“…The desired level of geothermal power sustainability required in the European Union region could be achieved by increasing investment in human capital resources in the area of knowledge and skill in the geothermal energy sector. This supports the views of Mahbaz et al (2020); Cook et al (2020); Neves et al (2020); Mahbaz et al (2021); Aviles et al (2021); Tingting et al (2021). The implication of this is that geothermal power sustainable development at the micro-level can be assessed as being sustainable qualitatively from the view of improving community well-being.…”

“…The desired level of geothermal energy production of the EU14 nations could be attained by investing more in human capital resources in areas of skills and knowledge of those in the geothermal energy industry. This is in line with Mahbaz et al (2020); Cook et al (2020); Neves et al (2020); Mahbaz et al (2021); Aviles et al (2021); Tingting et al (2021). It means that a further boost in intellectual capital will aid the growth of geothermal power in the EU 14 countries.…”

“…In the same way, Aviles et al (2021) searched the potential of hybrid geothermal power integration with a desalination system, suggesting that low human capital costs can reduce the cost of electricity production and produce a significant increase in this value. Similarly, Tingting et al (2021) explored the geothermal power performance of a multiple-doublet system in Hot Sedimentary Aquifers, indicating that human input parameters in a multiple-doublet system significantly influence the fluid flow and heat transfer processes to achieve efficient geothermal power exploration. Under the governance regulation, many studies such as Britta et al (2020); Garcia-Gil et al (2020a); Garcia-Gil et al (2020b) developed integrated national energy and climate plans to cover the dimensions of the Energy Union related to decarburization, energy security, energy efficiency, internal energy market, research, innovation, and competitiveness.…”

There are many advantages of geothermal energy, as an environmentally friendly resource; however, for these benefits of geothermal power to be fully maximized, there are some problems that need to be addressed. The primary objective of this research was to examine the influence of intellectual property (IP) rights and economic growth on the geothermal energy output among the 27 European countries within the time frame 1990 to 2021. This study adopts auto-regressive distributed lag (ARDL). The findings show that a significant increase in the geothermal energy industry sustainability can occur in EU14 emerged economies using IP rights than in EU13 emerging economies. The major contributions of the research are that among additional factors, intellectual capital, market size, intuitional quality, and economic growth contribute more positively to geothermal energy sustainability in EU14 emerged economies than in EU13 emerging economies. Results from the analysis show geothermal power sustainability among the 27 European countries could be boosted significantly by adequately putting in place the determining factors of IP as this will foster the attainment of aims behind the energy union by the year 2030. This will no doubt be of help in curbing climate change and environmental pollution in society. The projected calculations were validated through the three estimators adopted for this study, that is, the pooled mean group, mean group, and dynamic fixed effect. The policy implication pointed out by this study the European nations in this study need to make IP indicators to be more effective as this helps in achieving societal and environmental goals. Moreover, the authorities in charge of lawmaking in European countries should focus more on IP areas to ensure the sustainability of geothermal energy generation. Also, authorities in charge of policymaking in the European nations should foster commixture strategies that are sustainable in enhancing IP breakdown as this will assist in fostering geothermal power exploration, thereby reducing the need for fossil fuels which will also carbon dioxide emission in the years to come.

“…Table 1 contains the information about the strata at various depths and their estimated thermal conductivities. The thermal conductivity of each stratum is determined by averaging the thermal conductivities of all the components, in accordance with the measured values of soils and rocks in the central Shaanxi plain by Ke et al [15]. The inlet and outlet temperature were monitored and recorded from December 16 to 23.…”

The optimal use of geothermal energy necessitates the performance evaluation and economic analysis of the geothermal heating systems. This work presented a field study of the long-term operating performance of a geothermal heating system in Xixian New Area, China. Nine deep coaxial ground heat exchangers (GHEs) with depths of 2,500 m were adopted for space heating to the residential buildings, with a total heating area and heating load of 136,097.71 m2 and 6,082 kW, respectively. The system’s 30-year running performance at various volumetric flow rates and operating modes was simulated. Through response surface analysis and multi-objective optimization, the levelized cost of energy (LCOE) and payback period were obtained based on the thermal performance analysis. It is concluded that the operating parameters have a significant impact on the system economy. When the daily operating time reduces from 24 hours to 8 hours, the payback period will be lowered from more than 25 years to approximately 11 years. When the volumetric flow rate is 35 m3·h-1, the examined system achieves the lowest LCOE. The minimum values of LCOE are 13.2 $/GJ, 11.6 $/GJ, 9.4 $/GJ, 7.8 $/GJ and 5.6 $/GJ when the system operates 24 hours (continuous operation), 20 hours, 16 hours, 12 hours and 8 hours a day, respectively. With the optimal flow rate, the average heat exchange rate of the single GHE increases from 295 kW to 519 kW after 30 years of operation when the daily operating time is reduced from 20 hours to 8 hours. The proposed method and findings can be used to guide the high-efficiency operation, which is conducive to reducing operating costs of geothermal heating systems.

“…Exploratory endeavors have ascertained that the sedimentary formations within the Weihe Basin have sufficient reserves of geothermal resources (Figure 1). The utilization of this resource is presently being employed on a considerable scale including heat pumps, bathing, and cultivation (Ke et al, 2021). Determining the geothermal genesis of this region is of great importance for the economic development of the area and can be applied to the discovery of its human and historical heritage.…”

The Weihe Basin, located in central China, stands out for its significant earthquake activity while concurrently harboring promising geothermal reservoirs. The potential association between these two geological occurrences and the underlying mechanisms remain enigmatic. Here, we compile a catalog of historic earthquakes, total strain data, data related to crustal mantle structure, surface heat flow data, and heat production data of the rocks in the Weihe Basin. Our aim is to unveil the intricate interplay among the occurrence of earthquakes, tectonic activity, and the genesis of geothermal resources. Our findings reveal that earthquake activity in the Weihe Basin is regulated by the responses of faults or fractures intricately influenced by regional tectonics. These tectonic processes are responsible for the formation of favorable geothermal resources beneath the basin. We propose there is a weak zone beneath the basin, which is controlled by a combination of tectonic processes and the flow of the asthenosphere. We finally establish a comprehensive model to visualize the genesis of the occurrence of earthquakes and the formation of geothermal resources. These results have important guiding significance for future research endeavors in the realms of both geothermal exploration and earthquake investigations within the Weihe Basin.
