PhD Position - Techno-economic assessment of geothermal plants with material co-production in e[...]

Do you want to contribute to securing the critical raw materials needed to enable the European energy transition while working with powerful energy system models within an international team of researchers? Then become part of our team at the Institute of Climate and Energy Systems - Jülich Systems Analysis and contribute to our research with your PhD thesis. Here at our institute, we investigate what a sustainable energy system could look like, providing meaningful analyses and scenarios for policymakers. Within the Marie Skłodowska-Curie project MiningBrines, we use our skillset to help develop a sustainable brine mining whole strategy that extracts and valorises renewable energy, energetic gases, and critical raw materials from geothermal brines across European geothermal wells.

Your Job

Critical Raw Materials (CRM) are those raw materials with unique properties that are economically and strategically important for the European economy and energy transition towards a carbon neutral future. Geothermal wells are located all over Europe and contain various minerals such as Lithium or Boron and energetic gases such as hydrogen and methane. Currently these geothermal wells are mostly used for their heat-energy properties. The MiningBrines project funded by the EU Horizon programme aims to develop a strategy to extract CRM and other materials from geothermal brines while at the same time continuing to supply renewable energy. Your goal as one of 19 international PhD candidates within the project is to evaluate the economic viability of geothermal plants that produce power, heat, and critical materials by comparing them to other energy sources and extraction methods, while considering future demand, price trends, and incorporating data on resource productivity, innovative extraction methods, and social acceptance. For this you will work together with project partners to retrieve real‑world techno‑economic data as a foundation for integrating geothermal plants into European energy system models based on the institute’s own open‑source FINE framework

Your tasks in detail

• Implement geothermal plants with material co‑production in energy system optimisation models including reservoir productivity predictions, novel surface processes for CRM extraction, CO₂ reinjection, and reconversion of decommissioned oil wells.
• Economic evaluation of traditional material extraction methods and projection of future demand and price trends of critical materials.
• Identification of specific conditions under which geothermal plants are economically viable and cost competitive in energy systems.
• Further assessment of the strategic role of geothermal plants with material co‑production in future European energy systems.

Your Profile

• Very good results in your Master’s degree in the field of energy technologies, engineering, environmental sciences, renewable energies, industrial engineering, materials and geosciences or a related field.
• Great interest in energy technology, energy economics and policy issues.
• Experience in programming with Python or a comparable programming language.
• Experience in energy system modelling is an advantage.
• Highly motivated and able to work independently and in an analytical manner.
• Reliable and conscientious working style with a high level of self‑organisation and time‑management skills.
• Fluent command of written and spoken English is required (at least B2 level according to the CEFR: German language skills are advantageous.
• According to the mobility regulations of Marie‑Sklodowska‑Curie actions you must not have lived or carried out your main activity (work, studies, etc.) in Germany for more than 12 months in the last three years.

Application Documents

Besides a CV and a letter of application, please include the following documents:

• A 1‑page critical summary of an article of your choice.
• The name of two contact persons (former teachers or supervisors, who are asked to send a support letter).
• Your academic credentials.

Our Offer

Being part of the Marie‑Sklodowska‑Curie doctoral network MiningBrines we are offering ideal conditions for you to complete your doctoral degree:

• INTERDISCIPLINARY TRAINING: An interdisciplinary training program, including academic research, international mobility, and industrial immersion.
• INTERNATIONAL COLLABORATION: Collaboration with 32 international project partners and 18 other PhD candidates.
• SECONDMENTS ABROAD: 4 secondments to industrial and academic project partners in France, Croatia, Turkey and Hamburg (Germany).
• NETWORKING & EXCHANGE: Participation in national and international conferences and workshops.

Additionally, the Institute of Climate and Energy Systems – Jülich Systems Analysis offers to all its PhD students:

• TEAM & ENVIRONMENT: You will work in a motivated team with an international and interdisciplinary focus – at one of the largest research institutions in Europe.
