THE FULL FUEL-CYCLE OF CO2 CAPTURE AND DISPOSAL .3. AFFORESTATION, AND ENVIRONMENTAL IMPACTS

This paper reports on the assessment and valuation of the environmenta l impacts arising from the full fuel cycles of three fossil fuelled po wer plants equipped with CO2 capture and disposal facilities. The firs t of these is a Natural Gas Combined Cycle (NGCC) plant featuring CO2 separation and disposal to a disused gas well. The second is an Integr ated Gasification Combined Cycle (IGCC) plant featuring CO2 separation and disposal to the deep ocean. The third case is a pulverised fuel p lant with flue gas desulphurisation (PF+FGD) with CO2 capture by a man aged forest at a site remote from the power plant. A wide variety of i mpacts have been assessed at local, regional and global scales. They i nclude accidents affecting workers and the public, the effects of atmo spheric emissions on health and buildings and the impacts of global wa rming. Issues associated with management of the forest designed to cap ture CO2 from the PF plant and assessment of the associated costs are also described.
