Deep geothermal energy is seen as key to the energy transition, but its implementation is challenging and, in the case of hydrothermal systems, often involves a high risk of failing to find a suitable site. The Haute-Sorne pilot project demonstrates how these challenges might be overcome – with impressive results from deep drilling, hydraulic stimulation and state-of-the-art monitoring.

Based on an article by Claus Hecking in Der Spiegel The article highlights a technological irony: whilst the major tech corporations in Silicon Valley (Google, Meta, Amazon) are desperately searching for clean, large-scale energy sources for their AI data centres, they are relying on a technology that was largely co-developed in Germany – but which has almost disappeared into obscurity there, both politically and socially.

The pilot geothermal power plant project in Glovelier, in the municipality of Haute-Sorne (Jura), began drilling on 21 May 2024, following a decade of political and legal deadlocks and local opposition. The Swiss start-up Geo-Energie Suisse aims to generate CO2-free electricity from heat extracted from deep within the earth. For the Swiss start-up Geo-Energie Suisse AG, this project is a real make-or-break venture: failure would likely spell the end of deep geothermal research in Switzerland.
