|Project Title||Dixie Valley Bottoming Binary Project|
|Project Type / Topic 1||Recovery Act: Geothermal Technologies Program|
|Project Type / Topic 2||Geothermal Energy Production from Low Temperature Resources, Coproduced Fluids from Oil and Gas Wells, and Geopressured Resources|
|Project Type / Topic 3||Low Temperature Resources|
|Project Description||The proposed two-year project supports the DOE GTP’s goal of promoting the development and commercial application of energy production from low-temperature geothermal fluids, i.e., between 150°F and 300°F. The proposed activities will demonstrate the technical and economic feasibility of electricity generation from nonconventional geothermal resources of 223°F using the first commercial use of a supercritical cycle at a geothermal power plant inlet temperature of less than 300°F.|
|Objectives|| -Proving the technical and economic feasibility of utilizing the available unused heat to generate additional electric power from a binary power plant from low-temperature brine at the Dixie Valley Geothermal Power Plant.
-Providing non-proprietary data to the NGDS and DOE GTP for two years. -Economic and environmental benefits, specifically job creation, income generation, increased tax and royalty payments, and decreased greenhouse gas emissions.
|Awardees (Company / Institution)||Terra-Gen Dixie Valley, LLC|
|Funding Opportunity Announcement||DE-FOA-0000109|
|DOE Funding Level (total award amount)||$2,000,000.00|
|Awardee Cost Share||$12,148,900.00|
|Total Project Cost||$14,148,900.00|
|Principal Investigator(s)||Gregory J. Odegard|
|Targets / Milestones|| -Perform a study to determine the technical and economic feasibility of a power generation expansion at the existing Dixie Valley Geothermal Power Plant utilizing binary technology which derives its heat source from the existing low pressure, low temperature (223°F) brine, which is currently injected into the geothermal reservoir.
-Utilize the first commercial use of a supercritical cycle at a geothermal power plant inlet temperature of less than 300°F. -Obtain the necessary permits related to the expansion. -Engineer, procure, construct, test, and commission a 4.2-megawatt electric (MWe) binary plant. -Operate and maintain the new binary plant, providing nonproprietary data to the National Geothermal Data System (NGDS) and the Department of Energy Geothermal Technologies Program (DOE GTP) for a minimum of two years.
