Comparative Analysis of Power Plant Options for Enhanced Geothermal Systems (EGS)
Enhanced geothermal systems (EGS) extract heat from underground hot dry rock (HDR) by first fracturing the HDR and then circulating a geofluid (typically water) into it and bringing the heated geofluid to a power plant to generate electricity. This study focuses on analysis, examination, and comparison of leading geothermal power plant configurations with a geofluid temperature from 200 to 800 ...
متن کاملA Selection Method for Power Generation Plants Used for Enhanced Geothermal Systems (EGS)
As a promising and advanced technology, enhanced geothermal systems (EGS) can be used to generate electricity using deep geothermal energy. In order to better utilize the EGS to produce electricity, power cycles’ selection maps are generated for people to choose the best system based on the geofluids’ temperature and dryness conditions. Optimizations on double-flash system (DF), flash-organic R...
متن کاملFundamental Investigation Of Whole-Life Power Plant Performance For Enhanced Geothermal Systems
This paper presents a fundamental investigation of the use of conventional Rankine Cycle, Trilateral Flash Cycle, and wet vapour Rankine Cycle system for the generation of power from Enhanced Geothermal Systems. The paper considers ideal Carnot, Trilateral and Quadlateral cycles, and compares the ideal cases of maximum rate of power production with maximum total electricity delivery. These resu...
متن کاملNumerical Studies of Fluid-rock Interactions in Enhanced Geothermal Systems (egs) with Co2 as Working Fluid
There is growing interest in the novel concept of operating Enhanced Geothermal Systems (EGS) with CO2 instead of water as heat transmission fluid. Initial studies have suggested that CO2 will achieve larger rates of heat extraction, and can offer geologic storage of carbon as an ancillary benefit. Fluid-rock interactions in EGS operated with CO2 are expected to be vastly different in zones wit...
