From Exploration to Operation - Research Developments in Deep Geothermal Energy

New Content Item

The potential for geothermal energy to supply clean base-load energy for heating and electricity worldwide is enormous. If developed appropriately, geothermal energy will play a decisive role in the global switch to renewable energies. However, geothermal energy exploitation remains complex and requires the active participation of experts from a variety of fields. Indeed, key to the development of efficient and sustainable geothermal energy is the pursuit of new integrative approaches. The 6th European Geothermal Workshop - held on 10-11 October 2018 in Strasbourg, France - brought together members from this practice-oriented and diverse research community to discuss interdisciplinary research aimed at advancing all stages of geothermal energy production from exploration to operation. 

This EGW 2018 Special Issue is a collection of scientific contributions initially presented at the 6th European Geothermal Workshop.

  1. The present study aims to understand the potential of a new and novel type of geothermal play system for high temperature and electricity production: crustal fault zones (CFZ). According to geological and geop...
