Summary
Driven by carbon neutrality goals and clean energy transition, deep geological technologies including carbon capture, utilization, and storage (CCUS), geological hydrogen storage, and underground energy storage have emerged as essential solutions for carbon reduction, low-carbon fossil energy upgrading, and large-scale new energy consumption. Recent advances in secure CO2 sequestration, tight-reservoir hydrogen storage, CO2-enhanced energy storage, and multi-field stability evaluation have verified the great potential of deep geological reservoirs for large-scale carbon and energy storage applications. Key research frontiers cover multi-physical coupling mechanisms, geomechanical stability, pore-throat evolution, fluid–rock interactions, and long-term storage safety, with continuous innovations in reservoir characterization, numerical simulation, site assessment, risk prediction, and engineering optimization. This Special Issue aims to collect original research and review articles reporting novel theories, methods, and technological progress in deep geological CCUS, hydrogen storage, and underground energy storage.
Potential topics include, but are not limited to, the following:
1. Advanced characterization methods and evaluation technologies for petrophysical and geomechanical properties of deep storage reservoirs for CCUS and hydrogen storage;
2. Formation conditions, reservoir optimization, and site screening criteria for deep geological carbon sequestration and underground hydrogen storage;
3. Diagenetic control, pore evolution, and storage capacity evaluation of deep saline aquifers and abandoned hydrocarbon reservoirs;
4. Fluid–rock interaction, multi-field coupling mechanisms, and storage security evaluation during CO2 and hydrogen geological storage;
5. Engineering case studies, technological innovations, and industrial application prospects of deep CCUS, geological hydrogen storage, and underground energy storage projects.
