Geothermal Energy: Power Generation and Applications

This lecture covers geothermal energy systems, including dry steam, flash, and binary cycle power plants. It explores the utilization of low and high-temperature sources, such as Stirling cycles and ORC for electricity generation. The efficiency evolution and perspectives of geothermal power plants are discussed, along with concentrated solar power applications. The lecture also delves into refrigeration and heat pump systems, emphasizing vapor-compression and gas refrigeration cycles. Various working fluids and their critical parameters for ORC systems are analyzed, along with biomass applications. The instructor presents examples of geothermal power plants worldwide and the potential of geothermal energy for electricity production and direct heat use.
