General information on the SM

The simplified models (https://www.geoenvi.eu/wp-content/uploads/2021/02/D3.4-Simplified-parameterized-models.pdf) were developed as one of the outcomes of the European project GEOENVI [Grant agreement n°818242 -- 2018-2021]. 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.

The simplified models are based on equations with a small number of variable parameters and provide first environmental assessments of geothermal installations belonging to any of the four categories described, whenever the resources are lacking to conduct full life cycle assessments (LCAs). The generation of the simplified models for each of the four categories of geothermal installations relied on a five-step protocol (https://www.geoenvi.eu/publications/elaboration-of-a-general-protocol-to-generate-simplified-models-for-geothermal-installations/) including:

(i) the definition of the scope of the study
(ii) the modelling and validation of the reference LCA model
(iii) the statistical process to identify the key input variable parameters for each impact category
(iv) the generation and validation of the simplified models, and (v) the description of the models’ applicability domain.

The reference LCA model was developed based on one representative geothermal installation per category and followed whenever possible the LCA guidelines developed within GEOENVI (https://www.geoenvi.eu/publications/lca-guidelines-for-geothermal-installations/). Adaptations were necessary to ensure that the developed reference LCA model was not too specific for the representative installation and thus general enough to represent all possible installations within that category. Seven simplified models per category of geothermal installation were developed, describing impacts on climate change, minerals and metals resource depletion, fossil resource depletion, human carcinogenic effects, human non-carcinogenic effects, freshwater ecotoxicity, and freshwater and terrestrial acidification. Each model relied on two to six variable parameters specific to the geothermal installation and explaining around 75% or more of the variance observed per impact category. In addition, the simplified models for the EGS for heat generation includes electricity shares as inputs to consider different types of electricity mix used to power the pumps during the plant’s operation phase. It appears that the influencing variable parameters vary depending on the impact category and the geothermal installation category. Only the most influencing variable parameters were kept per simplified model, as explained in more details in the description of the protocol.

The simplified models presented here are first estimates of the environmental impacts of a geothermal installation and do not replace a full Life Cycle Assessment. While a simplified model is a good representation of a specific type of geothermal installation, its accuracy in estimating the environmental impacts does not fully match the one of a full LCA. Furthermore, the use of the simplified models is strictly limited to the defined applicability domain. Carefully choosing among the different types of installations available is therefore essential to ensure the relevance of the estimated impacts. Whenever an installation falls partly within the defined parameter ranges and/or the specified applicability domain, the user might want to apply all simplified models and compare their outcomes. We suggest that if the results per impact category for each installation type vary by less than 10%, the estimated values might be considered an acceptable first rough estimate of the environmental impacts of the considered installation. Otherwise, we advise against the use of the simplified models and recommend the development of a new simplified model for the specific installation type. Overall, we advise against applying a simplified model to an installation whose characteristics do not match the defined parameter ranges or the specified applicability domain at all.

Terminology

Applicability range

The range of values for each parameter which the reference LCA model and simplified models can be applied.

CHP

Combined Heat and Power geothermal plant with low direct emissions.

EGS

Enhanced geothermal system technology, for heat generation with very low direct emissions.

Flash

Type of geothermal power plants whose primary scope are the production of electricity where steam drives generator turbines. Such plants produce also heat which is delivered through a heat transfer network for industrial uses.

HeatORC

A heat production plant including a demonstration ORC producing electricity for self-consumption with very low emissions.

Impact category

In the LCA impact assessment (LCIA) potential environmental impacts are calculated based on the inventory results of the life cycle. Inputs and outputs are multiplied by a specific characterisation factors and all the contributions to different impact categories are summed up to obtain a single impact value for each considered category.

Monte Carlo simulation

Ensemble of statistical techniques generating random samples of parameters from their probability distribution functions to estimate the uncertainty of the model's outcome which is defined by these parameters.
