Most important updates

Current obstacles

Rock fragment clogging in wellboresRock debris accumulated in completed loops. Cleaning could not fully clear two loops by May 2026.
Scaling four-loop operations with circulation balanceMaintain equal pressure and temperature distribution across multiple loops operating in parallel at extreme depth.

Physics limits

Heat transfer via pipe wallsHeat flows through steel without direct rock contact. Maximum output constrained by pipe surface area and rock temperature gradient.

How it works

2 parts

Four parallel closed loops

Modular depth radiators

Four independent U-tube circuits operate at 4.5 km depth. Each loop descends, absorbs heat from rock, and ascends independently.

Dual output

Heat and electricity

Hot fluid supplies district heating network directly; excess heat drives an organic Rankine cycle turbine for grid electricity.

About Eavor Technologies

The team behind Geretsried Commercial Facility

Eavor Technologies

Closed-loop geothermal, Eavor-Loop, no fracking

Eavor develops closed-loop geothermal without reservoir drilling, eliminating fracturing and seismic risk. Demonstrated in Alberta; commercial deployment in Germany began December 2025.

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.
