, who have recently backed the technology):

That out of the way, here’s the DOE funding list:

The ultimate goal is to develop an industrial tool to obtain detailed seismic structure of geothermal areas without the need for major active-source seismic surveys (up to $561,729).

GE Global Research with Auburn University and GE Energy (Niskayuna, N.Y.): to develop a platform of electronics technologies that can operate at 300 °C and 10 km depth enabling the measurement of temperature, flow, pressure and seismicity in an EGS reservoir (up to $1,599,934).

Hattenburg, Dilley, and Linnell, LLC with University of Utah/Energy and Geoscience Institute (EGI) (Anchorage, Alaska): to identify open fracture systems by their Fluid Inclusion Stratigraphy (FIS) chemical signature; differences based on the mineral assemblages and geology of the system; and chemical precursors in the wall rock above open, large fractures (up to $313,858).

Hi-Q Geophysical Inc., Ormat Technologies, Inc. and Stephen Muir with DOE’s Lawrence Berkeley National Laboratory (Ponca City, Okla.): to develop surface and borehole seismic methodologies using both compression and shear waves for characterizing fractures in EGS. Both VSP and surface multi-component acquisition geometries will be evaluated (up to $817,757).

Massachusetts Institute of Technology, Chevron and DOE’s Los Alamos National Laboratory (Cambridge, Mass.): to combine detailed high-resolution analysis of microseismicity accompanying the stimulation of an EGS reservoir with a state-of-the-art geomechanical model of the reservoir to investigate the relationship between the seismicity and flow characteristics  (up to $508,633).
