资料简介

为了实现将全球平均气温上升限制在不超过2摄氏度的温室气体减排目标,国际能源署(IEA)估计,与能源有关的排放必须大幅度减少。为了实现这一目标,需要对若干技术进行大规模投资,在成本最低的情况下,碳捕获和储存(CCS)在2050年所需的42 Gt减排中贡献了7 Gt(图1)。如果将CCS排除在电力行业的技术选择之外,IEA表示,到2050年,投资成本将增加40%。

To achieve greenhouse gas (GHG) emission reduction targets limiting a global average temperature rise to no more than 2C, the International Energy Agency (IEA) estimates that energy-related emissions must reduce very substantially. Large-scale investments in several technologies are required in order to meet this target, with carbon capture and storage (CCS) contributing 7 Gt of the required 42 Gt emission reduction in 2050 in a least cost scenario (Figure 1). If CCS were to be excluded as a technology option in the electricity sector, the IEA states that investment costs over the period to 2050 would increase by 40 per cent.
