Biomass conversion

The learning outcomes are to get to know the biomass ressources and its characteristics; study of biomass conversion pathways and study of process flow-sheets; establish the flow diagram of an industrial process with biomass as feedstock and calculate the corresponding mass and energy balances; etc

NRG2019: Energy Systems: managing the transition to renewables

This Summer School will try to bring to together these very disparate topics including energy policy, modeling and technologies in one coherent single event and give the participants a unique perspective on the opportunities and challenges of the coming energy transition.

Energy conversion and renewable energy

This course presents an overview of (i) the main principles of energy conversion for conventional (fossil and nuclear) and renewable energy resources and of (ii) the most important parameters that define the efficiency, resource use, costs and impacts of the associated technologies.

Advanced energetics

Methods for the rational use and conversion of energy in industrial processes : how to analyse the energy usage, calculate the heat recovery by pinch analysis, define heat exchanger network, integrate heat pumps and cogeneration units and realise exergy analysis of energy conversion systems.

Modelling and optimization of energy systems

The goal of the lecture is to present and apply techniques for the modelling and the thermo-economic optimisation of industrial process and energy systems. The lecture covers the problem statement, the solving methods for the simulation and the single and multi-objective optimisation problems.

Modelling, optimisation, design and analysis of integrated energy systems

The student will learn advanced concepts in the field of process integration, process modeling and optimization for the design of integrated energy systems: Life cycle energy analysis.
