Member state HUNGARY-3
Case study Mórahalom
Description Mórahalom has 6 100 inhabitants and has been , in the past 10 years, one of the most dynamically developing regions. A geothermal cascade system was developed to reduce dependency on natural gas by using a renewable heat source. This system consists of two drilled wells, a 1.26 km-deep outflow well and a 0.9 km injection well. Within the project a new district heating system of 2.85 km was established to supply public buildings. The GHG emission is now reduced by 80%.
