CO2 Injection and Storage- short and long term behaviour at different spatial scales

This is an interdisciplinary project which aims to enhance our knowledge of the risks associated with the geological injection and storage of carbon dioxide (CO2). Cardiff University is leading work package four of the project, focused on expert and public risk perceptions. More technically focused work packages are being led by Imperial College London, involving researchers from Leeds University, Heriot Watt University and the British Geological Survey.  The project is funded by the Engineering and Physical Sciences Research Council (EPSRC)

Cardiff’s contribution to the project focuses specifically on expert and public perceptions of CO2 injection and storage as an emerging technology for climate change mitigation. CO2 injection and storage is a part of a wider process known as carbon capture and storage (CCS). CCS involves capturing emissions of CO2 from power plants and industrial facilities, compressing, transporting and injecting it deep underground- thus preventing it from contributing to anthropogenic climate change. CCS has been recognised by many governments and international agencies as a promising technology for climate change mitigation. Research into the technology is well underway in the UK, and, around the world several demonstrations projects have been running for a number of years.

As an emergent technology CO2 injection and storage remains subject to a number of risks and uncertainties as to its efficacy and safety, and at present it is not clear how these will be received by wider publics. Previous studies have shown trust in experts and governments can be an important factor in various publics’ willingness to accept risks posed by CCS, and that significant disparities may exist in how such risks are perceived. This research thus aims to: a) enhance our understanding of how CO2 injection and storage is perceived by experts and wider publics, and, b) contribute to wider debates and risk assessments on the deployment and sitting of CO2 injection and storage technologies. This will be achieved through a series of expert and public workshops to be held in the summer of 2016.
