Thermodynamic, economic, and environmental performance comparison of typical geothermal power generation systems driven by hot dry rock

open access: yesEnergy Reports, 2022
Hot dry rock has attracted broad attention due to its relatively high temperature and abundant resources. To match the power generation system suitable for low dryness hot dry rock geothermal fluid, this paper constructed four power generation systems ...

Geomechanical performance of a novel L-shaped wellbore design for hot dry rock geothermal reservoirs: insights from fully coupled thermo-hydro-mechanical modeling [PDF]

open access: yesScientific Reports
Enhanced Geothermal Systems (EGSs), developed to extract heat from hot dry rock (HDR) formations, are promising renewable heat resources; however, their long-term performance is governed by coupled thermo-hydro-mechanical (THM) processes.

Research on a novel type of hot dry rock power generation system coupled with Kalina and ORC

open access: yesEnergy Reports, 2022
To improve the utilization of hot dry rock resources, a novel type of hot dry rock power generation system is proposed in this paper. In this system, the Kalina system is coupled with the organic Rankine cycle (ORC) system. Combined with the operating parameters of the geothermal power generation project in Husavik, Iceland, the parameters of the ...

Temperature-dependent scale precipitation in the Hijiori Hot Dry Rock system, Japan

open access: yesGeothermics, 2008
Mineral scales were formed in wells and surface installations during a 2-year circulation test performed at the Hijiori Hot Dry Rock (HDR) site, Yamagata, Japan. Anhydrite deposited in the deeper parts of the production wells, while silica and calcium carbonate precipitated at the surface, downstream of the wellhead, in amounts that depended on the ...

Lithospheric thermo-rheological structure of the Huangshadong geothermal field in Huizhou of Guangdong and its heat-sources implications

open access: yesShuiwen dizhi gongcheng dizhi, 2023
The thermo-rheological structure of the lithosphere is an effective method to reveal the thermal state within the lithosphere. Studies of the thermo-rheological structure of the lithosphere in geothermal anomaly areas can effectively constrain the ...

Mathematical model of a Hot Dry Rock system [PDF]

open access: yesGeophysical Journal International, 1991
SUMMARY We derive a mathematical model which can be used to determine the evolution of the temperature in a Hot Dry Rock system. The essential feature of this approach is given by the fact that the solution is available by analytical methods. Therefore, long-term predictions of the evolution of the temperature as well as a detailed study concerning the
