4.2.5 The Jänschwalde project (Germany)

The Jänschwalde, integrated full CCS chain project of Vattenfall, now completely cancelled, was originally supported by the EEPR, like ROAD and a number of other European demo projects. Approximately 1.7 million tonnes of CO2 was planned to be captured from a lignite-fired power plant in NE Germany, transported via a pipeline and stored in an onshore saline aquifer of Bunter Sandstone at a depth of about 1.3 km.

The non-confidential FEED study (CCS Demonstration Project Jänschwalde, 2011) does not include a detailed monitoring plan, rather the scope of the site appraisal/preliminary characterization and (some) baseline surveys. Four deep and three shallow monitoring wells were to be drilled, 3D and 2D seismic and VSP to be shot and hydraulic tests of injection and extraction of brine were planned. Groundwater monitoring was designed, based on comprehensive archive data, to assess the possible impact of CO2 injection and brine displacement on groundwater resources. The baseline groundwater monitoring was going to be re-evaluated and repeat campaigns were foreseen on an annual basis.

The relation between monitoring with risks and with modelling was not presented explicitly in the non-confidential FEED study, but a statement was made that the DNV CO2QUALSTORE JIP guidelines were to be followed.
