Multidisciplinary approach for the sustainable utilization of medium-low temperature geothermal resources

, 2013
A growing interest in the applications of the medium-low temperature geothermal resources can be observed, but often a reference frame in this field does not exist. Different backgrounds are involved in the design and optimization of geothermal projects:

Analysis Of Geothermal Energy As An Alternative Source For Electricity In Colombia [PDF]

, 2017
Geothermal energy is the energy that is stored inside the earth and which may be used by man either directly (with no transformation) or to generate electricity by means of a geothermal power plant.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Geothermal exploration using the magnetotelluric method

, 2016
One of the requirements to realize electricity production from geothermal energy in the Netherlands is the exploration of the deep subsurface. Currently, detailed geological information below 5 kilometer is sparse.

Pulse testing in Geothermal Energy: Demonstration of a new monitoring tool. [PDF]

, 2022
Harmonic pulse testing has been employed to identify the thermal front in a geothermal system and in a heat storage system. For the geothermal system we could identify the hydraulic reservoir properties around the well.

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

Deep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Calculation of gross electrical power from the production wells in Lahendong geothermal field in North Sulawesi, Indonesia

, 2010
Geothermal energy in the Province of North Sulawesi in Indonesia has potential to produce 865 MW of electricity. One of the geothermal prospects in North Sulawesi that has been developed to generate electricity is Lahendong geothermal field.

Thermal‐induced fracture evolution and acoustic signature of Beishan granite: Insights into tensile strength of barrier system for high‐level radioactive waste disposal

Deep Underground Science and Engineering, EarlyView.
The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Geothermal energy

, 2013
In the search for new energy resources, scientists have discovered ways to use the Earth itself as a valuable source of power. Geothermal power plants use the Earth’s natural underground heat to provide clean, renewable energy.
