Comments: As reflected by the acronym, CCS require three different operations:
- Capture: The Capture of the CO² is not always easy, it depends very much where the CO² comes from, mixed with Oil & Gas, produced out of a transformation process (gas turbines, chemical, etc…).
Closer from the source is the Capture, easier it is.
- Compression: To extract or transport the CO², it requires large compressors for which leaks are not an option.
Their operations must be well adjusted to the process from where the CO² is produced
- Sequestration: This operation needs long time ahead preparation to identify empty reservoirs, normally over aged oil & gas fields, or geologic pockets which could be proof enough to contain for decades this CO², so that this storage cannot cause environmental damages.
All these three operations supposes to mobilize advanced technologies and experience as illustrated by the picture above from Total installation in Lacq, France.
