Carbon seize, utilisation and storage (CCUS) applied sciences are an essential resolution for the decarbonisation of the worldwide power system because it proceeds down the trail to internet zero emissions. CCUS can contribute to the decarbonisation of the commercial and energy technology sectors, and may unlock technology-based carbon dioxide (CO2) elimination. Nonetheless, its profitable deployment hinges on the supply of CO2 storage. For widespread CCUS deployment to happen, CO2 storage infrastructure must develop on the identical pace or sooner than CO2 seize amenities.
CO2 has been injected into the Earth’s subsurface for the reason that Seventies and devoted CO2 storage (the place CO2 is injected for the aim of its storage and never for CO2-based enhanced oil restoration) has been occurring since 1996. There are seven commercial-scale devoted CO2 storage websites at present, with greater than 100 others in growth. Classes realized from these websites, together with analysis, pilot and demonstration initiatives, contribute to our understanding of CO2 storage assets, their evaluation and their growth into CO2 storage websites.
This IEA CCUS Handbook is an support for power sector stakeholders on CO2 storage assets and their growth. It supplies an summary of geological storage, its advantages, dangers and socio‑financial concerns. The handbook is supported by an in depth glossary of CO2 storage-related terminology discovered on the finish of this report and enhances the IEA CCUS Handbook on Legal and Regulatory Frameworks.
