Dear colleagues,

it is our pleasure to announce the following scientific presentation, taking place on Monday, 18. January, 2021 at 2.00 pm:

PD Dr. Simona Regenspurg:

Solutions for Geothermal Energy Exploitation- Risks and Benefits utilizing Deep Fluids

Geothermal energy exploitation requires the establishment of a thermal water loop connecting the underground heat source with the energy plant at the surface. Thereby, pressure and temperature of the fluids change resulting in shifts of the chemical equilibrium and various reactions occur. Many of those are unwanted such as mineral precipitation (scaling) or material destruction (corrosion). Their prediction, however, is difficult due to the complexity of fluid composition, the high pressures, temperatures, and salinities of those fluids, and the unknown reaction kinetics.

Measuring and understanding those processes on field and lab scale is the key to predict and control them during operation of geothermal plants. This presentation gives an overview of experiments combined with in-situ measurements to prevent the unwanted reactions. In addition, since some of the fluid components are considered as economically valuable (such as lithium), the methods can also be used to allow beneficial reactions, e.g. the extraction of the valuable elements from the solutions.

Everybody interested is cordially invited to join.

Access data will be provided separately after registration with Martina Pakos (pakos@gfz-potsdam.de) by 11. January, 2021.

On behalf of Prof. Scheck-Wenderoth, Director of Department 4,

Martina Pakos
