Can technologies that capture carbon durably store it?

Carbon capture technologies can store carbon for a long time, it’s like putting your toys away in a box and leaving them there.

Imagine you have a big bag full of cookies, these are like the carbon dioxide we put out when we breathe or burn things. Now, carbon capture is like taking that bag of cookies and putting it into a special container so it doesn’t get eaten by ants (or released back into the air).

Now, the question is: Can this container hold the cookies forever?

How long does the storage last?

Some containers are like strong cookie jars with tight lids, they can keep the cookies safe for many years. These are like underground rock formations, where carbon dioxide is squeezed deep inside and stays put.

Other containers might be more like paper bags, if it rains, or gets too hot, the cookies (or carbon) could leak out. This is what happens with some types of storage methods, like putting carbon into old oil fields.

So, whether the carbon stays stored depends on how good the container is and where you put it, just like your favorite toys can stay safe in a box or get lost if you leave them out.

Examples

A factory uses machines to trap carbon dioxide from smoke, then stores it underground like a giant soda bottle.
Imagine catching bubbles in a lake and keeping them there forever instead of letting them float away.
Carbon capture is like using a net to catch CO₂ and putting it in a deep hole where it won't escape.
