High Temperature Friction and Strength of Felsite and Basalt: Implications for Supercritical EGS at Krafla, Iceland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

Power Losses in Energy Generation: Mechanisms, Mitigation Strategies, and Pathways to a Sustainable Future

Energy Technology, Volume 14, Issue 4, April 2026.
This article provides a comprehensive review of loss mechanisms in the generation stage of energy systems, covering fossil, nuclear, and renewable technologies. It examines their environmental and operational implications and shows how overlooking generation losses distorts efficiency assessments.

Repurposing of hydrocarbon wells for Enhanced Geothermal System (EGS) development [PDF]

Geothermics
The Groß Schönebeck research platform represents a case study for the reuse of the abandoned hydrocarbon well E GrSk 3/90. A detailed description of well selection criteria, subsurface conditions, and well modification procedures is presented as a workflow for the repurposing of hydrocarbon well as an injection well for an EGS development.

From Points to Planes: A Workflow for Converting Three‐Dimensional Point Cloud Data Into Discrete Fracture Network Flow and Transport Models

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract We present the Point cLoud Algorithm for NEtwork Extraction of Discrete Fracture Networks (PLANE‐DFN), a point cloud–based algorithm for automatic fracture network extraction designed to support discrete fracture network (DFN) modeling workflows. PLANE‐DFN segments three‐dimensional fracture planes from raw point cloud data using RANdom SAmple

Theoretical Maximum and Cumulative Seismic Moment Relationships Confirm that Injection Volume Controls the Occurrence Rate, But Not the Magnitude, of Induced Earthquakes

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Classical relationships between cumulative and maximum seismic moment, based on the Gutenberg‐Richter law, shows a non‐physical anomaly for low b‐values. We here derive new relationships, including a low and a high b‐value approximation.
