Final Conference

The final conference of GEMex served as a platform to present and discuss results from the projects and to learn about other researches and projects related to the topics of superhot geothermal sources (SHGS) and hot EGS. Contributions were encouraged and welcome addressing any of the aspects associated with the investigation, development and/or exploitation of such geothermal resources in any part of the world.
