In-Situ Durability Testing of Geo-Coat Developed Coatings!

Tue, 16 February, 2021

As part of the Geo-Coat workshop: Geo-Coat: Materials Challenges in Geothermal Energy Production, Dagur Ingi Ólafsson from Innovation Center Iceland will present on "In-situ durability testing of Geo-Coat developed coatings"


Various degradation mechanisms occur in geothermal powerplants and the mechanisms greatly differ between different plants and within different systems of the same plant. The complexity of geothermal reservoirs and the conditions faced by engineering materials makes it difficult to accurately recreate these conditions in laboratory experiments. In-situ durability testing exposes material to actual geothermal environment within a geothermal site. Although they can be more difficult to control in comparison to laboratory experiments they provide an important insight into how durable the materials are in actual environment and can help confirm the laboratory findings. As a part of the Geo-Coat project, ICI and ON conducted several different in-situ durability tests on the developed and down-selected coatings. In this 30 minute talk, Dagur Ingi Ólafsson at ICI will give an overview of the various in-situ tests conducted, the subsequent analysis made and some of the main results.

About the speaker:

Dagur Ingi Ólafsson is a project manager working in the field of material science and geothermal power at Innovation Center Iceland (ICI). He received his B.S. degree in Mechanical Engineering in 2015 from the University of Iceland and his Masters degree in Mechanical Engineering in 2018 from Aalto University in Finland. Dagur has been working in geothermal research projects at ICI for three years, during which his main focus has been on the in-situ corrosion testing of various metal alloys and coatings in geothermal environment. Dagur is the project manager for ICI in european research projects such as Geo-Coat, GeoHex, MEET and GeoSmart.
