What is Eavor-Loop (Geretsried)?

The Eavor-Loop is a closed-loop geothermal system that circulates a working fluid through a sealed network of wellbores drilled deep underground, absorbing heat by conduction from the surrounding rock without extracting any water or steam from the earth. The fluid rises to the surface through a gravity-driven thermosiphon effect, delivering heat for power generation or direct heating without the need for a naturally permeable reservoir.
