Abstract


<p>In regions with favourable subsurface condition, geothermal resources provide a significant contribution to the reduction of man-made CO<sub>2</sub> emissions. Its economic utilization often requires reservoir engineering that bears the risk of a number of environmental challenges such as induced seismicity, groundwater pollution or radioactive scaling.</p><p>In order to develop a socially feasible geothermal utilization concept in the Upper Rhine Graben close to the city of Karlsruhe we designed a research approach in which interdisciplinary (between natural and social sciences) knowledge production is combined with transdisciplinary knowledge production. This means that besides the collaboration of scientists of various disciplines, stakeholder and citizens s from surrounding communities get the possibility to take part in the project through workshops and interviews. The results of those transdisciplinary interactions will be integrated through translation into technical parameters in the technical design of a geothermal utilization concept. For the development of utilization scenarios, technical criteria were adopted into technical parameter ranges. Furthermore, socio-ecological criteria such as &#8220;no induced seismicity&#8221; are translated into technical parameters by an experience-based approach. The resulting scenarios are substantiated by numerical models that address the energy outcome. They will be reflected in a second stakeholder workshop. Finally, recommendations for a geothermal heat utilisation concept will be formulated.</p>
