Due to high sorbent costs, however, additional thermal energy is required to regenerate the saturated sorbent to make it reusable, and electricity is also needed to operate the capture unit. In oxy-fuel capture, oxygen is separated from air prior to combustion, so that flue-gases are composed of mainly CO 2 and water, making capture easier.
