When considering the development of a geothermal project, the complex task of synthesizing and quantifying the influencing factors and their interactions is inevitable, allowing a comprehensive assessment of the use of the geothermal energy. geothermal energy in different ways. The main objective of the scientific work is a revised set of criteria for comprehensive evaluation of a geothermal project focusing on Enhanced Geothermal Systems (EGS) and taking into account geological, technological and, economic and financial aspects of the development project and social and environmental parameters. The newly presented work is designed as a supplement to previous work, identifying and describing in detail twenty-eight factors influencing the assessment of deep geothermal energy. The elements mentioned include the newly introduced 18, 6 superseded and 4 revised criteria based on extensive literature review and expertise integrating all aspects of the development process. EGS project. One of the main conclusions of the method presented is that it provides a broad assessment of an EGS project, applicable to various end-uses, including electricity generation only, heat production only and combine the production of heat and electricity. The proposed methodology can serve as a preparatory guide for more detailed analysis and calculations for the development of a future project, be it a wilderness area or a field. brown, including technology, geology, economy and environment. This approach was tested in a case study in which two different geothermal sites were evaluated for heat generation and power generation scenarios. The two sites, with their key geological parameters, generated electricity production from 263.51 GWh to 927.69 GWh, and heat production from 334.25 GWh to 5,207.68 GWh. This increase in renewable energy production from geothermal sources has avoided CO2 emissions from 79,686 tons CO2eq to 1,241,542 tons CO2eq. The final score for each criterion for power and heat generation scenarios is in favor of Score 2, where better reservoir and economic performance values lead to the highest final score for the overall performance of the score. The combined results lead to the conclusion that the proposed methodology is applicable to evaluate end-use options for a geothermal site and to compare projects at other geothermal sites together.
