Badenova and Herrenknecht have finalised a 50-50 joint venture to develop a deep geothermal heating project near Freiburg, Germany, with €60m investment to supply 2000 households. The project has received regulatory approval and drilling is scheduled to begin in H2 2027 at 3200 metres depth.

◆ ◆ The Wire takeaway
Deep geothermal drilling at scale is now a proven product-market fit in Europe: a tunnelling company and a utility just bet €60m on it together, with regulatory approval already in hand. If you sell drilling, pumping, or heat-distribution equipment into German utilities, you now know your customer is moving from evaluation to procurement.
