Geothermal energy forms an indispensable link in the renewable energy mix of the future. VITO is building the first deep geothermal energy plant in Flanders and will supply pioneering work in order to roll out geothermal energy on a large scale in Flanders.

It is well known that deep geothermal energy can cause earthquakes. These are usually mild earthquakes that can only be recorded using sensitive measurement equipment. The injection of cooled water appears to be a significant cause of these. By determining the location of the earthquakes, we are able to establish how the substrate responds to differences in pressure in connection with the injection. This allows us to become more familiar with the substrate.

Radioactive elements resulting from the decay of natural uranium and thorium are found everywhere in the Earth's crust. These natural radioactive substances are referred to as NORM, or Naturally Occurring Radioactive Materials.

The geothermal site in Mol uses hot water taken from the substrate. But this water layer, at a depth of 4 km, is only available in the Kempen area of Limburg and Antwerp. How can we resolve this throughout the rest of Flanders? 


Geothermal energy is a local and sustainable energy source that is available constantly. Despite those major advantages, the technology is still not being used on a large scale. VITO teamed up with Grontmij and TNO to investigate what the barriers are and what potential geothermal energy offers in the Flanders-Netherlands border region.

VITO has gained an in-depth knowledge of geothermal energy during the development and construction of the Balmatt plant in Mol, and we now want to share that expertise with companies that are interested in using geothermal energy themselves. VITO maps out the likelihood of success of new geothermal energy projects and calculates the profitability.

Geothermal energy, solar energy, residual heat from industry ... these are all sustainable energy sources that complement one another. GeoWatt studies how thermal networks are able to match supply of heat with demand.
