How many CO2 storage sites are there?

CO 2 has been injected into the Earth’s subsurface since the 1970s and dedicated CO 2 storage (where CO 2 is injected for the purpose of its storage and not for CO 2 -based enhanced oil recovery) has been occurring since 1996. There are seven commercial-scale dedicated CO 2 storage sites today, with more than 100 others in development.
