Carbon Capture Utilisation and Storage

Conference on Carbon Capture Utilisation and Storage (CCUS):
  • The CCUS Conference brings together carbon capture and GHG reduction technology decision-makers, scientists and government officials.
  • It involves high-level strategic updates, case studies on emerging technologies, and connect on research in the industry to advance this important technology.
  • The goal of the program is:
    • To raise awareness of diverse global initiatives and projects
    • Promote greater participation in international dialogue
    • To discuss the commercialisation of CCUS/CCS systems


What is CCS?

  • Carbon Capture and Storage, is a technology which captures carbon dioxide (CO2) from the burning of coal and gas for power generation, and from the manufacturing of steel, cement and other industrial facilities.
  • It involves the transportation of CO2 either by pipeline or ship, for safe and permanent underground storage. Thus, it helps in preventing it from entering the atmosphere and contributing to anthropogenic climate change.
How does CCS work?
There are three stages to CCS:
  1. Capture
  2. Transport
  3. Safe underground storage.
1. Capture: 
  • First, the carbon dioxide is removed, or separated, from coal and gas power plants, and from the manufacturing of steel and cement.
  • There are three types of capture:
    • Post-combustion
    • Pre-combustion
    • Oxyfuel combustion
  • It can capture 90% of carbon dioxide emissions.
2. Transport:
  • The carbon dioxide is then compressed and transported to a suitable storage site.
  • The transport is generally carried out in pipelines.
  • Ship transport is also an option for offshore carbon dioxide transport.
3. Storage: 
  • Carbon dioxide is the injected into a suitable storage site deep below the ground.
  • The storage site must be a geological formation that ensures safe and permanent storage.
  • Storage can either take place in depleted oil & gas fields, or deep saline formations.
