What is Carbon Capture and Storage (CCS)?

Geological storage is a four-step process:

  1. first, a pure or nearly pure stream of CO2 is captured from flue gas or other process stream;
  2. next it is compressed to about 100 atmospheres;
  3. it is then transported by pipeline to the injection site;
  4. and finally, it is injected deep underground into a geological formation such as an oil and gas reservoir where it can be safely stored for thousands of years or longer.

Overview of Geological Storage Options

Storage Options

  • Depleted oil and gas reservoirs
  • Enhanced oil and gas recovery
  • Deep saline formations
  • Enhanced coal bed methane recovery
  • Deep unmineable coal seams
