Profile & expertise

TU Darmstadt is a public research institution. The field of Geothermal Science and Technology has scientific and engineering roots and combines basic geoscientific knowledge with the requirements of practical industry applications. The research focus of the Department of Geothermal Science and Technology is the determination of petrophysical rock properties, numerical modelling in the field of geothermal energy, the assessment of geothermal reservoirs and resources, fluid-formation-interactions, thermal and mineral waters, development of measurement instrumentation and the integration of geothermal systems into networks of other (renewable) energy systems. 

Role in the Project

TU Darmstadt will carry out the development of integrated thermo-hydraulic (TH) 3D geothermal models based on petrophysical and hydraulic rock properties from existing data compilations (Bär et al. 2015) and on data measured on outcrop analogue and core samples from test sites. This includes:

 TU Darmstadt will conduct petrophysical analysis on cores if available and compare lab scale properties with properties derived from borehole geophysics and will conduct petrophysical preparation and will provide the parameters for coupled THMC modeling.

TuDa is also involved to aid with the determination of the site specific optimal geothermal energy usage and to develop best practice guidelines for industry”

Dr. Kristian Bär, Assessment and 3D-modelling of geothermal resources and potentials, laboratory petrophysics, outcrop analogue studies and data base development, statistical data analysis and stochastic integration of thermophysical and hydraulic data in 3D structural models of the subsurface to predict temperature distribution, reservoir properties as a basis for the assessment of the geothermal potential of different reservoir types. 


Prof. Dr. Ingo Sass holds the Chair of Applied Geothermal Science and Technology at TU Darmstadt. His main research topics are Geothermics, Hydrogeology and Drilling Technology. Bibliography: 40 scientific papers, 3 monographies, 1 book, 102 proceeding papers, 46 conference proceedings. He was supervisor/co-supervisor of 10/21 successfully defended PhD theses and more than 70 Master degree or Diploma degree thesis.


Aysegul Turan is a PhD candidate in the Geothermal Science and Technology Working Group at the Institute of Applied Geoscience, Technical University of Darmstadt. She received her master degree in the Sustainable Environment and Energy Systems Master Program at Middle East Technical University (METU)-Northern Cyprus Campus in 2016. Her master’s study focused on feasibility of an enhanced geothermal system application in Dikili-İzmir region (Western Anatolia, Turkey). She earned her bachelor’s degree from METU, Ankara/Turkey in 2010 in Geological Engineering. After receiving her bachelor’s degree, she joined the Petroleum and Natural Gas Engineering Department and worked four years as Teaching Assistant. Before joining TUDa, she has worked in different companies from the Turkish geothermal private sector for two years. That enabled her a manifold research process. Through her graduate studies, she published three conference proceedings and received a grant of 1300 € to present her research findings at the World Geothermal Congress in Melbourne 2015 and Geothermal Resources Council Annual Meeting in Sacramento 2016. She is a member of the Women in Geothermal (WinG) global network and has been actively representing WinG Turkey.

Rhadityo Arbarim (born 1990) is a PhD researcher in Institut für Angewandte Geowissenschaften, Fachgebiet Angewandte Geothermie, Technische Universität Darmstadt since January 2019. He achieved his bachelor degree in Institut Teknologi Bandung, Indonesia majoring in Petroleum Engineering from 2009 to 2013. He continued his career as a Production Engineer in Energi Mega Persada Malaca Strait in Indonesia. His responsibility involved supervision of wireline operation and hydraulic fracturing. He received his master degree in Applied Earth Science from Technische Universiteit Delft, Netherland in 2018. His thesis was a significant contribution to the development of Delft Advanced Reservoir Simulation (DARSim) and successfully presented in ECMOR XVI in Barcelona, September 2018 and SPE Reservoir Simulation Conference in Galveston, April 2019. His research interests involve numerical modelling of fluid flow in porous media and thermo-hydro-mechanical (THM) coupling in fractured media for the application of Enhanced Geothermal Systems.
