|Project Title||Baseline System Costs for 50.0 MW Enhanced Geothermal System -- A Function of: Working Fluid, Technology, and Location|
|Project Type / Topic 1||Recovery Act: Enhanced Geothermal Systems Component Research and Development/Analysis|
|Project Type / Topic 2||Geothermal Analysis|
|Project Description|| This effort will support the expansion of Enhanced Geothermal Systems (EGS), supporting DOE Strategic Themes of “energy security” and sub goal of “energy diversity”; reducing the Nation’s dependence on foreign oil while improving our environment. A 50 MW has been chosen as a design point, so that the project may also assess how different machinery approaches will change the costing – it is a mid point in size where multiple solutions exist that will allow the team to effectively explore the options in the design space and understand the cost.
This model and the variation in the aforementioned conditions will help answer key questions regarding the economic viability of EGS, and to what extent can the vision of EGS be achieved anywhere.
|Objectives||Develop a baseline cost model, and then exercise that model to assess variations in working fluid, top side equipment and construction / drilling technology, and location characteristics.|

|Total Project Cost||$1,554,530.00|
|Principal Investigator(s)||Bruce F. Malinowski|
|Targets / Milestones|| - Develop a baseline cost model of a 50.0 MW EGS, including all aspects of the project, from finding the resource through to operation, for a particularly challenging scenario: the deep granitic rock of the Pioneer Valley in Western Massachusetts.
|Location of Project||Milford, CT|
|Impacts||The project will develop a baseline cost model of a 50.0 MW Enhanced Geothermal System, including all aspects of the project, from finding the resource through to operation, for the deep granitic rock of the Pioneer Valley in Western Massachusetts. The project will develop an understanding of how that cost model changes with the change from H2O-EGS to CO2-EGS, with respect to key technologies, specifically: conventional vs. spallation drilling and CO2-EGS hybrid power system gas generation and processing approaches, and with respect to location, specifically: temperature profile vs. depth; geology, geo chemistry (rock type, porosity, etc); and local electric rate (as it applies to the effective cost of CO2, and EGS ROI overall). According to the application, there will be 10 jobs created and/or retained by the project.|
