2 Project History German Government: Target of expanding the proportion of renewable energy in the energy supply mixenergy energy Support of R & D measures in various fields including deep geothermal energy (BMU) Development of a digital geothermal atlas which provides of geothermal atlas provides essential information for deep geothermal project planning Available via Internet (free success) since System is continuously updated, expanded and developed further Geothermal Energy in Germany NEAR SURFACE GEOTHERMAL ENERGY (max. 400 m) m) C Heating (heat pump) Cooling HYDROGEOTHERMAL ENERGY 20 District Heating Deep Aquifers 150 C Power Generation PETROTHERMAL ENERGYENERGY Enhanced Geothermal Systems Bedrocks >150 C Power Generation District Heating

3 GeotIS: Objectives Public data base with essential information for deep geothermal project planning planning Tool to increase the quality of geothermal project planning and to improve the possibility of success Minimize exploration risks Provide an overview of installations using deep geothermal and the energy produced energy GeotIS cannot replace detailed local feasibility studies! Exploration Risk = Risk, to develop a geothermal reservoir with an insufficient quantity or quality by one or more drillings. Quantity P ~ Q T Installed capacity: P = F c F Q (T (T i T o ). P = power/ capacity [W] F F = fluid density [kg/m³] c F F = = specific heat capacity [J/kg capacity [J/kg K] K] c F Q = flow rate [m³/s] T i, T 0 = input and output temperature [ C, K] Quality is determined by the composition of the fluid Success: sufficient discharge rate and temperature, acceptable drawdown, acceptable water quality
