The first phase of testing at DeutscheErdwärme's Graben-Neudorf geothermal project near Karlsruhe, Germany, has just been completed. The results were better than expected, with temperatures of over 200 degrees Celsius measured at a depth of 4,000 meters. This makes Graben-Neudorf-1 the hottest borehole in Germany at this depth.

We initially reported the start of drilling at the Graben-Neudorf site in mid-2022, and there was an update on the well in a webinar in late 2022.

The data will be evaluated in the coming months, but this is a positive development for the project, which initially targeted reservoirs with naturally high permeability and temperatures of around 160 degrees Celsius. A combined geothermal heating and power plant is planned to be developed in Graben-Neudorf.

A second test phase is planned, but the higher than expected temperatures also place higher demands on the test equipment. Therefore, the technical requirements will need to be adjusted before the second test phase can begin.

Hot water extraction has just been reported at the Graben-Neudorf site following the completion of a technical inspection of the geothermal borehole. The drilling equipment at this location will now be dismantled pending a decision at the end of the year on whether to drill a second test well.

The development project in Graben-Neudorf is the most advanced project of the German geothermal company. In addition to Graben-Neudorf, the company is also developing geothermal projects in Dettenheim, Waghäusel and Karlsruhe-Neureut. All of these projects are in relatively early stages of development, with the Waghäusel project making the news a few weeks ago for being submitted to a referendum.
