- GDF Latin America (Germany), the first multi-donor climate initiative offering risk mitigation for surface studies and appraisal drillings during the exploration phase of geothermal projects in Latin America. The Lead Geothermal Project Manager is Warren T. Dewhurst, Ph.D., P.E., a GRC Board member.
- GPC Instrumentation Process (France), for the design and implementation of the first sub-horizontal well in a geothermal project, a technique so far only used for oil drilling that allows to drain more hot water over a long length.
- Politecnico di Torino (Italy), for their system ENERTUN, that allows transforming a tunnel lining into a low enthalpy geothermal system.
- PORCIÓ Ltd. (Hungary), for the Gyopáros Production and Reinjection Geothermal System, in operation at Gyopáros Thermal SPA.
- RWTH Aachen University (Germany), for the development of their Temperature Sensor Module (TSM) for detecting groundwater flow velocity and direction near a borehole heat exchanger.
The Jury will now deliberate to select an overall winner which will be announced on 1st March at the GeoTHERM expo & congress in Offenburg (Germany).
