Deep Underground Science and Engineering, EarlyView.Our study reveals that caving‐enhanced geothermal systems (C‐EGS) with adequately fractured reservoirs achieve optimal heat extraction by minimizing preferential flow paths, while conventional fracturing (F‐EGS) and pipe‐based (P‐EGS) systems suffer accelerated thermal drawdown.

An Early Numerical Prediction of the United Downs Deep Geothermal Power Project, United Kingdom
, 2020 The United Kingdom has been at the forefront of testing the feasibility of hot dry rock (HDR) geothermal energy resources since the mid-1970s. Several experiments were carried out between 1977 to 1991 at the Rosemanowes site in Cornwall.
