Short summary

A workshop on the the scientific value and use of a 4500 m deep borehole on the campus of TU Delft in the Netherlands was held in June 2024. The borehole will serve as an observation infrastructure for processes in the underground related to human activities, such as exploitation of energy resources like geothermal energy or storage of heat or gas. The location is of great interest for this purpose as there are already two deep geothermal wells and shallow wells for heat storage.
