The SEHRENE project represented by University of Liege team participated in the in Carnot 2024: Belgian Symposium of Thermodynamics, celebrating 200 years since Sadi Carnot’s groundbreaking work, Reflections on the M
otive Power of Fire, which established the 2nd Law of Thermodynamics. This event, held from December 16-18, 2024, at Université de Liège, Belgium, explored the role of thermodynamics in energy transition in the academia and industry. Highlights include keynote speeches, research presentations, poster sessions, industrial sessions, and networking opportunities. Topics span non-equilibrium thermodynamics, HVAC&R, carbon capture, energy storage, and energy transition scenarios.
University of Liege and Zorlu Enerji teams showcased its latest research in heat pumps, energy systems, and fluid properties through poster presentations and engage in discussions on cutting-edge ideas to advance sustainable energy solutions. One featured poster, “Carnot Battery Integration in a Geothermal Power Plant: Study Case of Zorlu Enerji,” presented an innovative Electro-Thermal Energy Storage (ETES) system. This study examined the implementation of a Carnot battery at the 80MW Kızıldere-II geothermal plant in Türkiye. The system integrates a High-Temperature Heat Pump (HTHP), Phase Change Material (PCM) storage, and an Organic Rankine Cycle (ORC) by using waste heat from re-injection wells and cooling water from the plant to enhance energy efficiency and reduce greenhouse gas emissions.
The poster further explored architecture selection, refrigerant evaluation, and future plans for the system. Among proposed architectures, the PRE configuration was chosen for its optimal trade-off between Round-Trip Efficiency (RTE) and output power. Cyclopentane emerged as the preferred refrigerant due to its balance of performance and cost. The study sets the stage for detailed component sizing, dynamic system analysis, and energy management advancements, highlighting the transformative potential of thermodynamics in industrial applications.
