Scaling phenomenon at Soultz in a small prototype exchanger

The aim of the Soultz-sous-Forêts Geothermal Power Plant (SGPP, Upper Rhine Graben, France) is to optimize the exploitation of a fractured granitic reservoir (Figure 1), while minimizing environmental issues. In MEET project, this demo-site is tested for enhancing energy production. To this aim, the temperature of the reinjected fluid is to be lowered from 70°C…

Organic Rankine Cycle installation in Vermilion site (Chaunoy, France)

A part of MEET project consists in the the demonstration of electricity and thermal power generation from various geological contexts. Six demonstration sites were selected based on temperature, flow and geological environment. The first demonstration sites are Chaunoy (France, sedimentary geological context), Soultz-sous-Forêts (France, granitic geological context) and Reykjanes (Iceland, volcanic geological context).  On these…
