This document provides an overview of carbon capture and storage (CCS) and CO2-based enhanced oil recovery (CO2-EOR) projects, highlighting their importance in reducing CO2 emissions from fossil fuel sources, which contribute significantly to climate change. It presents data on current large-scale CCS projects worldwide, emphasizing the need for effective CO2 capture technologies and their potential benefits in both environmental and energy sectors. The document discusses the processes involved in CCS, including capture, transport, and storage of CO2, and the integration of CO2-EOR as a method to utilize captured emissions effectively.
