Abstract

Second law analysis plays an important role in the economics of geothermal energy. The second law operates mainly through the temperature of the geothermal fluid, since the sink temperature in geothermal systems, for practical purposes, is fixed by climatic conditions. The value of a geothermal fluid is largely determined by its available work, or exergy. The exergy and value of a geothermal fluid increase rapidly with temperature over the normal range of geothermal resource temperatures. Geothermal resources vary in temperature from ambient to over 300 °C. The cost of generating electricity from geothermal resources is very sensitive to the resource temperature, and to other factors in combination with temperature.
