At Lonquist, our team works at the intersection of traditional energy development and emerging carbon capture and storage (CCS) applications; it's the kind of applied subsurface work we do. Consider this article to be a plain-English guide for anyone trying to understand what sequestration means when evaluating CCS feasibility.
Salt caverns are fascinating geological formations that are created through a natural process known as "solution mining." The formation of salt caverns began millions of years ago, with the deposition of ancient oceans and seas.
The injection process starts at the CO₂ source: a power plant, cement facility, or industrial operation where CO₂ is captured from the flue gas stream. From there, the CO₂ is compressed to its supercritical state, transported via pipeline to the injection site, and pumped down a Class VI injection well into the target formation.
