摘要/Abstract

摘要： 從生命周期的角度分析，各類新能源發(fā)電技術(shù)的開發(fā)、建設(shè)、運(yùn)行過程，也會(huì)帶來一定的溫室氣體排放，這引發(fā)了人們對(duì)于新能源發(fā)電技術(shù)“低碳”屬性的擔(dān)憂。遵循生命周期評(píng)價(jià)方法，在對(duì)國內(nèi)外大量資料文獻(xiàn)進(jìn)行收集整理的基礎(chǔ)上，對(duì)中國傳統(tǒng)火電和主要新能源發(fā)電技術(shù)的溫室氣體排放系數(shù)進(jìn)行了對(duì)比分析；并根據(jù)國家發(fā)展規(guī)劃目標(biāo)，對(duì)新能源發(fā)電替代火電的溫室氣體減排潛力進(jìn)行了估算。分析結(jié)果表明，即使考慮生命周期內(nèi)的排放，新能源發(fā)電技術(shù)的溫室氣體排放系數(shù)仍遠(yuǎn)遠(yuǎn)低于火電，新能源發(fā)電技術(shù)替代火電的溫室氣體減排潛力巨大。

Abstract: From the perspective of life cycle assessment (LCA), the development, construction, operation of all kinds of new energy power generation technology do bring some greenhouse gas (GHG) emissions. This sparks "low carbon" property concerns of new energy power generation technology. Based on domestic and foreign relevant literature, this paper compares and estimates the GHG emission coefficients of traditional power generation and new energy power generation in China with the LCA, and then calculates the GHG mitigation potential of new energy power generation alternative to traditional coal-fired power generation, according to the national development planning objectives of new alternative energy generating. The results show that the GHG emission coefficients of new energy power generations are much lower than that of traditional coal-fired power generation even with LCA accounting, and the GHG mitigation potential of new energy substitution is still large.
