This project evaluates appropriate cycle and equipment selections for the utilization of supercritical or high superheat geothermal resources. Two preliminary approaches have been presented in the literature: direct admission to the turbine, and a binary cycle. Both of these approaches have serious challenges due to material limitations. The goal of the work was to develop model-driven comparisons and map operating regions to identify the relative merits of different cycle configurations, and quantify the potential improvements in economy or barriers to be overcome above those present for a more conventional plant.
