8.4 Progressing storage projects
Progressing CCS projects and CO2 storage in general can be accelerated by transferring knowledge and experience gained from existing projects, large or small, to other projects in various phases of development. In particular, many of the smaller research programs involving injection have contributed significantly to development of monitoring capabilities, characterisation criteria, and refining modelling and simulation tools. The coordination of technical needs and fostering the transfer of findings among research and industrial communities is of paramount importance to the broader CCS community.
Although many of the technologies involved in storage are mature, there are still numerous uncertainties associated with characterising deep saline formations, modelling and predicting long-term behaviour of CO2 in the subsurface, and monitoring and verification procedures at the large spatial and temporal scales involved in CCS. Targeting specific topics and supporting research in these areas is one mechanism thepursues, both independently and in association with technically focused agencies such as the IEAGHG R&D Programme, CO2CRC, and others. For example, the Global CCS Institute currently sponsors targeted work to describe and catalogue relative analyses for use in dynamic simulation, and supports a study on options for remedial techniques in the subsurface. Findings from these studies, along with other project-specific reports supported by the Institute, are available on the Institute’s website.
The development of standards, such as the CSA Standard Z741 – Geological Storage of Carbon Dioxide and emerging work by the ISO on CCS, may provide additional confidence to both proponents and regulators in many jurisdictions to proceed with planning of CCS projects. Guidelines andemerging from existing research and commercial projects are also highly instructional in formulating screening and characterisation strategies and with developing risk management plans to inform operations and monitoring activities. Lessons from these storage activities can provide many insights to progress future CCS projects more rapidly.
Ultimately, capacity development by transferring knowledge through reports, webinars, and workshops is critical. The Global CCS Institute is active in all these areas as well as having a strong focus on providing workshops and courses on storage and CCS in emerging economies.
