Balmatt in Mol

The Balmatt site is located in the northern part of Belgium. A bypass in the main brine circuit will be realized for the evaluation of different coated materials in contact with the geothermal fluid at extraction temperature.


The first drilling at the Balmatt site was done by VITO in September 2015. Geothermal fluid will be used to heat the nearby district area and, if the temperature of the brine is high enough, to produce electricity. In the frame of MATChING, a bypass will be installed onto the geothermal brine circuit for the evaluation of different coated materials in contact with the brine (at extraction temperature).

Coatings with thin surface layers - obtained through optimization of already commercial coatings or specifically developed within the project- will be first selected in the laboratory and then tested at real scale.

The performance of the coatings will be demonstrated through periodic examination, in-situ measurements of corrosion rates and post-exposure lab analysis
