Ketzin covers all aspects of a CO 2 storage site with a focus on monitoring
Portfolio of R&D activities at Ketzin
Project partners since 2004
The CO 2 injection runs safely and reliably start of CO 2 injection: 30.06.2008 CO 2 quality: > 99.7% 2 storage tanks, 50 t CO 2 each injection rates: 24 to 77 t/day 05.06.2011: 49,686 t CO 2 injected
First injection of CO 2 from Schwarze Pumpe Permit by Mining authority (LBGR) for injection of Oxyfuel-CO 2 (Schwarze Pumpe/ Vattenfall) CO 2 quality > 99.7% (before: 99.9%) 9%) Monitoring and well inspection according to authority requests Injection start: May 04, 2011 Test period: ~ 6 weeks Amount: ~ 1.000 tons High media response 20 m
A multidisciplinary monitoring concept is applied Gas monitoring P/T monitoring Geophysical monitoring Seismic Geoelectric Fluid sampling Logging Persistent Scatterer Interferometry t
Persistent Scatterer Interferometry Displacement monitoring based on TerraSAR-X Stripmap data Rural character of Ketzin site is related to fast temporal decorrelation Persistent Scatterer Interferometry (PSI) overcomes this limitation Installation of four corner reflectors in March/April 2011 Lubitz, 2011
Further drilling at the Ketzin site
Further drilling at the Ketzin site Shallow well (2011) Observation well Ktzi 202 Ktzi 203 (planned for 2012) Injection well Ktzi 201 Injection facility 20 m Pipeline Observation well Ktzi 200 Visitor Centre
Shallow observation well June August 2011: Drilling and completion of a shallow well (440m) for above-zone monitoring August 2011: Installation of U-tube sampling system and sensors Further steps: Hydraulic testing and modelling (cooperation GFZ-LNBL in EU project CO 2 CARE)
Shallow observation well Permanent installations: Monitoring string (tubing) U-tube fluid+gas sampling 3 pressure sensors Temperature sensor 440m Tubing remains open for monitoring Entire aquifer (40 m) Scheduled: gas membrane sensor Open to other devices (max. 3.5 )
The way forward: Planned activities On-site gas mixing facility Simulation of a variety of real CO 2 -flue gas compositions Shall cover oxyfuel, pre- and post-combustion processes component concentration [mass ppm] Methanol CH 3 OH 27 Oxygen O 2 15 Hydrogen Sulfide H 2 S 5 Sulfur Dioxyde SO 2 146 Water H 2 O 27 Nitrogen Oxyde NO/NO 2 137 Scale up from few ppm to higher concentrations 1. Run several tracer experiments with only one impurity 2. Run full range of impurities in one go- cocktail
The way forward: Planned activities On-site gas mixing facility Controlled CO 2 release test - Test design considering gp prior simulations (e.g. thermal-dynamic stresses) and HSE issues - Public communication - Release CO 2 (~ day rate) in safe and controlled manner at one Ketzin well - Comprehensive monitoring (well, reservoir, p g (,, above-zone, surface) and test evaluation
Public outreach Transparent information about the Ketzin project and our monitorinig concept and results from the very beginning Increasing number of requests for site visits by interested citizens, scientists, journalists and politicians Peaks at special events, e.g. first delivery of CO 2 from Schwarze Pumpe in May 2011, and due to on-going political debate May 04, 2011
Public outreach Set-up of new Ketzin website (www.co2ketzin.de) Extension of visitor centre and visiting times Annual Open House at Ketzin site - bring researchers e s and local community together Networking with other storage sites welcome
