Progress report on the first European on-shore CO2 storage site at Ketzin (Germany) - Second year of injection

Abstract

The pilot study at the Ketzin site close to Berlin (Germany) aims at in-situ testing of geological storage of CO2 in a saline aquifer. Following site characterization and the drilling of one injection well and two observation wells, the in-situ field laboratory has been fully in use since CO2 injection started in June 2008. After two years of operation, about 36,000 tons of CO2 have been injected. This paper presents the key results from the second year of injection and the interdisciplinary monitoring concept in the frame of the European project CO2SINK (CO2 Storage by Injection into a Natural Saline Aquifer at Ketzin) and accompanying projects. © 2011 Published by Elsevier Ltd.
