Modularised logic tree risk assessment method for carbon capture and storage projects

We suggest CCS risk assessment should extend beyond the primary container to address a wide range of safety, economic, social, political and engineering issues. In New Zealand, for example, past experiences of large engineering projects suggests that failure to gain public support or to allocate appropriate resources to navigate through legislative process could provide significant barriers to successful CCS implementation. We have developed a modularized and probabilistic based logic tree which encompasses the main components of CCS (capture, transport, injection and storage) and is built upon the five issues mentioned above.
