GEMex (Cooperation in Geothermal energy research Europe-Mexico for development of Enhanced Geothermal Systems and Superhot Geothermal Systems) was a Horizon 2020 project, funded by the European Union.

Its ambition was to bring together extensive Mexican know-how in the discovery, development and use of conventional geothermal energy systems with a variety of European expertise from similar geothermal energy systems (Italy, Iceland, etc.), to develop EGS technology, and to find new approaches to make use of superhot geothermal systems. The approach led to concepts for extensive future development of geothermal energy in Europe and Mexico. This was done through the development of common sites, one for hot EGS (Enhanced Geothermal Systems) and one for SHGS (Super-Hot Geothermal Systems). This approach opened up synergies of skills and technologies and led to an acceleration of the learning curve for geothermal development. Potential drilling routes were developed in the target areas in order to maximise the scientific result. The results were compared with extensive experience in EGS projects in Europe and elsewhere and with the few SHGS projects in Europe (IDDP1) and Japan (Kakkonda).
