Subject fundamentals
The description, modelling, analysis of advanced energy systems based on the integration of power, thermo-chemical and electro-chemical processes for poly-generation purposes. Starting 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.
Some activities at the lab level (mainly on electrochemical and thermochemical systems applied to energy) will be developed along the course.
Expected learning outcomes
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.
Prerequisites / Assumed knowledge
Preliminary knowledge acquired in the courses of Thermodynamics and Heat Transfer, Chemical Plants, Material Science. Lectures given in English.

Gasification
Supercritical water gasification
Biogas
Principles of chemical looping (example: fuel decarbonization)

HYDROGEN TECHNOLOGIES
Physical and chemical properties of H2
Reforming of hydrocarbons
Production from renewables
Storage of hydrogen (liquid, metal hydride)

CHEMICAL STORAGE FOR THE PRODUCTION OF SYNTHETIC FUELS
RES-storage and synthetic fuels
Processes for CO2 recovery
CCS processes
Principles of power-to-gas (P2G) processes
Production of synthetic methane
Principles of power-to-liquid (P2L) processes

EXAMPLES OF COMPLEX POLY-GENERATION SYSTEMS
WWTU plant with MCFC CHP system and hydrogen recovery
WWTU plant with SOFC system and CO2 recovery and carbon fixation in algae
IGCC integrated with SOFC systems and CCS
Delivery modes
A project (home assignment) will be developed during the LAIB lectures using the ASPEN+ tool.
The Topic varies every year (as an example: feasibility study of a biogas fed SOFC system)

In the labs, experimental tests will be developed on single cells and stack PEMFC (3 h) and on single cells and stack SOFC (3 h), on high pressure electrolysis and high temperature electrolysis (1.5 h), on Li-ion batteries (1.5 h), on thermo-chemical systems (3.0 h in SMAT).
