15.07.2026 PhD Position – Prospective Environmental and Economic Assessment of a Data Center for the Einstein Telescope in Jülich At the Institute of Climate and Energy Systems – Jülich Systems Analysis (ICE-2), we investigate how sustainable, climate-neutral energy systems can be designed. To this end, the Department of Circular Economy researches and develops innovative methods and tools for a holistic assessment of upcoming technologies and circular economy concepts. To map these systematically, methods for (prospective) Life Cycle Sustainability Assessments (LCSA) are continuously being refined. In addition to minimizing environmental impacts and waste streams while maximizing resource efficiency, we analyze societal impacts and economic implications. Start Date: To the next possible…
