Abstract

Abstract This study investigates the sustainable utilization of CO2 for energy extraction from geothermal reservoirs. Geothermal energy is a reliable and renewable source, but its efficiency can be enhanced through innovative approaches. The concept of utilizing CO2 as a working fluid in geothermal systems holds promise due to its favorable thermodynamic properties and potential for CO2 capture and storage. This research aims to explore the feasibility and benefits of using CO2 for energy extraction from geothermal reservoirs. The study combines theoretical modeling and numerical simulations to assess the performance of CO2-based geothermal systems. A conceptual framework is developed, considering the thermodynamic behavior of CO2 and its interactions with the subsurface reservoir. The simulations involve reservoir characterization, fluid flow analysis, and heat transfer calculations, taking into account various operational parameters and system configurations. The results demonstrate the potential of utilizing CO2 for energy extraction from geothermal reservoirs. The simulations reveal enhanced heat transfer efficiency and increased power generation when compared to traditional geothermal systems. The utilization of CO2 as a working fluid facilitates higher thermal efficiencies, lower greenhouse gas emissions, and improved overall system performance. The results also highlight the importance of proper reservoir characterization and operational optimization for maximizing energy extraction potential. The findings of this study emphasize the sustainable and efficient utilization of CO2 for energy extraction in geothermal systems. By employing CO2 as a working fluid, geothermal power generation can be significantly enhanced, contributing to a more sustainable and carbon-neutral energy sector. The outcomes of this research provide insights into the technical feasibility and environmental advantages of CO2-based geothermal systems, serving as a basis for further development and implementation of this innovative approach. The study contributes to the ongoing efforts in harnessing renewable energy sources and reducing carbon emissions, advancing the field of geothermal energy and promoting a sustainable energy transition.
