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.
Jacques LévyJacques Lévy (1952-) is a geographer and an urbanist, full professor at the Swiss Federal Institute of Technology, Lausanne (EPFL). He is the director of Chôros Laboratory and the director of the Architecture and Sciences of the City doctoral programme.
Topics
His major concerns are social theory of space, urbanity, globalisation, cartography, and the epistemology of social sciences. He has completed numerous research projects, including theoretical reflections, field studies on metropolises worldwide, and practical urban and territorial projects. He is working on the introduction of non-verbal, namely audio-visual languages, in all dimensions of academic research. He has been the director of a scientific film, Urbanity/ies (2013)
Positions and Activities
Formerly, he has been researcher at the French CNRS, then professor at the Paris Institut détudes politique (Sciences Po, F) and at Rheims University (F). He has been invited professor in various universities: UCLA, NYU, USP (São Paulo), LOrientale (Naples), Macquarie (Sydney), and the Reclus Chair in Mexico City. He has been a fellow of the Wissenschaftskolleg zu Berlin (2003-2004). He has been invited as a keynote speaker in many congresses and conferences throughout the World.
He is the co-editor of EspacesTemps.net, a bilingual free-access journal of social sciences. He is the co-director of Lespace en société book series at PPUR/EPFL Press publisher. He is the scientific adviser of Pouvoirs Locaux journal. He is member of the international Grand Prix de lUrbanisme (Paris). He has numerous collaborations with newspapers and radio channels in France and Switzerland.
