implementation and efficiency of enhanced geothermal systems (EGS) using CO2 as a working fluid (CO2-EGS).
This technology has attracted much interest of the scientific community in the last two decades due to the additional
benefit of CO2 geological storage that is occurring during the power generation process. The purpose of this
technology is to mitigate climate change by producing clean geothermal energy and simultaneously reduce carbon
dioxide emissions to the atmosphere coming from the combustion of fossil fuels. Within the paper, the scope of the
EnerGizerS project is indicated. Moreover, the preliminary results of case study locations for the CO2-EGS in both
Poland and Norway are presented.
