Experiment, modeling and practice for safe and efficient developement of deep geothermal resource

The Paris Accord, which has been signed by many countries worldwide, specified that the world should achieve carbon neutral by 2050. Due to the rapid greenhouse gas emission, all we should look for net zero emission energy. Geothermal energy has been a promissing choise worldwide in different countries. The shallow geothermal energy is being extensively developed and utilized, while the heating scale of hydrothermal geothermal energy continues to expand, and the deep geothermal energy such as the hot dry rock is ongoing. The deep geothermal resources belongs to the most abundant and credible ones. Currently, we are in a key phase of seeking new theories, method and technology as well as piloting applications for development and utilization of deep geothermal energy. In the current issue we would like to present papers on deep geothermal resources including (but not limited to):

• Deep geothermal geology
• Deep geophysical exploration
• Deep geothermal drilling and borehole stability
• Deep geothermal reservoir characterization
• Deep geothermal heat extraction

We welcome experimental, numerical and engineering practice related to deep geothermal development, including theoretical research and distribution predictions, exploration methods and reservoir characterizations, geophysical explorations, as well as experimental technology, numerical modeling and development engineering. Aticle types of Original Research Papers, State-of-the Art Review, Commentary, Correspondence, or Short Communications are all welcome.
