JRG Energy assessed geothermal heating potential for a malting plant in Dunaújváros, located approximately 70 km south of Budapest in the Pannonian Basin — one of Europe’s most prospective geothermal regions. The study evaluated the suitability of naturally porous and permeable sedimentary reservoir rocks for direct-use geothermal, assessing temperature, depth, and permeability requirements against the plant’s process heat demand to identify a viable low-carbon heating pathway.
