摘要:

目的 在“双碳”目标背景下,火电面临着巨大的减排压力。火电碳足迹评价能直观地表现火电的生命周期温室气体排放量,帮助挖掘减碳潜力。为此,对火电碳足迹评估的研究现状进行了综述。 方法 介绍了目前火电碳足迹评价依据的主要标准和方法,并对火电碳足迹评价流程进行了概述。综述了评价流程中存在的差异性问题并给出了部分建议。根据工艺流程将生命周期分为上游、核心和下游3个环节,由于核心环节碳排放集中度极高,部分情况下可以忽略燃煤电厂的建造、退役和电力输送环节的碳足迹。 结论 不同类型火力发电的生命周期相似,但垃圾焚烧发电碳足迹不包括生活垃圾的获取过程。无论哪种火电形式,在缺乏实测排放因子的情况下,建议排放因子选取国内外已发布的标准、文献和数据库的缺省值。

Abstract:

Objectives Under the background of the “double-carbon” target, thermal power is facing great pressure to reduce emissions. Thermal power carbon footprint evaluation can directly show the greenhouse gas emissions of thermal power and help tap the potential of carbon reduction. Therefore, the research status of thermal power carbon footprint assessment was reviewed. Methods This paper introduced the main standards and methods for thermal power footprint evaluation, and summarized the thermal power footprint evaluation process. The differences in the evaluation process were reviewed and some suggestions were given. The life cycle is divided into upstream, core and downstream. According to the high concentration of carbon emissions in the core links, the carbon footprint of the construction, decommissioning and power transmission of coal-fired power plants can be ignored in some cases. Conclusions The life cycle of different types of thermal power generation is similar, but the carbon footprint of waste incineration power generation does not include the acquisition process of domestic waste. Regardless of the form of thermal power, in the absence of measured emission factors, it is recommended that the emission factors select the default values of the published standards, literature and databases at home and abroad.
