Global Storage Capacity Workshop 2021

Publication Overview

The aims of this workshop were to review current methodologies and initiatives for quantifying CO₂ geological storage, review current data availability and assess gaps, establish core international contacts and a community with direct interest in CO₂ storage resource. The workshop also discussed opportunities on how to address the identified data gaps in various parts of the world, through either bilateral or multilateral collaboration and via an international network to collate and refine estimates of CO₂ storage capacity.

Publication Summary

Key messages from the workshop include:

• Data exists in several countries, but access is not always clear
• Data availability is a key factor
• In terms of the status of current data, themes raised in the discussion were:
  • Legacy wells and plugging data
  • Dynamic capacity and injection rates
  • Pressure fronts cross-border
  • Plume migration cross-border
  • Digitisation of data
• A better understanding of what countries are looking at CCS as a priority and how can international initiatives be effective
• More refinement is needed in dataset content, access and quality
• The digitisation of paper-based data would be a huge benefit
• Priorities identified include:
  • Industry view is to emphasise project-specific work (as opposed to total country coverage)
  • Looking at emerging countries with little or no hydrocarbon exploration (and hence limited data of relevance for storage resource assessment)
  • Harmonising terminology and methods of communication (in terms of language, word choice matters and terminology)
• The choice of vehicle and establishment of a key lead group to drive this effort will be essential
• A clear and credible implementation plan should be established
  • Timeline and actions towards CEM-13 (2022)
