ABSTRACT
To be viable, use of a geothermal resource for power generation depends on satisfying the four following conditions:
1. The existence of sufficient heat. Usually, for the current state-of-the-art power generation equipment, the minimum temperature is about 95°C. However, the actual minimum temperature at any particular site depends upon the temperature at the back-end of the power generation cycle, that is, the ΔT. For most locations, the minimum temperature will be tens of degrees greater than the minimum that is currently possible.
