Proceedings 2020 for room 3

Monday, 9th November

10 am - 12 pm CEST

Chair of the meeting: Thomas Jahrfeld, SWM Services GmbH und Michael Meinecke, SWM Services GmbH

Summary of the meeting:

A lot of research and development work was done in the run-up to and in the course of the implementation of the Schäftlarnstrasse geothermal project. The workshop shows numerous results and further questions.

The cooperation between the implementation project and the R&D projects is a building block for success. When creating the deep boreholes, data was consistently collected and this data was used from borehole to borehole. The workshop shows numerous results and further questions. It gives an overview of the project results and is intended to give a brief outline of the synergy of applied research and development in a geothermal project.
