A novel application of the geothermal asphalt pavement: A feasible E-fuel source

open access: yesTransportation Engineering, 2023
In this study, a novel application of geothermal technology was proposed and evaluated as a potential sustainable clean energy source. The proposed system incorporates thermoelectric generators (TEG) to transform the extracted heat from the pavement into

The size and polydispersity of silica nanoparticles under simulated hot spring conditions [PDF]

open access: yes, 2008
The nucleation and growth of silica nanoparticles in supersaturated geothermal waters was simulated using a flow-through geothermal simulator system. The effect of silica concentration ([SiO2]), ionic strength (IS), temperature (T) and organic additives ...

Deep Regional Fluid Pathways in an Extensional Setting: The Role of Transfer Zones in the Hot and Cold Degassing Areas of the Larderello Geothermal System (Northern Apennines, Italy)

open access: yesGeochemistry, Geophysics, Geosystems, 2023
High‐temperature geothermal areas are often characterized by widespread surficial manifestations, whose location is strictly controlled by sets of faults of regional relevance.

Influence of local thermal non-equilibrium on enhanced geothermal system

open access: yesShenzhen Daxue xuebao. Ligong ban, 2022
Effective development of hot dry rock depends on complex fracture network formed by the enhanced geothermal system. Different scales of mass and heat transfer environment are formed between tight matrix and different fractures, which leads to the ...

Overcoming challenges in the classification of deep geothermal potential [PDF]

open access: yes, 2015
The geothermal community lacks a universal definition of deep geothermal systems. A minimum depth of 400 m is often assumed, with a further sub-classification into middle-deep geothermal systems for reservoirs found between 400 and 1000 m.

Sustainable operation of geothermal power plants: why economics matters

open access: yesGeothermal Energy, 2021
This paper, based on a novel hybrid techno-economic model for geothermal power plants with endogenized plant lifetime, investigates the economic feasibility of a sustainable exploitation of geothermal resources for electricity generation.

Data Processing Protocol for Regression of Geothermal Times Series with Uneven Intervals [PDF]

open access: yes, 2019
Regression of data generated in simulations or experiments has important implications in sensitivity studies, uncertainty analysis, and prediction accuracy. Depending on the nature of the physical model, data points may not be evenly distributed.

Frequency‐Dependent Moment Tensors of Induced Microearthquakes [PDF]

open access: yes, 2019
Analysis of 984 induced microearthquakes from The Geysers geothermal reservoir in California reveals that the retrieved moment tensors depend on the frequency band of the inverted waveforms. The observed dependence is more significant for the percentages
