The economic efficiency of geothermal plants is often impaired by depositions of secondary minerals or corrosion damage. A promising countermeasure is the use of inhibitors, which can thereby improve the sustainability and economic use of geothermal plants.

In EIKE we develop an inhibitor combination from available basic chemicals. Compared to commercial products, the combination of pure substances of known composition enables a systematic selection process and targeted studies on the thermal and chemical stability of the product mixture as well as a targeted adjustment to the respective geological and hydrological conditions in the north German basin and in the upper Rhine valley.
