LOW-BIN: Efficient Low Temperature Geothermal Binary Power (2006-2009)
The aim of this project is to improve costs, energy efficiency, competitiveness and market penetration for binary geothermal power production devices. It will attempt to develop a functioning unit with the Rankine cycle capable of producing electricity with a geothermal fluid of 65+ °C and to increase the energy efficiency (cogeneration) of this type of device. The work will proceed up to the definition of a pre-prototype.
9 partners: CRES (coordinator), BRGM will ensure diffusion of the results for France |

I-GET: Integrated Geophysical Exploration Technologies for deep fractured geothermal systems (2005-2008)
This project deals mainly with the development of geophysical methods for the exploration of high-enthalpy type geothermal resources in varied geological environments – e.g. volcanic (Iceland), deep sedimentary (North German Basin) and metamorphic (Larderello, Italy).
11 partners: GFZ (coordinator), BRGM, CRES, ENEL, GTN, IGG, ISOR |

HITI : HIgh Temperature Instruments for supercritical geothermal reservoir characterization and exploitation (2006-2009)
The aim of the project is to develop and validate tools for downhole physico-chemical measurements under supercritical conditions (T >350 °C) such as found in the Reykjanes geothermal field, in Iceland, where wells some 5 km deep are currently being drilled ("Iceland Deep Drilling Project", IDDP) and where an unconventional, but highly profitable, production of geothermal electricity (water in a supercritical state) is hoped for.

GHEDOM 2 (2005-2007)
The second phase of the GHEDOM project is to develop methods for estimating the geothermal potential of a high-enthalpy field in a volcanic island environment, like that of France's Overseas Départements , and to continue optimizing the surveillance, exploitation and management methods of the Bouillante geothermal field in order to improve and secure the production of electricity.
The conceptual model of the Bouillante geothermal field in Guadeloupe should be improved in the framework of this project. Surveillance of the field's exploitation and of its impact on the immediate environment continues. Digital hydrodynamic and geochemical simulations of the behaviour of the Bouillante field in response to its exploitation and a literature survey relative to the re-injection of geothermal production waters are also planned.
Partners: ADEME, BRGM |
