This postdoctoral researcher models hydrogen production systems to optimize renewable energy performance.
Mohammad Sabbaghi is a postdoctoral researcher in the field of renewable energy systems at Dokuz Eylul University. In this Postdoc Portrait, he reflects on his ongoing research, the fulfillment he finds in mentoring students, and his commitment to advancing the global energy transition.
Q | How did you first get interested in science?
My interest began during my undergraduate years, when I became fascinated by the potential of renewable energy technologies to address global environmental and energy challenges. The more I learned about the fundamental principles of thermodynamics and energy conversion, the more motivated I became to explore innovative solutions for sustainable energy systems. During my graduate studies, I was introduced to hydrogen technologies and fuel cells, which combined both theoretical depth and practical significance. The idea of producing clean energy while simultaneously reducing carbon emissions deeply resonated with my values.
Q | How did you first get interested in your field of research?
Over time, I realized that energy research is not merely about developing technical solutions but also about creating pathways toward a more sustainable society. This realization encouraged me to pursue my doctoral research, where I focused on renewable-driven hydrogen production and optimization of energy systems. My passion continues to grow as I see how scientific research can shape real-world applications and contribute meaningfully to global energy transitions.
Q | Tell us about your favorite research project you’re working on.
One of my favorite research projects involves the development of a hybrid multi-generation system that integrates a modified Organic Rankine Cycle with hydrogen production through a proton exchange membrane (PEM) electrolyzer. The system not only produces electricity but also provides heating, cooling, and hydrogen fuel, making it highly versatile and sustainable. What excites me most about this project is its multidisciplinary nature. It requires knowledge of thermodynamics, electrochemistry, optimization techniques, and environmental analysis. Additionally, the project allowed me to implement the “6E” approach, analyzing the system from energy, exergy, emergy, economic, environmental, and risk viewpoints. This holistic framework provided valuable insights into how advanced renewable systems can be designed for both technical efficiency and socio-economic feasibility. Beyond the technical outcomes, the project was rewarding because it engaged students in laboratory innovation, where we collaboratively designed equipment to test and improve system components. It remains a milestone in my career, combining theory, experimentation, and teamwork.
Q | What has been the most exciting part of your scientific journey so far?
The most exciting part of my scientific journey has been witnessing the impact of my research and collaborations on both academic and practical levels. Publishing as a first author in international journals and collaborating with distinguished professors from Canada, Turkey, and the United Kingdom provided me with valuable exposure and confidence. Another highlight was mentoring graduate students during my postdoctoral work, guiding them to successfully complete their theses and gain confidence in independent research. Equally exciting was contributing to the development of new laboratory equipment by working alongside my students. This collaborative innovation not only improved our research capabilities but also offered students hands-on experience in engineering problem-solving. Additionally, serving as a reviewer for high-ranking journals and as a member of an editorial board has been particularly rewarding, as it allows me to stay connected with the forefront of scientific progress.
Q | If you could be a laboratory instrument, which one would you be and why?
I would be a fuel cell test station. A test station brings together multiple disciplines, such as thermodynamics, electrochemistry, and systems engineering, while serving as a bridge between theory and application. Much like my own research career, it operates at the intersection of experimentation and analysis, continuously measuring, adjusting, and optimizing performance. What makes this issue appealing is that a test station not only measures outcomes but also inspires improvements, enabling researchers to design more efficient and sustainable systems.
