MOL explores geothermal energy potential at Danube refinery

MOL has launched geothermal energy exploration at its Danube Refinery in Százhalombatta, marking another step in the company’s efforts to make its refining operations more sustainable.

Using advanced 3D seismic technology, MOL’s geologists are mapping subsurface layers in and around the refinery to determine whether sufficient quantities of high-temperature groundwater exist at the right depth and location. If successful, this geothermal resource could significantly reduce the refinery’s energy demand and emissions.

The geothermal exploration area granted to MOL includes Százhalombatta and the Danube Refinery. Therefore, in addition to mapping the entire area, it is logical to specifically examine the geothermal potential of the refinery’s surroundings.

Results of the current surveys are expected within six months. Should the findings prove favourable, MOL will move forward with detailed feasibility studies.

The project builds on MOL’s broader strategy to decarbonise its downstream operations. The company has already commissioned a solar park and a green hydrogen plant at the Danube Refinery.

The green transition starts with reducing emissions from our own operations. After solar and green hydrogen, we are now experimenting with utilizing the Earth’s heat. I am particularly pleased that we can do this in collaboration with our Exploration and Production business unit.

3D seismic surveys, widely used in oil and gas exploration, function similarly to medical ultrasound: artificially generated vibration waves reflect off geological layers, allowing experts to build a three-dimensional picture of subsurface structures.

If proven viable, MOL’s project would be pioneering in Central and Eastern Europe — with only a handful of refineries worldwide currently experimenting with geothermal energy.
