4 The increasement and sustainable utilization of geothermal energy in Hungary Geothermal community heating: 25 MW capacity (Miskolc 6 MW, Győr 52 MW ) Geothermal energy in agriculture: 29 MW capacity The geothermal potential of the producing medicinal water wells (around 25): 225 MW Geothermal power plant capacity: one ongoing EGS project, MW el Mainly thermal water related (hydrothermal) projects can be expected in Hungary in the near future the importance of hydrogeology Sustainability issues and technical challenges in the main focus of the experts

6 Well-known fact the geothermal energy potential is high in Hungary Dövényi et al Estimated temperature at 5 5 km depth W Elevation a.s.l. (m) H Duna land surface hydraulic head contour (m a.s.l.) with direction of fluid driving force x exagerated elevation (m a.s.l.) H' 1 Szeged Tisza top of Pre-Neogene basement with fault -5 -Deep over-pressured flow Distance from systems western end of cross section (km) H 2? H'' Tóth and Almási 21 originated from the Pre-Neogene basement -Superimposed, shallower, gravity-driven flow system Unique natural groundwater laboratory József Tóth (vertical exageration: M h M v = 1 ) Temperature at the basin bottom (Szanyi and Kovács 27) E C o

7 Overproduction of the Upper-Pannonian thermal water aquifers in Hungary Sustainability aspects Simulated depressions in the Upper-Pannonian aquifers based the national scale flow modeling - Tóth Gy. 212 Less than 1 % of the produced thermal water for energy purposes is injected back into the aquifers Our thermal water resources are not endless

8 Good example for sustainability 1 % injection rate into a karst aquifer system Geothermal Project of Miskolc well parameters MAL-PE-1 production well Depth: 235 m Fluid temperature: 15 C Yield: 66-9 l/min. MAL-PE-2 production well Depth : 1514 m Fluid temperature : >9 C Yield: 8 l/min. KIS-PE-1 reinjection well Depth : 1737 m Receiving capacity: 16 l/min. KIS-PE-1B reinjection well Depth : 193 m Receiving capacity : 56 l/min. KIS-PE-2 reinjection well Depth : 158 m Receiving capacity : not a final result ~7 l/min. Miskolci Geotermia ZRt - Pannergy Geothermal community heating: 6 MW capacity

9 Concession application is required for the geothermal energy utilization bellow the depth of 25 m in Hungary Moderate interests from the potential investors

10 Ongoing concession work by EU-FIRE at Battonya to build the first geothermal power plant in Hungary EGS geothermal power plant is proposed Binary ORC geothermal power plant around 9 MWe Ádám László 217.
