Figure 1

EGS reference model for EGS power plants (based on an explicit LCI). Data regarding the amount of materials and processes involved over the life cycle of the EGS power plants (black boxes) are scaled with the nine parameters of the model (blue boxes). Information concerning background processes are retrieved from ecoinvent v2.2 (red box). The specific LCI obtained for each part of the model is indicated by the orange boxes. GHG emissions (green boxes) are calculated through the IPCC characterization factors (violet box). The nine parameters also allow for the calculation of the electricity produced by the EGS power plant over its lifetime.
