Co2 energy storage application areas

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.

Where is CO2 stored?

In the CTS, 93% of the captured CO 2 is permanently stored in geological formations and the remainder (7.9 Gt CO 2) is used in processes such as methanol production. Figure 1.

How much CO2 can be stored?

Today, just over 10 Mt CO 2 /yr of captured CO 2 is injected for dedicated storage within ten large-scale sites, but based on the project pipeline planned storage capacity could reach around 615 MtCO 2 /yr by 2030.

What is the geological understanding of CO2 storage sites?

The geological understanding of CO 2 storage sites uses the concept of the storage complex, including fault compartmentalized systems and residual and dissolution trapping for injected plume immobilization.

Why is CO2 storage important?

The IEA underscores the necessity for CO 2 storage, growing from today’s capacity to over 5 Gt/yr by mid-century, making it a global industry essential for emission reduction across the energy system.

Should CO2 storage be limited?

Limiting the availability of CO 2 storage would result in the marginal abatement costs for the industrial sector doubling in 2060 relative to the CTS, from around USD 250 per tonne of CO 2 (tCO 2) to USD 500/tCO 2, due to reliance on more expensive and novel technology options.
