[...] The combustion of the coal in the presence of the sorbent facilitates the capture of sulphur dioxide (SO2). [...] The reacted sorbent is removed with the bed ash through the bottom of the boiler and with the fly ash that has been collected in the dust collectors at the top of the boiler stacks. [...] The CO2 rises to the top of the aquifer and, over tens to hundreds of years, eventually dissolves into the salty water, reacting with minerals in the formation to form stable compounds similar to carbonate.73 One example of commercially operated saline aquifer sequestration is the Sleipner Project operated by Statoil in the North Sea off the coast of Norway, where CO2 is compressed and pumped into
