SIGN UPPlenary Session 1 — Keynote speakers
Monday, May 12th 10:30—11:30
Sustainable Refrigeration as an Opportunity for Society and Climate
Yosr Allouche
Director General
International Institute of Refrigeration (IIR) — FRANCE
Dr. Eng. Yosr Allouche is the General Director of the International Institute of Refrigeration (IIR), having assumed the role in October 2024. She holds a PhD in Mechanical Engineering and is recognised for her expertise in the energy performance of CO2 transcritical systems in hot climates and PCM (Phase Change Material) energy storage. Dr. Allouche gained recognition as a research scientist in refrigeration technology at the Norwegian University of Science and Technology (NTNU), where she has also served as a visiting Associate Professor in Refrigeration since 2021. She has authored numerous publications in scientific journals, guides, and policy documents.
Numerical Assessment of the Rough Reservoir Development as an UK Intra-Seasonal Hydrogen Storage Facility
Zuansi Cai
Associate Professor
Edinburgh Napier University — UNITED KINGDOM
Dr. Zuansi Cai is an Associate Professor of Energy and Environmental Engineering and a member of the UK EPSRC Peer Review College in energy storage. He is a recipient of The Royal Academy of Engineering Industrial Fellowship 2021/22. Zuansi has a track record of research excellence, including funding, publication and impact. He had published 50+ high impact journal paper (H-index=20, >1300 citations since 2019) in energy storage, renewable energy, etc. Recently, he has developed a novel numerical simulator with parallel computing capability. The simulator (GPSFLOW) is capable of simulating heat transfer, multi-phase and multi-component flow in pore media. The simulator has been recently used by Centrica to assess the performance of the Rough gas reservoir as hydrogen and gas mixture storage facility for zero emission energy transition.
Plenary Session 2 — Keynote speakers
Monday, May 12th 14:00—15:00
Hydrogen as a Vector for the Transition to a Clean Energy and Transport Sector
Magdalena Dudek
Professor
AGH University of Krakow — POLAND
Magdalena Dudek is a Professor in the Department of Sustainable Energy Development at AGH University of Krakow. She is engaged in teaching and research in the interdisciplinary fields of energy efficiency, integrated power sources involving renewable energy, hydrogen technologies, fuel cells and electrochemical devices. Prof. Dudek is the author or co-author of over 100 scientific and technical papers. She is included in the top 2% of research scientists on the Elsevier and Stanford University lists. She also holds ten patents in the area of hydrogen and fuel cells. With more than 20 years of experience in the energy and fuels market, particularly in the hydrogen economy and fuel cell technology, Prof. Dudek’s contributions to industrial cooperation have been recognised with special awards at international and Polish exhibitions. Additionally, she has been involved in research programmes funded by the European Union, the European Institute of Technology, UNESCO and national research frameworks in Poland.
Workshop 2
Tuesday, May 13th 12:00—13:00
Applications of Exhaust Air Heat Pumps in Nearly and Net-Zero Energy Buildings
Ivan Dimchev
Senior Assistant Professor
Technical University of Sofia
The purpose of the workshop is to present the applications of exhaust air heat pumps (EAHPs) in the context of nearly zero-energy buildings (nZEB) and net-zero energy buildings (ZEB). The workshop focuses on the integration of EAHPs into HVAC systems, emphasizing their role in achieving high energy efficiency. Particular attention will be given to the alignment of EAHP performance with national regulations derived from the EU's Energy Performance of Buildings Directive. Practical considerations for design, system selection, and adaptation to local climate conditions will be discussed, along with relevant case studies and system performance parameters.
