| Abstract |
A number of concepts have been proposed for converting geothermal energy to electricity. The subject study was made to analyze these concepts, and compare them with conventional systems and with each other. This study was done by The Ben Holt Co. for the Electric Power Research Institute (EPRI), project number RP1673-1. A comparison was made among all of the concepts studied, including the conventional binary and flashed steam cycle. None of the little known concepts showed large potential improvement over the conventional systems. Several total flow devices, particularly in hybrid applications, are concluded to be competitive with conventional schemes. The system which showed the best potential cost and efficient is the Sperry gravity-head system. |
