Performance of Hybrid Single Well Enhanced Geothermal System and Solar Energy for Buildings Heating

Energies, 2020
The energy reserves in hot dry rock and hydrothermal systems are abundant in China, however, the developed resources are far below the potential estimates due to immature technology of enhanced geothermal system (EGS) and scattered resources of ...

Finnish crustal-scale faults as a possible source of deep low-enthalpy geothermal resources [PDF]

, 2021
Crustal-scale faults deserve more attention as potential deep low-enthalpy geothermal energy sources in Finland. As well known, major structures may behave as favourable permeability channels for meteoric waters.

Fault Stability Assessment in Tectonically Active Geothermal Fields Through Integrated Stress Analysis

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The Tulu Moye geothermal field in the actively deforming Main Ethiopian Rift presents substantial potential for renewable energy production, where interactions between fault systems, hydrothermal fluids, and tectonic activity require careful management for sustainable development. Here we present a first‐order assessment of fault stability and

Fault Slip and Fluid Flow: Seismic Source Analysis to Assess Role of Multiple Slip Patches in Fault Permeability

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The relationship between fault reactivation, microearthquakes (MEQs), and permeability evolution during fluid injection plays a critical role in energy harvesting and waste disposal. Recent studies have demonstrated the possibility of predicting fault permeability using cumulative seismic moments of MEQs quantitatively.

In Situ Microscale Shear Failure Mechanism in Hot Dry Rock Under Thermal Cycling

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Induced shear failure is key for enhancing hot dry rock (HDR) resource exploitation, aiming to creating an extensive fracture network. Although the macroscopic shear behavior of HDR has been extensively investigated, its microscopic shear failure mechanisms remain unclear.

Techno‐Economic Assessment of Green Hydrogen Production Using Supercritical Geothermal Energy and Solid Oxide Electrolysis

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Green hydrogen uses renewable energy to power electrolysis and dissociate water into hydrogen and oxygen, making it an environmentally sustainable alternative to grey and black hydrogen, which both require fossil fuels (using natural gas and coal, respectively).
