Objectives

The course aims to provide key knowledge on modern high performance energy conversion systems for power generation and industrial applications.
The course is divided into two main parts: Advanced energy systems and Technologies for energy efficiency.
In the first part, the course provides an insight into the latest industrial energy conversion technologies based on the use of fossil fuels, with particular reference to combined cycle power plants, cogeneration systems and integrated systems with CCS processes for production of high-grade fuels and hydrogen in particular.
In the second part, the course provides some basic knowledge on modern energy storage technologies, essential for the effective and efficient management of non-programmable renewable sources, on heat exchange equipment and on process integration through heat exchanger networks.
The educational objectives and expected results are the following:
1. To acquire the specialized knowledge and the ability to interpret the structural and functional characteristics of the gas-steam combined cycles, cogeneration plants and industrial processes and systems for the rational use of energy, principles of operation, performance characteristics, environmental implications, technological evolution, also in connection with changes in legislation and structure of supply and demand of energy.
2.
