“…In present study geothermal potential exploration of the Ağrı province was performed using GIS based Fuzzy AHP method. Five different criteria were determined taken into consideration characteristics of the study area and also international literature (Yousefi et al, 2007;Yousefi et al, 2010;Tüfekçi et al, 2010;Noorollahi et al, 2015;Yalçın and Gül, 2017;Macharia et al, 2018;Cambazoğlu et al, 2019, Abuzied et al, 2020Meng et al, 2021). Geological formations, hot / mineral springs, lineaments, land surface temperature and hydrothermal alteration zones were analyzed to detect the presence of potential geothermal resources in the study area.…”

“…For this reason, it is extremely important for the determination of geothermal resources. It has been analyzed as one of the most important criteria in many geothermal resource exploration studies conducted in the literature and it has been determined that the geothermal potential is high in areas close to these fracture zones (Hanano, 2000;Yousefi et al, 2010;Cambazoğlu et al, 2019;Meng et al, 2021). In present study, the lineament map of the study area was prepared using Landsat 8 OLI/TIRS satellite images.…”

“…Geothermal energy is frequently used today in energy, heating and cooling processes where electrical production and district heating and cooling applications are required. In addition, some industrial applications requiring drying, in the production of chemicals such as fertilizer, lithium, hydrogen or carbon dioxide, in the tourism sector and in the production of mineral drinking water (Teke and Yaşar, 2018;Yan et al, 2017;Wang et al, 2018;Meng et al, 2021). The most important advantage of geothermal is that it is a renewable energy source.…”

“…Thus, it is possible to determine the potential of very large areas in a short time and economically. GIS-based multi-criteria decision-making analyzes are used by different researchers in the exploration of geothermal resources in our country as well as in the world (Tüfekçi et al, 2010;Noorollahi et al, 2015;Yalçın and Gül, 2017;Cambazoğlu et al, 2019;Abuzied et al, 2020;Brahim et al, 2020;Bilić et al, 2020;Meng et al, 2021).…”

The demand for energy is increasing day by day worldwide due to population growth, industrialization and rising living standards. Geothermal energy, one of the alternative energy sources, is preferred in terms of providing environmentally friendly, quality and regular energy.Our country is rich in geothermal resource potential. However, there are still many unexplored geothermal resources. In this study, fuzzy-AHP method was used to determine the geothermal potential of Ağrı province. Five criteria such as geological formations, hot / mineral springs, lineaments, land surface temperature and hydrothermal alteration zones were evaluated to determine the having geothermal potential. The maps of lineament, land surface temperature and hydrothermal alteration zones were prepared using Landsat 8 OLI/TIRS satellite images.Each criterion was weighted with the fuzzy-AHP method, analyzed in the GIS environment, and the geothermal potential index (GPI) of the study area was calculated. As a result, areas with very high, high, medium and low geothermal potential were determined in the study area.According to the GPI map of the study area, Ağrı provincial center, Patnos, Eleşkirt and Doğubayazıt regions have high geothermal potential. In addition, the known geothermal fields in the study area have been identified as areas with very high geothermal potential. These data reveal the accuracy of the study and used method.

“…Geothermal power plants are built around plate tectonics where high-temperature geothermal sources are available near the surface [6]- [8]. Developments and refinements in drilling and extraction technology have expanded the range of geothermal power plant construction from nearby tectonic plates [9], [10]. The thermal efficiency of geothermal power plants tends to be low because the fluid is at a lower temperature compared to steam or boiling water [11], [12].…”

Measurement of fluid level in steam valves should require precise values. The instrument designed in this article is used to find out how precise the limit switch is used as an indicator control valve at certain points. The measurement technique will be implemented on a control valve on the geothermal power plant. This device is using the Arduino Due board as a data processor and modified the data signal of the vernier caliper to measure the valve opening. The TFT LCD layer is used to display the measurement and calibration results. The test results of this device indicate that this device has an accuracy level of more than 99%.

The spatial prediction of geothermal sites along the southeast side of Taihang Mountain in the Tangyin rift is a critical goal in the development of renewable energy resources in cities such as Hebi in Henan province, which has significant potential for geothermal energy production due to the existence of deep faults and Cenozoic volcano. The study aimed to delineate areas with high geothermal manifestations for detailed geothermal exploration and well-test drilling. To define favorable zones for geothermal potentiality, multi-source datasets were chosen to generate evidence thematic layers that demonstrate the distribution of geothermal anomalies such as geologic maps, structural maps, Land Surface Temperature maps (LST), and hydrothermal mineral alterations maps. The remote sensing and Geographical Information System (GIS) approaches were integrated to map fossil geothermal manifestations and appraise the promising geothermal zones from Landsat 8 OLI/TIRS and Advanced Spaceborne Thermal Emission and Reflection Radiometer-Digital Elevation Model (ASTER-DEM) dataset using the Analytic Hierarchy Process (AHP), which is one of the Mult-criteria Decision Making methods. Results show LST values ranging from 22.6°C to 45.4°C, with the highest values found along the faults and volcanic areas. The hydrothermal alteration minerals discriminated from band ratios of 4/2, 6/5, and 6/7 for iron oxide, ferrous minerals, and clays reveal the presence of high amount of montmorillonite and illite minerals along the faults and volcanoes which are related to hot fluid circulation from subsurface. Structural analysis shows that the major structural trend follows the NNE Tangdong and Tangxi faults, with high density on the west side of the Tangxi fault where there is good exposure of outcrop but less fault density on the east side due to sedimentation in a low land which may conceal geological structures. Lastly, all the thematic layers of geothermal factors were reclassified, ranked, and integrated by the weight overlay logic model based on the influence of geothermal suitability to map potential areas for geothermal resources whereby 5 zones were obtained ranging from very poor to very good. The promising potential sites are mostly found along the highly deep structures of the major Tangxi fault crosscutting the permeable lithology of carbonate rocks and around the Hebi volcanoes. The distribution of hot springs and geothermal wells of the Hebi field were correlated and verified against the potential geothermal anomalies map. The overall integrated method proposes an advanced technique for designing the Tangyin rift’s exploration plan and development actions for geothermal resources utilization, which can be used for exploration of any unveiling geothermal potential sites.
