Abstract
The current state-of-the-art for assessing CO2 containment risk relies on qualitative or semi-quantitative methods using bowtie analysis or Layers Of Protection Analysis (LOPA). Whilst these are more than adequate for screening of sites, a fully quantitative method is desirable to support licensing and ongoing management of risk. This report demonstrates the characterisation of probabilistic failure of geological features and takes full account of dependent failure of geological barriers (which is a failing of current methods), as well as considering explicitly the uncertainty in supporting failure and consequences data. It builds on previous Carbon Capture and Storage (CCS) work and established techniques in the nuclear industry for the quantitative risk modelling of fission product release from containment and, separately, seismic hazards, by trialling the fully quantitative CO2 containment risk evaluation method (D5.3).
