The Geothermal Technologies Office (GTO) is interested in research that addresses the overarching theme of uncertainty quantification and reduction, specifically through the development of Geothermal Play Fairways. A play fairway analysis defines levels of uncertainty with respect to the presence and utility of geothermal system elements, and translates them into maps to high grade the geographic area over which the most favorable combinations of heat, permeability, and fluid are thought to extend. This analysis is conducted on a regional (basin) scale, with the resulting maps covering areas of up to several thousand square miles. The purpose of this Notice is to provide potential applicants advance notice that the Geothermal Technologies Office (GTO), on behalf of the DOE Office of Energy Effieicency and Renewable Energy (EERE), intends to issue a Funding Opportunity Announcement (FOA) titled, "Geothermal Play Fairway Analysis." NO APPLICATIONS WILL BE ACCEPTED THROUGH THIS NOTICE. Please do not submit questions or respond to this Notice of Intent. Prospective applicants to the FOA should begin developing partnerships, formulating ideas, and gathering data in anticipation of the issuance of the FOA. It is anticipated that this FOA will be posted to EERE Exchange in January, 2014.
