As a result of the significant disruption that is being caused by the COVID-19 pandemic we are very aware that many researchers will have difficulty in meeting the timelines associated with our peer review process during normal times. Please do let us know if you need additional time. Our systems will continue to remind you of the original timelines but we intend to be highly flexible at this time.
COVID-19 and impact on peer review
The development of high-temperature geothermal fields with supercritical conditions are emerging as a new hot topic in various parts of the world since a significantly higher power output seems feasible with less drilling required.
Featured article: The potential of coupled carbon storage and geothermal extraction in a CO2-enhanced geothermal system: a review
The increasing demand for energy makes it difficult to replace fossil fuels with low-carbon energy sources in the short term, and the large amount of CO2 emitted by fossil fuel combustion increases global warming. Carbon capture and storage (CCS) technologies for reducing CO2 emissions in power plants and industrial processes have been developed. High costs and security issues limit industrial applications of these technologies, so an alternative for carbon reduction is needed, i.e., CO2 as a working fluid for coupled carbon storage and geothermal extraction in an Enhanced Geothermal System (EGS). We describe the status of global carbon emissions, CCS technologies, and their challenges. The characteristics of CO2 as a working fluid are compared from thermophysical and thermodynamic perspectives, and the solubility of CO2 in reservoir fluids with different ionic strengths, pressures, and temperatures is analyzed. The influence of artificial stimulation on the permeability of an EGS reservoir is described. Through heat extraction experiment of water alternating supercritical CO2 (SCCO2) cycle injection, the effects of CO2–fluid–rock interactions on the reservoir’s structure and of mineral dissolution and precipitation on geological CO2 storage are analyzed. We summarize the application prospects for this alternative and the challenges of future application.
