In response to the increase in the global concentrations of greenhouse gases, the IEA Greenhouse Gas R&D Programme is carrying out an assessment of greenhouse gas abatement technologies with particular reference to carbon dioxide emissions from fossil-fuel power generation systems. The Programme has examined, on a consistent basis, the options available for capturing and disposing of the CO{sub 2} product from a range of gas and coal fired power generation plant types, each with an output of 500MW(e). Systems under consideration include PF+FGD, IGCC, NGCC and a CO{sub 2}/O{sub 2} recycle scheme. CO{sub 2} capture technologies considered include chemical and physical absorption, solid adsorption, cryogenics, membrane separation and gas separation membranes. Carbon dioxide disposal options considered are; disposal in the oceans, in aquifers, in depleted gas reservoirs and terrestrial storage as a solid. In addition, a number of studies have evaluated the utilisation of CO{sub 2} for enhanced oil recovery and the manufacture of chemicals, including a detailed investigation of dimethyl carbonate production. Comparison is also made with the alternative stance of compensatory forest plantations and substitution of fossil fuels with biomass. Emphasis has been placed on a requirement to determine the impact of the various technologies on the cost of electricity generation. This has been achieved by analysing the core of specific schemes, on a common basis, and comparative results are presented for various CO{sub 2} abatement options. A member of studies have also been carried out to evaluate transport options and the environmental impact of these technology combinations for carbon dioxide disposal. The results indicate that by combining the most favourable technologies for CO{sub 2} capture and disposal to efficient power generation technology, electricity generation costs could be increased by around 50%. Alternative schemes have similar or even greater cost penalties.
