Mathematical model of a Hot Dry Rock system [PDF]

Geophysical 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

Hot dry rock energy: Hot dry rock geothermal development program. Progress report. Fiscal year 1993 [PDF]

, 1995
Extended flow testing at the Fenton Hill Hot Dry Rock (HDR) test facility concluded in Fiscal Year 1993 with the completion of Phase 2 of the long-term flow test (LTFT) program. As is reported in detail in this report, the second phase of the LTFT, although only 55 days in duration, confirmed in every way the encouraging test results of the 112-day ...

Hot dry rock at Fenton Hill

Eos, Transactions American Geophysical Union, 1979
The concept is almost as simple as extracting free heat from the sun. Any geophysicist knows of the geothermal gradient and has thought at one time that eventually geothermal heat will have to be tapped as a source of energy. To quote a brochure published by the Los Alamos Scientific Laboratory (LASL), ‘Naturally heated rock in the earth's crust is one

Acord 1-26 hot, dry well, Roosevelt Hot Springs hot dry rock prospect, Utah [PDF]

, 1983
The Acord 1-26 well is a hot, dry well peripheral to the Roosevelt Hot Springs known geothermal resource area (KGRA) in southwestern Utah. The bottom-hole temperature in this 3854-m-deep well is 230/sup 0/C, and the thermal gradient is 54/sup 0/C/km. The basal 685 m, comprised of biotite monzonite and quartz schist and gneiss, is a likely hot, dry rock

Mechanical Characteristics and Permeability Characteristics of Dry-Hot Rock Mass

Journal of Environmental and Public Health, 2023
As a rock mass with shallow burial, high temperature, and large-scale development, the study of its mechanical and seepage characteristics plays an important role in the efficient development of geothermal energy. With the development of geothermal energy in China, a breakthrough has been made in the exploration of dry-hot rocks, and the realization of

Mitigating Concentration Polarization in Dry‐Processed Ultra‐Thick Cathodes Using a Low‐Viscosity Electrolyte With Soft Li+ Solvation

Advanced Functional Materials, EarlyView.
A low‐viscosity, soft‐solvating methyl ethanoate (ME)‐based electrolyte facilitates electrolyte infiltration into dense dry‐processed ultra‐thick NCM622 cathodes while reducing Li+ desolvation barriers at Li‐metal anodes. Balanced cathode‐scale ion transport and anode‐side interfacial kinetics mitigate concentration polarization and interfacial ...

Impacts of Temperature and Pressure on the Thermophysical Properties of Granites

Energy Exploration & Exploitation
The thermophysical properties of rocks are identified as basic physical parameters for the exploitation and utilization of hot dry rock (HDR) geothermal resources. Given that reservoirs in a HDR system are subjected to a certain temperature and pressure,

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
