About this Research Topic
The massive anthropogenic CO2 emissions have been causing global warming and a series of extreme weather and environmental problems. CO2 capture, utilization and storage (CCUS) have been regarded as one of the vital approaches for reducing CO2 emissions and achieving the Paris Climate Agreement. CO2 geological storage is considered an effective and safe approach for long-term CO2 storage by injecting CO2 into subsurface formations. Moreover, CO2 geological storage and utilization (CGSU) with enhanced subsurface energy and fluid extraction makes it more attractive considering the revenue from the oil, natural gas, coal-bed methane, geothermal energy, and brine production. The trapping mechanisms of CO2 are significantly different in various subsurface formations such as saline aquifers, oil/gas reservoirs, unmineable coalbeds and unconventional reservoirs (hydrate, shale). Good understandings of multiphase flow, reactive transport, and energy transfer of CO2 and subsurface fluids in these porous media are needed to guide the applications of CCUS.
Considering the relevant theories, experiments, and simulation studies are rapidly developing, this special issue focuses on the cutting-edge research and advanced technologies in CCUS with enhanced subsurface energy development. We aim to bring together Original Research and Review articles highlighting the recent advances in CGSU in new technologies, underlying mechanisms, advanced algorithms/modeling, innovative experiment methods, up-to-date field pilots, etc. Other studies on CCUS and the development of subsurface energy are also welcome.
Potential topics to be covered, but not limited to:
• CO2 storage with enhanced oil/gas recovery
• CO2 storage with enhanced coalbed methane
• CO2 storage in hydrate and CO2 / CH4 replacement in hydrate
• CO2 storage with enhanced geothermal energy, including dry hot rock energy
• CO2 storage with enhanced recovery of unconventional oil and gas (e.g. shale oil, shale gas)
• CO2 storage in saline aquifer with enhanced water recovery
• CO2 storage in deepwater formations
• Fundamental research on physical properties (such as PVT property, phase equilibrium, viscosity, etc.) of multi-component and multi-phase in CGSU
• Subsurface multiphase flow in CGSU
• Heat and mass transfer (such as diffusion, convective dispersion, adsorption/desorption, replacement in hydrate, etc.) in CGSU
• Multiphase pipeline flow in CGSU
• Artificial intelligence/machine learning application in CGSU
• Life cycle analysis of CGSU
• Techno-economic assessment of CGSU
• Other CCUS studies related to subsurface energy development
