5th International Workshop on Offshore Geologic CO₂ Storage

Publication Overview

This 5th Workshop on Offshore Geologic CO₂ Storage covered multiple subjects, including: summary of multiple CCS projects worldwide, subsurface considerations for depleted hydrocarbon fields, containment/ pressure management, and saline formations to store CO₂, as well as considerations on regulating offshore CCS, monitoring offshore CCS projects, CO₂ shipping and infrastructure for CO₂. Importantly, this is the first hybrid in-person and virtual workshop, which represents a milestone to bring this knowledge sharing to multiple people interested on CCS worldwide

Publication Summary

The following conclusions and recommendations were agreed by the workshop delegates.

Conclusions from this workshop:

The growing number of projects since last workshop. We are in a momentum.
The range of projects in design and coverage of emissions. Good for others to learn from.
Some project planning to use shipping for transport and/or injection.
Good participation by regulators in this workshop, i.e., BSSE, BOEM.
New industry players coming in, with new interest and ideas.
Re-use of infrastructure is complex, technically and legally. Good examples of the details needed from some projects.
Can we co-locate activities, i.e., CCS projects with wind farms? It can be complex and not always possible.
Good display on the use of environmental monitoring research outputs for real projects (STEMM-CCS and ECO₂ to Northern Lights, Greensand, Northern Endurance Partnership).
Northern Lights environmental monitoring plan, ‘down-selecting’ from R&D projects, so as to be ‘fit for purpose’
