Cold short-ut to CO2 storage

CO2 capture based on refrigeration has a number of potential applications. The figure shows how CO2 can be removed from gasified coal – i.e. coal which has been transformed into gas. Once CO2 is condensed, the remaining fuel gas can be burnt in a gas turbine power plant. Since the fuel is virtually free from CO2, there will be next to no CO2 in the power’s station’s flue-gases either. Illustration: SINTEF Energy Research.
