The simplified models presented in this report were developed as one of the outcomes of the European project GEOENVI.
These simplified models estimate the environmental impacts of four different categories of geothermal installations, namely:
(1) enhanced geothermal systems (EGS) for heat generation with very low direct emissions
(2) geothermal flash power plant producing electricity and a limited amount of heat from a geothermal source with moderate to high content of NCGs, composed mostly of CO2
(3) combined Heat and Power (CHP) geothermal plant with low direct emissions
(4) a heat production plant including a demonstration ORC producing electricity for self-consumption with very low emissions.
This report is still a draft and has to be reviewed by the European Commission.
