Background & context:


Project Summary:

GECO will advance in the provision of cleaner and cost-effective non-carbon and sulphur emitting geothermal energy across Europe and the World.

Project achievements & innovative aspects:

The core of this project is the application of an innovative technology which can limit the production of emissions from geothermal plants by condensing and re-injecting gases or turning the emissions into commercial products. It will be applied by GECO in four distinct geothermal systems in four different countries. Our approach to waste gas storage is to capture and inject the soluble gases in the exhaust stream as dissolved aqueous phase. This acidic gas-charged fluid provokes the dissolution of subsurface rocks, which increases the reservoir permeability, and promotes the fixation of the dissolved gases as stable mineral phases. This approach leads to the long-term environmentally friendly storage of waste gases, while it lowers considerably the cost of cleaning geothermal gas compared to standard industry solutions.
