The reserves of hot dry rock (HDR) geothermal resources are huge. main method used to develop HDR is called an enhanced system (EGS), and this generally uses hydraulic fracturing. After nearly 50 years research development, more countries have joined the ranks engaged in exploration development world. This paper summarizes base technologies, key game-changing technologies promote commercialization resources. According present situation exploration, utilization at home abroad, evaluation site selection, efficient low-cost drilling, defined as technologies. Key include high-resolution characterization HDR, complex fracture network reservoir creation, effective microseismic control, connectivity, characterization. Game-changing downhole liquid explosion in-situ heat transfer power generation, use CO2 other working fluids for high-efficient generation. Most already industrial applications, but future efforts must focus on reducing costs. majority still demonstration validation phase not yet been applied scale. However, breakthroughs cost reduction application effectiveness urgently needed these remain laboratory stage, any area could significantly advance In addition, we conducted a comparative analysis respective advantages China United States some development. On basis, summarized challenges identified throughout discussion highlighted most pressing priorities. We hope can guide new countries, helping establish batch exploitation areas. look forward fostering collaboration between through technical comparisons, jointly promoting commercial
