Sektion 4.8: Geoenergie

Research fields:

Geothermal (Urban) Heat Supply GE

middle deep reservoirs (< 60°C)
deep reservoirs (> 60°C)

  • Innercity exploration, e.g. Berlin, Hamburg
  • Characterisation of the reservoirs and their cap rocks
  • Innercity drilling
  • Special concept to access the reservoir (stimulation)
  • Integration into energy supply systems

Thermal Storage TS

Underground Warmth and Cold Storage in Cities

  • Innercity exploration, e.g. Berlin, Hamburg
  • Protection of drinking water, well integrity, monitoring
  • Integration in energy supply systems

Geological Storage GS

Carbon Capture Storage and Utilization (CCS/U)
Hydrogen storage as key for future energy systems

  • Exploration close to utilisation, e.g. huge windfarms and electrolyse plants
  • Reactions of injected fluid (e.g. H2) with formation fluid und -rock and interaction with gas components (CO2, O2) and organic rock components (e.g. coal, oil, gas)
  • Integrity of wells, storage space, and cap rocks (steel, porosity, permeability)

Working groups:

Development of concepts for underground storage of fluids

Evaluation of coupled processes on the reservoir scale by laboratory experiments and numerical simulation

Advanced Reservoir Engineering Concepts (ARES) Nachwuchsgruppenleiter: Prof. Dr. Hannes Hofmann

Development and validation of advanced reservoir engineering concepts with focus on Enhanced Geothermal Systems (EGS)
