Geothermal Power Generation and CO2 Capture Co-Production

Abstract

Key Accomplishments and Milestones Cont. Started site-specific analysis of geothermal data at Hot Pot Acquired project files from GTO on Hot Pot Phase 1 (Oski Energy) Synthesis of seismic, gravimetric and shallow gradient wells data Examination of local geology including areas near the North Valmy plant site that were not considered in the Oski Hot Pot project Investigation of development rights status for the site Started site-specific analysis of North Valmy Power Station Information on plant configuration, power generation, and fuel use gathered from EIA database and plant heat rate calculated Reviewed internet information concerning future operation of the North Valmy Station and environmental targets Ambient conditions assumed to be similar to Winnemucca, NV for which National Oceanic & Atmospheric Administration data was obtained Constructed a detailed ASPEN Plus® model of a subcritical power plant’s steam cycle and matched North Valmy’s heat rate with it Drafted an itemized question list for discussion with plant operator to estimate benefit of geothermal heating of boiler feedwater
