                                           GEOTHERMAL INNOVATION

The Rittershoffen project (Alsace, France) is an EGS project supplying heat to a local starch producer and biorefinery.

1.	 Increase reservoir performance14           €ct/kWhth for heat by 202515;         exploration; deep drilling;
    resulting in power demand of                                                     reservoir performance, production
    reservoir pumps to below 10% of        4.	 Reduce the exploration costs by       and well field development, including
    gross energy generation and in             25% in 2025, and by 50% in 2050       reservoir, operation flexibility,
    sustainable yield predicted for at         compared to 2015;                     corrosion and scaling; surface

                                           5.	 Reduce the unit cost of drilling (€/  environmental issues.
2.	 Improve the overall conversion             MWh) by 15% in 2020, 30% in 2030
    efficiency, including bottoming            and by 50% in 2050 compared to        Concrete steps can be taken to bring
    cycle, of geothermal installations at      2015;                                 geothermal technologies to full
    different thermodynamic conditions                                               commercial scale and to allow for

                                               economic feasibility of responding    the Deep Geothermal ETIP and its
