COVID-19 and impact on peer review

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.

Call for papers: On the future development of superhot and supercritical geothermal systems

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.

Aims and scope

Geothermal Energy – Science, Society and Technology focuses on fundamental and applied research needed to deploy technologies for developing and integrating geothermal energy as one key element in the future energy portfolio. Contributions include geological, geophysical, and geochemical studies, exploration of geothermal fields, reservoir characterization and modeling, development of productivity-enhancing methods, and approaches to achieve robust and economic plant operation. Geothermal EnergyScience, Society and Technology serves to examine the interaction of individual system components while taking the whole process into account, from the development of the reservoir to the economic provision of geothermal energy.
