CO2 storage
CO2 underground
Our globe is warming. Several climate research institutes calculated the temperature increase between two and eight degree Celsius till the end of our century. Cause is the increasing use of fossil fuels, which enforce the greenhouse effect.
In respect to the global development of a renewable energy supply, in the following decades the energy supply will still be dominated by fossil fuel power plants. This has to be treated as environmental friendly as possible. Therefore modern “CO2-free” power plants should be operated and the emitted CO2 should be captured, safely transported and stored. To slow down the increase of CO2 the storage of great amounts of CO2 can be a bridge technology. The geological storage of CO2 is a method during the transfer to an energy supply which is decreasingly based on the combustion of fossil fuels.
The goal: geological storage of CO2 as a bridge into a new energy era
Suitable reservoir and cap rocks have to be identified and examined for a safe long-term storage of CO2. In the framework of the joint venture GeoEn a worldwide unique chance adds up to examine the whole process chain of capture technologies to the storage in saline aquifers and depleted natural gas fields.
The project goals are the development of innovative exploration technologies and efficient drilling and reservoir technologies, the definition of security relevant standards as well as the monitoring of the CO2 expansion in the reservoir and the modeling of the dynamic processes in CO2 storage sites. There is the unique possibility to determine and balance qualitatively and quantitatively the utility conflict as well as the synergies in the combined usage of the underground (CO2 storage and geothermal energy, integrated process chain shale gas – CO2 storage) through the cross-linking with other core topics in the project.

Pilot site Ketzin
The pilot site Ketzin is operated under the head of the Centre for CO2 storage at the German Research Centre for Geosciences in Potsdam. The site is the first and till now unique research opportunity for CO2 storage on-shore in Europe.
