Section 6.3: Geological Storage

The Centre for Geological Storage CGS researches whether and how the geological subsurface could be safely and sustainably used for storage of matter and energy. Research focusses on the permanent geological storage of CO2, but the research portfolio also covers other topics of geological storage. These include, among others, the temporary or dynamic storage of CO2 in the frame of CCUS (“carbon capture usage and storage”) and/or “power-to-gas” concepts and the storage of hydrogen. The centre researches and develops new monitoring technologies for subsurface storage in porous rocks and studies the interactions between rocks and fluids. Together with national and international partners the centre runs and operates the first European on-shore pilot site for CO2 storage at Ketzin/Havel (Federal State of Brandenburg) providing a world-class research infrastructure. Here, research aims at answering the question whether safe long-term geological storage of CO2 is possible and whether it could be implemented with quantities necessary to meet the required reduction of the greenhouse gas emissions. A strong focus is on the different geochemical and geophysical monitoring techniques. Central is not only the combination of different methods as geoelectric, seismic, temperature and pressure monitoring and fluid and gas sampling but also the combination of different layouts with different spatial and temporal resolution within each method. Due to our strong integration in national and international networks we are also scientifically involved in other storage sites. Within running projects, our expertise gained in the frame of permanent geological storage is transferred to other usages of the geological subsurface.
