Investigation of geothermal energy technologies and gas turbine hybrid systems
This paper presents a preliminary study of the technical and economic feasibilities of integrating gas turbine systems into geothermal technologies. Levelized cost analysis employing revenue requirement approach was used to measure the economic feasibility of the geothermal and gas turbine hybrids at different geothermal sites. Twelve geothermal resource areas were included in this study; Brawley, CA, Coso Hot Springs, CA, Dixie Valley, NV, East Mesa, CA, Glass Mountain, CA, Heber, CA, Mono-Long Valley, CA, Salton Sea, CA, Stillwater, NV, Surprise Valley, CA, Vale, OR, and Wabuska, NV. The geothermal power generation technologies included in this study were air-cooled subcritical binary, condensate-cooled dual flash, and gas turbine hybrids of these two technologies. Geothermal/gas turbine concepts can be cost-effective at many geothermal resource areas. This study indicated that integrating gas turbine systems using GE LM2500 with binary cycles is potentially more cost effective than stand alone binary power plants in low temperature resource areas such as East Mesa, CA, Heber, CA, Stillwater, NV, Vale, OR and Wabuska, NV. In addition, this study showed that dual flash/gas turbine hybrid power plants maybe considered for higher temperature resources with high O&M costs.
