The Geo-Coat project – materials, coating and material science for geothermal applications
The brine of geothermal resources provides great opportunities beyond the generation of electricity and heat, e.g. for mineral extractions, but it also entails challenges to the materials due to heat, the mineral content of the brine etc. The geo-coat project is addressing this issue from a material science perspective.
The EU-funded Geo-coat project develops specialised corrosion- and erosion- resistant coatings, based on selected High Entropy Alloys (HEAs) and Ceramic/Metal mixtures (Cermets), to be applied through thermal powder coating techniques (primarily high velocity forms of HVOF / Laser cladding) specially developed to provide the required bond strength, hardness and density for the challenging geothermal applications. It aims to design the new high performance coatings to resist each of the specified threats or combinations of threat, as experimentally derived at key failure points within geothermal runs, and to apply them only to the affected components.
Run by a consortium of 11 partners from various entities, it is coordinated by TWI Ltd from the UK.
