As part of the GECO H2020 project, multiple geothermal sites across Europe have been evaluated as potential targets for the application of an innovative technology, recently developed and proved successfully at pilot scale in Iceland, which can limit the production of emissions from geothermal plants by condensing and re-injecting gases or turning the emissions into commercial products. This approach requires the preliminary study of subsurface rocks, fluid composition and residence time, reservoir permeability, and presence of natural analogues nearby the area of interest.
