The 6th International Workshop on Offshore Geologic CO₂ Storage was held in Aberdeen on 13-14 September. Organised with the University of Texas and hosted by the University of Aberdeen. The loca on was very appropriate as we were co-hosted and sponsored by Storegga who leads the Acorn project nearby in Scotland. This project had been recently announced by the UK government as a Track 2 Cluster project. This 6th workshop had 190 delegates (60 in-person and 130 virtual) from 35 countries, with a good mix of industry, researchers and regulators.
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 CO<sub>2</sub>, 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
The 4th International Workshop on Offshore Geologic CO₂ Storage was held 11-12 February 2020, hosted by the University of Bergen in conjunction with the EU-Funded STEMM-CCS project in Norway. The workshop addressed how to develop CCS projects with offshore storage and built on the recommendations and topics raised at the previous workshops. The aim of the workshop series is to facilitate sharing of knowledge and experiences among those who are doing offshore CO₂ storage and those who are interested, and to facilitate international collaboration on projects. Over 150 attendees from 18 countries participated in this 4th workshop.
This workshop came about to address a recommendation from the CSLF on offshore CCS. This 3rd International Workshop on Offshore CCS took place on 3-4 May, organised by the Bureau of Economic Geology (BEG) in collaboration with IEAGHG and others, and hosted by the Research Council of Norway in Oslo, with support from SANEDI and CSLF.The aim of the workshop series is to facilitate sharing of knowledge and experiences among those who are doing offshore storage and those who are interested, and to facilitate international collaboration on projects. Over 60 attendees from 8 countries participated in this 3rd workshop.The agenda included: How to learn from learnings?; Value Chains for Offshore; Infrastructure re-use; Monitoring offshore CO₂ storage/EOR; Offshore CO₂ storage resource assessment; Project updates; Standards and Regulatory Frameworks; and Brainstorming towards an international collaborative project.
This second workshop built on the conclusions and recommendations from the first workshop in 2016 by continuing the theme of ‘how to do’, and including sessions on how to find storage, monitoring developments, CO<sub>2</sub>-EOR potential offshore, and infrastructure options, with presentations from Norway, the UK, the Netherlands, Australia, South Africa and Japan. New to all attendees were presentations on the US Department of Energy (DOE) -supported US projects looking at offshore storage in sedimentary basins in the Gulf of Mexico, the Atlantic and in basalts in the northern Pacific. Conclusions and recommendations were agreed, with a certain focus on infrastructure issues with the aim of engaging with operators of offshore infrastructure to make them aware of the opportunities from CCS and CO<sub>2</sub>-EOR.
The aims of the workshop were to undertake a global needs assessment for offshore geological CO₂ storage, to initiate a discussion about the various aspects of offshore transport and storage, and to build an international community of parties interested in offshore storage. This was achieved by bringing together those who are doing offshore CCS to share knowledge with those who are interested in doing, and by facilitating countries to identify their specific issues, challenges, opportunities, and then to identify synergies, common gaps and goals, and define common action items.
