News From GeoHex Community

Fri, 12 June, 2020

Geothermal are naturally aggressive environments. The geofluids, due their inherent chemistry, cause corrosion and scaling issues in critical plant components such as heat exchangers (HXs) adding to capital costs as well reducing the overall efficiency of geothermal power plants. Project GeoHex, an international initiative funded under the EU’s Horizon 2020 programme (Grant agreement 851917), explores opportunities to improve anti-scaling and anti-corrosion properties as well as heat transfer performance of the HX material that could lead to smaller, more efficient and economical systems.

The consortium is pleased to announce the publication of its first Newsletter. Scroll down to find out about how GeoHex contributes to:

Sustainability of geothermal heat exchangers

Using low cost carbon steel as base materials and the modification of its surface chemistry through nano-porous coatings, GeoHex is working towards a technology that can improve heat transfer as well as anti-scaling and anti-corrosion properties of heat exchangers. Discover more

Climate action and green economy

The use of geothermal resources aligns with global goals for sustainable development by helping to provide affordable and clean energy. GeoHex contributed to the exploitation of this resource by addressing material challenges to improve the efficiency of critical components for competent and economical geothermal systems.
