Dr.-Eng. Angelo Freni graduated in Materials Engineering at the University of Messina in 1998. He holds a Ph.D. in Materials and Chemical engineering from the University of Messina. He has been at the Italian National Council of Research - Institute for Advanced Energy Technologies (CNR-ITAE), Messina, since 1998. He has worked on thermally-driven heat pumps, heat and hydrogen storage, has published more than 130 printed papers in the field, plus 3 patents. He has been carrying out and leading scientific activities in the framework of National and International programs, in co-operation with industries and research groups. Currently, he is Head of the research group on "Thermally Driven Heat Pumps" at CNR ITAE. He is the Italian alternate delegate in the Executive Committee of the Heat Pump Programme of the International Energy Agency. He is member of the commission "E2 - Heat pumps, energy recovery" of the IIR - International Institute of Refrigeration. Dr.-Eng. Belal Dawoud graduated and got his M.Sc. degree in mechanical power engineering at the Faculty of Engineering, El-Menoufiya University, Egypt in 1993. He received his Dr.-Ing. Degree in energy engineering from RWTH-Aachen University, Germany in 1999. Till December 2005, he worked as a post doctor and research group leader for thermal applications of solar and sorption technologies at the institute of technical thermodynamics of RWTH-Aachen University. He has been an ASHRAE-Member since 2005 and since January 2006 he has been working at the Viessmann Werke in Allendorf/Eder, Germany as a project leader, group leader and since 2009 as a manager of research and development of thermally driven heat pumps (TDHPs). He published a book (VDI project final report) on the development of a gas driven zeolite adsorption heat pump in 2011 and more than 34 printed papers in the fields of adsorption and absorption heat pumps as well as greenhouse desalination and energy systems' analysis. In addition he has filed 34 patents in the field of TDHPs. He has been carrying out and leading scientific activities in the framework of National and International programs, in co-operation with industries and research groups. He is a member of the expert group responsible for issuing the European standard EN12309;2013 for evaluating the seasonal performance of gas-driven heat pumps. He has been participating in the IEA-Task 34 for TDHPs Dr.-Eng. Lucio Bonaccorsi graduated with an M.D.in Chemical Engineering from the University of Pisa, PhD in "Chemistry of Materials for Special Applications". He worked five years as process engineer for the UOP Molecular Sieves Spa, a partnership company of the UOP LLC group (1995-2000). M.D. "Six Sigma Process Improvement" on statistic methodologies for industrial experimentation (1997). In July 2000 he started working as Researcher Engineer in Material Science at the Faculty of Engineering of the University of Messina. He is "associated professor" at the CNR-ITAE institute. The scientific activity of Dr.-Ing. Bonaccorsi mainly concerns the synthesis and characterization of microporous materials with conventional and microwave methodologies. He is author of more than 50 printed papers. Dipl.-Eng. Stefanie Chmielewski (Stefanie Lohmöller) studied energy engineering and graduated from RWTH-Aachen University, Germany in 2006. Her diploma thesis concerned the investigation of the evaporator size as well as the zeolite mixture and their influence on the potential of a two modular adsorption heat pump working with the thermal wave concept. Since 2006 she is working at the Viessmann Werke in Allendorf/Eder, Germany as a development engineer and since 2009 as a team leader for the development of a zeolite-water adsorption heat pump module. She contributed on several papers and patents in the field of TDHPs and co-authored a book (VDI project final report) on the development of a gas d
