CO2 storage resources and their recovery – Event

0

Carbon Capture, Utilization and Storage (CCUS) technologies are an important solution for decarbonizing the global energy system as it moves towards net zero emissions. However, the successful deployment of CCUS depends on the availability of CO2 storage. For large-scale CCUS deployment to occur, CO2 storage infrastructure must grow at the same rate or faster than CO2 capture facilities. CO2 has been injected underground since the 1970s and dedicated CO2 storage has been taking place since 1996, but only seven dedicated commercial-scale CO2 storage sites are currently operational. In recent years, interest in CO2 storage has grown significantly and more than 100 dedicated CO2 storage sites are currently under development. Lessons learned from these sites, as well as research, pilot and demonstration projects, contribute to our understanding of CO2 storage resources, their evaluation and their evolution into CO2 storage sites.

This IEA CCUS manual is a help for the actors of the energy sector on CO2 storage resources and their development. It provides an overview of geological storage, its benefits, risks and socio-economic considerations. It also highlights actions that can be taken by the public and private sectors to accelerate the assessment and development of CO2 storage resources. The full report will be available for free download on the IEA website on December 2, 2022 at 10:00 a.m. CET.
