Numerical modelling of shallow geothermal energy exploration process — •Haibing Shao — Helmholtz Centre for Environmental Research - UFZ, Permoserstr. 15, 04318 Leipzig, Germany

In the context of energy transition in German and all over the world, the extraction of shallow geothermal energy by Borehole Heat Exchangers (BHEs) is considered to be a technology with low carbon emission for building heating and cooling purposes. This talk will introduce the numerical simulation approach that has been applied to study the coupled physical processes caused by geothermal extraction from the shallow subsurface. Results from recent studies will be presented in order to answer following questions.

1) What are the influencing factors for BHE efficiency?

2) How much energy can be sustainably extracted from the shallow subsurface?

3) What will be the potential environmental impacts, e.g. on downstream groundwater temperatures?
