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).

Permeability Evolution and Gouge Formation During Fracture Shearing

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Hydro‐mechanical processes are crucial in shear‐controlled geoscientific applications such as enhanced geothermal systems and often result in stress‐dependent permeability changes. The present study aims to investigate shear‐induced permeability evolution of a natural sandstone fracture using a novel modeling approach.

Review of artificial intelligence applications in geothermal energy extraction from hot dry rock

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 651-672, December 2025.
This paper systematically summarized the applications of artificial intelligence (AI) in hot dry rock (HDR) geothermal exploitation and discussed the limitations and opportunities. A novel intelligent HDR exploitation system was proposed to promote the development of HDR toward more efficiency, economy, and intelligence.
