The presentation shall be focussed on EGS development on an industrial and economical point of view. Based on recent experiments in the Rhine Graben area (Soultz-sous-Forêts, Landau), basic investment costs for a 2 wells system at 3000 m depth shall be estimated. Power and/or heat generation shall be considered and the tariff issue shall be discussed taking into account the specific problem of auxiliaries’ consumption in the case of EGS. As a conclusion, a rapid comparison with other subsidised renewable energies (wind, solar) shall be presented and pros and cons of EGS shall be highlighted.
