DESCRIPTION:In this presentation I will present recent research in my grou
 p on two topics in subsurface CO2 storage.\n\n \n\nIn the first topic I wi
 ll argue that small\, centimetre scale\, heterogeneities in multiphase flo
 w properties will have field scale impacts on the movement of CO2 injected
  underground. I will demonstrate our characterisation and modelling workfl
 ows in application to simulations of CO2 storage sites of the offshore UK.
  In search of a validating case study\, my research group has been reinter
 preting seismic imagery from the Decatur CO2 storage site in the USA. I wi
 ll show results of our application of an interpretation of the time-shifts
  from seismic surveys at this site. This has revealed CO2 migration along 
 faults\, allowing the plume to bypass lower quality units within the reser
 voir.  \n\nIn the second topic I address questions of the representation o
 f CO2 storage resource (pore space) use in techno-economic models used to 
 identify scaleup trajectories and identify climate change mitigation plans
 . I will review the varied uses and demands for resource assessment in the
 se projections and discuss the potential for including simplified physics 
 and techno-economic constraints on the use of subsurface CO2 storage. I wi
 ll show the results of our global analyses of CO2 storage scaleup limited 
 by reservoir pressurisation or constraints on sustained annual growth in t
 he deployment of projects. I argue for both a standardised reporting of cu
 rrent carbon capture and storage activity and an inclusion of growth model
 ling and physics-based contraints in the projection of future scaleup in C
 O2 storage.
