ABERDEEN, UK — Britain’s North Sea Transition Authority (NSTA) has published guidance for carbon storage developers.
The "Guidance for Measurement of Carbon Dioxide for Carbon Storage Permit Applications" provides information to approved licensees on expectations concerning measurement of CO2 injected into a storage site.
Flow rates must be accurately determined, as the information supports modeling of the behavior of the CO2 in the reservoir. Composition of the gas must also be measured to ensure correct payment is made under the Carbon Trading Scheme.
Another document, "Requirements for the Definition of a Carbon Storage Site, Storage Complex and Hydraulic Unit," is designed to help operators determine the extent of their subsurface storage site and focus on the area that must be managed to prevent/detect leakage.
The guidance highlights the need to provide precise definitions of the spaces in which CO2 will be stored and the surrounding areas it must be contained within. Any deviations from the expected CO2 movement and containment should be clearly identifiable so preventative or remedial measures can be taken.
According to the NSTA, the two sets of guidance should help the licensees of the Track 1 offshore/onshore clusters at Hynet and Northern Endurance, and Track 2 at Acorn and Viking (the projects most advanced), but also new licensees.
A consultation is also underway to determine what carbon storage data should be shared and in what timescales to assist development of future sites.
