Webinar: The Bunter Sandstone Formation – CO2 storage in an extensive hydraulically-connected saline aquifer

The Bunter Sandstone Formation (BSF) is a primary target for planned CO₂ sequestration projects in the Southern North Sea, UK. The BSF provides a storage option for many of the blocks offered in the North Sea Transition Authority (NSTA) 1st carbon storage licensing round and is expected to play a crucial role in decarbonising the UK’s major industrial hubs, such as Teesside and Humberside.

This webinar focused on the current understanding of the Bunter Sandstone Formation, highlighting the structural and geomechanical controls that will influence storage development. These geological constraints will be considered alongside the UK regulatory framework and the requirement for strategic use of the subsurface to deliver the Government’s net-zero ambitions. A series of presentations, from the British Geological Survey, industry and other key stakeholders, explored these topics. Subsequently, the main challenges and uncertainties faced in the development of storage projects in the Bunter Sandstone Formation were considered, reviewed and debated by an expert panel.

There was also an opportunity for attendees to take part in a dedicated Q&A session with the panel of presenters after the talks. The webinar was open to all, and anyone interested in current and future CO₂ storage development in the UK was encouraged to attend.
