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
