Dr. Greg Frank Naterer is the Dean of Engineering and Professor of Mechanical Engineering at Memorial University of Newfoundland, Canada. He has made significant contributions to mechanical engineering, specifically the fields of heat transfer, hydrogen production, energy systems, multiphase flows and entropy based design. He led an international hydrogen research consortium, involving eight collaborating institutions, five countries and six industrial partners, which developed the first large-scale copper-chlorine cycle of thermochemical water splitting for hydrogen production. Dr. Naterer is a Fellow of the Canadian Society for Mechanical Engineering (CSME), American Society of Mechanical Engineers (ASME) and Engineering Institute of Canada (EIC). Dr. Ibrahim Dincer is a full professor of Mechanical Engineering in the Faculty of Engineering and Applied Science at University of Ontario Institute of Technology. He is Vice President for Strategy in International Association for Hydrogen Energy (IAHE) and Vice-President for World Society of Sustainable Energy Technologies (WSSET). Renowned for his pioneering works in the area of sustainable energy technologies he has authored and co-authored many books, book chapters and refereed journal and conference papers. He has chaired many national and international conferences, symposia, workshops and technical meetings. He has delivered many keynote and invited lectures. He is an active member of various international scientific organizations and societies, and serves as editor-in-chief, associate editor, regional editor, and editorial board member on various prestigious international journals. He is a recipient of several research, teaching and service awards, including a Premier’s research excellence award in Ontario, Canada in 2004. He has made innovative contributions to the understanding and development ofsustainable energy technologies and their implementation, particularly through exergy. He has actively been working in the areas of hydrogen and fuel cell technologies, and his group has developed various novel technologies/methods/etc. Dr. Calin Zamfirescu is a Senior Research Engineer at the University of Ontario Institute of Technology. His research interests include: Modeling advanced energy systems and process engineering systems, Development of low capacity heat engine for waste heat recovery, Solar driven heat engines and advanced Rankine cycles, Exergy content of solar radiation, and Fuel cells (including SOFC-H+) and combined systems with hydrogen, methane and ammonia.
