As part of the Carbon Dioxide Transport and Storage licence, Licensees may re-open their allowance for devex, under the Ongoing Devex Re-opener uncertainty mechanism, if the associated development activities were divided into Tranches of Ongoing Devex Stage Check Activities.
In July 2025, Net Zero North Sea Storage Limited submitted an application for an On-going Devex Re-opener pursuant to Special condition J5.5 of the Licence. In the submission, the Licensee requested to progress to the next stage of development for an additional two offshore carbon dioxide storage areas, CS006 and CS007. We consulted with the licensee on our draft determination.
Our decisions, having taken account the consultation feedback, are set out in this Final Determination.
