Potential for heat extraction and storage in Danish sedimentary basins – insights from numerical modelling

PhD defence, Monday 27 September 2021, Márton Major

Márton Major

During his PhD studies, Marton Major researched different aspects of geothermal heat generation in typical Danish sedimentary basin environments. Deep sedimentary reservoirs hold enormous amounts of heat energy, which can be utilized through extraction of warm water from deep boreholes. Marton Major studied how geological variability effects the thermal production profile of geothermal plants and the effectiveness of thermal storage in deep sedimentary reservoirs.

The results from this research contribute to the understanding of heat and fluid flow under heterogeneous conditions and compares different ways of including heterogeneity in computer models. Additionally, the storage potential of deep reservoirs is quantified.

The PhD study was completed at Department of Geoscience, Faculty of Natural Sciences, Aarhus University. This summary was prepared by the PhD student.
