Science-based data service to accelerate geothermal developments in Hungary

Abstract

Hungary’s rich geothermal resources provide a real option to tackle the present energy crisis, decrease the country’s high gas dependency and decarbonise its heating sector. Nevertheless, geothermal project development faces some barriers, one of the most important ones is the geological risk of the unknown reservoir properties. One powerful tool to mitigate this risk is to increase the knowledge of the subsurface and provide geoscientific data availability to project designers. The presented Hungarian case study shows a systematic development of such data service, comprising a public web-map based geothermal information system (OGRE) and tailor-data packages developed on the basis of an indicator system that considers the 3 most important factors: reservoir types (R), heat market conditions (H) and the rate of exploration (S).
