Ali Eyvazi is a researcher in the field of clean and sustainable energy systems, currently affiliated with the Department of Mechanical Engineering at Vali-e-Asr University, Iran, with expertise focused on energy, hydrogen production, exergy evaluation, geothermal systems, and economic optimization of advanced multigeneration technologies. His research portfolio centers on the development and thermoeconomic assessment of novel multigeneration energy systems that simultaneously produce power, heating, cooling, and liquid hydrogen, typically by incorporating geothermal resources, gas turbines, absorption heat transformers, ejector cooling, and compressed air energy storage technologies. Eyvazi’s works adopt a holistic performance evaluation framework that includes energy, exergy, and cost analyses, often coupled with optimization methods to identify thermodynamically efficient and economically viable configurations. His 2025 publications prominently explore geothermal-based multigeneration cycles, including innovative cascade methods for hydrogen liquefaction and combined precooling processes (e.g., Claude hydrogen liquefaction integrated with helium-based Joule-Brayton cycles). He frequently collaborates with experienced co-authors such as Mehran Ameri, Mohammad Shafiey Dehaj, and Hadi Ghaebi, contributing to multiple reputable journals in heat and mass transfer, sustainable energy systems, and process integration. His studies aim to reduce reliance on fossil fuels and improve the practicality of hydrogen as a clean fuel, particularly by lowering energy consumption during liquefaction and enhancing heat recovery mechanisms. Alongside optimization-driven geothermal designs, his research also examines hybrid systems combining gas turbines with absorption chillers, as well as environmentally safer cooling systems utilizing sulfur dioxide-based ejector technology. These contributions support the advancement of renewable energy integration and more efficient energy conversion methods for future smart grid applications. Although his scientific metrics are at an early stage — with 1 citation, h-index 1, and i10-index 0 — his rapidly growing publication record between 2024 and 2025 (more than 15 articles) highlights strong academic productivity and continued engagement with emerging topics in global decarbonization efforts. Eyvazi’s overall objective is to address global energy sustainability challenges through high-efficiency thermal systems, providing economically optimized solutions for clean hydrogen generation and multi-output energy plants that can support industrial and societal needs in the evolving renewable energy landscape.
