This course focuses on conventional and renewable energy technologies within the framework of the European net-zero carbon target for 2050. The students will be progressively introduced to the primary energy sources and their basic transformation processes, including Fossil Fuels (Oil, Gas, Coal) and their uses in Internal Combustion Engines and Thermal Power Stations, Solar and Wind Energy Systems, Thermal and Photovoltaic Solar Systems, and Hydroelectric plants. The course will also cover the Environmental and Climate Impact of Energy-related Processes, including global warming from CO2 production, transitional mitigation strategies, such as CCS, and the European Energy Transition Strategies and Policies. The technological bottlenecks related to energy storage from renewables, the transfer of energy in the form of synthetic fuels (methane, hydrogen) and their integration in the power grid will also be discussed.
