A consortium of partners from the Netherlands, UK, Turkey, Italy and Iceland investigate and demonstrate the potential of re-injecting CO2 into geothermal fields. This consortium program provides the geothermal energy sector with the means to address the climate change challenge through CO2 utilization and storage. The project is funded by national funding bodies coordinated by ERA-Net ACT, for us particularly the Netherlands Agency Enterprise - RVO.

Existing geothermal power plants at Kizildere in Turkey and Hellisheidi in Iceland will be used to test injection of CO2 into geothermal fields by complementary laboratory verification experiments and geophysical modeling. Besides the storage aspect, we investigate whether injection of CO2 can promote geothermal deployment, through maintaining and/or enhancing reservoir pressure, while suppressing scaling, and how the process can be monitored utilizing novel technologies such as the highly sensitive distributed fiber-optic acoustic sensing system (DAS). The project aims at accelerating and maturing CCUS technological applications by developing, testing and demonstrating state-of-the-art seismic monitoring systems at field scale. Those systems and methods can be merged with various types of CO2 geological storage projects.
