To Bleed‐Off or Not to Bleed‐Off?

Geophysical Research Letters
Bleed‐off and shut‐in of injection have been implemented in different Enhanced Geothermal Systems (EGS) in an attempt to mitigate the induced seismicity at and after the injection stop.

Carbon negative platform chemicals from waste using enhanced geothermal systems

, 2018
Australia has ample geothermal resource, however, it is of low-grade heat and requires Enhanced Geothermal Systems (EGS). Integrating heat recovered via EGS into a lignocellulosic biorefinery opens the avenue for countless opportunities in biomass to ...

Comparative investigation of the heat extraction performance of an enhanced geothermal system using H2, CO2, and H2O as working fluids

Energy Geoscience
The optimization of working fluids in single-well coaxial geothermal systems presents a critical pathway for advancing the use of enhanced geothermal systems (EGS) in renewable energy applications. This study evaluates the thermo-hydraulic performance of
