Berlin, Germany
Professor Tetyana Morozyuk is the head of the department “Exergy-Based Methods for Refrigeration Systems” at Technische Universität Berlin, Germany (since 2013). In 1990, she received her Diploma, in 1994 her Ph.D., and in 2001 the Doctor Habilitatus Degree and Professorship, all in Ukraine. She supervised/co-supervised 20 Ph.D. and more than 100 M.Sc theses. 20 more Ph.D. candidates are on their way to completing the PH.D. thesis under the supervision of Prof. Morozyuk. She published 8 books, more than 400 research papers, and has 10 patents. Since 2015, she serves as a study dean for the International Master program “Process, Energy, and Environmental System Engineering”. Since 2021, she is the Director of the Institute for Energy Engineering, TU Berlin. Tetyana Morozyuk is the first female recipient of the James Harry Potter Gold Medal from the American Society of Mechanical Engineers (ASME) for outstanding and innovative contributions to the science of theoretical and applied thermodynamics, particularly eminent teaching and research in the areas of advanced exergy‐based methods, refrigeration and cryogenic processes, and electric power generation plants Since 2022, she is the Editor-in-Chief of the Journal of Energy Resources Technology, ASME digital collection.
Hydrogen technologies and Power-to-X: State of the art and multicriteria evaluation
Power-to-X become a broad concept that describes a range of technologies aiming to convert “Power” (electrical power regardless of the source) into other forms of energy or e-fuels, i.e. "X". This innovative concept plays a crucial role in addressing the challenges of renewable energy integration, energy storage, and the decarburization of various sectors. A key aspect of Power-to-X is water electrolysis. The produced hydrogen can then be further used in different ways. Hydrogen can be directly used as a clean fuel for transportation, industrial processes, or power generation. Alternatively, hydrogen and carbon dioxide through various processes can be converted to e-fuels, including methane or liquid hydrocarbons. The versatility of Power-to-X technologies positions them as potential game-changers in the efforts to create a sustainable energy sector. They not only contribute to energy storage and grid stability but also offer avenues for reducing carbon emissions in sectors that are traditionally hard to electrify. As the global community intensifies its focus on reducing greenhouse gas emissions, Power-to-X emerges as a promising tool in the transition towards a more resilient, low-carbon future.
