The brief
- Eavor-Loop: sealed radiator design with fluid descending one wellbore and returning heated through another, no reservoir contact.
- Eavor-Lite near Rocky Mountain House, Alberta (2019–2024) proved circulation and heat extraction.
- Geretsried, Germany: four-loop facility began electricity supply December 2025; encountered clogging mid-2026.
Technical approach
No reservoir drilling, no fracking
Proprietary fluid circulates down one wellbore and back up through another. Heat transfers via pipe walls without contact to water or steam reservoirs.
No seismic, water depletion, brine or aquifer risk
Avoids fracturing (no induced seismic), minimal water (no extraction), no brine contamination.
Multiple loops, parallel deployment
Multiple loops scale output without more reservoir capacity; repeatable at any location.
