Master’s Thesis within the Sustainable Energy Systems programme

With the rise of environmental awareness and increased electricity prices, low temperature electricity production cycles are getting more and more into focus. These include applications that produce electricity from industrial waste heat, which otherwise would have been released to the environment. They can also be used for medium enthalpy geothermal heat sources from 125 to 225 °C. The purpose of this Master Thesis is to identify and compare different technologies to produce low temperature electricity, according to their profitability and efficiency. Moreover, this Thesis focuses on investigating electricity cycles for further use in geothermal power plant applications. Finally the specific case of Geotermica1 is studied. Low temperature electricity production cycles have been identified during a literatur
