What is Geological Sequestration?

Go ahead and try it. Ask a friend “What’s geological sequestration?” You might get a confused look or a “huh?” in response. If you’re lucky you might get a stab at an answer, but is it right?

This website is here to answer your questions about the process called geological sequestration, or carbon capture and sequestration, or carbon sequestration, or GS, or CCS. Even giving it a name gets confusing!

That’s why we went to experts. This website will give you the straight facts about carbon sequestration, and identify the people who stand behind those facts. You can choose a more general answer if that suits your purposes. If you need more technical information--the kind you can't find on Wikipedia--we've got that too. And we'll show you places to look if you want to dig deeper, though maybe not as deep as a geologic reservoir (see FAQ How far underground will you store CO2? if that doesn't make you grin).

Who are we? We are a group of scientists and engineers who study carbon sequestration from smokestacks down to geologic formations. This website was conceived at the Gulf Coast Carbon Center of The University of Texas at Austin as part of our STORE outreach initiative.  We have collected information from the best possible sources all over the world and all of our FAQs are reviewed by experts. In some cases, we are the experts, but in other cases we ask for expert review from additional institutions or industry.

Help us expand our website. If you'd like to weigh in on the CCS topics that interest you most, please take our quick survey and we'll use your feedback to develop our FAQs. Thanks!

When you look around this site you'll see a few different types of icons. Here's a rundown of what it all means.

WANT TO READ MORE? Most of our answers come in two sizes: short and longer. If you just need the nuts & bolts, you'll find that out right away. If you are still curious for more detail, click WANT TO READ MORE? and you'll get an answer with more depth. 


This icon means that a scientist or researchers who is an expert in the field has approved our answer to the FAQ. We include the person's name and a link so that you can read more about that person and the research that he or she does.



When you see this icon, it means that we've checked another website for accuracy. We may suggest you look there for more information or a different perspective, and you can depend on the link as a quality source. For example, if you click on the link to the right, you'll be directed to a CCS program that's developed an extensive, but easy to understand glossary of terms having to do with CCS.
