Daniel Favrat

Daniel Favrat got his Master degree in Mechanical Engineering from EPFL in 1972 and his PhD also from EPFL. He then spent 12 years in industrial research laboratories in Canada (Esso Canada) and Switzerland (CERAC: Centre Européen de Recherche Atlas Copco). From 1988 to 2013, he was full professor and director of the Industrial Energy Systems Laboratory (LENI) at EPFL. During that period he was successively director of the Institute of Energy and director of the Institute of Mechanical Engineering. From August 2013 he works at EPFL Energy Center first as director ad interim and now as director technologies. His research fields include systemic analyses accounting for energy, environment and economics (so-called environomic optimisation) and advanced conversion systems for a more rational use of energy (heat pumps &ORC, engines, fuel cells, power plants, etc). He is a member of the Swiss Academy of Engineering Sciences and of the National Academy of Technology in France. He has also an active participation in the World Federation of Engineering Organizations (WFEO) as a member of the executive committee and vice-chair of the energy committee. He is associate editor of the journal "Energy" and of International Journal of thermodynamics. He is the author of several books on thermodynamics and energy systems analysis. He is also affiliate professor at the Royal Institute of Technology (KTH) in Stockholm.

François Maréchal

Ph D. in engineering Chemical process engineer Researcher and lecturer in the field of computer aided process and energy systems engineering. Lecturer in the mechanical engineering, electrical engineering and environmental sciences engineering in EPFL. I'm responsible for the Minor in Energy of EPFL and I'm involved in 3 projects of the Competence Center in Energy and Mobility (2nd generation biofuel, Wood SOFC, and gas turbine development with CO2 mitigation) in which i'm contributing to the energy conversion system design and optimisation. Short summary of my scientific carrer After a graduation in chemical engineering from the University of Liège, I have obtained a Ph. D. from the University of Liège in the LASSC laboratory of Prof. Kalitventzeff (former president of the European working party on computer aided process engineering). This laboratory was one of the pioneering laboratory in the field of Computer Aided Process Engineering. In the group of Professor Kalitventzeff, I have worked on the development and the applications of data reconciliation, process modelling and optimisation techniques in the chemical process industry, my experience ranges from nuclear power stations to chemical plants. In the LASSC, I have been responsible from the developments in the field of rational use of energy in the industry. My first research topic has been the methodological development of process integration techniques, combining the use of pinch based methods and of mathematical programming: e.g. for the design of multiperiod heat exchanger networks or Mixed integer non linear programming techniques for the optimal management of utility systems. Fronted with applications in the industry, my work then mainly concentrated on the optimal integration of utility systems considering not only the energy requirements but the cost of the energy requirements and the energy conversion systems. I developed methods for analysing and integrating the utility system, the steam networks, combustion (including waste fuel), gas turbines or other advanced energy conversion systems (cogeneration, refrigeration and heat). The techniques applied uses operation research tools like mixed integer linear programming and exergy analysis. In order to evaluate the results of the utility integration, a new graphical method for representing the integration of the utility systems has been developed. By the use of MILP techniques, the method developed for the utility integration has been extended to handled site scale problems, to incorporate environmental constraints and reduce the water usage. This method (the Effect Modelling and Optimisation method) has been successfully applied to the chemical plants industry, the pulp and paper industry and the power plant. Instead of focusing on academic problems, I mainly developed my research based on industrial applications that lead to valuable and applicable patented results. Recently the methods developed have been extended to realise the thermoeconomic optimisation of integrated systems like fuel cells. My present R&D work concerns the application of multi-objective optimisation strategies in the design of processes and integrated energy conversion systems. Since 2001, Im working in the Industrial Energy Systems Laboratory (LENI) of Ecole Polytechnique fédérale de Lausanne (EPFL) where Im leading the R&D activities in the field of Computer Aided Analysis and Design of Industrial Energy Systems with a major focus on sustainable energy conversion system development using thermo-economic optimisation methodologies. A part from the application and the development of process integration techniques, that remains my major field of expertise, the applications concern : Rational use of water and energy in Industrial processes and industrial production sites : projects with NESTLE, EDF, VEOLIA and Borregaard (pulp and paper).Energy conversion and process design : biofuels from waste biomass (with GASNAT, EGO and PSI), water dessalination and waste water treatment plant (VEOLIA), power plant design (ALSTOM), Energy conversion from geothermal sources (BFE). Integrated energy systems in urban areas : together with SCANE and SIG (GE) and IEA annexe 42 for micro-cogeneration systems. I as well contributed to the definition of the 2000 Watt society and to studies concerning the emergence of green technologies on the market in the frame of the Alliance for Global Sustainability.

John R. Thome is Professor of Heat and Mass Transfer at the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland since 1998, where his primary interests of research are two-phase flow and heat transfer, covering both macro-scale and micro-scale heat transfer and enhanced heat transfer. He directs the Laboratory of Heat and Mass Transfer (LTCM) at the EPFL with a research staff of about 18-20 and is also Director of the Doctoral School in Energy. He received his Ph.D. at Oxford University, England in 1978. He is the author of four books: Enhanced Boiling Heat Transfer (1990), Convective Boiling and Condensation, 3rd Edition (1994), Wolverine Engineering Databook III (2004) and Nucleate Boiling on Micro-Structured Surfaces (2008). He received the ASME Heat Transfer Division's Best Paper Award in 1998 for a 3-part paper on two-phase flow and flow boiling heat transfer published in the Journal of Heat Transfer. He has received the J&E Hall Gold Medal from the U.K. Institute of Refrigeration in February, 2008 for his extensive research contributions on refrigeration heat transfer and more recently the 2010 ASME Heat Transfer Memorial Award. He has published widely on the fundamental aspects of microscale and macroscale two-phase flow and heat transfer and on enhanced boiling and condensation heat transfer.
