The description, modelling, analysis of advanced energy systems based on the integration of power, thermo-chemical and electro-chemical processes for poly-generation purposes. Staring from the fundamentals of chemical thermodynamics and electrochemistry applied to energy systems, the course develops topics related to electrochemical systems (fuel cells, electrolyzers, flow batteries), thermo-chemical systems (gasification, production of biogas, chemical looping systems), concepts of chemical storage for the production of synthetic fuels (CO2 recovery, power-to-gas, power-to-liquid processes) and complete this with the analysis of some examples of complex poly-generation systems.

Applications of fundamentals of chemical thermodynamics and electrochemistry to energy systems.
Understanding and design of complex energy systems based on thermo-chemical and electro-chemical processes and technologies.
Understanding and design of poly-generation systems.

Preliminary knowledge acquired in the courses of Thermodynamics and Heat Transfer, Chemical Plants, Material Science. Lectures given in English.
