資料簡介
為了實(shí)現(xiàn)將全球平均氣溫上升限制在不超過2攝氏度的溫室氣體減排目標(biāo),國際能源署(IEA)估計(jì),與能源有關(guān)的排放必須大幅度減少。為了實(shí)現(xiàn)這一目標(biāo),需要對(duì)若干技術(shù)進(jìn)行大規(guī)模投資,在成本最低的情況下,碳捕獲和儲(chǔ)存(CCS)在2050年所需的42 Gt減排中貢獻(xiàn)了7 Gt(圖1)。如果將CCS排除在電力行業(yè)的技術(shù)選擇之外,IEA表示,到2050年,投資成本將增加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.
