Carbon capture and storage

24 November 2021

The carbon capture and storage (CCS) method covers activities that capture and store greenhouse gas emissions in secure geological formations. CCS was also identified as a priority technology in the Low Emissions Technology Statement as large-scale deployment of CCS will underpin new low emissions industries (including hydrogen) and provide a potential decarbonisation pathway for other industries.

The Carbon capture and storage method was made by the Minister in October 2021.

For more information on the method visit the carbon capture and storage method page.

For information on public consultation and consideration of the method by the Emissions Reduction Assurance Committee (ERAC), visit the carbon capture and storage method page on the Department of Industry, Resources, Environment and Energy’s consultation hub.

Issues Register

Whether existing regulatory and approval regimes are sufficient to underpin CO2 storage.
The Clean Energy Regulator (the agency) has undertaken an assessment of Commonwealth, state and territory regulatory frameworks (including monitoring and reporting frameworks) and considers that they function effectively and are sufficient to support carbon storage.
Determining the appropriate length of a crediting period for CCS projects.

The method includes a crediting period of 25 years and in determining this period, the agency and ERAC considered evidence of the scale of capital investment for CCS projects, other economic costs and benefits, and how CCS projects meet the ERF's requirements for additionality under the Offsets Integrity Standards.

The proposed method is currently out for public consultation.
