DEEPEGS – Deployment of deep enhanced geothermal systems for sustainable energy business

2016-2020
Partners: HS Orka (leader), with the participation of ÍSOR, Landsvirkjun and the geothermal research group GEORG from Iceland, BRGM (France), Fonroche Geothermie (France), Statoil (Norway), Herrenknecht Vertical (Germany), ENEL Green Power (Italy) and Karlsruhe Institute of Technology (Germany).

Coordinator at ÍSOR: Steinþór Níelsson, Geologist.

The aim of this project is to drill deeper into the geothermal areas, as far as 4-5 km and study the possibility for utilizing energy from lower depths than previously. Three sites will be examined; the Reykjanes geothermal area in Iceland and geothermal areas in Valence and Vistrenque in France.

In Reykjanes, the plan is to clean a 2.5 km deep production well, cast it with steel at a depth of 3 km and then continue to 4-5 km. The aim of the project is to prove that energy can be produced from deep, stimulated geothermal systems. Two possibilities will be explored. Firstly, the utilization of steam from the well for the Reykjanes power station and secondly, to exploit the well for pumping cold water down to 4-5 km depth and thence employing the heat of the rock to increase the production ability of the area from the current wells which are as deep as 2-3 km. A large part of the project involves the increase in the permeability of the rock from that depth and up to the current depth of the area.
