Brief description:

Following the commitments made by the Kyoto Protocol, EU countries are challenged to reduce their emissions of CO2 by 8% during the period 2008 to 2012. There are several options for CO2 reduction in the power and heat sector. However, CO2 capture and geological storage is the only one that has the potential to achieve substantial CO2 reductions at acceptable cost levels over the next few decades. To address and alleviate potential public concerns about the safety and environmental impact of geological storage, a better understanding of CO2 storage is needed.

The CO2SINK integrated project, supported under the FP/6 framework by the EU commission, aims to develop the basis for this storage technique by injecting CO2 into a saline aquifer near the town of Ketzin, west of Berlin. The project will develop an in situ laboratory for CO2 storage to fill the gap between the numerous conceptual engineering and scientific studies on geological storage and a fully-fledged onshore storage demonstration. The project started in April 2004.

To characterize the underground and understand the processes which happen there, detailed analysis will be made of samples of rocks, fluids and micro-organisms from the underground. The project involves intensive monitoring of the injected CO2 using a broad range of geophysical and geochemical techniques, the development and benchmarking of numerical models, and the definition of risk-assessment strategies. These steps will all help to evaluate the reservoir's stability and integrity.
