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).

Assessing the prospective resource base for enhanced geothermal systems in Europe

, 2014
In this study the resource base for EGS (enhanced geothermal systems) in Europe was quantified and economically constrained, applying a discounted cash-flow model to different techno-economic scenarios for future EGS in 2020, 2030, and 2050.

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.
