Synergizing wind turbines with geothermal heat pumps: An exergoeconomic performance and optimization study

This study meticulously evaluates a hybrid renewable energy system that integrates geothermal heat pumps with wind turbines, focusing on Ciudad Juarez, Mexico. Utilizing statistical and mathematical analysis, the research delves into the energy, exergy, and exergoeconomic performance of the system, emphasizing its sustainability and efficiency. A standout result is the ground-source heat pump's coefficient of performance, which remains stable at 3.916 across varying ambient temperatures, showcasing the system's resilience. A significant observation is the inverse relationship between the system's exergy efficiency and ambient temperature, highlighting efficiency loss at higher temperatures. Among the system components, the wind turbine distinguished itself with a 100% exergoeconomic factor, signifying its paramount efficiency in energy conversion without exergy loss, underscoring the wind turbine's critical role in sustainable energy generation. The study also uncovers a consistent net power output of 9.765 kW, demonstrating the system's reliability amidst temperature variances. The exergoeconomic analysis reveals disparities in component efficiencies, marking the ground source heat exchanger and condenser as areas ripe for optimization to enhance the overall system performance. Future research is suggested to expand climatic condition variations and explore adaptive system designs, aiming to improve the hybrid system's efficiency and global applicability, thereby enriching the renewable energy domain.
