“…On the other hand, extraction of subsurface geothermal resources might be accompanied by CO 2 and CH 4 direct emissions, emissions of metals, etc. The authors of [44] reviewed 30 studies on geothermal plants and revealed the influence of the geotechnical parameters of various drilling sites on the environment. The authors considered the following geological conditions: temperature of fluids, reservoir depth, and rock properties.…”

“…The SimaPro 9.00.49® software (Pre Consultants, 2011) is used. The widely used, on geothermal LCAs (Gkousis et al, 2022), CML developed impact assessment method (van Oers, 2015) is used for the GW, OD, AD and EP categories. For the POC and AC impacts the ILCD+2011 method (JRC, 2011) is used to calculate the results in the units suggested by the GEOENVI guidelines (Parisi et al, 2020).…”

“…Ten parameters, presented in Table 5, are varied in the GSA. They are selected based on the results of the LCA and the results presented in previous studies (Gkousis et al, 2022). The GSA is not performed for the AD and CEDren impacts because they are dominated by the building construction and the geofluid use respectively.…”

“…Geothermal energy, however, entails a critical concern in regard to the environmental impact, among others, associated with the construction, operation and end-of-life (EOL) [12,13] of a power plant. There are critical concerns with the high amount of noncondensable gases included in the geothermal fluid composition, which will later represent an environmental impact due to the emissions released to the atmosphere during GPP operation, apart from the problems that are created in the operation (corrosion, calcite deposition, etc.)…”
