CCS Strategy & Activities

Transcription

1 GeoCapacity project Conference Copenhagen October 2009 CCS Strategy & Activities Professor Niels Peter Christensen Chief geologist Vattenfall Vattenfall A/S

2 Why CCS? Fossil fuels today provide about 80% of the global energy consumption og 2/3 of the power generation. Renewable energy is projected to become increasingly important but must be supplemented by other measures to ensure early and sufficient CO2 reductions. Hydro 17% Global power generation (%) Nuclear 17% Wind & bio < 2% China installs 1700 MW coal power weekly Capacity for new-build wind is 400 MW per week Fossil 64% CCS is an important part of the portfolio of reduction measures required to keep global warming below 2 degrees. Vattenfall A/S

3 CCS delivers 1/5 of the lowest-cost GHG reduction solution in 2050 Vattenfall A/S

4 The Vattenfall CO 2 vision making electricity clean CO 2 neutral energy production Vattenfall Nordic by 2030 (Denmark, Sweden, Finland) Vattenfall Europe (Germany, Poland) - 50% reduction by CO2 neutral by 2050 Vattenfall Netherlands yet to be defined Current emissions of CO 2 are about 95 million tonnes p.a. Vattenfall A/S

20 Meeting with GFZ Potsdam 11 June 2008 Investigation of the geological structure at Vedsted, North Jylland Denmark By: K. Zinck-Jørgensen Representing: GFZ, Shell, SLB and GEUS Niels Peter Christensen - chief geologist Vattenfall Nordic Professor in CO 2 storage at Heriot-Watt University Skotland

22 Cross-section through the Vedsted geological structure Storage must be at least 700 meters deep to ensure CO 2 to be in supercritical state Vedsted-1, Oil exploration well from 1958 CO 2 in fluid form is pumped into the well Haldager-1, Oil exploration well from 1950 CO 2 is stored in porous Sandstones covered by thick sections of impermeable claystones -1 km Porous sandstone -2 km -3 km Cross section courtecy of GEUS
