摘要

This paper analyses the role of CO_2 capture and storage (CCS) for 15 world regions, using the IEA Secretariat's Energy Technology Perspectives (ETP) model. This bottom-up model describes global energy supply and demand for the period 2000-2050. The results suggest that if CCS technologies meet development targets and CO_2 abatement policies are introduced at a level of 50$/t CO_2, fossil fuelled power plants with CO_2 capture will represent up to 21% of global electricity production by 2030 and 37% by 2050. Deployment of CCS technologies in the electricity sector will result in increased fossil fuel use for two reasons: availability of CCS allows for wider utilisation of fossil fuels for power generation and more fuel is needed to cover CCS energy requirements. By 2050, coal use will increase by up to 175% in comparison to scenarios without CCS technologies but with similar policy incentives. Renewables grow at a high rate, but less than in the scenario without CCS. Slightly slower growth of renewables in the scenario with CCS available does not mean higher CO_2 emissions. On the contrary, in 2050, the energy system with CCS available emits 7.9 Gt CO_2 per year less than the same system without CCS available (both systems operate with US$50/t CO_2 policy incentives). Moreover, if reduced externalities are included in calculations, the total system costs with CCS available are lower than for the system without CCS. If cumulative emissions are fixed in the calculations, the undiscounted cumulative system costs for a scenario with CCS are 39% lower than for a scenario without CCS. This means that the introduction of CCS brings both environmental and economic benefits if CO_2 is given a price. Various sensitivity analyses show the robustness of CCS in the policy mix. Thus, this study recommends that policies be further developed so CCS technology can be applied in practice.
