LCA and Exergo-Environmental Evaluation of a Combined Heat and Power Double-Flash Geothermal Power Plant

This study deals with the life cycle assessment (LCA) and an exergo-environmental analysis (EEvA) of geothermal Power Plant Hellisheiði (Iceland), a combined heat power double flash plant, installed 303.3 MW for electricity 133 hot water. LCA approach is used to evaluate analyse environmental performance at plant global level. A more in-depth developed, components level, through EEvA. The employs existing published data realignment inventory latest resource compares impacts three methods (ILCD 2011 Midpoint, ReCiPe 2016 Midpoint-Endpoint, CML-IA Baseline) two different scenarios. In scenario 1, any emission abatement system considered. 2, re-injection CO2 H2S accounted for. identifies some major spots impacts, like acidification, particulate matter formation, ecosystem, human toxicity, mainly caused by specific sources. Finally, allows indicating wells as significant contributors impact rate associated construction, Operation & Maintenance, end stages HP condenser component highest cost rate.
