Assessing the Environmental Sustainability of Deep Geothermal Heat Plants

The energy sector is responsible for a large share of climate-damaging emissions. Regarding the decarbonization sector, deep geothermal considered to have high potential, particularly in area heat supply. In order gauge extent which use from can make positive contribution climate protection, systems should be appraised using an environmental sustainability assessment. Although electricity generation power plants has been evaluated many ways literature with respect its sustainability, no such evaluations pure conducted so far. close this research gap, study presents systematic approach that makes it possible apply suitable criteria across individual life stages based on life-cycle assessment (LCA) guidelines. To demonstrate effectiveness presented here, planned plant Upper Rhine Valley, Germany, serves as example. Based estimated parameters and predicted total yield, was determine, example, “energy returned invested” (EROI) plant, approximately 34, specific CO2 emissions, were 5.6 g/kWhth.
