GCCSI reports that 19 commercial CCS facilities are currently operating, three are under construction, and 36 are in development. Each of these facilities will store between hundreds of thousands and millions of tonnes of CO2 per year. The GCCSI estimates that, to date, 260 mega tonnes of CO2 (MtCO2) have been stored permanently in geological formations. The GCCSI points to continued improvements in CCS technology.
These are exemplified by a halving in capture costs for power stations over the past decade, with the next generation of technologies promising even lower costs.
According to the GCCSI, “the lowest-cost opportunities for CCS can deliver multi-million tonne CO2 abatement at a single facility, at a cost of less than US$ 20 per tonne.” The GCCSI points to the Intergovernmental Panel on Climate Change (IPCC) estimates of a cumulative geologic storage potential of over 1,200 GtCO2 this century.
