Abstract

Geothermal power plants are one of the environmentally benign systems among other types of power generation systems. In this chapter, the exergy efficiencies and exergy destruction rates are analyzed for the binary geothermal. In addition, greenhouse gas (GHG) emissions (in ton CO2-eq/kWh) during operation as well as the sustainability index are determined under various operating conditions. For the case study presented here, it is shown that the Dora II binary geothermal power plant produces no GHG emissions during operation since no fossil fuels are burned. For the same production capacity, it helps reduce the emissions by 56 Mega Ton CO2-eq/yr compared to a coal-fired power plant and 28 Mega Ton CO2-eq/yr compared to a natural gas combined cycle power plant.
