Eavor-Lite Demonstration Facility by Eavor Technologies: status and timeline

Milestones

No announced next step

Drilling completedSep 2019Complete.
Facility commissioned and circulation provenDec 2019Complete.
Two years of continuous operation concluded2024Complete.

Physics limits

Heat transfer limited by pipe wall surfaceHeat flows through steel pipe walls. Output depends on wellbore surface area and rock temperature.

How it works

1 part

Closed-loop radiator

Sealed heat exchanger at depth

Cool fluid descends one wellbore, absorbs heat, ascends through second wellbore. Operates without pump.

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.
