GeoVision Analysis Supporting Task Force Report: Electric Sector Potential to Penetration

Abstract

Department of Energy (DOE) reports produced after 1991 and a growing number of pre-1991 documents are available free via www.OSTI.gov.

Regional Energy Deployment System (ReEDS) Model Documentation: Version 2019

“…Though near-field EGS and additional deep EGS resources are not allowed under default assumptions because of uncertain feasibility, these geothermal resource categories can be included as additional resource in ReEDS. The geothermal supply curves are based on the analysis described by Augustine et al (2019) and are shown in Figure 11. The hydrothermal and near-field EGS resource potential is derived from the U.S. Geological Survey's 2008 geothermal resource assessment (Williams, Reed, and Mariner 2008), while the deep EGS resource potential is based on an update of the EGS potential from the Massachusetts Institute of Technology (Tester et al 2006).…”

Resource Assessment for Hydrogen Production

“…The United States produces the most geothermal electricity in the world, though geothermal energy currently accounts for only 0.4% of U.S. electricity generation (Augustine et al 2019) or approximately 20 TWh/year (EIA 2019, Table 17). The installed nameplate geothermal capacity is more than 3 GW (Augustine et al 2019), which can provide 2.5 GW of net summer capacity to the grid (EIA 2019g).…”

“…The technical potential of geothermal resources is based on research for the DOE Geothermal Vision (GeoVision) study and is detailed in the GeoVision Analysis Supporting Task Force Report: Electric Sector Potential to Penetration (Augustine et al 2019;DOE 2019). The geothermal resource availability estimated in the "Business-as-Usual" (BAU) scenario is shown in Table 3 and used to estimate the technical potential of geothermal power generation and hydrogen production potential.…”

GeoVision Analysis Supporting Task Force Report: Thermal Applications-Quantifying Technical, Economic, and Market Potential of Geothermal District Heating Systems in the United States

“…This assumption was based on consensus among the GeoVision Visionary Team in addition to current research efforts, such as those taking place at the DOE Geothermal Technologies Office's Frontier Observatory for Research in Geothermal Energy (FORGE) site (DOE 2018). For further discussion, see Augustine, Ho, and Blair (2019). An overview of the dGeo results is presented in this section, with more detailed descriptions of the technical (Section 5.2), economic (Section 5.3), and market potential (Section 5.4) provided in subsequent sections.…”
