Kinetic characterisation of sandstone exposed to high temperature-water cooling cycle treatments under the impact loading: from the perspective of geohazard

Geohazard Mechanics
Enhanced Geothermal Systems (EGS) improve geothermal energy extraction but can rapidly cool high-temperature rocks, leading to internal fractures that weaken mechanical properties and pose risks such as well collapses and seismic events.

Research on power generation system with Organic Rankine Cycle for hot dry rock resources in Xinghua area

Journal of Physics: Conference Series
Abstract Although China is rich in hot dry rock (HDR) resources, its application for the power generation process started late, and there is limited successful experience currently. To explore the power generation scheme for HDR resources in the Xinghua area, a power generation system with an organic Rankine cycle (ORC) with a re-heater ...
