  1. Potencijal geološkog skladištenja CO2 uHrvatskoj kao jedna od mjera za dekarbonizaciju stacionarnih energetskih i industrijskih izvora Potential of CO2 Geological Storage as a Measure for Reducing Emissions from Energy Production and Industry Sources in Croatia Bruno Saftić FP6 EU GeoCapacity Prof. Bogdan Goričnik Prof. Josipa Velić Doc. Domagoj Vulin V. asist. Iva Kolenković Dragutin Domitrović

  2. Mehanizmi vezanja ugljičnog dioksida u podzemlju: fizički – kapilarni – kemijski – mineralni CO2 trapping mechanisms: structural – residual – dissolution - mineralisation

  3. Carbon Capture and Storage system (CCS)

  4. IPCC/Angus Dense supercritical CO2phase (> 31°C at 73 bars)

  5. Where? • 7 power plants • 1 NGPP Who’s CO2? • HEP • INA Possible impact?

  6. (Prelogović, 1993) (Velić & Velić, 1993)

  7. Pannonian-Pontian turbiditic lobes, slumps, delta front mouth bars, barrier bars, and delta plain channel fills Ottnangian-Pannonian breccias / conglomerates Badenian limestones and tuffaceous sandstones Basement rocks with secondary porosity

  8. I (Saftić et al., 2003)

  9. Capacity estimates: • area • effective thickness • average porosity • storage coefficient = THEORETICAL

  10. Capacity estimates in deep saline aquifers

  11. Capacity estimates in hydrocarbon fields

  12. CO2 emissions and storage capacity estimates (EU GeoCapacity, 2009)

  13. CCS Options for Croatia • EOR project COMMENCED • Depleted hydrocarbon fields –might be effective • Storage potential in regional aquifers is only an approximation … theoretical • Most of effective capacity is in PBS and half of point source emissions occur in coastal parts • “Small is beautifull” • “Customers” in the neighbourhood…
