Economic Potential of DACCS and Global CCS Progress
CAPTURE CAPACITY (MTPA)

Whilst the range of reservoir permeabilities and
thicknesses that have been utilised for CO2 storage is
quite broad, there appears to be a geological sweet spot at
a permeability of around 300 millidarcies and a formation
thickness of 100-200 metres. This combination may be
described quantitatively by injectivity potential which is
the mathematical product of reservoir permeability and
thickness. Most projects inject between 1 and 10 Mtpa
of CO2 into storage reservoirs with injectivity potential of
between 10 and 100 Darcy-metres according to Hoffman
et al. (2015) (2).
The diversity of storage types, geological conditions,
and injection rates will likely increase with the ongoing
development of storage resources across new
geographies and geological basins. Much like sectors
adopting CCS for decarbonisation, the geological sites
for storage are diversifying as more resources are
developed.
