Special Issue Information

Dear Colleagues,

Geothermal energy has emerged as a critical component of the global transition to a sustainable and secure energy future. As a green, sustainable, and renewable alternative, it holds significant potential for reducing carbon emissions, enhancing energy diversity, and supporting industrial and residential heating, cooling, and power generation. Nevertheless, large-scale and efficient utilization of geothermal energy remains challenged by complex geological conditions, the high cost and technical difficulties of deep drilling, and the need for innovative reservoir management techniques to ensure efficiency and economic viability. Recent progress in geothermal exploration, development, and utilization has opened new frontiers, demanding a concerted effort to bridge theoretical research, technological innovation, and practical application.

This Special Issue aims at showcasing recent advances and emerging trends across the full spectrum of geothermal research, including theoretical modelling, exploration technologies, resource assessment methodologies, practical applications, operational strategies, and field case studies. Submissions of original research articles, short communications, and comprehensive reviews are warmly welcomed.

Topics of interest for publication include, but are not limited to, the following:

  • Resources exploration and assessment;
  • Advanced drilling and geothermal well engineering;
  • Enhanced geothermal systems;
  • Geothermal reservoir simulation and forecasting;
  • Scaling, corrosion, and material durability of geothermal heat exchangers;
  • Power generation technologies;
  • Heating, cooling, and storage;
  • Geothermal coupled applications;
  • Socio-economic and risk assessment of geothermal plants;
  • Policy, regulation, and market mechanisms of geothermal energy.

Magma-heated geothermal systems have garnered significant attention in academia due to their unique formation mechanisms and vast potential. This paper focuses on the Rehai, Ruidian, and Banglazhang geothermal fields in the Tengchong area. We present the element geochemistry and isotope compositions of hot springs, cold springs, and surface water to explore magmatic fluid input into geothermal systems and investigate the release of deep mantle-derived components. Based on our findings, we propose a conceptual model and theoretical framework for geothermal system genesis constrained by magmatic heat source influences. Results indicate that magma-heated geothermal systems coexist with three types of geothermal water: neutral chloride-rich water, acidic sulfate-rich water, and alkaline bicarbonate-rich water. The infusion of magmatic fluids into geothermal systems. The enrichment of trace elements in hot springs is jointly controlled by magmatic fluid input and host rock leaching. The magma chamber is the primary factor influencing the reservoir temperature. The parent geothermal fluid can be identified within the geothermal system. During circulation, the parent geothermal fluid undergoes three cooling processes: adiabatic cooling, conductive cooling, and mixing with cold water. We propose that the release of mantle-derived materials is a key factor in element enrichment within magma-heated geothermal systems, and mantle-derived components are more enriched in areas with active magma chambers. The findings of this study provide insights into magmatic fluid input into geothermal systems and highlight the critical role of the release of mantle-derived components in the formation of high-temperature geothermal resources.
