In an a vertical well in granite at the Frontier Observatory for Research in Milford, Utah, USA, injection testing was carried out in three zones in 2017 and 2019. Inferred closure stresses from flowback studies are lower than those that were strictly shut-in. The rebound pressure is not necessarily the lower bound of the minimum principal stress, according to the numerical model. The transition from hydraulic fracture to natural fractures from numerical analysis can be characterized as the process in which the depletion transitions mainly transitions from hydraulic fracture to natural fractures.

This report will investigate how ICT, i. e. , information and communication technology factors with economic growth, has had on geothermal energy production in the selected 27 EU nations between 1990 and 2021. Autoregressive distributed lag was adopted, and the results show that a substantial rise in the geothermal energy industry's sustainability can occur in EU14 emerging economies using ICT technologies rather than in the 13 emerging economies. Likewise, recent studies indicate that a drastic decrease in carbon dioxide pollution can be achieved in EU13 emerging economies using more efficient energy production than in EU14 emerging economies. These findings reveal that geothermal power sustainability among the European Union countries could be dramatically enhanced if the number of ICT determinants rises to reach the 2030 energy union targets.

Geothermal potential in Indonesia can produce renewable energy 29 GW, and before 2016, it used 5% or 1643 MW. Every MWh electricity produced by LCI also showed that it needed 6. 87 Ton dry steam or 8. 16 Ton liquid steam to be effective. Potential value of 0. 155 Ton CO2eq. /MWh, Acidification Potential 1. 69 kg SO2eq. /MWh, Eutrophication Potential 5. 36 % eq. /MWh, Global Warming Potential is 0. 156 kg CO2eq. /MWh, Eutrophication Potential 1. 2 lakh PDF/m2 and land use impacts 0. 000024 PDF/m2. The Life Cycle Impact Assessment found that AP contribute 78% of environmental impact and 98% resulted from H2S Non Condensable Gas, with 98 percent contributing 98%. Key words: Life cycle Assessment; Geothermal; Continual Improvement; Global Warming Potential; Acidification Potential; and Biochemical Assurance; The difference between gross production, GWP, and AP value is shown by the comparison findings with another dry steam geothermal power plant, which show the company's potential results show that the company's effect could be strong, with a good position; Comparison results with another dry steam geothermal power plant show that a strong relationship exists between gross production, Geothermal.

Microgrid energy management and the inherent intermittency of high-penetrated renewable energy pose economic and reliable problems of microgrid energy management. This paper recommends the use of a two-layer predictive energy conservation device for high-renewable multi-generation microgrids. Because of their increasingly tight energy couplings and uncertain energy sources, the suggested microgrid multi-energy management is a challenging and cumbersome challenge. Simulation studies of a high-renewable MEM are used to demonstrate its efficiency and success over a single time scale model.

Geothermal energy is a renewable energy that can be used either directly or converted to other forms of energy. In Central Anatolia, the geothermal well with the highest well-bottom temperature was drilled, and the well-bottom temperature was recorded at 341°C at a depth of 3845 meters. According to Tu00fcrkiye's electricity generation capacity and total installed direct heat use in 2022, the total installed direct heat use reached 1663 MWe and 5113 MWt, respectively. Enhanced Deep Geothermal Systems, for example, the total granitoid area of Western Anatolia is 4221 km2, but at least 2% of this granitoid can produce 8x107 MWh of electricity.

In local geological conditions, it is highly recommended to investigate the possibility of converting abandoned oil/gas wells into geothermal energy production wells. This model simulates the heat transfer from the geothermal zone through the wellbore to the surface wellhead, considering pipe and wellbore insulation. The temperature of the returning fluid is similar to that of the injected fluid without pipe insulation, according to findings. The deliverable fluid temperature can be increased from 30 °C to 124 °C for a system with a thermal conductivity of insulation pipe Kp = 0. 3 W/m-C. Increasing the length of the horizontal wellbore in the geothermal zone from 2000 m to 8000 m can raise the temperature of the returning fluid from 148 °C to 159 °C.

Renewable energy use has sparked a research boom, and an increasing number of nations have expressed enthusiasm for the exceptional use of geothermal energy in urban heating and power generation. The development of geothermal energy has increased strategic importance for RCEP countries, prompting renewed calls for the integration and upgrade of existing environmental resource cooperation platforms in the region.

Krakow has a large district heating network, which is about 900 km long. Two reservoirs, namely Devonian and Upper Jurassic, are mainly composed of dolomite and limestone, and the potential of deep geothermal waters are based on two reservoirs built of carbonate rocks. According to 3. 3 and 2. 0 MW, respectively, the theoretical potential of water intake equal to a geothermal installation's nominal heating capacity is estimated. The city's complicated geological system makes it difficult to assess. Shallow geothermal energy potential varies within the region, reflecting the city's complex geological geology. The shallower water levels could be a significant potential source for both heating and cooling by means of water heat pumps, unlike traditional borehole heat exchangers. A photovoltaic system can be a cost-effective and sufficient source of electricity that can meet the heat pump installation's annual electricity demand when it is used for both heating and cooling in the case of balancing production and demand.

This paper provides a comprehensive review of scientific findings, regulatory frameworks, technological advancements, and commercial trends related to the integration of shallow geothermal energy technologies in modern 5th-generation district heating and cooling networks. In this sense, decarbonization of the heating and cooling sector is a crucial piece of the energy transition puzzle, in the hope of keeping global warming below the critical threshold of 1. 5 %u00b0C by the next century. In addition, the Ukraine war has given urgency to end up with fossil fuel dependency. The most significant result of this literature review is the synergistic interaction between SGE, 5GDHC networks, and urban environments. SGE systems and DHC networks of any kind are particularly poor deployment in Mediterranean countries, with SGE systems and DHC networks of any kind showing a particularly low deployment relative to the rest of Europe.

Ascertaining their effectiveness in making critical decisions on a proposed development action is vital. In this paper, we present the findings of an investigation into the quality of fifteen ESISs for Kenya's geothermal energy resource projects from 1994 to 2019. The analysis, which was based on the Lee and Colley Review Package, involved a systematic analysis of how well a number of assessment tasks were carried out in four study areas, 13 categories, and 40 subcategories. The subcategory assessment findings and the ESIS's most useful information were then used to define the review category. The findings of the review process were used to assess each review area of the ESIS. Eighty percent were of high quality in the study phase of the development and baseline conditions, while 60% were of high quality in the evaluation area of the impact statement's presentation. In the investigation area of the environmental and social management plan and follow-up, six percent were of very poor quality. Impact assessment and evaluation of alternatives, impact identification and analysis of alternatives, and environmental and social management policies can be addressed by targeted training of Impact Assessment Practitioners, as well as legislative amendments on public participation.
