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... goto

NRG2019: Energy Systems: managing the transition to renewables


Life Cycle Assessment in energy systems

This course will introduce students to the Life Cycle Assessment (LCA) as a holistic approach to evaluate, among others, energy conversion technologies throughout their entire value chain, and across multiple environmental problems beyond climate change. goto

Global issues: energy B

This course offers an overview of global techno-economic and social challenges related to energy transitions to a low carbon economy, and will discuss the prospects and barriers to the implementation of a future sustainable energy system. goto

Energy conversion and renewable energy

The goal of the lecture is to present the principles of the energy conversion for conventional and renewable energy resources and to explain the most important parameters that define the energy conversion efficiency, resources implications and economics o... goto

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 a... goto

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... goto

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. goto
